Psoriasis Treatment, Causes, Pictures, Symptoms, Types & Diet

Psoriasis facts

What is psoriasis?

Psoriasis is a noncontagious, chronic skin disease that produces plaques of thickened, scaly skin. The dry flakes of silvery-white skin scales result from the excessively rapid proliferation of skin cells. Psoriasis is fundamentally an immune system problem. The proliferation of skin cells is triggered by inflammatory chemicals produced by specialized white blood cells called T-cells. Psoriasis commonly affects the skin of the elbows, knees, and scalp.

The spectrum of this autoimmune disease ranges from mild with limited involvement of small areas of skin to severe psoriasis with large, thick plaques to red inflamed skin affecting the entire body surface.

Psoriasis is considered an incurable, long-term (chronic) inflammatory skin condition. It has a variable course, periodically improving and worsening. It is not unusual for psoriasis to spontaneously clear for years and stay in remission. Many people note a worsening of their symptoms in the colder winter months.

Psoriasis, an immune-mediated inflammatory disease, affects all races and both sexes. Although psoriasis can be seen in people of any age, from babies to seniors, most commonly patients are first diagnosed in their early adult years. The self-esteem and quality of life of patients with psoriasis is often diminished because of the appearance of their skin. Recently, it has become clear that people with psoriasis are more likely to have diabetes, high blood lipids, cardiovascular disease, and a variety of other inflammatory diseases. This may reflect an inability to control inflammation. Caring for psoriasis takes medical teamwork.

No. Psoriasis is not contagious. Psoriasis is not transmitted sexually or by physical contact. Psoriasis is not caused by lifestyle, diet, or bad hygiene.

While the exact cause of psoriasis is unknown, researchers consider environmental, genetic, and immune system factors as playing roles in the establishment of the disease.

What are psoriasis causes and risk factors?

The exact cause remains unknown. A combination of elements, including genetic predisposition and environmental factors, are involved. It is common for psoriasis to be found in members of the same family. Defects in the immune system and the control of inflammation are thought to play major roles. Certain medications like beta-blockers have been linked to psoriasis. Despite research over the past 30 years, the "master switch" that turns on psoriasis is still a mystery.

What are the different types of psoriasis?

There are several different forms of psoriasis, including plaque psoriasis or psoriasis vulgaris (common type), guttate psoriasis (small, drop-like spots), inverse psoriasis (in the folds like of the underarms, navel, groin, and buttocks), and pustular psoriasis (small pus-filled yellowish blisters). When the palms and the soles are involved, this is known as palmoplantar psoriasis. In erythrodermic psoriasis, the entire skin surface is involved with the disease. Patients with this form of psoriasis often feel cold and may develop congestive heart failure if they have a preexisting heart problem. Nail psoriasis produces yellow pitted nails that can be confused with nail fungus. Scalp psoriasis can be severe enough to produce localized hair loss, plenty of dandruff, and severe itching.

Can psoriasis affect my joints?

Yes, psoriasis is associated with inflamed joints in about one-third of those affected. In fact, sometimes joint pains may be the only sign of the disorder, with completely clear skin. The joint disease associated with psoriasis is referred to as psoriatic arthritis. Patients may have inflammation of any joints (arthritis), although the joints of the hands, knees, and ankles tend to be most commonly affected. Psoriatic arthritis is an inflammatory, destructive form of arthritis and needs to be treated with medications in order to stop the disease progression.

The average age for onset of psoriatic arthritis is 30-40 years of age. Usually, the skin symptoms and signs precede the onset of the arthritis.

Can psoriasis affect only my nails?

Yes, psoriasis may involve solely the nails in a limited number of patients. Usually, the nail signs accompany the skin and arthritis symptoms and signs. Nail psoriasis is typically very difficult to treat. Treatment options are somewhat limited and include potent topical steroids applied at the nail-base cuticle, injection of steroids at the nail-base cuticle, and oral or systemic medications as described below for the treatment of psoriasis.

What are psoriasis symptoms and signs? What does psoriasis look like?

Plaque psoriasis signs and symptoms appear as red or pink small scaly bumps that merge into plaques of raised skin. Plaque psoriasis classically affects skin over the elbows, knees, and scalp and is often itchy. Although any area may be involved, plaque psoriasis tends to be more common at sites of friction, scratching, or abrasion. Sometimes pulling off one of these small dry white flakes of skin causes a tiny blood spot on the skin. This is a special diagnostic sign in psoriasis called the Auspitz sign.

Fingernails and toenails often exhibit small pits (pinpoint depressions) and/or larger yellowish-brown separations of the nail from the nail bed at the fingertip called distal onycholysis. Nail psoriasis may be confused with and incorrectly diagnosed as a fungal nail infection.

Guttate psoriasis symptoms and signs include bumps or small plaques ( inch or less) of red itchy, scaling skin that may appear explosively, affecting large parts of the skin surface simultaneously, after a sore throat.

In inverse psoriasis, genital lesions, especially in the groin and on the head of the penis, are common. Psoriasis in moist areas like the navel or the area between the buttocks (intergluteal folds) may look like flat red plaques without much scaling. This may be confused with other skin conditions like fungal infections, yeast infections, allergic rashes, or bacterial infections.

Symptoms and signs of pustular psoriasis include at rapid onset of groups of small bumps filled with pus on the torso. Patients are often systemically ill and may have a fever.

Erythrodermic psoriasis appears as extensive areas of red skin often involving the entire skin surface. Patients may often feel chilled.

Scalp psoriasis may look like severe dandruff with dry flakes and red areas of skin. It can be difficult to differentiate between scalp psoriasis and seborrheic dermatitis when only the scalp is involved. However, the treatment is often very similar for both conditions.

How do health care professionals diagnose psoriasis?

The diagnosis of psoriasis is typically made by obtaining information from the physical examination of the skin, medical history, and relevant family health history.

Sometimes lab tests, including a microscopic examination of skin cells obtained from a skin biopsy, may be necessary.

Eczema vs. psoriasis

Occasionally, it can be difficult to differentiate eczematous dermatitis from psoriasis. This is when a biopsy can be quite valuable to distinguish between the two conditions. Of note, both eczematous dermatitis and psoriasis often respond to similar treatments. Certain types of eczematous dermatitis can be cured where this is not the case for psoriasis.

How many people have psoriasis?

Psoriasis is a fairly common skin condition and is estimated to affect approximately 1%-3% of the U.S. population. It currently affects roughly 7.5 million to 8.5 million people in the U.S. It is seen worldwide in about 125 million people. Interestingly, African Americans have about half the rate of psoriasis as Caucasians.

Is psoriasis contagious?

No. A person cannot catch it from someone else, and one cannot pass it to anyone else by skin-to-skin contact. Directly touching someone with psoriasis every day will never transmit the condition.

Is there a cure for psoriasis?

No, psoriasis is not currently curable. However, it can go into remission, producing an entirely normal skin surface. Ongoing research is actively making progress on finding better treatments and a possible cure in the future.

Is psoriasis hereditary?

Although psoriasis is not contagious from person to person, there is a known hereditary tendency. Therefore, family history is very helpful in making the diagnosis.

What health care specialists treat psoriasis?

Dermatologists are doctors who specialize in the diagnosis and treatment of psoriasis, and rheumatologists specialize in the treatment of joint disorders and psoriatic arthritis. Many kinds of doctors may treat psoriasis, including dermatologists, family physicians, internal medicine physicians, rheumatologists, and other medical doctors. Some patients have also seen other allied health professionals such as acupuncturists, holistic practitioners, chiropractors, and nutritionists.

The American Academy of Dermatology and the National Psoriasis Foundation are excellent sources to help find doctors who specialize in this disease. Not all dermatologists and rheumatologists treat psoriasis. The National Psoriasis Foundation has one of the most up-to-date databases of current psoriasis specialists.

It is now apparent that patients with psoriasis are prone to a variety of other disease conditions, so-called comorbidities. Cardiovascular disease, diabetes, hypertension, inflammatory bowel disease, hyperlipidemia, liver problems, and arthritis are more common in patients with psoriasis. It is very important for all patients with psoriasis to be carefully monitored by their primary care providers for these associated illnesses. The joint inflammation of psoriatic arthritis and its complications are frequently managed by rheumatologists.

What are psoriasis treatment options?

There are many effective psoriasis treatment choices. The best treatment is individually determined by the treating doctor and depends, in part, on the type of disease, the severity, and amount of skin involved and the type of insurance coverage.

For mild disease that involves only small areas of the body (less than 10% of the total skin surface), topical treatments (skin applied), such as creams, lotions, and sprays, may be very effective and safe to use. Occasionally, a small local injection of steroids directly into a tough or resistant isolated psoriatic plaque may be helpful.

For moderate to severe psoriasis that involves much larger areas of the body (>10% or more of the total skin surface), topical products may not be effective or practical to apply. This may require ultraviolet light treatments or systemic (total body treatments such as pills or injections) medicines. Internal medications usually have greater risks. Because topical therapy has no effect on psoriatic arthritis, systemic medications are generally required to stop the progression to permanent joint destruction.

It is important to keep in mind that as with any medical condition, all medicines carry possible side effects. No medication is 100% effective for everyone, and no medication is 100% safe. The decision to use any medication requires thorough consideration and discussion with your health care provider. The risks and potential benefit of medications have to be considered for each type of psoriasis and the individual. Of two patients with precisely the same amount of disease, one may tolerate it with very little treatment, while the other may become incapacitated and require treatment internally.

A proposal to minimize the toxicity of some of these medicines has been commonly called "rotational" therapy. The idea is to change the anti-psoriasis drugs every six to 24 months in order to minimize the toxicity of one medication. Depending on the medications selected, this proposal can be an option. An exception to this proposal is the use of the newer biologic medications as described below. An individual who has been using strong topical steroids over large areas of their body for prolonged periods may benefit from stopping the steroids for a while and rotating onto a different therapy.

What creams, lotions, and home remedies are available for psoriasis?

Topical (skin applied) treatments include topical corticosteroids, vitamin D analogue creams like calcipotriene (Calcitrene, Dovonex, Sorilux), topical retinoids (tazarotene [Tazorac]), moisturizers, topical immunomodulators (tacrolimus and pimecrolimus), coal tar, anthralin, and others.

Are psoriasis shampoos available?

Coal tar shampoos are very useful in controlling psoriasis of the scalp. Using the shampoo daily can be very beneficial adjunctive therapy. There are a variety of over-the-counter shampoos available without a prescription. There is no evidence that one shampoo is superior to another. Generally, the selection of a tar shampoo is simply a matter of personal preference.

What oral medications are available for psoriasis?

Oral medications include methotrexate (Trexall), acitretin (Soriatane), cyclosporine (Neoral), apremilast (Otezla), and others. Oral prednisone (corticosteroid) is generally not used in psoriasis and may cause a disease flare-up if administered.

What injections or infusions are available for psoriasis?

Recently, a new group of drugs called biologics have become available to treat psoriasis and psoriatic arthritis. They are produced by living cells cultures in an industrial setting. They are all proteins and therefore must be administered through the skin because they would otherwise be degraded during digestion. All biologics work by suppressing certain specific portions of the immune inflammatory response that are overactive in psoriasis. A convenient method of categorizing these drugs is on the basis of their site of action:

Drug choice can be complicated, and your physician will help in selecting the best option. In some patients. it may be possible to predict drug efficacy on the basis of a prospective patient's genetics. It appears that the presence of the HLA-Cw6 gene is correlated with a beneficial response to ustekinumab.

Newer drugs are in development and no doubt will be available in the near future. As this class of drugs is fairly new, ongoing monitoring and adverse effect reporting continues and long-term safety continues to be monitored. Biologics are all comparatively expensive especially in view of the fact they none of them are curative. Recently, the FDA has attempted to address this problem by permitting the use of "biosimilar" drugs. These drugs are structurally identical to a specific biologic drug and are presumed to produce identical therapeutic responses in human beings to the original, but are produced using different methodology. Biosimilars ought to be available at some fraction of the cost of the original. If this will be an effective approach remains to be seen. The only biosimilar available currently is infliximab (Inflectra). Two other biosimilar drugs have been accepted by the FDA, an etanercept equivalent (Erelzi) and an adalimumab equivalent (Amjevita) -- but currently, neither are available.

Some biologics are to be administered by self-injections for home use while others are given by intravenous infusions in the doctor's office. Biologics have some screening requirements such as a tuberculosis screening test (TB skin test or PPD test) and other labs prior to starting therapy. As with any drug, side effects are possible with all biologic drugs. Common potential side effects include mild local injection-site reactions (redness and tenderness). There is concern of serious infections and potential malignancy with nearly all biologic drugs. Precautions include patients with known or suspected hepatitis B infection, active tuberculosis, and possibly HIV/AIDS. As a general consideration, these drugs may not be an ideal choice for patients with a history of cancer and patients actively undergoing cancer therapy. In particular, there may be an increased association of lymphoma in patients taking a biologic.

Biologics are expensive medications ranging in price from several to tens of thousands of dollars per year per person. Their use may be limited by availability, cost, and insurance approval. Not all insurance drug plans fully cover these drugs for all conditions. Patients need to check with their insurance and may require a prior authorization request for coverage approval. Some of the biologic manufacturers have patient-assistance programs to help with financial issues. Therefore, choice of the right medication for your condition depends on many factors, not all of them medical. Additionally, convenience of receiving the medication and lifestyle affect the choice of the right biologic medication.

Is there an anti-psoriasis diet?

Most patients with psoriasis seem to be overweight. Since there is a predisposition for those patients to develop cardiovascular disease and diabetes, it is suggested strongly that they try to maintain a normal body weight. Although evidence is sparse, it has been suggested that slender patients are more likely to respond to treatment.

Although dietary studies are notoriously difficult to perform and interpret, it seems likely that an anti-inflammatorydiet whose fat content is composed of polyunsaturated oils like olive oil and fish oil is beneficial for psoriasis. The so-called Mediterranean diet is an example.

What about light therapy for psoriasis?

Light therapy is also called phototherapy. There are several types of medical light therapies that include PUVA (an acronym for psoralen + UVA), UVB, and narrow-band UVB. These artificial light sources have been used for decades and generally are available in only certain physician's offices. There are a few companies who may sell light boxes or light bulbs for prescribed home light therapy.

Natural sunlight is also used to treat psoriasis. Daily short, controlled exposures to natural sunlight may help or clear psoriasis in some patients. Skin unaffected by psoriasis and sensitive areas such as the face and hands may need to be protected during sun exposure.

There are also multiple newer light sources like lasers and photodynamic therapy (use of a light activating medication and a special light source) that have been used to treat psoriasis.

PUVA is a special treatment using a photosensitizing drug and timed artificial-light exposure composed of wavelengths of ultraviolet light in the UVA spectrum. The photosensitizing drug in PUVA is called psoralen. Both the psoralen and the UVA light must be administered within one hour of each other for a response to occur. These treatments are usually given in a physician's office two to three times per week. Several weeks of PUVA is usually required before seeing significant results. The light exposure time is gradually increased during each subsequent treatment. Psoralens may be given orally as a pill or topically as a bath or lotion. After a short incubation period, the skin is exposed to a special wavelength of ultraviolet light called UVA. Patients using PUVA are generally sun sensitive and must avoid sun exposure for a period of time after PUVA. Common side effects with PUVA include burning, aging of the skin, increased brown spots called lentigines, and an increased risk of skin cancer, including melanoma. The relative increase in skin cancer risk with PUVA treatment is controversial. PUVA treatments need to be closely monitored by a physician and discontinued when a maximum number of treatments have been reached.

Narrow-band UVB phototherapy is an artificial light treatment using very limited wavelengths of light. It is frequently given daily or two to three times per week. UVB is also a component of natural sunlight. UVB dosage is based on time and exposure is gradually increased as tolerated. Potential side effects with UVB include skin burning, premature aging, and possible increased risk of skin cancer. The relative increase in skin cancer risk with UVB treatment needs further study but is probably less than PUVA or traditional UVB.

Sometimes UVB is combined with other treatments such as tar application. Goeckerman is a special psoriasis therapy using this combination. Some centers have used this therapy in a "day care" type of setting where patients are in the psoriasis treatment clinic all day for several weeks and go home each night.

Recently, a laser (excimer laser XTRAC) has been developed that generates ultraviolet light in the same range as narrow-band ultraviolet light. This light can be beneficial for psoriasis localized to small areas of skin like the palms, soles, and scalp. It is impractical to use in in extensive disease.

What is the long-term prognosis with psoriasis? What are complications of psoriasis?

Overall, the prognosis for most patients with psoriasis is good. While it is not curable, it is controllable. As described above, recent studies show an association of psoriasis and other medical conditions, including obesity, diabetes, and heart disease.

Is it possible to prevent psoriasis?

Since psoriasis is inherited, it is impossible at this time to suggest anything that is likely to prevent its development aside from indulging in a healthy lifestyle.

What does the future hold for psoriasis?

Psoriasis research is heavily funded and holds great promise for the future. Just the last five to 10 years have produced great improvements in treatment of the disease with medications aimed at controlling precise sites of the process of inflammation. Ongoing research is needed to decipher the ultimate underlying cause of this disease.

Is there a national psoriasis support group?

Yes, the National Psoriasis Foundation (NPF) is an organization dedicated to helping patients with psoriasis and furthering research in this field. They hold national and local chapter meetings. The NPF web site (http://www.psoriasis.org/home/) shares up-to-date reliable medical information and statistics on the condition.

Where can people get more information on psoriasis?

A dermatologist, the American Academy of Dermatology at http://www.AAD.org, and the National Psoriasis Foundation at http://www.psoriasis.org/home/ may be excellent sources of more information.

There are many ongoing clinical trials for psoriasis all over the United States and in the world. Many of these clinical trials are ongoing at academic or university medical centers and are frequently open to patients without cost.

Clinical trials frequently have specific requirements for types and severity of psoriasis that may be enrolled into a specific trial. Patients need to contact these centers and inquire regarding the specific study requirements. Some studies have restrictions on what recent medications have been used for psoriasis, current medication, and overall health.

Some of the many medical centers in the U.S. offering clinical trials for psoriasis include the University of California, San Francisco Department of Dermatology, the University of California, Irvine Department of Dermatology, and the St. Louis University Medical School.

Psoriasis – Symptoms and causes – Mayo Clinic

Overview

Psoriasis is a common skin condition that speeds up the life cycle of skin cells. It causes cells to build up rapidly on the surface of the skin. The extra skin cells form scales and red patches that are itchy and sometimes painful.

Psoriasis is a chronic disease that often comes and goes. The main goal of treatment is to stop the skin cells from growing so quickly.

There is no cure for psoriasis, but you can manage symptoms. Lifestyle measures, such as moisturizing, quitting smoking and managing stress, may help.

Psoriasis care at Mayo Clinic

Psoriasis signs and symptoms are different for everyone. Common signs and symptoms include:

Psoriasis patches can range from a few spots of dandruff-like scaling to major eruptions that cover large areas.

Most types of psoriasis go through cycles, flaring for a few weeks or months, then subsiding for a time or even going into complete remission.

There are several types of psoriasis. These include:

Guttate psoriasis. This type primarily affects young adults and children. It's usually triggered by a bacterial infection such as strep throat. It's marked by small, water-drop-shaped, scaling lesions on your trunk, arms, legs and scalp.

The lesions are covered by a fine scale and aren't as thick as typical plaques are. You may have a single outbreak that goes away on its own, or you may have repeated episodes.

Pustular psoriasis. This uncommon form of psoriasis can occur in widespread patches (generalized pustular psoriasis) or in smaller areas on your hands, feet or fingertips.

It generally develops quickly, with pus-filled blisters appearing just hours after your skin becomes red and tender. The blisters may come and go frequently. Generalized pustular psoriasis can also cause fever, chills, severe itching and diarrhea.

If you suspect that you may have psoriasis, see your doctor for an examination. Also, talk to your doctor if your psoriasis:

Seek medical advice if your signs and symptoms worsen or don't improve with treatment. You may need a different medication or a combination of treatments to manage the psoriasis.

Viven Williams: Your fingernails are clues to your overall health. Many people develop lines or ridges from the cuticle to the tip.

Rachel Miest, M.D.: Those are actually completely fine and just a part of normal aging.

Viven Williams: But Dr. Rachel Miest says there are other nail changes you should not ignore that may indicate

Rachel Miest, M.D.: liver problems, kidney problems, nutritional deficiencies ...

Viven Williams: and other issues. Here are six examples: No. 1 is pitting. This could be a sign of psoriasis. Two is clubbing. Clubbing happens when your oxygen is low and could be a sign of lung issues. Three is spooning. It can happen if you have iron-deficient anemia or liver disease. Four is called "a Beau's line." It's a horizontal line that indicates a previous injury or infection. Five is nail separation. This may happen as a result of injury, infection or a medication. And six is yellowing of the nails, which may be the result of chronic bronchitis.

For the Mayo Clinic News Network, I'm Vivien Williams.

The cause of psoriasis isn't fully understood, but it's thought to be related to an immune system problem with T cells and other white blood cells, called neutrophils, in your body.

T cells normally travel through the body to defend against foreign substances, such as viruses or bacteria.

But if you have psoriasis, the T cells attack healthy skin cells by mistake, as if to heal a wound or to fight an infection.

Overactive T cells also trigger increased production of healthy skin cells, more T cells and other white blood cells, especially neutrophils. These travel into the skin causing redness and sometimes pus in pustular lesions. Dilated blood vessels in psoriasis-affected areas create warmth and redness in the skin lesions.

The process becomes an ongoing cycle in which new skin cells move to the outermost layer of skin too quickly in days rather than weeks. Skin cells build up in thick, scaly patches on the skin's surface, continuing until treatment stops the cycle.

Just what causes T cells to malfunction in people with psoriasis isn't entirely clear. Researchers believe both genetics and environmental factors play a role.

Psoriasis typically starts or worsens because of a trigger that you may be able to identify and avoid. Factors that may trigger psoriasis include:

Anyone can develop psoriasis, but these factors can increase your risk of developing the disease:

If you have psoriasis, you're at greater risk of developing certain diseases. These include:

Psoriasis - Symptoms and causes - Mayo Clinic

Psoriasis Guide: Causes, Symptoms and Treatment Options

Medically reviewed on May 14, 2018

Psoriasis is a chronic skin disorder that causes scaling and inflammation.

Psoriasis may develop as a result of an abnormality in the body's immune system. The immune system normally fights infection and allergic reactions.

Psoriasis probably has a genetic component. Nearly half of patients have family members with psoriasis.

Certain medications may trigger psoriasis. Other medications seem to make psoriasis worse in people who have the disease.

Psoriasis causes skin scaling and inflammation. It may or may not cause itching. There are several types of psoriasis:

Plaque psoriasis. In plaque psoriasis, there are rounded or oval patches (plaques) of affected skin. These are usually red and covered with a thick silvery scale. The plaques often occur on the elbows, knees, scalp or near the buttocks. They may also appear on the trunk, arms and legs.

Inverse psoriasis. Inverse psoriasis is a plaque type of psoriasis that tends to affect skin creases. Creases in the underarm, groin, buttocks, genital areas or under the breast are particularly affected. The red patches may be moist rather than scaling.

Pustular psoriasis. The skin patches are studded with pimples or pustules.

Guttate psoriasis. In guttate psoriasis, many small, red, scaly patches develop suddenly and simultaneously. Guttate psoriasis often occurs in a young person who has recently had strep throat or a viral upper respiratory infection.

About half of people with skin symptoms of psoriasis also have abnormal fingernails. Their nails are often thick and have small indentations, called pitting.

A type of arthritis called psoriatic arthritis affects some people with psoriasis. Psoriatic arthritis may occur before skin changes appear.

Your doctor will look for the typical skin and nail changes of this disorder. He or she can frequently diagnose psoriasis based on your physical examination.

When skin symptoms are not typical of the disorder, your doctor may recommend a skin biopsy. In a biopsy, a small sample of skin is removed and examined in a laboratory. The biopsy can confirm the diagnosis and rule out other possible skin disorders.

Psoriasis is a long-term disorder. However, symptoms may come and go.

There is no way to prevent psoriasis.

Treatment for psoriasis varies depending on the:

Treatments for psoriasis include:

Topical treatments. These are treatments applied directly to the skin.

Daily skin care with emollients for lubrication. These include petroleum jelly or unscented moisturizers.

Corticosteroid creams, lotions and ointments. These may be prescribed in medium and high-strength forms for stubborn plaques on the hands, feet, arms, legs and trunk. They may be prescribed in low-strength forms for areas of delicate skin such as the face.

Calcipotriol (Dovonex) slows production of skin scales.

Tazarotene (Tazorac) is a synthetic vitamin A derivative.

Coal tar

Salicylic acid to remove scales

Phototherapy. Extensive or widespread psoriasis may be treated with light. Phototherapy uses ultraviolet B or ultraviolet A, alone or in combination with coal tar.

A treatment called PUVA combines ultraviolet A light treatment with an oral medication that improves the effectiveness of the light treatment.

Laser treatment also can be used. It allows treatment to be more focused so that higher amounts of UV light can be used.

Vitamin A derivatives. These are used to treat moderate to severe psoriasis involving large areas of the body. These treatments are very powerful. Some have the potential to cause severe side effects. It's essential to understand the risks and be monitored closely.

Immunosuppressants. These drugs work by suppressing the immune system. They are used to treat moderate to severe psoriasis involving large areas of the body.

Antineoplastic agents. More rarely, these drugs (which are most often used to treat cancer cells) may be prescribed for severe psoriasis.

Biologic therapies. Biologics are newer agents used for psoriasis that has not responded to other treatments. Psoriasis is caused, in part, by substances made by the immune system that cause inflammation. Biologics act against these substances. Biologic treatments tend to be quite expensive.

If you are unsure whether you have psoriasis, contact your doctor. Also contact your doctor if you have psoriasis and are not doing well with over-the-counter treatment.

For most patients, psoriasis is a long-term condition.

There is no cure. But there are many effective treatments.

In some patients, doctors may switch treatments every 12 to 24 months. This prevents the treatments from losing their effectiveness and decreases the risk of side effects.

Psoriasis Guide: Causes, Symptoms and Treatment Options

Psoriasis – Diagnosis and treatment – Mayo Clinic

Diagnosis

In most cases, diagnosis of psoriasis is fairly straightforward.

Psoriasis treatments reduce inflammation and clear the skin. Treatments can be divided into three main types: topical treatments, light therapy and systemic medications.

Used alone, creams and ointments that you apply to your skin can effectively treat mild to moderate psoriasis. When the disease is more severe, creams are likely to be combined with oral medications or light therapy. Topical psoriasis treatments include:

Topical corticosteroids. These drugs are the most frequently prescribed medications for treating mild to moderate psoriasis. They reduce inflammation and relieve itching and may be used with other treatments.

Mild corticosteroid ointments are usually recommended for sensitive areas, such as your face or skin folds, and for treating widespread patches of damaged skin.

Your doctor may prescribe stronger corticosteroid ointment for smaller, less sensitive or tougher-to-treat areas.

Long-term use or overuse of strong corticosteroids can cause thinning of the skin. Topical corticosteroids may stop working over time. It's usually best to use topical corticosteroids as a short-term treatment during flares.

Topical retinoids. These are vitamin A derivatives that may decrease inflammation. The most common side effect is skin irritation. These medications may also increase sensitivity to sunlight, so while using the medication apply sunscreen before going outdoors.

The risk of birth defects is far lower for topical retinoids than for oral retinoids. But tazarotene (Tazorac, Avage) isn't recommended when you're pregnant or breast-feeding or if you intend to become pregnant.

Calcineurin inhibitors. Calcineurin inhibitors tacrolimus (Prograf) and pimecrolimus (Elidel) reduce inflammation and plaque buildup.

Calcineurin inhibitors are not recommended for long-term or continuous use because of a potential increased risk of skin cancer and lymphoma. They may be especially helpful in areas of thin skin, such as around the eyes, where steroid creams or retinoids are too irritating or may cause harmful effects.

Coal tar. Derived from coal, coal tar reduces scaling, itching and inflammation. Coal tar can irritate the skin. It's also messy, stains clothing and bedding, and has a strong odor.

Coal tar is available in over-the-counter shampoos, creams and oils. It's also available in higher concentrations by prescription. This treatment isn't recommended for women who are pregnant or breast-feeding.

This treatment uses natural or artificial ultraviolet light. The simplest and easiest form of phototherapy involves exposing your skin to controlled amounts of natural sunlight.

Other forms of light therapy include the use of artificial ultraviolet A (UVA) or ultraviolet B (UVB) light, either alone or in combination with medications.

Psoralen plus ultraviolet A (PUVA). This form of photochemotherapy involves taking a light-sensitizing medication (psoralen) before exposure to UVA light. UVA light penetrates deeper into the skin than does UVB light, and psoralen makes the skin more responsive to UVA exposure.

This more aggressive treatment consistently improves skin and is often used for more-severe cases of psoriasis. Short-term side effects include nausea, headache, burning and itching. Long-term side effects include dry and wrinkled skin, freckles, increased sun sensitivity, and increased risk of skin cancer, including melanoma.

If you have severe psoriasis or it's resistant to other types of treatment, your doctor may prescribe oral or injected drugs. This is known as systemic treatment. Because of severe side effects, some of these medications are used for only brief periods and may be alternated with other forms of treatment.

Although doctors choose treatments based on the type and severity of psoriasis and the areas of skin affected, the traditional approach is to start with the mildest treatments topical creams and ultraviolet light therapy (phototherapy) in those patients with typical skin lesions (plaques) and then progress to stronger ones only if necessary. Patients with pustular or erythrodermic psoriasis or associated arthritis usually need systemic therapy from the beginning of treatment. The goal is to find the most effective way to slow cell turnover with the fewest possible side effects.

There are a number of new medications currently being researched that have the potential to improve psoriasis treatment. These treatments target different proteins that work with the immune system.

A number of alternative therapies claim to ease the symptoms of psoriasis, including special diets, creams, dietary supplements and herbs. None have definitively been proved effective. But some alternative therapies are deemed generally safe, and they may be helpful to some people in reducing signs and symptoms, such as itching and scaling. These treatments would be most appropriate for those with milder, plaque disease and not for those with pustules, erythroderma or arthritis.

If you're considering dietary supplements or other alternative therapy to ease the symptoms of psoriasis, consult your doctor. He or she can help you weigh the pros and cons of specific alternative therapies.

Explore Mayo Clinic studies testing new treatments, interventions and tests as a means to prevent, detect, treat or manage this disease.

Although self-help measures won't cure psoriasis, they may help improve the appearance and feel of damaged skin. These measures may benefit you:

Coping with psoriasis can be a challenge, especially if the disease covers large areas of your body or is in places readily seen by other people, such as your face or hands. The ongoing, persistent nature of the disease and the treatment challenges only add to the burden.

Here are some ways to help you cope and to feel more in control:

You'll likely first see your family doctor or a general practitioner. In some cases, you may be referred directly to a specialist in skin diseases (dermatologist).

Here's some information to help you prepare for your appointment and to know what to expect from your doctor.

New SETI Plan: Detect Alien Starships Powered by Black Holes

A new paper suggests that we could spot an alien civilization by looking for signs of starships powered by the radiation thrown off by small black hole.

Alien Starships

To detect alien civilizations, astronomers need to make some assumptions about the forms they might take — and the traces their technological artifacts could leave behind.

An outrageous new paper by a mathematician at Kansas State University does just that, positing that a sufficiently advanced alien civilization would likely build starships powered by the radiation thrown off by small black holes — and speculating that astronomers could use gamma telescopes to spot evidence of these black hole starships.

Black Holes

The basic idea, according to mathematician Louis Crane, is that a spaceship powered by a black hole would leave distinctive spillover from gamma rays. He suggests astronomers could detect that spillover using a telescope like the orbital Fermi Gamma-ray Space Telescope.

“If some advanced civilization already had such starships, current [very high energy] gamma ray telescopes could detect it out to 100 to 1,000 light years if we were in its beam,” Crane said in a press release. “They could be distinguished from natural sources by their steadily changing redshift over a period of years to decades.”

Game SETI Match

Crane also said, provocatively, that he believes astronomers may have already spotted several gamma ray sources “for which no natural explanation has been given.”

He also speculated about what it would mean for a civilization to be capable of creating an artificial black hole — and it sounds absolutely epic.

“To produce an artificial black hole, we would need to focus a billion-ton gamma ray laser to nuclear dimensions,” Crane said in the press release. “It’s like making as many high-tech nuclear bombs as there are automobiles on Earth. Just the scale of it is beyond the current world economy. A civilization which fully utilized the solar system would have the resources.”

Boeing Is Prepping to Launch Astronauts to Space Station

Commercial Crew Program

SpaceX isn’t the only company attempting to revolutionize the way we send astronauts to space.

Boeing, the largest aerospace company in the world, is looking to send up its own take on a passenger spacecraft, which it calls the CST-100 Starliner, to the International Space Station. Boeing is planning to launch the capsule — uncrewed for now, as a test flight — on an Atlas 5 rocket as early as April, according to NASA.

Starliner

Boeing’s commercial spacecraft shares similarities with SpaceX’s Crew Dragon: it can seat a crew of seven, be operated from a central control panel, dock autonomously with the ISS, and can also be reused multiple times.

Boeing’s Starliner is the result of a $4.2 billion contract signed with NASA in 2014 under the Commercial Crew Program. SpaceX signed a very similar contract for its Crew Dragon mission at the same time, although it paid SpaceX just $2.4 billion.

Race to the ISS

SpaceX successfully launched its passenger spacecraft to the ISS on Saturday, becoming the first ever private American spacecraft to do so. It also marked the first time astronauts launched into space from American soil since the end of NASA’s Space Shuttle program in 2011.

Boeing has tests to complete before it takes off.

“There still are many critical steps to complete before launch and while we eagerly are anticipating these launches, we will step through our test flight preparations and readiness reviews,” Kathy Lueders, Commercial Crew Program manager at NASA said in an official update.

SpaceX is planning a crewed test flight in July of this year. Boeing wants to do the same only a month later — and its first pilots are already on stand-by.

China: New “Artificial Sun” Will Be Completed This Year

A Chinese official claims the nation is poised to wrap up construction on the HL-2M tokamak, a new

On the Horizon

In November, Chinese researchers announced that the Experimental Advanced Superconducting Tokamak (EAST) reactor — an “artificial sun” designed to mimic the nuclear fusion process the real Sun uses to generate energy — had hit a milestone by achieving an electron temperature of 100 million degrees Celsius.

Now, officials are saying they believe they’ll wrap up construction on a new artificial sun this year, and they claim this device will be able to hit a milestone in ion temperature — putting us one step closer to harnessing the power of nuclear fusion.

Hot Tech

On Sunday Duan Xuru, an official at the China National Nuclear Corporation, announced during the annual session of the Chinese People’s Political Consultative Conference that engineers would wrap up construction on the nation’s HL-2M Tokamak in 2019.

“The artificial sun’s plasma is mainly composed of electrons and ions,” Duan told the media, according to the Global Times, “and the country’s existing Tokamak devices have achieved an electron temperature of over 100 million degrees C in its core plasma, and an ion temperature of 50 million C, and it is the ion that generates energy in the device.”

Tokamak

According to Duan, the HL-2M Tokamak will be able to achieve an ion temperature of 100 million degrees Celsius, about seven times hotter than the real Sun’s ion temperature. This meets meeting what the Global Times calls “one of the three challenges to reach the goal of harnessing the nuclear fusion.”

If he’s right, the device could serve as a template for future nuclear fusion reactors, bringing the dream of unlimited clean energy one step closer to reality.

NASA Is About to Test a Giant Solar Drone That Broadcasts 5G

The Hawk 30

Japanese tech giant SoftBank partnered with NASA and U.S. aerospace company AeroVironment to build a massive solar-powered drone that can beam 5G connectivity down to practically anywhere in the world.

A maiden voyage of SoftBank’s Hawk 30 prototype could take place as soon as next week, according to a November Space Act Agreement with NASA. More test flights will follow within the next three months — an initiative that if successful could bring wireless connectivity to the most remote regions of the globe.

Remote Areas

The Hawk 30 is an unmanned aerial vehicle (UAV) that features ten electric engines and can fly at altitudes of over 65,600 feet (20 km) according to IEEE Spectrum. Other than that, details are sparse.

The Hawk 30 won’t be the first UAV of its kind to attempt to bring connectivity to remote areas. The drone that holds the record of any winged horizontal aircraft was set by AeroVironment’s previous prototype, the Helios. That prototype was “an elegant flying wing wider than a 747 but weighing less than just one of the jumbo jet’s 18 landing wheels,” IEEE Spectrum writes.

It flew at an altitude of 93,000 feet back in 2001, but splintered into tiny pieces and fell into the Pacific Ocean just two years later due to turbulence.

Facebook and Google

Facebook also jumped on the bandwagon with its Aquila solar-powered drone. The Aquila project was an experiment to see if it was possible to bring internet connectivity to remote areas as well. A prototype stayed aloft for almost two hours over the Arizona desert in June 2017 during its second test flight. But the project was grounded in June 2018.

Even Google tried its hand, testing its SkyBender system in 2016. High-altitude balloons made more sense to the company in the end — the project was replaced by Alphabet’s Loon project in 2017.

It’s a concept with a poor track record so far. But that’s not stopping companies from learning from their mistakes and trying again.

NASA Announces World’s First All-Female Spacewalk

On March 29, NASA astronauts Anne McClain and Christina Koch will leave the ISS to embark on the world's first all-female spacewalk.

The Female Frontier

Two of NASA’s astronauts are scheduled to make history this month.

On March 29, Anne McClain and Christina Koch will leave the relative safety of the International Space Station for a spacewalk to upgrade the craft’s batteries.

Though rare, a spacewalk alone isn’t history-making. What’s exciting is the fact that this spacewalk will be the first to feature only women astronauts — an inspiring sign that women are catching up with men in exploring the final frontier.

Spacewalk This Way

On Wednesday, NASA spokeswoman Stephanie Schierholz confirmed the all-female spacewalk with CNN.

“As currently scheduled, the March 29 spacewalk will be the first with only women,” she told the network.

In addition to McClain and Koch, Schierholz pointed out that two other women will play important roles behind the scenes for this spacewalk — Mary Lawrence and Jackie Kagey will serve as the spacewalk’s lead flight director and lead spacewalk flight controller, respectively.

A third woman, Canadian Space Agency flight controller Kristen Facciol, will support the spacewalk from NASA’s Johnson Space Center in Houston. She’s the one who first broke the news of the all-female spacewalk with an exuberant tweet on March 1.

I just found out that I’ll be on console providing support for the FIRST ALL FEMALE SPACEWALK with @AstroAnnimal and @Astro_Christina and I can not contain my excitement!!!! #WomenInSTEM #WomenInEngineering #WomenInSpace

— Kristen Facciol (@kfacciol) March 1, 2019

As with anything space-related, there is always a chance the spacewalk might not go as planned, with Schierholz telling CNN that “assignments and schedules could always change.”

Still, right now, it’s looking like McClain and Koch will spacewalk their way into the history books on March 29.

Stalkers Are Pretending to be Cops to Steal Your Phone’s Location

By telling companies such as Verizon and T-Mobile they're cops, stalkers and scammers can get users' real-time location data.

Just Ask

A loophole designed to protect lives is actually endangering them.

While cell phone companies typically require a court order before they’ll give law enforcement officials a customer’s real-time location data, they will make exceptions under “exigent circumstances” — for example, if turning over the data might prevent someone from being harmed.

Now, Motherboard is reporting that phone companies are also turning over this data to people impersonating officials — another troubling example of how little tech companies are doing to protect your personal data.

Scam Alert

According to Motherboard’s sources — which included Valerie McGilvrey, a skip tracer hired to find people’s locations — Verizon, T-Mobile, and Sprint have all turned over real-time location data to scammers who claimed to be law enforcement officials.

In some instances, the scammers were bounty hunters or debt collectors. In others, they were stalkers and domestic abusers trying to track down their victims. The stories they spin vary, but fake child kidnappings seem to be common approach.

“So many people are doing that and the telcos have been very stupid about it,” McGilvrey told Motherboard. “They have not done due diligence and called the police [departments] directly to verify the case or vet the identity of the person calling.”

Unprotected

This is far from the first example of tech companies inadequately protecting user data — from Facebook to Google, we constantly hear about companies experiencing data breaches, with users’ personal data ending up in the hands of people who were never meant to have access to it.

The issue has now gotten to the point that some legislators are suggesting bills to jail the execs of companies that don’t adequately protect user data — and if there’s one thing more worthy of punishment than accidentally leaking personal data, it might be willingly handing it over like these telephones companies are doing.

SpaceX’s Crew Dragon Spacecraft Splashes Down in the Atlantic

Welcome Home

Mission Demo-1 is officially complete.

After successfully undocking from the International Space Station in the early morning hours and burning through Earth’s atmosphere, SpaceX’s passenger spacecraft slowly descended back down to Earth, before safely splashing down into the Atlantic Ocean — and right on schedule at 8:45 am EST.

.@SpaceX’s #CrewDragon returned to Earth with a splash in the Atlantic Ocean off Florida’s eastern shore at 8:45am ET, completing an end-to-end flight test to the @Space_Station and back as part of our @Commercial_Crew Program. Learn more: https://t.co/MFB7dVb60c pic.twitter.com/8lFL6X3Tue

— NASA (@NASA) March 8, 2019

The Descent

Crew Dragon’s descent was slowed thanks to four large parachutes it deployed once it re-entered Earth’s atmosphere.

Astronauts loaded roughly 300 pounds (136 kg) of cargo from the ISS into the spacecraft on Thursday to send back down to Earth.

SpaceX successfully launched the spacecraft on Saturday. It marks the first time a passenger spacecraft launched from American soil to the ISS — and returned safely back down to Earth — since the end of NASA’s Space Shuttle program in 2011.

Mission Accomplished

SpaceX’s Crew Dragon docked itself, with no robotic arm required, to an open port of the International Space Station early Sunday morning. It then spent five days docked to the station while astronauts checked out the inside of what could one day become their ride back home.

A lot could’ve gone wrong. The cargo Dragon variant featured a different parachute system and had a differently shaped hull.

“I see hypersonic re-entry as probably my greatest concern,” SpaceX CEO Elon Musk said during a post-launch press event on Saturday.

In July, SpaceX is hoping to send the Crew Dragon capsule back into space — but this time with NASA astronauts Bob Behnken and Doug Hurley on board.

Elizabeth Warren Shares Plan to Break up Facebook, Google, Amazon

Senator and presidential candidate Elizabeth Warren announced a bold plan today to break up tech giants Amazon, Facebook, and Google.

Breaking Up

Senator and presidential candidate Elizabeth Warren announced a bold plan on Friday to break up tech giants Amazon, Facebook, and Google.

“Today’s big tech companies have too much power — too much power over our economy, our society, and our democracy. They’ve bulldozed competition, used our private information for profit, and tilted the playing field against everyone else,” Warren wrote in a Medium post about the plan. “That’s why my Administration will make big, structural changes to the tech sector to promote more competition — including breaking up Amazon, Facebook, and Google.”

Baby Bells

In particular, Warren singled out “anti-competitive mergers,” such as Amazon’s ownership of Whole Foods and Zappos, Facebook’s WhatsApp and Instagram, and Google’s Waze, Nest, and DoubleClick.

“Unwinding these mergers will promote healthy competition in the market? — ?which will put pressure on big tech companies to be more responsive to user concerns, including about privacy,” Warren wrote in the post.

It’s not unprecedented for the U.S. government to break up large enterprises. In the 1980s, it divided the American Telephone and Telegraph Company into so-called “Baby Bells” — several of which later re-merged into Verizon.

Zuckerberg Beware

Warren also alluded to how huge tech interests have upset the balance in the marketplace of ideas, noting how state actors may have used Facebook and other platforms to try to influence the U.S. presidential election in 2016.

“We must help America’s content creators — from local newspapers and national magazines to comedians and musicians — keep more of the value their content generates, rather than seeing it scooped up by companies like Google and Facebook,” Warren wrote on Medium. “And we must ensure that Russia — or any other foreign power — can’t use Facebook or any other form of social media to influence our elections.”

New Zealand Farmers Are Using Drones to Herd Sheep

Farmers in New Zealand have a new tool to herd sheep and cows, according to Radio New Zealand: drones outfitted with speakers so they can bark like dogs.

Sheep Drones

Farmers in New Zealand have a new tool to herd sheep and cows, according to Radio New Zealand: drones outfitted with speakers that blast the sounds of dogs barking.

“That’s the one thing I’ve noticed when you’re moving cows and calves that the old cows stand up to the dogs, but with the drones, they’ve never done that,” shepherd Corey Lambeth told the station.

Radio New Zealand video shows Lambeth corralling cows and sheep using a drone with a harsh digital bark.

Dog Days

Lambeth’s employer, Ben Crossley, confirmed that his fourth-generation farm is indeed using drones to control sheep. One favored model: the DJI Mavic Enterprise, which is already outfitted to play sounds — such as barking — over a speaker.

The Washington Post noted that farmers are already using drones around the world for a variety of farming tasks, *including* surveying crops.

The Washington Post noted that farmers are already using drones around the world for a variety of farming tasks, including surveying crops. Having the devices deal directly with animals is less common — but it could be a vision of the future of agriculture.

Drone Pups

Dogs, which were already used for herding in New Zealand, are learning to work alongside the drones, according to another story by Radio New Zealand.

“There’s definitely going to be places for dogs always on farm,” Lambeth told the station, but “the one downside of the Mavic [drones] or anything electronic is you still need to bring them in and charge them.”

Psychedelic Mushrooms Can Boost Creativity and Empathy for a Week

The positive benefits of ingesting psilocybin, the active ingredient in psychedelic mushrooms, can last for up to a week, according to a new study.

Magic Medicine

The benefits of taking psychedelics could last long after the trip ends.

A team of Dutch researchers has found that psilocybin, the active ingredient in psychedelic mushrooms, doesn’t just increase a person’s creativity, empathy, and feeling of well-being while a user trips. It also allows them to experience all of those benefits for up to seven days — providing valuable insight into how we could tap into the therapeutic value of hallucinogenics.

Tea Time

For their study, which was recently published in the Journal of Psychoactive Drugs, the team from Maastricht University recruited 55 attendees of a retreat of the Psychedelic Society in the Netherlands.

They asked the subjects, about half of whom hadn’t taken psilocybin before, to complete a series of tests designed to measure their creativity, empathy, and general satisfaction with life three times: once the evening before ingesting a tea made from psychedelic mushrooms, once the morning after drinking it, and then finally seven days later.

“We found that psilocybin, when taken in a naturalistic setting, increased aspects of creativity and empathy the morning after, and 7 days after use,” researcher Natasha Mason told PsyPost. “Furthermore, psilocybin also enhanced subjective well-being.”

Window of Opportunity

As Mason admitted to PsyPost, the study did have several limitations, including the lack of a control group and the fact that the participants were all people who chose to attend a psychedelic retreat.

However, she still believes the team’s study produced valuable insights into the potential therapeutic benefits of psychedelics.

“These findings are important in trying to understand psychedelics’ therapeutic utility in the treatment of certain pathologies,” Mason told PsyPost. “Specifically, in a therapy session, enhancements in empathy could increase feelings of openness and trust between patient and therapist, thus strengthening the therapeutic alliance.”

“Furthermore, enhancements in flexible, creative thinking could allow individuals to break out of their old patterns of thought, and generate new and effective cognitive, emotional, and behavioral strategies,” she continued. “Importantly, our data suggest that these effects outlast the acute phase and persist over time, thus potentially opening up a ‘window of opportunity’ where therapeutic interventions could prove more effective.”

Police Arrest Vandal Who Trashed Tesla Supercharger

Supercharger Vandalism

First, pickup truck owners started taking over Supercharger stations in apparent protest. Now a vandal has struck one of Tesla’s electric vehicles chargers.

Last week, a 52 year-old man physically vandalized the charging cable and ports at all the docks of a local St. George, Utah’s Tesla Supercharger station, local news reports — the latest skirmish in a simmering culture war about electric vehicles.

Confession

It took local law enforcement less than 24 hours from the start of their investigation to find a suspect named Johnny Doak. According to St. George News, he had been drinking heavily that night and was “grieving the death of a family member.”

Doak later confessed to his crime. Whether it was his intention was to vandalize a Tesla Supercharger station in particular is unclear. Police estimate total repair costs to be $8,000.

ICEing

The news comes after pickup drivers in the U.S. were found to park their trucks in unoccupied Tesla Supercharger spots. The trend became known as “ICEing,” due to the symbolic weight of vehicles with internal combustion engines (ICE) blocking access to electric vehicle charging stations.

Tesla developed a clever solution to the problem earlier this year by installing metal hurdles that could be lowered using a QR code on the Tesla owner’s phone.

It’s an ominous trend, but incidents have thus far been uncommon. But it goes to show that not everybody is happy about the spread of electric cars — for whatever reason.

Watch a 3D Printed Self-Driving Shuttle Smash Into a Wall

Local Motors demonstrates how its Olli self-driving shuttle reacts during crash testing in a pair of video shared exclusively with The Verge.

Olli-Oops

Typically, the last thing an automaker wants the media to present is graphic video of its vehicles crashing. Not so with Local Motors.

The Arizona-based startup reached out to The Verge with exclusive video of its 3D-printed self-driving shuttle Olli in what CEO Jay Rogers calls its “worst-case scenario”: smashing into a wall at 40 kilometers per hour (25 miles per hour).

“What I hope we’re showing, by showing people these vehicles crashing, is that we’re doing the due diligence,” Rogers told the outlet. “We want people to see the progress.”

Grand Slam

The video of the crash test, which was recorded in late 2018, is quite spectacular, with plenty of flying glass and buckled wheels.

“It was quite an experience,” Rogers told The Verge. “It’s kind of the first time I think anyone has really done any kind of large-scale crash testing with a 3D-printed vehicle, so it was pretty amazing to be part of that project and kind of be on the cutting edge of that pushing the science forward.”

Still, once the wreckage settles, it’s clear that the structure of the self-driving shuttle has remained largely intact. In another video shared with The Verge, Olli doesn’t appear to sustain any damage at all — though in that one, it’s only moving at 4.8 kph (3 mph).

Fine Print

Local Motors is already testing Olli on public roads, where it operates at speeds that roughly split the difference of the two crash videos: 24 to 29 kph (15 to 18 mph).

According to Rogers, the fact that the vehicle is 3D printed tends to be a point of concern for potential passengers. But it’s the 3D printing that allows Local Motors to easily tweak Olli’s design to improve safety or incorporate the latest technology, he said.

“Many people just ask the question, ‘Well, is it safe or not? Like, am I riding around in something that a MakerBot printed?'” Rogers told The Verge, name checking a prominent brand of consumer-oriented 3D printer. “The answer is, not only is it as safe, but it will be safer in the future.”

Mitsubishi’s New Hybrid Can Power Your Home During a Blackout

Bi-Directional Charging

In the future, your car will charge your house.

That’s according to Japanese carmaker Mitsubishi, which is working on a solar platform — including a sizable home battery, charger and solar panels — called Dendo Drive House. The twist: it can use the company’s lineup of plug-in hybrid cars to store extra power.

It’s a futuristic concept: when the sun shines, both your car and home charge up at the same time thanks to a “bi-directional charger.” If you’re stuck with no power from the electric grid, your home is able to use up your plug-in hybrid car’s remaining battery reserves.

In its promotional video, Mitsubishi argues it might even save you some money — you can chose to charge your home from the grid at night, when electricity prices are lower.

The Engelberg Tourer

The reveal came alongside the announcement of Mitsubishi’s Engelberg Tourer, a “next-generation crossover SUV concept” at this year’s Geneva Motor Show.

The Tourer is meant to skip the need for charging infrastructure altogether, according to the press release, thanks to its generous battery pack — and of course the Dendo Drive House platform with its bi-directional charging capability.

It’s not the first time the idea has cropped up: Tesla CEO Elon Musk mentioned the idea in a July 2018 tweet, pointing out it might make sense for his electric vehicle company to “revisit” the idea.

Like many concepts of its kind, there’s no guarantee Mitsubishi’s SUV and the Dendo Drive House platform will ever be released to the public.

While Tesla has already shown the benefits of mounting a massive home battery packs to your garage wall, the efficiency of home solar panel technology still has a way to go.

But who wouldn’t want to save some money on their energy bills while ensuring that their energy demands are met even during a power outage?

Robbers Tortured a Man With a Drill to Steal His Cryptocurrency

Home invaders tortured a crypto trader with an electric to force him to give up his cryptocurrency, according to a Dutch newspaper.

Crypto Crime

A key promise of the digital cash known as cryptocurrency is its security — because only you possess the password to access your money, it’s presumably more safe than it would be at a bank.

But a grisly crime in the Netherlands — in which home invaders tortured a crypto trader in an attempt to force him to give up his coins — shows that there’s also a dark side to having total control over your own wealth.

Robber Squad

According to the Dutch newspaper De Telegraaf, a trio of robbers disguised as police burst into the home of an unidentified cryptocurrency trader in late February.

Then, in view of the man’s four-year-old daughter, they tortured the crypto trader with an electric drill — causing injuries so severe that he was hospitalized for five days, according to a follow-up story.

It’s not clear whether they obtained any of the crypto trader’s funds before leaving, but if he did turn over his password, the criminals could have transferred the money to an anonymous account almost instantly.

Followup

Dutch police were horrified by the crime, according to De Telegraaf, and dispatched 15 officers to investigate. The cops refused to comment, but police sources confirmed to the newspaper that the criminals were after the man’s cryptocurrency holdings.

Crypto news site CoinTelegraph pointed out that there have been other examples of violent criminals attempting to steal cryptocurrency, such as a Russian businessman who was held hostage until he surrendered his Bitcoin funds.

“If you are rich and you own real estate, or stocks or a sports team, somebody can’t mug you and take your sports team away,” Bitcoin engineer Jameson Lopp told The New York Times in 2018. “Having liquid crypto assets makes you much more attractive for that type of criminal attack.”

NASA engineers have captured the first images of the interaction between shockwaves from a pair of flying supersonic aircraft — and they are stunning.

Supersonic Flight

NASA engineers have captured the first images of the interaction between shockwaves from a pair of flying supersonic aircraft — and they are stunning.

“We’re seeing a level of physical detail here that I don’t think anybody has ever seen before,” senior research engineer Dan Banks said in a NASA press release. “Just looking at the data for the first time, I think things worked out better than we’d imagined.”

“We never dreamt that it would be this clear, this beautiful,” physical scientist J.T. Heineck added.

Making Waves

When an object moves faster than the speed of sound, it causes rapid air pressure changes called shockwaves.

To record the interaction between shockwaves from two craft, NASA had two T-38 jets from the U.S. Air Force Test Pilot School at Edwards Air Force Base fly at supersonic speeds, with one jet about 30 feet behind and 10 feet below the other.

NASA then flew a B-200 King Air aircraft in a holding pattern at an altitude of approximately 30,000 feet. Using a special recording system, including a camera capable of recording 1,400 frames per second, the team then captured footage of the two T-38s as they passed about 2,000 feet below the B-200 at supersonic speeds.

“The biggest challenge was trying to get the timing correct to make sure we could get these images,” sub-project manager Heather Maliska said. “I’m absolutely happy with how the team was able to pull this off… They were rock stars.”

Sounds Great

When shockwaves merge, they produce sonic booms, loud noises that are one of the reasons supersonic flight is currently restricted over land. NASA is developing a craft called the X-59 Quiet SuperSonic Technology X-plane that’s designed to fly at supersonic speeds without producing any sonic booms — just a quiet rumble.

However, if NASA hopes to convince regulators to change existing restrictions on supersonic flight over land — and enable travelers to get from one part of the U.S. to the other far more quickly —  they’ll need to be able to produce highly detailed, statistically sound images of the upcoming X-59 demonstrations.

And now, the agency knows it has an imaging system capable of producing those photos.

“I am ecstatic about how these images turned out,” Heineck said in the news release. “With this upgraded system, we have, by an order of magnitude, improved both the speed and quality of our imagery from previous research.”
