Definition of Nanotechnology:

Nanotechnology is the understanding and control of matter at the realm of 1 to 100 nanometers. (For reference, a piece of paper is about 100,000 nanometers thick.) At the nanoscale, matter functions differently from both the individual atomic and macroscopic scales, so some unique properties are available for use in the field.

Development of Nanotechnology:

Nanotechnology is a natural end-result of scientific development and our ability to understand and manipulate matter at smaller and smaller levels.

Just as computers have gone from bulky, room-filling monstrosities to handheld computers, such reductions in size will continue until we reach fundamental physical limits.

Feynman & Nanotechnology:

On December 29, 1959, the influential American physicist Richard P. Feynman presented a talk to the American Physical Society entitled “There’s Plenty of Room at the Bottom: An Invitation to Enter a New Field of Physics.” Among physicists, this is respectfully called “the classic talk” (it’s the first hit on a Google search of “classic talk”). He asked “Why cannot we write the entire 24 volumes of the Encyclopedia Brittanica on the head of a pin?” and introduced the concept of nanotechnology.

Spread of Nanotechnology:

Though Feynman’s speech inspired many researchers, it wasn’t until the mid-1980s that nanotechnology began to seep into the cultural mainstream conversation. In 1986, the MIT researcher K. Eric Drexler wrote Engines of Creation which laid out extensive prospects of emerging nanotechnology research.

Nanotechnology & Medicine:

One major application of nanotechnology is in the field of medicine, and in fact the knowledge gained from research of natural nanomachines, such as bacteria, has proven essential to the field.

In this respect, it has developed some close connections with biophysics. It is theorized that man-made nanomachines could repair damage to the human body that is currently untreatable.

Graphene:

One material which is frequently discussed in nanotechnological research is graphene, an atom-thick form of graphite which was discovered by a University of Manchester team in 2004.

Preparing for a Career in Nanotechnology:

There are few degrees of study specifically in nanotechnology, so look for a good, well-rounded physics program. Nanotechnology works at tiny levels of matter, so knowledge of atomic, molecular, chemical and quantum physics is essential to this field of study.

Working knowledge of biochemistry, chemistry, and biophysics, as well as a proficiency with complex mathematics, would also help qualify you for this field.

More than 70,000 people attended event

NASHVILLE (CNN) –

A pack of 2016 Republicans made their pitch for president Friday before the National Rifle Association’s annual meeting in Nashville, blasting the Obama administration for what they described as an erosion of freedom while punctuating their remarks with sharp enthusiasm for Second Amendment rights.

The contenders also used the principles behind gun rights to fire off criticism of President Barack Obama’s handling of national security, further signaling the influential role that foreign policy is expected to have in the presidential election.

More than 70,000 people descended upon Music City to attend the convention, but tickets to see the candidates speak in a five-hour long forum was limited to about 5,000 people.

Sen. Ted Cruz of Texas was the only declared candidate on stage Friday. Other potential contenders included former Florida Gov. Jeb Bush, former Sen. Rick Santorum of Pennsylvania, former Texas Gov. Rick Perry, Wisconsin Gov. Scott Walker, Louisiana Gov. Bobby Jindal, former Arkansas Gov. Mike Huckabee, retired neurosurgeon Ben Carson, former Hewlett-Packard CEO Carly Fiorina and Sen. Lindsey Graham of South Carolina.

1. Candidates show off gun credentials

As tradition at the annual NRA gathering, the speakers tried to establish their own longstanding history with guns in different ways. Santorum held up his concealed carry card before the audience and boasted that his wife requested ammunition for an upcoming birthday.

Walker talked about bow-hunting, while Huckabee perused the firearm vendor hall and later listed on stage the guns he grew up with, including his first BB gun at the age of five. “I still have the same gun in mint condition,” he said.

Perry screened a video showing off his shooting skills (the same video was also shown at the 2013 NRA convention). The former governor also crowed about the gun manufacturers he recruited to Texas from other states.

For Bush, the NRA meeting was a chance to tout his record, including his A+ rating from the NRA, before a conservative crowd that’s largely skeptical of him due to his more moderate positions on immigration and Common Core.

Bitcoin keeps falling Wednesday

The exchange ultimately resumed services after admitting that about $5 million worth of bitcoins had been stolen. O’Connor said the development may have spooked some cryptocurrency speculators, as Bitstamp had a reputation as one of the more professional outfits in the bitcoin community.

“I would imagine they were inundated with requests for withdrawal on Friday,” he said.

Read MoreBitcoin breaks another key level

Another factor weighing on the cryptocurrency is that Russia is beginning to ban bitcoin-related websites, “Fast Money” trader Brian Kelly pointed out in a blog post.

Still, the selling that continued into Wednesday may also be part of a vicious cycle, as some have theorized on the influential Reddit bitcoin forum. In other words, the low prices may be forcing volunteers who “mine” new bitcoins to cut their losses. If the price falls below the electricity and hardware costs of “mining” bitcoinsa process that involves solving highly complex mathematical algorithmsthen the enterprise becomes unprofitable, and some miners will be forced to sell their holdings and give up.

That said, bitcoin’s death has been predicted many times (one site has counted 29 obituaries), and some predict that the technology behind the system could live well beyond the currency it now supports.

Kaiser seen as a model for health care overhaul

Sharon Brandon, 59, watched her cousin and her auntie die in a matter of months. Her beloved mother went in two weeks. Big Mama, the grandmother who famously distrusted doctors, lasted four months.

Cancer, too far gone to halt, took them all.

Were it not for a persistent Kaiser Permanente doctor badgering her to get her annual mammogram, Brandon might have suffered the same fate. Turns out, the screening captured the image of a tiny white mass of 1.2 centimeters: Stage 1 breast cancer.

“I feel very blessed that the doctors caught it early,” said Brandon, an Elk Grove teacher’s aide who underwent surgery. She is getting radiation and reports feeling well.

Brandon’s case exemplifies the Kaiser experience, experts say. That focus on prevention is what has helped Kaiser evolve from an HMO with a reputation for cut-rate, cookie-cutter care to the health care industry giant it is today.

In the four decades since President Richard Nixon officially threw the federal government’s weight behind the concept of HMOs, Kaiser has shed its early growing pains and stigma, rising to become a national model for health care reform.

Today, Kaiser reports that it commands 43 percent of the privately paid insurance commercial market in Sacramento, more than any other health care insurer. In the greater Sacramento four-county region, Kaiser claims 30 percent of the market.

Kaiser operates 35 hospitals and boasts 5.5 million Californians as its commercial customers, collecting $23.3 billion in premiums annually, according to a Citi Investment Research analysis. That analysis concluded that the nonprofit company has captured 40 percent of the state’s commercial and individual markets, more than any competitor.

Kaiser’s upward trajectory is timely, coming as the Affordable Care Act stands poised to overhaul federal health care so that the industry, in effect, mirrors Kaiser’s model of emphasizing prevention, wellness, integrated care and use of electronic medical records. Kaiser’s top executive was among the influential players at the table in Washington, D.C., as the policies that would underpin the ACA were shaped.

California officials also have cited the Kaiser model as they move to carry out the federal health care overhaul here. The Legislature recently selected Kaiser as a model for other insurers to follow when they offer products through the state’s health exchange.

Beauty Innovation: Young-looking skin with stem cell therapy

Admit it or not, as you age your skin starts showing signs that you would rather hide. Spots, wrinkles, and even crow’s feet are just some of those signs that you would camouflage with makeup and skin creams to make them disappear-temporarily. But fear not, for beauty experts have discovered that stem cell treatment can also help in maintaining youthful skin.

According to Ma Fe Doria, a skin care expert, stem cell therapy is an intervention strategy that introduces new adult stem cells into damaged tissue in order to treat disease or injury. As many may be aware, the most popular stem cell treatment is in Germany, where lots of celebrities and personalities (i.e. politicians) have flown to have stem cell injections for their ailments, using cells mostly harvested from the sheep. According to those who have undergone the procedure, the treatments have improved their body and the pains they’ve experienced have disappeared.

Today, many medical researchers continue to do experiments to determine if stem cell can help in curing various types of ailments from cancer to diabetes, which doctors have said may not be far behind. Aside from its healing benefits, stem cell is now being used by the beauty industry. Many cosmetic and beauty centers have started offering stem cell injections for the face, which is said to regenerate the skin where the cells are injected. While some continue to use sheep cells, plant and fat stem cells are now becoming the popular alternatives, with the fat stem cells being used to heal wounds, improve scars, and rejuvenate the skin.

But stem cell treatment is not cheap. Those who can afford it need to fly out of the country to avail of the treatment. Realizing the need in the market, Flawless Facial Center partnered with a local industry leader to produce Flawless’ Stem Cell line, which uses the potent power of plant stem cells. Dubbed as the “superfood for the skin,” Flawless’ Stem Cell line is the epitome of skin nutrition.

“This new range of products allowed us to mark several milestones not just for Flawless but for the local beauty industry. Once again, we have taken something that, for the longest time, has remained exclusive to celebrities and other influential people, and made it affordable for the regular Juan and Juana,” says Flawless ceo Ruby Sy.

For P2,500, the line includes a cleanser, day cream, and night serum. Flawless’ Stem Cell line utilizes the plant stem cell technology to achieve the skin’s youthful appearance by protecting it against oxidative stress and boosting the skin’s repair and rejuvenation systems. “Times have really changed. No thanks to free radicals that are present in almost everything around us-from the food we eat to the air we breathe-people today age so much faster. This is especially true for people who like to spend late nights partying or spend too much time in front of the [TV/computer] monitor. Various studies have proven time and again the harmful effects such activities have on our skin,” Sy said.

But with Flawless’ latest baby, you can say goodbye to those ugly marks on your face. The Stem Cell line promises to solve all these, and more, by providing your skin with the right amount of nutrition and protection. Indeed, youthful glow is not only safe and available in a bottle, it’s also now within reach of your pocket.

Report: US health care system wastes $750B a year – Boston.com

WASHINGTON (AP) The U.S. health care system squanders $750 billion a year roughly 30 cents of every medical dollar through unneeded care, byzantine paperwork, fraud and other waste, the influential Institute of Medicine said Thursday in a report that ties directly into the presidential campaign.

President Barack Obama and Republican Mitt Romney are accusing each other of trying to slash Medicare and put seniors at risk. But the counter-intuitive finding from the report is that deep cuts are possible without rationing, and a leaner system may even produce better quality.

Health care in America presents a fundamental paradox, said the report from an 18-member panel of prominent experts, including doctors, business people, and public officials. The past 50 years have seen an explosion in biomedical knowledge, dramatic innovation in therapies and surgical procedures, and management of conditions that previously were fatal …

Yet, American health care is falling short on basic dimensions of quality, outcomes, costs and equity, the report concluded.

If banking worked like health care, ATM transactions would take days, the report said. If home building were like health care, carpenters, electricians and plumbers would work from different blueprints and hardly talk to each other. If shopping were like health care, prices would not be posted and could vary widely within the same store, depending on who was paying.

If airline travel were like health care, individual pilots would be free to design their own preflight safety checks or not perform one at all.

How much is $750 billion? The one-year estimate of health care waste is equal to more than ten years of Medicare cuts in Obamas health care law. Its more than the Pentagon budget. Its more than enough to care for the uninsured.

Getting health care costs better controlled is one of the keys to reducing the deficit, the biggest domestic challenge facing the next president. The report did not lay out a policy prescription for Medicare and Medicaid but suggested theres plenty of room for lawmakers to find a path.

Both Obama and Romney agree there has to be a limit to Medicare spending, but they differ on how to get that done. Obama would rely on a powerful board to cut payments to service providers, while gradually changing how hospitals and doctors are paid to reward results instead of volume. Romney would limit the amount of money future retirees can get from the government for medical insurance, relying on the private market to find an efficient solution. Each accuses of the other of jeopardizing the well-being of seniors.

But panel members urged a frank discussion with the public about the value Americans are getting for their health care dollars. As a model, they cited Choosing Wisely, a campaign launched earlier this year by nine medical societies to challenge the widespread perception that more care is better.

Aerospace Futures Alliance endorses McKenna

Washington Attorney General Rob McKenna has earned the endorsement of one of the state’s most influential aerospace groups.

On Thursday, the Aerospace Futures Alliance announced its first-ever endorsement of a political candidate, embracing Republican McKenna’s bid for governor. An industry interest group, AFA lobbies on behalf of the state’s 720 aerospace-related companies. Its board consists of representatives from Boeing, state community colleges, Mukilteo aerospace supplier Electroimpact, Everett maintenance company Aviation Technical Services and other government and commerce groups.

The success of AFA’s member companies has meant tens of thousands of family wage jobs for our state,” McKenna said in a statement. “I will help this industry remain globally competitive long into the future.

AFA previously has contributed to at least two candidates’ campaigns: $900 to House Speaker Frank Chopp and $1,600 to Gov. Chris Gregoire’s 2008 campaign.

Another influential group in the industry, the local District 751 of the International Association of Machinists and Aerospace Workers, already has given its endorsement to McKenna’s opponent, Democrat Jay Inslee. The local IAM represents nearly 30,000 Machinists who work for Boeing in the Puget Sound region.

In interviews with the Herald published in March, both candidates identified the need to maintain a steady pipeline of aerospace workers as the main challenge facing the industry in the state.

Boeing and its suppliers are increasing jet production rates. The company also faces a many retirements in the coming years, both Machinists and engineers. As a result, Boeing has upped hiring in Washington, adding 2,850 workers through the end of June. Company officials have said employment will level out this year but hiring to replace workers who retire still will require Boeing to hire thousands of workers.

Japan considers buying disputed islands

Japan is considering buying a chain of islands at the centre of a bitter territorial dispute with China and Taiwan, Prime Minister Yoshihiko Noda says.

THE move could potentially reignite tensions with both Beijing and Taipei, which also claim the islands in the East China Sea, called Senkaku in Japanese and Diaoyu in Chinese.

“There is no question that the Senkakus are an integral part of our country’s territory in terms of history and international law,” Noda told reporters on Saturday.

“There exists no territorial issue or ownership issue as Japan is in effective control of the islands.

“From the viewpoint of how to maintain and manage the Senkakus in a calm and stable manner, we are making comprehensive studies on the matter by keeping in touch with the owner.”

The prime minister’s comments came after a report in the influential Asahi Shimbun newspaper said the government on Friday had informed Tokyo’s governor, Shintaro Ishihara, of its plan to buy three of the islands from their private Japanese owner.

In April, Ishihara announced he was in talks to buy the three islands – Uotsurijima, Kitakojima and Minamikojima – claiming that Japan was not doing enough to protect the territory.

The chain includes two other islands and an outcropping of rocks.

The Asahi Shimbun reported that senior government officials were already negotiating with the owner, the Kurihara family, hoping to finalise the nationalisation plan by the end of the year.
