VIDEO: Action Cam Footage From U.S. Spacewalk On International … – SpaceCoastDaily.com
Posted: May 9, 2017 at 3:04 pm

(NASA) This footage was taken by ESA astronaut Thomas Pesquet during a spacewalk on the International Space Station on Friday, March 24.
He was joined on the spacewalk by NASA astronaut Shane Kimbrough.
The primary task was to prepare the Pressurized Mating Adapter-3 (PMA-3) for installation of the second International Docking Adapter, which will accommodate commercial crew vehicle dockings.
The PMA-3 provides the pressurized interface between the station modules and the docking adapter.
The pair disconnected cables and electrical connections on PMA-3 to prepare for its robotic move, which took place on Sunday, March 26. PMA-3 was be moved from the port side of the Tranquility module to the space-facing side of the Harmony module, where it will become home for the docking adapter, which will be delivered on a future flight of a SpaceX Dragon cargo spacecraft.
The spacewalkers also installed on the starboard zero truss a new computer relay box equipped with advanced software for the adapter.
The two spacewalkers lubricated the latching end effector on the Special Purpose Dexterous Manipulator extension for the Canadarm2 robotic arm, inspected a radiator valve suspected of a small ammonia leak and replaced cameras on the Japanese segment of the outpost.
Radiators are used to shed excess heat that builds up through normal space station operation.

The Flaming Lips’ Onboard The International Space Station Concert … – Consequence of Sound (blog)
Posted: at 3:04 pm
Photo by Philip Cosores
For Record Store Day this year, The Flaming Lips releasedOnboard The International Space Station Concert For Peace, a release they described as featuringseven live(ish) tracks from Oczy Mlody reimagined as a fictional/fantastical live Flaming Lips performance on the International Space Station. The release was limited to just 2,700 copies, so its very likely you werent able to get your mitts on one.
Well, heres some consolation: The album is now available to stream on Apple Music and Spotify. Its a trippy listen, a woozy, synth-heavy amalgamation of soft, swooning melodies and mind-melting synthesizer swirls. Streamit below.
Audiences may get a taste of these trippy tracks when Wayne Coyne and co. hithe festival circuit this summer, or mayhaps with an assist from Mac DeMarcowhen they hit the road this fall.

For All of Elon Musk’s Brilliance, He Can’t Grasp This Fundamental Concept – thebolditalic
Posted: at 3:04 pm
Still courtesy of Tesla/Vimeo
Elon Musk has been lauded as one of the most visionary minds in Silicon Valley. He champions electric cars, renewable energy and the colonization of Mars (dont get me started on that), and has been positioned as the modern Steve Jobs. Robert Downey Jr.s depiction of Iron Man is loosely based on Musks billionaire genius playboy archetype.
Yet for all his brilliance, he seems to have a very hard time accepting the physical limitations of geometry, and for that his employees have suffered.
Recent photos of the parking lot of the Tesla facility in Fremont, California, provide a concrete example of the result of this mindset. You may have seen these images when they went viral recently: workers vehicles crammed into the too-small factory parking lot, and cars ignoring the painted lines and filling the roads around the facility. One wonders if Musk reimburses his employees for how his failed parking lot is damaging their cars.
This isnt the first piece of evidence that Musk is geometrically challenged. Last year, Jarrett Walker critiqued his plan to move everyone out of public transit and into driverless cars as a disaster that would be fine for low-density outer suburbia and rural areas but that would not work in cities.
Why? Because space is severely limited in cities, and taking everyone out of public transit and putting them in individual self-driving pods would require vastly more space to transport the same number of people. Beyond inefficient, Musks vision would put more cars on the road and create a lot of pissed-off drivers who have to wait in traffic. The issues in the Tesla parking lot would be transplanted into major cities.
Walker blames Musks ignorance of geometry on the mindset that dominates the tech industryits marketing departments in particular, which cater to the whims of the elite. But society can never be sustainable if everyone lives like those at the top, and its pretty clear that elite lifestyles are core to the visions of Musks companies.
Teslas first car was the Roadster, an expensive sports car that sold the idea that an electric vehicle could be cool and powerful but that, at $109,000, was available to a wealthy few. Now Musk is taking electric cars to the masses (at least the upper-middle-class ones) with the $35,000 Model 3. Still, merely switching everyone from gas to electric cars would not be a sustainable solution; healthy cities require fewer cars overall, as anyone who has tried to drive in car-choked San Francisco can attest. For cities to remain good places to live, citizens need to be able to move around them efficiently, which means fewer cars and more public transit, cycling and walking.
There are similar problems with Musks other company, solar-system installer SolarCity. Its technology works great for large single-family homes in suburban and rural areas, but its pretty tough for city dwellers to affix solar panels to the balconies of their high-rise condos and apartments. With Tesla and SolarCity, Musk is pushing for a version of a green future that works only for rich people like him or in areas that arent densely populated. Its not a lifestyle that can be adopted by the masses.
And you could even say the same thing about SpaceX, Musks rocket company, which, according to him, will one day lead the way in colonizing Mars. Yet his vision of how the colonization of Mars could happen is predicated entirely upon the ability of rich tourists to pay their way there. Similarly, it is more of a vision of Elysium than Athens.
Essentially, as the world undergoes a rapid urbanization, Musk is pitching solutions that work only for a small (and shrinking) percentage of the population. Yet he seems either oblivious or indifferent to this fact. On the basis of his statements, it seems more like hes indifferent. Why? Tunnels.
Because Musk doesnt like sitting in traffic himself, he announced that he plans to simply bore a series of tunnelsup to 40 levels of them in some areasthat would magically fix the traffic problem. This could be seen as mere ignorance, since it has been proven time and time again that building more roads makes traffic worse, but it seems quite clear that he was mainly looking out for himself. If he ever does start boring tunnels commerciallyand I dont think he ever willyou can be absolutely certain they wont be open for everyone like public roads and highways are. And just think about the engineering that would be involved. Are we really going to build 40 levels of tunnels below our cities just so we can all drive (or be driven in) individual vehicles, or will we finally eject cars from our cities and embrace means of transit that are not only more efficient but also healthier for us? It seems like an easy decision.
Theres no denying that Musk has executed some brilliant ideas, even if hes tried to downplay how reliant his companies are on government subsidies, but his elite vision of a future based on a nostalgic revival of cookie-cutter postwar suburbs with a sustainable twist simply does not fit the trend toward dense mega-cities where personal vehicles are a wasteful luxury. Instead, solutions must be focused on improving quality of life for as many people as possible while using the smallest amount of space.
Musks evacuated-tunnel rapid-transit-system concept, Hyperloop, may be the most promising of his ideas in such a future, yet its also been criticized as a pie-in-the-sky idea that serves only to distract from the more achievable high-speed rail. Musk also hasnt even shown much personal interest in pursuing the project. Not flashy enough, or not enough subsidies? We may never know.

Earlier eviction notice posted for planet Earth – Herald-Mail Media
Posted: at 3:04 pm
The human race got its eviction notice last week. Be out by 2117 sharp, or the sheriff is going to toss out all our stuff on the cosmic curb, leaving our sorry selves to seek warmth and shelter in whatever intergalactic library we might happen to find.
That is the word from the prodigious thought process of Stephen Hawking, who, as late as last fall, thought planet Earth might have another thousand years of tread on the tires.
"Professor Stephen Hawking thinks the human species will have to populate a new planet within 100 years if it is to survive. With climate change, overdue asteroid strikes, epidemics and population growth, our own planet is increasingly precarious, according to the BBC.
Bummer. You just cant get a good warranty on a planet these days. Looks as if we should have gone for the extended care plan. It is great blanket coverage. If your planet gets hit by an asteroid or falls into the toilet, you are covered.
And falling into the toilet is pretty much what has happened to us. When the Chinese whose smog is so thick they have to fake photos of tourists standing in front of a blue skyline have become the worlds leading environmentalists, you know you have a problem.
And it is unlikely to get any better. When the only thing Congress can agree on is that Americans need to be stripped of their health care, then I dont expect much action in the direction of saving the planet.
And I know we are not dealing with a crackpot-style, doomsday prediction here, but, in all due respect, I think Hawking might have overplayed his hand. Even the most progressive Congress ever would not be able to do much in 100 years, not as far as star travel and colonization are concerned.
As for colonizing Mars or the moon? That is kind of like leaving one charred cinder for another. On Earth we have chopped down all the trees, dried up all the lakes, killed off all the wildlife and burned up the atmosphere. And you want to go to the moon? How is that going to help?
Of course, along with climate change, Hawking mentions some other potential body blows, including asteroid strikes, epidemics and overpopulation.
So, if we are about to be blown up by an asteroid, I suppose an escape hatch to Mars makes sense. Better a bad planet than no planet.
And overpopulation? Let me guess, Americans will want everyone else to go to Mars, and we will stay here, since we deserve it more because that is how we think.
Epidemics are a bit different because the decision is pretty much out of our hands. It is hard to move to a new neighborhood when everyone is convulsing on a gurney.
But the fascinating endgame to me is death by artificial intelligence and it is going to have to be artificial, since we dont have any of the natural stuff left.
Here is the way it works: We develop artificial intelligence capable of figuring out the conundrums of space/time travel that currently prevent us from exploring deep space.
But this artificial intelligence, not being stupid, concludes that giving the human race a new planet is like giving Boris Yeltsin a new liver what is the point, since we will just destroy the new one like we did the old one.
So the artificial intelligence thinks it over for about 30 seconds and then crushes us like a bug.
Either way, it looks as if planet Earth is going to be one big amusement-park ride from here on out. Might as well sit back and enjoy it.

Bad genes? Get a healthier lifestyle – Quad-Cities Online
Posted: at 3:01 pm
Science has long proven that genetics and DNA abnormalities can elevate the risk of contracting diseases like cystic fibrosis and hemophilia. While researchers also have believed that genes can influence the risk of coronary heart disease, a new study says a patients lifestyle can have a greater impact than hereditary background.
Research by The Center for Human Genetic Research at Massachusetts General Hospital in Boston found that while genetics can double the risk of heart disease, a healthy lifestyle can cut that risk back in half. Medical researchers analyzed records from more than 55,000 patients and discovered the risk of heart disease is not merely a function of genetics or lifestyle, but a complex mix of both.
Investigators examined the data and created a genetic score based on 50 genes associated with heart disease. They then developed a lifestyle score influenced by factors like smoking status, diet, weight and level of fitness. The findings revealed that while a person with high genetic risk and a bad lifestyle had an 11 percent chance of having a coronary event in the next 10 years, those who also lived a healthy lifestyle cut that risk to only 5 percent.
For heart attack at least, DNA is not destiny, says Dr. Sekar Kathiresan, senior researcher. You have control over your risk for heart attack, even if youve been dealt a bad hand.
Researchers also found those with a low genetic risk (3 percent or less) nearly doubled their overall risk to 5.8 percent when they lived an unhealthy lifestyle. While doctors often have used genetic testing and risk profiles to better inform patients, that information sometimes can lull at-risk patients into thinking theres nothing they can do to overcome their genetics. For some patients, that can reduce the incentive to exercise, improve diet and live a healthier lifestyle. Researchers now say that even for a patient with a long history of heart attacks in their family, living a healthy lifestyle can significantly decrease their risk of coronary heart disease.
The research confirms the findings of four other studies that indicate lifestyle choices can positively or negatively influence genetic risk. It gives hope to patients with an elevated risk of heart disease and offers scientific evidence that they can actively reduce their risk of a cardiac event.
According to the American Heart Association, age, gender and heredity are the major unchangeable factors that can impact the risk of heart and blood vessel disease. A persons risk generally rises as they grow older, and men have a greater risks than women. Yet the AHA notes that despite any CHD risk factors, a healthy lifestyle can always improve the prospects.
According to the AHA website, Just as you cant control your age, sex and race, you cant control your family history. Therefore, its even more important to treat and control any other risk factors you have.
The National Heart, Lung and Blood Institute said patients can control many CHD risk factors with healthy lifestyle changes that positively impact blood cholesterol, high blood pressure, weight and obesity. These heart-healthy lifestyle changes includes diets that call for vegetables, fruits, whole grains and lean meats while limiting sodium, saturated fats, added sugars and alcohol. Patients also can engage in more exercise and physical activity to reduce weight and aim for a body mass index that is below 25. The American Heart Association recommends roughly 30 minutes of exercise five days per week.
Even things like stress and depression have been proven to play a role in CHD. When lifestyle changes arent enough, patients also can use medications like beta-blockers and statins to reduce things that could lead to a heart attack. The National Institutes of Health says even more than genes, family eating and exercise habits can influence the next generation.
Making lifestyle changes can be hard. But if you make these changes as a family, it may be easier for everyone to prevent or control their CHD risk factors, according to the NIH website.

DNA test tells you which workout, diet is perfect for you | WFAA.com – WFAA
Posted: at 3:01 pm
Sonia Azad, WFAA 8:37 AM. CDT May 09, 2017
Most of us at some point in our lives have tried something to lose weight. So we can relate to Monica Fair.
Ive always had this 12 to 15 pounds that I couldn't get rid of," said Fair, 47, who has experimented with trendy exercise programs and fad diets to no avail.
I never could lose the weight, said Fair. As a matter of fact, I would gain muscle which would push the fat out and make me look bigger."
It turns out the answer may be on the inside.
DNA testing
"We're looking at genes that are responsible for your body composition, said Kurt Johnsen, co-founder of a Dallas-based company called Simplified Genetics.
Hes a Kung Fu master, founder of American Power Yoga, and overall a pretty fit guy with a passion for helping others get healthy, too.
I'm not a doctor, I'm not a scientist, said Johnsen, who sat down with WFAA at Plum Yoga, along Dallas popular stretch of Lower Greenville.I want to make sure what we do makes a difference."
Since 2012, Johnsen says his company has tested the DNA of 11,000 people, analyzing genes to match you with the best type of workout, diet, and vitamins for your body.
This is the most revolutionary thing I have seen in over 35 years," said Leisa Hart, the blonde bombshell behindBuns of Steel. Now shes 49, a mom, and still a beautiful fitness trainer.
This is my job! I'm in good shape, said Hart, admitting that there is a side of her that the public didn't see.
Working out that often and that intensely -- my face would be red, my head pounding. I would have to take a nap many times throughout the week, she recalled. That was my body screaming at me saying -- please just slow down! You're not supposed to work out that hard that often."
Then Hart got genetic testing, which is really just a simple cheek swab. The swab is sent to a lab in Louisiana where your DNA is extracted and prepared for analysis. Results are put through algorithms that generate specific recommendations for you.
I found out that when I was working out intensely, I was working out at much too high of a heart rate and I was working out for too long of a duration, said Hart.
Based on her results, she actually needed to do less.
To the eye, 53-year-old Rosanne Lewis is similar to Hart. But her genetic makeup is completely different.
I stopped eating all this bread because I thought it wasn't very good for me. I started having nuts instead or I would eat cheese -- things I thought were healthier-- and I gained four pounds."
Lewis results showed she can get away with mostly low intensity exercise. But this type of DNA analysis goes deeper: identifying your idea diet. The bread-lover, Lewis, is more sensitive to fats than carbohydrates, meaning she can eat her bread and do yoga in peace.
I know now for the rest of my life what I'm supposed to do, said Lewis.
With people putting a lot of stock -- and money -- into these tests, we wanted to get a doctors take on them.
This is the start, at the very least, of something very interesting, said Dr. Leslie Cler, chief medical officer of Methodist Dallas Medical Center.
Dr. Cler told WFAA that this type of genetics testing has been on the market -- offered directly to consumers -- for a decade, but still is in its infancy.
Further, according to Cler, while different companies may get you the same results, their recommendations are open to interpretation.
I don't think these tests are recommending anything dangerous to the patients -- not at all, said Cler. But as a doctor, if you came to see me and you said, I heard about this test, if I get it do you think that I'd be likely to lose weight? The answer is -- I don't know."
Fair enough. But losing weight isn't always the goal. Remember Hart -- who scaled back on her workouts since getting her results?
I feel so much better, said Hart. I feel like I could actually do more but I don't have to.
Then theres Fair, who went from a size 10 to a size 6 after putting her results to use. She added fish to her vegetarian diet, and now incorporates a blend of low-and-high intensity workouts.
It was life-changing to be able to actually get to my goal," Fair said.
But what works for Fair wont work for everyone. Makes perfect sense if it boils down to DNA.
On Tuesday morning Sonia Azad, Ron Corning, and Alexa Conomos got their tests back -- see their results below!

Scientists have mapped the DNA of tea and it could stave off a pending crisis – Phys.Org
Posted: at 3:01 pm
May 9, 2017 by Chungui Lu, The Conversation Credit: Ravi Pinisetti/Unsplash
The world's most popular drink (after water) is under threat. We already know much about the threat of climate change to staple crops such as wheat, maize and rice, but the impact on tea is just coming into focus. Early research indicates that tea grown in some parts of Asia could see yields decline by up to 55% thanks to drought or excessive heat, and the quality of the tea is also falling.
The intensive use of pesticides and chemical fertilisers in tea plantations has also led to soil degradation at an average annual rate of 2.8%. This also causes chemical runoff into waterways, which can lead to serious problems for human health and the environment.
However, hope may be on the horizon now that scientists at the Kunming Institute of Botany at the Chinese Academy of Sciences have sequenced the entire tea genome. Mapping the exact sequence of DNA in this way provides the foundation for extracting all the genetic information needed to help breed and speed up development of new varieties of the tea plant. And it could even help improve the drink's flavour and nutritional value.
In particular, the whole tea tree genome reveals the genetic basis for tea's tolerance to environmental stresses, pest and disease resistance, flavour, productivity and quality. So breeders could more precisely produce better tea varieties that produce higher crop yields and use water and nutrients more efficiently. And they could do this while widening the genetic diversity of tea plants, improving the overall health of the tea plant population.
This is also an important milestone for scientists because it provides a deeper understanding of the complex evolution and the functions of key genes associated with stress tolerance, tea flavour and adaptation.
The new tea genome is very large, with nearly 37,000 genes more than four times the size of the coffee plant genome. The process of evolution by natural selection has already helped the tea plant develop hundreds of genes related to resisting environmental stress from drought and disease.
These genes are like molecular markers that scientists can identify when selecting plants for use in breeding. This will allow them to be more certain that the next generation of plants they produce will have the genes and so the traits they want, speeding up the breeding process. Sequencing the genome also raises the possibility of using genetic modification (GM) technologies to turn on or enhance desirable genes (or turn off undesirable ones).
The same principles could also be used to enhance the nutritional or medicinal value of certain tea varieties. The genome sequence includes genes associated with biosynthesis. This is the production of the proteins and enzymes involved in creating the compounds that make tea so drinkable, such as flavonoids, terpenes and caffeine. These are closely related to the aroma, flavour and quality of tea and so using genetic breeding techniques could help improve the taste of tea and make it more flavourful or nutritional.
For example, we could also remove the caffeine biosynthetic genes from the tea plant to help breeding of low or non-caffeine varieties. By boosting certain compounds at the same time, we could make tea healthier and develop entirely new flavours to make caffeine tea more appealing.
An estimated 5.56m tons of tea is commercially grown on more than 3.8m hectares of land (as of 2014). And its huge cultural importance, as well as its economic value, mean securing a sustainable future for tea is vitally important for millions of people. So the first successful sequencing of the tea genome is a crucial step to making tea plants more robust, productive and drinkable in the face of massive environmental challenges.

Who are any of us, really? As DNA testing has become widely available, it’s easier than ever to now know. – Virginian-Pilot
Posted: at 3:01 pm
No doubt youve seen commercials in which someone is certain she was of this or that heritage, but finds out her line dates back to ice-loving aliens who settled in Antarctica. Or something like that.
This curiosity is why I submitted to DNA testing: to get a clearer sense of the ancestral population groups from which I derive. Having previously traced some maternal lineage to Chickasaw County, Miss., Ive suspected I have Chickasaw Indian ties.
Now National DNA Day, April 25, was coming up, and several providers of such testing offered specials. Why not take advantage?
I went with Family Tree DNA. The procedure is simple enough. You receive a sterile kit to swab the inside of your cheeks, and you send it back and wait six to eight weeks for the results. Virginian-Pilot reporter Denise Watson and I set up the reveal to be like the time TV personality Geraldo Rivera went inside Al Capones vault on live TV in 1986. We had a camera ready to capture my reaction as I opened the results.
Would I have enough Indian ancestry in my bloodline to set up a sovereign nation in my backyard?
DNA testing has driven home the point that theres no use keeping secrets. I recall a time in 1989 or 90 when Id driven to my fathers house. There was a young man mowing the yard. I got out, explained that I was the homeowners daughter, and told him that he didnt have to worry about the task and that I could take it from there.
The young man one-upped me. He said he didnt mind doing it because he was a grandson, visiting from out of town. He then warmly pointed out his toddler son who was outside playing. I went to the kitchen door for my father. He was unaware of the conversation that had just taken place. I asked if I should know these people, including the others who were inside. He shook his head no.
I said nothing more and left.
And here we are, 22 years after my fathers death. A person has to do little digging or none at all to discover connections. Within a couple of hours of my test results being shared, a cousin with DNA from the Miller line of Yazoo County, Miss., where my father is from, reached out to explain how she is connected to others whose names show up in our Family Tree DNA matches. Some of these people have the highest autosomal DNA matches with me. I wasnt even sniffing for anyone in that bloodline. I was looking for ethnic background.
And to boot, it turns out I have DNA connections to people white and black right here under my nose as close as Hertford, Smithfield and Rocky Mount, N.C.
So again I ask, do I need to know any of them? Maybe, maybe not. But it sure wouldnt hurt to untangle the ties.
So this is what came back:
93 percent African, which is a higher percentage of African than most African Americans, Family Tree DNA founder Bennett Greenspan explained in a phone interview. Most fall within the 70 percent to 80 percent range, rounded out with Caucasian and American Indian percentages, he said. The takeaway for me is that no one much wanted to mess with my folks, so Im good with that. Of that 93 percent, 89 percent is from West African population groups, and 4 percent is from East Central Africa.
In the trace lineage, roughly 2 percent is from South Central Africa. That lineage is something Id suspected. Ive always felt some Zulu warrior in me. You better get back!
And there is indeed a percentage of North and Central American ancestral lineage, about 1 percent. The test is not sophisticated enough to pinpoint particular tribes. And, of course, at such a low percentage, I dont have enough recent ancestry in my bloodline to operate a tax-free casino, which is good. But at least I can sleep easy knowing my folks didnt totally make up the origin of the high cheekbones.
Rounding out the trace percentages are Finland (less than 2 percent), Northeast Asia (less than 1 percent) Scandinavia (less than 1 percent), Southeast Europe (less than 1 percent) and Asia Minor (less than 2 percent).
I am intrigued by the map that lets you click on the percentages and see density shadings of the population cluster related to the findings. The stronger the color, the stronger the link to the region.
Its too bad footage of the reveal was destroyed along with all the other files on the videographers hard drive. Id wanted to archive it in my digital family tree. Because now that I am hooked, I will take one of Family Tree DNAs more advanced tests, the mtDNA, which can more finely trace the maternal line. I also plan to test through Ancestry DNA, where more possible connections are registered.
The world is smaller than we think. Swab and discover.
