NASA Delays First Flight of New SLS Rocket Until 2019 (arstechnica.com) 47

schwit1 writes: Despite spending almost $19 billion and more than thirteen years of development, NASA today admitted that it will have to delay the first test flight of the SLS rocket from late 2018 to sometime in 2019. "We agree with the GAO that maintaining a November 2018 launch readiness date is not in the best interest of the program, and we are in the process of establishing a new target in 2019," wrote William Gerstenmaier, chief of NASA's human spaceflight program. "Caution should be used in referencing the report on the specific technical issues, but the overall conclusions are valid." The competition between the big government SLS/Orion program and private commercial space is downright embarrassing to the government. While SLS continues to be delayed, even after more than a decade of work and billions of wasted dollars, SpaceX is gearing up for the first flight of Falcon Heavy this year. And they will be doing it despite the fact that Congress took money from the commercial private space effort, delaying its progress, in order to throw more money at SLS/Orion.

DNA-Based Test Can Spot Cancer Recurrence a Year Before Conventional Scans (theguardian.com) 21

An anonymous reader quotes a report from The Guardian: A revolutionary blood test has been shown to diagnose the recurrence of cancer up to a year in advance of conventional scans in a major lung cancer trial. The test, known as a liquid biopsy, could buy crucial time for doctors by indicating that cancer is growing in the body when tumors are not yet detectable on CT scans and long before the patient becomes aware of physical symptoms. It works by detecting free-floating mutated DNA, released into the bloodstream by dying cancer cells. In the trial of 100 lung cancer patients, scientists saw precipitous rises in tumor DNA in the blood of patients who would go on to relapse months, or even a year, later. In the latest trial, reported in the journal Nature, 100 patients with non-small cell lung cancer were followed from diagnosis through surgery and chemotherapy, having blood tests every six to eight weeks. By analyzing the patchwork of genetic faults in cells across each tumor, scientists created personalized genomic templates for each patient. This was then compared to the DNA floating in their blood, to assess whether a fraction of it matched that seen in their tumor.

US Space Firms Tell Washington: China Will Take Over the Moon if You're Not Careful (yahoo.com) 144

The US space industry is prodding the US government into refreshing its outdated laws on commercial activity beyond earth: scare it with talk of Chinese galactic domination. A report adds: At a Senate hearing on the space industry this week, companies that build rockets and space habitats and manufacture electronic goods in space spoke about a standard laundry list of complaints, from regulatory burdens to fears of subsidized competitors. But their message was wrapped in patriotic concerns about China's growing capacity for space action. These companies are eager for the US government to allow and invest in commercial activities in orbit and around the moon. Many think the laws governing action in space, and particularly the UN Space Treaty, need refreshing for an age when private companies are close to matching the space capacity of sovereign nations. The last major change was a law on asteroid mining passed in 2015.

LinkedIn Testing 1970's-Style No-CS-Degree-Required Software Apprenticeships (mercurynews.com) 185

theodp writes: The Mercury News reports on REACH, a new software apprenticeship program that LinkedIn's engineering team started piloting this month, which offers people without Computer Science degrees an opportunity to get a foot in the door, as Microsoft-owned LinkedIn searches for ways to help diversify its workforce. For now, the 29 REACH participants are paid, but are only short-term LinkedIn employees (for the duration of the 6-month program). LinkedIn indicated it hopes to learn if tech internships could eventually be made part of the regular hiring process, perhaps unaware that no-CS-degree-required hiring for entry-level permanent positions in software development was standard practice in the 70's and 80's, back when women made up almost 40% of those working as programmers and in software-related fields, nearly double the percentage of women in LinkedIn's global 2016 tech workforce. Hey, even in tech hiring, everything old is new again!

NASA Inspector Says Agency Wasted $80 Million On An Inferior Spacesuit (arstechnica.com) 75

An anonymous reader quotes a report from Ars Technica: When NASA began developing a rocket and spacecraft to return humans to the Moon a decade ago as part of the Constellation Program, the space agency started to think about the kinds of spacesuits astronauts would need in deep space and on the lunar surface. After this consideration, NASA awarded a $148 million contract to Oceaneering International, Inc. in 2009 to develop and produce such a spacesuit. However, President Obama canceled the Constellation program just a year later, in early 2010. Later that year, senior officials at the Johnson Space Center recommended canceling the Constellation spacesuit contract because the agency had its own engineers working on a new spacesuit and, well, NASA no longer had a clear need for deep-space spacesuits. However, the Houston officials were overruled by agency leaders at NASA's headquarters in Washington, DC. A new report released Wednesday by NASA Inspector General Paul Martin sharply criticizes this decision. "The continuation of this contract did not serve the best interests of the agency's spacesuit technology development efforts," the report states. In fact, the report found that NASA essentially squandered $80.6 million on the Oceaneering contract before it was finally ended last year.

Chinese, European Space Agencies In Talks To Build a Moon Base (techcrunch.com) 87

ESA's Pal Hvistendahl has confirmed via Bloomberg that Chinese and European space agencies are talking with one another about plans to build a base on the moon. The discussions "involve working together to build a human-occupied 'moon village' from which both agencies can potentially launch Mars missions, conduct research, and possibly explore commercial mining and tourism projects," reports TechCrunch. From the report: China's upcoming projects in space include a mission to collect samples from the moon via an uncrewed craft by the end of this year, and to also launch an exploratory mission to the far side of the moon next year, with the similar aim of returning samples for study. The ESA's collaboration with China thus far include participating in the study of those returned samples, and potentially sending a European astronaut to the Chinese space station (which is currently unoccupied) at some future date.

Popular Belief That Saturated Fat Clogs Up Arteries Is a Myth, Experts Say (independent.ie) 254

schwit1 quotes a report from Irish Independent: The authors, led by Dr Aseem Malhotra, from Lister Hospital, Stevenage, wrote: "Despite popular belief among doctors and the public, the conceptual model of dietary saturated fat clogging a pipe is just plain wrong." Dr Malhotra and colleagues Professor Rita Redberg, from the University of California at San Francisco, and Pascal Meier from University Hospital Geneva in Switzerland and University College London, cited a "landmark" review of evidence that appeared to exonerate saturated fat. They said relative levels of "good" cholesterol, or high density lipoprotein (HDL), were a better predictor of heart disease risk than levels of low density lipoprotein (LDL), also known as "bad" cholesterol. High consumption of foods rich in saturated fat such as butter, cakes and fatty meat has been shown to increase blood levels of LDL. The experts wrote: "It is time to shift the public health message in the prevention and treatment of coronary artery disease away from measuring serum lipids (blood fats) and reducing dietary saturated fat. "Coronary artery disease is a chronic inflammatory disease and it can be reduced effectively by walking 22 minutes a day and eating real food." They pointed out that in clinical trials widening narrow arteries with stents -- stainless steel mesh devices -- failed to reduce the risk of heart attacks.

New Study Suggests Humans Lived In North America 130,000 Years Ago (npr.org) 224

An anonymous reader writes: In 1992, archaeologists working a highway construction site in San Diego County found the partial skeleton of a mastodon, an elephant-like animal now extinct. Mastodon skeletons aren't so unusual, but there was other strange stuff with it. "The remains were in association with a number of sharply broken rocks and broken bones," says Tom Demere, a paleontologist at the San Diego Natural History Museum. He says the rocks showed clear marks of having been used as hammers and an anvil. And some of the mastodon bones as well as a tooth showed fractures characteristic of being whacked, apparently with those stones. It looked like the work of humans. Yet there were no cut marks on the bones showing that the animal was butchered for meat. Demere thinks these people were after something else. "The suggestion is that this site is strictly for breaking bone," Demere says, "to produce blank material, raw material to make bone tools or to extract marrow." Marrow is a rich source of fatty calories. The scientists knew they'd uncovered something rare. But they didn't realize just how rare for years, until they got a reliable date on how old the bones were by using a uranium-thorium dating technology that didn't exist in the 1990s. The bones were 130,000 years old. That's a jaw-dropping date, as other evidence shows that the earliest humans got to the Americas about 15,000 to 20,000 years ago. The study has been published in the journal Nature.

Will the High-Tech Cities of the Future Be Utterly Lonely? (theweek.com) 106

adeelarshad82 writes from a report via The Week: The prospect of cities becoming sentient is "fast becoming the new reality," according to one paper. Take Tel Aviv for example, where everyone over the age of 13 can receive personalized data, such as traffic information, and can access free municipal Wi-Fi in 80 public zones. But in a future where robots sound and objects look increasingly sentient, we might be less inclined to seek out behaviors to abate our loneliness. Indeed, one recent study titled "Products as pals" finds that exposure to or interaction with anthropomorphic products -- which have characteristics of being alive -- partially satisfy our social needs, which means the human-like robots of tomorrow could kill our dwindling urge to be around other humans.

Mylan's Epic EpiPen Price Hike Wasn't About Greed -- It's Worse, Lawsuit Claims (arstechnica.com) 155

Mylan engaged in a campaign to squash a rival to its EpiPen allergy treatment and artificially inflate the price of the drug to maintain a market monopoly, French drugmaker Sanofi said in a lawsuit. From a report: With the lofty prices and near-monopoly over the market, Mylan could dangle deep discounts to drug suppliers -- with the condition that they turn their backs on Sanofi's Auvi-Q -- the lawsuit alleges. Suppliers wouldn't dare ditch EpiPens, the most popular auto-injector. And with the high prices, the rebates wouldn't put a dent in Mylan's hefty profits, Sanofi speculates. Coupled with a smear campaign and other underhanded practices, Mylan effectively pushed Sanofi out of the US epinephrine auto-injector market, Sanofi alleges. The lawsuit, filed Monday in a federal court in New Jersey, seeks damages under US Antitrust laws.

Sergey Brin Is Reportedly Building 'Massive Airship' In NASA Research Center (bloomberg.com) 119

Google co-founder Sergey Brin is secretly building a "massive airship" inside of Hangar 2 at the NASA Ames Research Center, according to a report from Bloomberg. "It's unclear whether the craft, which looks like a zeppelin, is a hobby or something Brin hopes to turn into a business," reports Bloomberg. When asked about further details, Brin wrote in an email: "Sorry, I don't have anything to say about this topic right now." From the report: The people familiar with the project said Brin has long been fascinated by airships. His interest in the crafts started when Brin would visit Ames, which is located next to Google parent Alphabet Inc.'s headquarters in Mountain View, California. In the 1930s, Ames was home to the USS Macon, a huge airship built by the U.S. Navy. About three years ago, Brin decided to build one of his own after ogling old photos of the Macon. In 2015, Google unit Planetary Ventures took over the large hangars at Ames from NASA and turned them into laboratories for the company. Brin's airship, which isn't an Alphabet project, is already taking shape inside one. Engineers have constructed a metal skeleton of the craft, and it fills up much of the enormous hangar. Alan Weston, the former director of programs at NASA Ames, is leading Brin's airship project, according to the people, who asked not to be named discussing the secretive plans. Weston didn't respond to requests for comment.

An Artificial Womb Successfully Grew Baby Sheep -- and Humans Could Be Next (theverge.com) 185

An anonymous reader quotes a report from The Verge: Inside what look like oversized ziplock bags strewn with tubes of blood and fluid, eight fetal lambs continued to develop -- much like they would have inside their mothers. Over four weeks, their lungs and brains grew, they sprouted wool, opened their eyes, wriggled around, and learned to swallow, according to a new study that takes the first step toward an artificial womb. One day, this device could help to bring premature human babies to term outside the uterus -- but right now, it has only been tested on sheep. The Biobag may not look much like a womb, but it contains the same key parts: a clear plastic bag that encloses the fetal lamb and protects it from the outside world, like the uterus would; an electrolyte solution that bathes the lamb similarly to the amniotic fluid in the uterus; and a way for the fetus to circulate its blood and exchange carbon dioxide for oxygen. Flake and his colleagues published their results today in the journal Nature Communications.

Oregon Fines Man For Writing a Complaint Email Stating 'I Am An Engineer' (vice.com) 715

pogopop77 quotes a report from Motherboard: In September 2014, Mats Jarlstrom, an electronics engineer living in Beaverton, Oregon, sent an email to the state's engineering board. The email claimed that yellow traffic lights don't last long enough, which "puts the public at risk." "I would like to present these facts for your review and comments," he wrote. This email resulted not with a meeting, but with a threat from The Oregon State Board of Examiners for Engineering and Land Surveying [stating]: "ORS 672.020(1) prohibits the practice of engineering in Oregon without registration -- at a minimum, your use of the title 'electronics engineer' and the statement 'I'm an engineer' create violations." In January of this year, Jarlstrom was officially fined $500 by the state for the crime of "practicing engineering without being registered." Since the engineering board in Oregon said Jarlstrom should not be free to publish or present his ideas about the fast-turning yellow traffic lights, due to his "practice of engineering in Oregon without registration," he and the Institute for Justice sued them in federal court for violating his First Amendment rights. "I'm not practicing engineering, I'm just using basic mathematics and physics, Newtonian laws of motion, to make calculations and talk about what I found," he said. Sam Gedge, an attorney for the Institute for Justice, told Motherboard: "Mats has a clear First Amendment right to talk about anything from taxes to traffic lights. It's an instance of a licensing board trying to suppress speech."

A Caterpillar May Lead To a 'Plastic Pollution' Solution (bbc.com) 70

New submitter FatdogHaiku quotes a report from BBC: Researchers at Cambridge University have discovered that the larvae of the moth, which eats wax in bee hives, can also degrade plastic. Experiments show the insect can break down the chemical bonds of plastic in a similar way to digesting beeswax. The plastic is used to make shopping bags and food packaging, among other things, but it can take hundreds of years to decompose completely. However, caterpillars of the moth (Galleria mellonella) can make holes in a plastic bag in under an hour. They think microbes in the caterpillar -- as well as the insect itself -- might play a role in breaking down plastic. If the chemical process can be identified, it could lead to a solution to managing plastic waste in the environment.

World's First Vaccine Against Malaria To Arrive Next Year, Says WHO (bbc.com) 84

An anonymous reader shares a report: The world's first vaccine against malaria will be introduced in three countries -- Ghana, Kenya and Malawi -- starting in 2018. The RTS,S vaccine trains the immune system to attack the malaria parasite, which is spread by mosquito bites. The World Health Organization (WHO) said the jab had the potential to save tens of thousands of lives. But it is not yet clear if it will be feasible to use in the poorest parts of the world. The vaccine needs to be given four times -- once a month for three months and then a fourth dose 18 months later.

Aurora Enthusiasts Discover A Strange New Light In The Sky And Named It Steve (bbc.com) 56

An anonymous reader quotes the BBC: A group of aurora enthusiasts have found a new type of light in the night sky and named it Steve. Eric Donovan from the University of Calgary in Canada spotted the feature in photos shared on a Facebook group. He did not recognise it as a catalogued phenomenon and although the group were calling it a proton arc, he knew proton auroras were not visible. Testing showed it appeared to be a hot stream of fast-flowing gas in the higher reaches of the atmosphere.

The European Space Agency sent electric field instruments to measure it 300km (190 miles) above the surface of the Earth and found the temperature of the air was 3,000C (5,400F) hotter inside the gas stream than outside it. Inside, the 25km-wide ribbon of gas was flowing at 6 km/s (13,000mph), 600 times faster than the air on either side.

One official at the European Space Agency made sure to thank the "army of citizen scientists" who helped with the discovery, saying "It turns out that Steve is actually remarkably common, but we hadn't noticed it before." The name apparently came from a scene in the movie "Over the Hedge."

Scientists Consider 'Cloud Brightening' To Preserve Australia's Great Barrier Reef (technologyreview.com) 108

An anonymous reader quotes MIT Technology Review: A group of Australian marine scientists believe that altering clouds might offer one of the best hopes for saving the Great Barrier Reef. For the last six months, researchers at the Sydney Institute of Marine Science and the University of Sydney School of Geosciences have been meeting regularly to explore the possibility of making low-lying clouds off the northeastern coast of Australia more reflective in order to cool the waters surrounding the world's biggest coral reef system...

Last year, as El Nino events cranked up ocean temperatures, at least 20% of the reef died and more than 90% of it was damaged. The Australian researchers took a hard look at a number of potential ways to preserve the reefs. But at this point, making clouds more reflective looks like the most feasible way to protect an ecosystem that stretches across more than 130,000 square miles, says Daniel Harrison, a postdoctoral research associate with the Ocean Technology Group at the University of Sydney. Cloud brightening is the only thing we've identified that's scalable, sensible, and relatively environmentally benign," he says... Next month, he plans to start computer climate modeling to explore whether cloud brightening could make a big enough temperature difference to help.

They're collaborating with Silicon Valley's Marine Cloud Brightening Project, which has spent the last seven years "developing a nozzle that they believe can spray salt particles of just the right size and quantity to alter the clouds. They're attempting to raise several million dollars to build full-scale sprayers." The article describes them as "one of several research groups that have started to explore whether cloud brightening, generally discussed as a potential tool to alter the climate as a whole, could be applied in more targeted ways."

'Detergent' Hydroxl Molecules May Affect Methane Levels In The Atmosphere (caltech.edu) 68

An anonymous reader quotes Caltech's announcement about the results of a study funded by NASA and the Department of Energy: During the early 2000s, environmental scientists studying methane emissions noticed something unexpected: the global concentrations of atmospheric methane -- which had increased for decades, driven by methane emissions from fossil fuels and agriculture -- inexplicably leveled off. The methane levels remained stable for a few years, then started rising again in 2007... New modeling by researchers at Caltech and Harvard University suggests that methane emissions might not have increased dramatically in 2007 after all. Instead, the most likely explanation has less to do with methane emissions and more to do with changes in the availability of the hydroxyl radical, which breaks down methane in the atmosphere... If global levels of hydroxyl decrease, global methane concentrations will increase -- even if methane emissions remain constant, the researchers say...

Tracking decadal trends in both methane and hydroxyl, Christian Frankenberg and his colleagues noted that fluctuations in hydroxyl concentrations correlated strongly with fluctuations in methane... "Think of the atmosphere like a kitchen sink with the faucet running," Frankenberg explains. "When the water level inside the sink rises, that can mean that you've opened up the faucet more. Or it can mean that the drain is blocking up. You have to look at both."

So what's changing the level of hydroxl in the atmosphere? The researchers say they have no idea.
