Medicine 50

As reported by Bloomberg News, The Washington Post, and other outlets, the Liberian patient whose diagnosis of Ebola infection marks him as the first such case to have been first diagnosed within the United States may have had contact with more people than previously estimated, and 80 people in the Dallas area are now believed to have come into contact with him. While Bloomberg reports that this larger group of potential contacts is "being monitored for symptoms," the Washington Post's slightly later story says that, in keeping with the best current knowledge about Ebola's spread, "Dallas County Health and Human Services Director Zachary Thompson said that these [newly identified contacts] are not being watched or monitored and are not showing any symptoms of the illness. Only the immediate family members of the victim are being regularly monitored for Ebola symptoms; they've been ordered to stay at home and avoid contact with others."

ISS 25

SternisheFan writes Canada's robotic Canadarm2 will install the next two Urthecast cameras on the International Space Station, removing the need for astronauts to go outside to do the work themselves. Urthecast plans to place two Earth-facing cameras on the United States side of the station (on Node 3) to add to the two they already have on the Russian Zvezda module. Technical problems with the cameras forced the Russians to do an extra spacewalk to complete the work earlier this year.

the eric conspiracy writes "Lack of sea ice in the Arctic has forced record numbers of walrus to come ashore in Alaska. The walrus, looking for a place to rest have come ashore in Point Lay Alaska. The walrus normally rest on floating ice. "We are witnessing a slow-motion catastrophe in the Arctic," Lou Leonard, vice president for climate change at the World Wildlife Fund, said in a statement that was reported by CNN. "As this ice dwindles, the Arctic will experience some of the most dramatic changes our generation has ever witnessed. This loss will impact the annual migration of wildlife through the region, threaten the long-term health of walrus and polar bear populations, and change the lives of those who rely on the Arctic ecosystem for their way of life."

aarondubrow writes The ability to collect and analyze massive amounts of data is transforming science, industry and everyday life. But what we've seen so far is likely just the tip of the iceberg. As part of an effort to improve the nation's capacity in data science, NSF today announced $31 million in new funding to support 17 innovative projects under the Data Infrastructure Building Blocks (DIBBs) program, including data infrastructure for education, ecology and geophysics. "Each project tests a critical component in a future data ecosystem in conjunction with a research community of users," said said Irene Qualters, division director for Advanced Cyberinfrastructure at NSF. "This assures that solutions will be applied and use-inspired."

Study: Compound Found In Beer Boosts Brain Function

Beer 95

An anonymous reader writes Researchers have found that a chemical found in hops may actually improve memory. Unfortunately, a person would need to drink 3,520 pints of beer a day to get a high enough dose of the chemical to boost their brain power. A daunting task for even the most enthusiastic Oktoberfest participant. From the article: "Researchers at Oregon State University discovered that doses of xanthohumol, a flavonoid found in hops, improved memory and thinking in a lucky group of mice. Flavonoids are a class of compounds present in plants, known to have numerous health benefits. Last year, researchers discovered that a flavonoid found in celery and artichokes could potentially fight pancreatic cancer. The researchers treated the mice with dietary supplements of xanthohumol over the course of eight weeks. Their goal was to determine if xanthohumol could affect palmitoylation, a naturally occurring process in animals (including humans) that's associated with memory degradation. The mice then went through a series of tests—including the popular Morris water maze—to gauge whether or not the treatments had improved their spatial memory and cognitive flexibility. For the younger mice in the group, it worked. But on the older mice, unfortunately, the xanthohumol didn't seem to have any effect."

The "Man In the Moon" Was Created By Mega Volcano

Moon 31

astroengine writes Whenever you look up at the near side of the moon, you see a face looking back at you. This is the "Man in the Moon" and it has inspired many questions about how it could have formed. There has been some debate as to how this vast feature — called Oceanus Procellarum, which measures around 1,800 miles wide — was created. But after using gravity data from NASA's twin GRAIL spacecraft, researchers have found compelling evidence that it was formed in the wake of a mega volcanic eruption and not the location of a massive asteroid strike.

Earth Gets Another Quasi-Moon

The Bad Astronomer writes Astronomers have found a new asteroid, 2014 OL339, that is a quasi-moon of the Earth. Discovered accidentally earlier this year, the 150-meter asteroid has an orbit that is more elliptical than Earth's, but has a period of almost exactly one year. It isn't bound to Earth like a real moon, but displays apparent motion as if it did, making it one of several known quasi-moons.

Back To Faxes: Doctors Can't Exchange Digital Medical Records

Soulskill posted yesterday | from the have-you-tried-paper-airplanes dept.

Communications 228

nbauman writes: Doctors with one medical records system can't exchange information with systems made by other vendors, including those at their own hospitals, according to the New York Times. One ophthalmologist spent half a million dollars on a system, but still needs to send faxes to get the information where it needs to go. The largest vendor is Epic Systems, Madison, WI, which holds almost half the medical records in the U.S. A report from RAND described Epic as a "closed" platform that made it "challenging and costly" for hospitals to interconnect.

The situation is bad for patients and costly for medical works: if doctors can't exchange records, they'll face a 1% Medicare penalty, and UC Davis alone has a staff of 22 dedicated to communication. On top of that, Epic charges a fee to send data to some non-Epic systems. Congress has held hearings on the matter, and Epic has hired a lobbyist. Epic's founder, billionaire computer science major Judith Faulkner, said that Epic was one of the first to establish code and standards for secure interchange, which included user authentication provisions and a legally binding contract. She said the federal government, which gave $24 billion in incentive payments to doctors for computerization, should have done that. The Office of the National Coordinator for Health Information Technology said that it was a "top priority" and just recently wrote a 10-year vision statement and agenda for it.

Aral Sea Basin Almost Completely Dry

Earth 144

An anonymous reader writes: In 2000, NASA began taking satellite images of the Aral Sea in central Asia, which was once the fourth-largest inland lake in the world. At that time, there was an expansive eastern basin, and smaller basins to the north and west. In images recorded just last week, we see that the eastern basin is completely gone, and the western basin just a thin strip of water. The local fishing industry has been devastated, old ship graveyards now rest on dry ground, and salt-heavy sand is being blown around the region, causing health issues.

Most of the lake's decline is attributable to human intervention: "In the 1950s, two of the region's major rivers – the Amu Darya and and the Syr Darya – were diverted by the Soviet government to provide irrigation for cotton production in Uzbekistan and Turkmenistan, starving the Aral. It has been diminishing ever since, with the sea level dropping 16 meters between 1960 and 1996, according to the World Bank. Water levels are believed to be down to less than 10 per cent of what they were five decades ago." Low levels of rain and snow didn't help.

Elon Musk: We Must Put a Million People On Mars To Safeguard Humanity

Mars 505

An anonymous reader writes: Elon Musk's ambitions for SpaceX keep getting bigger. First he wanted to make the trip to Mars affordable, then he wanted to establish a city-sized colony, and now he's got his eye on the future of humanity. Musk says we need a million people on Mars to form a "sustainable, genetically diverse civilization" that can survive as humanity's insurance policy. He continued, "Even at a million, you're really assuming an incredible amount of productivity per person, because you would need to recreate the entire industrial base on Mars. You would need to mine and refine all of these different materials, in a much more difficult environment than Earth. There would be no trees growing. There would be no oxygen or nitrogen that are just there. No oil." How fast could we do it? Within a century, once the spacecraft reusability problem is solved. "Excluding organic growth, if you could take 100 people at a time, you would need 10,000 trips to get to a million people. But you would also need a lot of cargo to support those people. In fact, your cargo to person ratio is going to be quite high. It would probably be 10 cargo trips for every human trip, so more like 100,000 trips. And we're talking 100,000 trips of a giant spaceship."

David Cameron Says Brits Should Be Taught Imperial Measures

00_NOP writes: Children in the U.K. have been taught in metric measures in school since (at least) 1972, but yesterday British Prime Minister David Cameron suggested that they should actually be taught in Imperial measures (which are still in use officially to measure road distances and speeds, but not really anywhere else). Is this because he hasn't a clue about science or because he is catering to a particular political base?

Mysterious Feature Appears and Disappears In a Sea On Titan

Soulskill posted yesterday | from the interplanetary-game-of-battleship dept.

Space 65

schwit1 writes: Cassini images taken in 2007, 2013, and 2014 of one of Titan's largest hydrocarbon seas find that a mysterious feature there keeps appearing and disappearing. Quoting: "The mysterious feature, which appears bright in radar images against the dark background of the liquid sea, was first spotted during Cassini's July 2013 Titan flyby. Previous observations showed no sign of bright features in that part of Ligeia Mare. Scientists were perplexed to find the feature had vanished when they looked again, over several months, with low-resolution radar and Cassini's infrared imager. This led some team members to suggest it might have been a transient feature. But during Cassini's flyby on August 21, 2014, the feature was again visible, and its appearance had changed during the 11 months since it was last seen.

Scientists on the radar team are confident that the feature is not an artifact, or flaw, in their data, which would have been one of the simplest explanations. They also do not see evidence that its appearance results from evaporation in the sea, as the overall shoreline of Ligeia Mare has not changed noticeably. The team has suggested the feature could be surface waves, rising bubbles, floating solids, solids suspended just below the surface, or perhaps something more exotic." That the seasons are slowly changing on Titan is probably contributing to the transient nature of this feature.

Are the World's Religions Ready For ET?

Science_afficionado writes: At the current rate of discovery, astronomers will have identified more than a million exoplanets by the year 2045. That means, if life is at all common in the Milky Way, astronomers could soon detect it. Realization that the nature of the debate about life on other worlds is about to fundamentally change, lead Vanderbilt astronomer David Weintraub to begin thinking seriously about how people will react to such a discovery. He realized that people's reactions will be heavily influenced by their religious beliefs, so he decided to find out what theologians and leaders from the world's major religions have to say about the matter. The result is a book titled Religions and Extraterrestrial Life, published by Springer this month. He discovered that from Baptists to Buddhists, from Catholics to Mormons, from Islam to the Anglican Communion, religious views on alien life differ widely.

upontheturtlesback writes: The Arducorder Mini, an Arduino-compatible pocket-sized handheld sensing tool and the next in line of open source science tricorder-like devices designed by Dr. Peter Jansen, is nearing completion. Where the previous models have included about a dozen sensors spanning atmospheric, electromagnetic, and spatial readings, an exciting video of the new prototype shows this model includes sensors for spectroscopy, low-resolution thermal imaging, and radiation sensing. The development is open with the project build logs and most recent source schematics, board layouts, and firmware available on github. This project is an entry in the Hack a Day Prize for a trip to space.

Ebola Has Made It To the United States

Medicine 455

An anonymous reader sends news that the CDC has confirmed the first case of Ebola diagnosed on U.S. soil. An unnamed patient at Texas Health Presbyterian Hospital of Dallas was placed in isolation while awaiting test results for the dreaded virus. Apparently, the patient had traveled recently to a West African country, where the disease is spreading, and later developed symptoms that suggested Ebola. A blood specimen from the patient was sent to Centers for Disease Control and Prevention in Atlanta, a testing process that can take 24 to 48 hours to confirm an Ebola infection — or not. The results came back about 3:32 p.m. In other Ebola news, outbreaks in Nigeria and Senegal appear to be completely contained.

New Research Casts Doubt On the "10,000 Hour Rule" of Expertise

First time accepted submitter Scroatzilla writes What makes someone rise to the top in music, games, sports, business, or science? This question is the subject of one of psychology's oldest debates. Malcolm Gladwell's '10,000 hours' rule probably isn't the answer. Recent research has demonstrated that deliberate practice, while undeniably important, is only one piece of the expertise puzzle—and not necessarily the biggest piece.

Statistician Creates Mathematical Model To Predict the Future of Game of Thrones

samzenpus posted 2 days ago | from the math-is-coming dept.

Math 125

KentuckyFC writes One way of predicting the future is to study data about events in the past and build a statistical model that generates the same pattern of data. Statisticians can then use the model to generate data about the future. Now one statistician has taken this art to new heights by predicting the content of the soon-to-be published novels in the Song of Ice and Fire series by George R R Martin. The existing five novels are the basis of the hit TV series Game of Thrones. Each chapter in the existing books is told from the point of view of one of the characters. So far, 24 characters have starred in this way. The statistical approach uses the distribution of characters in chapters in the first five books to predict the distribution in the forthcoming novels. The results suggest that several characters will not appear at all and also throw light on whether one important character is dead or not, following an ambiguous story line in the existing novels. However, the model also serves to highlight the shortcomings of purely statistical approaches. For example, it does not "know" that characters who have already been killed off are unlikely to appear in future chapters. Neither does it allow for new characters that might appear. Nevertheless, this statistical approach to literature could introduce the process of mathematical modelling to more people than any textbook.

Medical Records Worth More To Hackers Than Credit Cards

Privacy 78

HughPickens.com writes Reuters reports that your medical information, including names, birth dates, policy numbers, diagnosis codes and billing information, is worth 10 times more than your credit card number on the black market. Fraudsters use this data to create fake IDs to buy medical equipment or drugs that can be resold, or they combine a patient number with a false provider number and file made-up claims with insurers, according to experts who have investigated cyber attacks on healthcare organizations. Medical identity theft is often not immediately identified by a patient or their provider, giving criminals years to milk such credentials. That makes medical data more valuable than credit cards, which tend to be quickly canceled by banks once fraud is detected. Stolen health credentials can go for $10 each, about 10 or 20 times the value of a U.S. credit card number, says Don Jackson, director of threat intelligence at PhishLabs, a cyber crime protection company. He obtained the data by monitoring underground exchanges where hackers sell the information. Plus "healthcare providers and hospitals are just some of the easiest networks to break into," says Jeff Horne. "When I've looked at hospitals, and when I've talked to other people inside of a breach, they are using very old legacy systems — Windows systems that are 10 plus years old that have not seen a patch."

Study: An Evolutionary "Arms Race" Shaped the Human Genome

An anonymous reader writes "An evolutionary race between rival elements within the genomes of primates drove the evolution of complex regulatory networks that orchestrate the activity of genes in every cell of our bodies, reveals new research. The race was between mobile DNA sequences known as 'retrotransposons' (jumping genes) and the genes that have evolved to control them. Scientists at the University of California Santa Cruz, identified genes in humans that make repressor proteins to shut down specific jumping genes. "We have basically the same 20,000 protein-coding genes as a frog, yet our genome is much more complicated, with more layers of gene regulation. This study helps explain how that came about," said Sofie Salama, a research associate at the UC Santa Cruz Genomics Institute who led the study."

Scientists Seen As Competent But Not Trusted By Americans

cold fjord writes The Woodrow Wilson School reports, "If scientists want the public to trust their research suggestions, they may want to appear a bit 'warmer,' according to a new review published by Princeton University's Woodrow Wilson School of Public and International Affairs. The review, published in the Proceedings of the National Academy of Sciences (PNAS), shows that while Americans view scientists as competent, they are not entirely trusted. This may be because they are not perceived to be friendly or warm. In particular, Americans seem wary of researchers seeking grant funding and do not trust scientists pushing persuasive agendas. Instead, the public leans toward impartiality. 'Scientists have earned the respect of Americans but not necessarily their trust,' said lead author Susan Fiske, the Eugene Higgins Professor of Psychology and professor of public affairs. 'But this gap can be filled by showing concern for humanity and the environment. Rather than persuading, scientists may better serve citizens by discussing, teaching and sharing information to convey trustworthy intentions.'"
