Doctors Turn to Artificial Intelligence When They're Stumped

tcd004 tcd004 writes  |  about 3 months ago

tcd004 (134130) writes "Doctors are increasingly turning to big data and simple artificial intelligence when they can't find answers in traditional medical texts. Prodded by the new health care law to seek better ways to incorporate high tech into their everyday tasks, doctors are discovering the power of intelligent search engines and data mining. Artificial intelligence can be a tool to take full advantage of electronic medical records, transforming them from mere e-filing cabinets into full-fledged doctors’ aides that can deliver clinically relevant, high-quality data in real time. And tech giants are jumping on the opportunity. “Electronic health records [are] like large quarries where there’s lots of gold, and we’re just beginning to mine them,” said Dr. Eric Horvitz, who is the managing director of Microsoft Research and specializes in applying artificial intelligence in health care settings."

Fixing Google's Gender Gap Shouldn't Be So Hard

tcd004 tcd004 writes  |  about 3 months ago

tcd004 (134130) writes "Google just released data on the diversity of its employees for the first time. It's a big deal, and the numbers are bleak for both gender and ethnic diversity. But it shouldn't be so hard to find capable women and minorities to fill tech jobs, argues Vivek Wadhwa. In the 70's and 80's a third of all computer sciences grads were women. What happened? The brogrammer culture won out. Wadhwa has advice on how to fix it."

Temporary classrooms are bad for the environment, and worse for kids

tcd004 tcd004 writes  |  about 3 months ago

tcd004 (134130) writes "You've always suspected those trailer-type portable classrooms are no good, right? It turns out you’re right. Analysis of prefabricated classrooms in Washington shows the structures often don't allow for proper ventilation, leading to terrible air quality for kids. Students in temporary classrooms have higher rates of absenteeism than those in standard classrooms. And the energy-inneficient structures often become permanent, sucking on school energy bills for decades, and requiring more upkeep than permanent classrooms. What's needed are new designs for healthy, sustainable temporary classrooms."

As species decline, so do the scientists who name them

tcd004 tcd004 writes  |  about 4 months ago

tcd004 (134130) writes "Few sciences are more romantic than taxonomy. Imagine Darwin, perched over a nest of newly-discovered birds in the Galapagos, sketching away with a charcoal in his immortal journals. Yet Taxonomy is a dying science. DNA barcoding, which can identify species from tiny fragments of organic material, and other genetic sciences are pulling students away from the classical studies of anatomy and species classifications. As the biodiversity crisis wipes undiscovered species off the planet, so to go the scientists who count them."

At G.W. lab, toy cars fearlessly hurl themselves through the air for science

tcd004 tcd004 writes  |  about 4 months ago

tcd004 (134130) writes "Before you roll an autonomous car out on the street, you have to test. Robotics engineers at G.W. University's Autonomous Robotics & Perception Group test their autonomous car systems on a tiny racetrack, complete with jumps, a half-pipe and a loop-the-loop. The team, which specializes in computer localization technologies, has contributed to Google's Project Tango for a year. The ever-shrinking electronics that give computers, robots and cars the ability to understand 3-D space are laying the foundation for a revolution in autonomous applications."

Gamblers wager billions on unregulated Bitcoin betting sites

tcd004 tcd004 writes  |  about 5 months ago

tcd004 (134130) writes "By most estimates, more than half of global Bitcoin transactions are wagers on gambling sites. Just-Dice.com, where whales regularly make colossal bets, has handled more than $2 billion in wagers since it was founded in June 2013. All of this gambling happens in a currency that is largely unregulated, on websites set up on offshore servers, and right under the noses of officials who are unaware it exists."

Protecting the Solar System... From Us

tcd004 tcd004 writes  |  about a year and a half ago

tcd004 (134130) writes "Imagine this crazy scenario: A space vehicle we've sent to a distant planet to search for life touches down in an icy area. The heat from the spacecraft's internal power system warms the ice, and water forms below the landing gear of the craft. And on the landing gear is something found on every surface on planet Earth... bacteria. Lots of them. If those spore-forming bacteria found themselves in a moist environment with a temperature range they could tolerate, they might just make themselves at home and thrive and then, well... the extraterrestrial life that we'd been searching for might just turn out to be Earth life we introduced."

Bath Salts: Like a Fish Hook in your Brain

tcd004 tcd004 writes  |  about 2 years ago

tcd004 (134130) writes "PBS NewsHour published an investigation into Bath Salts, the sometimes legal, little understood street drug that has been linked to bizarre and violent behavior. The chemistry behind bath salts, it turns out, is as fascinating as the side effects. Tests show that the most common application of bath salts works in two-phases with a time-release mechanism. The drug first blasts the user with dopamine, but then limits the ability of the brain to soak it back up. And, researchers think, a unique "fish hook" shaped molecule means that the drug can get locked in, and take days, or even weeks to wear off— often, too late for users who are driven to extreme violence or suicide."

NASA: Our Climate Is Now More Extreme Than Any Other Time This Epoch

tcd004 tcd004 writes  |  about 2 years ago

tcd004 (134130) writes "Unlike climate studies which usually rely on computer projections and models looking out into the future, this one is slightly different. Set to be published Monday by the Proceedings of the National Academies of Sciences, NASA compared temperatures of the past 30 years against a baseline of the temperatures 30 years before then, and show there are far more weather events toward the extreme end of the average bell curve than there were before."

The Asteroid That Dances With Earth

tcd004 tcd004 writes  |  more than 3 years ago

tcd004 (134130) writes "An asteroid is caught in a synchronized orbit with the Earth, dancing back and forth relative to our planet as both circle the sun, a team of Canadian scientists has discovered. The object, which for now is dubbed 2010 TK7, is a "Trojan" asteroid, meaning that it is trapped in a delicate gravitational balance between a tug from the sun and an equal tug from the Earth. It's long been known that Jupiter, Neptune and Mars have Trojans orbiting alongside them, but this is the first time one has been found alongside our planet."

New Soyuz Launch Facility Gets Equator Boost

tcd004 tcd004 writes  |  more than 3 years ago

tcd004 (134130) writes "Russian and French teams are currently hard at work in French Guiana on the northern coast of South America, building the first Soyuz launch facility in the Western Hemisphere. Soyuz rockets normally carry 3,500 pound payloads into orbit, but from the French Guiana spaceport, the rocket will have an added benefit of being near the equator where the Earth's spin extremely fast. This extra boost allows it to deliver a 6,600 pound payload into orbit. The first launches are scheduled for October."

Drudge Generates More Traffic Than Social Media

tcd004 tcd004 writes  |  more than 3 years ago

tcd004 (134130) writes "A report released today by the Pew Research Center's Project for Excellence in Journalism shows that the Drudge Report is a far more important driver of online news traffic than Facebook or Twitter. In fact, for the top 25 news websites, Twitter barely registers as a source of traffic. The report hits on several other interesting findings about news behavior."

Solar Storm Nearly Wipes Out NASA's Messenger

tcd004 tcd004 writes  |  more than 3 years ago

tcd004 writes "There was a close call last week when an enormous coronal ejection nearly hit Mercury, and the orbiting Messenger spacecraft. Scientists at the Space Weather Laboratory flew into action, modeling the event to determine how close it had come to the spacecraft using data from the twin STEREO sun observers. The group use an animated model called WSA-ENLIL, named after a Sumerian lord of wind and storms. Enlil, who wears a crown of horns, is known for being a kind but also cruel god who sends forth disasters, including a great flood that wiped out humanity. Fortunately Messenger escaped Enlil's wrath."

Technology is Remaking Teenage Brains

tcd004 tcd004 writes  |  more than 3 years ago

tcd004 (134130) writes "The teen years are a critical "pruning" stage in the brain. Neural pathways that are needed are strengthened, and those that aren't are discarded. How is a twitter/facebook/texting/xbox lifestyle remaking the teen brain? DR. JAY GIEDD, a neuroscientist, National Institute of Mental Health is studying the affects of multitasking and constant communication on teens, and he thinks these influences may actually be building a better brain."

Old Facebook Apps Still Plunder Your Privacy

tcd004 tcd004 writes  |  more than 3 years ago

tcd004 (134130) writes "If you added the Youtube Facebook app prior to 2009, you're given YouTube free access to nearly all the data in your profile (as well as many of your friends). But if you install the same app today, it gets very limited access. Older versions of Facebook apps, it turns out, still have "grandfathered" access to data that the social networking service has restricted for new apps. If you're protective of your privacy, it might be a good idea to delete and reinstall any older apps in your profile."

Anon mining Gawker data leak to attack Governments

tcd004 tcd004 writes  |  more than 3 years ago

tcd004 (134130) writes "Documents obtained by the PBS NewsHour reveal a concerted effort to filter and verify U.S. and international government email accounts from the Gawker database leak. The group involved implores participants to keep the operation secret, because leaking their efforts "will only jeopordize the serious lulz fest about to hit the internet in the coming months." Agencies who have been breached allegedly include NASA, the U.S. Senate, the South African Judiciary, and others."

NASA strikes gold and water on the Moon

tcd004 tcd004 writes  |  more than 3 years ago

tcd004 (134130) writes "The PBS NewsHour reports: there is water on the moon ... along with a long list of other compounds, including, mercury, gold and silver. That's according to a more detailed analysis of the cold lunar soil near the moon's South Pole. The results were released as six papers by a large team of scientists in the journal, Science Thursday. The data comes from the October 2009 mission, when NASA slammed a booster rocket traveling nearly 6,000 miles per hour into the moon and blasted out a hole. Trailing close behind it was a second spacecraft, rigged with a spectrometer to study the lunar plume released by the blast. The mission is called LCROSS, for Lunar Crater Observer and Sensing Satellite."

Secret Drama Behind the Double Helix Revealed

tcd004 tcd004 writes  |  more than 3 years ago

tcd004 (134130) writes "Dozens of letters written by Nobel prize winner Frances Crick have just been released. The letters, which even Crick thought had been destoryed, reveal the intense, and sometimes playful competition among researchers to decode DNA in the 1960's. At one point, Watson and Crick were pulled off of DNA research because they incorporated works from a competing team at Kings College. Crick's letter to his rival (and friend) Maurice Wilkins read "Cheer up and take it from us that even if we kicked you in the pants it was between friends," he wrote. "We hope our burglary will at least produce a united front in your group!""

Would You Eat Genetically Modified Salmon?

tcd004 tcd004 writes  |  more than 3 years ago

tcd004 (134130) writes "The FDA is currently considering approval of the first mass-market, genetically modified animal, a super salmon. The engineered fish grows to full size in half the time, making it cheaper to raise and lessening it's environmental impact. But critics argue that the testing that has been done on the fish so far amounts to junk science, and there are unknown consequences if the fish escapes into the wild. Would you eat a hormone-enhanced fish?"

The 110MPG X-prize Car Was Built In Rural Virginia

tcd004 tcd004 writes  |  more than 3 years ago

tcd004 (134130) writes "Instead of using Detroit engineers or Silicon Valley bitheads, Virginia-based Edison2 relied on retired Formula 1 and Nascar engineers to build its entry for the X-prize. Relying on composite materials and titanium, the team assembled an ultra-lightweight car that provides all the comforts of a standard 4-passenger vehicle, but gets more than 100 mpg. The custom engineering goes all the way down to the car's lug nuts, which weigh less than 11 grams each. Amazingly, they expect a production version of the car should cost less than $20,000."
