The LED's Dark Secret - "The blue light-emitting diode, arguably the greatest optoelectronic advance of the past 25 years, harbors a dark secret: Crank up the current and its efficiencies will plummet. The problem is known as droop, and it's not only puzzling the brightest minds in the field, it's also threatening the future of the electric lighting industry..."
Roads that are designed to kill - "THREE YEARS AGO, I was driving in Atlanta early one morning when I saw a body on the road. It was a young female runner. I called 911 and then ran to her. She had a horrendous head injury but still had a heart beat. I started CPR, but her injuries were too severe. She died in my hands. I wrote a column in the Atlanta Journal-Constitution about what happened to the runner, and a flood of letters came in..."

Ford's Electric Cars Will Talk to the Power Grid, Pick Least Expensive Electricity Rates - "Smart recharging will be extremely important for electric cars and plug-in hybrids. It would be pretty disastrous if millions of plug-ins started recharging their batteries during peak demand, which is why auto makers are working on systems that would allow the cars to be programmed to not only charge when electricity is cheapest, but also to communicate directly with the power grid via smart meters..."
LIGO Announcement: New Limits on the Big Bang - "The first few moments of the Big Bang — according to most theories of how it actually worked — should have produced gravitational waves in the fabric of spacetime that are still rippling through all of space today. But by now they should be extremely weak, and no detector has had the capability to detect them at any plausible predicted level..."
Dark Energy's Demise? New Theory Doesn't Use the Force - " Dark energy, a mysterious force proposed more than a decade ago to explain why the universe is flying apart at an increasingly faster clip, is no longer necessary..."
Giant Robotic Cages to Roam Seas as Future Fish Farms? - " In the future, giant, autonomous fish farms may whir through the open ocean, mimicking the movements of wild schools or even allowing fish to forage "free range" before capturing them once again. Already scientists have constructed working remote control cages..."
ICE BEAR: How it Works - "Pairing its revolutionary Ice Bear energy storage module with a standard commercial air conditioner, Ice Energy delivers the industry's first hybrid cooling solution specifically developed to reduce air conditioning energy demand for small to mid-sized commercial businesses..."
Why Should Engineers and Scientists Be Worried About Color? - "At the core of good science and engineering is the careful and respectful treatment of data. We calibrate our instruments, scrutinize the algorithms we use to process the data, and study the behavior of the models we use to interpret the data or simulate the phenomena we may be observing. Surprisingly, this careful treatment of data often breaks down when we visualize our data..."

Mass Genome Crunching Rearranges the Foundation of Life - "A massive analysis of almost every bacterial genome sequenced to date suggests a new telling for the early story of life. One of the organismal tree's core branches — an offshoot of which later became the energy centers of plant and animal cells — appears to be a union of two other branches..."

Low-income kids report first sexual intercourse at 12 years old in new national study - "As a new mother herself, Brenda Lohman admits to being shocked by the results of a new study she co-authored. It found that among nearly 1,000 low-income families in three major cities, one in four children between the ages of 11 and 16 reported having sex, with their first sexual intercourse experience occurring at the average age of 12.77..."
How to Eat on a Dollar a Day - "The next post in the continuing frugal gastronomy series features a pair of schoolteacher-writers who gave themselves the toughest of all restrictions: All their food had to cost no more than $1 per day per person. Amazingly, if they invited guests over to eat, the guests' food had to be covered by the $1 allotment. You'd have to really like the guest, I suppose..."

They've worked out a new strategy that can enable a player to beat the game in terms of increasing their payoff. The strategy could have applications in optimizing gains in investments and other areas..."
Is This A Good Idea? Having your head transplanted onto another body? - "Having such a head transplant—or actually, from your point of view, a rest-of-the-body transplant—would have fairly obvious benefits. Why go to the trouble of Photoshopping the wrinkles from your Facebook portrait, traveling to an offshore rejuvenation clinic for human growth hormone therapy, or having yourself frozen at a cryonics lab, when you can just discard your worn cartilage, shrinking musculature and increasingly gunk-lined arteries and upgrade to a newer, better-equipped, higher-powered replacement?"

Ancient civilization - How the Airplanes Were - "Under his initiative, the artifact measuring 5.6 inches in length and 7.2 inches of wingspan gave rise to speculations about ancient Egyptians possessing aeronautics technology. Interestingly, this model was found to have a very advanced ‘pusher-glider' mechanism that can keep it air-borne at speed limits of 45 to 65 mph. Its assumed ability to carry a heavy weight during its flight was greatly attributed to its downward-pointing wings..." More info:
