The compounds were originally discovered in experiments with fruit flies, which use the same carbon dioxide-sensing machinery to send each other threat signals. Interestingly, fruit flies' favorite foods, ripe fruit, also give off carbon dioxide; an
Lulz Security, the hacker group that recently attacked the U.S. Senate, Sony and PBS, said on Twitter that its taken down the website for the U.S. Central Intelligence Agency.
Scientists atJohns Hopkins claim to have determined the proper dose levels needed to create positive change that persist for more than a year with the psychoactive substance in so-called "magic mushrooms."
A nearby galaxy that looks like a smiley face harbors a dark secret: It has twin supermassive black holes, not just one. This rare find could shed light on what happens when ginormous galaxies collide.
The x-Ar arm reimagines a Steadicam’s spring system to make arms and tools feel weightless, diminishing the risk of repetitive-stress injuries without motors, batteries or external power.
Sunspots may be going into hibernation, a phenomenon unseen since the 17th century that could lead to cooler global temperatures, scientists said Tuesday.
Japan’s “T2K,” one of our favorite neutrino experiments (we’re keen on several), might have just cracked the mystery of why matter triumphed over antimatter after the Big Bang (they should have canceled each other out).
At TEDxMaastricht, Daniel Kraft offers a fast-paced look at the next few years of innovations in medicine, powered by new tools, tests and apps that bring diagnostic information right to the patient's bedside.
the age-old scratch test could be used to determine a material's toughness, or how well it resists fracturing after a small crack has already formed. The answer: The scratch test is indeed measuring crack resistance rather than strength and is valid
Andrew and his collaborators, however, found that the gel acts as a support structure through which cells can migrate and potentially reattach themselves to the nervous system. “The material provides a temporary scaffold on which new cells can grow a
Airbus has seen the future, and it's spacious, sunlit and full of interactive screens. Oh, and cocktails will be served in the virtual bar, assuming someone isn’t playing 18 holes in there.
Doctors generally reserve stem-cell therapy, which draws on those cells’ unique ability to regenerate and form into nearly any tissue, for patients with major medical problems, such as cancer and spinal-cord injuries.
Puerto Rico’s Arecibo Observatory will soon be the world’s largest radio telescope no more. After years of planning, China has broken ground on the Five-hundred-meter Aperture Spherical radio Telescope (FAST)
Today in things that may leave you scratching your head: the SWITL, the robotic hand that can pick up, move, and put down sol-gel materials without altering their shape or arrangement in the least.
How does one build a dinosaur? There are plenty of spare dinosaur parts laying around our modern world from which to build a dinosaur. We just need to find the right ones.
Someday, our cars will all be connected to each other, sharing traffic information, connecting us into “road trains,” and swapping position info so that collisions become a thing of the un-wired past.
According to a study released Monday by the Environmental Working Group, the best defense against the harmful effects of the sun's rays is a thick coating of human blood.
A mathematical analysis of golf ball trajectories along a flat gradient reveals a new and simple strategy for judging the perfect putt

oeing had just lost out to rival aerospace firm Northrop Grumman in a contest to develop a so-called “Unmanned Combat Air System” for the Navy, capable of taking off from, and landing on, aircraft carriers. That contest, known by its acronym N-UCAS —
In the Japanese study, which also appears in the current issue of Science, a team led by researchers at Tohoku University added cobalt to titanium dioxide, a nonmagnetic semiconductor, to create a new material that, like a chameleon, can transform fr
Researchers at Harvard Medical School and Massachusetts General Hospital built a living laser partly to study interactions between electronic and biological systems, and partly out of sheer curiosity.
Plenty of gadgets we take for granted come to us via the space program — GPS, cordless tools, the Fisher space pen. But NASA doesn’t always have to reinvent the wheel; sometimes off-the-shelf technology can serve the space agency just as well.
The days of rummaging for your cellphone may be over. Bluetooth-enabled timepieces now pull all your phone alerts right to your wrist. Eventually, these watches will communicate directly with the Web and serve as mobile hotspots on their own.
Silly Putty is pretty much the best non-Newtonian viscoelastic liquid we can think of--it stretches, it bounces, it transfers ink, it's reminiscent of mussel fibers, and it can be broken with a sharp blow.

Spanish police said Friday they had nabbed three hackers from vigilante group Anonymous for online attacks on Sony PlayStation and the governments of Egypt, Libya and Iran among others.
The ability to store electrical energy in an efficient and light weight form has the promise to solve many critical social problems. The last few months have led me to wonder whether we might not be betting on the wrong technology.
US transport authorities announced Friday the sacking of more than 30 staff at Honolulu International Airport for failing to screen baggage properly for explosives.
