A new transistor designed to mimic structures in the human brain could pave the way for increasingly efficient computer systems that "think" like humans, scientists say.

The transistor is the first to mimic a crucial process used by brain cells, or neurons, when the cells signal one another.

Scientists Shed Light On Supernova Origins

Type Ia supernovae are thought to result when a white dwarf star in a binary system accumulates enough matter from its larger companion. When the white dwarf reaches the critical Chandrasekhar mass, about 1.4 times the mass of our Sun, high internal density and temperature ignite a thermonuclear explosion. Because the masses of Type Ia supernovae are similar, their brightnesses are similar. Berkeley Lab

From The L.A. Times:

The so-called Type 1a supernovae are key to measuring celestial distances. Astronomers find evidence that they're formed by the collision of two white dwarfs.

German astronomers using a U.S. telescope have provided scientists with at least a partial answer to a vexing question: What is the origin of the so-called Type 1a supernovae, which are widely used as celestial mileage markers?

Type 1a supernovae are of special significance to astronomers because all are believed to have essentially the same intrinsic brightness, and because they can be observed from great distances. Thus, by comparing the brightness of any one of them to what it is expected to be, researchers can estimate its distance from Earth and thereby judge the distance of objects near it.

DARPA Wants To Build The Ultimate Language Traslator

Darpa Looks to Build Real-Life C3P0 -- The Danger Room

Right now, troops trying to listen in on enemy chatter rely on a convoluted process. They tune into insurgency radio frequencies, then hand the radio over to local interpreters, who translate the dialogues. It’s a sloppy process, prone to garbled words and missed phrases.

What troops really need is a machine that can pick out voices from the noise, understand and translate all kinds of different languages, and then identify the voice from a hit list of “wanted speakers.” In other words, a real-life version of Star Wars protocol droid C3PO, fluent “in over 6 million forms of communication.”

From Science Daily:

Science Daily (Feb. 16, 2010) — Physicists may have glimpsed a particle that is a leading candidate for mysterious dark matter but say conclusive evidence remains elusive.

A 9-year search from a unique observatory in an old iron mine 2,000 feet underground has yielded two possible detections of weakly interacting massive particles, or WIMPs. But physicists, who include two University of Florida researchers, say there is about a one in four chance that the detections were merely background noise -- meaning that a worldwide hunt involving at least two dozen different observatories and hundreds of scientists will continue.

Why People Fake Illness

From Live Science:

In 2008, a Baltimore woman named Dina Leone shared shocking news with her friends and family: she had been diagnosed with stomach cancer. She wrote blogs and Facebook notes, updating everyone on her treatment and progress. The 37-year-old mother of two received more than an outpouring of support and get-well cards; she also got money to help pay for her treatments and fulfill her dying wishes.

It was all very tragic – and it was also a hoax. Police investigated her claims and soon her story unraveled when the hospitals she claimed to have visited had no record of her. Leone eventually admitted that she had pretended to be sick for over three years. She was recently indicted on charges of theft and conspiracy.

But why would someone lie about having cancer?

Scientists Get Closer To Understanding Why We Age

Image Source / Corbis

From Time Magazine:

Time waits for no man, the old truism goes, but in recent years scientists have shown that it does seem to move more slowly for some. Molecular biologists have observed that people's cells often age at different rates, leading them to make a distinction between "chronological" and "biological age."

But the reason for the difference remains only vaguely understood. Environmental factors such as smoking, stress and regular exercise all seem to influence the rate at which our cells age. Now, for the first time, researchers have found a genetic link to cellular aging — a finding that suggests new treatments for a variety of age-related diseases and cancers.

In Brookhaven Collider, Scientists Briefly Break A Law Of Nature

HOT A computer rendition of 4-trillion-degree Celsius quark-gluon plasma created in a demonstration of what scientists suspect shaped cosmic history. Brookhaven National Laboratory

From The New York Times:

Physicists said Monday that they had whacked a tiny region of space with enough energy to briefly distort the laws of physics, providing the first laboratory demonstration of the kind of process that scientists suspect has shaped cosmic history.

The blow was delivered in the Relativistic Heavy Ion Collider, or RHIC, at the Brookhaven National Laboratory on Long Island, where, since 2000, physicists have been accelerating gold nuclei around a 2.4-mile underground ring to 99.995 percent of the speed of light and then colliding them in an effort to melt protons and neutrons and free their constituents — quarks and gluons. The goal has been a state of matter called a quark-gluon plasma, which theorists believe existed when the universe was only a microsecond old.

'Star Wars' Is A Mere Phantom Menace To Missiles

The US Missile Defense Agency (MDA) has finally shot down a moving missile with an airborne laser – but military experts say the system is not good enough for combat.

A liquid-fuelled rocket – thought to be a Scud-B, similar to those being developed by Iran and North Korea – was fired from a ship off the coast California on 11 February.

Within the next 20 seconds, the "airborne laser testbed" onboard a modified Boeing 747 locked-on to it with two low-powered tracking lasers, then a laser beam of several megawatts, to heat-damage the missile's skin. If such damage is done while booster rockets are still firing, the stresses caused by the acceleration can destroy the missile, as this clip of the test shows.

Special Ops Gunships To Get Pain-Inducing Weapons

1. An electron gun fires a particle beam through a vacuum tube wrapped with strong magnets.
2. As the beam meets the magnetic field, the electrons bunch up and gyrate, producing high-power microwaves at set frequencies.
3. Mirrors steer the microwaves through a window made of diamond. The gem is used for its resistance to heat and for its clarity.
4. The electron beam’s excess energy is deposited in the coils of a collector.

From Popular Mechanics:

Nonlethal energy-beam blasters that cause pain without killing their targets could finally find a home—inside special operations gunships. Here's how they work.

The Pentagon has been researching nonlethal pain rays since the mid-’90s, but finding a vehicle to carry them has proven to be a challenge. Researchers have mounted these microwave weapons—which repel people by heating water molecules just under the skin, reportedly without damaging tissue—on trucks, guard towers and Humvees, but the U.S. military has never deployed them for real-world use. (Using such weapons on civilians in Iraq or Afghanistan is not seen as a good way to win hearts and minds.)

Did 'Dark Stars' Spawn Supermassive Black Holes?

A massive dark star voraciously eating matter and dark matter until it is well over 100,000 times the mass of the sun (NASA/Ian O'Neill).

From Discover Magazine:

Approximately 200 million years after the Big Bang, the universe was a very different place.

For starters, there was no starlight as there were no stars. This period was known descriptively as the "Dark Ages." As there were no stars, only clouds of the most basic elements persisted, fogging up the cosmos.

Although it's believed the first stars (known as "Population III stars") were sparked when hydrogen and helium gases cooled enough to clump together, collapsing under gravity and initiating nuclear fusion in the star cores (thus generating heavier elements), there's another possibility.

The discovery may improve the variant's negative image (see "Yes or no"). It also suggests why the variant is common despite its debilitating effects in old age. Carriers of the variant may have an advantage earlier in life, allowing them to reproduce and pass on the variant before its negative effects kick in.
