Are Criminals Born Bad?

From Times Online:

The field of neurocriminology is reviving some controversial ideas. Can criminal urges really be blamed on the brain?

We are used to hearing talk of “the criminal mind”. In future we can expect to hear more about “the criminal brain”. Recent scientific research suggests that criminality may be a trait tha t some people are born with or acquire very early in life. It’s an unsettling thought: examine the prefrontal cortex in the brain of a gurgling infant and you may see the signs of a potential future murderer.

Happiest States: Hawaii Moves Into First Place

From Live Science:

If you needed an extra twist of the arm to set off on a Hawaii vacation, here it is: The big-wave state was the happiest place to live in 2009, according to a newly released national survey.

Topping the well-being list among all 50 states, Hawaii pulled ahead of the 2008 leader Utah. But Utah and its neighbors still have plenty to smile about. Nine of the top 10 well-being states reside in the Midwest and the West. The south didn't fare so well, taking seven of the 11 lowest well-being spots on the list.

Scientists Get Closer To Understanding Why We Age

Biologists have observed that people's cells often age at different rates.

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

From New Scientist:

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.)

King Tut's Mom And Dad ID'ed

From Live Science:

Candidates for King Tut's mother and father have been identified using DNA analyses from royal Egyptian mummies.

King Tutankhamun ruled from 1333 to 1324 B.C., during the period of ancient Egyptian history known as the New Kingdom.

Though he is possibly the most well-known of the Egyptian pharaohs, many mysteries still exist about the life, death and parentage of King Tut. But new DNA tests may have helped answer the question of what killed Tut, as well as exactly who his parents were.

From Technology Review:

A new protocol called fasp-AIR promises speedier mobile downloads.

Transfers of large amounts of data across the Internet to wireless devices suffer from a key problem: The Transmission Control Protocol (TCP) used to send and receive that data can be unnecessarily slow.

A company called Aspera has now announced an alternative protocol designed to accelerate wireless transfer speeds. Called fasp-AIR, it includes new proprietary approaches to addressing problems of data transfer that are unique to wireless communications. The original fasp protocol is already used to boost regular Internet transfers. It was used, for instance, to speed up the transfer of files from New Zealand to the U.S. during production of the movie Avatar.
