From Science Daily:

ScienceDaily (Feb. 5, 2010) — Ancient human teeth are telling secrets that may relate to modern-day health: Some stressful events that occurred early in development are linked to shorter life spans.

"Prehistoric remains are providing strong, physical evidence that people who acquired tooth enamel defects while in the womb or early childhood tended to die earlier, even if they survived to adulthood," says Emory University anthropologist George Armelagos.

Bees See Your Face As A Strange Flower

From Live Science:

Bees can learn to recognize human faces, or at least face-like patterns, a new study suggests.

Rather than specifically recognizing people, these nectar-feeding creatures view us as "strange flowers," the researchers say. And while they might not be able to identify individual humans, they can learn to distinguish features that are arranged to look like faces.

The results suggest that, even with their tiny brains, insects can handle image analysis. The researchers say that if humans want to design automatic facial recognition systems, we could learn a lot by using the bees' approach to face recognition.

From Popular Mechanics:

A new Iranian missile and the Pentagon's funding illustrate the importance, and the vulnerabilities, of helicopters in modern battlefields.

Call it a case of defense-press diplomacy: An Iranian colonel this week spoke publicly about a "special weapon" that was tailor-made to destroy U.S. Apache attack helicopters. The government-run Iranian news agency also released images of the shoulder-fired surface-to-air missile.

Great (and Not So Great) Spaced Out Super Bowl Ads

From Discovery News:

As the Super Bowl weekend begins, excitement (or dread) is building for the infamous Super Bowl commercials that will grace our screens at half time. I'm hoping there might be one or two space-themed ads.

Last year, the tire company Bridgestone knocked it out of the park with astronauts dancing to House of Pain's hit tune "Jump Around" on an alien planet/moon only to return to their rover to find its tires had been stolen by thieving aliens.

Unfortunately, the Bridgestone effort is more of an exception than a rule, because some of the other space-themed Super Bowl ads can be on the wrong side of "cheesy" (but don't worry, I doubt there will be any ill effects from bad-ad exposure).

Wind Power Growth Limited By Radar Conflicts

From CNET:

WASHINGTON--The most well-known obstacles to installing wind turbines are complaints over their visual impact and the potential for bird and bat deaths. But conflict with radar systems have derailed over 9,000 megawatts worth of wind capacity--nearly as much as was installed in the U.S. last year.

"We're not going to put up more wind (in many locations) without conflict because radar systems and wind systems love exactly the same terrain...which is where the wind is at," said Gary Seifert, a program manager for renewable energy technologies at the Idaho National Laboratories, during a presentation at the RETECH conference here on Thursday.

What Really Motivates Sperm

From Live Science:

In high-school health class films, sperm cells are shown zooming around with quick flicks of their tails, but they only jump into action when they are in the right chemical conditions – usually that's in the female reproductive tract. Researchers have now figured out the precise chemical switch that turns on the sperm's motors, which could lead to the development of new treatments for infertility.

Scientists have long known that sperm's activity level depends on the internal pH of the sperm cell —a measure of how acidic or alkaline a substance is. They start out with acidic insides when in the male reproductive tract, but once they enter the female tract, their internal environment becomes alkaline and off they zoom toward the egg.

From New Scientist:

JUST one tablet of paracetamol (acetaminophen) could help save earthquake survivors who otherwise risk dying from kidney failure after rescue. Experiments in rats have shown that the drug prevents "crush syndrome", or rhabdomyolysis, in which muscle debris from crushed limbs floods the kidneys soon after the limb is freed from rubble, causing them to fail.

"When you release the pressure on muscle through rescue, debris goes to the kidney. It's like a chain reaction, and acetaminophen blocks it," says Olivier Boutaud of Vanderbilt University in Nashville, Tennessee, and head of the research team.

From Technology Review:

An earlier measure of treatment could improve patients' prognosis.

When it comes to aggressive cancers, in the brain or lung for example, oncologists know that the sooner they can determine whether a treatment is unsuccessful, the sooner they can reevaluate and, if necessary, prescribe a new course of action. But typically, it takes two months or more to do the before-and-after comparisons that help determine whether a tumor is shrinking. Now an Israeli company called Aposense says it may have found a way to drastically speed up the process: an imaging marker that, when used with PET scans, indicates the presence of dying cells.

Suspected Asteroid Collision Leaves Odd X-Pattern Of Trailing Debris

This is a NASA Hubble Space Telescope picture a comet-like object called P/2010 A2, which was first discovered by the LINEAR (Lincoln Near-Earth Asteroid Research program) sky survey on January 6. The object appears so unusual in ground-based telescopic images that discretionary time on Hubble was used to take a close-up look. This picture, from the January 29 observation, shows a bizarre X-pattern of filamentary structures near the point-like nucleus of the object and trailing streamers of dust. The inset picture shows a complex structure that suggests the object is not a comet but instead the product of a head-on collision between two asteroids traveling five times faster than a rifle bullet (5 kilometers per second).

The Pursuit Of Intelligence In Computer Science

What actually constitutes an objective pattern of cognition in machines that we will recognize as intelligent is extremely vague and constantly being rewritten. Steve Dunning/Getty Images

From Discovery News:

We can’t give machines intelligence until we can figure out what roles creativity, inspiration and curiosity should play.

Since the dawn of high tech electronics and robotics, we’ve heard an awful lot about artificial intelligence and countless tales about how it may just decide to enslave us all one of these days, or fuse with humanity into an unrecognizable homunculus of men, women, children and machines as in the end of Isaac Asimov’s classic short story The Last Question, which is probably my favorite science fiction tale for it’s amazing scope and it’s bizarre climax. But when we actually drill down to the actual requirements for making machines endowed with the kind of computing abilities we’d call intelligence, we’ll find that the definition of what actually constitutes an objective pattern of cognition we will recognize as intelligent is extremely vague and constantly being rewritten.
