A gene variation that helps people live into their 90s and beyond also protects their memories and ability to think and learn new information, according to a study published in the December 26, 2006, issue of Neurology, the scientific journal of the American Academy of Neurology.
An innovative social marketing campaign called “Healthy Penis,” which used humorous cartoon strips to encourage gay and bisexual men in San Francisco to get checked for syphilis, was associated with an increase in syphilis tests, according to evaluations published in PLoS Medicine.

What can you see from a pencil? How many dimentions can you see from a pencil? As scientist figured out, there are 1 more dimentions for everything in our universe – time. However, this dimention will lead us to think about the endless universe.
[Updated February 15, 2007 to also include "Hunting behavior of Large Bioluminescent Squid (Video)"]
Tokyo (AP) – A Japanese research team has succeeded in filming a giant squid live – possibly for the first time – and says the elusive creatures may be more plentiful than previously believed, a researcher said Friday.
Imagine a car windshield that displays a map to your destination, military goggles with targets and instructions displayed right before a soldier’s eyes or a billboard that doubles as a window. Only in science fiction you say? Northwestern University researchers report that by combining organic and inorganic materials they have produced transparent, high-performance transistors that can be assembled inexpensively on both glass and plastics.
Instruments aboard a Japan Aerospace Exploration Agency satellite named Hinode, or “Sunrise,” are returning extraordinary new images of our sun. The international mission to study the forces that drive the violent, explosive power of the sun launched from Japan in September. Hinode is circling Earth in a polar flight path (a “sun-synchronous” orbit) that allows the spacecraft’s instruments to remain in continuous sunlight for nine months each year.
The giraffe’s elongated neck has long been used in textbooks as an illustration of evolution by natural selection, but this common example has received very little experimental attention…
To your left runs a high-voltage power cable that is worn, but still physically sound. To your right runs a cable that looks identical, but damaged insulation means the cable is vulnerable to a short. Can you tell the difference? Even most power companies don’t know the weak points in their electrical grids. And although lights get turned on after a storm, the long-term effects of hurricanes, landslides or wind storms lie unnoticed. Now a robot can roll along the miles of cable, performing a utilities’ equivalent of check-ups.
They are the celestial equivalent of sonograms. But their hazy outlines and ghostly features do not document the in-vivo development of a future taxpayer. Instead, they chronicle the exo-planetary comings-and-goings of some of Earth’s least known, most nomadic, and at times most impactful neighbors. They are radar echoes that are bounced off of asteroids. Scientists from NASA’s Jet Propulsion Laboratory and around the world rely on their ethereal images to tell some out-of-this-world tales of near-Earth objects.
The surge of baby boomers now entering their 60s means more drivers on the road who may be impaired by dementia or other cognitive impairments linked to aging. Researchers at the Alzheimer’s Disease Research Center (ADRC) of Washington University School of Medicine in St. Louis and elsewhere have developed a three-hour workshop that trains health care providers to identify potentially unsafe drivers with dementia and to encourage appropriate retirement from driving.
New research explains how movie theaters may increase profits by moving away from uniform pricing to variable pricing. The study is being published in an upcoming issue of the International Review of Law & Economics. Currently, consumers pay the same price for blockbusters and for flops, for a movie on the Fourth of July and for a movie on a rainy day in January, for a movie on Friday night and for a movie on Monday evening.
A new imaging molecule that can detect and map plaques and tangles in the brains of people with Alzheimer’s disease could eventually lead to earlier diagnosis of the devastating disease, researchers at the University of California, Los Angeles report in the Dec. 21, 2006, issue of the New England Journal of Medicine. The compound, developed by UCLA and called FDDNP, also holds promise as a research tool to evaluate new treatments for Alzheimer’s.
It has been known for over 50 years that moths can hear the ultrasonic hunting calls of their nocturnal predator, the bat. Moth ears are among the simplest in the insect world — they have only two or four vibration-sensitive neurons attached to a small eardrum. Previously, it was thought that these ears were only partially sensitive to the sound frequencies commonly used by bats, and it would seem likely that by using high ultrasound, bats would make their hunting calls inaudible to moths. However, as now reported by James Windmill and colleagues at the University of Bristol (UK), moths are not as deaf as they had previously been supposed to be.
Last Super Bowl, a TV commercial lauded the power of Requip (ropinirole), the first drug approved to treat restless leg syndrome, a condition whose signature feature is creepy-crawly leg sensations that interfere with sleep and rest in nearly 1 of every 10 adults. But if taken too long, the drug can actually backfire, causing symptoms to worsen, say doctors who specialize in treating the condition. They say that treatment that rotates through different types of medications may be needed for many patients.
Researchers from the Commerce Department’s National Institute of Standards and Technology (NIST) and four universities have made the first experimental observation of rare particles of light emitted during the radioactive decay of the neutron, a key building block of matter. This work confirms theoretical predictions of this type of decay of the neutron and sets the stage for a new class of tests of basic theories in particle physics.
A new study suggests biochemical changes associated with schizophrenia aren’t limited to the central nervous system and that the disease could have more encompassing effects throughout the body than previously thought. The findings, scheduled for publication in the January 2007 issue of the American Chemical Society’s Journal of Proteome Research, could lead to better diagnostic testing for the disease and could help explain why those afflicted with it are more prone to type II diabetes, cardiovascular diseases and other chronic health problems.
A link between obesity and the microbial communities living in our guts is suggested by new research at Washington University School of Medicine in St. Louis. The findings indicate that our gut microbes are biomarkers, mediators and potential therapeutic targets in the war against the worldwide obesity epidemic.
