PET's Imaging Power May Be Best Indicator For Determining Which Patien
Positron emission tomography (PET) imaging--with the radiotracer fluorodeoxyglucose (FDG)--is a promising tool in detecting Alzheimer's disease in patients who have mild cognitive impairment (MCI), according to a study reported in the October issue of the Society of Nuclear Medicine's Journal of Nuclear Medicine. Increased Availability Of Genetically Altered Mice To Aid Studies Of H
The National Institutes of Health will provide $4.8 million to establish and support a repository for its Knockout Mouse Project. This award is the final component of a more than $50 million initiative to increase the availability of genetically altered mice and related materials. University Of Manchester Develops Vision Chip For New Generation Of 'H
The University of Manchester is to help develop a new generation of robots with 'human' instincts. The REVERB project, which involves BAE Systems and a number of other leading UK Universities, is aimed at developing new technologies which will enable robots to respond to events and multi-task in similar ways to humans and animals. As part of the project The University of Manchester will develop a state of the art Vision Chip. Say Hello to the Goodbye Weapon
A new radiation weapon that produces the "Goodbye effect" -- making victims run like crazy -- has been certified for use in Iraq. It feels like the skin is being ripped from your face, but the military says it's perfectly safe. A special "Freedom of Information" report by David Hambling. Separating Wheat From Chaff In Plant Genomes
In a new study, Joseph Bedell and his colleagues describe a way to filter away repetitive elements when sequencing the genome of sorghum (Sorghum bicolor), a staple crop in much of the developing world because of its resilience in arid climates. Peace and Privacy in the Pacific
The Japanese have no native word for "privacy" -- but a government crackdown on peace activists is quickly expanding their vocabulary. Commentary by Jennifer Granick. Rats Develop 'Illusion Of Control': Experience Sculpts Brain Circuitry
It's long been known that experiencing control over a stressor immunizes a rat from developing a depression-like syndrome when it later encounters stressors that it can't control. Now, scientists have unraveled the workings of the brain circuitry that inoculates against such hard knocks -- the circuitry of resilience. Control not only activated the brain's executive hub, the prefrontal cortex, but also altered it so that it later activated even when the stressor was not controllable. Liquid Condoms Coming?
China gives new high-tech prophylactic a go. Plus: Take your sex toys with you over the holidays. From the Wired News blog Sex Drive Daily. NASA Finds Lightning Clears Safe Zone In Earth's Radiation Belt
Lightning in clouds, only a few miles above the ground, clears a safe zone in the radiation belts thousands of miles above the Earth, according to NASA-funded researchers. The unexpected result resolves a forty-year-old debate as to how the safe zone is formed, and it illuminates how the region is cleared after it is filled with radiation during magnetic storms. Galapagos Hawk's Evolutionary History Illuminated
Scientists used DNA sequences from feather lice to study how island populations of their host, the Galápagos Hawk might have colonized the Galápagos islands, home to the endangered and declining raptor. The study focuses on genes from three parasite species restricted to the Galápagos Hawk.
