Certain Female Fish Have Special Mating Preference
A biologist at Washington University in St. Louis has shown that for some fish species, females prefer males with larger sexual organs, and actually choose them for mating. That does not exclude males with an average-sized sex organ, called a gonopodium. These fish out-compete the larger-endowed males in a predator-laden environment because they have a faster burst speed than the males with larger genitalia -- their endowment slows them down, making them easy prey. Microgravity Tower Will Offer Reduced-gravity Environment For Wide Ran
A new microgravity tower will allow scientists to study, in a reduced-gravity environment, many diverse phenomena in many fields including nanomaterials, new materials, fire-safety, metallurgy, biotechnology and combustion. The tower works by placing the experimental material inside a "drop capsule"that, when dropped from the top of the tower, allows the experiment to be in free fall (or zero gravity) for two seconds, enough time for scientists to make crucial observations about the phenomena being studied. Folates More Effective In Limiting Alzheimer's Disease Risk Than Antio
Adults who eat the daily recommended allowance of folates -- B-vitamin nutrients found in oranges, legumes, leafy green vegetables and folic acid supplements -- significantly reduce their risk of developing Alzheimer's disease, according to results from a long-term National Institute on Aging study of diet and brain aging. Superfluid Helium-4 Whistles Just The Right Tune
University of California, Berkeley, physicists can now tune in to and hear normally inaudible quantum vibrations, called quantum whistles, enabling them to build very sensitive detectors of rotation or very precise gyroscopes. Molecular Fingerprint Of Breast-cancer Drug Resistance Can Predict Res
There is a new way of predicting which patients will respond well to treatment with a common chemotherapy drug used in breast cancer. Researchers have identified two genes that could identify which cells would be resistant and which would respond to docetaxel. World Trade Center (WTC) Health Studies and Information on Health Serv
Descriptions of health studies by the New York State Department of Health, which "is actively involved in assessing health risks among individuals exposed to the smoke and debris from the World Trade Center"as a result of the September 11, 2001, attacks. Also includes annotated links to health services for residents of lower Manhattan, responders, and health care providers. From the New York State Department of Health. Dieting Danger: Female Athletes Limiting Calories More Likely To Get S
Female college athletes on low-calorie diets could be putting themselves at risk for stress fractures, according to new Saint Louis University research published in this month's American Journal of Sports Medicine. Difference Between Fish And Humans: Century-old Developmental Question
Embryologists have helped solve an evolutionary riddle that has been puzzling scientists for over a century. They have identified a key mechanism in the initial stages of an embryo's development that helps differentiate more highly evolved species, including humans, from less evolved species, such as fish. Building a Better Storm Center
Designing a new home for NOAA -- the satellite guys -- sets off a hurricane-force fight between the geeks and the government's star architect. By Andrew Blum from Wired magazine. United Nations Office on Drugs and Crime, Country Office Afghanistan:
Reports on topics such as opium poppy production (annual back to 2000), a farmers' intentions survey, and an assessment of drug use in Kabul. Also includes links to a fact sheet about drugs and crime in Afghanistan and to related information. From the United Nations Office on Drugs and Crime (UNODC).
