Ask permission to use newborn data, parents say
More than three-quarters of parents would be willing to permit the use of their children's newborn screening samples for research purposes if their permission were obtained beforehand, a University of Michigan survey shows. view more (2009-07-16)
A low expression of MX2 gene exists in the white blood cells of narcoleptics
The first report to identify the biological markers of narcolepsy using gene expression in white blood cells finds that the MX2 gene, which is relevant to the immune system, is significantly less expressed in narcoleptics compared with normal subjects. view more (2007-08-01)
Inactivity of proteins behind longer shelf life when freezing
Frozen biological material, for example food, can be kept for a long time without perishing. A study by researchers at the University of Gothenburg, Sweden, is close to providing answers as to why. view more (2009-03-03)
Scientists Conduct Shark Survey off U.S. East Coast
Sandbar, dusky and tiger sharks are among dozens of shark species living in the coastal waters off the U.S. East Coast. Little is known about many of the species, but a survey begun nearly 25 years ago is helping scientists and fishery resource managers to monitor shark populations and their role in marine ecosystems. view more (2009-08-14)
Human reproductive rates follow biological scaling rules
In nations with high per capita energy consumption, women have fewer children. This phenomenon is an unexpected consequence of the biological scaling relationship between metabolism and reproductive rate: larger species of mammals have higher metabolism but lower birth rates. In the April 2003 issue of Ecology Letters, Moses and Brown show that... view more... (2003-04-08)
New research challenges advice that men should abstain from sex before fertility treatment
Madrid, Spain: New research by Israeli fertility experts has challenged current medical opinion, which holds that refraining from sex for up to a week at least is beneficial for men prior to undergoing some types of fertility treatment. Doctors and scientists from Soroka University and Ben-Gurion University of the Negev, Beer-Sheva, tested over... view more... (2003-06-27)
Further gene mutations linked to autism risk
Pieces in the complex autism inheritance puzzle are emerging in the latest study from a research team including geneticists from the University of Pennsylvania School of Medicine and The Children's Hospital of Philadelphia (CHOP). view more (2009-06-29)
Laser Goes Tubing for Faster Body-Fluid Tests
University of Rochester researchers announce in the current issue of Applied Optics a technique that in 60 seconds or less measures multiple chemicals in body fluids, using a laser, white light, and a reflective tube. view more (2007-04-03)
Comprehensive genetic study paves way for new blood-pressure medicines
Eight previously unknown genes that affect blood pressure were recently identified in a comprehensive international study comprising 34,433 Europeans. view more (2009-05-11)
Theory of oscillations may explain biological mysteries
New mathematical studies of the interactions between oscillating biological populations may shed light on some of the toughest questions in ecology, including the number and types of species in an ecosystem, according to an article in the December 2006 issue of BioScience. view more (2006-12-04)
Sniffing out chloride
When industrial plants are wrecked, they often leave behind a site with contaminated soil. If it was a metalworking plant, a textile production or dry-cleaning facility, a paint manufacturing or an animal waste processing plant, the soil is often contaminated with chlorine-based solvents. In order to bring the concentration back down to below the... view more... (2002-09-09)
Large-scale genomics project will hunt genes behind common childhood diseases
The Children's Hospital of Philadelphia is launching an ambitious program to identify the genes responsible for common childhood diseases. view more (2006-06-07)
Research casts doubt on controversial scientific theory
Scientists at the University of Sheffield have cast doubt on the validity of the controversial theory of biological cold fusion, the principle sometimes used to lend credence to the practice of selling silicon tablets to strengthen bones, on the assumption that the body will turn the silicon into calcium. view more (2003-05-07)
AIDS discovered in wild chimpanzees
Although the AIDS virus (HIV-1) entered the human population through chimpanzees, scientists have long believed that chimpanzees don't develop AIDS. view more (2009-07-23)
Mars meteorite similar to bacteria-etched earth rocks
A new study of a meteorite that originated from Mars has revealed a series of microscopic tunnels that are similar in size, shape and distribution to tracks left on Earth rocks by feeding bacteria. view more (2006-03-24)
Safer Method for Large-Scale Malaria Screening Developed
Researchers at the Johns Hopkins Bloomberg School of Public Health's Malaria Research Institute have developed a new test for detecting the malaria parasite in human urine and saliva. view more (2006-11-21)
UW astronomer hits cosmic paydirt with Stardust
Scientists at the Johnson Space Center in Houston were excited and awed Tuesday by what they saw when the sample-return canister from the Stardust spacecraft was opened. view more (2006-01-19)
Scientists uncover further steps leading to celiac disease
Scientists who last year identified a new genetic risk factor for coeliac disease, have, following continued research, discovered an additional seven gene regions implicated in causing the condition. view more (2008-03-03)
Terahertz imaging may reduce breast cancer surgeries
A promising new technique to ensure complete tumor removal at breast cancer excision is introduced in the May issue of Radiology. view more (2006-04-26)
Fossil steroids record the advent of earliest known animals
Using compounds preserved in sedimentary rocks more than 635 million years old, researchers have found some of the earliest evidence for the existence of animals. view more (2009-02-05)
