Gene enhancer in evolution of human opposable thumb
Scientists have discovered a gene enhancer, known as HACNS1, that may have contributed to the evolution of the uniquely opposable human thumb, and possibly also modifications in the ankle or foot that allow humans to walk on two legs. view more (2008-09-05)
International team reveals first prognosticator of survival in aggressive cancer
The tumor suppressor gene pRb2/p130 may provide the first independent prognostic biomarker in cases of soft tissue sarcoma (STS). view more (2008-09-04)
Trichoplax genome sequenced -- 'rosetta stone' for understanding evolution
Yale molecular and evolutionary biologists in collaboration with Department of Energy scientists produced the full genome sequence of Trichoplax, one of nature's most primitive multicellular organisms, providing a new insight into the evolution of all higher animals. view more (2008-09-04)
Antidepressants need new nerve cells to be effective, researchers find
Researchers at UT Southwestern Medical Center have discovered in mice that the brain must create new nerve cells for either exercise or antidepressants to reduce depression-like behavior. view more (2008-08-29)
Study shows more genes are controlled by biological clocks
The tick-tock of your biological clock may have just gotten a little louder. Researchers at the University of Georgia report that the number of genes under control of in living things than suspected only a few years ago. view more (2008-08-29)
New concepts in contraception
Latest research into dual-purpose contraceptives and non-hormonal contraception will be presented tomorrow at a major scientific conference in Melbourne. view more (2008-08-27)
Making 'good' fat from muscle and vice versa
A surprise discovery -- that calorie-burning brown fat can be produced experimentally from muscle precursor cells in mice -- raises the prospect of new ways to fight obesity and overweight, say scientists from Dana-Farber Cancer Institute. view more (2008-08-21)
Rice lab finds molecular clues to Wilson disease
Using a combination of computer simulations and cutting-edge lab experiments, physical biochemists at Rice University have discovered how a small genetic mutation -- which is known to cause Wilson disease -- subtly changes the structure of a large, complex protein that the body uses to keep copper from building up to toxic levels. view more (2008-08-20)
Study shows how daughter is different from mother
The mother-daughter relationship can be difficult to understand. Why are the two so different? Now a Northwestern University study shows how this happens. In yeast cells, that is. view more (2008-08-19)
Researchers uncover attack mechanism of illness-inducing bacterium found in shellfish
An infectious ocean-dwelling bacterium found in oysters and other shellfish kills its host's cells by causing them to burst, providing the invader with a nutrient-rich meal, researchers at UT Southwestern Medical Center have found. view more (2008-08-19)
Cancer signatures uncovered
A new systematic analysis of the relationship between the neoplastic and developmental transcriptome provides an outline of trends in cancer gene expression. view more (2008-08-18)
By amplifying cell death signals, scientists make precancerous cells self-destruct
When a cell begins to multiply in a dangerously abnormal way, a series of death signals trigger it to self-destruct before it turns cancerous. Now, in research to appear in the August 15 issue of Genes & Development, Rockefeller University scientists have figured out a way in mice to amplify the signals that tell these precancerous cells to... view more...

MSU's discovery of plant protein holds promise for biofuel production
Scientists at Michigan State University have identified a new protein necessary for chloroplast development. The discovery could ultimately lead to plant varieties tailored specifically for biofuel production. view more (2008-08-18)
Model for Angelman syndrome developed by University of Texas at Austin biologists
A model for studying the genetics of Angelman syndrome, a neurological disorder that causes mental retardation and other symptoms in one out of 15,000 births, has been developed by biologists at The University of Texas at Austin. view more (2008-08-15)
Tiny molecule helps control blood-vessel development, researchers find
The development and repair of heart tissue and blood vessels is intimately tied to a tiny piece of ribonucleic acid (RNA) that is found nowhere else in the body, researchers at UT Southwestern Medical Center have found. view more (2008-08-13)
Monash researchers uncover cancer survival secrets
A team of Monash University researchers has uncovered the role of a family of enzymes in the mutation of benign or less aggressive tumours into more aggressive, potentially fatal, cancers in the human body. view more (2008-08-12)
New step forward in search for solution to infection puzzle
Scientists at the University of York have helped to reveal more about the way bacteria can attach to human tissues. view more (2008-08-07)
VCU Massey Cancer Center and VCU Institute of Molecular Medicine Researchers Publish Findings of a New Chemoprevention Gene Therapy That Kills Pancreatic Cancer Cells
Researchers at the Virginia Commonwealth University Massey Cancer Center and the VCU Institute of Molecular Medicine have published findings that implicate a new chemoprevention gene therapy (CGT) for preventing and treating pancreatic cancer, one of the most lethal and treatment-resistant forms of cancer. view more (2008-08-06)
Human brains pay a price for being big
Metabolic changes responsible for the evolution of our unique cognitive abilities indicate that the brain may have been pushed to the limit of its capabilities. Research published today in BioMed Central's open access journal Genome Biology adds weight to the theory that schizophrenia is a costly by-product of human brain evolution. view more (2008-08-05)
New study of gene evolution could lead to better understanding of neurodegenerative disease
Genetic evolution is strongly shaped by genes' efforts to prevent or tolerate errors in the production of proteins, scientists at The University of Texas at Austin and Harvard University have found. view more (2008-07-25)
