New methods identify and manipulate 'newborn' cells in animal model of Parkinson's disease
When cells in the brain are lost through disease or injury, neighboring cells begin to divide and multiply, but only a few areas in the brain are able to produce new neurons.   view more (2008-09-04)

New nano device detects immune system cell signaling
Scientists have detected previously unnoticed chemical signals that individual cells in the immune system use to communicate with each other over short distances.   view more (2008-09-04)

Loss of sleep, even for a single night, increases inflammation in the body
Loss of sleep, even for a few short hours during the night, can prompt one's immune system to turn against healthy tissue and organs.   view more (2008-09-03)

Gene is likely cause of stroke-inducing vascular malformations
UCSF scientists have discovered that a gene controlling whether blood vessels differentiate into arteries or veins during embryonic development is linked to a vascular disorder in the brain that causes stroke.   view more (2008-09-03)

By manipulating the machinery used by our cells for quality control, researchers from the University of Pittsburgh have found a way to restore the function of cystic fibrosis (CF) airway cells.   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)

Jamaican lizards' shows of strength mark territory at dawn, dusk
What does Jack LaLanne have in common with a Jamaican lizard? Like the ageless fitness guru, the lizards greet each new day with vigorous push-ups. That's according to a new study showing that male Anolis lizards engage in impressive displays of reptilian strength -- push-ups, head bobs, and... view more (2008-08-28)

Iowa State University researcher shows proteins have controlled motions
Iowa State University researcher Robert Jernigan believes that his research shows proteins have controlled motions.   view more (2008-08-28)

Variation of normal protein could be key to resistance to common cancer drug
Researchers at the Moores Cancer Center at the University of California, San Diego (UC SD) in La Jolla have found evidence explaining why a common chemotherapy drug, cisplatin, may not always work for every cancer patient. They have shown that when a variant version of a key protein that normally... view more (2008-08-28)

Protein misprediction uncovered by new technique
A new bioinformatics tool is capable of identifying and correcting abnormal, incomplete and mispredicted protein annotations in public databases.   view more (2008-08-27)

Study reveals how blood flow force prevents clogged arteries
Machines on cell surfaces, mechanical and lifeless as bed springs, protect blood vessels by responding to blood flow force, according to research published today in the Journal of Cell Biology.   view more (2008-08-26)

Looking beyond the drug receptor for clues to drug effectiveness
Antipsychotic drugs that are widely used to treat schizophrenia and other problems may not work as scientists have assumed, according to findings from Duke University Medical Center researchers that could lead to changes in how these drugs are developed and prescribed.   view more (2008-08-26)

Discovery opens door for drugs to fight bird flu, other influenza epidemics
Researchers at Rutgers University and The University of Texas at Austin have reported a discovery that could help scientists develop drugs to fight the much-feared bird flu and other virulent strains of influenza.   view more (2008-08-26)

Chips are down as Manchester makes protein scanning breakthrough
Scientists at The University of Manchester have developed a new and fast method for making biological 'chips' - technology that could lead to quick testing for serious diseases, fast detection of MRSA infections and rapid discovery of new drugs.   view more (2008-08-25)

Dense tissue promotes aggressive cancers
New research may explain why breast cancer tends to be more aggressive in women with denser breast tissue. Breast cancer cells grown in dense, rigid surroundings step up their invasive activities, Vanderbilt-Ingram Cancer Center investigators report in the Sept. 9 issue of Current Biology.    view more (2008-08-25)

Anti-tumor effects are enhanced by inhibiting 2 pathways rather than 1
Two independent research groups have found that simultaneous inhibition of two signaling pathways resulted in substantially enhanced antitumor effects in mouse models of prostate and breast cancer. In an accompany commentary, Steven Grant, at Virginia Commonwealth University Health Science Center,... view more (2008-08-22)

Cancer therapy: A role for MAPK inhibitors combined with mTORC1 inhibitors
Nearly a decade ago, while it was being tested as an immunosuppressive agent to prevent organ rejection in transplant patients, the drug rapamycin was also discovered to have anti-tumor properties. Since then, several rapamycin analogs known as mTOR (mammalian target of rapamycin) inhibitors have... view more (2008-08-22)

Researchers discover how rheumatoid arthritis causes bone loss
Researchers have discovered key details of how rheumatoid arthritis (RA) destroys bone, according to a study published in the Aug. 22 edition of the Journal of Biological Chemistry.   view more (2008-08-21)

Study finds foul owls use feces to show they are in fine feather
Some years ago, within the Department of Conservation Biology of the Estación Biológica de Doñana (EBD-Consejo Superior de Investigaciones Científicas; Seville, Spain), a recently established group (colloquially named the Night Ecology Group) started to explore the... view more (2008-08-20)

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... view more (2008-08-20)

NYU scientists identify critical protein complex in formation of cell cilia
An international team led by NYU Cancer Institute have identified a protein complex that regulates the formation of cilia, which are found on virtually all mature human cells and are essential to normal cell function.   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)

Molecular sleuths track evolution through the ribosome
A new study of the ribosome, the cell's protein-building machinery, sheds light on the oldest branches of the evolutionary tree of life and suggests that differences in ribosomal structure between the three main branches of that tree are "molecular fossils" of the early evolution of... view more (2008-08-19)

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)

Experiments could lead to new treatments for neuroblastoma
Neuroblastoma is one of the most devastating diagnoses a child can receive. The cancer's victims average 2 years old when the disease is detected, most often by a parent feeling a lump in a child's abdomen. By then, the disease has often reached an advanced stage, and advanced neuroblastoma kills... view more (2008-08-18)
