Researchers use baker's yeast to gain insight into chromosome separation process

Researchers at the Stowers Institute for Medical Research used, ironically enough, the single-celled organism Saccharomyces cerevisiae -- commonly known as baker's yeast -- to gain new insight into the process by which chromosomes are physically segregated during cell division.

New computer chip models how neurons communicate with each other at synapses

For decades, scientists have dreamed of building computer systems that could replicate the human brain's talent for learning new tasks. MIT researchers have now taken a major step toward that goal by designing a computer chip that mimics how the brain's neurons adapt in response to new information. This phenomenon, known as plasticity, is believed to underlie many brain functions, including learning and memory.

Researchers identify how to design drugs to target specific brain areas

The future of drug design lies in developing therapies that can target specific cellular processes without causing adverse reactions in other areas of the nervous system. Scientists at the Universities of Bristol and Li-ge in Belgium have discovered how to design drugs to target specific areas of the brain.

X-ray crystallography identifies structure of apoA-I molecule

Using a sophisticated technique of x-ray crystallography, researchers Xiaohu Mei, PhD, and David Atkinson, PhD, from Boston University School of Medicine (BUSM) have for the first time obtained an "image" of the structure and the precise arrangement of the atoms in a truncated form of the apolipoprotein A-I (apoA-I) molecule.

Eliminating senescent cells could prevent or delay onset of age-related disorders

Researchers at Mayo Clinic have shown that eliminating cells that accumulate with age could prevent or delay the onset of age-related disorders and disabilities. The study, performed in mouse models, provides the first evidence that these "deadbeat" cells could contribute to aging and suggests a way to help people stay healthier as they age.

Australian researchers make a quantum leap in understanding key cell structures

Researchers in Australia and the UK have made a world first discovery that will provide the most accurate understanding to date of the structure and function of the most important energy converting protein, critical to the function of all organs and a cause of disease when malfunctioning.

NEP successfully inserts specific doses of anti-cancer gene into leukemia cells

For the first time, researchers have found a way to inject a precise dose of a gene therapy agent directly into a single living cell without a needle.

First successful quantification of membrane lipids in a living cell

Could controlling cell-membrane fat play a key role in turning off disease? Researchers at the University of Illinois at Chicago think so, and a biosensor they've created that measures membrane lipid levels may open up new pathways to disease treatment.

USDTL releases CordStat EtOH assay screens for newborn alcohol exposure in utero

United States Drug Testing Laboratories (USDTL), a reference laboratory specializing in alcohol and drugs of abuse testing, released a new assay testing umbilical cord for newborn alcohol exposure in utero on Monday, October 3, 2011.

Plausible way to circumvent drug resistance in breast cancer cells

Breast cancer cells that mutate to resist drug treatment survive by establishing tiny pumps on their surface that reject the drugs as they penetrate the cell membrane - making the cancer insensitive to chemotherapy drugs even after repeated use.

MDC researchers determine molecular structure of dynamin

Dr. Katja F-lber and Professor Oliver Daumke, structural biologists at the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch, together with researchers from Freie Universit-t (FU) Berlin, have determined the molecular structure of dynamin, a 'wire-puller' that mediates nutrient uptake into the cell.

Scientists investigate how rhythmic activity of nerve cells supports spatial navigation

Prof. Dr. Motoharu Yoshida and colleagues from Boston University investigated how the rhythmic activity of nerve cells supports spatial navigation.

Landmark discovery in rapid spread of PRL-3 oncoprotein associated aggressive cancers

Scientists at A*STAR's Institute of Molecular and Cell Biology (IMCB) have made a landmark discovery in the battle against the rapid spread of aggressive cancers associated with PRL-3 oncoprotein.

Zinc may act as tumor suppressor in commonist form of pancreatic cancer

The essential element zinc has been shown in a new study to be a likely tumor suppressor in the commonist form of pancreatic cancer, University of Maryland scientists report in the current issue of the journal Cancer Biology & Therapy.

Scientists discover key defense mechanism against C. difficile infection

Researchers have discovered a key mechanism used by intestinal cells to defend themselves against one of the world's most common hospital-acquired bacterial infections - a mechanism they think they can exploit to produce a therapy to protect against the effects of the antibiotic-resistant bacteria.
