Towards the mechanism of cell respiration
Researchers at the Institute of Biotechnology of the University of Helsinki have for the first time identified an internal electron transfer reaction that initiates the proton pump mechanism of the respiratory enzyme.   view more (2006-04-06)

Researchers uncover E. coli's defense mechanism
The pathogenic forms of E. coli and Salmonella are usually transmitted to humans through undercooked meat, unwashed vegetables and cross contamination from surfaces on which these foods were prepared.   view more (2005-09-29)

The key of epilepsy can be in LGI1/Epitempina gene
Researchers of the Hospital of San Sebastian and the Biomedicine Institute of Valencia have discovered the genetic basis of hereditary epilepsy. The work leaded by the researchers Adolfo Lopez de Munain and Jordi Perez Tur has analysed the effect of the gene called LGI1/Epitempina. Temporal lateral... view more (2002-05-07)

TAKE CARE - YOUR CAMPING STOVE COULD SERIOUSLY DAMAGE YOUR HEALTH
Inadequate instructions on how to change gas canisters on camping stoves is resulting in unnecessary injuries, write Adrian Richards and colleagues from the Odstock Centre for Burns, Plastic and Maxillofacial Surgery at Salisbury District General Hospital in this week's BMJ. Based on experiences... view more (1999-02-26)

Mystery of ancient astronomical calculator unveiled
An international team has unravelled the secrets of a 2,000-year-old computer which could transform the way we think about the ancient world.   view more (2006-11-30)

Is sleep 'hard-wired' into the brain?
Falling asleep is usually thought of as something we can control ourselves as part of our behaviour patterns. In a new article in the December Journal of the Royal Society of Medicine, Dr Bidi Evans argues that waking and sleeping is actually controlled by a physical mechanism that is 'hard-wired'... view more (2002-11-25)

New stem-cell findings can help the body to cure itself
Researchers at Karolinska Institutet have identified an important mechanism that regulates how many new cells are produced by each intestinal stem cell. The study is published in the latest issue of the prestigious scientific journal, Cell.   view more (2006-06-16)

New insights into neural tube defects
Environmental and genetic factors lead to neural tube defects in 1 in every 1,000 births and cause 1 in 20 of every spontaneous abortion. One cause of these defects is the failure of cells within the neural tube to migrate to the middle of the developing neural tube.   view more (2006-01-12)

A new explanation for evolutionary changes in genetic sex-determination systems
In animals with separate sexes, embryos commit to becoming male or female at an early stage. Often this key decision is made by sex determination genes on the sex chromosomes. The genes involved in sexual development have changed remarkably little during evolution. In contrast, the sex... view more (2007-10-22)

New study shows that bacteria can communicate through the air
This month, Journal of Applied Microbiology publishes a ground-breaking study demonstrating that bacteria which are physically separated can transmit information through the air. It is well documented that bacteria can exchange messages by releasing substances into a surrounding liquid culture... view more (2002-05-27)

Sexual frustration: programmed cell death prevents plant inbreeding
Scientists have demonstrated the importance of programmed cell death in preventing inbreeding in plants, according to research published in Nature today. Researchers at the University of Birmingham School of Biosciences have found that self-incompatibility, an important mechanism in plants that... view more (2004-05-19)

One protein, two channels: Scientists explain mechanism in aquaporins
Using computer simulations and experimental results, researchers at the University of Illinois at Urbana-Champaign and the University of Arizona have identified a key component of the gating mechanism in aquaporins that controls both the passage of water and the conduction of ions.   view more (2006-09-22)

Chromosome glue repairs damaged DNA
When a strand of DNA breaks in the body's cells, it normally does not take long until it has been repaired. Now researchers at the Swedish medical university Karolinska Institutet have discovered a new mechanism that helps to explain how the cell performs these repairs. The results are presented in... view more (2007-07-16)

Novel mechanism for DNA replication discovered
Since the discovery of the structure of DNA by James Watson and Francis Crick in 1953, the paradigm for DNA replication has stated that the DNA itself codes for the appropriate pairings for replication.   view more (2005-09-30)

Light Receptors in Eye Play Key Role in Setting Biological Clock, Study Shows
Biologists at the University of Virginia have discovered a switching mechanism in the eye that plays a key role in regulating the sleep/wake cycles in mammals.   view more (2008-08-18)

Agent orange chemical, dioxin, attacks the mitochondria to cause cancer, says Penn research team
Researchers with the University of Pennsylvania School of Veterinary Medicine have demonstrated the process by which the cancer-causing chemical dioxin attacks the cellular machinery, disrupts normal cellular function and ultimately promotes tumor progression.   view more (2007-12-18)

Presence of certain antibodies signals healthier teeth and gums
Antibodies present in people with good oral health could become the first tool for dental professionals to assess a patient's probable response to periodontal disease treatments, say researchers at the University of Michigan.   view more (2008-04-24)

Pathogens use previously undescribed mechanism to sabotage host immune system
New research identifies a previously unknown enzymatic mechanism that subverts the early host immune response and promotes pathogenicity by manipulating a common signaling pathway in host cells.   view more (2007-12-10)

The molecular mechanism of a diabetes vaccine revealed
A team of researchers led by Prof. Irun Cohen of the Weizmann Institute of Science Immunology Department has revealed the molecular mechanism of a vaccine for Type 1 diabetes.   view more (2006-06-20)

Cincinnati Children's researchers publish findings on potential target for leukemia treatment
Cincinnati Children's Hospital Medical Center today announced the publication of pioneering research identifying the crucial role and novel mechanism of action of the protein RhoH GTPase in the development and activation of cells critical to the immune system.   view more (2006-10-10)

Laughing Gas in a Vicious Circle
Italian researchers discover another mechanism for the formation of atmospheric N2O Summer smog, the ozone hole, the greenhouse effect – the complex web of chemical reactions in the atmosphere, which leads to manifold environmental problems, is still not fully cleared up. In a tricky way, a... view more (2001-05-15)
