Genetic cause of innate resistance to HIV/AIDS
Some people may be naturally resistant to infection with HIV, the virus that causes AIDS. The results of a study conducted by Dr. Nicole Bernard of the Research Institute of the McGill University Health Centre (MUHC) bring us closer to a genetic explanation. Her study findings were published on... view more (2008-07-17)

UAB Researchers Discover a New Mechanism Involved in Predisposition to Cancer
A team of researchers at the Universitat Autònoma de Barcelona (UAB) has discovered a new mechanism that accelerates the shortening of telomeres (structures that protect the ends of chromosomes) involved in genetic instability and a predisposition to cancer. The research has been published... view more (2002-02-26)

Cytomegalovirus exacerbates atherosclerosis through an autoimmune mechanism
A new study conducted by researchers from the University of Verona and the Institute G. Gaslini in Genova, Italy, confirms the pivotal role played by Cytomegalovirus infection in the pathogenesis of atherosclerosis.   view more (2007-05-30)

New compound effectively treats fungal infections
A new mechanism to attack hard-to-treat fungal infections has been revealed by scientists from the biotech company Anacor Pharmaceuticals Inc., California, and the European Molecular Biology Laboratory [EMBL] outstation in Grenoble, France.   view more (2007-06-25)

'Invisible' bacteria dupe the human immune system
Scientists at the University of York have characterised an important new step in the mechanism used by bacteria to evade our immune system.   view more (2008-02-20)

Study reveals mechanism for cancer-drug resistance
Using the worm Caenorhabditis elegans, researchers at UT Southwestern Medical Center have discovered a mechanism by which cancer cells become resistant to a specific class of drugs.   view more (2006-10-10)

More than two billion Euros per year to strengthen European research
The European Science Foundation (ESF) welcomes the suggestion of creating a new funding mechanism for supporting European research in the form of a European Research Council.   view more (2003-12-19)

Imiquimod, an immune response modifier, is dependent on the OGF-OGFr signaling pathway
Researchers at The Pennsylvania State University College of Medicine, Hershey, Pennsylvania have discovered that the efficacy of imiquimod, a clinically important immune response modifier with potent antiviral and antitumor activity, is dependent on the Opioid Growth Factor (OGF)-OGF receptor... view more (2008-07-28)

Apelin to rescue diabetics
Sugar is naturally present in the blood in the form of glucose and is stored in the liver or adipose tissue (fat) thanks to the action of insulin. Glucose is stored or directly used to ensure satisfactory function of the heart, brain and so on according to the body's demands.   view more (2008-11-05)

Researchers uncover protection mechanism of radiation-resistant bacterium
Recent discoveries by researchers at the Uniformed Services University of the Health Sciences (USU) could lead to new avenues of exploration for radioprotection in diverse settings. Michael J. Daly, Ph.D., an associate professor in USU's Department of Pathology, and his colleagues have uncovered... view more (2007-03-21)

Brandeis researchers propose model of neural circuit underlying working memory
Our ability to understand speech or decide which fruit in the store is freshest depends on the brain's dexterity in integrating information over time.   view more (2005-12-21)

Turning on cell-cell communication wipes out staph biofilms
University of Iowa researchers have succeeded in wiping out established biofilms of Staphylococcus aureus (staph) by hijacking one of the bacteria's own regulatory systems. Although the discovery is not ready for clinical application, the findings offer insight into a dispersal mechanism for staph... view more (2008-05-01)

Tropical disease experts call for a 'Global Fund to Fight Neglected Tropical Diseases'
An international team of tropical disease control experts has urged the global health and development community, and particularly the G8 leaders, to establish a new financing mechanism to combat the neglected tropical diseases (NTDs) of poverty.   view more (2008-03-26)

Researchers discover key mechanism by which lethal viruses Ebola and Marburg cause disease
Researchers in the Greene Infectious Disease Laboratory at Columbia University's Mailman School of Public Health, the Centers for Disease Control and Prevention, and the Caribbean Primate Research Center have discovered a key mechanism by which the Filoviruses, Ebola and Marburg, cause disease.   view more (2006-10-17)

Findings relate aspirin-induced ulcers, hearing loss
It's well known that high doses of aspirin can cause ulcers and temporary deafness, but the biochemical mechanism responsible for these phenomena has never been deciphered.   view more (2005-09-20)

Researchers find the mechanism by which cells resist chemotherapy
In his paper, to be published in The EMBO Jorunal, Dr SurrallĂ©s describes how proteins of the Fanconi/BRCA pathway recognise the presence of genetic mutations in order to repair them.   view more (2007-03-05)

New gene regulation mechanism discovered
Researchers at Cold Spring Harbor Laboratory have discovered a new kind of messenger RNA molecule that is converted from non-protein coding status to protein coding status in response to cellular stress such as viral infection.   view more (2005-10-21)

Why is the North Pole frozen?
Ice has been building up in the Arctic for 2.7 million years. Until now, no-one has been able to prove what mechanism brought about this accumulation of ice. However, a team of international scientists led by Antoni Rosell, a researcher for the Institute of Environmental Science and Technology at... view more (2005-02-23)

SLU Researchers Uncover Direct Evidence on How HIV Invades Healthy Cells
Using sophisticated detection methods, researchers at the Saint Louis University Institute for Molecular Virology (IMV) have demonstrated the molecular mechanism by which the HIV virus infects, or integrates, healthy cells. The discovery could lead to new drug treatments for HIV.   view more (2005-12-22)

New Genetic Mechanism For Evolution
A team of researchers from the Universitat Autònoma de Barcelona (UAB) has discovered that transposons, small DNA sequences that travel through the genomes, can silence the genes adjacent to them by inducing a molecule called antisense RNA. This is a new mechanism for evolution that has been... view more (2004-07-16)

Novel mechanism for long-term learning identified by Carnegie Mellon researchers
Practice makes perfect - or at least that's what we're told as we struggle through endless rounds of multiplication tables, goal kicks and piano scales - and it seems, based on the personal experience of many, to be true.   view more (2008-01-04)
