Researchers find differences in swallowing mechanism of Rett syndrome patients
Researchers at Wake Forest University Baptist Medical Center have found that the reflux and swallowing problems that are common symptoms in patients with Rett syndrome and other neurological impairments, may be caused by a different mechanism than they are in healthy individuals.   view more (2008-08-05)

Protein that provides innate defense against HIV could lead to new treatments
By identifying a protein that restricts the release of HIV-1 virus from human cells, scientists believe they may be closer to identifying new approaches to treatment. The research is published in the advance online edition of Nature Medicine.   view more (2008-05-27)

Fruit fly avoidance mechanism could lead to new ways to control pain in humans
At first, fruit flies eat like horses. Hatching inside over-ripe fruit where they were laid, they feed wildly in the sugar-rich environment until nature sends them an offer they can't refuse.   view more (2008-05-12)

New mechanism identified for resistance to targeted lung cancer drugs
An international research team, led by investigators from the Massachusetts General Hospital (MGH) Cancer Center and Dana-Farber Cancer Institute (DFCI), has found a new way that some lung tumors become resistant to treatment with targeted therapy drugs like Iressa and Tarceva.   view more (2007-04-27)

Hide and seek: Researchers discover a new way for infectious bacteria to enter cells
French scientists have learned how Listeria monocytogenes, which causes a major food-borne illness, commandeers cellular transport machinery to invade cells and hide from the body's immune system.   view more (2005-08-22)

Flip of genetic switch causes cancers in mice to self-destruct, Stanford researchers find
Killing cancerous tumors isn't easy, as anyone who has suffered through chemotherapy can attest. But a new study in mice shows that switching off a single malfunctioning gene can halt the limitless division of tumor cells and turn them back to the path of their own planned obsolescence.   view more (2007-07-31)

Separation Day Arrives for Mars Express and Beagle 2
After a joint journey of 250 million miles (400 million km), the British-built Beagle 2 spacecraft and the European Space Agency's Mars Express orbiter should now have parted and gone their separate ways. At 8.31 GMT, software on Mars Express was scheduled to send the command for the Beagle 2... view more (2003-12-19)

UCLA physicists report advance toward nanotechy approach to protein engineering
UCLA physicists report a significant step toward a new approach to protein engineering in the June 8 online edition, and in the July print issue, of the Journal of the American Chemical Society.   view more (2006-06-12)

New finding bubbles to surface, challenging old view
Chemical engineers have discovered a fundamental flaw in the conventional view of how liquids form bubbles that grow and turn into vapors, which takes place in everything from industrial processes to fizzing champagne.   view more (2007-08-21)

A low prevalence of H pylori in HIV-positive patients
Helicobacter pylori has been extensively studied and proven to be the main cause of chronic gastritis and peptic ulcer in the HIV-negative population.   view more (2007-10-17)

Listeria monocytogenes: how can a relatively innocuous food-borne pathogen induce a potentially fatal disease?
Listeria monocytogenes (L. monocytogenes) provokes listeriosis, a potentially fatal food-borne disease, which mainly affects pregnant women and immuno-compromised individuals where it can lead to death rate as high as 30%. Understanding the mechanism behind the disease is crucial to dealing with... view more (2004-04-20)

Boston University psychologists find neurological mechanism for subliminal learning
Watch out - you may learn something and not even know it, says Takeo Watanabe, an associate professor of psychology at Boston University's Center for Brain and Memory. Watanabe and his team recently pinpointed the mechanism that makes subliminal learning work. Watanabe will present the team's... view more (2005-05-26)

Researchers offer clues to how leaf patterns are formed
Pick up a leaf and it is hard not to notice the pattern made by the veins. For years, biologists, mathematicians and even poets and philosophers have tried to decipher the rules and regulations behind those varied designs and now new research published in part at the University of Alberta offers a... view more (2006-06-16)

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 (2006-10-11)

Bacteria checkmate yeasts and moulds
Lactic acid bacteria are found in many foods, for example, yoghurt, cheese or sauerkraut. These bacteria are desirable, as they change the taste and consistency of a raw material in such a way that a completely new foodstuff is created. In the manufacture of cheese, propionic acid bacteria also... view more (2005-04-01)

Fish with temperature-dependent sex determination face global warming
In vertebrates with separate sexes, sex determination can be genotypic (GSD) or temperature-dependent (TSD). TSD is very common in reptiles, where the ambient temperature during sensitive periods of early development irreversibly determines whether an individual will be male or female.   view more (2008-07-30)

A large step forward in the fight against African sleeping sickness
Each year, over 300,000 people die of African sleeping sickness (trypanosomiasis). Researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) connected to the Free University of Brussels are making strides in the battle against this disease.   view more (2006-04-10)

Scientists solve structure of gene regulator that plays key role in cancer
Scientists at The Wistar Institute have collaborated on a major advance in understanding a gene regulator that contributes to some of the deadliest cancers in humans. The culmination of 10 years' work, their research paves the way for the development of new cancer therapies.   view more (2008-02-14)

HSPH researchers discover natural inflammation-fighting mechanism in body-fat cells
Scientists have discovered a previously unknown molecular signaling pathway in body fat cells that normally acts to suppress harmful inflammation. Cellular stress caused by obesity, however, can override this protective function and convert the pathway into a trigger of chronic inflammation that... view more (2008-06-04)

A reduced arousal threshold in Drosophila mutants prevents them from staying asleep
Most short-sleeping mutant phenotypes in Drosophila (a genus of small flies) are characterized by an inability to stay asleep, most likely because of a reduced arousal threshold, according to a study published in the April 1 issue of the journal SLEEP.   view more (2008-04-01)

Fluoxetine: antidepressant and a possible new drug for the treatment of obesity
The Department of Nutrition and Bromatology of the Faculty of Pharmacy of Gasteiz, University of the Basque Country, is studying the action mechanism of fluoxetine in genetically fattened rats (Zucker fa/fa). Due to fluoxetine, those rats eat 50 % less. Therefore, the bodies put on less weight and... view more (2002-07-30)

A mutation that causes resistence to chemotherapy treatment of lung cancer has been discovered
Lung cancer, mainly caused by tobacco and inhaling radon gas, is the most lethal cancer in the western world. In Spain alone this disease causes around 15,000 deaths each year.   view more (1999-09-27)

Building brains: Mammalian-like neurogenesis in fruit flies
A new way of generating brain cells has been uncovered in Drosophila. The findings, published this week in the online open access journal Neural Development, reveal that this novel mode of neurogenesis is very similar to that seen in mammalian brains, suggesting that key aspects of neural... view more (2008-02-19)
