Odd energy mechanism in bacteria analyzed
Scientists at Oregon State University have successfully cultured in a laboratory a microorganism with a gene for an alternate form of photochemistry - an advance that may ultimately help shed light on the ecology of the world's oceans.   view more (2005-11-04)

Researchers shed light on mechanism of action used by anti-cancer drug
Virginia Commonwealth University Massey Cancer Center researchers have uncovered a new mechanism of action of the anti-cancer drug sorafenib, which could stimulate the development of novel regimens in which it is combined with other molecularly targeted agents for patients with blood cancers and... view more (2007-06-12)

How to share a bat
New research shows how different species of plants evolve unique floral adaptations in order to transfer pollen on different regions of bats' bodies, thus allowing multiple plant species to share bats as pollinators.   view more (2007-08-23)

Aging brain reduces ovulation
Dutch researcher Annelieke Franke has discovered that the aging of the brain adversely affects the fertility of female rats. The scientist suspects that her research will provide insights into fertility problems of women over the age of 30. Franke studied relatively young subfertile rats. Although... view more (2003-10-10)

More evidence for 'stripes' in high-temperature superconductors
An international collaboration including two physicists from the U.S. Department of Energy's Brookhaven National Laboratory has published additional evidence to support the existence of "stripes" in high-temperature (Tc) superconductors.   view more (2006-04-27)

New Effects Of Herbicides On Plants
The aim of Navarre engineer Ana Zabalza Azn'¡rez's PhD thesis - entitled "The inhibition of the biosynthesis of amino acids in ramified chain and their use as a target-site for herbicides" - was to find out what effects herbicides produce on the metabolism of plants so as to enable a more... view more (2004-01-22)

Finding victims in post-disaster spaces
When earthquakes strike, people often get trapped in buildings. Search and rescue teams can pinpoint some victims using sniffer dogs and sensors. But a new European system that takes pictures during or after a building collapse promises to save many more lives.   view more (2004-09-17)

UVA researchers explain cell response to skin-damaging UV rays
It's well known that overexposure to ultraviolet rays from the sun can cause major skin problems, ranging from skin cancer to sunburns and premature wrinkles. A tan, for example, is nature's own UV protection and an unhealthy sign that your skin is damaged.   view more (2007-10-02)

How does Fu-Zheng-Jie-Du-Decoction act on PTEN expression in hepatocellular carcinoma?
Many hepatocellular carcinoma (HCC) patients in China may be treated with Traditional Chinese medicine (TCM). Some say it works, others doubt its effectiveness. These stated that a research group in China had found TCM can down-regulate the expression of PTEN in HCC, which may suppress tumor cell... view more (2008-01-17)

Therapeutic prospects beyond Vioxx
Researchers at the University of Pennsylvania School of Medicine have clarified the mechanism by which drugs like Celebrex and Vioxx cause heart problems, in multiple animal models.   view more (2006-04-14)

Even occasional use of spray cleaners may cause asthma in adults
Using household cleaning sprays and air fresheners as little as once a week can raise the risk of developing asthma in adults, say researchers in Europe.   view more (2007-10-12)

Oregon researchers discover a mechanism leading to cleft palate
By creating a genetic mutation in zebrafish, University of Oregon scientists say they've discovered a previously unknown mechanism for cleft palate, a common birth defect in humans that has challenged medical professionals for centuries.   view more (2008-02-12)

MicroRNA gene that regulates lifespan found by Yale scientists
Genes that control the timing of organ formation during development also control timing of aging and death, and provide evidence of a biological timing mechanism for aging, Yale researchers report in the journal Science.   view more (2005-12-23)

The Sun Flooded Europe
It will be easy to predict typhoon appearance if you know where it arises. One of the cyclone forming regions is the northern part of the Mediterranean along the French and Italian coast. Most of last summer cyclones came from there and flooded many European countries and Southern Russia, and even... view more (2002-10-25)

Searching for shut eye: Penn study identifies possible sleep gene
While scientists and physicians know what happens if you don't get six to eight hours of shut-eye a night, investigators have long been puzzled about what controls the actual need for sleep. Researchers at the University of Pennsylvania School of Medicine might have an answer, at least in fruit... view more (2008-07-30)

Hot Paper in the Biochemical Journal
DNA DAMAGE INSIGHT An exciting new paper from the Biochemical Journal regarding the phosphorylation state of LKB1 in response to ionising radiation can be viewed online as an Immediate Publication at www.BiochemJ.org (DOI: 10.1042/BJ20021284). Researchers at the University of Dundee, the University... view more (2002-09-20)

Researchers explain odd oxygen bonding under pressure
Oxygen, the third most abundant element in the cosmos and essential to life on Earth, changes its forms dramatically under pressure transforming to a solid with spectacular colors. Eventually it becomes metallic and a superconductor.   view more (2008-08-05)

Making memories that last a lifetime
Neurobiologists have discovered a mechanism by which the constantly changing brain retains memories—from that dog bite to that first kiss. They have found that the brain co-opts the same machinery by which cells stably alter their genes to specialize during embryonic development.   view more (2007-03-15)

Untangling a pathology of Alzheimer's
Researchers have uncovered what appears to be a natural protective mechanism against a central cause of neuronal death in Alzheimer's and similar neurodegenerative diseases.   view more (2006-09-07)

Fertility hope as study shows eggs survive in older ovaries
In research that could have broad implications for women's fertility treatments, scientists have found that despite their age, female mice have a renewable egg supply in their ovaries.   view more (2006-07-06)

UIC researchers show how cancer-preventing foods work
Researchers at the University of Illinois at Chicago are unraveling the biochemical mechanism by which functional foods combat cancer.   view more (2005-07-11)

Physics and biology team up to tackle protein folding debate
A team of researchers from EPFL, (Ecole Polytechnique Fédérale de Lausanne), the University of Lausanne, Northwestern University and Tel Aviv University bring biology and statistical physics together to answer the question of how molecular chaperones fold, unfold and pull proteins... view more (2006-04-04)

Researchers reveal HIV peptide's possible pathway into the cell
Two theoretical physicists at Rensselaer Polytechnic Institute have uncovered what they believe is the long-sought-after pathway that an HIV peptide takes to enter healthy cells. The theorists analyzed two years of biocomputation and simulation to uncover a surprisingly simple mechanism describing... view more (2008-01-18)

Reagent under study as cancer vaccine may also help protect tumors
A bacterial mimic under study as a cancer vaccine because it signals the immune system to attack may also help some tumors hide, researchers have found.   view more (2005-11-01)

Odd protein interaction guides development of olfactory system
Scientists have discovered a strange mechanism for the development of the fruit fly antennal lobe, an intricate structure that converts the chaotic stew of odors in the environment into discrete signals in the brain.    view more (2007-10-30)
