Dormant cancer cells rely on cellular self-cannibalization to survive
A single tumor-suppressing gene is a key to understanding, and perhaps killing, dormant ovarian cancer cells that persist after initial treatment only to reawaken years later, researchers at The University of Texas M. D. Anderson Cancer Center report in the December Journal of Clinical Investigation. view more (2009-01-05)
Researchers uncover new mechanism of tumor suppressor
Researchers from the University of Colorado-Denver and Health Sciences Center and Stanford University have discovered a molecular mechanism that explains how cells respond to DNA damage and other acute stresses, and if disrupted can cause cancer. view more (2006-05-22)
Tiptoe through the tulips
Scientists have discovered that plant leaves activate defence mechanisms against plant eating insects within twenty seconds of an insect walking across them. Dr Alan Bown will be presenting the results of his footsteps research at the Society for Experimental Biology conference on Tuesday 9 April. view more (2002-04-04)
System that regulates blood pressure is amiss in some healthy, young blacks
When stress increases blood pressure, a natural mechanism designed to bring it down by excreting more salt in the urine doesn't work well in about one-third of healthy, black adolescents, researchers report. view more (2009-05-11)
Researchers peg magnetism as key driver of high-temperature superconductivity
When it comes to superconductivity, magnetic excitations may top good vibrations. view more (2006-07-06)
UI chemists' DNA biosynthesis discovery could lead to better antibiotics
Combating several human pathogens, including some biological warfare agents, may one day become a bit easier thanks to research reported by a University of Iowa chemist and his colleagues in the April 16 issue of the journal Nature. view more (2009-04-17)
Study suggests possible clue to miscarriage (pp 96, 129)
Low concentrations in early pregnancy of a protein involved in the immune system could be a potential indicator for miscarriage, suggest authors of a research letter in this week's issue of THE LANCET. Around 10-15% of pregnancies result in miscarriage, with no treatment available to prevent fetal loss and no biological markers to identify women... view more... (2004-01-07)
Researchers identify target for therapeutic drugs to fight most common adult brain cancer
A research team at UT Southwestern Medical Center has discovered a cell-signaling mechanism instrumental in the most common brain cancer in adults. view more (2006-01-16)
Breakthrough for treatment of fatal heart condition
Researchers at the University of Leeds have found a mechanism to prevent a potentially fatal heart condition that can strike without warning. view more (2007-06-06)
New wrinkle in the mystery of high-Tc superconductors
In the twenty years since the discovery of high-temperature (Tc) superconductors, scientists have been trying to understand the mechanism by which electrons pair up and move coherently to carry electrical current with no resistance. view more (2006-03-17)
Received Truth Turned On End In Cancer Research
It has long been the accepted view of cancer researchers that there is a difference between the mechanism behind the development of leukemias, on the one hand, and solid tumors like breast cancer, prostate cancer, gastrointestinal cancer, etc, on the other. A research team at the Section for Clinical Genetics at Lund University in Sweden is now... view more... (2004-04-06)
Better immune defense against anthrax
Scientists discover a gene in anthrax-causing bacteria may help defend against this form of bio-warfare. view more (2009-09-09)
No-entry zones for AIDS virus
The AIDS virus inserts its genetic material into the genome of the infected cell. Scientists of the German Cancer Research Center have now shown for the first time that the virus almost entirely spares particular sites in the human genetic material in this process. This finding may be useful for developing new, specific AIDS drugs. view more (2009-11-13)
Newly-discovered mechanism can explain the Beckwith-Wiedemann syndrome
Researchers from Uppsala University have discovered a mechanism that silences several genes in a chromosome domain. The findings, published in today's on-line issue of Molecular Cell, have implications in understanding the human disorder Beckwith-Wiedemann syndrome. view more (2008-10-27)
Overbearing colored light may reveal a second mechanism by which birds interpret magnetic signals
Magnetic orientation is critical to the migratory success of many bird species. By studying the influence of light on the ability of migratory birds to orient to magnetic signals, researchers have found clues to suggest that birds' orientation abilities may be more complex than previously thought. view more (2005-08-23)
A Potential Anti-cancer Agent
Pateamine A (PatA), a natural product first isolated from marine sponges, has attracted considerable attention as a potential anti-cancer agent, and now a new activity has been found for it, which may reveal yet another anti-cancer mechanism. view more (2009-11-03)
UIC scientists discover how some bacteria survive antibiotics
Researchers at the University of Illinois at Chicago have discovered how some bacteria can survive antibiotic treatment by turning on resistance mechanisms when exposed to the drugs. The findings, published in the April 24 issue of the journal Molecular Cell, could lead to more effective antibiotics to treat a variety of infections. view more (2008-05-01)
Caesar researchers discover a mechanism in the pathogenesis of breast cancer
New approaches in breast cancer therapy view more (2005-05-17)
Common bacteria pirate natural mechanism to get inside cells
Bacteria and viruses utilize a natural mechanism to get inside cells and grow, researchers say. view more (2006-01-26)
How plants learned to respond to changing environments
A team of John Innes centre scientists lead by Professor Nick Harberd have discovered how plants evolved the ability to adapt to changes in climate and environment. view more (2007-07-13)
