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)

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)

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... 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... view more (2004-04-06)

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)

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... 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)

Mechanism for the captation of nutrients in plants- unknown to date
Up to now it was thought that nutrients penetrated the interior of plant cells by means of substance-specific transporters. Nevertheless, researchers at the Agrobiotechnology Institute at the Public University of Navarra have shown that the nutrients (saccharose, amino-acids, etc.) penetrate the... view more (2005-05-06)

The difference between fish and humans: scientists answer century-old developmental question
Embryologists at UCL (University College London) have helped solve an evolutionary riddle that has been puzzling scientists for over a century.   view more (2007-10-11)

Quantum biology — Powerful computer models reveal key biological mechanism
Using powerful computers to model the intricate dance of atoms and molecules, researchers at Rensselaer Polytechnic Institute have revealed the mechanism behind an important biological reaction.   view more (2007-01-17)

A cancer gene causing tumours by a 'double-whammy' mechanism also reveals the key to a cure
Scientists at the Babraham Institute have discovered that a tiny change in a protein involved in cell survival is responsible for abnormal cell activity in the early stages of cancer. The protein, known as Bcl-xL, normally protects cells from dying; and when the DNA in cells becomes damaged,... view more (2004-01-21)

Accumulated bits of a cell's own DNA can trigger autoimmune disease
A security system wired within every cell to detect the presence of rogue viral DNA can sometimes go awry, triggering an autoimmune response to single-stranded bits of the cell's own DNA, according to a report in the August 22nd issue of the journal Cell, a Cell Press publication.   view more (2008-08-22)

T-beta-RIII joins the fight against breast cancer
Although the soluble factor TGF-beta has been shown to suppress the growth of tumor cells in the early stages of breast cancer, high levels of TGF-beta during the later stages of the disease are associated with a poor outcome.   view more (2006-12-08)

Gene against bacterial attack unravelled
Dutch researcher Joost Wiersinga from AMC Medical Centre in Amsterdam has unravelled a genetic defence mechanism against the lethal bacteria Burkholderia pseudomallei. The research is the next step towards a vaccine against this bacterium suitable for bioweapons.   view more (2008-10-29)

Natural mechanism for immune suppression paves way for cancer trials
A natural mechanism pirated by tumors and HIV to evade the immune response is opening the door to better treatment for these conditions, researchers say.   view more (2007-03-29)

Selfing DNA prevents genomes from mixing
Genomes of multicellular organisms are one of the greatest mysteries of biology. The more is discovered about them, the more questions are to be answered. One of such questions is connected with the size of a genome. As is known since the middle of the 20th century, the level of organization of an... view more (2002-10-11)

Mechanism in cells that generate malignant brain tumors may offer target for gene therapy
Researchers at Cedars-Sinai Medical Center's Maxine Dunitz Neurosurgical Institute who first isolated cancer stem cells in adult brain tumors in 2004 have now identified a molecular mechanism that is involved in the development of these cells from which malignant brain tumors may originate.   view more (2008-10-27)

UCR-led study identifies crucial mechanism involved in immune response against viruses
A research team led by UC Riverside scientists has shown that the common fruit fly can serve as an excellent model for studying the immunity animals are born with for fighting viral infections.   view more (2006-03-24)

Retinol for combating leukemia cells
Vitamin A, also known as retinol, is present in milk, liver, egg yolk, butter and other foodstuffs and as carotene in vegetables that have a yellow-orange colour, such as carrots and pumpkins.   view more (2006-01-09)
