A protein isolated from beneficial bacteria found in yogurt and dairy products could offer a new, oral therapeutic option for inflammatory bowel disorders (IBD), suggests a study led by Vanderbilt University Medical Center researcher Fang Yan, M.D., Ph.D
The Dance of the Cells: A Minuet or a Mosh? PDF Print E-mail
Wednesday, 25 May 2011 01:09
The physical forces that guide how cells migrate -- how they manage to get from place to place in a coordinated fashion inside the living body -- are poorly understood. Scientists at the Harvard School of Public Health (HSPH) and the Institute for Bioengineering of Catalonia (IBEC) have, for the first time, devised a way to measure these forces during collective cellular migration.

Cancer treatments often have the side effect of impairing the patient's immune system. This can result in life-threatening secondary infections from bacteria and fungi, especially since bacteria, like Staphylococcus aureus, are becoming multi-drug resistant (MRSA).
Genetic 'Wiring' of Seeds Revealed PDF Print E-mail
Friday, 20 May 2011 00:29

The genetic 'wiring' that helps a seed to decide on the perfect time to germinate has been revealed by scientists for the first time. Plant biologists at The University of Nottingham have also discovered that the same mechanism that controls germination is responsible for another important decision in the life cycle of plants -- when to start flowering.

New Technique Sheds Light on the Mysterious Process of Cell Division PDF Print E-mail
Friday, 20 May 2011 00:25
Using a new technique in which models of primitive cells are constructed from the bottom up, scientists have demonstrated that the structure of a cell's membrane and cytoplasm may be as important to cell division as the specialized machinery -- such as enzymes, DNA or RNA -- which are found within living cells.
Secrets of Plague Unlocked With Stunning New Imaging Techniques PDF Print E-mail
Wednesday, 18 May 2011 01:54
Researchers at Sandia National Laboratories have developed a super-resolution microscopy technique that is answering long-held questions about exactly how and why a cell's defenses fail against some invaders, such as plague, while successfully fending off others like E.coli.

Regret has long been viewed as an exclusively human thought, one which helps prevent us from repeating bad choices but becomes debilitating when it triggers obsessive thoughts about past actions.
Healing Power of Hydrogen Peroxide: How Injured Cells Regenerate During Wound Healing PDF Print E-mail
Friday, 27 May 2011 00:34
New information has come to light explaining how injured skin cells and touch-sensing nerve fibers coordinate their regeneration during wound healing. UCLA researchers Sandra Rieger and Alvaro Sagasti found that a chemical signal released by wounded skin cells promotes the regeneration of sensory fibers, thus helping to ensure that touch sensation is restored to healing skin.

Vitamin D, which is primarily absorbed from the sun, plays a role in protection against childhood asthma. Now, a new study led by Valencian researchers has shown that children who live in colder, wetter cities are at greater risk of suffering from this respiratory problem, since there are fewer hours of sunlight in such places.
Goat Milk Can Be Considered as Functional Food, Spanish Researchers Find PDF Print E-mail
