Study points to genes responsible for malaria parasite's survival in attempts to eradicate it
Malaria is a nasty and often fatal disease, which may lead to kidney failure, seizures, permanent neurological damage, coma, and death. There are four types of Plasmodium parasites that cause the disease, of which falciparum, the subject of the recent study, is the most deadly. view more (2006-06-20)
'Thirst for knowledge' may be opium craving
Neuroscientists have proposed a simple explanation for the pleasure of grasping a new concept: The brain is getting its fix. view more (2006-06-21)
A natural chemical found in strawberries boosts memory in healthy mice
Mothers have long exhorted their children to eat their fruit and vegetables. But once kids are beyond mom's watchful eye, the hated greens often go the way of Barbie dolls and power rangers. Now, there's another reason to reach for colorful fruits past adolescence. view more (2006-10-18)
Leading cause of US food-borne illness makes its own pathway through cells
Yale researchers now have some answers about how the bacterium that is the leading cause of food-borne illness in the United States enters cells of the gut and avoids detection and destruction. view more (2007-01-12)
Myelin to Blame for Many Neuropsychiatric Disorders
What makes the human brain unique? Of the many explanations that can be offered, one that doesn't come readily to mind is - myelin. view more (2006-11-22)
Similar stem cells in insect and human gut
Scientists at the Carnegie Institution's Department of Embryology have found that adult fruitflies have the same stem cells controlling cell regulation in their gut as humans do. view more (2005-12-08)
Cell wall of pneumonia bacteria can cause brain and heart damage
Investigators at St. Jude Children's Research Hospital have discovered in mouse models how cell walls from certain pneumonia-causing bacteria can cause fatal heart damage; researchers have also shown how antibiotic therapy can contribute to this damage by increasing the number of cell wall pieces shed by dying bacteria. The team also demonstrated... view more... (2006-10-25)
The evolution of food plants: Genetic control of grass flower architecture
Scientists are interested in understanding genetic control of grass inflorescence architecture because seeds of cereal grasses (e.g. rice, wheat, maize) provide most of the world's food. view more (2006-01-23)
Identification of carbon dioxide receptors in insects may help fight infectious disease
Mosquitoes don't mind morning breath. They use the carbon dioxide people exhale as a way to identify a potential food source. But when they bite, they can pass on a number of dangerous infectious diseases, such as malaria, yellow fever, and West Nile encephalitis. view more (2006-12-14)
Study sheds light on signaling mechanism in stem cells, cancer
UCSF scientists have illuminated a key step in a signaling pathway that helps orchestrate embryonic development. view more (2005-10-26)
Protein holds back growth of head and neck tumors
A protein associated with the growth of head and neck tumors may be a tumor suppressor that could prevent the spread of cancer when it is expressed above normal levels. view more (2006-02-01)
Sleep chemical central to effectiveness of deep brain stimulation
A brain chemical that makes us sleepy also appears to play a central role in the success of deep brain stimulation to ease symptoms in patients with Parkinson's disease and other brain disorders. The surprising finding is outlined in a paper published online Dec. 23 in Nature Medicine. view more (2007-12-26)
New key brain target of fat hormone
Researchers have identified a new area of the brain that responds to the fat hormone leptin in regulating body weight and energy expenditure. view more (2006-01-19)
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)
Synthetic molecule causes cancer cells to self-destruct
Scientists have found a way to trick cancer cells into committing suicide. The novel technique potentially offers an effective method of providing personalized anti-cancer therapy. view more (2006-08-28)
The hormone of darkness: melatonin could hurt memory formation at night
What do you do when a naturally occurring hormone in your body turns against you? What do you do when that same hormone - melatonin - is a popular supplement you take to help you sleep? A University of Houston professor and his team of researchers may have some answers. view more (2007-11-16)
Lactic acid not athlete's poison, but an energy source-if you know how to use it
In the lore of marathoners and extreme athletes, lactic acid is poison, a waste product that builds up in the muscles and leads to muscle fatigue, reduced performance and pain. view more (2006-04-20)
Omega-6 fats cause prostate tumors to grow twice as fast
Omega-6 fatty acids-such as those found in corn oil-caused human prostate tumors in cell culture to grow twice as quickly as tumors to which omega-6 fats had not been added, according to a study conducted at the San Francisco VA Medical Center. view more (2006-02-01)
Infection-fighting protein could be key to autoimmune disease, say U-M scientists
Scientists at the University of Michigan Medical School have discovered that a protein called cryopyrin responds to invading bacteria by triggering the activation of a powerful inflammatory molecule called IL-1beta, which signals the immune system to attack pathogens and induces fever to protect the body against infection. view more (2006-01-12)
Enzyme discovery sheds light on vitamin D
Surprising findings by Queen's researchers have shed new light on how the "sunshine vitamin" D - increasingly used to treat and prevent cancer and other diseases - is broken down by our bodies. view more (2007-07-25)
