Barrier in mosquito midgut protects invading pathogens
Scientists studying the Anopheles gambiae mosquito - the main vector of malaria - have found that when the mosquito takes a blood meal, that act triggers two enzymes to form a network of crisscrossing proteins around the ingested blood. view more (2010-03-12)
Researchers examine plant's ability to identify, block invading bacteria
Understanding how plants defend themselves from bacterial infections may help researchers understand how people and other animals could be better protected from such pathogens. view more (2010-03-04)
UMass Lowell researchers' findings suggest new ways to diagnose and treat Alzheimer's
A team of researchers at UMass Lowell has found a new mechanism by which a key protein associated with Alzheimer's disease can spread within the human brain. view more (2010-03-02)
Cells of Aggressive Leukemia Hijack Normal Protein to Grow, According to Penn Study
Researchers have found that one particularly aggressive type of blood cancer, mixed lineage leukemia (MLL), has an unusual way to keep the molecular motors running. The cancer cells rely on the normal version of an associated protein to stay alive. view more (2010-03-01)
New technique allows study of protein folding, dynamics in living cells
A new technique to study protein dynamics in living cells has been created by a team of University of Illinois scientists, and evidence yielded from the new method indicates that an in vivo environment strongly modulates a protein's stability and folding rate. view more (2010-03-01)
New Assay Helps Track Termites, Other Insects
An Agricultural Research Service (ARS)-developed method to safely and reliably mark termites and other insects over vast acreage so their movements can be tracked is just as effective as the previous method-and more affordable. view more (2010-02-18)
Dartmouth researchers describe how the cholera bacteria becomes infectious
In a new study, Dartmouth researchers describe the structure of a protein called ToxT that controls the virulent nature of Vibrio cholerae, the bacteria that causes cholera. view more (2010-02-16)
Grasping bacterial 'friending' paves the way to disrupt biofilm creation
Finding a biological mechanism much like an online social network, scientists have identified the bacterial protein VpsT as the master regulator in Vibrio, the cause of cholera and other enteric diseases. This discovery, now published in the journal Science, provides a major tool to combat enteric disease. view more (2010-02-12)
PCs around the world unite to map the Milky Way
At this very moment, tens of thousands of home computers around the world are quietly working together to solve the largest and most basic mysteries of our galaxy. view more (2010-02-11)
Barley protein concentrate could replace fishmeal in aquaculture feeds
Agricultural Research Service (ARS) scientists and Montana Microbial Products (MMP) of Butte, Mont., have developed a barley protein concentrate that could be fed to trout and other commercially produced fish. view more (2010-02-08)
Breakthrough by Danish Scientists in Preventing Maternal Malaria
Researchers at the University of Copenhagen have become the first in the world to synthesize the entire protein that is responsible for life-threatening malaria in pregnant women and their unborn children. view more (2010-02-05)
Scientists find ideal target for malaria therapy
Scientists at Washington University School of Medicine in St. Louis have identified a protein made by the malaria parasite that is essential to its ability to take over human red blood cells. view more (2010-02-04)
Prolactin blocks oncogene associated with poor prognosis in breast cancer
Researchers from the Kimmel Cancer Center at Jefferson have found a mechanism by which a hormone responsible for milk production blocks an oncogene that makes breast cancer more aggressive. view more (2010-02-04)
Plant derivative could help refine cancer treatment
Medical College of Georgia researchers are seeking to refine cancer treatment with an anti-inflammatory plant derivative long used in Chinese medicine. view more (2010-02-04)
MSU researcher identifies cell mechanism leading to diabetic blindness
Scientists have long known that high blood sugar levels from diabetes damage blood vessels in the eye, but they didn't know why or how. Now a Michigan State University scientist has discovered the process that causes retinal cells to die, which could lead to new treatments that halt the damage. view more (2010-02-02)
Secrets of immunologic memory
Investigators at Sanford-Burnham Medical Research Institute (Sanford-Burnham) have discovered a new way the cell surface protein, CD44, helps specific T helper (Th1) cells develop immunologic memory. view more (2010-01-29)
A gimmick-free weight-loss pill in the works
Leptin regulates appetite in mammals and its levels decrease when fasting and rise during meals. It has been proven to be an appetite suppressant when administered intravenously to pathologically obese people. view more (2010-01-27)
New potential to treat chronic obstructive pulmonary disease
Chronic obstructive pulmonary disease (COPD) is defined by emphysema and/or chronic bronchitis. It destroys the normal architecture of the lung and inhibits the mechanical aspects of breathing, which prevents necessary gas exchange. view more (2010-01-27)
Protein supplements are misused by athletes
Protein supplements don't improve performance or recovery time and, according to a recent study, such supplements are inefficient for most athletes. view more (2010-01-20)
Compounds that help protect nerve cells discovered by Duke team
Scientists at Duke University Medical Center have found some compounds that improve a cell's ability to properly "fold" proteins and could lead to promising drugs for degenerative nerve diseases, including Huntington's disease, Alzheimer's disease and Parkinson's disease. view more (2010-01-20)
