UAB scientists discover the origin of a mysterious physical force

...c field is pointing. However, when the water is in contact with surfaces that create small electric fields, such as chemical compounds like those found in many detergents, this is no longer the case: the water molecules have a remarkable capacity to organise themselves into complex structures that are strong...

SARS coronavirus was detected in the air in a patient's room during the 2003 outbreak in Toronto, according to a new study published in The Journal of Infectious Diseases. Another stud...

Protein offers way to stop microscopic parasites in their tracks

...ch to the exterior of the host cell. The resulting contact points give the belt something to push against as it moves backward, in turn pushing the parasite forward. But these adhesive spots have a significant disadvantage in comparison to a chain: if the belt is to continue rotating, the glue spots have to...

...en undercooked or poorly handled poultry, although contact with contaminated water, livestock, or household pets can also cause disease. In 2000, C. jejuni was the first food-borne pathogen to be completely sequenced, but we still know little about how Campylobacter species cause disease. In their search fo...

(For more info, contact Nick Wolff, 207-228-8069, or nwolff@usm.maine.edu) The Dynamic Atlas will serve as a pilot for a truly integrated ocean observing system, called the Gulf of Maine Biogeographic Information System. Over time the Census of Marine Life will work with t...

Viral protein influences key cell-signaling pathway

...ocytes. The virus is spread by sexual activity, by contact with infected blood and by infected women to children through breast milk. HTLV-1, like its cousin HIV, inserts its genetic information permanently into the DNA of a T lymphocyte and remains there for the life of the cell. HTLV-1 infection is also l...

Fibril Shape Is The Basis Of Prion Strains And Cross-species Prion Infection

To create avoidable, detectable, safer gear, the team tinkered with the chemical properties of the ropes. A group of scientists from the Central Institute of Fisheri...

Potential Drug Target For Treating Cocaine Abuse Found

.... The researchers found that their novel drug made contact with transporters slowly ?about 10 times slower than cocaine ?which, they speculate, may be why it does not have a stimulating effect. Between 2 million and 3.2 million people in the United States ?about 1 percent of the population - use cocaine, ac...
