Asthma gene clusters identified

...at clusters of known genes have been identified as being activated in acute forms of childhood asthma. Dr. Hershey said the findings open the door to the possibility of developing treatments based on the unique genetic profile of patients. For example, specific therapies for acute asthma could be targeted...

Artifical cornea lets woman blind 20 years see

More likely, the researchers say, the ability to run evolved long ago, when vampire bats had to prey on faster South American athletes such as the agouti, a rodent about the size of a hare, which might wake up and take a ...

Yale researchers identify molecule for detecting parasitic infection in humans

...as responsible and which molecule of T. gondii was being recognized by the TLRs. "In this study we found that the recognition of T. gondii by the innate immune system is mediated by a new member of the TLR family, TLR 11, that we discovered last year," said Sankar Ghosh, professor of immunobiology at Yale...

Molecular Motors Cooperate In Moving Cellular Cargo, Study Shows

...id. "It appears that motors are somehow regulated, being turned on or off in a fashion that prevents them from simultaneously dragging the peroxisome." In the future, Selvin wants to combine FIONA and an optical trap technique to monitor the speed and direction of a peroxisome, and the force acting upon i...
