Research team identifies new Alzheimer's gene
...ologies permit us to survey a sufficient number of letters
throughout the human genome to provide a clearer picture of how life works and ultimately allow better clinical management of patients,” said Dr. Dietrich Stephan, Director of TGen’s Neurogenomics Division and the paper’s senior author, “These new, r...
Anthrax paralyzes immune cells with lethal toxin, UF research shows
...nfection. Anthrax killed five people in 2001 when letters
containing the bacteria's spores were sent through the mail. The UF findings, published last week in the EMBO Journal, may lead to quicker diagnoses for anthrax victims. The disease causes flu-like symptoms that can take weeks to develop, accordin...
Danish researches solve virus puzzle

Individuals and populations differ in gene activity levels, not just genes
...years about genetic variation, in which individual letters
in the genetic code change between individuals and between different populations. However, this study is one of the first to look at the variation in gene activity between individuals and populations. The researchers found many differences in gen...
