An entropy-based gene selection method for cancer classification using microarray data

...lied again to pare down the list of selected genes until a "minimal" subset is obtained that gives a satisfactory accuracy of classification. The algorithm was applied to three different data sets and the results obtained were compared to work done by others using the same data sets. This study presents a...

Jumping gene helps explain immune system's abilities

"Here the growing actin filaments push the bacterium against the membrane, forming long membrane projections called ...

Sequencing of marine bacterium will help study of cell communication

Rats infected as newborns grew up vulnerable to memory problems during an immune challenge

... and those who were infected are completely normal until they get that second immune system challenge. The relatively uncommon one-two punch seems to cause the problem, although researchers don't know how long it lasts. Still, says Bilbo, "This may go far to explain some of the individual variability in di...

How the environment could be damaging men's reproductive health

Thus, the recent findings of good semen quality and low frequency of testicular cancer in Lithuania may reflect the intrauterine environment situation more than 20 years ago. However, cryptorchidism can be detected immediate...

Dead zone area in Gulf could be increasing, researchers say

"If the physical conditions we noticed continue, it could mean an unusually strong hypoxic zone this year, and that's not good news." DiMarco said the team studied an area betw...

Nanoscale Diagnostic Sets Sights on Alzheimer's

...ADDLs would leak into the cerebrospinal fluid, but until now we couldn't detect them. Thanks to the extraordinary sensitivity of the BCA it's been possible to validate the prediction, and maybe even set the stage for creating the first clinical lab test for Alzheimer's disease.
