US probes genetically modified wheat discovery

The US Department of Agriculture is investigating the discovery of genetically engineered wheat in an Oregon field, as outcry mounted Friday among consumer groups and Japan suspended some US imports.

Surges in latent infections: Mathematical analysis of viral blips

Recurrent infection is a common feature of persistent viral diseases. It includes episodes of high viral production interspersed by periods of relative quiescence. These quiescent or silent stages are hard to study with experimental ...

Microbial changes regulate function of entire ecosystems

A major question in ecology has centered on the role of microbes in regulating ecosystem function. Now, in research published ahead of print in the journal Applied and Environmental Microbiology, Brajesh Singh of the University ...

NASA image: Agricultural fires in western Mexico

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite detected dozens of fires burning in western Mexico on May 30, 2013. The fires are outlined in red.

Mathematical models to better combat HIV

The first few hours to days following exposure to human immunodeficiency virus (HIV) can be of critical importance in determining if infection occurs in a patient. But the low numbers of viruses and infected cells at this ...

NASA satellites watch the demise of Hurricane Barbara

NOAA's GOES-14 satellite captured Hurricane Barbara's landfall in southwestern Mexico and movement across land, northward toward the Gulf of Mexico. This 43 second animation of NOAA's GOES-14 satellite observations from May ...
