A new study on the genomic signatures of adaptation in crop plants can help predict how crop varieties respond to stress from their environments. A new study led by a Kansas State University geneticist has shown that genomic signatures of adaptation in crop plants can help predict how crop varieties respond to stress from their environments.

New research at Rice University shows how tumors create chaos in the development of neighboring blood vessels, causing them to grow too quickly and not form properly. Rice University researchers have built a simulation to show how cancerous tumors manipulate blood-vessel growth for their own benefit.

Antibodies bind to a flu virus protein (grey) with their variable regions (blue) forming an immune complex. The antibodies' Fc region (red) will bind to immune cells. Flu vaccines can be something of a shot in the dark. Not only must they be given yearly, there's no guarantee the strains against which they protect will be the ones circulating once the season arrives.

Since Ebola was first described in 1976, there have been several outbreaks, but all have been self-limiting. In a new Journal of Internal Medicine review, Dr. Ali Mirazimi of the Karolinska Institutet considers why the latest outbreak occurred and discusses the factors that contributed to making it the largest, most sustained, and most widespread outbreak of Ebola. He also notes that several potential treatments are now undergoing clinical trials and have shown initial promising results.

Scientists have discovered new ways in which the malaria parasite survives in the blood stream of its victims, a discovery that could pave the way to new treatments for the disease.
