While I'm not looking forward to my next break, hoping this compound will be aroun... Read More

UCLA researchers use new microscope to 'see' atoms for first time

The researchers used cryo-electron microscopy to image a virus structure at a resolution high enough to effectively "see" atoms, the first published instance of a virus image at such a resolution. Read More

Mosquitoes inherit DEET resistance

The indifference of some mosquitoes to a common insect repellent is due to an easily inherited genetic trait that can be rapidly evolved by later generations, a new study suggests.

By selective breeding, James Logan and colleagues at Rothamsted Research in Harpenden, UK, created strains of Ae... Read More

Fighting fungal infections with bacteria

A bacterial pathogen can communicate with yeast to block the development of drug-resistant yeast infections, say Irish scientists writing in the May issue of Microbiology. The research could be a step towards new strategies to prevent hospital-acquired infections associated with medical implants... Read More

Disease caused by insect bites can be transmitted to children at birth

A North Carolina State University researcher has discovered that bacteria transmitted by fleas -- and potentially ticks -- can be passed to human babies by the mother, causing chronic infections and raising the possibility of bacterially induced birth defects. Read More
