Nitrogen-rich diet reduces mosquitoes' ability to transmit Zika

Feed mosquitoes more nitrogen when they're young, and the adults are less likely to transmit the Zika virus, University of Florida scientists say. Now, researchers want to know why, and they're determined to discover how the findings can help further their research into the dangerous virus.

Researchers discover early biomarker for degenerative neurologic disease

Researchers have discovered a novel radioligand that can effectively differentiate progressive supranuclear palsy (PSP) from similar brain disorders, allowing for earlier and more reliable diagnosis of the disease.

Non-classical monocytes directly involved in regulation of immune response

Non-classical monocytes were long thought to play a purely surveillance role in the immune system. With the aid of a novel marker, Ludwig-Maximilians-Universitaet in Munich researchers have now shown that they are directly involved in the regulation of immune response
