How cytoplasm 'feels' to a cell's components
In a study that may guide drug design, researchers find organelles encounter varying levels of resistance, depending on their size and speed, as they move through a cell's cytoplasm.

How humans and their gut microbes may respond to plant hormones
A bowl of salad contains more than vitamins and minerals. Plant matter also includes remnants of the hormones plants produce to control how they grow, age, and manage water intake. Recently, scientists have reported that our gut microbes and cells may respond to these hormones and even produce similar molecules of their own. Researchers now explore how plant hormones may influence human health.

Postnatal identification of Zika virus peptides from saliva
For the first time, researchers are using proteomics to examine proteins and peptides in saliva in order to accurately detect exposure to Zika virus. With 70 countries and territories reporting evidence of mosquito-borne Zika virus transmission, there is an increased need for a rapid and effective test for the virus. This study offers a new, quicker and more cost-effective way to test for the virus.
