Study identifies potential targets for treating venous ulcers
ELIFE The study, which includes the first resource detailing the role of microRNAs in the wound-repair process, shows that aberrant levels of a trio of microRNAs may impair healing in venous ulcers. The findings suggest that drugs targeting these microRNAs could help facilitate healing in patients. Venous ulcers commonly occur in the legs, caused by...

How does monkeypox spread? An expert explains why it isn’t an STI and what counts as close contact
by Rebecca S.B. Fischer, The Conversation This microscopy image shows monkeypox particles, colored red, within an infected cell, colored blue. Credit: NIAID Monkeypox is caused by a virus that, despite periodic outbreaks, is not thought to spread easily from person to person and historically has not spurred long chains of transmission within communities. Now, many researchers are left...

A role for cell ‘antennae’ in managing dopamine signals in the brain
by Emily Caldwell, The Ohio State University Microscope image of a cultured mouse neuron from the striatum region of the brain labeled with a green fluorescent antibody that detects dopamine receptor 1. The receptor localizes along the cell surface and is enriched in a primary cilium projecting from the cell body. Nuclei are indicated in...
