First lipid hormone discovered
An omega-7 fatty acid made by fat and liver cells acts as a hormone, even mimicking the health benefits of insulin.

Heat waves stunt grassland growth
An abnormally hot year can significantly suppress growth in grasslands, a stifling effect that lingers well into the next year even if temperatures return to normal. It can also hinder how well the grasslands absorb carbon dioxide from the atmosphere.

This bite won’t hurt a bit
A team dissects the physics of a mosquito bite, working to find a way to design gentler needles.
- Paleontology
Dino domination was in the cards, maybe
A new study finds that early dinosaurs coexisted with and were outnumbered by a competing species. Dinosaurs eventually reigned supreme anyway, but perhaps not because they were better.
