Protists deserve the spotlight and so do scientists! This was such an honor but mostly, this project reminded me why I have the best job and friends/colleagues in the world! 🔬

Balendra Shah wore them as a rapper, as Kathmandu’s mayor and on his way to becoming prime minister. Now he has taken the look to the United Nations.

Some people are mosquito magnets while others go all summer without a single bite. Work from Rockefeller's @leslievosshall.bsky.social helps explain why: Mosquitoes prefer the scent of individuals with higher carboxylic acids. Learn more from the BBC: bbc.in/4wETph4

Why do mosquitoes bite some people more than others?
Long before they land, mosquitoes are reading our body signals from afar. Find out if you feature high on the bloodsuckers' hit list.
