Macrophage white blood cell eliminating pathogens

Bumble bees may look clumsy and goofy hovering above a flower, but don’t be deceived: They’re among the hot rods of the insect world and able to fly 22 kilometers per hour. Even while hovering, their powerful wing muscles generate a lot of heat. Like any high-performance vehicle, the bees have ways to keep their motors cool—and a new study shows just how effective one of these methods can be. As a bumble bee hovers in place, the breeze it generates can lower the insect’s body temperature by 5°C, researchers report. Learn more: scim.ag/4tVySEJ

What do I miss in space other than my family? Weather! I miss wind and rain and the feeling of water because here in space, water floats! That's why we're here; we're doing experiments because we can take gravity out of the equation like I've done with the water here.

New paper today led by Han Hu on the 3D skull of Jeholornis! In addition to the bones, we managed to get some nice insights regarding the sclerotic rings and the endocast: Jeholornis was probably diurnal and had relatively good sense of smell academic.oup.com/zoolinnean/adv…
