Exploring the structures of xenon-containing crystallites      (via sciencedaily.com)     Original source 

Noble gases have a reputation for being unreactive, inert elements, but more than 60 years ago Neil Bartlett demonstrated the first way to bond xenon. He created XePtF6, an orange-yellow solid. Because it's difficult to grow sufficiently large crystals that contain noble gases, some of their structures -- and therefore functions -- remain elusive. Now, researchers have successfully examined tiny crystallites of noble gas compounds. They report structures of multiple xenon compounds.

Scientists achieve more than 98% efficiency removing nanoplastics from water      (via sciencedaily.com)     Original source 

Linked to cardiovascular and respiratory diseases in people, nanoplastics continue to build up, largely unnoticed, in the world's bodies of water. The challenge remains to develop a cost-effective solution to get rid of nanoplastics while leaving clean water behind. That's where Mizzou comes in. Recently, researchers created a new liquid-based solution that eliminates more than 98% of these microscopic plastic particles from water.

Rewriting the evolutionary history of critical components of the nervous system      (via sciencedaily.com)     Original source 

A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the Shaker family of ion channels were present in microscopic single cell organisms well before the common ancestor of all animals and thus before the origin of the nervous system.

Do smells prime our gut to fight off infection?      (via sciencedaily.com)     Original source 

In nematodes and humans, mitochondrial stress in the nervous system initiates a whole-body response that is most pronounced in the gut. A recent study showed that in nematodes, the odor of a pathogen triggers the nervous system to broadcast this response to the rest of the organism, prepping mitochondria in intestinal cells to fight a bacterial infection. Humans, too, may be able to sense pathogenic odors that prepare the gut for an infection.
