A fossil site in North Dakota records a stunningly detailed picture of the devastation minutes after an asteroid slammed into Earth about 66 million years ago, a paper out this week argues. Geologists have theorized that the impact played a role in the mass extinction at the end of the Cretaceous period, when all the dinosaurs (except birds) vanished. At the site, 3000 kilometers from the impact in Mexico, the researchers say they have discovered the chaotic debris left when tsunamilike waves…

Emerging Concepts in Carbon Nitride Organic Photocatalysis.
TLDR
This Review summarizes recently emerging concepts in heterogeneous carbon nitride photocatalysis, with an emphasis on the synthesis of organic compounds: 1) Illumination-Driven Electron Accumulation in Semiconductors and Exploitation (IDEASE); 2) singlet-triplet intersystem crossing in carbon nit Ride excited states and related energy transfer; 3) architectures of flow photoreactors; and 4) dual metal/carbon nitride photatalysis.
Helium-Induced Changes in Circulating Caveolin in Mice Suggest a Novel Mechanism of Cardiac Protection
TLDR
A critical role is suggested for circulating factors of cholesterol and sphingolipid-enriched invaginations of the plasma-membrane-containing caveolin proteins in He-induced organ protection in cardioprotection in vivo.
