Well-preserved footprints from the Lower Cretaceous Jinju Formation of South Korea, 110 million years ago, show that an ancestor of modern-day crocodiles, named Batrachopus grandis, walked on two feet.

Palaeontologists knew that some crocodiles from the "age of dinosaurs" were more adapted to life on land than their modern relatives but those were smaller creatures, about three feet long with footprints showing they walked on all fours. Batrachopus grandis was instead 12 feet in size and bipedal. It is more like a Gorn from the television show "Star Trek" than what we think of as a crocodile.

What doesn't kill you makes you stronger is a popular phrase, but how true it ever was is unclear. Bones are not stronger after they break and while some people relax about small drama after real trauma, many also become more sensitized to stress instead of more resilient.

Ten years ago science journalists talked about functional MRI (fMRI) scans all of the time. Because if a part of the brain lit up when someone did, said, or read something, it went into a paper. Few asked who was doing the interpreting, how legitimate the scale was, and if it had any scientific relevance. We got media claims that fMRI would predict behavior and the resulting media attention caused scholars to rush to produce even more fMRI papers.

Cover crops are touted for their soil and water quality related benefits. A new paper found that incorporating cover crops with tillage results in increased cover crop decomposition rates and increased mineralization of nutrients from cover crop biomass.

Other studies have reported mixed results for corn-soybean grain yields when planted after cover crops.

A new paper uses a combination of cosmic voids – large expanding bubbles of space containing very few galaxies – and the faint imprint of sound waves in the very early Universe, known as baryon acoustic oscillations, that can be seen in the distribution of galaxies, to show how large structures in the distribution of galaxies in the Universe can provide the most precise tests of dark energy and cosmic expansion yet.

Though "energy medicine" and "oxygenated herbs" promoted by CNN's Chris Cuomo are woo, one notion ridiculed by journalists has merit; using light to disinfect areas and kill coronavirus.

Though chemicals are most common, they are not always practical or portable. Ultraviolet radiation in the 200 to 300 nanometer range will destroy the virus, it just requires UV radiation sources that emit sufficiently high doses of UV light. Current devices are things like expensive mercury-containing gas discharge lamps, which require high power, have a relatively short lifetime, and are bulky.
