A study conducted in the Bay Area of California found that birds' songs changed in speed, pitch and volume as human activity subsided during the pandemic lockdown. Researchers, who published their findings in Science, were able to compare the birds' singing before the shutdown with their singing during it, finding that the songs were quieter, faster and in a different pitch.

A new sequencing method has allowed researchers to find human-like Y chromosomes in Neanderthal DNA and the process is described in Science. Researchers estimate the Homo sapiens version of the Y chromosome took over the Neanderthal chromosome between 370,000 and 100,000 years ago.
More than 1,200 fossilized dinosaur teeth found in a riverbed in Morocco are adding to evidence that the Spinosaurus was a massive river-dwelling creature. Since most of the teeth found at the site belonged to the creature, it appears that Spinosaurus lived most of its life in the water, according to findings published in Cretaceous Research.
The National Cancer Institute has awarded a $1.7 million grant to the University of Arkansas for Medical Sciences to study multiple myeloma. Research will focus on a pair of drugs that show promise in delaying or preventing relapses in patients who have gone into remission.
The Farm Journal Foundation is offering free curricula focused on the country's agriculture system, including e-learning resources. The resources include videos and first-hand accounts from farmers and ranchers nationwide.
