New research led by William R. Thomas, PhD, with Professor Liliana M. D谩valos, PhD, in the Department of Ecology and Evolution at Stony Brook University, shows how the Eurasian common shrew (Sorex araneus) changes its brain and bodily size throughout the year. The study, published online in eLife, reveals how changes in gene expression enable these small mammals to shrink their brain in winter and regrow it in spring, defying the typical mammalian pattern where organ size does not change. Their findings offer genetic clues to neurological and metabolic health in mammals.

In July 1982, researchers in New Zealand recorded unidentifiable sounds as a part of an experiment to characterize the soundscape of the South Fiji Basin. The sound consisted of four short bursts resembling a quack, which inspired the name of the sound 鈥淏io-Duck,鈥� and researchers came to a consensus that the sounds had to be biological. Ross Chapman will present his work analyzing the mystery sounds as part of the virtual 187th ASA Meeting, presenting the waveform and spectrum of the recordings, as well as further evidence that the work was a conversation between multiple animals.

In the last quarter century, most countries around the world have failed to adequately protect the human rights of their citizens. In that time, nations鈥� efforts to protect human rights have been stagnant 鈥� with the number of countries receiving failing grades easily twice as high as those receiving passing grades.

A new study reveals how sunlight can drive the purification of lake water by breaking down harmful contaminants. By comparing two photochemical pathways鈥攖riplet sensitization and direct photolysis鈥攖he research highlights how these mechanisms function differently across various lake environments. The study points out that while certain pollutants are degraded through organic carbon interactions, others rely heavily on sunlight intensity, suggesting a combined strategy for more effective water purification.
