A trio of statisticians at the University of Minnesota has found an association between union membership and lower mortality rates. In their study published in the journal Social Science & Medicine, Tom VanHeuvelen, Xiaowen Han and Jane VanHeuvelen analyzed data mortality rates tabulated in the Panel Study of Income Dynamics and calculated the impacts on longevity for people who belong to unions.

A team of life scientists at East China Normal University has found that at least one type of cold-blooded animal uses behaviorally-induced fever to battle infections. In their paper published in Proceedings of the National Academy of Sciences, the group describes how they put Nile tilapia, a type of fish, in tanks with a heat gradient, infected them with a bacterium and then watched how they behaved—and what they learned by doing so.

A team of chemists and biomedicine specialists at Nanjing University, in China, developed an "artificial tongue" based on biological nanopore technology that can be used to determine the chemical makeup of alcoholic drinks. In their paper published in Matter, the group describes how they developed their liquid analysis device and how well it worked when tested on various beverages.

A team of marine biologists, zoologists, and cetologists from Université Paris-Saclay, Université d'Antananarivo and Ambodiforaha Sainte Marie has learned more about the ways baby humpback whales and their mothers communicate.

A team of biology and optics researchers affiliated with a host of institutions in Spain has found that the unique undercoating of the barn owl helps to make it less visible to prey when flying under the moon and starlit skies.

A multi-institutional team from China and the U.S. has identified a molecule that may play a role in slowing the aging process in some animals consuming a restricted diet. The team has published two papers on their work in the journal Nature.
