A new study published in Current Biology identifies the biological triggers that promote quicker nerve regeneration. From their previous studies, the researchers knew that damaged nerves regrow more quickly when “stress granules” in the site of the nerve injury are broken apart. Now they know what causes those stress granules to disassemble through a process called protein phosphorylation.

“The important thing is that we identified the protein that drives that process and showed how that’s regulated,” Jeff Twiss, a UofSC biology professor and co-author on the paper, said.

“It actually opens something new,” Pabitra Sahoo, the paper’s lead author, said...

Engineers have made their initial design more practical, efficient, and scalable. Researchers at MIT and elsewhere have significantly boosted the output from a system that can extract drinkable water directly from the air even in dry regions, using heat from the sun or another source.

The system, which builds on a design initially developed three years ago at MIT by members of the same team, brings the process closer to something that could be...

Finding lost star siblings. Star clusters have been part of the Imaginarium of human civilization for millennia. The brightest star clusters to Earth, like the Pleiades, are readily visible to the naked eye. A team has now revealed the existence of massive stellar halos, termed coronae, surrounding local star clusters.

“Clusters form big families of stars that can stay together for large parts of their lifetime...
