A study in Proceedings of the Royal Society B has found that sperm whales in the Mediterranean Sea appear to be splitting into two vocal dialect groups, offering a rare view of culture changing in a wild animal population. The study analyzed nearly two decades of underwater recordings from an endangered, isolated group of whales…

A study in Nature Communications found that river turbines could help remote northern communities cut diesel use, even where long winters and frozen channels make renewable energy planning difficult. The study, led by researchers affiliated with the University of Ottawa and partner institutions, identified hundreds of Arctic and sub-Arctic communities where flowing rivers may support…
A study in Nature Astronomy reports a roughly 14-kilometer-thick layer deep in the Martian crust that may be the leftover base of a vast ancient magma system. Using seismic waves recorded by NASA’s InSight lander, the research team found evidence that Mars once stored, sorted and modified molten rock through a deep crustal plumbing network.…
A study in Nature Astronomy has linked a high-energy neutrino detected by IceCube to a dust-hidden galaxy about 11 billion light-years away. The galaxy, formally known as JCMT0402−0424 and nicknamed Shadow Blaster, gives astronomers a striking new candidate for one of the Universe’s hardest-to-trace signals. The finding matters because high-energy neutrinos are cosmic messengers that…
