Phys.org / Continued monitoring of sunken Soviet submarine shows ongoing radioactive leakage, but little impact

In 1989, the Soviet nuclear-powered attack submarine Komsomolets sank to the bottom of the Norwegian Sea, along with its nuclear reactor and two nuclear warheads onboard. Komsomolets was constructed with a titanium alloy ...

Phys.org / Europe's Late Neanderthals descended from a single population, DNA analysis suggests

A study incorporating new DNA data and archaeological evidence has shown that the last Neanderthals in Europe experienced a major population turnover, resulting in little diversity in their gene pool prior to their disappearance ...

Phys.org / Are humans naturally violent? New research challenges long-held assumptions

New research from the University of Lincoln, UK, is challenging a common assumption about the evolutionary origins of human violence, suggesting that everyday aggression does not inevitably lead to lethal conflict. The study, ...

Phys.org / What 'Project Hail Mary' gets right—and wrong—about astrophysics

"Project Hail Mary," the Ryan Gosling-led adaptation of the best-selling sci-fi novel from Andy Weir, is being praised for putting the science in science fiction. Although aliens, sun-draining microorganisms and galaxy-spanning ...

Phys.org / The 'private solution trap': Why richer countries may favor adaptation over public solutions, and who pays

A new study, led by the University of Nottingham and conducted by a team of 72 economists and psychologists across the world, has identified a potential "private solution trap" in problems requiring international cooperation ...

Phys.org / Moons orbiting wandering exoplanets could be habitable—with one catch

Provided they host thick, hydrogen-dominated atmospheres, moons orbiting free-floating exoplanets could retain much of the heat generated deep within their interiors by tidal forces. Led by David Dahlbüdding at the Max Planck ...
