Medical Xpress / Host genetics and sex can steer flu toward greater virulence, mouse experiments reveal

During the early stages of a pandemic, viruses tend to evolve in ways that enhance their ability to reproduce and spread, rather than to evade the host's immune system. The genetics and sex of the host influence how a novel ...

Phys.org / Data from Earth's most remote atoll show soil fungi are key to island regeneration

Palmyra Atoll, a remote, uninhabited speck of land, coral and sea halfway between Hawaii and American Samoa, is one of the healthiest, intact atolls on the planet—so ecologically sensitive that visiting researchers freeze ...

Phys.org / How rocks trap CO₂ faster: Water-driven pathway could speed long-term carbon storage

Rocks can bind carbon dioxide—and much faster than previously thought. For a long time, it was assumed that the transformation of CO2 into carbonate rock depends on very slow, time-consuming processes. According to that view, ...
