Phys.org / Rare bumble bee's downfall began long before effects from humans, study says

A rare North American bumble bee may have been on a path toward extinction long before modern human impacts, suggesting that its long-term genetic vulnerability made it especially fragile and less able to cope with both past ...

Phys.org / Gunboat diplomacy: How classic naval coercion has evolved into hybrid warfare on the water

Over the summer, the United States deployed warships to the Caribbean—ostensibly to menace drug traffickers but also as a none-too-subtle warning to Venezuela. Earlier in the year, a U.S. Navy destroyer bobbed along waters ...
