Ant societies' arms race: Gene activity in defenders depends on invading slavemaking ants

Temnothorax americanus is a slavemaking ant found in northeastern America. In a new study, biologists examined the special relationship between the parasites and their host and made an exciting discovery: The ability of the host ants to defend themselves depends crucially on whether the raiding slavemakers come from an area with a successful or less successful parasite population.

After completing a series of human studies, the researchers concluded that the wireless sensors provided data as precise and accurate as that from traditional monitoring systems.

New findings shed light on origin of upright walking in human ancestors

The oldest distinguishing feature between humans and our ape cousins is our ability to walk on two legs - a trait known as bipedalism. Among mammals, only humans and our ancestors perform this atypical balancing act. New research provides evidence for greater reliance on terrestrial bipedalism by a human ancestor than previously suggested in the ancient fossil record.

'Megalodon' -- a giant predatory shark that has inspired numerous documentaries, books and blockbuster movies -- likely went extinct at least one million years earlier than previously thought, according to new research. This is a substantial adjustment as it means that O. megalodon likely went extinct long before a suite of strange seals, walruses, sea cows, porpoises, dolphins and whales all disappeared sometime about 1-2.5 million years ago.
