Evolution of Old World fruit flies on three continents mirrors climate change
Fast-warming climate appears to be triggering genetic changes in a species of fruit fly that is native to Europe and was introduced into North and South America about 25 years ago.
Uranium 'pearls' before slime
Since the discovery a little more than a decade ago of bacteria that chemically modify and neutralize toxic metals without apparent harm to themselves, scientists have wondered how on earth these microbes do ...
Ancient Global Warming Drove Early Primates' Dispersal

Molecular ruler sets bacterial needle length
When a salmonella bacterium attacks a cell, it uses a nanoscopic needle to inject it with proteins to aid the infection. If the needle is too short, the cell won't be infected. Too long, and the needle breaks. ...
Cyborg beetle research allows free-flight study of insects
Hard-wiring beetles for radio-controlled flight turns out to be a fitting way to learn more about their biology. Cyborg insect research led by engineers at the University of California, Berkeley, and Singapore's ...
