Âé¶¹ÒùÔºicists show 'molecules' made of light may be possible

It's not lightsaber time, not yet. But a team including theoretical physicists from the National Institute of Standards and Technology (NIST) has taken another step toward building objects out of photons, and the findings ...

Controlling the internal structure of mitochondria

(Âé¶¹ÒùÔº)—One might think of mitochondria as devices for transporting electrons to their lowest energy state. Little bags of finely-tuned respiratory chain subunits which combine electrons extracted from food with oxygen, ...

Team shows how rivers creep and flow to shape landscapes over time

Rivers drive the evolution of Earth's surface by eroding and depositing sediment. But for nearly a century, geologists have puzzled over why theoretical models, which use principles of physics to predict patterns of sediment ...

Time-lapse photos and synched weather data unlock Antarctic secrets

In preparation for his upcoming fieldwork, Brown University research analyst Jay Dickson took 10,000 pictures of the inside of his freezer. He wasn't investigating disappearing food or making sure the light went off when ...
