Single-atom tractor beams power chemical catalysis

By trapping light into tiny gaps only a few atoms wide, a team from the NanoPhotonics Center at the Cavendish Laboratory at the University of Cambridge has magnified optical forces a thousand-fold, strong enough to force ...

Copying the small structures of Salvinia leaves

Several plants and animals have evolved surfaces with long-term (i.e., days to months) air-retainability to prevent wetting and submersion. One example is Salvinia, a plant floating on water. The secret "how do they maintain ...

Tiny plastic particles in the environment

Wherever scientists look, they can spot them: whether in remote mountain lakes, in Arctic sea ice, in the deep-ocean floor or in air samples, even in edible fish—thousands upon thousands of microscopic plastic particles ...

Scorpion venom to shuttle drugs into the brain

The Peptides and Proteins lab at the Institute for Research in Biomedicine (IRB Barcelona) has published a paper in Chemical Communications describing the use of a peptide derived from chlorotoxin, found in scorpion venom ...

Fish's rapid response to climate change

When a chemical alarm cue is released into one of two flumes, the normal response for a fish is to swim down the flume without the chemical. But when the water is more acidic, some fish do not behave normally: instead they ...
