Humans can easily identify sweet-tasting foods—and with pleasure. However, many carnivorous animals lack this ability, and whether birds, descendants of meat-eating dinosaurs, can taste sweet was previously unclear. An ...

How a bath sponge becomes a bio-based industrial filter

Researchers at TU Bergakademie Freiberg developed an innovative material from a cultured marine sponge. When the fibers of the sponge react with a copper-containing ammonia solution, such as that found in the electronics ...

The chemistry lab inside cells

Investigators from the Institute of Scientific and Industrial Research at Osaka University, together with Hiroshima Institute of Technology, have announced the discovery of a new protein that allows an organism to conduct ...

New Cas9 variant makes genome editing even more precise

CRISPR-Cas9 has revolutionized the field of genetics by its ability to cut DNA at defined target sites. Researchers are using the Cas9 enzyme to specifically switch off genes, or insert new DNA fragments into the genome. ...

Fingerprints, revisited

For more than a century, forensic scientists have linked criminals to crime scenes through the distinctive loops and whorls on their fingertips. But now, researchers are moving beyond simple pattern comparisons to glean more ...
