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 ...

Thermodynamic properties of hevein

Hevein is a small protein (4.7 kDa) consisting of forty-three amino acid residues. It is the main component of the bottom fraction of rubber tree (Hevea brasiliensis) latex that has a pronounced antimicrobial activity, thus ...

Chirality in real time

Distinguishing between left-handed and right-handed (chiral) molecules is crucial in chemistry and the life sciences, and is commonly achieved using a method called circular dichroism. However, during biochemical reactions, ...

Engineers repurpose wasp venom as an antibiotic drug

The venom of insects such as wasps and bees is full of compounds that can kill bacteria. Unfortunately, many of these compounds are also toxic for humans, making it impossible to use them as antibiotic drugs.
