A novel CRISPR defense mechanism, unlike known nucleases, specifically destroys transfer ribonucleic acids (tRNA) that are ...

Earlier this spring, many of us had the privilege to see the solar eclipse while at the same time learning a lesson about defense mechanisms. For those of us who cared about preserving our vision, we ...

When confronted with an antibiotic, toxic substance, or other source of considerable stress, bacteria are able to activate a defense mechanism using cell-to-cell communication to 'warn' unaffected ...

Scientists have discovered a new CRISPR mechanism with precise activity, expanding the potential applications of the existing ...

One hormone found in platypus venom, glucagon-like peptide-1 (GLP-1), plays a role in increasing insulin and regulating blood sugar levels, which could potentially help with new diabetes treatments.

How much do you know about defense mechanisms? Defense mechanisms are psychological processes that someone unconsciously engages in to avoid discomfort, and there are several specific types. Take this ...

The defense mechanisms animals use to evade or fight off predators can be both bizarre and fascinating. Some use camouflage or mimicry, while others have protective armor. Sea cucumbers, however, use ...

A new international study led by the Gray Faculty of Medical & Health Sciences at Tel Aviv University finds: melanoma cancer ...

A (light green) bacterial cell detects a source of stress and is activated (dark green). It adorns itself with alarmones (depicted as red triangles) and can transmit them via cell-to-cell contact with ...
