A full beard can absorb nearly 40 percent of the shock from a punch to the face, according to one winning study.

Rather than relying on samples that need to be shipped in glass vials and on ice, researchers have developed a new method that allows mouse sperm to be sent easily at room temperature using standard mail delivery.

The AlphaFold program from AI firm DeepMind has amassed a huge database of protein structures from humans and model organisms.

Lateral flow tests for COVID-19 can be very accurate and specific when used as directed, but introducing acidic fluids can cause the tests’ detecting antibodies to clump, which may read as a positive result.

Lab-grown cells from the reef-building coral Acropora tenuis provide new opportunities to study bleaching, symbioses, and biomineralization.

Stable, long-term cell lines will enable scientists to study everything from coral bleaching to biomineralization, knowledge that may help protect corals from ongoing climate change.

The material turns bright pink when it comes in contact with an enzyme produced by the fungus Candida albicans.

The chemist refined nuclear magnetic resonance technology, giving rise to the development of MRI.

Differences in how researchers prepare and image samples can lead to discrepancies in their results.

Two studies this month point to pooches’ quick detection of SARS-CoV-2 on material that touched the skin of infected participants, although the pups’ accuracy does not match that of RT-PCR.

Researchers find that SARS-CoV-2 variants can evade primer-probe sets and recommend that diagnostic assays include multiple targets for reliability.
