NewsBacteria involved in gum disease linked to increased risk of head and neck cancer
More than a dozen bacterial species among the hundreds that live in people’s mouths have been linked to a collective 50% increased chance of developing head and neck squamous cell carcinoma (HNSCC), a new study shows. Some of these microbes had previously been shown to contribute to ...

NewsBacterial ‘flipping’ allows genes to assume different forms
A new study has shown that inversions, which cause a physical flip of a segment of DNA and change an organism’s genetic identity, can occur within a single gene, challenging a central dogma of biology — that one gene can code for only one protein.

NewsMicrobes: atmospheric methane increase during pandemic due primarily to wetland flooding
A new analysis of satellite data finds that the record surge in atmospheric methane emissions from 2020 to 2022 was driven by increased inundation and water storage in wetlands, combined with a slight decrease in atmospheric hydroxide (OH).

NewsCan a drug-free nasal spray protect against deadly respiratory infections?
A novel nasal spray for preventing respiratory infections works by forming a protective coating on the nasal cavity, which captures airborne respiratory droplets and acts as a physical barrier against viruses and bacteria, while effectively neutralizing them.

NewsFeeding coral reefs can aid their recovery from bleaching events
Coral reefs will continue to experience severe heat stress as rising temperatures cause the oceans to become unbearably hot – but a new study shows that altering their feeding habits could allow local populations to avoid total extinction.

NewsDeeper corals may help shallow reefs recover in the Florida keys
Using the blushing coral star (Stephanocoenia intersepta), found throughout the Western Atlantic, researchers have investigated how coral populations at different depths and locations may be related or ‘connected’ to each other.
