A team of researchers from YOKOHAMA National University, Japan, have discovered a previously unknown species of marine fungus that can kill harmful, bloom-forming algae.

The new species, Algophthora mediterranea, is a form of microscopic chytrid fungus that can occupy a broad range of hosts, suggesting that chytrid fungi – a diverse group of aquatic fungi – may play a greater role in marine ecosystems than previously thought.

Critically, the fungus was identified as a destructive parasite in a species of algae, Ostreopsis cf. ovata, known to cause toxic blooms that have adverse health effects on humans. The findings are published online in Mycologia on December 15, 2025.

Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA. A research team from IOCB Prague has now described in detail how cells repair this damaged genetic information. Their study provides new insight into the link between alcohol consumption and the development of cancer. The findings were published in the Nature Portfolio journal Communications Biology.

Researchers from the University of Maine and Bigelow Laboratory for Ocean Sciences, have developed a faster, more accurate way to detect a toxic species of algae known as Pseudo-nitzschia australis (P. australis). It's a test that uses a quantitative version of the Polymerase Chain Reaction (qPCR) to pinpoint P. australis in environmental DNA (eDNA) samples using a unique genetic marker. By being faster and more accurate, this test can help the shellfish industry better track and respond to harmful algae blooms. 
 

An experimental pain-relieving drug delivery method for farm animals using biodegradable microneedle patches was conducted by researchers with the Arkansas Agricultural Experiment Station to alleviate some pain after procedures like castrations and tail docking and decrease labor for farmers. While the drugs administered through the experimental microneedle pain patches on pigs did show up in the animals’ system, the drug concentrations were not sufficient.

Despite the limited performance, the project remains a proof of concept that pig skin can absorb medication delivered through a dissolvable microneedle patch. The research team also found that the patches work better on the neck than the ear. No adverse responses were observed at application sites, highlighting the safety and tolerability of the patches. Additionally, a new approach is being developed using the microneedle patch technology as a way to incorporate tattoos for animal tagging.

A University of Houston computational chemist has received a $1.96 million federal grant to study how light transforms small molecules, work that could open new avenues for storing and using chemical energy, and for designing materials that change when exposed to light.
