Prolonged nutrient deprivation drives motif-specific DNA methylation changes in Flavobacterium columnare, a major fish pathogen. Using advanced Nanopore sequencing, researchers found that specific methylation patterns—especially demethylation of a 6mA-modified motif—serve as epigenetic signatures of starvation adaptation. Temperature also influences these changes. The findings reveal a novel survival mechanism in bacteria and provide a valuable methodological reference for bacterial epigenetics.

Researchers at Tohoku University look beyond the life-taking venomous stings of box jellyfish, and focus on life-creating processes in a new comprehensive study of their reproductive traits.

Researchers at iC3 have found a way to improve records of past high latitude ocean change using tiny plankton shells called foraminifera. By growing these foraminifera under controlled cold-water conditions, the team has extended a key temperature tool into the range most relevant for subpolar and polar oceans. The study’s results matter for anyone using marine sediments to reconstruct past climate, ocean circulation and carbon cycle change.

UF scientists created BlueME, a magnetoelectric antenna that lets underwater robots communicate over 700 meters. The robot‑to‑robot links enable real‑time decision‑making and data collection without plucking the robots out of the water. With a complete prototype, the researchers are seeking funding to continue the research.

New research reveals a potential link between the gut microbes of a fish and global ocean processes, offering new insight into how marine ecosystems help regulate ocean chemistry and the marine carbon cycle.

A new study published in Animal Behaviour found that bottlenose dolphins in Sarasota Bay, Florida, that engage in risky human-centric foraging behaviors, such as taking bait or catch from fishing gear, scavenging discarded bait or fish, or approaching humans for food tend to associate more with other dolphins that use similar tactics. The study also found that severe harmful algal blooms, commonly known as red tides, altered the relationship between these foraging behaviors and dolphin social structure. 

The research was led by Kyra Bankhead of Oregon State University, with co-authors Mauricio Cantor of Oregon State University, Katherine McHugh and Randall Wells of the Sarasota Dolphin Research Program, which is operated by Brookfield Zoo Chicago.
