Exploring animal life in the radioactive shadows of Chornobyl and Fukushima

Society for Experimental Biology
Reports and Proceedings

A team of researchers in France are building on fundamental experimental research undertaken in the Ukrainian Chornobyl exclusion zone with a new project in the Japanese Fukushima Prefecture to further our understanding of what it means for animals to live and reproduce in radioactive environments.

Omicron strain BA.2.86 emergence defies natural explanation

University of Tsukuba
Peer-Reviewed Publication

A researcher at University of Tsukuba investigated the origin of the Omicron BA.2.86 lineage of SARS-CoV-2, which emerged in the summer of 2023. He found that the strain had been sporadically detected in multiple, geographically distant locations worldwide. Moreover, the genetic mutations observed in this lineage diverged significantly from those typically seen in humans, making it difficult to account for through natural evolution.

Uncovering how ascidians measure time to adulthood

University of Tsukuba
Peer-Reviewed Publication

The ascidian Ciona (a genus of sea squirts) begins metamorphosis several tens of minutes after its larvae attach to rocks or other surfaces, transforming from larvae into adults. Researchers at University of Tsukuba have discovered that Ciona measures the time between attachment and the onset of metamorphosis by accumulating a substance called cyclic adenosine monophosphate (cAMP), which is responsible for signal transduction within cells.

Beetles under climate stress lay larger male eggs: Wolbachia infection drives adaptive reproduction strategy in response to rising temperature and CO₂

Kyushu University
Peer-Reviewed Publication

The azuki bean beetle is a common pest of stored beans and peas. Researchers at Kyushu University have found that when beetles infected with Wolbachia bacteria are exposed to elevated temperature and carbon dioxide they tend to produce larger eggs to enhance the survivability of their offspring. Interestingly, these larger eggs gave rise only to male larvae.

New study reveals surprising reproductive secrets of a cricket-hunting parasitoid fly

St. Olaf College
Peer-Reviewed Publication

The study describes how the embryos grow substantially in utero, likely receiving maternal nourishment during development, a reproductive mode known as adenotrophic viviparity.
