Age at woman’s first period can offer clues about long-term health risks

The Endocrine Society
Reports and Proceedings

The age at which a woman has her first period can offer valuable clues about her long-term risk for conditions like obesity, diabetes, heart disease and reproductive health issues, according to a study being presented Sunday at ENDO 2025, the Endocrine Society’s annual meeting in San Francisco, Calif.

High blood sugar may have a negative impact on men’s sexual health

The Endocrine Society
Reports and Proceedings

Metabolic health factors, including small increases in blood sugar, are the main drivers of change in the reproductive systems and sexual functioning of aging men, according to a study being presented Saturday at ENDO 2025, the Endocrine Society’s annual meeting in San Francisco, Calif.

Cutting to the core of how 3D structure shapes gene activity

Sanford Burnham Prebys
Peer-Reviewed Publication

In biology textbooks and beyond, the human genome and DNA therein typically are taught in only one dimension. While it can be helpful for learners to begin with the linear presentation of how stretches of DNA form genes, this oversimplification undersells the significance of the genome’s 3D structure. Problems with this 3D structure are associated with many diseases including developmental disorders and cancer.

Scientists at Sanford Burnham Prebys and colleagues in Hong Kong published findings June 27, 2025, in Genome Biology demonstrating a new approach for better understanding the human genome’s 3D structure and its influence.

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.
