An Osaka Metropolitan University-led research team assessed how varying IVM durations affect developmental competence and embryo quality in oocytes with fast- or slow-predicted NMS classified via machine learning.

A research team led by Prof. Tao Jiang and Prof. Jing Li from State Key Laboratory of Pathogen and Biosecurity, Academy of Military Medical Science, in collaboration with Prof. Shi-Shun Zhao from College of Mathematics, Jilin University and Prof. Jianwei Wang from NHC Key Laboratory of Systems Biology of Pathogens and Christophe Merieux Laboratory, National Institute of Pathogen Biology, Chinese Academy of Medical Sciences and Peking Union Medical College, developed a viral risk prediction framework named GIVAL based on the pre-trained viral protein language model vBERT. This study proposes a general intelligent prediction method for assessing adaptation risks of unknown viruses.

Research published in Nature Communications found that the SAR11 bacteria, one of the ocean's most abundant life forms, are not a single, uniform population as often thought. Instead, they are organized into stable, ecologically distinct groups, essentially specialized "teams" adapted to specific environments, such as the coast versus the open ocean. This means that one of the ocean's most important engines is far more complex than previously known.

From fruit flies that bite to a tiny mouse opossum and a feathered dinosaur preserved with the remains of its last meal, more than 70 new species were described this year by researchers at the American Museum of Natural History.

University of Vermont scientists developed a first-of-its-kind study that tracks thousands of generations of digital organisms replaying evolution hundreds of times. Their results were surprising. In some cases, changing the environment helped populations find higher fitness peaks; in others, it hindered them. This gives a bird’s-eye view of how evolution played out across many different environments—something that would be impossible to test in the lab. The biggest takeaway is that starting point really matters. A population’s history shapes how high it can climb and how hard the path is to get there, which means one population may not represents an entire species.

A new study finds menopause symptoms to be very frequently reported by female endurance athletes, with many perceiving a negative effect on their training and performance. The findings are published December 17, 2025 in the open-access journal PLOS One by Heather Hamilton of Old Dominion University, U.S., and colleagues.
