Obese mice that exercised while pregnant gave birth to pups that grew up free of the metabolic issues present in the adult young of sedentary obese mothers—possibly by staving off epigenetic changes to a key metabolic gene.

Soranus of Ephesus’s manual shaped the way midwifery was practiced for more than a millennium.

Scientists are banking various samples from recipients of donated uteruses to learn all they can about the biology of the organ, and about transplantation more generally.

For too long, a physiological inability to conceive or carry a child through to birth has been seen as a minor medical issue.

High altitude is a natural laboratory for investigating pregnancy complications such as preeclampsia and gestational hypertension that restrict a fetus’s oxygen supply.

Hearing others’ perspectives on infertility and pregnancy has me reconsidering my own reproductive journey.

Researchers propose a mechanism by which a protein produced in the placenta may trigger blood vessel growth and enlarge fat cells.

With human research trials resulting in dozens of successful deliveries in the US and abroad, doctors move toward offering the surgery clinically, while working to learn all they can about uterine and transplant biology from the still-rare procedure.

The microbiota helps align a mouse’s innate immune system with its feeding patterns, prepping the animal to fend off infection when it’s most likely to be eating.

Using deoxyoligonucleotides to bind proteins with high sensitivity and specificity

A new partnership opens the door for a source of highly purified human cell lines and defined cell culture media.

Not only is the humble fluid a boon for keeping humans cool, it also contains a wealth of biological information.

Automated control of light-responsive nematode worms marks the first foray into the development of multicellular, biorobotic organisms.

After eight weeks of exposure to ecologically plausible levels of methamphetamines, the fish tended to prefer meth-laced water over water without the drug.

Lab-grown cells from the reef-building coral Acropora tenuis provide new opportunities to study bleaching, symbioses, and biomineralization.

Stable, long-term cell lines will enable scientists to study everything from coral bleaching to biomineralization, knowledge that may help protect corals from ongoing climate change.

A study of 19 postmenopausal women found that eating a bar of chocolate in the morning affected their bodies differently than eating it at night, but neither led to weight gain.

A combination of approaches, including uterus transplantation and the joining of two animals’ circulatory systems, allowed males to bear pups, according to a preprint. But some experts say the experiments were not justified.  

The color morph’s bright yellow hue and its propensity for skin tumors both likely stem from a gene implicated in a dangerous form of human skin cancer, suggesting the animals could make an ideal model for studying the disease.
