Researchers have identified a group of nerve cells in the mouse brain that are involved in creating negative emotional states and chronic stress. The neurons, which have been mapped with a combination of advanced techniques, also have receptors for estrogen, which could explain why women as a group are more sensitive to stress than men.

New research analyzed data from 11 studies of over 5,000 women around the world between 1980 and 2021, to evaluate how common it is to get pregnant naturally after having a baby conceived by fertility treatment. Around 20% of women who needed fertility treatment, such as IVF, to conceive their first child are likely to get pregnant naturally in the future, finds a new study.

Researchers have used an algorithm from a video game to gain insights into the behavior of molecules within live brain cells. Researchers used coding tools to build an algorithm that is now used by several labs to gather rich data about brain cell activity. The algorithm was applied to observe molecules clustering together -- which ones, when, where, for how long and how often.

Newborns delivered by cesarean section who are swabbed with the vaginal fluid of their mothers after birth have beneficial bacteria restored to their skin surface and stools, according to a new study. In the first randomized study of its kind, a team of researchers found the process, known as vaginal seeding, definitively engrafted new strains of maternal bacteria in the babies' bodies.
