A new study provides a thorough accounting of blood cell production from hematopoietic stem cells. The results are important for understanding disorders such as anemia, diseases of the immune system, and blood cancers such as leukemias and lymphomas.

A single allergic reaction during pregnancy prompts sexual-development changes in the brains of offspring that last a lifetime, new research suggests. Female rats born to mothers exposed to an allergen during pregnancy acted more characteristically 'male' -- mounting other female rodents, for instance -- and had brains and nervous systems that looked more like those seen in typical male animals.

Female birds age more slowly and live longer when they have help raising their offspring, according to new research from the University of Sheffield.

A new study in the Journal of Public Health finds that women in Norway from immigrant backgrounds are more likely to be overweight during pregnancy.

Scientists at the University of Cambridge have suggested that subtle changes to the drugs administered to mothers threatened with preterm birth or to premature babies could further improve clinical treatment and help increase their safety.

An international group of scientists under the supervision of a staff member of Sechenov University (Russia) and Karolinska Institute (Sweden) found out that earlier views on the mechanisms that provide and regulate skeletal growth were wrong. They discovered a special area of the growth plate (a structure that enables longitudinal growth of bones) called a stem niche that can theoretically produce infinite numbers of new cells. The article of the team was published in Nature.

Some studies have suggested that people who are younger when they enter puberty are more likely to later develop multiple sclerosis (MS). But a new study attributes that link to body mass index (BMI). The study is published in the March 20, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.
