To define the boundaries of peripersonal space, the researchers asked blindfolded participants to push a button as soon as they felt a light tap on the abdomen. Their... Read More
Umbilical cords tie mother and baby together, if only for a brief spell. But the stuff inside these cords has the potential to be useful well after birth. Cells in umbilical cord blood are already being used to treat certain diseases, including... Read More

Ultrasounds during pregnancy can be lots of fun, offering peeks at the baby-to-be. But ultrasounds aren’t just a way to get Facebook fodder. They are medical procedures that involve sound waves, technology that could, in theory, affect a growing... Read More
For mice, birth mode matters when it comes to weight. Within their first years of life, pups born by C-section gained more weight than mice born vaginally, researchers report. Scientists attribute this heft to different microbiomes — the communities... Read More
Words can’t describe the pandemonium that follows a child’s birth, but I’ll try anyway. After my first daughter was born, I felt like a giant had picked up my life, shaken it hard, martini-style, and returned it to the ground. The familiar objects... Read More
