    How to build a human brain

    In a white lab coat and blue latex gloves, Neda Vishlaghi peers through a light microscope at six milky-white blobs. Each is about the size of a couscous grain, bathed in the pale orange broth of a petri dish. With tweezers in one hand and surgical scissors in the other, she deftly snips one tiny clump in half.

    Even brain images can be biased

    An astonishing number of things that scientists know about brains and behavior are based on small groups of highly educated, mostly white people between the ages of 18 and 21. In other words, those conclusions are based on college students.

    Animal study reveals how a fever early in pregnancy can cause birth defects

    Certain birth defects of the face and heart can occur when babies’ mothers have a fever during the first trimester of pregnancy, a crucial time in an embryo’s development. Now scientists have figured out the molecular players that make it so.  

    In an experiment with chicken embryos, a temporary rise in incubation temperature — meant to mimic feverlike conditions — was enough to produce...

    Birth control research is moving beyond the pill

    Mention “the pill,” and only one kind of drug comes to mind. The claim that oral contraceptives have on that simple noun testifies to the pill’s singular effect in the United States. Introduced in 1960, the pill gave women reliable access to birth control for the first time. The opportunity to delay having children opened the door to higher education and professional careers for many women....
