    Medicaid expansion may help shrink health gaps between black and white babies

    Black babies in the United States are twice as likely as white infants to be born at low birth weight, and 1.5 times as likely to be born prematurely. But states that expanded Medicaid health care coverage as part of the 2010 Affordable Care Act may be shrinking that racial health gap, a study finds.

    Researchers analyzed birth certificate data in 18 states plus Washington, D.C., that had...

    The learning gap between rich and poor students hasn’t changed in decades

    The average performance of the lowest income students in the United States lags about three to four years behind that of the highest income students — an achievement gap that has remained constant for more than four decades, a new study finds.

    An analysis of standardized tests given to more than 2.7 million middle and high school students over almost 50 years suggests that federal...

    Why it’s key to identify preschoolers with anxiety and depression

    The task was designed to scare the kids. One by one, adults guided children, ranging in age from 3 to 7, into a dimly lit room containing a mysterious covered mound. To build anticipation, the adults intoned, “I have something in here to show you,” or “Let’s be quiet so it doesn’t wake up.” The adult then uncovered the mound — revealed to be a terrarium — and pulled out a realistic looking...

    An ancient child from East Asia grew teeth like a modern human

    An ancient child with a mysterious evolutionary background represents the oldest known case of humanlike tooth growth in East Asia, researchers say.

    The child’s fossilized upper jaw contains seven teeth that were in the process of developing when the roughly 6½-year-old youngster died at least 104,000 years ago and possibly more than 200,000 years ago. Using X-rays to examine the teeth’s...

    Pregnant women’s use of opioids is on the rise

    Pregnant women aren’t immune to the escalating opioid epidemic.

    Data on hospital deliveries in 28 U.S. states shows the rate of opioid use among pregnant women has quadrupled, from 1.5 per 1,000 women in 1999 to 6.5 per 1,000 women in 2014, the U.S. Centers for Disease Control and Prevention reports.

    The highest increases in opioid use among pregnant women were in Maine, New Mexico...

    Human brains make new nerve cells — and lots of them — well into old age

    Your brain might make new nerve cells well into old age.

    Healthy people in their 70s have just as many young nerve cells, or neurons, in a memory-related part of the brain as do teenagers and young adults, researchers report in the April 5 Cell Stem Cell. The discovery suggests that the hippocampus keeps generating new neurons throughout a person’s life.

    The finding contradicts a...

    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.

    When growing human brains, sometimes you need to do some pruning.

    The...

    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.

    College students make a convenient study population when you’re a researcher at a university. It makes for a biased sample, but one that’s still...

  • 50 years ago, folate deficiency was linked to birth defects

    Folic acid

    Pregnant women who do not have enough folic acid — a B vitamin — in their bodies can pass the deficiency on to their unborn children. It may lead to retarded growth and congenital malformation, according to Dr. A. Leonard Luhby…. “Folic acid deficiency in pregnant women could well constitute a public health problem of dimensions we have not originally recognized,” he says...

    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...
