The $1.455 billion “All of Us” project that the National Institutes of Health is launching this spring stands on the shoulders of the $3 billion Human Genome Project, which was (mostly) completed in 2003. All of Us will collect DNA, health, lifestyle, and other data from 1 million Americans to, among other things, identify the genetic and environmental roots of disease and understand why different people respond differently to the same drug. The genome project, which determined the sequence of most of the 3 billion biochemical “letters” that spell out human DNA, had similar goals. Some have been realized, others not. (Begley, 4/2)

Stress from dealing with racism and sexism seems to be a key reason that highly educated black women are far more likely lose their babies than are equally educated white women, says Keisha Bentley-Edwards, a co-author of a new report, which is titled “Fighting at Birth: Eradicating the Black-White Infant Mortality Gap.” The stress can lead to premature delivery of low birth-weight babies.

Babies given antibiotics or antacids in infancy may be at increased risk for allergies in childhood. Researchers retrospectively studied 792,130 infants covered by a health insurance program. Of these, 131,708 received antibiotics, 60,209 got histamine-2 receptor antagonists and 13,687 were given proton pump inhibitors. Both H2 blockers and P.P.I.s are prescribed for gastroesophageal reflex, or GERD. (Bakalar, 3/2)

Myrtle Beach , South Carolina, has a busy boardwalk and all kinds of attractions, from mini-golf courses and water parks to a zip line and a Ferris wheel. So it might not be an obvious destination for families with kids on the autism spectrum who may be easily overwhelmed by noise and commotion. But an organization called Champion Autism Network is working with hotels, restaurants and other venues to make the area autism-friendly. (Harpaz, 4/2)

Every week in Murfreesboro, Tenn., Zibin Guo guides veterans in wheelchairs through slow-motion tai chi poses as a Bluetooth speaker plays soothing instrumental music. "Cloudy hands to the right, cloudy hands to the left," he tells them. "Now we're going to open your arms, grab the wheels and 180-degree turn." The participants swivel about-face and continue to the next pose. Guo, a medical anthropologist at the University of Tennessee at Chattanooga, has modified his tai chi to work from a seated position.

You’re feeling depressed. What have you been eating? Psychiatrists and therapists don’t often ask this question. But a growing body of research over the past decade shows that a healthy diet—high in fruits, vegetables, whole grains, fish and unprocessed lean red meat—can prevent depression. And an unhealthy diet—high in processed and refined foods—increases the risk for the disease in everyone, including children and teens. (Bernstein, 4/2)

Baby boomers, determined to keep moving no matter what wear and tear and arthritis have wrought, are fueling a surge in joint replacements. Taking advantage of improved artificial joints and surgical methods, aging Americans are getting so many new hips, knees, shoulders, and ankles that orthopedic surgeons are having trouble meeting the demand.

Imagine uncoiling a condom and stuffing it up one side of your nose, then plugging the other nostril and inhaling until the long piece of latex slides into your throat. Then what? You reach back and pull it from your mouth. Why would someone do that?Apparently for the same reason young people have dared each other to pour salt in their hands and hold ice until it burns, douse themselves in rubbing alcohol and set themselves on fire, or bite into colorful liquid laundry detergent packets.

April is Parkinson’s Disease Awareness Month, a time to think about how much you know about the disease. You may know about the tremors and stiffness that gradually take over patients’ bodies. You may know about famous people with the disease, including Michael J. Fox. For what you may not know, there’s the PD Library. (Blakemore, 4/2)
