Why some women hobble without heels?

Women who routinely wear high heels may feel pain when they don flats because regularly walking around with their heels elevated can significantly change leg muscle structure — causing the calf muscles to shorten and tendons to stiffen — according to a study published online today in The Journal of Experimental Biology.

Report: fetus cannot feel pain before 24 weeks

A new report from the U.K.’s Royal College of Obstetricians and Gynaecologists (RCOG) concludes that, before 24 weeks, nerve endings in the brains of fetuses aren’t sufficiently developed to experience pain. The findings, based on a review of recent studies examining fetal development and capacity for pain, undermine the argument for a

When tots need shots, a dose of sugar to dull the pain

When given a small amount of sugar beforehand, babies are less likely to cry when receiving injections, according to new research published in the May 12 issue of the Archives of Disease in Childhood. A team of researchers from Canada, Australia and Brazil reviewed 14 studies examining how a boost of sugar affected pain experienced by

Spicy research: peppers may help burn calories

Peppers are having a big week. Researchers at the University of California, Los Angeles’ Center for Human Nutrition say that preliminary findings from a small study suggest that the chemical that gives spicy peppers their kick, capsaicin, may not only make you sweat when digging in to a hot dish, but may actually prompt your body to

Not coping with stress may increase teeth-grinding

People who are stressed are more likely to grind their teeth in their sleep—clenching, and working their jaws throughout the night, slowly wearing teeth smooth or even chipping them, and awakening with headaches and muscle tension. Yet, according to new research published last week in the journal, it’s not solely feeling stressed, but

Migraine treatment with a magnetic pulse

Administering a small magnetic pulse to the back of the head may be an effective, and drug-free, method for combating migraine pain, according to new research published online this week, and in the April issue of the journal Lancet Neurology. Previous research has suggested that this single-pulse transcranial magnetic stimulation (sTMS)

Trial run: testing the barefoot running trend

I don’t particularly enjoy running. On the other hand, I don’t particularly enjoy being overweight and out of shape either, so I do it — usually about three times a week, depending on my work schedule and willpower. But over the years I’ve developed chronic soreness in my knees and lower back, which I attribute at least in …

I really do feel your pain

A new study published in the journal Pain suggests that sympathizing with others’ discomfort may be entail more than kind words, and that for some people, witnessing others in pain actually does light up parts of the brain associated with pain-processing. Researchers at the University of Birmingham in England recruited 108 college

Oxycontin-related deaths spike in Canada

Between 1991 and 2004, deaths due to opioid overdose more than doubled in Ontario, an alarming trend that corresponds with an increase in prescriptions for oxycodone, a narcotic pain killer derived from extracts of opium. What’s more, the introduction of oxycontin—a long-acting form of oxycodone—in 2000, was associated with a
