Engineer George Lewis would like to move the soothing pain relief of ultrasound out of the doctor's office and into your medicine cabinet. The biomedical engineering student, who is about to receive his doctorate from Cornell University in Ithaca, N.Y., is working on a coin-size device to make ultrasound pain relief available any time, anywhere. Doctors and physical therapists use ultrasound for pain relief for conditions such as muscle spasms, tendonitis, osteoarthritis and sciatica.

For veteran Emily Cook, the Olympics have been a case study of pain management. The 30-year-old freestyler from Park City, Utah, has been dealing with the lingering pain of a bruised left heel, which has limited her practice time at Cypress Mountain. She will test it on Saturday morning in qualifying for women's aerials. The favorites in the competition include Nina Li of China, her countrywoman Mengtao Xu and Lydia Lassila of Australia. Li was the silver medalist four years ago in Turin.

Researchers at USC have made mice insensitive to near-freezing temperatures by deactivating select neurons, a development that could one day lead to new treatments for pain in humans. In a study published Tuesday in the Journal of Neuroscience, researchers used a bacterial toxin to kill neurons equipped with so-called TRPM8 channels, cellular structures that help relay sensations of cold. (The pathway is also responsible for sensing menthol, the cooling component of mint.) Neurons that sense heat and mechanical pain were left intact, however.

It's taken an army of mice (and a group of clever Canadian researchers) to crack open an old sexual chestnut and get at the meat inside: For women, "Not tonight dear, I have a headache" is not a passive-aggressive rebuff to a mate's sexual invitation (not always, at least). It's a biological phenomenon with deep evolutionary roots. Even for females who've never watched a 1950s movie or been schooled in the art of sexual gamesmanship, bodily pain puts a serious damper on sexual desire, new research has revealed.

Rafael Nadal would be the first to say he's coming back from sore knees and it's no big thing. Richard Gasquet would be the first to say he's coming back from a raw deal and it's a huge thing. The two young tennis stars played a first-round match on center court at the U.S. Open on Wednesday. Nadal won, as expected. Gasquet showed flashes of brilliance in the 6-2, 6-2, 6-3 defeat, as expected. But this was much more than your routine match. This one had connections, multiple story lines and an off-court soap opera.

Nobody wants to be bitten by a black mamba. One of the most dangerous snakes in the world, its venom can kill a person in less than half an hour. But a new study reports that there is something besides deadly toxin hidden inside the snake: a powerful painkiller that works as well as morphine but without the side effects. In the report, published Wednesday in the journal Nature, researchers from France described two previously unknown pain-killing peptides extracted from the mamba toxin.

The other day, my 9-year-old son came in from throwing the football with his dad, sobbing in pain. My husband told me that he'd twisted his neck when he went out for a long pass; he assured me that there'd been no rough tackles or hard falls. I was initially sympathetic, dispensing a hug and comforting words. It was only when my son insisted that he couldn't possibly eat dinner at the table and needed to be served on the couch that I started to laugh. I had no doubts that his neck hurt him; in fact, I was sure that it did. But as a doctor, I was convinced that it was a minor injury, probably a muscle strain that couldn't hurt too badly.

Many people who suffer with lower back pain rely on glucosamine supplements for some relief. But does the stuff really work? A new study shows that glucosamine was no different from a placebo in treating lower back pain. The study, released Tuesday in the Journal of the American Medical Assn., was a large, double-blind, randomized placebo-controlled trial that included 250 adults with chronic lower back pain. It was conducted at the Oslo University Outpatient Clinic in Norway. Chronic lower back pain plagues millions of people in the U.S., and treatments include physical therapy, medication and the use of glucosamine supplements.

Massage therapy may hit the spot for people suffering from low back pain. A recent study in the journal Annals of Internal Medicine found that two types of massage--relaxation and structural--improved function and pain for people with low back pain, compared with regular treatment. The study included 401 men and women age 20 to 65 who had nonspecific lower back pain. Two-thirds were randomly assigned to two types of massage: relaxation, or Swedish, massage, non-therapeutic massage not intended for helping with pain; and structural massage, which often concentrates on soft tissue and pain issues.

You've been dumped by a romantic interest you really liked. You've been passed over for a job by a boss you thought admired you. A group of friends is going out together, leaving you out of their plans. This kind of social rejection prompts your brain to send warning signals to your body that there's been a sudden tear in your personal social fabric, says a new study. Some of those signals you will undeniably feel -- the pain in your gut, the ache in your heart, the lump in your throat.
