In developing countries, a new, inexpensive treatment allows nurses to spot pre-cancerous lesions on a woman's cervix and remove them—without needing a medical lab, and without surgery. It has huge implications for women's health, because cervical cancer kills 250,000 women every year.
In fact, before pap smears became commonplace, cervical cancer killed more American women than any other sort of cancer. But in places where the pap smear isn't practical, this new technique can help. From the New York Times:
Nurses using the new procedure, developed by experts at the Johns Hopkins medical school in the 1990s and endorsed last year by the World Health Organization, brush vinegar on a woman’s cervix. It makes precancerous spots turn white. They can then be immediately frozen off with a metal probe cooled by a tank of carbon dioxide, available from any Coca-Cola bottling plant.
... Dr. Bandit Chumworathayi, a gynecologist at Khon Kaen University who helped run the first Thai study of VIA/cryo, explains that vinegar highlights the tumors because they have more DNA, and thus more protein and less water, than other tissue.
It reveals pre-tumors with more accuracy than a typical Pap smear. But it also has more false positives — spots that turn pale but are not malignant. As a result, some women get unnecessary cryotherapy. But freezing is about 90 percent effective, and the main side effect is a burning sensation that fades in a day or two. By contrast, biopsies, the old method, can cause bleeding.

That point of light between Saturn’s rings is Earth, captured by NASA’s Cassini spacecraft on April 12. More about the image here at NASA JPL. It reminds me of the last photo taken by the Voyager I spacecraft before engineers shut off its imaging systems. Carl Sagan had persuaded NASA to turn Voyager I’s cameras […]
As AI improves, the mystery of consciousness interests more programmers and physicists.
Most of us need a computer interface implanted in our brains like we need a hole in our head. That said, there are benefits to bridging the gap between mind and machine. Joel Murphy is the founder of OpenBCI, an inexpensive, and non-invasive, brain-computer interface (BCI) platform. People have used OpenBCI to control robots, compose […]
Even the most expensive pair of hi-fi headphones can’t match the feeling of bass rumbling through your body at a live show. That’s why music aficionados designed The Basslet, an accessory that reproduces that sensation from your wrist. Does it make your whole body shake with deep subs? Not really, because that would be terrifying, but […]

Thinking of a business idea is the easy part. Doesn’t even have to be a “good” idea, you can still get people to throw money at a non-existent venture, but to do that you need to at least have something even resembling a viable business plan. Why doesn’t anyone do it then? Because building that semi-viable […]
