Routine mammography screening, widely considered crucial in early breast cancer detection, may in fact be doing its job too well.

It turns out that as many as a quarter of the early cancers detected by mammography would not progress. That suggests early detection results in a great deal of unnecessary treatment and stress, according to a Harvard School of Public Health analysis of a nationwide screening program in Norway.

"Radiologists have been trained to find even the smallest of tumors in a bid to detect as many cancers as possible to be able to cure breast cancer," lead … Read more

Japanese researchers led by Masaharu Komori, an associate professor of mechanical engineering at Kyoto University, recently demoed the Permoveh, or Personal Mobility Vehicle, as a prototype next-generation wheelchair.

The Permoveh has four wheels of the same size, and each wheel contains 32 rollers that can rotate in a perpendicular direction to the rim. As the vid below shows, the vehicle can move in any direction when the user operates a hand-held control.

When the user wants to travel forward or back, the wheels alone move; when going sideways, the rollers move. When traveling diagonally, both wheels and rollers move. … Read more

A law passed late Monday in Israel is not only banning underweight models from appearing in local advertising, it's also requiring publications to disclose when models -- male or female -- have been digitally edited to appear thinner than they are.

"We want to break the illusion that the model we see is real," Liad Gil-Har, the assistant to the law sponsor, told the Associated Press.

Supporters of the law, which appears to be the first of its kind anywhere, say they hope it will help reduce the rate of eating disorders, which in many developed countries (… Read more

Former Sun CEO Jonathan Schwartz says the idea for a health care site like CareZone had been germinating for about a decade.

But it wasn't until two years ago that he had some time to really devote to it. It was then that he and his good friend Walter Smith, one of the creators of the Apple Newton, sat down to talk about how they could make a difference in the lives of people who are caring for elderly parents or for children who have issues--people who want a safe place to store medical records and share access to … Read more

Health care can be difficult to access for rural residents in the developing world. San Francisco startup Medic Mobile is working to change that, by providing communications tools to doctors, patients, and community health workers.

Many of us have never been properly trained on how to do or use certain things we really should be good at. Putting on condoms and installing infant car seats are just two skills that come to mind; when we get them wrong, the health consequences can be grave.

The same can be said for improper asthma inhaler use--a serious and expensive problem considering some 5,000 people visit the emergency room due to and 11 people die from asthma every day, according to the Asthma and Allergy Foundation of America. Let's face it: some devices could use training wheels.

Enter the T-Haler, a digital asthma inhaler training device developed by researchers at Cambridge Consultants. Patients can use the inhaler and, via interactive software linked to the wireless device, get real-time visual feedback on the areas that need improving.… Read more

In an effort to quickly and efficiently map the roughly 5,000 automated external defibrillators (AEDs) in public areas of Philadelphia, researchers at the University of Pennsylvania's Perelman School of Medicine recently launched a contest to award $10,000 to the team or person who finds the most.

With the six-week contest, which kicked off in late January, nearing its March 13 deadline, researchers are already planning to conduct a similar, nationwide challenge.

AEDs can save the lives of those suffering cardiac arrests via electric shocks, particularly if used in the first minutes following the onset of the attack. … Read more

From the age of dot, we're all told not to put gadgets in our mouths.

But along came electric toothbrushes--and then electronic cigarettes. Some will wonder how safe they might be after a 57-year-old Florida man was taken to hospital Monday night when his electronic smoke exploded while he was smoking it.

He ended up in an Alabama hospital, facing burns, the loss of part of his tongue and his front teeth.

Joseph Parker, division chief for the North Bay Fire Department, offered a graphic analogy to the Associated Press: "It was trying to hold a bottle rocket in your mouth when it went off. The battery flew out of the tube and set the closet on fire."… Read more

After taking second place in the 2011 Imagine Cup finals, Team Lifelens of the U.S. is one of four teams from around the world to win a $75,000 Imagine Cup grant, Microsoft announced today at the World Economic Forum annual meeting in Davos, Switzerland.

The Lifelens project is run by students at universities across the country who have been working since November 2010 on an app that can image malaria cells for fast diagnosis right there on the phone, sans Internet.

The premise is straightforward. Apply a blood sample to a slide with a dye that only malaria … Read more
