Gates Foundation offers $100k for 'next-gen condom'

We're not quite sure what a next-generation condom would look like (gesture control? a tiny touch screen?), but we may find out sooner rather than later if the Bill and Melinda Gates Foundation succeeds in its new quest.

The foundation is seeking new ideas that improve on condom design, which it describes as having seen "very little technological improvement in the last 50 years." The winning proposal gets a cool $100,000, and could potentially earn more in additional funding.

The foundation suggests that if a redesigned condom could enhance a sexual experience and not detract from it, more men would use one, therefore reducing disease transmission, unwanted pregnancies, and so on. The request also seeks ideas "that increase ease-of-use for male and female condoms, for example better packaging or designs that are easier to properly apply. In addition, attributes that address and overcome cultural barriers are also desired." … Read more

New telemedicine tech maintains patient privacy

Here's the scenario: a mom has a baby recovering from an ear infection. He's doing fine, but the doctor wants to do a follow-up visit to make sure he took the antibiotics well and is on the mend. The problem is that it's a hassle for the mother to load the baby and her toddler into the car to drive an hour each way for a quick 15-minute visit. Here's a solution: telemedicine, or a video chat on a computer or tablet with a physician from the comfort of the family's home.

Such chats are … Read more

Trying to lose weight? DietBet puts your money where your cake-hole is

Everyone wants to lose weight, but for many folks, the rewards of looking better, feeling better, and living longer aren't sufficient motivation.

Ah, but what if there's money involved?

That's the idea behind DietBet, a "social dieting game" with a twist: You bet some money with friends and/or strangers, then spend 28 days trying to lose 4 percent of your body weight. Winner takes the pot -- which can end up being pretty sizable. If there are multiple winners, they split the cash.

In other words, here's your chance to lose weight and … Read more

Galaxy S4: Cool features, awful launch

CNET Update didn't expect Samsung to be sexist:

Samsung finally unveiled its flagship smartphone, the Galaxy S4. But this was no ordinary press conference. The Galaxy S4 presentation was a campy Broadway-styled spectacle that was painful to watch with sexist caricatures of women.

Despite the distasteful event, the Galaxy S4 will surely be a big seller and top rival to the iPhone. Today's video offers a quick explanation of the smartphone's new features, such as being able to navigate by waving a hand over the screen. (Many of these features will also come to Galaxy S3 users.) … Read more

Recon 2: The Google map of the human body

What if you could "street view" the human body, navigating its interactive components all the way down to a metabolic level? An international group of scientists is working on that right now with a map of the human metabolism, which they call Recon 2.

Metabolism plays a key role in many diseases, and while scientists have already managed to reconstruct several models of it, each "represents only a subset of our knowledge" with "only partially overlapping content," the team writes in the journal Nature Biology.

"It's like having the coordinates of all the cars in town, but no street map," Bernhard Palsson, a professor of bioengineering at the University of California San Diego Jacobs School of Engineering and one of the authors of the paper, said in a statement. "Without this tool, we don't know why people are moving the way they are."… Read more

Could goggles hold key to detecting strokes early?

Testing for strokes can be inaccurate and expensive. But a new device that looks like a pair of swimming goggles may offer a better, cheaper alternative, and save tens of thousands of lives every year.

The goggles, equipped with an infrared camera attached to a cord that goes to a laptop computer, measure eye movements, Dr. David Newman-Toker, an associate professor of neurology at the Johns Hopkins University School of Medicine, explained on "CBS This Morning."

"The eye movements (when) patients present with strokes in the back part of the brain -- and that's about one out of every four strokes -- the patients present with dizziness and vertigo and we can tell from their eye movements whether they've had a stroke or whether they have a benign inner-ear condition, quickly and easily," said Newman-Toker, who is leading the study of the new technique.

The goggles will work best as strokes occur, Newman-Toker said, and will likely find use in emergency rooms. … Read more

uBiome project to sequence the bacteria that live on us

Oxford University Ph.D. student Jessica Richman, who today finished raising some $350,000 from more than 2,500 people wanting to take part in the uBiome project, isn't shying away from reality: "Yes, we are going to be sampling people's poo," she told the Guardian this week.

And for the squeamish, she offered an asterisk: "You'll only have to wipe it on the toilet paper."

The uBiome project is a "citizen science" effort to sequence the genomes of the trillions of bacteria that colonize our bodies and likely play pivotal … Read more

1 in 3 people have gone online to diagnose a health problem

A fair number of people are turning to the Internet to help them with medical problems.

Among 3,000 adults surveyed by Pew Internet, 35 percent say they've gone online at one time or another to diagnose a medical condition. Some were researching their own medical problems, while others were looking into problems suffered by people they know.

Dubbed "online diagnosers" by Pew, 46 percent of them said the information they found online made them think they needed the help of a doctor. Another 38 percent said they felt they could remedy the problem at home, and … Read more
