A new type of sensor uses flat, flexible electronics printed on a thin rubbery sheet, which can stick to human skin for at least 24 hours.
Researchers have created a new thin flexible sensor that can be applied with water, like a temporary tattoo. Measuring activity in the brain, heart and muscles, the innovation could cut down on the number of wires and cables medical personnel use to monitor patients, among other applications.
The electronics can bend, stretch and squeeze along with human skin, and maintain contact by relying on "van der Waals interactions" — the natural stickiness credited for geckoes' ability to cling to surfaces.
As the Republican presidential hopefuls converge on Iowa this week for Thursday night's debate and Saturday's influential straw poll, we caught up with Republican strategist Marc Lampkin, deputy campaign manager for George W. Bush's 2000 presidential bid and a former staffer to Rep. John Boehner (R-OH) years before he became House speaker. His thoughts on the unofficial kickoff to the GOP primaries:
Walking can actually be good medicine for osteoarthritis.
People with osteoarthritis in their knees aren't getting much exercise, a new study finds, even though exercise actually helps reduce pain and stiffness and can prevent future disability. What kind of exercise would help beat the pull of the couch? Try walking and swimming, doctors say.
It's not a huge surprise that exercise doesn't appeal to people with arthritis. Who wants to run with aching knees? It's human nature to want to coddle aches, not exorcise them.
The Swiss franc has reached all-time highs against the euro and the dollar this week as nervous investors seek a safe haven. But the rapidly rising Swiss currency threatens to harm key parts of the Swiss economy, including exports and tourism.
Switzerland is in danger of becoming a victim of its own success. While much of Europe is swamped by debt, massive unemployment and political turbulence, Switzerland's economy has been humming along nicely.
That's starting to cause problems in the form of its super-strong currency. The Swiss franc has become like gold, with investors snapping up francs as a hedge against the debt crisis in the eurozone and the volatility of financial markets worldwide.
