Researchers have found that the oft-maligned banana peel can grab heavy metals out of polluted water.
Banana peels don't get a lot of respect. Though we here at Shots have never actually heard of anyone slipping on one, it seems they're stuck in the cultural lore as a nuisance, or even a hazard.
But a Brazilian researcher, who also happens to be a banana lover, has taken an interest in the lowly banana peel and is helping to remake its image. The banana peel, it turns out, can take water dirtied by heavy metals from mining operations or other activities and turn it to clean drinking water.
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.
A nationally known priest who participated in a ceremony in Kentucky ordaining a woman is refusing to recant his views despite pressure from his order and the Vatican. Rev. Roy Bourgeois was excommunicated by the Roman Catholic Church in 2008 for taking part in the ordination of Janice Sevre-Duszynska. Since that time, he's continued his affiliation with Maryknoll Fathers and Brothers but remains staunch in his support for the ordination of women. Mike Virgintino, communications manager for the order, said, "Maryknoll has tried to foster dialogue regarding this issue and now it's come to a time when Maryknoll can do no more."
Is the tea party movement shrinking? According to a recent New York Times poll, support for the tea party is at 18 percent, the lowest level since April 2010, before a wave of tea party candidates was elected in November and sent to Washington, D.C. Paul Keith, chairman of the local Bowling Green/SOKY Tea Party, said while the majority of local tea party supporters weren’t in favor of the debt deal reached in Washington last week, it hasn’t translated into a dip in support.
The Kentucky State Park system is taking part in the Coca-Cola “America is Your Park” campaign and is asking for people to vote for Cumberland Falls State Resort Park. The campaign encourages people to play, be active and to help give their favorite park a facelift.
Three lawmakers who are typically forceful advocates for a progressive agenda were picked by Rep. Nancy Pelosi to fill out the supercommittee that will propose more than $1 trillion in federal spending cuts meant to reduce federal deficits.
Pelosi, the House minority leader, chose representatives Jim Clyburn of S. Carolina, Chris Van Hollen of Maryland and Xavier Becerra of California to represent House Democrats on the Joint Select Committee on Deficit Reduction.
