A Toothpaste Cathy Would Love
I didn't think it could get any better than the day my dental hygienist told me that beer cleaned teeth (a fact I've never bothered to verify because I just don't want it to be wrong). But now it turns out that chocolate may be the best ingredient to add to toothpaste. A doctoral candidate at Tulane University has shown that cocoa extract is more effective at fighting cavities than fluoride, having done animal tests and developed a peppermint toothpaste with cocoa instead of fluoride. It could be another 2-4 years before the chocolate toothpaste is commercially available, and until then you should probably just stick to regular, foul-tasting paste; something tells me brushing with Hershey's and gargling with Yoo-hoo wasn't what he had in mind
Madly in Love
We've all heard that love makes us do crazy things, but we never realized how true that actually was. A scientist in Switzerland surveyed a group of adolescents and found that those who claimed to be in love actually exhibited signs of hypomania, a mild form of bipolar disorder. For example, the love-struck teens needed one hour less of sleep every night than their counterparts and were also twice as likely to say they had creative energy. The researchers concluded that adolescent love is a "psychopathologically prominent stage," and that psychologists should take this into account when treating teens. Anyone looking to study this subject more should look into the collected works of John Hughes.
Batteries almost always make devices twice as heavy as they need to be. However, a group of scientists from Rensselaer Polytechnic Institute and MIT have created a new technique of creating batteries that results in paper-thin power cells. The process is mighty complex, but the crux of it is in carbon nanotubes. As of now, the batteries are pretty weak, but they are able to fit in unusual shapes and could be made bigger and better. If they get more powerful, just imagine how thin cell-phones can be.

Use Fossil Fuels, Save the Earth
Yes, you read that headline correctly. As strange as it seems, some scientists around the world are presenting evidence that using biofuels won't do a whole lot to save the environment. A representative of the International Energy Agency says that creating biofuels will require cutting down forests to grow more corn, so, in the end, the net carbon reduction will be negligent. Scientists at the University of Leeds in Britain agree, saying that we wouldn't see any different for 50-100 years, which is far too long to wait. Instead, they are arguing that governments focus on replanting forests and making fossil fuels more efficient.
Space-age Stress Balls
Since no one can hear you scream in space, it must be difficult to figure out how stressed people are. And unlike in the easy-going world I live in, where I can easily go back and edit out stress-induced errors, stress for astronauts can cause costly and life-threatening problems (see: Mir Space Station). That's why NASA has designed a handheld device with a three-minute test to alert astronauts when they're too stressed to perform tasks.. The psychomotor vigilance task tests how quickly the subject can react to a flashing light to test sleep deprivation and mental fatigue. It will replace the ten-minute, multi-part test that includes pattern matching and repeating numbers that, while it sounds more fun, hasn't been effectively validated.
Dodo's Making a Comeback
The dodo was a flightless bird that laid its eggs on the ground and went extinct 400 years ago. But now we have a chance at studying its DNA, thanks to a discovery on an island off of Africa. Scientists looking for cave cockroaches stumbled upon a skeleton of a dodo that had been preserved nicely because of the environment in the cave. The discoverers theorize that the dodo, which they have christened "Fred," ended up in the cave because it had been trying to escape a storm and fell down a hole. If my wildest dreams come true, that means we could soon have a lame, dodo-filled version of Jurassic Park, which will assuredly make a less exciting movie.
Is the Fountain of Youth filled with Red Wine?
A professor at Harvard is purporting to be a modern-day Ponce de Leon with his research in resveratrol, a chemical he says can slow aging. David Sinclair says that resveratrol, which is found in red wine, extended the life span of mice by 24 percent and other animals by 59 percent. There's an understandable amount of skepticism around his research, but Sinclair says he believes the chemical could work on humans and has gathered a good deal of funding. Even though the research sounds exciting, I can't help but feel shades of the immensely unsettling Tuck Everlasting.
