Ancient human teeth can tell us a lot. Hidden inside each set are clues about their owner's behavior and ancestry plus hints about what really made up the paleo diet. Shara Bailey, associate professor of anthropology at New York University, reads the topography of teeth to better understand the origins and lineages of humans. You can even test your own teeth to see if you have the same bumps and grooves as your ancestors.

With their pungent aromas and vibrant blooms, orchids lure insects, green-thumbs, and romantics alike. Marc Hachadourian, the New York Botanical Garden's curator of orchids, describes some of the deceptive methods orchids use to manipulate species into becoming their pollinators.

For centuries, maple syrup producers across New England and Canada harvested sap by drilling into the bark of fully grown wild trees. While commercial syrup producers have adopted vacuum pumps and plastic tubing to aid these efforts, recent experiments at the University of Vermont's Proctor Maple Research Center may further pull the industry from its pastoral roots. By vacuum-sucking sap directly from the cut tops of juvenile trees, the researchers increased syrup production 5 to 6 times per acre compared to the traditional sap collecting methods.

Tucked into the midtown Manhattan headquarters of the General Society of Mechanics & Tradesmen of the City of New York, is the John M. Mossman Lock Collection. The locks and assorted items, most which were collected and donated to the museum by Mossman, show the evolution of bank and vault lock technology through the 19th and 20th centuries. The current curator of the locks, John Erroll, describes the collection and its significance.

Eight days after the full moon, scientists from the University of Hawaii’s Cnidarian Venom Lab comb Waikiki beach collecting deadly tourists to bring back to their lab. They'll use these box jellyfish specimens to study their venom and help generate a chemical blocker to mitigate the fatal effects of the jelly’s sting. . Killing more humans per year than sharks, the box jellyfish is one of the deadliest creatures on earth. Dr. Angel Yanagihara and her Cnidarian Venom Lab have shown that . the widely accepted treatment combo of urine and ice can make the sting worse.

Back in 2012, Raul Oaida, 18-years-old, attached a LEGO shuttle, a video camera and a GPS tracker, to a huge helium balloon and sent them into space. Oaida says flight time was just about three hours and the shuttle reached an altitude of 115,000 feet before heading back to Earth. According to Oaida, designing the spacecraft wasn't so hard (compared to the jet engine he designed and built before this) but getting a flight clearance was.

Edith Widder has been exploring the deep sea for thirty years. When she descended for the first time, she turned off the lights of her submersible hoping to see marine organisms that make light--bioluminescent animals. Widder says she wasn't prepared for the light show she encountered and has been building tools to document bioluminescence ever since.

We stopped in at Columbia University for a quick fMRI.

The horn of a Japanese rhinoceros beetle (Trypoxylus dichotomus) can grow to be two-thirds the length of the rest of its body. And size matters. The male beetles use their horns to battle over feeding sites, where they also get access to female beetles. The longer the horn, the more reproductive success. So what limits horn-size? And why do some beetles have big horns and others puny ones? Biologists Doug Emlen and Erin McCullough of The University of Montana are looking into it.

Catfish attacking pigeons, water traveling uphill, a blue whale barrel roll -- it's amazing what you can find in the "supplemental materials" section of the scientific journals. We're taking a stroll down memory lane for a look at the year's best moments in science cinema. What were your favorite science videos of 2012?
