The Tuvan throat-singing band Alash Ensemble has toured the world demonstrating both their cultural heritage as well as their vocal mastery. Their incredible ability to sing low and high notes simultaneously has inspired wonder and a deep appreciation for their craft. But how they achieve these otherworldly sounds hasn't been extensively explored. With the help of speech pathologist Aaron Johnson, we'll look inside the human vocal tract to see how these talented singers create their signature sounds.

Find out why this special ice cream stretches like silly putty. It's all in the molecules.

Carve first, scoop later--that's just one of the tips from Maniac Pumpkin Carvers Marc and Chris. Based in Brooklyn, these professional illustrators switch to the medium of pumpkin during October. They carve hundreds of pumpkins each fall, which go for a few hundred bucks and rarely end up on stoops. They gave us some tips for how to bring our pumpkins to the next level this Halloween.

BASE stands for the objects the practitioners of the sport jump from: buildings, antennas, spans, earth. Wingsuits are sometimes involved; parachutes, always. Luke Hively, who has racked up 2500 skydives and more than 150 BASE jumps, wondered about the physics of wingsuits. Physicists Leif Ristroph and David Hu weigh in. We wondered about the brain science of jumping off cliffs, and asked neuroscientist Chess Stetson about why time seems to slow down when we're scared.

Cuttlefish change the patterns on their body for courtship rituals, when they eat a snack, and most famously when they want to blend in. How they change their skin patterns may tell us something about how they see the world, says Duke biologist Sarah Zylinski. Her work suggests that when cuttlefish see incomplete shapes, they fill in the visual blanks -- much like humans do. Can't get enough saltwater camouflage? Watch: "Where's The Octopus?"

Electric eels zap fish and other underwater prey, but what would make them leap out of the water and shock an animal like a horse? Nineteenth-century naturalist and explorer Alexander von Humboldt first described eels emerging from the water to attack horses, and now Kenneth Catania of Vanderbilt University uses some unique props to reveal shocking insights about the behavior.

Despite their speed and power, Avalanches are not entirely unpredictable forces of nature. Using field tests and deep understanding under how to identify weaknesses in the snow pack, staff from the Utah Avalanche Center forecast avalanches and take preventative measures.

Typographer and illustrator Craig Ward heard an urban legend that "using the handrails on the subway is like shaking hands with 100 people." He decided to test that theory by sampling the bacteria on subway lines around New York City and photographing his findings. The results were striking and unconventional "portraits" of NYC commuters.

The guests at the WorMotel check in with a plop. Each guest has a private room, cozy and controlled temperatures, and enough food to last a lifetime. There’s just one catch: They can never leave. Featuring a silicone plate with an array of 240 wells that host tiny nematodes, the WorMotel is the creation of researchers in the Fang-Yen Lab at the University of Pennsylvania. Researchers to study thousands of the worms at a time in the hopes of revealing which of their 20,000 genes control aging.

For USGS wildlife biologist Karyn Rode, tracking and tranquilizing polar bears from a helicopter are just the first thrilling steps in her research. After acquiring various samples from sleeping bears, Dr. Rode's unique understanding of what they eat and how quickly they metabolize nutrients allows her to determine the condition of each bear. Working with a team of scientists from the US Fish and Wildlife Service for nearly a decade, Dr. Rode's monitoring of polar bear health has helped reveal how well populations are adapting to the rapidly warming Arctic.

We expect that our clothing won't tear or fade after one wearing and its dyes won't bleed in the wash. But confidence in our clothing shouldn't be taken for granted. It owes much to an oft-overlooked field of study - textile quality assurance. Professor Sean Cormier of the Fashion Institute of Technology details the rigorous yet fun tests that ensure your clothing doesn't just match your aesthetic standards - but meets a universal criteria for durability, color-fastness, construction and safety.

In 2014, Manhattanhenge will be on May 29-30 and July 11-12. Find out more info on the American Museum of Natural History's site: http://www.amnh.org/our-resear....ch/hayden-planetariu

Twice a year, the sunset lines up with New York City's street grid -- making for spectacular views. Neil deGrasse Tyson, director of the Hayden Planetarium in New York, identified the cosmic event over a decade ago and coined it Manhattanhenge. In this video from 2009, we watched the sun from 42nd Street, along with about 50 other astronomical enthusiasts.

MC Frontalot, aka Damian Hess, makes a living rapping about data encryption, rare diseases, video games and the nerd life. When we stopped by his Brooklyn apartment, Frontalot described Nerdcore, his name for the genre, as "the inversion of the shame of geekery... into pride." Dr. Awkward, a California-based nerdcore rapper, says that people assume nerd rap is a joke: "But it's not really about the juxtaposition of those two worlds -- nerdiness and hip-hop -- it just happens to be nerds expressing themselves through hip-hop."

Creating the scintillating scents and sensations of a perfume presents a lesson in molecular chemistry and craftwork. With the help of the Institute of Art and Olfaction, we'll take you on tour of how perfumes are made and how they can be creatively scattered for artistic means.

Scientists are experimenting with pumping CO2 deep beneath the sea floor. See the borehole where they practice.

A hawk moth (Manduca sexta) feeds by hovering in front of flowers and slurping nectar through a proboscis, basically a body-length straw. To understand how these moths keep such a precise position in the air, Tyson Hedrick, a biomechanist at the University of North Carolina at Chapel Hill, tried destabilizing moths in a variety of different ways and tracked their responses using high speed cameras.
