Based outside of Seattle, Valid Cycles specializes in handcrafted bamboo bicycle frames. For bamboo to be bike-ready, it must be cooked in an oven, stripped, and sealed. But after that, the founders of Valid Cycles say the bikes last as long as metal ones. We stopped by their workshop -- a barn in Woodinville, Washington -- to see how the bikes are put together.

Deep below the sea surface, giant squid fight off predatory sperm whales--stirring legendary tales of epic battles. Yet for all it's infamy, discovering how many of these enormous cephalopods are lurking in the ocean has remained impossible...until now. Using simple arithmetic, Elizabeth Shea, Curator of Mollusks at the Delaware Museum of Natural History, along with colleagues at the Smithsonian Institution try to solve the mystery – with unfathomable results!

It's small. It's striped. It's looking for love. Meet the lesser Pacific striped octopus. Full-time biologist—part-time cephalopod matchmaker, Richard Ross invites us into his secret home lab where he studies the mating rituals of these tiny cephalopods.

Reporting in Science, Gabriel Villar and colleagues say that tiny water droplets can be engineered to work together sort of like cells -- moving in concert, passing electrical signals. Villar built a machine that fabricates these pseudo-cellular networks while he was getting his Ph.D. in the departments of chemistry and physics at Oxford. He says that water droplet networks (with some major advancements) could be made into artificial tissues.

Bridging the Rift: Oculus' Answer to Virtual Reality-- With their clunky designs and nauseating displays, truly immersive virtual reality devices used to be the stuff of science fiction—think The Matrix or Tron. However, recent technological and design advances by Oculus VR allow for dynamic and enjoyable virtual reality experiences (in the real world). Oculus VR’s founder, Palmer Luckey, details some of the key innovations inside the company’s headset, the Rift, and explains why virtual reality is finally ready for a mass-market debut.

Within sight of the famous New York skyline, you might see something unexpected—whales. Vast schools of menhaden baitfish swirl in the New York Bight, just a few short miles from downtown Manhattan, luring numerous whale species to feed.. Although breathtaking sights like these were unheard of just a decade ago in the waters off New York City, scientists say they signal a wildlife resurgence underway. Howard Rosenbaum, senior scientist for the Wildlife Conservation Society, explains why the whales have returned and how researchers are tracking the phenomenon in real time.
NOTE: The minke whale photo featured in this video is the dwarf minke whale, a subspecies not found in New York waters.

As part of Doug Emlen’s biology lab at the University of Montana in Missoula, Jillian del Sol was no stranger to bug battles. Year after year, study after study, species after species, students in Emlen’s lab have revealed the dramatic effects of sexual selection on male biological weaponry. So when she travel to East Asia to witness the tree trunk battles of the rhino beetles as part of her Ph.D. research, she came prepared to document the ecological conditions that influence chitinous combat. To her surprise, the successful male beetles didn’t just claim their prize after ousting their foes. Instead, they began to sing- or rather chirp and chitter at the females. This acoustic courtship continued even as they mated. Clearly, there was more to this mating system than just an escalating arms race between males. Now equipped with 150 beetles from field sites from Japan, del Sol aims to record these acoustic mating rituals in detail to hopefully discover why this bruiser bug suddenly turns from fighter to lover.

Bacteria and viruses hitch a ride inside droplets of all kinds—sneezes, raindrops, toilet splatter. By reviewing footage of different types of drops, applied mathematician Lydia Bourouiba records and measures where they disperse in order to better understand how diseases spread. Watch how Bourouiba designs tests—some inescapably humorous and awkward—to study infectious disease transmission.

By 1982, fewer than two dozen California condors lived in the wild. By 1985, only one wild breeding pair was known to exist. That's when the U.S. Fish and Wildlife service decided to capture any remaining condors and bring them to live--and breed--in captivity. The Peregrine Fund, in Boise, Id., houses the largest California condor breeding center in the U.S.--with nearly sixty California condors living on site. Bill Heinrich and Taiana Carvalho take us "behind the enclosure" for a tour of the condor compound.
Given their outlandish names and traits, imaginary companions might be dismissed as nostalgic relics of our ephemeral youth. Yet, research by psychologists has revealed that imaginary companions can provide glimpses into the development of critical creative, social, and cognitive skills of children. In the third episode of The Real Guide to Imaginary Companions, we'll see how developmental psychologist Tracy Gleason uses imaginary companions to study how children form relationships. We'll also learn how developmental psychologist Stephanie Carlson tests the role of pretend play, such as creating an imaginary companion, in a child's ability to exercise self-control.

Think oysters are good on the half shell? They may be even better whole. Oysters can restore marine habitats by cleaning water, creating homes for other sea life and preventing coastal erosion. But oyster populations around the world have declined, experts say. Find out how scientists in New York are working to replenish oyster populations in the waters around the city.
In perhaps the cutest study published in the Proceedings of the National Academy of Sciences, psychologist Marcel Zentner and Tuomas Eerola found that babies will spontaneously boogie when they hear music and other rhythmic sounds. The findings suggest babies are not great dancers, but they smile more when they do hit the beat.
An elephant shrew is neither an elephant nor a shrew and has a manatee for a close relative. It's more like a mix between a miniature antelope and anteater. Researchers recently discovered a new species of elephant-shrew in Tanzania
