Endemic to the forests of south and southeast Asia, the silver-backed chevrotain, or Vietnamese mouse-deer, is one of the world's most elusive animals. The rabbit-sized critter is only known to science through five specimens, four of which were recorded by researchers in 1910. The fifth was killed by a hunter and donated to scientists in 1990. Since then, there have been no recorded sightings of the animals, leading many to fear they had gone extinct. Now, thanks to the efforts and persistence of a team led by biologist Andrew Tilker, the species has not only been rediscovered but also photographed in the wild for the first time!...

Unlike early space travelers, who had to consume mysterious powders, purees, and freeze-dried cubes, today's astronauts enjoy a variety of freeze-dried meals, snacks, and desserts that can be commonly found on Earth. However, delicious as the cuisine is, it pales in comparison to a freshly-cooked meal. Though the ability to cook an entire spread in space may take a few years, astronauts at the International Space Station (ISS) may soon be able to enjoy freshly-baked cookies, thanks to a newly-acquired space oven....

Most male birds try to attract mates with elegant gestures. Seabirds bob their heads and flutter their wings, while peacocks fan out their beautiful feathers. However, the white bellbird, endemic to the Amazon rainforest in Brazil, dispenses with the pleasantries and cut to the chase by shrieking in its prospective "date's" face at a deafening 125 decibels (Db)— the loudest bird call ever recorded. To put it in perspective, that is 40 Db higher than the safe hearing range for humans! Prior to this, the honor belonged to another Amazon-dweller — the aptly-named screaming piha — which has a peak recorded "song" volume of 116 Db....

Antibiotics — medications that destroy or slow down bacteria growth — are becoming increasingly less effective as the pathogens find new ways to evade the drugs. Some produce pumps that flush the antibacterial medicines out from the bacterial cell, while others modify themselves, so they are unrecognizable as targets. Now, researchers at UK's Newcastle University have recorded the germs shedding their outer skins and changing their shapes to avoid detection....

On October 20, 2019, Wing, a subsidiary of American multinational conglomerate Alphabet Inc., began the most advanced trials of commercial drone delivery in the US yet in Christiansburg, Virginia. Residents can now use a smartphone app to order items from Wing partners such as pharmacy giant Walgreens and local specialty chocolate and popcorn retailer Sugar Magnolia. A Wing drone will pick up the order and gently lower the package with the help of a tether outside the customer's door within an hour!...

Humpback whales spend summers feeding in the cold Arctic and Antarctic waters and then migrate to tropical waters during the winters to breed and give birth. Since they don't eat at all during this time, the mammals have to ensure they have enough fat reserves to feed their calves and to sustain themselves. To optimize their prey consumption, humpback whales often create circular "nets" with bubbles exhaled from their blowholes. Now, for the first time, researchers have captured detailed footage of the so-called bubble-net fishing technique from the whale’s point of view along with, an aerial video....

The Smithsonian's National Zoo in Washington, DC, is home to 2,700 animals representing more than 390 species. However, few are as beloved as giant panda cub Bei Bei, whose progress, from a frail newborn weighing less than a third of a pound to a healthy, 240-pound (109-kg) "toddler," has been eagerly followed by millions of fans both online and on-site. On November 19, 2019, America will bid farewell as its favorite panda cub departs for Chengdu, China, to join a cooperative breeding program to try to save his vulnerable species, which currently numbers just 1,864 specimens in the wild....

Ever since humans began venturing into space, 227 astronauts have left the spacecraft to perform some sort of extravehicular activity (EVA). While 14 of those have been women, the female astronauts have always been accompanied by a male counterpart. On October 18, 2019, US astronauts Christina Koch and Jessica Meir became the first all-female team to conduct a spacewalk to replace a failed battery controller....

Though not as mainstream as devices like smartphones and fitness trackers, more companies are now experimenting with the concept of connected garments. Among the pioneers is London-based CuteCircuit, which has been creating fashionable smart clothing since 2004. The company's latest innovation is the "Sound Shirt," which allows deaf people to "feel" live music by transforming the tunes into touch sensations in real time....
