Earth's Youngest Volcanic Island May Provide Interesting Insights Into Mars

When the ashes from a December 2014 eruption of a submarine volcano created a 400-foot (120-meter) island in the South Pacific Kingdom of Tonga experts predicted it would last a few months at most. However, over three years later, the land mass, situated between the uninhabited Polynesian islands of Hunga Tonga and Hunga Ha’apai, is showing no signs of dissipating. Now, NASA scientists believe it may be around for as long as 30 years!...

Study Suggests The Human Brain Stops Making New Cells At Age 13

Scientists have always known that a majority of the brain’s neurons, specialized cells responsible for transmitting information throughout the body, are formed at the fetal stage. However, after studies on mammals, like rats, showed that neurogenesis continues in the dentate gyrus, a part of the hippocampus area of the brain vital to memory formation, through adulthood, it was assumed the same was true for humans as well. However, scientists from the University of California, San Francisco are challenging this long-held belief with a new study which asserts the human brain stops adding new neurons by age 13....

This Super-Colony Of Adélie Penguins Has Been Hiding In Plain Sight For Decades

It might sound like 1.5 million penguins are a hard thing to miss. However, that is indeed the case with this super-colony of Adélie penguins ( Pygoscelis Adeliae ) who have managed to remain undetected for decades in the Danger Islands of Antarctica. The remote, difficult to access, landmass, which lies off the continent’s northern tip, is always surrounded by thick ice. It was, therefore, believed to be uninhabitable and largely ignored by scientists....

Adorable Blue-Eyed Robot Teaches Infants To Communicate

Experts believe that the optimal time to teach kids language skills is when they are infants. Most times the task is easily accomplished with parents reading or talking to their babies. However, in some cases that is not possible due to busy work schedules or when kids are born deaf. In the latter case, parents either have to quickly become adept at sign language or risk the child facing potential learning delays in the future. Now, an adorable blue-eyed robot, a human avatar, and some high-tech neuroscience may be able to assist parents and guardians with this crucial developmental task....

Bespectacled Praying Mantises Surprise Researchers With A New Form Of 3D Vision

Stereo, or 3D, vision is what enables humans to gauge the depth and distance of surrounding objects. The right and left eye capture slightly different images and send them to the brain, which merges them and then calculates the proximity of everything in the vicinity. The ability, which requires an intricate network of neurons and lots of processing power, can also be found in a select group of animals like cats, horses, owls and sheep, as well as one insect — the praying mantis....

Groundbreaking Discovery Of Exoplanets Beyond The Milky Way

With over 3,500 exoplanets confirmed as of January 2018 and more being observed on a regular basis, the discoveries have become almost routine. However, all the planets found thus far have been within the Milky Way, the galaxy that contains our solar system. Now, scientists from the University of Oklahoma believe they may have found evidence of trillions of planets beyond our galaxy....

Distant Sun-Like Star May Be Devouring Its Own Planets

RZ Piscium, a star located 550 light years away in the constellation Pisces, has long intrigued researchers with its strange “winking” behavior. During the erratic episodes, which last as long as two days, the celestial body becomes about ten times dimmer and discharges a larger than normal amount of energy at infrared wavelengths, indicating the presence of enormous dust clouds....

Study Reveals Alligators Will Do Anything For A Tasty Morsel — Even Venture Into Salty Waters!

The American alligator (Alligator mississippiensis) is known to be a crafty and fierce predator that devours anything it can snare. However, given that the reptile lacks salt glands, scientists had always believed that its diet was restricted to the fish and crustaceans that dwell in its freshwater habitat. Now, a new study suggests that the opportunistic beasts also gobble down saltwater inhabitants like crabs, sea turtles, stingrays, and even sharks....

On January 31, millions of stargazers around the globe will witness what promises to be a spectacular total lunar eclipse. While the celestial event is always special, what makes Wednesday’s particularly noteworthy is that it coincides with both a blue moon and a supermoon. Hence the moniker “super blue blood moon.” According to NASA, the lunar trifecta is the first of its kind in 35 years and will not occur again until 2037....

MIT Researcher Wants To Light Up The World With Glowing Plants

If Michael Strano has his way, homes and streets of the future will be lit up with “green” energy — literally — from glowing plants and trees. While that may sound like a lofty goal, the Massachusetts Institute of Technology (MIT) professor of chemical engineering and his team are well on their way to realizing the dream with a luminescent plant, which they hope will someday replace your bedside or table lamp!...

Spacesuits Of The Future May Feature "Take Me Home" Buttons To Bring Back Astray Astronauts

Science fiction thrillers frequently feature accidents that cause astronauts to float away into space. Though this has yet to happen in the real world, it is a risk every astronaut is well-aware of when embarking on a spacewalk or Extra Vehicular Activity (EVA). To prevent the nightmare scenario, space explorers are not only tethered to the spacecraft but also fitted with a backup safety kit....

Newly Discovered Largest Prime Number Could Fill Up 9,000 Pages!

On January 4, the Great Internet Mersenne Prime Search (GIMPS), a group of volunteers who use freely available software to search for Mersenne prime numbers, announced the discovery of a new “largest known prime number.” For those that need a refresher a prime number is a positive integer that can only be divided by itself and 1. Since they follow no set pattern, the numbers are hard to discover, which is probably why mathematicians are continually challenging themselves to find the next big one....

Sorry Kids, Asia's Mysterious Abominable Snowmen Are Just Bears!

Tales of the Abominable Snowman, or Yeti, that roams the Himalayas have been a fixture in the Nepalese, Tibetan, and Bhutanese cultures since the 1800s. The belief in the mythical creature spread to the western world in 1951, following British explorer Eric Shipton’s discovery of a massive footprint in the snow while seeking an alternate route to Mt. Everest. Numerous expeditions, many sponsored by large organizations, spent months searching the mountain ranges for the elusive, ape-like creature. Though none succeeded, the belief in yeti’s existence never waned....

Brainless Jellyfish Could Help Reveal Why We Sleep

The reason animals “waste” so much time sleeping has always been somewhat of a mystery to scientists. The popular belief is that resting rids brain cells of toxins, helps consolidate fresh memories and prepares the mind for a new day of learning. However, a new study by a team of research students at the California Institute of Technology has unveiled it’s not just creatures with brains that snooze - even the brainless jellyfish need their zzz’s!...
