If the recently released Jurassic World: Fallen Kingdom has you yearning to see the ancient creatures in real life, you are out of luck. That’s because to resurrect the animals, researchers would need a complete set of dinosaur DNA, which is impossible to obtain. However, if Nikita and Sergey Zimov have their way, a prehistoric Ice Age ecosystem may soon become a reality. Their motive is not to attract tourists but to stop the thawing of the Arctic permafrost....

Most animals only perform tricks when bribed with treats. However, Kim, the world’s first spider to learn a skill, needs no incentives to do what she loves — jumping from different heights and distances — upon the bidding of a team of scientists from the University of Manchester....

Pesky as they may be, ants are truly incredible creatures. In addition to talents like predicting earthquakes and morphing into rafts to save themselves from drowning during floods, the industrious insects go all out to protect their own, often carrying wounded comrades back to the nest to heal. Now, researchers have discovered ants who explode and sacrifice themselves to save their colonies from predators....

After successfully banning plastic bags, officials around the world are turning their attention to something we are all guilty of using for only a few minutes and disposing of without a second thought – plastic straws. According to ecostraw.org, over 500 million straws, enough to fill 127 school buses, are used just in the US, each day! Too small to recycle, they choke sea creatures, clog coral reefs, and eventually disintegrate into tiny microbeads which enter our food chain through fish. This means that every single straw ever produced in the world still exists in some form today. Now, thanks to social media campaigns such as #TheLastStraw and #TheFinal Straw, the urgency to ban plastic straws is finally gained momentum....

One would think that an elephant bird egg, the largest laid by any vertebrate ever — including dinosaurs and ancient reptiles — would be hard to miss for 80 years. Yet, that is precisely what Paige Langle at New York’s Buffalo Museum of Science discovered recently while inputting the institution’s extensive collections, many of which only exist on cards and ledgers, into the museum’s computer system....

Though it is not uncommon for the Kilauea volcano on the southern shore of Hawaii’s Big Island to erupt, the recent explosion is the worst encountered in decades. The sea of lava, which has been flowing unabated since May 3, has encompassed 104 acres (the equivalent of 100 football fields), destroyed 35 structures — including 26 homes — and forced almost 2,000 people to evacuate. Unfortunately, even experts have no idea when the volcanic activity will subside....

In mid-March, following an extended period of heavy rainfall, residents of the Mai Mahiu settlement in Kenya woke up to a big surprise – a massive crack in the Earth that appeared to have opened up almost overnight. Running several miles long and measuring 50 feet deep and 65 feet wide in some places, the terrifying fissure damaged several homes and caused a portion of the busy Mai Mahiu Narok-Nairobi highway to collapse. What caused it? Depends on who you ask....

A parasite that can transform ants into zombies and make them do its bidding may sound like something straight out of a science fiction movie. However, that is precisely what the Ophiocordyceps unilateralis, or, zombie ant fungus does to unsuspecting carpenter ants. Now, a new study has discovered that the fungus accomplishes this ghoulish feat without infecting the ant’s brain....

Last week, a runner traversing the trails of California’s Pinnacle National Park, encountered a mesmerizing sight — a halo of rainbow colors emanating from the single cloud in the clear blue skies. While the phenomenon is commonly referred to as a “fire rainbow,” researchers say the name is misleading since the optical illusion is neither a rainbow, nor does it have anything to do with fire!...

While birds may appear to flutter about in the world, magically finding their way to food and other members of the flock, the reality is, species migrate to the same destination, time and again. Over the years, researchers have established that the animals use Earth’s magnetic fields as guides. However, how they sense these fields has been a mystery....

The Earth Day Network may have an unexpected ally in its quest to solve the global plastic pollution crisis: bacteria. More specifically, an enzyme produced by the Ideonella sakaiensis microbes. Dubbed PETase, it can expertly break down PET (polyethylene terephthalate), one of the most common types of plastic, within days, instead of the over 450 years it takes the synthetic material to decompose naturally....

Over the years, Germany’s Festo has engineered some incredibly cool and functional bio-inspired robots, including ones that mimic ants, butterflies, flying jellyfish, and seagulls. On March 27, the electrical automation company added to the impressive list with two new creations — a realistic flying fox bat and a somersaulting robotic spider....

On Sunday, April 22, more than a billion people around the world will celebrate Earth Day by participating in neighborhood clean-up efforts. The grassroots movement began in 1970 when twenty million Americans took to the streets to voice their concern about the deteriorating environment and to urge lawmakers to take action before it was too late. Now boasting over 50,000 partners in 195 countries, the Earth Day Network (EDN) is credited with instigating many of our current environmental policies, including the Clean Air Act, Clean Water Act, and Endangered Species Act....

Every year from March to October, Christian Moullec, aka “Birdman,” takes to the skies aboard his two-seater adapted light aircraft, derived from hang-gliders. However, the 58-year-old Frenchman’s daily 30-minute flight is not just to enjoy the spectacular views, but to guide flocks of lesser white-fronted geese through safe migration paths which the birds can teach future generations....

With memories of Hurricanes Harvey, Irma, and Maria, which ravaged Texas, Florida, and Puerto Rico in 2017, still fresh in their minds, residents of the US Atlantic and Gulf Coast are bracing for yet another busy hurricane season. Researchers at Colorado State University predict a slightly above-average 2018 season with 14 tropical storms, at least three of which are expected to be major hurricanes, Category 3 or higher! Though having the advance warning is helpful, it would be even better if we could find a way to stop the deadly storms from forming altogether. Now, Norwegian researchers may have found the answer in — of all places — air bubbles....

Don’t be alarmed if your city, town, or neighborhood goes dark from 8:30 - 9:30 PM local time tonight (March 24). The blackout is not due to a sudden electricity outage, but a voluntary gesture to celebrate Earth Hour, which will be observed worldwide and include iconic landmarks like the Eiffel Tower, the Empire State Building, and the Sydney Opera House. The simple action, designed to demonstrate what can be achieved if we all unite to help reverse climate change, is the brainchild of the Australian chapter of the World Wildlife Fund (WWF)....

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....

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....

Though animals are continually evolving to adapt to their environment, it is hard to observe the process real time in the wild. Now, some international scientists have stumbled upon a unique group of West African dwarf crocodiles that may be in the midst of mutating into a new species....

A 14-year-old with a vocabulary comprising four or five rudimentary words may not sound impressive. However, it sure is when the speaker happens to be an orca, or killer, whale! The amazing discovery along with the recording of the vocalization was unveiled in a January 31 study published in the journal Proceedings of the Royal Society B....

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....

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....

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!...
