What is NATO and when does it act?

NATO — the North Atlantic Treaty Organization, to give it its full name — is a non-aggressive European and North American defense alliance set up to promote peace and stability and to safeguard the security of its members. The organization, which has its headquarters in Brussels, Belgium, was created as the Cold War escalated. Its…

Unknown space object beaming out radio signals every 18 minutes remains a mystery

While mapping radio waves across the universe, astronomers happened upon a celestial object releasing giant bursts of energy — and it’s unlike anything they’ve ever seen before. The spinning space object, spotted in March 2018, beamed out radiation three times per hour. In those moments, it became the brightest source of radio waves in our…

Frogs can regrow amputated limbs after being treated with mix of drugs, new research finds

Some unusual creatures have an innate ability to regrow a limb: salamanders, starfish, crabs, lizards and newts. Such extraordinary powers elude most animals, including humans, although scientists have long sought to understand and replicate them in a quest to regenerate limbs for millions of patient amputees, including diabetics and victims of trauma. Now, researchers in…

Over 10 years and $1bn on the table yet little was achieved in a historic forests deal, study says

More than a decade ago, Indonesia and Norway made a landmark deal: Norway would pay Indonesia up to $1 billion to slash its planet-warming emissions by slowing deforestation. The pact had some success, but new research shows it contributed little to Indonesia’s climate goals and suggests Norway could have paid the country far more for…

Skin whitening: What is it, what are the risks and who profits?

Skin whitening is the use of cosmetic products or services to reduce the amount of melanin, or pigment, in the skin to make it appear lighter. It’s a big industry and predominantly targets women of color in every region of the world, with the Asia-Pacific region being the most lucrative. The practice dates back centuries,…

Saturn’s ice moon could be a ‘stealth’ ocean world hospitable to life

Saturn’s innermost moon, which resembles the Death Star from Star Wars, may be a “stealth” ocean world, according to new research. Mimas, which is the smallest and closest to Saturn of the ringed planet’s 82 moons, may contain a liquid internal ocean. “If Mimas has an ocean, it represents a new class of small, ‘stealth’…

Stunning find discovered hiding in the ocean’s ‘twilight zone’

Stunning find discovered hiding in the ocean’s ‘twilight zone’

The ocean depths are as mysterious as the infinite abyss of space beyond our planet. Every time we dive beneath the waves, or those waves surface an unusual creature, we learn something new about the water covering more than 70% of Earth’s surface. Only around 20% of the ocean floor has been mapped, according to…

Debris from Russian missile test nearly strikes a Chinese satellite

A piece of debris created by Russia’s recent anti-satellite test came within striking distance of a Chinese satellite Tuesday, in an encounter the Chinese government has called “extremely dangerous.” The Russian debris came as close as 14.5 meters (approximately 48 feet) from the satellite, according to the Space Debris Monitoring and Application Center of the…

A black hole fueling star birth has scientists doing a double-take

Black holes are best known for shredding stars, devouring light and acting like massive garbage disposals in space. In a twist, astronomers using the Hubble Space Telescope have discovered that these energetic celestial objects have a nurturing side, too. Hubble’s observation of a dwarf starburst galaxy, called Henize 2-10, revealed a gaseous umbilical cord stretching…

The Doomsday Clock reveals how close we are to…doom

The Doomsday Clock has been ticking for exactly 75 years. But it’s no ordinary clock. It attempts to gauge how close humanity is to destroying the world. On Thursday, the clock was set at 100 seconds until midnight — the same time it has been since 2020. The clock isn’t designed to definitively measure existential…

‘Living fortress’ dinosaur was lonesome, sluggish and hard of hearing

Life as a “living fortress” was a lonesome one for this dinosaur. A heavily armored nodosaurid, which sported elongated spikes on its neck and shoulders, was likely a sluggish loner who couldn’t hear very well, according to a new study. Researchers studied the braincase of the 80 million-year-old herbivorous dinosaur, which was related to the…

Scientists made an incredible discovery in the ocean’s ‘twilight zone’ off Tahiti

Deep in the ocean off the coast of Tahiti, scientists made an incredible discovery in November: acres of giant, pristine, rose-shaped corals blossoming from the sea floor in what’s known as the ocean’s “twilight zone.” That a coral reef so large and so beautiful had yet to be discovered emphasizes how little we still know…

A Canadian restaurant had to close its dining room because it accepted dog photos in lieu of proof of vaccination, negative Covid tests

A restaurant in Alberta was forced to briefly close its dining room after the health department found patrons were showing photos of dogs instead of proof of vaccination or a negative Covid test, as mandated by the Canadian province. Alberta Health Services ordered The Granary Kitchen in Red Deer to temporarily close last Friday after…

King Tut’s tomb had a scepter. This ancient burial had something entirely different

This may be the world’s oldest surviving evidence of supersize thirst quenchers. Mysterious scepters found in an ancient burial mound could actually be giant drinking straws — and they were used to consume mass quantities of beer. The gold and silver straws, each measuring about 3.6 feet (1.1 meters) long, are over 5,000 years old.…

A huge, kilometer-wide asteroid will pass by Earth today

An asteroid estimated to be around a kilometer (3,451 feet) wide will fly by Earth on Tuesday. It will pass within 1.2 million miles of our planet, moving at 47,344 miles per hour (76,193 kilometers per hour), according to NASA’s Center for Near Earth Object Studies, which tracks potentially hazardous comets and asteroids that could…

Tonga volcano eruption likely not large enough to affect global climate, experts say

Though massive volcanoes have the potential to affect global temperatures and weather, the eruption near Tonga on Saturday was likely not large enough to impact global climate, experts tell CNN. The Hunga-Tonga-Hunga-Ha’apai eruption on Saturday was enormous; likely the largest in 30 years, according to experts. It injected a huge cloud of ash and sulfur…
