This February, mother nature is keeping us occupied with a puzzling new riddle, and the solution has even got the scientists stumped: how exactly did a humpback whale end up dead on the edge of the Amazon rainforest in Brazil? It’s a curiosity that has drawn worldwide attention. The 8-metre-long carcass (26 feet) was found
It was the most explosive scientific controversy of 2018: Chinese scientist He Jiankui brazenly announced in November he had created the world’s first gene-edited babies using CRISPR. He’s admission – including that twin girls called Lulu and Nana from his experiment had already been born – provoked immediate international uproar in the scientific community, with critics
Over four billion years ago, when Earth was turbulent and new, a strange spark of life grew into existence. We’re not entirely sure how it happened, but evidence suggests it was deep under the sea, far below the reach of the Sun’s rays. If we can figure out how that spark formed, it could help
Stratocumulus clouds are rather boring. They’re not as elegant as cirrus clouds (those horsetail wisps high in the sky) or as majestic as cumulonimbus clouds (big, scary thunderheads). But stratocumulus clouds, which hover low in the sky and create vast decks of cloud cover, have a supreme value in our warming world: Their white tops
A man died after crashing a 2016 Tesla Model S into a tree in Miami, Florida yesterday afternoon, according to local news. The car reportedly swerved through multiple lanes of traffic before hitting a median and some trees and bursting into flames – and the death may have been related to the electric carmaker’s iconic
One of the consequences of creating a Space Force is the breakup of Air Force Space Command. The procurement of commercial satellite communications services that is now under AFSC would be reassigned to the Secretary of the Air Force. WASHINGTON — The Air Force Space Command in December assumed responsibility for the procurement of commercial
Have you ever wondered how fish manage to survive temperatures below freezing in Antarctic waters? (You are now.) It’s a pretty neat question – and now, thanks to genome analysis, we actually have an answer. For one fish, that is. And boy is it an odd one. It’s called the Antarctic blackfin icefish (Chaenocephalus aceratus),
At a staggering distance from the Sun, astronomers have just found what they think might be the most distant object ever identified in the Solar System. They’ve yet to characterise or define it, but it orbits the Sun at a massive distance of 140 astronomical units (AU), which puts it 3.5 times farther out than
WASHINGTON — As an Israeli-built lunar lander makes its first post-launch maneuvers, a Japanese company announced new partnerships in its plans to mount missions to the moon. SpaceIL announced Feb. 24 that its Beresheet lander performed its first maneuver since being placed into a supersynchronous transfer orbit by a Falcon 9 Feb. 21. The 30-second
We already know that cats can be as neurotic as their owners are, but just how deep are the personality ties between felines and the humans who serve look after them? Pretty deep, according to new research from scientists in the UK, who found that personality traits of cat owners correlated with related behaviours exhibited
Never before in American history had so many people received a text message at the exact same time. It was bearing grave, unthinkable, catastrophic news – and it wasn’t even true. A little over a year ago, this is what more than a million people in Hawaii saw on their phones, television screens, and flashing
Billions of years ago, Mars was likely a much warmer and wetter place than the cold, dry, barren world we see today. Whether there was life there or not remains an open question. But there’s a massive, growing wall of evidence showing that Mars may have had the necessary conditions for life in the past,

NASA’s Curiosity Mars rover, which touched down in 2014, experienced a “hiccup” while booting up last week – but scientists on Earth have brought it back online and are working to reconstruct what went wrong. “We’re still not sure of its exact cause and are gathering the relevant data for analysis,” said Steven Lee, Curiosity’s
Social media sites like YouTube are stepping up their enforcement against anti-vax content. YouTube channels that promote anti-vaccination content are not allowed to run ads on the video sharing platform, according to a policy first reported by BuzzFeed News on Friday. YouTube said that it considers anti-vaccination content to be “dangerous or harmful,” which as
In a memo to Acting Defense Secretary Patrick Shanahan, Undersecretary of Defense for Research and Engineering Mike Griffin designated Kennedy as his choice to become the first director of the Space Development Agency. WASHINGTON — Fred Kennedy, head of the Defense Advanced Research Projects Agency’s Tactical Technology Office, has been selected to serve as the
For centuries, the pyramids of Giza have puzzled researchers – not just their mysterious voids and hidden chambers, but exactly how ancient Egyptians built such impressive structures without modern technology. One of the most confounding issues is how the structures became so perfectly aligned. Although it’s slightly lopsided, overall the square sides of the 138.8 metre (455

Humanity has always had an uneasy relationship with wolves. They loom large in our ancient mythologies as fearsome beasts; over the millennia, that fear has led to devastation of wolf populations across Europe, including 19th century Germany. In the 1960s, numbers of wolves (Canis lupus) in Europe hit an all-time low, veering perilously close to
There’s been a recent increase globally in outbreaks of vaccine-preventable diseases. This can be seen in recent measles outbreaks in parts of the world where it was thought to have been eradicated. This has prompted the World Health Organisation to list “vaccine hesitancy” (the reluctance or refusal to vaccinate despite the availability of vaccines) as

Now imagine that this armor is not only strong, but also soft and stretchy, so much so that the wearer is able to move their body
When you beam intense pulses of light into a thin circle, strange things will happen, according to new research based on the optical equivalent of a whispering gallery. Inside tiny loops of transparent fibre, waves of light can be forced to break step and change the orientation of their wiggle in odd ways, bending the

Thousands of years ago, an ancient hominin strode through a sand dune, leaving footprints behind. Most of these marks were lost to the ravages of the years, but one was preserved as the sand hardened to stone. That print, scientists have now determined, may have been made by a Neanderthal on the island of Gibraltar.
Scientists may have just taken a step towards experimentally proving the existence of Hawking radiation. Using an optical fibre analogue of an event horizon – a lab-created model of black hole physics – researchers from Weizmann Institute of Science in Rehovot, Israel report that they have created stimulated Hawking radiation. Under general relativity, a black
On the Draupner oil platform off the coast of Norway, workers would expect big waves to shake things up from time to time. But at 3 pm on New Year’s Day in 1995, a monster struck. It made history. Topping out at nearly 26 metres (about 84 feet), it was the kind of wave you might
We know that many of the traits we see in animals are there because they evolved by somehow being useful to the species. But evolution is messy, and the supposed benefits of weird features aren’t always obvious. Take zebra stripes, for example. The stark black and white garb of the three zebra species roaming Africa
3D printers work by laboriously printing objects layer by layer. For larger objects, that process can take hours or even days. But now scientists at the University of California, Berkeley have found a shortcut: a printer that can fabricate objects in one shot using light – and which could, potentially, revolutionize rapid manufacturing technology. The

Football fans in the US can be divided into three camps – those who think the Patriots victory against the Colts in the 2014/15 playoffs were given a helping hand by slightly under inflated footballs, those who don’t, and those who ask ‘OMG can’t we just get on with football?!’ Over the past few years,
Looking at a picture of Wallace’s giant bee, you wouldn’t pick this insect as elusive. Four times as big as a honeybee, and a stark black colour, it looks like the security guard or bouncer of the bee world. But researchers have just released the first photos and video of a live Wallace’s giant bee
The Pinna-Brelstaff illusion is tremendous fun: concentric rings of shapes, with inverse shading. When you move your head closer to or farther from the illusion, the rings appear to rotate, expand, and contract (go ahead, we’ll wait while you try this with the picture above). We know the shading effect plays a role in tricking our brains
Alarming video captured by a Twitter user in Philadelphia highlights a rare but little-known danger of electroshock Taser-style weapons.

Soft, squishy, ancient spiders are hard to investigate – they don’t fossilise as easily as bones or exoskeletons. So you can imagine how excited researchers were to find 10 brand new spider fossils in a relatively unexplored area called the Jinju Formation. The Jinju Formation is a geological area of South Korea from the Mesozoic era,
