Thawing Arctic permafrost laden with billions of tonnes of greenhouse gases not only threatens the region’s critical infrastructure but life across the planet, according to a comprehensive scientific review. Nearly 70 percent of the roads, pipelines, cities, and industry – mostly in Russia – built on the region’s softening ground are highly vulnerable to
Ocean temperatures the world over are building at a relentless rate as humans continue to alter the atmosphere around them. In 2021, according to a new summary of two international datasets, the wave of warmth in our oceans hit a new peak, eclipsing the influence of cooler regional episodes. While last year’s ocean warming
Scientists have built the tiniest antenna ever made – just five nanometers in length. Unlike its much larger counterparts we’re all familiar with, this minuscule thing isn’t made to transmit radio waves, but to glean the secrets of ever-changing proteins. The nanoantenna is made from DNA, the molecules carrying genetic instructions that are around
Innovators at South Korea’s Ajou University have created a robotic hand that is capable of holding fragile objects like eggs. It can also crush cans and work with tools like tweezers and scissors. An article published in Nature Communications explained all the details of the new technology. It weighs just under two and a half pounds
Scientists have observed a stunning demonstration of classic physics giving way to quantum behavior, manipulating a fluid of ultra-cold sodium atoms into a distinct tornado-like formation. Particles behave differently on the quantum level, in part because at this point their interactions with each other hold more power over them than the energy from their movement.
Just seven months after it announced a milestone record for plasma fusion, the Chinese Academy of Sciences has absolutely smashed it. Their ‘artificial Sun’ tokomak reactor is has maintained a roiling loop of plasma superheated to 120 million degrees Celsius (216 million degrees Fahrenheit) for a gobsmacking 1,056 seconds, the Institute of Plasma Physics reports.
“The last star will slowly cool and fade away. With its passing, the Universe will become once more a void, without light or life or meaning.” So warned the physicist Brian Cox in the recent BBC series Universe. The fading of that last star will only be the beginning of an infinitely long, dark epoch.
Extreme weather in Alaska that has brought record high temperatures and torrential downpours has left authorities in the far northern US state warning of “Icemageddon”. Huge sheets of ice are blocking roads and choking traffic in Fairbanks, Alaska’s second largest city, reported the state’s transportation department, which has coined the neologism – a play on
The massive Thwaites glacier in West Antarctica contains enough ice to raise global sea levels by 65cm if it were to completely collapse. And, worryingly, recent research suggests that its long-term stability is doubtful as the glacier hemorrhages more and more ice. Adding 65cm to global sea levels would be coastline-changing amounts. For context,
