Sodium-ion batteries vs. lithium-ion batteries: What are the advantages of sodium-ion batteries for EVs?
Most of the rechargeable batteries used in today’s technology, from electric cars to pocket phones, are lithium-ion (Li-ion) batteries. Since its inception in the early 1990s, lithium-ion battery technology has been widely adopted due to its high energy density, lightweight construction, and ability to provide high voltage on demand to equipment, vehicles, and more. But […]
Chinese EV maker claims to have developed world’s first semi-solid EV battery with 620 miles of range
Chinese researchers have tested a next-generation solid-state battery that could extend the range of electric cars far beyond current limits. It could travel more than 620 miles (1,000 kilometers) on a single charge, and future versions could go even further. Scientists at Tianjin’s Nankai University have developed a high-energy solid-state battery system that has already […]
Research on “oracle bones” reveals a climate disaster that caused social chaos in China 3,000 years ago
A sharp population decline during the decline of China’s Shang dynasty more than 3,000 years ago was likely the result of an increase in deadly typhoons and related weather events, a new study combining ancient documents, archaeological evidence and paleoclimate modeling finds. It is highly likely that these coastal typhoons caused catastrophic weather phenomena such […]
Can you tie a knot in four dimensions? A mathematician explains.
We all know that we live in three-dimensional space. But what do people mean when they talk about the fourth dimension? Is it just a large space? Is it the general idea of “spacetime” born from Einstein’s theory of relativity? If you’ve ever wondered what the fourth dimension actually looks like, you may have seen […]
‘Truly extraordinary’: Megalaser beaming at us from the far side of space is the brightest ‘cosmic light’ we’ve ever seen
Astronomers have discovered a supercharged space laser beaming toward Earth from the far side of the universe. A beam of cosmic energy revealed in part by a strange space-time trick first predicted by Einstein is the brightest and most distant beam of its kind ever observed. A natural laser called a “hydroxyl megamaser” is essentially […]
Killer whale fin chewed up on Russian coast points to possible cannibalism, scientists say, could explain why some pods are so tightly bound together
The fins of killer whales found washed up in the North Pacific Ocean have distinctive tooth markings, suggesting that killer whales occasionally engage in cannibalism. Scientists say this may explain why some killer whales live in large family groups. There are several different species of killer whales (Orcinus orca), which are sometimes considered separate subspecies. […]
NASA fixes Artemis II rocket that will carry astronauts around the moon for April launch
NASA has announced that it has resolved the helium issue on its Artemis II rocket, which is scheduled to launch to the moon in the coming weeks. Artemis II will carry four astronauts and fly around the moon on a historic journey that will take humanity further into space than ever before. But last month, […]
New study finds bird declines accelerating in three US hotspots
Bird populations are in free fall across North America. And in some hotspots, the decline is accelerating, a new study finds. From 1987 to 2021, bird populations in California, the Midwest, and the Mid-Atlantic region declined at an accelerating rate. Across these hotspots, bird declines were associated with high-intensity agriculture, according to the study. The […]
Introducing the world’s smallest AI supercomputer. It packs “doctor-level intelligence” and is small enough to fit in your pocket, according to its developers.
A US startup has developed what it claims is the world’s smallest artificial intelligence (AI) supercomputer. It’s packed with high-performance hardware and plenty of RAM, and is compact enough to fit in your pocket, yet can run “Ph.D. intelligence” AI models, company representatives say. This means being capable of autonomous problem solving, abstract reasoning, and […]
When was the last time there was no ice in Antarctica?
Almost four times the size of the United States, Antarctica is almost completely covered in a layer of ice several miles thick. But Antarctica isn’t always frozen. So when was the last time there was no ice in Antarctica? Experts told Live Science that this ice sheet formed relatively recently geologically. “Most people would say […]
