Officials with battery maker Form Energy have announced the development of the Iron-Air 100-hour storage battery—a battery meant to store electricity created from renewable sources such as solar and wind. As part of their announcement, they note that their new battery is based on iron, not lithium, and thus is much less expensive to produce.
The team at Form Energy describe their new battery as a multi-day energy storage system—one that can feed electricity to the grid for approximately 100 hours at a cost that is significantly lower than lithium-ion batteries.
The basic idea behind the iron-air battery is that it takes in oxygen and then uses it to convert iron inside the battery to rust, later converting it back to iron again. Converting back and forth between iron and rust allows the energy that is stored in the battery to be stored longer than conventional batteries.
Ever since Star Wars brought podracing and flying motorcycles to the forefront of TV, it’s fair to say most people have wanted to fly one. Luckily, we truly are entering an era of flying vehicles – after all, flying cars will be raced around a track by the end of the year – and flying motorcycles are next on that list.
Jetpack Aviation’s “The Speeder” is the answer to all our sci-fi prayers. A jet turbine-powered motorcycle that looks more like a flying jet ski, this new vehicle prototype has just completed the first test flight that will enable it to go into the next stage of production.
While it isn’t necessarily the completed vehicle that took flight, the company was testing its VTOL self-stabilizing jet platform that will make the basis for their Speeder vehicle. The tests showed it could hover, turn, move in various directions, and right itself after being knocked – all incredibly difficult feats when working with four jet engines.
AI is entering take-off mode just as we exit an economic downturn caused by the pandemic. Get ready for a productivity boom.
Arm thinks those kinds of applications may not be far away, though. In a paper published last week in Nature, researchers from the company detailed a 32-bit microprocessor built directly onto a plastic substrate that promises to be both flexible and dramatically cheaper than today’s chips.
“We envisage that PlasticARM will pioneer the development of low-cost, fully flexible smart integrated systems to enable an ‘internet of everything’ consisting of the integration of more than a trillion inanimate objects over the next decade into the digital world,” they wrote.
Flexible electronics aren’t exactly new, and sensors, batteries, LEDs, antennae, and many other simpler components have all been demonstrated before. But a practical microprocessor that can carry out meaningful computations has been elusive thanks to the large number of transistors required, say the researchers.
The Rijksmuseum employed an AI to repaint lost parts of Rembrandt’s “The Night Watch.” Here’s how they did it.
More TAME! The first part of this has a lot of result data.

“It’s an extraordinary paper with some extraordinary claims,” says Gray Camp, a developmental biologist at the University of Basel in Switzerland, whose lab last year reported2 growing brain organoids that contained a gene common to Neanderthals and humans. The latest work takes the research further by looking at gene variants that humans lost in evolution. But Camp remains sceptical about the implications of the results, and says the work opens more questions that will require investigation.
Humans are more closely related to Neanderthals and Denisovans than to any living primate, and some 40% of the Neanderthal genome can still be found spread throughout living humans. But researchers have limited means to study these ancient species’ brains — soft tissue is not well preserved, and most studies rely on inspecting the size and shape of fossilized skulls. Knowing how the species’ genes differ from humans’ is important because it helps researchers to understand what makes humans unique — especially in our brains.
The researchers, led by Alysson Muotri, a neuroscientist at the University of California, San Diego, used the genome-editing technique CRISPR–Cas9 to introduce the Neanderthal and Denisovan form of a gene called NOVA1 into human pluripotent stem cells, which can develop into any cell type. They cultured these to form organoids, clumps of brain-like tissue, up to 5 millimetres across, alongside normal human brain organoids for comparison.
Skygazers believe they saw a meteor streak across the Texas sky Sunday night.
Update 3:30 p.m. EDT July 26: NASA Meteor Watch confirmed what hundreds of eyewitnesses across the Midwest already knew, that a fireball seen streaking across the night sky was a meteor.
On August 26, 2020, NASA’s Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that had been racing toward Earth for nearly half the present age of the universe. Lasting only about a second, it turned out to be one for the record books – the shortest gamma-ray burst (GRB) caused by the death of a massive star ever seen.
GRBs are the most powerful events in the universe, detectable across billions of light-years. Astronomers classify them as long or short based on whether the event lasts for more or less than two seconds. They observe long bursts in association with the demise of massive stars, while short bursts have been linked to a different scenario.
