Fujitsu and the Riken research institute ended up packing 152,064 A64FX chips into what would become the Fugaku system, which is now the world’s fastest supercomputer.
Gallium arsenide (GaAs) has long been touted as the best material for making high-efficiency solar cells because of its extraordinary light absorption and electrical characteristics. It has most notably been put to use in space solar panels.
These GaAs solar cells, however, are extremely pricey to produce resulting in a demand for methods that cut down on the material usage. That’s where nanowire structures come in. These elements can potentially enhance solar cell efficiency compared to standard planar solar cells while utilizing less material.
By using GaAs in the nanowire structures, the team of researchers has found a new way to make an ultrahigh power-per-weight ratio solar cell that is more than 10 times more efficient than any other solar cell.

Penn State researchers develop first-of-its-kind wearable, noninvasive glucose monitoring device prototype.
Noninvasive glucose monitoring devices are not currently commercially available in the United States, so people with diabetes must collect blood samples or use sensors embedded under the skin to measure their blood sugar levels. Now, with a new wearable device created by Penn State researchers, less intrusive glucose monitoring could become the norm.
The LAVO bike from StudioMOM is the world’s first hydrogen bike, requiring no heavy batteries, particulates, or CO2 emissions for operation.
Nowadays, it seems bikes are the preferred mode of transportation in crowded cities. Traffic is no joke and public transportation has seen some major changes since the onset of the COVID-19 pandemic, so people are hitting the streets with shiny electric and portable bicycles. While bikes are generally more environmentally friendly than cars and trucks, they come with their own list of setbacks. Becoming the world’s first hydrogen bike, the LAVO bike from StudioMOM is a small solution to a big problem.
The contraption can charge the car in 40 hours. 🚗
The heavy trailer is bound to reduce the car’s range.
A constitution for Mars’ future government is further along than you think.
A constitution for a colonized Mars’ future government is further along than you think. Former SpaceX general counsel, David Anderman, tells us how it could work.

Dubbed 4660 Nereus, or 1982 DB, this vaguely egg-shaped asteroid has a size making it taller than the Eiffel Tower and nearly twice as tall as the Washington Monument. It is set to pass by the planet on December 11 at a distance of approximately 3.9 million kilometers and at a speed of 6.578 km/s.
For comparison, the distance between the Earth and the Moon is about a thousandth of that – around 385,000 km. As such, despite being classified as a Potentially Hazardous Asteroid (PHA) due to its size and close proximity to Earth, it seems unlikely to pose a threat to the planet.

NASA is getting ready to launch a spacecraft to test an experimental method to deflect near-Earth objects, and you can participate in the mission by testing your own planetary defense know-how.
The space agency’s Double Asteroid Redirection Test (DART) mission is designed to test a “kinetic impactor” technique for deflecting any asteroid or comet that might otherwise impact Earth.
“It doesn’t sound like a lot when you look at the numbers, but those are completely preventable deaths,” Zane Zents, the lead software engineer for the Grain Weevil robot, told NTV News. “It’s something that in the 21st century I don’t think we should still be dealing with.”
The Grain Weevil: Zents’ fellow student Ben Johnson was studying electrical engineering at UNO when he received a special request from a farmer friend, Zach Hunnicutt.
“(He) said, ‘Hey, look, you guys build robots. Why don’t you build me a robot so I and my children never have to go into a grain bin again?’” Johnson told AgWeb in May.
