One critical part of the Koenigsegg Gemera’s brain-scrambling powertrain is its ‘Freevalve’ petrol engine. You might have glossed over it while trying to compute the outputs, and they way that engine combines with three electric motors to produce, er, 1700bhp in all. Or in metric, 1.27 Megawatts. Or the power draw of a couple of hundred houses cooking dinner.

Christian von Koenigsegg, though, will talk for hours about this engine. He’s so affectionate about the thing he’s got a nickname rather than the usual dreary car-business habit of codenames. This, then, is the Tiny Friendly Giant.

Giant because 600bhp. Tiny because it’s just two litres and three cylinders. Maybe two litres isn’t that tiny in displacement (though CvK’s cars have mostly had big V8s) but it’s physically very small and easy to package. It has just the three cylinders, and no overhead camshaft casings, and no camshaft drive on the front.

Scientists have been using a new form of gene therapy to treat a rare inherited eye condition which eventually causes severe tunnel vision.

Scientists have been using the new treatment on patients to try to halt further loss of sight. And they’ve been astonished to find that it has actually improved their vision.

A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) have developed a system with which they can fabricate miniature robots building block by building block, which function exactly as required.

As one would do with a Lego system, the scientists can randomly combine individual components. The blocks or voxels—which could be described as 3D pixels—are made of different materials: from basic matrix materials that hold up the construction to magnetic components enabling the control of the soft machine. “You can put the individual soft parts together in any way you wish, with no limitations on what you can achieve. In this way, each has an individual magnetisation profile,” says Jiachen Zhang. Together with Ziyu Ren and Wenqi Hu he is first author of the paper entitled “Voxelated three-dimensional miniature magnetic soft machines via multimaterial heterogeneous assembly.” The paper was published in Science Robotics on April 28, 2021.

The project is the result of many previous projects conducted in the Physical Intelligence Department at MPI-IS. For many years, scientists there have been working on magnetically controlled robots for wireless medical device applications at the small scale, from millimeters down to micrometers size. While the state-of-the-art designs they have developed to date have attracted attention around the world, they were limited by the single material with which they were made, which constrained their functionality.

On Thursday, China launched the core module of its planned space station to pave the way for construction to begin.

Designed to rival the International Space Station (ISS), from which Chinese astronauts have been barred, the assembly of the facility is expected to be completed by the end of next year.


The geopolitical tensions playing out on Earth are now out of this world as nations build alliances to boldly go where no man has gone before.

The subseafloor constitutes one of the largest and most understudied ecosystems on Earth. While it is known that life survives deep down in the fluids, rocks, and sediments that make up the seafloor, scientists know very little about the conditions and energy needed to sustain that life.

An interdisciplinary research team, led from ASU and the Woods Hole Oceanographic Institution (WHOI), sought to learn more about this ecosystem and the microbes that exist in the subseafloor. The results of their findings were recently published in Science Advances, with ASU School of Earth and Space Exploration assistant professor and geobiologist Elizabeth Trembath-Reichert as lead author.

To study this type of remote ecosystem, and the microbes that inhabit it, the team chose a location called North Pond on the western flank of the mid-Atlantic Ridge, a plate boundary located along the floor of the Atlantic Ocean.

Let the farming games begin.


Chinese motherboard manufacturer Onda (via ZOL) has launched the brand’s new Chia-D32H-D4 motherboard. The model name alone is enough to tell you that this motherboard is aimed at farming Chia cryptocurrency, which has already caused hard drive price spikes in Asia.

Designed for mining, rather than to compete with the best motherboards for gaming, the Chia-D32H-D4 is most likely a rebranded version of Onda’s existing B365 D32-D4 motherboard. It measures 530 × 310mm, so the Chia-D32H-D4 isn’t your typical motherboard. In fact, Onda has produced a special case with an included power supply for this specific model. The unspecified 800W power supply arrives with the 80Plus Gold certification, while the case features five cooling fans.
