It is the highest resolution sensor of its type ever made.

Canon has developed an image sensor that is capable of capturing high-quality color photography even in the dark. The company says that it will be able to shoot clear photos even in situations where nothing is visible to the naked eye.

In a report from Nikkei, Canon says that it has developed a new type of light-receiving element called a single photon avalanche diode (SPAD) and is implementing it on a CMOS sensor. SPAD photodetector technology on its own isn’t new, and has been in use since the 1970s. However, Canon has managed to create a sensor with 3.2 million pixels, which it says is more than three times the resolution of conventional SPADs and makes it the highest-resolution sensor of its type ever made.

The sensor is designed to replace, or at least provide an alternative to, infrared night vision cameras. Infrared is useful for recognizing shapes and providing sight in the dark, but is not capable of recognizing colors. On the flipside, cameras that can see color in the dark only do so by leveraging high ISOs, which can work to a certain point but eventually lead to extremely noisy images in levels of extreme darkness.

Circa 2013 😳!

What would you do with a 600km high structure? That would be hundreds of times higher than the highest ever built so far. I think it is feasible. Here I will suggest super-light, super-strong building materials that can substitute for steel and concrete that can be grown up from the base using feasibly high pressures.

I recently proposed a biomimetic technique for printing graphene filaments to make carbon fur (- in this case, for my fictional carbon-obsessed super-heroine Carbon Girl. I am using the Carbon Trio as a nice fun way to illustrate a lot of genuine carbon-related concepts for both civil and military uses, since they could make a good story at some point. Don’t be put off by the fictional setting, the actual concepts are intended to be entirely feasible. Real science makes a better foundation for good science fiction. Anyway, this is the article on how to make carbon filaments, self-organised into fur, and hence her fur coat:)

Facebook on Thursday announced that it is opening up Horizon Worlds, its virtual reality world of avatars, to anyone 18 and older in the U.S. and Canada.

Horizon Worlds launched in beta last year to select Oculus VR users, who answered invitations to join the virtual world. With the announcement on Thursday, users will no longer need to be invited.

The broader launch of Horizon Worlds is an important step for Facebook, which officially changed its name to Meta in October. The company adopted the new moniker, based on the sci-fi term metaverse, to describe its vision for working and playing in a virtual world.

In a paper published today in the scientific journal Science, DeepMind demonstrates how neural networks can be used to describe electron interactions in chemical systems more accurately than existing methods.

Density Functional Theory, established in the 1960s, describes the mapping between electron density and interaction energy. For more than 50 years, the exact nature of mapping between and interaction energy—the so-called density functional—has remained unknown. In a significant advancement for the field, DeepMind has shown that can be used to build a more accurate map of the and interaction between electrons than was previously attainable.

By expressing the functional as a neural network and incorporating exact properties into the , DeepMind was able to train the model to learn functionals free from two important systematic errors—the delocalisation error and spin symmetry breaking—resulting in a better description of a broad class of chemical reactions.

Nowadays almost everything is being 3D printed, so why should architecture be an exception? Many architectural firms are adopting 3D printing as their preferred technique to build structures. And 3D printed architecture is slowly but surely gaining a lot of popularity and momentum. This emerging trend is paving a path for itself in modern architecture. And I mean, no wonder, it has a ton of benefits! It’s a simple, efficient, and innovative technique that lowers the risks of errors, and also manages to save on time. 3D printing eradicates a lot of tedious steps during the construction process and simplifies it. It is being used to build homes, habitats on Mars, and even floating islands! The potential and possibilities of 3D printing in architecture are endless and mind-blowing. We’ve curated a collection of 3D-printed architectural structures that are our absolute favorites – from a 3D printed sustainable office pod to a 3D printed housing community for the homeless, every single one of these designs unleashes the magic and potential of 3D printing!

Moving CO2 from Air to Oceans May Be Necessary to Slow Warming.

Climbing concentrations of carbon dioxide make it likely that humans will have to move some gases from the atmosphere into the oceans to prevent crippling effects of climate change, the National Academies said in a major report released yesterday.

It came after months of deliberation among top U.S. scientists who concluded that global efforts to reduce emissions, even if successful, “may not be enough to stabilize the climate.” The report identified six ways to capture and store carbon dioxide in the oceans, a controversial idea that the report said “will likely be needed.”

Potential methods include stimulating more plant growth in and around the oceans and manipulating ocean currents to draw CO2 deep underwater.
