Threat analysts have spotted a new Ducktail campaign using a new infostealer variant and novel TTPs (tactics, techniques, and procedures), while the Facebook users it targets are no longer limited to holders of business accounts.

The Moon rotates around the Earth at about the same speed, as it does around its axis, that’s why we can only see one side of it. It means that 41% of its surface hasn’t been explored yet! This fact surprises many people, as we are used to thinking that we know everything about all things in the world. While even our own planet remains a mystery to us.

An international research team led by the Department of Microstructured Quantum Matter at the MPSD reports the first observation of switchable chiral transport in a structurally achiral crystal, the Kagome superconductor CsV₃Sb₅. Their work has been published in Nature.

Whether or not an object is indistinguishable from its mirror image has important consequences for its physical behavior. Say you watch a basketball player in a mirror. The ball, the player and their surroundings are, at first glance, just the same in the mirror as in real life. But if observed closely, some details are different. The ball in the player’s right hand now appears in their left hand in the mirror. While the mirror image still shows the same hand, it has clearly changed from a left to a right hand or vice versa. Many other physical objects also have mirror images that differ in a key aspect, just like hands, which is why scientists call them handed or chiral (from Greek χϵρι = hand). Others, like the ball, cannot be distinguished from their mirror image, which makes them achiral.

Chirality is one of the most fundamental geometric properties and plays a special role in biology, chemistry and physics. It can cause surprising effects: One version of the carvone molecule, for example, produces a spearmint smell but its chiral—mirrored—equivalent smells of caraway.

How will we interact with computers in a few years? Probably very differently than we do today. One developer gives a taste by linking three AI systems for a digital design assistant.

For his AI-based design assistant, Twitter user Progen links three AI systems: the open-source image AI Stable Diffusion for image generation, OpenAI’s Whisper, also open source, for translating spoken words into English, and GPT-3 for dialogs with the assistant.

A London-based artist named Matt DesLauriers has developed a tool to generate color palettes from any text prompt, allowing someone to type in “beautiful sunset” and get a series of colors that matches a typical sunset scene, for example. Or you could get more abstract, finding colors that match “a sad and rainy Tuesday.”

DesLauriers has posted his code on GitHub; it requires a local Stable Diffusion installation and Node. JS. It’s a rough prototype at the moment that requires some technical skill to set up, but it’s also a noteworthy example of the unexpected graphical innovations that can come from open source releases of powerful image synthesis models. Stable Diffusion, which went open source on August 22, generates images from a neural network that has been trained on tens of millions of images pulled from the Internet.

That isn’t to say we’ve yet reached a decentralized utopia. Though decentralized systems are also ostensibly “trustless” systems, it is ironically trust that still must be built up in these systems for both developers and users. Whatever the disadvantages of relying on companies like Amazon, Google, Microsoft and Apple, they have banked decades’ worth of that trust, credibility and familiarity that makes it difficult for both developers and users to switch to an entirely new way of doing things.

Self-organizing lumps of human brain tissue grown in the laboratory have been successfully transplanted into the nervous systems of newborn rats in a step towards finding new ways to treat neuropsychiatric disorders.

The 3D organoids, developed from stem cells to resemble a simplified model of the human cortex, connected and integrated with the surrounding tissue in each rat’s cortex to form a functional part of the rodent’s own brain, displaying activity related to sensory perception.

This, according to a team of researchers led by neuroscientist Sergiu Pașca of Stanford University, overcomes the limitations of dish-grown organoids, and gives us a new platform for modeling human brain development and disease in a living system.
