The competition will focus on testing the participants’ physical and mental strength in preparation for spaceflight.
Bottom dollar.
Bloomberg today reported that a shortage of inexpensive display driver chips has delayed production of the LCD panels used in, well, pretty much every product category you can think of. Displays are ubiquitous, and many devices can’t function without them. But for the displays to work, they require a display driver — no, not Nvidia or AMD display drivers, those are software. We’re talking about a tiny chip that sends instructions and signals to the display.
That’s a fairly simple function, at least compared to those performed by the vastly more powerful components inside the device proper, which is why many display drivers cost $1. But a component’s price doesn’t always reflect its importance, as anyone who’s built a high-end PC, bought one of the best gaming monitors, and then realized they forgot to get a compatible cable can attest. That missing link is both cheap and vital.

A team of polymer science and engineering researchers at the University of Massachusetts Amherst has demonstrated for the first time that the positions of tiny, flat, solid objects integrated in nanometrically thin membranes—resembling those of biological cells—can be controlled by mechanically varying the elastic forces in the membrane itself. This research milestone is a significant step toward the goal of creating ultrathin flexible materials that self-organize and respond immediately to mechanical force.
The team has discovered that rigid solid plates in biomimetic fluid membranes experience interactions that are qualitatively different from those of biological components in cell membranes. In cell membranes, fluid domains or adherent viruses experience either attractions or repulsions, but not both, says Weiyue Xin, lead author of the paper detailing the research, which recently appeared in Science Advances. But in order to precisely position solid objects in a membrane, both attractive and repulsive forces must be available, adds Maria Santore, a professor of polymer science and engineering at UMass. In the Santore Lab at UMass, Xin used giant unilamellar vesicles, or GUVs, which are cell-like membrane sacks, to probe the interactions between solid objects in a thin, sheet-like material. Like biological cells, GUVs have fluid membranes and form a nearly spherical shape. Xin modified the GUVs so that the membranes included tiny, solid, stiff plate-like masses.
Commentary: We like to imagine an AI-driven future, but it’s machine learning that will actually help us to progress, argues expert Michael I. Jordan.
Remote-controlled Venus flytrap “robo-plants” and crops that tell farmers when they are hit by disease could become reality after scientists developed a high-tech system for communicating with vegetation.
Researchers in Singapore linked up plants to electrodes capable of monitoring the weak electrical pulses naturally emitted by the greenery.
The scientists used the technology to trigger a Venus flytrap to snap its jaws shut at the push of a button on a smartphone app.
Summary: Dopamine neurons largely rely on their own discharge to determine release rates of the hormone, researchers report.

In addition to smoothing out wrinkles, researchers have found that the drug Botox can reveal the inner workings of the brain. A new study used it to show that feedback from individual nerve cells controls the release of dopamine, a chemical messenger involved in motivation, memory, and movement.
Machine learning (ML) models are only as good as the data you feed them. That’s true during training, but also once a model is put in production. In the real world, the data itself can change as new events occur and even small changes to how databases and APIs report and store data could have implications on how the models react. Since ML models will simply give you wrong predictions and not throw an error, it’s imperative that businesses monitor their data pipelines for these systems.
That’s where tools like Aporia come in. The Tel Aviv-based company today announced that it has raised a $5 million seed round for its monitoring platform for ML models. The investors are Vertex Ventures and TLV Partners.
For 50 years, AeroVironment has advanced UAV development. Today, the company is a Technology Solutions Provider at the intersection of four future-defining technologies: robotics, sensors, analytics and connectivity. Its culture of experimentation and R&D dates back to its founder, Dr. Paul MacCready Jr., whose achievements earned him the nickname “the father of human-powered flight”. From deploying the world’s most popular sUAS to designing the helicopter that’s en route to fly in Mars’ thin atmosphere, AeroVironment’s collective accomplishments provide a case study of imagination, innovation and collaboration — one that has and will bring effective solutions to frontlines, farms and frontiers, yesterday, today and tomorrow.
Leading the Way: UAS Capabilities – Onward and Upward
From solar-powered aircraft to the first hand-launched small UAS (sUAS) for military reconnaissance, AeroVironment literally launched the era of small aerial vehicles for environmental, commercial and defense purposes. For 35 years, the company has made its UAVs smaller and simpler, yet with multiple and ever-more-innovative functionality.
Days after the first malware targeting Apple M1 chips was discovered in the wild, researchers have disclosed yet another previously undetected piece of malicious software that was found in about 30000 Macs running Intel x86_64 and the iPhone maker’s M1 processors.
However, the ultimate goal of the operation remains something of a conundrum, what with the lack of a next-stage or final payload leaving researchers unsure of its distribution timeline and whether the threat is just under active development.
Calling the malware “Silver Sparrow,” cybersecurity firm Red Canary said it identified two different versions of the malware — one compiled only for Intel x86_64 and uploaded to VirusTotal on August 31, 2020 (version 1), and a second variant submitted to the database on January 22 that’s compatible with both Intel x86_64 and M1 ARM64 architectures (version 2).
