AI can see what’s on your screen by reading HDMI electromagnetic radiation

Shiver me timbers: Security researchers have demonstrated that it’s possible to spy on what’s visible on your screen by intercepting electromagnetic radiation from video cables with great accuracy, thanks to artificial intelligence. The team from Uruguay’s University of the Republic says their AI-powered cable-tapping method is good enough that these attacks are likely already happening.

Back in the analog video era, it was relatively straightforward for hackers to reconstruct what was on a screen by detecting the leakage from video cables. But once digital protocols like HDMI took over, that became much trickier. The data zipping through HDMI is much more complex than old analog signals.

However, those digital signals still leak some electromagnetic radiation as they transmit between your computer and display. By training an AI model on samples of matching original and intercepted HDMI signals, the researchers were able to decode those leaks into readable screen captures.

Peculiar Rock Found by NASA’s Perseverance Rover Leaves Scientists Puzzled

“These spots are a big surprise,” said Dr. David Flannery. “On Earth, these types of features in rocks are often associated with the fossilized record of microbes living in the subsurface.”

Did Mars once have life billions of years ago? This is what NASA’s Perseverance (Percy) rover hopes to figure out, and scientists might be one step closer to answering that question with a recent discovery by the car-sized robotic explorer that found a unique rock with “leopard spots” that have caused some in the scientific community to claim this indicates past life might have once existed on the now cold and dry Red Planet. However, others have just as quickly rushed to say that further evidence is required before jumping to conclusions.

Upon analyzing the rock using Percy’s intricate suite of scientific instruments, scientists determined that it contained specific chemical signatures indicative of life possibly having existed billions of years ago when liquid water flowed across the surface. However, the science team is also considering other reasons for the rock’s unique appearance, including further research to determine if the findings are consistent with potential ancient life.

The unique features of the rock include calcium sulfate veins with reddish material between the veins which indicate the presence of hematite, which is responsible for the Red Planet’s rusty color. Upon further inspecting the reddish material, Percy identified dozens of off-white splotches at the millimeter-scale with black material surrounding it, hence the name “leopard spots”

Engineers send 3D Printer into Space

Imagine a crew of astronauts headed to Mars. About 140 million miles away from Earth, they discover their spacecraft has a cracked O-ring. But instead of relying on a dwindling cache of spare parts, what if they could simply fabricate any part they needed on demand?

A team of Berkeley researchers, led by Ph.D. student Taylor Waddell, may have taken a giant leap toward making this option a reality. On June 8, they sent their 3D printing technology to space for the first time as part of the Virgin Galactic 7 mission.

Their next-generation microgravity printer—dubbed SpaceCAL—spent 140 seconds in suborbital space while aboard the VSS Unity space plane. In that short time span, it autonomously printed and post-processed a total of four test parts, including space shuttles and benchy figurines from a liquid plastic called PEGDA.

NVIDIA adds tools it says will accelerate development of humanoid robots

NVIDIA workflows connect real and synthetic data

Training foundation models for humanoid and other robots typically requires large amounts of data, noted NVIDIA. Teleoperation is one way to capture human demonstration data, but it can be expensive and time-consuming, it said.

NVIDIA announced a workflow that uses AI and Omniverse to enable developers to train robots with smaller amounts of data than previously required. First, developers use Apple Vision Pro to capture a relatively small number of teleoperated demonstrations.

How AI is fixing traffic lights | Project Green Light

We’re using AI and Google Maps driving trends to optimize traffic light patterns and improve traffic flow. Stop-and-go traffic in urban areas causes 29 times more emissions than on open roads. Researchers at Google are partnering with cities around the globe, from Rio to Jakarta. So far, local governments have saved fuel and lowered emissions for nearly 30 million car rides every month.

As new tech threatens jobs, Silicon Valley promotes no-strings cash aid

Sam Altman, CEO of OpenAI,… said some kind of national payments would likely be needed as technology killed more jobs even as it generated massive wealth for others.

Many tech entrepreneurs have long suggested that guaranteed income could cushion job losses from AI and automation. The latest and largest study of the idea was spearheaded by the man behind ChatGPT.

Google DeepMind’s new AI systems can now solve complex math problems

AI models can easily generate essays and other types of text. However, they’re nowhere near as good at solving math problems, which tend to involve logical reasoning—something that’s beyond the capabilities of most current AI systems.

But that may finally be changing. Google DeepMind says it has trained two specialized AI systems to solve complex math problems involving advanced reasoning. The systems—called AlphaProof and AlphaGeometry 2—worked together to successfully solve four out of six problems from this year’s International Mathematical Olympiad (IMO), a prestigious competition for high school students. They won the equivalent of a silver medal.
