“CHIMERA” METAMATERIAL ACHIEVES PREVIOUSLY IMPOSSIBLE MULTI-TERRAIN INVISIBILITY

A new metamaterial that taps into the power of animals who camouflage themselves in nature has achieved the first successful multi-terrain invisibility, making it effectively invisible to visible, microwave, and thermal scanning techniques.

Dubbed Chimera after the multi-faceted monster of Greek mythology, the new material can achieve its previously impossible capabilities in a range of environments, much like the animals who inspired its development, offering significant potential for both scientific and military applications.

MULTI-TERRAIN INVISIBILITY INSPIRED BY UNIQUE CLASS OF ANIMAL

In nature, certain animals have adapted themselves to appear virtually invisible to both predators and prey. The most famous of these is the chameleon, which can adapt its outer appearance to match its environment almost perfectly.

However, the chameleon is not the only poikilotherm lauded for its ability to achieve a form of invisibility to aid its survival. For example, the bearded dragon is noted for its ability to conceal itself thermally by matching the temperature of its environment, while the glass frog can make itself transparent so that predators cannot see it directly.

Now, a team of researchers says they have combined the adaptive ability of all three animals to produce a metamaterial that is effectively invisible across microwave, visible, and infrared spectra to achieve previously impossible multi-terrain invisibility.

CHANCES THAT ODD SOIL SAMPLES COLLECTED AT MARS’ JEZERO CRATER CONTAIN SIGNS OF ANCIENT LIFE JUST INCREASED DRAMATICALLY

A new analysis of subsurface deposit and erosion patterns beneath the dry lakebed in Mars’ Jezero crater indicates the process took place over eons, dramatically improving the chances that soil samples collected at the site by NASA’s Perseverance could contain signs of ancient life.

Although the exact timeline for a joint European Space Agency/NASA mission to retrieve Perseverance’s soil samples has not yet been set, the fact that the lake in Jezero crater had existed across numerous geological phases significantly increases the odds of finding signs of ancient life within those samples.

RESEARCHERS HAVE LONG SUSPECTED DEEP SEDIMENTARY LAYERS LIE BENEATH JEZERO

Over the last few decades, images captured by satellites orbiting Mars have long hinted at the idea of eroded subsurface layers in the region. However, researchers knew that up close analysis by Perseverance’s ground penetrating radar was the only way to confirm those suspicions.

“From orbit, we can see a bunch of different deposits, but we can’t tell for sure if what we’re seeing is their original state or if we’re seeing the conclusion of a long geological story,” said David Paige, a UCLA professor of Earth, planetary and space sciences and first author of the paper detailing the findings. “To tell how these things formed, we need to see below the surface.”

Fortunately, Perseverance’s mission planners included the Radar Imager for Mars’ Subsurface Experiment, or RIMFAX, as one of the seven instruments on board the rover. Like ground penetrating radar used on Earth, the RIFMAX fires radar waves directly into the Mars surface, then reads their reflections as they bounce off different sedimentary layers.

AI went rogue and couldn’t be brought back in ‘legitimately scary’ study

For decades, scientists and sci-fi writers have been imagining what would happen if AI turned against us.

A world overrun by paperclips and the extermination of humankind, to cite but one famous scenario.

But now we can stop imagining what would happen if machines refused to toe the line: that line has just been crossed.

A new study has revealed that Artificial Intelligence systems are able to resist sophisticated safety methods designed to keep them in check.

The study was carried out by a team of scientists at the AI safety and research company Anthropic, who programmed various large language models (LLMs) to behave maliciously.

They then attempted to correct this behaviour using a number of safety training techniques, which were designed to root out deception and mal-intent, Live Science reports.

However, they found that regardless of the training technique or size of the model, the LLMs maintained their rebellious ways.

Indeed, one technique even backfired: teaching the AI to conceal its rogue actions during training, the team wrote in their paper, published to the preprint database arXiv.

“Our key result is that if AI systems were to become deceptive, then it could be very difficult to remove that deception with current techniques. That’s important if we think it’s plausible that there will be deceptive AI systems in the future, since it helps us understand how difficult they might be to deal with,” lead author Evan Hubinger told Live Science.

AI will increase the number and impact of cyber attacks, intel officers say

The assessment, from the UK’s Government Communications Headquarters, predicted ransomware will be the biggest threat to get a boost from AI over the next two years. AI will lower barriers to entry, a change that will bring a surge of new entrants into the criminal enterprise. More experienced threat actors—such as nation-states, the commercial firms that serve them, and financially motivated crime groups—will likely also benefit, as AI allows them to identify vulnerabilities and bypass security defenses more efficiently.

“The emergent use of AI in cyber attacks is evolutionary not revolutionary, meaning that it enhances existing threats like ransomware but does not transform the risk landscape in the near term,” Lindly Cameron, CEO of the GCHQ’s National Cyber Security Centre, said. Cameron and other UK intelligence officials said that their country must ramp up defenses to counter the growing threat.

The assessment, which was published Wednesday, focused on the effect AI is likely to have in the next two years. The chances of AI increasing the volume and impact of cyber attacks in that timeframe were described as “almost certain,” the GCHQ’s highest confidence rating. Other, more-specific predictions listed as almost certain were:

  • AI improving capabilities in reconnaissance and social engineering, making them more effective and harder to detect
  • More impactful attacks against the UK as threat actors use AI to analyze exfiltrated data faster and more effectively, and use it to train AI models
  • Beyond the two-year threshold, commoditization of AI-improving capabilities of financially motivated and state actors
  • The trend of ransomware criminals and other types of threat actors who are already using AI will continue in 2025 and beyond.

The area of biggest impact from AI, Wednesday’s assessment said, would be in social engineering, particularly for less-skilled actors.

“Generative AI (GenAI) can already be used to enable convincing interaction with victims, including the creation of lure documents, without the translation, spelling and grammatical mistakes that often reveal phishing,” intelligence officials wrote. “This will highly likely increase over the next two years as models evolve and uptake increases.”

The assessment added: “To 2025, GenAI and large language models (LLMs) will make it difficult for everyone, regardless of their level of cyber security understanding, to assess whether an email or password reset request is genuine, or to identify phishing, spoofing or social engineering attempts.”

Victory! Ring Announces It Will No Longer Facilitate Police Requests for Footage from Users

Amazon’s Ring has announced that it will no longer facilitate police’s warrantless requests for footage from Ring users. This is a victory in a long fight, not just against blanket police surveillance, but also against a culture in which private, for-profit companies build special tools to allow law enforcement to more easily access companies’ users and their data—all of which ultimately undermine their customers’ trust.

Years ago, after public outcry and a lot of criticism from EFF and other organizations, Ring ended its practice of allowing police to automatically send requests for footage to a user’s email inbox, opting instead for a system where police had to publicly post requests onto Ring’s Neighbors app. Now, Ring hopefully will altogether be out of the business of platforming casual and warrantless police requests for footage to its users. This is a step in the right direction, but has come after years of cozy relationships with police and irresponsible handling of data (for which they reached a settlement with the FTC). We also helped to push Ring to implement end-to-end encryption. Ring has been forced to make some important concessions—but we still believe the company must do more. Ring can enable their devices to be encrypted end-to-end by default and turn off default audio collection, which reports have shown collect audio from greater distances than initially assumed. We also remain deeply skeptical about law enforcement’s and Ring’s ability to determine what is, or is not, an emergency that requires the company to hand over footage without a warrant or user consent.

SCI-FI NIGHTMARE? THESE INSECT-INSPIRED MICRO-ROBOTS ARE THE SMALLEST, LIGHTEST, AND FASTEST EVER BUILT

Engineers from Washington State University (WSU) have created the smallest, lightest, and fastest micro-robots ever.

Inspired by actual mini-bugs and water striders, the insect-like micro-robots could one day be used for artificial pollination, search and rescue missions, remote environmental monitoring, micro-fabrication, or even robotic-assisted surgery.

SHAPE MEMORY ALLOY POWERS MOTION OF MICRO-ROBOTS

The waster strider-inspired micro-robot weighs only 55 milligrams, while the mini-bug-inspired robot clocks in at a paltry eight milligrams. Perhaps equally impressive, both can move at about six millimeters a second.

A typical ant weighs about 5 milligrams and can move at nearly a meter per second. While extremely slow compared to real-life insects, this is significantly faster than other micro-robots based on the same technology.

“That is fast compared to other micro-robots at this scale, although it still lags behind their biological relatives,” said Conor Trygstad, a PhD student in the School of Mechanical and Materials Engineering and lead author of the published work. An avid fly fisherman, Trygstad points out that real water striders move using an efficient rowing motion, while his micro-robot strider is currently limited to a less efficient flat flapping motion.

Fears Pentagon was ‘building killer robots in the basement’ sparked stricter AI rules, DoD official claims

Fears the Pentagon has been ‘building killer robots in the basement’ may have led to stricter AI rules that mandated all systems must be approved before deployment.

The Department of Defense (DoD) recently updated its AI rules among ‘a lot of confusion about’ how it plans to use self-decision-making machines on the battlefield, according to the deputy assistant defense secretary.

Michael Horowitz explained at an event this month that the ‘directive does not prohibit the development of any systems,’ but will ‘make clear what is and isn’t allowed’ and uphold a ‘commitment to responsible behavior,’ as it develops lethal autonomous systems.

While the Pentagon believes the changes should ease the public’s minds, some have said they are not ‘convinced’ by the efforts.

News of the update to the Pentagon’s 2012 ‘Autonomy in Weapon Systems,’ has sparked a debate online with many people saying ‘If the Pentagon says they’re not doing it, they’re doing it.’

Dailymail.com has reached out to the DoD for comment. 

The DoD has been aggressively pushing to modernize its arsenal with autonomous drones, tanks, and other weapons that select and attack a target without human intervention.

Mark Brakel, director of the advocacy organization Future of Life Institute (FLI), told DailyMail.com: ‘These weapons carry a massive risk of unintended escalation.’

He explained that AI-powered weapons could misinterpret something, like a ray of sunlight, and perceive it as a threat, thus attacking foreign powers without cause.

Brakel said the result could be devastating because ‘without meaningful human control, AI-powered weapons are like the Norwegian rocket incident [a near nuclear armageddon] on steroids and they could increase the risk of accidents in hotspots such as the Taiwan Strait.’

Facial recognition used after Sunglass Hut robbery led to man’s wrongful jailing, says suit

A 61-year-old man is suing Macy’s and the parent company of Sunglass Hut over the stores’ alleged use of a facial recognition system that misidentified him as the culprit behind an armed robbery and led to his wrongful arrest. While in jail, he was beaten and raped, according to his suit.

Harvey Eugene Murphy Jr was accused and arrested on charges of robbing a Houston-area Sunglass Hut of thousands of dollars of merchandise in January 2022, though his attorneys say he was living in California at the time of the robbery. He was arrested on 20 October 2023, according to his lawyers.

According to Murphy’s lawsuit, an employee of EssilorLuxottica, Sunglass Hut’s parent company, worked with its retail partner Macy’s and used facial recognition software to identify Murphy as the robber. The image that was put through the facial recognition system came from low-quality cameras, according to the lawsuit. While Houston police department was investigating the armed robbery, the EssilorLuxottica employee called police to say they could stop the investigation because the employee had identified one of two robbers with the technology. The employee also said the system had pointed to Murphy as committing two other robberies, according to the lawsuit.

When Murphy returned to Texas from California, he went to the department of motor vehicles (DMV) to renew his license. Within minutes of identifying himself to a DMV clerk, Murphy told the Guardian he was approached by a police officer who notified him there was a warrant out for his arrest for an aggravated robbery. Murphy said he was not told any details about his supposed crime except for the date the robbery occurred. He realized he was in Sacramento, California, at the time of the robbery – more than a thousand miles away.

“I almost thought it was a joke,” Murphy said.

Still, he was arrested and taken to the local county jail, where he was held for 10 days before being transferred to and processed in Harris county jail.

After a few days at Harris county, his alibi was confirmed by both his court-appointed defense attorney and the prosecutor, and the charges against him were ultimately dropped, according to the lawsuit.

Murphy was never convicted of a crime. Nonetheless, he says his detainment left him with deep scars. He was brutally beaten and gang-raped by three other men in the jail hours before he was released, he alleges. They threatened to kill him if he tried to report them to the jail staff, according to Murphy. After the alleged attack, Murphy remained in the same cell as them until he was released.

“That was kind of terrifying,” Murphy said. “Your anxiety is up so high, you’re still shaking the entire time. And I just got up on my bunk and just faced the wall and was just praying that something would come through and get me out of that tank.”

“The attack left him with permanent injuries that he has to live with every day of his life,” the lawsuit reads. “All of this happened to Murphy because the Defendants relied on facial recognition technology that is known to be error prone and faulty.”

Murphy did not realize facial recognition technology may have been used as evidence against him until two weeks ago, when he began working with his attorney, Daniel Dutko.

Dutko said he discovered from police documents that the Sunglass Hut worker shared camera footage with Macy’s, which employees from the department store chain used to identify Murphy. After that, Macy’s and Sunglass Hut contacted the police together, according to Dutko. Though Macy’s has retail partnerships with the eyewear brand in several locations, Macy’s had no connection to this robbery as the Sunglass Hut in question is a standalone location, he said.

“We feel very comfortable saying facial recognition software is the only possible explanation, and it’s the only reason why [Sunglass Hut] would go to Macy’s to try to identify him,” Dutko said.

SCIENTISTS SUCCESSFULLY TRAP INDIVIDUAL KRYPTON ATOMS TO CREATE THE FIRST-EVER ONE-DIMENSIONAL GAS

Scientists from the University of Nottingham’s School of Chemistry say they have successfully trapped individual krypton atoms to create the world’s first-ever one-dimensional gas. The atoms of Krypton (Kr), a noble gas, were trapped inside a carbon nanotube using an advanced version of transmission electron microscopy (TEM).

“As far as we know, this is the first time that chains of noble gas atoms have been imaged directly, leading to the creation of a one-dimensional gas in a solid material,” said Professor Paul Brown, director of the Nanoscale and Microscale Research Centre (nmRC), University of Nottingham.

In the future, the team says they are planning to employ electron microscopy to directly image temperature-controlled phase transitions and chemical reactions in these types of one-dimensional systems, which may “unlock the secrets” of such unusual states of matter.

RAYTHEON IS BUILDING TWO ULTRA-HIGH POWER DIRECTED ENERGY WEAPONS FOR THE U.S. NAVY AND AIR FORCE

Defense contractor Raytheon has been tasked with designing, building, and testing a pair of directed energy weapons for the U.S. Navy and U.S. Air Force. Unlike cutting-edge laser systems that use the power of light to down airborne threats, the new weapons will use ultra-powerful microwave emitters to fry the electronics of attacking drones, missiles, and other electronically guided ordinance.

According to RTX Corporation, which owns Raytheon, the two prototypes are expected to be delivered in 2024 and 2026, respectively.

DIRECTED ENERGY WEAPONS INCREASINGLY VALUABLE IN ASYMMETRICAL WARFARE

Traditional munitions like bullets use kinetic force to damage or destroy attacking vehicles and personnel. Unfortunately, the cost of more accurate systems like guided missiles is often prohibitively disproportionate when compared to the cost of the attacking vehicle.

For example, the Israeli Iron Dome system that uses missiles can cost as much as $100,000 per shot to bring down a drone or mortar that costs a mere fraction of that amount. Further complicating the issue is the fact that adversaries are increasingly using drones to mount attacks, including the October 7th, 2023, attack on Israel.

To counter what officials have termed asymmetrical threats, the Israeli government has installed a battery of laser cannons known as Iron Beam. According to an April 2022 tweet by Israeli Prime Minister Naftali Bennet, Iron Beam can down incoming mortar and drones at the cost of only $3.50 per shot.
