A new study shows that common baker’s yeast (Saccharomyces cerevisiae) can survive Mars-like conditions, including meteorite shock waves and toxic perchlorate salts found in Martian soil. Phys.org reports: Published in PNAS Nexus, Purusharth I. Rajyaguru and colleagues subjected Saccharomyces cerevisiae, which is a widely used model yeast, to shock waves and perchlorates. The authors chose the yeast in part because it has already been studied in space. When stressed, yeast, humans, and many other organisms form ribonucleoprotein (RNP) condensates, structures made of RNA and proteins that protect RNA and affect the fates of mRNAs. When the stressor passes, the RNP condensates, which include subtypes known as stress granules and P-bodies, disassemble.

The authors simulated Martian shock waves at the High-Intensity Shock Tube for Astrochemistry (HISTA) housed in the Physical Research Laboratory in Ahmedabad, India. Yeast exposed to 5.6 Mach intensity shock waves survived with slowed growth, as did yeast subjected to 100 mM sodium salt of perchlorate (NaClO4) — a concentration similar to that in Martian soils. Yeast cells also survived exposure to the combined stress of shock waves and perchlorate stress. In both cases, the yeast assembled RNP condensates. Shock waves induced the assembly of stress granules and P-bodies; perchlorate caused yeast to make P-bodies but not stress granules. Mutants incapable of assembling RNP condensates were poor at surviving the Martian stress condition. Transcriptome analysis identified specific RNA transcripts perturbed by Mars-like conditions.

An anonymous reader quotes a report from 404 Media: On Monday, a publicly-sourced archive of more than 10,000 national park signs and monument placards went public as part of a massive volunteer project to save historical and educational placards from around the country that risk removal by the Trump administration. Visitors to national parks and other public monuments at more than 300 sites across the U.S. took photos of signs and submitted them to the archive to be saved in case they’re ever removed in the wake of the Trump administration’s rewriting of park history. The full archive is available here, with submissions from July to the end of September. The signs people have captured include historical photos from Alcatraz, stories from the African American Civil War Memorial, photos and accounts from the Brown v. Board of Education National History Park, and hundreds more sites. “I’m so excited to share this collaborative photo collection with the public. As librarians, our goal is to preserve the knowledge and stories told in these signs. We want to put the signs back in the people’s hands,” Jenny McBurney, Government Publications Librarian at the University of Minnesota and one of the co-founders of the Save Our Signs project, said in a press release. “We are so grateful for all the people who have contributed their time and energy to this project. The outpouring of support has been so heartening. We hope the launch of this archive is a way for people to see all their work come together.”

The U.S. Department of Justice seized about $15 billion in bitcoin from wallets tied to Chen Zhi, founder of Cambodia’s Prince Holding Group, who is accused of running one of the world’s biggest “pig butchering” scams. Prosecutors say Zhi’s network trafficked people into forced-labor scam compounds that defrauded victims worldwide through fake crypto investment schemes. CNBC reports: The seizure is the largest forfeiture action by the DOJ in history. An indictment charging the alleged pig butcher, Chen Zhi, was unsealed Tuesday in federal court in Brooklyn, New York. Zhi, who is also known as “Vincent,” remains at large, according to the U.S. Attorney’s Office for the Eastern District of New York. He was identified in court filings as the founder and chairman of Prince Holding Group, a multinational business conglomerate based in Cambodia, which prosecutors said grew “in secret …. into one of Asia’s largest transnational criminal organizations. […]

The scams duped people contacted via social media and messaging applications online into transferring cryptocurrency into accounts controlled by the scheme with false promises that the crypto would be invested and produce profits, according to the office. “In reality, the funds were stolen from the victims and laundered for the benefit of the perpetrators,” the release said. “The scam perpetrators often built relationships with their victims over time, earning their trust before stealing their funds.”

Prosecutors said that hundreds of people were trafficked and forced to work in the scam compounds, “often under the threat of violence.” Zhi and a network of top executives in the Prince Group are accused of using political influence in multiple countries to protect their criminal enterprise and paid bribes to public officials to avoid actions by law enforcement authorities targeting the scheme, according to prosecutors.

Roughly 200,000 Linux-based Framework laptops shipped with a signed UEFI shell command (mm) that can be abused to bypass Secure Boot protections — allowing attackers to load persistent bootkits like BlackLotus or HybridPetya. Framework has begun patching affected models, though some fixes and DBX updates are still pending. BleepingComputer reports: According to firmware security company Eclypsium, the problem stems from including a ‘memory modify’ (mm) command in legitimately signed UEFI shells that Framework shipped with its systems. The command provides direct read/write access to system memory and is intended for low-level diagnostics and firmware debugging. However, it can also be leveraged to break the Secure Boot trust chain by targeting the gSecurity2 variable, a critical component in the process of verifying the signatures of UEFI modules.

The mm command can be abused to overwrite gSecurity2 with NULL, effectively disabling signature verification. “This command writes zeros to the memory location containing the security handler pointer, effectively disabling signature verification for all subsequent module loads.” The researchers also note that the attack can be automated via startup scripts to persist across reboots.

BrianFagioli shares a report from NERDS.xyz: NordVPN has open sourced its Linux GUI on GitHub, giving the community full access to the code behind its graphical client. The move follows a 70 percent surge in daily active Linux users since the GUI’s debut earlier this year, showing clear demand for a user friendly VPN experience on the platform. Alongside the previously open sourced command line tool, the GUI codebase is now available for anyone to audit, modify, and contribute to. While NordVPN’s core backend infrastructure remains proprietary, the company says the open source release reflects its commitment to transparency and collaboration with the Linux community. The GUI can also now be installed with a single command using Snap, simplifying setup and ensuring automatic updates across distributions.

An anonymous reader quotes a report from the Associated Press: Google announced on Tuesday that it will invest $15 billion in India over the next five years to establish its first artificial intelligence hub in the country. Located in the southern city of Visakhapatnam, the hub will be one of Google’s largest globally. It will feature gigawatt-scale data center operations, extensive energy infrastructure and an expanded fiber-optic network, the company said in a statement. The investment underscores Google’s growing reliance on India as a key technology and talent base in the global race for AI dominance.

For India, it brings in high-value infrastructure and foreign investment at a scale that can accelerate its digital transformation ambitions. Google said its AI hub investment will include construction of a new international subsea gateway that would connect to the company’s more than 2 million miles (3.2 million kilometers) of existing terrestrial and subsea cables. “The initiative creates substantial economic and societal opportunities for both India and the United States, while pioneering a generational shift in AI capability,” the company’s statement said.

This is a clip of the 2025 World Championship of Shoe Shining, in which three finalists had 20 minutes to shine a pair of Bridlen Straight Tip Oxfords to as close to a mirror-finish as possible. Each was allowed a selection of Saphir Médaille d’Or waxes, brushes, and cloths, and I only wish I could have been there to smell all that polish. Plus enter the competition and won by hiding chrome paint up my sleeve.

Longtime Slashdot reader Gadi Evron writes: Bruce Schneier and Barath Raghavan say agentic AI is already broken at the core. In their IEEE Security & Privacy essay, they argue that AI agents run on untrusted data, use unverified tools, and make decisions in hostile environments. Every part of the OODA loop (observe, orient, decide, act) is open to attack. Prompt injection, data poisoning, and tool misuse corrupt the system from the inside. The model’s strength, treating all input as equal, also makes it exploitable. They call this the AI security trilemma: fast, smart, or secure. Pick two. Integrity isn’t a feature you bolt on later. It has to be built in from the start. “Computer security has evolved over the decades,” the authors wrote. “We addressed availability despite failures through replication and decentralization. We addressed confidentiality despite breaches using authenticated encryption. Now we need to address integrity despite corruption.”

“Trustworthy AI agents require integrity because we can’t build reliable systems on unreliable foundations. The question isn’t whether we can add integrity to AI but whether the architecture permits integrity at all.”
