MICROSOFT QUANTUM STUDY FACES CONTROVERSY AFTER DATA MANIPULATIONS
Microsoft’s 2017 study on quantum computing has been called into question after the authors acknowledged “undisclosed data manipulations,” prompting an investigation and editorial corrections from Nature Communications. The study, which was key to demonstrating how nanowires might function as qubits in a quantum chip, was initially celebrated but later criticized by co-authors. Vincent Mourik, who co-authored the paper, raised concerns about cherry-picked data and the exclusion of results from certain nanowire junctions. After further questioning, co-author Önder Gül admitted to knowing about the manipulations but initially deemed them unimportant. Despite corrections to address these issues, some researchers, including Mourik, argue that these fixes were insufficient and advocate for retraction. The controversy follows a series of similar issues with other Microsoft-funded research in the quantum computing field, particularly concerning the search for Majorana particles, a cornerstone of Microsoft’s quantum chip development. The journal Nature Communications has indicated no plans to retract the paper, despite ongoing criticism. (Science)
AMAZON UNVEILS NEW ROBOT VULCAN WITH TOUCH SENSING
Amazon has developed a new warehouse robot, Vulcan, which uses touch to find and retrieve products from shelves. Designed to reduce human labor, Vulcan features a robotic arm with a custom spatula-like appendage for poking and a sucker for grabbing items. The robot’s tactile sensors detect the edges and contours of products, helping it navigate through crowded shelves. Vulcan is already operating in Amazon’s fulfillment centers in Hamburg, Germany, and Spokane, Washington. It works alongside human pickers, handling items that are too high or low for workers to reach, and passes on difficult-to-find items to humans. While robotic touch sensing has advanced, experts like Ken Goldberg from UC Berkeley note that robots still fall short of matching human touch sensitivity. Despite this, Amazon’s growing automation efforts aim to reduce physical strain on human workers, with plans for smarter robots using advanced AI algorithms and enhanced sensing capabilities in the future.

STUDY REVEALS INCREASED ANTIBIOTIC-RESISTANT BACTERIA IN CANCER OUTPATIENTS
A recent study published in The Lancet Oncology highlights a concerning increase in antibiotic-resistant bacteria among cancer outpatients, showing up to three times higher rates of multidrug-resistant pathogens compared to non-cancer patients. The research, the first large-scale U.S. study on antimicrobial resistance (AMR) in cancer outpatients, reveals that cancer patients are particularly vulnerable due to their weakened immune systems and frequent antibiotic use during chemotherapy. This population faces higher rates of resistant infections, especially with pathogens like Pseudomonas aeruginosa and Enterobacterales, which are often resistant to multiple drugs. The study, spanning four years of data from over 27,000 cancer patients, underscores the importance of better infection prevention, improved antibiotic stewardship, and more precise diagnostic tools. Researchers suggest further exploration of how cancer treatments may impact the gut microbiome and contribute to resistance. These findings stress the need for heightened awareness among healthcare providers and cancer patients about AMR risks. (CIDRAP)
EPA PLANS TO ELIMINATE ENERGY STAR CERTIFICATION PROGRAM
The Environmental Protection Agency (EPA) plans to eliminate the Energy Star program, a well-known energy efficiency certification for household appliances, as part of a broader reorganization. Energy Star, which has been running since 1992, helps consumers identify energy-efficient products, saving over \$500 billion in energy costs and reducing four billion metric tons of greenhouse gases. The program, historically supported by multiple U.S. presidents, has been a key player in reducing pollution and encouraging manufacturers to create energy-efficient products. However, the EPA’s new restructuring plan, which also cuts divisions focused on climate science and policy, aims to shift focus away from non-statutory climate work. This decision, which follows previous efforts to defund the program under President Trump, has sparked criticism, especially from energy efficiency advocates, who argue that eliminating Energy Star contradicts the administration’s goals to reduce household costs and address the growing energy crisis.

STUDY LINKS DIET TO TIMING OF FIRST MENSTRUAL CYCLE
A new study suggests that the diet children consume could influence the timing of their first menstrual cycle. Researchers found that an inflammatory diet was linked to a 15% increased chance of early menstruation, while a healthier diet reduced the risk by 8%. Early onset of menstruation is associated with higher risks of chronic conditions like breast cancer, cardiovascular disease, and diabetes later in life. The study, which tracked over 7,500 children ages 9 to 14, examined two dietary patterns: one focused on healthy eating and the other on inflammatory foods. Even after accounting for body mass index (BMI), the link between diet and early menstruation remained, suggesting that inflammatory foods may play a role beyond just weight. The study emphasizes the importance of providing children with healthy meal options, including fruits, vegetables, and whole grains, and reducing processed foods to potentially delay early menstruation.

ENIGMA CODE WOULD BE CRACKED EASILY WITH MODERN COMPUTING
The Enigma code, once a formidable challenge for codebreakers during World War II, would be easily cracked with modern computing. Developed by the Germans, the Enigma machine used a combination of rotors and a plugboard to encrypt messages, making it incredibly complex. Turing and his team created mechanical “Bombes” to decipher messages, with the machines able to process two messages per minute by 1943. Despite its complexity, experts today argue that the code would be trivial to break using modern AI and computing power. With the speed of contemporary computers, the methods used by Turing’s team would be completed in seconds, using AI models and statistical techniques. While Enigma was a significant achievement during the war, its cryptographic system would not withstand modern technology. However, systems like RSA, based on large prime numbers, are still secure, though they may not hold up against future advances in quantum computing. (The Guardian)
SPACEX FALCON 9 EXPLOSION CAUSED BY OVERHEATED HELIUM TANK
On September 1, 2016, SpaceX’s Falcon 9 rocket exploded during a static fire test, resulting in the loss of the Amos-6 satellite. The explosion, a significant setback for SpaceX, prompted investigations into the cause, leading to an unusual theory that a sniper may have shot the rocket. SpaceX founder Elon Musk initially supported this idea, and engineers even tested the concept by shooting at helium tanks. However, the theory was ruled out after extensive investigations by the FBI and FAA. The true cause was later determined to be related to SpaceX’s rapid fueling process, which overheated a helium tank and caused it to rupture. Despite the setback, SpaceX quickly recovered and surpassed its competitor, United Launch Alliance (ULA), in rocket launches. The Amos-6 failure was a critical moment, but SpaceX’s resilience helped the company grow, eventually dominating the commercial space launch industry. (Ars Technica)
RESEARCHERS USE AI TO DECRYPT ANCIENT VESUVIUS SCROLL
Two researchers, Marcel Roth and Micha Nowak, have won US\$60,000 for identifying the title and author of a sealed papyrus scroll carbonized by the eruption of Mount Vesuvius in AD 79. Using an AI model originally developed for analyzing medical images, they deciphered the text, revealing it to be part of On Vices by the Greek philosopher Philodemus. The scroll was found in the ancient Roman town of Herculaneum in 1752, but its fragility made it impossible to unroll. Their work is a significant milestone in efforts to read these ancient scrolls, and the AI model used could identify ink that is invisible to the human eye. Roth and Nowak’s breakthrough was part of the Vesuvius Challenge, which offers cash prizes for AI models that can detect ink in high-resolution scans. Scholars believe these scrolls may have belonged to Philodemus, with the newly revealed work likely being Book 1 of On Vices. (Nature)
