NASA CANS BOEING’S STARLINER AMID SAFETY CONCERNS
A decade ago, NASA awarded Boeing $4.2 billion to develop the Starliner spacecraft, aiming to end reliance on Russia for crew transport to the International Space Station (ISS). However, Boeing’s Starliner has faced significant setbacks, including thruster failures and helium leaks, leading NASA to switch the returning astronauts to a SpaceX Crew Dragon. NASA’s lack of confidence in Starliner’s safety is evident, and it is unlikely Boeing will meet its target of six missions before the ISS’s potential retirement in 2030. Boeing has already incurred $1.6 billion in charges for delays. Despite assurances from Boeing’s CEO, the company must address design flaws, particularly in the spacecraft’s propulsion system. NASA’s decision underscores its commitment to safety and could delay future crewed Starliner flights until at least 2026, potentially limiting Boeing’s ability to fulfill its contract. Meanwhile, SpaceX continues to successfully conduct crew missions and may remain NASA’s primary option. (Ars Technica)
SEATTLE AIRPORT HIT BY POSSIBLE CYBERATTACK DISRUPTIONS
The Port of Seattle, which manages Seattle-Tacoma International Airport, reported a “possible cyberattack” affecting its websites and phone systems. Outages began early Saturday, with the airport confirming system disruptions but no estimated time for full restoration. Travelers are advised to use airline apps for boarding passes and allow extra time. As of Sunday morning, the Port’s public-facing web infrastructure remained largely offline. A TSA spokesperson confirmed that security operations were unaffected. This incident follows a recent global IT issue caused by a CrowdStrike software update, which also disrupted flight operations.

GPT MODELS EXCEL IN MULTILINGUAL TEXT ANALYSIS STUDY
Automated text analysis is increasingly used in the social and behavioral sciences to assess psychological constructs from text. Research evaluated whether GPT, the large language model behind ChatGPT, can effectively perform this task in multiple languages. Analyzing 47,925 annotated tweets and news headlines across 12 languages, GPT models (3.5 Turbo, 4, and 4 Turbo) demonstrated higher accuracy in detecting constructs like sentiment, emotions, offensiveness, and moral foundations, with correlation coefficients ranging from 0.59 to 0.77, compared to 0.20 to 0.30 for traditional dictionary-based methods. GPT’s performance, which improved with newer versions, was comparable to or better than some specialized machine learning models and offered cost efficiency. GPT’s ease of use and broad language support make it a valuable tool for automated text analysis, potentially advancing research in less-studied languages and making sophisticated natural language processing more accessible.

EDINBURGH SCIENTISTS USE BACTERIA TO RECOVER RARE METALS
Scientists at the University of Edinburgh are pioneering a novel approach to tackle climate change by utilizing bacteria to extract rare metals crucial for green technology. This initiative aims to recover lithium, cobalt, manganese, and other essential minerals from discarded batteries and electronic waste. Professor Louise Horsfall emphasizes the growing dependence on these metals for technologies like electric cars, solar panels, and wind turbines. With China dominating the supply and processing of rare earth elements, there is a pressing need for a circular economy to recycle these materials effectively. The team has demonstrated that bacteria can isolate and recover metals from waste, with future plans to use gene-edited strains to enhance extraction. The ultimate goal is to show that recycled metals can be used in new devices, supporting the transition to a circular economy for green technologies, as mandated by upcoming legislation.

ROUTINE VACCINATION COVERAGE STABLE BUT HPV RATES DECLINE
Vaccinations are crucial for protecting individuals and communities from serious diseases. The Advisory Committee on Immunization Practices recommends routine vaccines for adolescents aged 11–12, including the tetanus, diphtheria, and pertussis vaccine; quadrivalent meningococcal conjugate vaccine; and human papillomavirus (HPV) vaccine. A 2023 analysis of the National Immunization Survey-Teen data, involving 16,658 adolescents aged 13–17, found that vaccination coverage remained consistent with 2022 levels. Coverage among adolescents eligible for the Vaccines for Children (VFC) program remained stable during the COVID-19 pandemic, though there was a decline in HPV vaccination rates for those born in 2010 compared to earlier birth years. Differences in coverage between VFC-eligible and non-VFC-eligible adolescents persisted before the pandemic but were less pronounced in recent years. Healthcare providers should strongly recommend all routine vaccines and check vaccination records to ensure adolescents are up to date. (CDC)
6,000-YEAR-OLD DOLMEN SHOWS ADVANCED NEOLITHIC ENGINEERING
The Dolmen of Menga, built nearly 6,000 years ago in southern Spain, showcases advanced Neolithic engineering. Recent analysis using high-resolution laser scans and old excavation data reveals the construction techniques of this massive stone chamber. The dolmen, predating Stonehenge by 1,000 years, involved transporting 32 large stone blocks from a quarry one kilometer away. The largest capstone is 8 meters long and weighs 150 tonnes. Builders used wooden tracks to move stones and precise counterweights and ramps to place them accurately. Carved facets on the stones ensured a snug fit. Despite being in a seismically active area, the dolmen remains intact, demonstrating the builders’ impressive understanding of physics and geometry. This study underscores their engineering prowess, comparable to later structures like Stonehenge. (Nature)
POLARIS DAWN TO FEATURE FIRST PRIVATE SPACEWALK IN HISTORY
Jared Isaacman, who led the historic Inspiration4 mission three years ago, is preparing for another spaceflight with Polaris Dawn. This mission, set to launch next week, will be the first private spacewalk and aims to push the boundaries of commercial space travel. Polaris Dawn, in collaboration with SpaceX, will travel farther from Earth than any mission since Apollo 17. The Crew Dragon capsule will enter an elliptical orbit reaching 870 miles above Earth, surpassing the Gemini XI record. The mission will include a spacewalk, with astronauts Isaacman and Sarah Gillis conducting tests outside the spacecraft. They will also gather data on space radiation and test new technologies. Polaris Dawn represents a significant step toward Elon Musk’s vision of Mars exploration, demonstrating the potential of commercial space endeavors. (New York Times)
