U.S. aid helped two African countries rein in HIV. Then came Trump

The U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) has been instrumental in combating HIV/AIDS in Africa, initiating treatment for 21 million people and saving 26 million lives. However, the Trump administration’s significant cuts to foreign aid have jeopardized these achievements, leading to concerns about the resurgence of HIV/AIDS in affected regions. The reduction in funding has disrupted treatment programs and hindered the progress made over the years. Health experts warn that the withdrawal of support could reverse the gains in controlling the epidemic, emphasizing the need for sustained international assistance to maintain and advance HIV/AIDS interventions in Africa.

Rocket crashes as gene therapy patient dies, FDA imposes hold

Rocket Pharmaceuticals has halted its Phase 2 trial of the gene therapy RP-A501 for Danon disease after a patient developed capillary leak syndrome and subsequently died from an acute systemic infection. The FDA imposed a clinical hold to investigate the adverse events. The company had added a C3 inhibitor to the pretreatment regimen to mitigate immune responses, which may have contributed to the complications. This incident raises concerns about the safety of gene therapies and the need for thorough evaluation of treatment protocols. Rocket is reassessing its approach to ensure patient safety before proceeding with further trials. (Fierce Biotech)

What to Know About the New COVID-19 Variant NB.1.8.1

The NB.1.8.1 COVID-19 variant, part of the Omicron family, has become the dominant strain in China, leading to increased hospitalizations. Detected in travelers from multiple countries, including the U.S., it exhibits symptoms similar to other variants but may have enhanced transmissibility. Current vaccines are expected to offer protection against severe disease. However, U.S. health authorities have adjusted vaccination recommendations, potentially limiting access for healthy children and adults until more safety data is available. Ongoing monitoring and vaccine updates are essential to address the evolving threat posed by NB.1.8.1. (Time)

DeepSeek Quietly Releases Upgraded R1 AI Model, Intensifying Global AI Race

Chinese startup DeepSeek has quietly released an upgraded version of its R1 artificial intelligence reasoning model on Hugging Face, without a formal announcement. The company gained global attention earlier this year when its original R1 model, developed rapidly and at low cost, outperformed major competitors like Meta and OpenAI. This unexpected success rattled markets, leading to sharp declines in the value of U.S. tech stocks, including Nvidia, although they have since recovered. The new model, like its predecessor, focuses on logical, step-by-step reasoning tasks and now ranks just behind OpenAI’s o4-mini and o3 on benchmarking site LiveCodeBench. DeepSeek’s continued innovation highlights the resilience and advancement of Chinese AI firms, even as U.S. export restrictions attempt to limit their access to key technologies like advanced chips. Nvidia CEO Jensen Huang criticized these restrictions, asserting that the belief China couldn’t develop AI chips was misguided. “The question is not whether China will have AI—it already does,” Huang said.

Southwest Airlines Tightens Portable Charger Rules Amid Rising In-Flight Fire Risks

Confusion is growing around airline policies on portable batteries, particularly power banks, due to rising concerns over fire hazards. Southwest Airlines has become the first major U.S. carrier to tighten its rules, now requiring passengers to keep chargers visible during use and forbidding their use in overhead bins. The shift follows a fire that destroyed an Air Busan plane in South Korea, though a definitive cause has yet to be established. Several Asian airlines—including EVA Air, China Airlines, Thai Airways, and Malaysia Airlines—have banned or limited power bank use and storage. Global policies vary, as there’s no industry-wide standard. Lithium-ion batteries pose a fire risk if damaged or overheated, with incidents on U.S. flights rising from 32 in 2016 to 84 in 2023. Portable chargers are the most frequent offenders. While in-flight battery fires are rarely fatal, crews are trained to respond quickly, often using containment bags or water to neutralize the danger. (New York Times)

Chinese paraglider survives accidental 8,000-metre-high flight above the clouds

Chinese paraglider Peng Yujiang survived an unintended ascent to over 8,000 meters after being caught in a powerful updraft in the Qilian Mountains. Starting at 3,000 meters, he was propelled to near Mount Everest’s height, enduring -35°C temperatures and briefly losing consciousness. His helmet camera captured the ordeal, which went viral online. Authorities deemed the flight accidental but penalized Peng with a six-month ban for not registering the flight. The incident highlights the risks of paragliding and the importance of adhering to safety regulations. (The Guardian)

The artistic movement that anticipated the algorithm

An exhibition at London’s Tate Modern, “Electric Dreams: Art and Technology Before the Internet,” explores the 1960s movement where artists and engineers collaborated to integrate technology into art. Initiatives like Experiments in Art and Technology (E.A.T.) saw figures like Robert Rauschenberg and John Cage work with engineers to create innovative performances combining art and science. The exhibition showcases works from global movements, including Italy’s Arte Programmata and France’s Groupe de Recherche d’Art Visuel, emphasizing the historical interplay between creativity and technology. Curator Valentina Ravaglia notes the relevance of these collaborations in today’s discussions on AI and authorship in art. (EL PAÍS English)
