CALIFORNIA SUES EXXONMOBIL FOR MISLEADING PLASTIC RECYCLING

California has initiated a landmark lawsuit against ExxonMobil, accusing the company of misleading the public for decades about the viability of plastic recycling. The lawsuit alleges that ExxonMobil was aware of the technical and economic challenges of recycling plastics and recognized its limited effectiveness in reducing environmental plastic waste. Despite this, the company promoted recycling as a solution, contributing to increased plastic usage and pollution. Attorney General Rob Bonta stated that ExxonMobil’s deception has led California to spend over $1 billion annually managing plastic waste. The lawsuit seeks the creation of an Exxon-funded abatement fund to support cleanup efforts and educate consumers on recyclable plastics. Additionally, it calls for ExxonMobil to cease deceptive communications regarding recycling. The legal action follows extensive investigations into the fossil fuel and petrochemical industries’ roles in exacerbating plastic pollution. Environmental experts view this as a crucial step in the global fight against plastic waste, highlighting the need for accountability and genuine solutions to the plastic crisis. (NPR)

CMA APOLOGIZES TO INDIGENOUS PEOPLES FOR MISCONDUCT

The Canadian Medical Association (CMA) recently issued a formal apology to Indigenous Peoples in Canada—First Nations, Inuit, and Métis—for its historical role in medical racism and research misconduct since 1867. During an emotional ceremony incorporating Indigenous song, dance, and saging, the CMA acknowledged harmful actions by physicians and medical students, recognizing the lasting impact on future generations. A detailed 47-page report highlighted unethical practices, including forced sterilizations, nutritional experiments on Indigenous children, and non-consensual medical procedures on adults. These abuses have contributed to significant health disparities, shorter life expectancies, and persistent mistrust of the medical system among Indigenous communities. The CMA’s apology concludes a three-year reconciliation effort involving extensive research and consultations with Indigenous leaders. Moving forward, the CMA commits to actions such as increasing Indigenous representation in medicine and revising ethical guidelines. Leaders hope this apology will inspire broader reconciliation efforts and improve healthcare relationships with Indigenous Peoples. (Science)

EXTENSIVELY DRUG-RESISTANT TYPHOID SPREADS IN PAKISTAN

Eight-year-old Ukasha and his classmate AbuZar from a village near Peshawar, Pakistan, suffered prolonged typhoid fever due to an extensively drug-resistant (XDR) strain of Salmonella typhi. Normally treatable with antibiotics, XDR-typhoid resists most medications, leading to higher mortality rates and limited treatment options like the costly last-resort drug meropenem. Pakistan reports over 15,000 XDR-typhoid cases, exacerbated by poor water sanitation and widespread antibiotic overuse. Contaminated water sources, such as a suspected school water tank, fuel the outbreak, while inadequate hygiene practices and limited healthcare access worsen the situation. Despite vaccinating over 30 million children since 2019, the infection continues to spread, now reaching northern regions. Globally, XDR-typhoid cases have emerged in 16 countries, prompting the US CDC to warn travelers and world leaders to address the crisis at the UN. Experts warn that without effective intervention, typhoid could become deadly again. (The Guardian)

INDONESIA FORMS NEW CYBER FORCE AS MILITARY BRANCH

Indonesian Presidents Joko Widodo and President-elect Prabowo Subianto have approved the creation of a new Cyber Force, the fourth branch of the Indonesian Military (TNI). This unit aims to effectively counter foreign cyber attacks and will operate alongside the Army, Navy, and Air Force, becoming a priority in Prabowo’s incoming Cabinet. Coordinating Minister Hadi Tjahjanto emphasized the critical role of cyber warfare in modern conflicts, citing a major June cyber attack that disrupted over 40 government agencies. The Cyber Force will handle psychological operations, conduct daily cyber patrols, and implement security measures. While Prabowo supports the initiative, officials like Deputy Speaker Lodewijk Freidrich Paulus warned that without adequate funding and advanced defense equipment, the force would be ineffective. He stressed the necessity of investing in sophisticated cyber technology and satellite systems to prevent Indonesia from lagging behind other nations such as China, Germany, Norway, and Singapore. The establishment of the Cyber Force marks a significant step in Indonesia’s efforts to enhance its cybersecurity capabilities. (Channel News Asia)

JAPANESE RESEARCHERS CREATE SELF-COOLING LIGHT-EMITTING MATERIAL

Researchers at Chiba University and Osaka University, led by Professor Yamada Yasuhiro, have developed a groundbreaking material that cools itself by emitting light. Unlike the glowing robots and weapons seen in anime and video games, this real-life application uses crystals composed of cesium, lead, and bromine in perovskite structures. When exposed to specific light wavelengths, the material absorbs and then re-emits a stronger light, effectively releasing heat and lowering its temperature by 10°C in ten minutes. This self-cooling mechanism offers significant advantages over traditional methods like Peltier plates, especially in environments like space where conventional heat transfer is ineffective. The material’s ability to convert heat into visible light opens possibilities for cooling spacecraft and advanced electronics. Despite its potential, the use of toxic elements such as cesium, lead, and bromine poses challenges. Nevertheless, the innovation has excited sci-fi enthusiasts and holds promise for future technological advancements in cooling solutions. (Japan Today)

NEANDERTHAL THORIN DISCOVERY CHANGES HUMAN EVOLUTION THEORY

Paleoanthropologist Ludovic Slimak made a significant discovery in 2015 at Grotte Mandrin, Rhône Valley, France, uncovering a Neanderthal jaw fragment. Over 17 years of excavation, Slimak and his team found multiple bones and teeth, identifying the Neanderthal, named Thorin after Tolkien’s last dwarf king, as having lived 42,000 years ago near the species’ extinction. Genetic analysis published in Cell Genomics revealed that Thorin’s lineage remained isolated from other Neanderthal groups despite nearby populations, showing high genetic homozygosity indicative of inbreeding and no interbreeding with contemporary modern humans. Slimak had long theorized that Rhône Valley Neanderthals differed from surrounding groups based on distinct stone tool styles. The findings challenge existing views on Neanderthal extinction, suggesting that isolated populations could survive for millennia without gene flow from other groups. This discovery prompts a reevaluation of human evolution and the factors leading to Homo sapiens becoming the sole surviving human species. (Popular Mechanics)

ENGINEERED HUMAN HEART TISSUES WEAKEN UNDER SPACE MICROGRAVITY

A study published in the Proceedings of the National Academy of Sciences found that engineered human heart tissue weakened, developed irregular beating patterns, and experienced molecular and genetic changes akin to aging after just one month in space. Led by biomedical engineer Deok-Ho Kim, researchers sent “heart-on-a-chip” systems—comprising human induced pluripotent stem cell-derived heart muscle cells—to the International Space Station (ISS) for 30 days. These tissues showed a nearly 50% reduction in contraction strength after 12 days and significant irregularities in beating by day 19, which normalized upon returning to Earth. Transmission electron microscopy revealed shorter, disordered sarcomeres and fragmented mitochondria, while RNA sequencing indicated increased expression of genes related to inflammation and heart disorders and decreased expression of genes essential for heart function. The findings suggest that microgravity induces reversible cardiovascular stress similar to aging. This innovative heart-on-a-chip approach provides a valuable tool for studying organ responses to spaceflight, with plans to extend research and develop drugs to counteract microgravity’s effects on the heart.

MAN TAKES RAPAMYCIN TO EXTEND HEALTHY LIFESPAN

In March, 69-year-old Robert Berger began taking weekly low-dose rapamycin to extend his “health span.” Originally used to suppress immune systems in organ transplant patients, rapamycin is now touted by scientists and longevity enthusiasts as a potential anti-aging drug. Prominent figures like Dr. Peter Attia advocate its benefits, supported by animal studies showing significant lifespan increases. However, human research remains limited and inconclusive, with few studies showing minor benefits such as improved gum health and increased energy, while others report no significant changes. Potential side effects include increased cholesterol and insulin resistance, raising safety concerns. Experts emphasize the need for long-term human trials to verify rapamycin’s efficacy and safety, as current evidence is primarily based on animal models. Despite excitement in the longevity community, medical professionals caution against widespread use until more comprehensive data is available, highlighting the drug’s risks versus uncertain benefits.
