CDC REPORTS NEW HUMAN H5 AVIAN FLU CASE MISSOURI
On September 13, the CDC reported a new human H5 avian flu case in Missouri, revealing that a household contact experienced similar symptoms on the same day, while a healthcare worker had mild symptoms but tested negative. Genetic sequencing confirmed the virus’s neuraminidase as N1 and showed it closely resembles the US dairy cow H5N1 strain. Although not all viral genes were sequable due to limited sample material, two unique hemagglutinin (HA) mutations were identified, potentially impacting vaccine cross-reactivity. The simultaneous onset of symptoms among contacts suggests a common exposure rather than person-to-person transmission. The index patient, hospitalized with underlying conditions, presented with chest pain, nausea, and other flu-like symptoms, received antiviral treatment, and has since recovered. No links to animals or raw milk have been found. Experts highlight the mutations’ implications for vaccine effectiveness and receptor binding, indicating the need for further study. (CIDRAP)
OPENAI UNVEILS STRAWBERRY AI MODELS AMID SECURITY CHALLENGES
OpenAI recently launched its “Strawberry” AI models, o1-preview and o1-mini, designed with enhanced reasoning capabilities. Unlike previous models, o1 processes problems step-by-step, offering users a filtered chain-of-thought via the ChatGPT interface while keeping the raw reasoning hidden. Attempts by hackers and red-teamers to access the unfiltered thoughts through jailbreaks or prompt injections have prompted OpenAI to issue warning emails and threaten bans for users probing the model’s inner workings. Reports indicate some early, unconfirmed successes in accessing the raw chain-of-thought. OpenAI defends this approach, citing the need to monitor for manipulation and protect competitive advantage, though it acknowledges drawbacks like reduced transparency. The AI community, including researchers like Simon Willison, criticizes OpenAI’s tight control, arguing it hinders safety research and interpretability. Concerns also arise that hiding the raw reasoning limits community trust and impedes collaborative advancements in AI development. (Ars Technica)
JAPAN REACHES 95K CENTENARIANS AMID DEMOGRAPHIC CHALLENGES
Japan has reached a milestone with over 95,000 individuals aged 100 or older, nearly 90% of whom are women, according to government data released on Tuesday. As of September 1, there are 95,119 centenarians, an increase of 2,980 from the previous year, with 83,958 women and 11,161 men. Additionally, the number of people over 65 has surged to a record 36.25 million, making up 29.3% of Japan’s population and positioning the country at the top among 200 nations with significant elderly populations. Japan is home to the world’s oldest living person, Tomiko Itooka, aged 116, and the oldest man, Kiyotaka Mizuno, aged 110. Despite efforts to mitigate the demographic decline, Japan faces a worsening population crisis marked by rising medical and welfare costs and a shrinking labor force. The government is addressing these challenges by gradually extending the retirement age to 65 for all employers starting fiscal 2025, though significant demographic issues persist. (Japan Today)
AI REVOLUTIONIZES UNDERSTANDING OF VIRAL EVOLUTIONARY PATHWAYS
Artificial intelligence (AI) is revolutionizing the understanding of viral evolution by enabling scientists to reconstruct virus family trees more accurately. Utilizing tools like DeepMind’s AlphaFold and Meta’s ESMFold, researchers can predict protein structures at scale, revealing hidden evolutionary relationships that traditional genome comparisons often miss due to the rapid mutation rates of RNA viruses. In a recent study published in *Nature*, Joe Grove and his team applied a structure-based approach to flaviviruses, including hepatitis C, dengue, and Zika viruses. They generated over 33,000 protein structures from 458 species, uncovering unexpected connections such as similarities between hepatitis C and pestiviruses’ entry mechanisms. Additionally, the study discovered that some flaviviruses have acquired enzymes from bacteria, indicating significant genetic exchange. These AI-driven insights are reshaping our understanding of viral origins and evolution, suggesting that the evolutionary histories of many viruses and even some cellular organisms may need to be reevaluated with these advanced tools.(Nature)
CONSERVATION EFFORTS COMBAT WHITE-NOSE SYNDROME TO SAVE BATS
Giorgia Auteri, a biologist, witnessed the devastating effects of white-nose syndrome in Michigan’s Upper Peninsula in 2014, where a deadly fungus, Pseudogymnoascus destructans, decimated bat populations. Originating from Europe, the fungus wreaks havoc on North American bats, disrupting ecosystems by allowing insect populations to surge, which has been linked to increased human infant mortality due to higher pesticide use. Researchers like Auteri and Greg Turner have made strides in combating the disease by using polyethylene glycol 8000 to coat fungal spores in hibernacula, significantly reducing infections. Additionally, modifying hibernation sites to maintain cooler temperatures helps bats survive by slowing fungal growth and promoting deeper hibernation. Efforts also include enhancing summer food sources to boost bats’ fat reserves and installing bat boxes to support reproduction. Genetic studies reveal that survivors possess mutations aiding their resilience, offering hope for population recovery. Conservation initiatives continue to employ innovative strategies to protect and restore bat numbers, emphasizing community involvement and scientific advancements. (New York Times)
RESEARCHERS DISCOVER 8.7 MILLION YEAR OLD MARINE FOSSILS
Researchers have uncovered marine fossils dating back up to 8.7 million years beneath San Pedro High School in South Los Angeles. Between June 2022 and July 2024, two significant fossil sites were discovered: an 8.7-million-year-old Miocene bone bed and a 120,000-year-old Pleistocene shell bed. Among the findings are fossils of a saber-toothed salmon, a megalodon shark, an extinct dolphin species, and hundreds of small fish vertebrae. Geologist Richard Behl from California State University, Long Beach, explained that the Miocene fossils were embedded in diatomite, indicating a once-rich algae ecosystem that supported diverse marine life. Wayne Bischoff of Envicom Corporation highlighted the rarity of such comprehensive ecological evidence from nine million years ago. Assistant Curator Austin Hendy from the Natural History Museum of Los Angeles County noted the presence of a submarine channel and nearby volcanism. The fossils are now shared with various research and educational institutions, promising enhanced scientific study and community recognition. (The Guardian)
AUSTRALIAN WINE GROWERS SUFFER SEVERE FROST DAMAGE
Wine grape growers in Australia’s prominent regions—Barossa Valley, Clare Valley, and Riverland—are facing significant crop losses due to unseasonable frosts, with forecasts indicating continued cold weather. Recent temperatures have plunged to -4°C in Barossa and 1.5°C in Riverland after several cold nights, causing extensive damage despite frost mitigation efforts like frost fans. Adrian Hoffmann from Barossa reports severe losses, often exceeding 50%, forcing growers to cut back crops. In Riverland, Australia’s largest grape-growing area, Michael Stivahtaris has lost at least 20% of his harvest due to September frosts and low winter rainfall, which dropped to 50mm over three months against an annual average of 250-300mm. Clare Valley’s Marnie Roberts highlights that an early budburst has prolonged frost exposure, exacerbating damage. Growers are employing strategies such as slashing vines and using liquid nitrogen to protect crops, but continued frosts threaten not only grapes but also other agricultural products like almonds and stone fruits.

RESEARCH CHALLENGES EGYPTIAN ORIGIN OF HOUNDS JACKALS
New research published in the European Journal of Archaeology challenges the long-held belief that the ancient board game Hounds and Jackals originated in Egypt. Archaeologists discovered a version of the game board in Gobustan, Azerbaijan, dating back to the Middle Bronze Age, which may predate the earliest Egyptian examples from 2064–1952 BCE. This finding suggests an Asian origin for the game, previously thought to be exclusive to Egypt and surrounding regions. Hounds and Jackals, also known as Fifty-Eight Holes, features two parallel sets of 29 holes and uses sticks with jackal or dog heads, functioning as a two-person race game. Similar ancient board games, such as Senet, Mehen, and Nine Men’s Morris, have been found worldwide, highlighting their role in social interaction and cultural exchange. The rapid spread of Hounds and Jackals across diverse cultures underscores the game’s function as a social lubricant, facilitating connections beyond social boundaries. However, precise dating is needed to confirm the game’s true origin. (Ars Technica)
