COLORADO REPORTS SEVENTH H5N1 CASE AMONG WORKERS
In Colorado, a second poultry farm worker has tested presumptively positive for H5N1 bird flu, marking the state’s seventh human case this month. This follows a series of infections among poultry workers, with six cases reported from another farm in Weld County. The outbreak began with H5N1 in wild birds and has spread to dairy cows, affecting 168 herds in 13 states. Recent cases in Colorado highlight a concerning trend, with the virus now impacting poultry workers. The USDA confirmed the virus’s transmission from wild birds to dairy cows in March. Despite the uptick in cases, there is no evidence of human-to-human transmission, and the general public’s risk remains low. Most cases have been mild and treatable with antivirals. The precise route of the virus’s spread between dairy and poultry farms is still unclear, but high temperatures and challenges with protective gear may be contributing factors. (Ars Technia)
GAZA FACES NEW HEALTH CRISIS AMID POLIO THREAT
In Gaza, a new health crisis looms as the threat of paralytic polio emerges amid ongoing conflict. On July 16, Gaza’s Ministry of Health reported poliovirus detection in wastewater samples from Khan Younis and Deir al-Balah, signaling the virus’s circulation. Although no paralysis cases have been confirmed yet, the chaotic conditions could mean some are undetected. The virus, a vaccine-derived strain, thrives in unsanitary conditions prevalent in Gaza, where war has devastated infrastructure. With 70% of water and sanitation facilities damaged and severe overcrowding, the virus’s spread is exacerbated. The vaccine-derived poliovirus type 2, emerging from weakened vaccine strains, poses significant risks, especially given the disruption in immunization efforts. Efforts to combat the outbreak include an urgent call for improved sanitation and targeted vaccination campaigns. However, the ongoing conflict complicates these efforts, making a ceasefire critical for effective vaccination and containment. (Science)

LENACAPAVIR COULD DROP TO $40 ANNUALLY IF LICENSED
Lenacapavir, a drug hailed as “the closest we have ever been to an HIV vaccine,” could potentially be priced at just $40 annually—a stark contrast to its current cost of $42,250 for the first year. This lower price is feasible according to recent research. Currently marketed by Gilead as Sunlenca, lenacapavir is administered every six months and has shown 100% protection in trials with over 5,000 women in South Africa and Uganda. While it’s approved for treatment, its preventive use could be transformative. Experts suggest that producing a generic version could cost around $40 per year, assuming widespread use. Campaigners urge Gilead to permit generic licensing through the UN’s Medicines Patent Pool for low- and middle-income countries. Gilead has pledged to develop a strategy for global access but has not finalized plans. Ensuring low-cost access to all affected regions is critical for combating HIV effectively. (The Guardian)
KOBAYASHI PHARMACEUTICAL CHAIRMAN RESIGNS AMID HEALTH SCANDAL
The chairman and president of Kobayashi Pharmaceutical, a major Japanese dietary supplement company, resigned on July 23 amid a health scare involving their red yeast rice tablets, which are used to lower cholesterol. The company faces scrutiny following reports linking the supplements to dozens of deaths and kidney issues. An external report criticized Kobayashi Pharmaceutical for its inadequate response to consumer safety concerns. The company recalled three brands of the supplement in March after customers reported kidney problems. It was later discovered that a potentially toxic acid from the mould used in production might be responsible. The company had initially received serious health reports in January and February but delayed action, according to the report. New president Satoshi Yamane will lead the company as it addresses these issues, while outgoing president Akihiro Kobayashi remains involved in compensation matters. (Channel News Asia)
OXYGEN DISCOVERED IN PACIFIC OCEAN AT GREAT DEPTHS
At the bottom of the Pacific Ocean, scientists have discovered a surprising source of oxygen at depths where photosynthesis is impossible. This phenomenon was observed in the Clarion–Clipperton Zone, an area rich in polymetallic nodules—ancient, plum-sized formations. Researchers found that, contrary to expectations, the oxygen levels in enclosed microcosms on the sea floor increased over time. This was unexpected since there are no photosynthetic organisms at these depths. The nodules might be playing a role in this process by catalyzing the splitting of water molecules, which produces oxygen. While the exact mechanism remains unclear, the discovery suggests that polymetallic nodules could be acting as catalysts rather than batteries. The findings raise questions about how these processes might impact deep-sea ecosystems and have potential implications for understanding extraterrestrial life. Researchers urge caution with deep-sea mining, as disrupting these nodules could harm dependent marine life. (Nature)
AI CHATBOTS STRUGGLE WITH MATH DESPITE ADVANCED LANGUAGE SKILLS
In the past school year, one class of learners—artificially intelligent chatbots—has presented an intriguing puzzle. These AI systems, like OpenAI’s ChatGPT, excel in tasks such as writing and summarizing text but often struggle with math. Despite their advanced capabilities in natural language processing, chatbots are less reliable with arithmetic and complex calculations. Kristian Hammond from Northwestern University explains that chatbots were designed for language, not for mathematical accuracy. Unlike traditional computers programmed for precise calculations, these AI models use neural networks, learning from vast data rather than following rigid rules. Recent updates have improved chatbots’ math skills. For instance, GPT-4 now achieves about 64% accuracy on a problem database, up from 58% previously. However, AI’s occasional mathematical errors provide a teaching moment. High school teacher Kirk Schneider uses these inaccuracies to encourage critical thinking and skepticism among students, reinforcing that even AI can make mistakes and should not be trusted blindly.

AI INTEGRATION CAUSES TURMOIL IN VIDEO GAME INDUSTRY
In 2023, the video game industry faced significant upheaval as generative AI began to integrate into its processes. Activision Blizzard, the company behind the Call of Duty series, announced the use of AI tools like Midjourney and Stable Diffusion for concept art, causing anxiety among employees. AI’s promise to increase productivity also led to fears of job displacement. The industry, valued at nearly $200 billion, has seen massive layoffs, with around 21,500 positions cut in 2023 and 2024. As AI tools became more prevalent, many artists and developers faced increased pressure and job insecurity. Generative AI’s ability to produce 2D images has particularly impacted roles like concept art and graphic design. Some studios, like Riot Games and Blizzard, experimented with AI but faced mixed reactions. The rise of AI has also highlighted broader issues in the industry, such as undervalued art and outsourcing practices. While some companies use AI to cut costs, others are attempting to develop proprietary systems. The debate over AI’s role in game development continues, with many workers advocating for unionization and greater control over AI’s implementation to protect their livelihoods and ensure fair use.
