No Link Between Aluminum in Childhood Vaccines and Chronic Illnesses

A new review of over 100 studies finds no credible evidence that aluminum-containing adjuvants in childhood vaccines cause chronic illnesses such as asthma, autoimmune diseases, or diabetes. Researchers evaluated both animal and human data and found that aluminum exposure from vaccines is much lower than from food and environmental sources. The review also criticized past studies that linked vaccines to long-term conditions, citing weak methodologies and confounding factors. The findings support continued use of aluminum-adjuvanted vaccines, emphasizing their role in boosting immune responses safely. Experts conclude that the benefits of vaccines overwhelmingly outweigh any theoretical risks associated with aluminum exposure. (CIDRAP)

Cancer Breakthrough Supports Theory of Natural HIV Cure

New cancer immunotherapies are offering unexpected insights into HIV remission. A patient with both HIV and cancer received a stem cell transplant from a donor with a rare HIV-resistant mutation (CCR5-delta32). Notably, this patient stopped antiretroviral therapy and remained free of detectable virus for years, raising hopes for a functional cure. The case builds on previous examples of HIV remission after similar transplants, strengthening the hypothesis that eliminating HIV reservoirs is key. While such procedures are too risky for routine HIV treatment, they validate research into less invasive gene-editing approaches and immune-modulating therapies. Scientists now have more reason to believe that natural or engineered HIV cures are biologically feasible. (Science)

Experts found that Grok’s training data included extensive input from Musk’s social media posts, raising questions about objectivity and content moderation. Some researchers are alarmed that the chatbot appears to amplify its creator’s views, suggesting potential bias embedded in its architecture. The case highlights broader issues with AI governance, transparency in training data, and the risk of building personalized echo chambers at scale. (Ars Technica)

Arizona Confirms Fatal Case of Pneumonic Plague

Health officials in Coconino County, Arizona, have confirmed the death of a resident from pneumonic plague, a rare but severe form of Yersinia pestis infection. The case marks the state’s first plague death since 2020. Authorities are working to identify the source and assess potential exposures, urging residents to take precautions around fleas and wild animals, especially rodents. Pneumonic plague, which affects the lungs, is more contagious and dangerous than the more common bubonic form. Officials stress that while the risk to the general public is low, early diagnosis and antibiotic treatment are critical. Public health campaigns are underway to raise awareness and prevent further spread. (CIDRAP)

AI Nudify Websites Profit from Nonconsensual Image Exploitation

Websites using AI to digitally undress women in photos—known as AI nudify tools—are making millions, sparking serious ethical, legal, and psychological concerns. These platforms exploit deep learning models to generate fake nudes, often from social media images, and charge users for access. Victims, primarily women, are rarely aware their images have been used, and legal systems have struggled to keep up with enforcement. The sites operate through crypto payments and offshore domains to avoid regulation. Critics argue this constitutes a form of digital sexual violence, with experts calling for urgent legislation and platform accountability. Some countries have begun pursuing prosecutions, but global regulation remains patchy. (Wired)
