Vaccine Hesitancy Persists Among Pregnant Women and Parents of Young Children

A new survey shows that most U.S. pregnant women and parents of young children do not plan to accept all recommended childhood vaccines. Only 38% of pregnant women and 34% of parents of children under two intend to follow the full vaccination schedule. The COVID-19 pandemic has likely worsened vaccine hesitancy, with fewer people trusting medical authorities. Parents cite concerns about vaccine safety and necessity, particularly for newer or less familiar vaccines like COVID-19 and flu. Pediatricians remain the most trusted source of information, suggesting a potential avenue to counter hesitancy. The findings highlight the growing need for targeted education and outreach to maintain herd immunity and protect public health. (CIDRAP)

Brain Awakening Follows a Predictable Front-to-Back Pattern

A new study of over 1,000 awakenings reveals that the brain reactivates in a specific order when transitioning from sleep to alertness. Researchers found that during REM sleep, brain activity begins in the front—responsible for executive function—then spreads backward, ending in visual regions. This front-to-back wave is consistent and differs from the more gradual and disorganized process of falling asleep. Using 256 scalp sensors, scientists tracked brain activity in 20 people and found similar patterns even when waking from non-REM sleep, though these began in a central hotspot. Participants felt groggier after REM sleep awakenings. The findings may help treat sleep disorders by targeting the waking process rather than just sleep onset. The study redefines waking as a distinct, ordered neural event. (Nature)

Health Insurers Are Quietly Rejecting More Drug Claims Than Ever

Health insurers are increasingly denying coverage for prescription drugs, often without explanation, leaving patients to face high out-of-pocket costs or abandon treatment. The rate of rejected pharmacy claims has surged, particularly for complex or expensive medications. Patients and doctors report confusing denial notices and long appeals processes. Critics argue that insurers are exploiting opaque systems and automated tools to reduce costs at the expense of care. Insurers claim denials are based on safety, efficacy, or policy terms, but the lack of transparency has raised alarms. The practice affects not just rare drug requests but also routine medications, creating barriers to adherence and potentially worsening health outcomes for millions of insured Americans.

Study Finds Hearing Loss, Loneliness Fuel Memory Decline

A large European cohort study from the University of Geneva has unveiled a significant link between hearing loss, social isolation, and memory decline in older adults. Participants with untreated hearing impairment who also experienced chronic loneliness displayed accelerated cognitive deterioration compared to peers. These findings highlight an urgent need for integrative public health strategies combining audiological intervention and social engagement to mitigate dementia risks—potentially delaying or preventing age-related cognitive decline.

Europe Sets Ambitious Target to Double Research Spending by 2035

European policymakers are working on a proposal to double public research and development spending by 2035, building on the Horizon Europe framework. The plan, part of the EU’s upcoming strategy document, aims to boost innovation, address geopolitical shifts, and compete with U.S. and Chinese investments in science. If enacted, it would increase annual R&D spending from €100 billion to €200 billion, a significant financial and political undertaking. However, early drafts lack specifics on implementation, funding mechanisms, and enforcement. Observers warn that national-level commitment will be critical to achieving the goal. The plan also highlights a growing European consensus that global leadership in science and technology requires both collaboration and strategic investment. (Science)

Malware Developers Exploit GitHub to Evade Detection

Cybersecurity researchers have identified a malware-as-a-service operation using GitHub to host and distribute malicious payloads. The malware, known as ‘Latrodectus,’ uses JavaScript and other files stored on GitHub to avoid traditional security filters. By exploiting the trustworthiness of GitHub’s platform, the malware delivery system evades detection and simplifies deployment for bad actors. This marks a shift in tactics, as threat actors increasingly use legitimate cloud services for criminal purposes. GitHub has removed the offending repositories, but experts warn that such methods are likely to proliferate. The incident underscores the growing challenge of balancing platform openness with security, especially as malware-as-a-service continues to evolve with more sophisticated delivery models.

Netflix Debuts Generative AI in New Series El Eternauta

Netflix has incorporated generative AI into its production process for the first time with the series El Eternauta, using the technology to help create background images. The move has drawn criticism from some viewers and creators concerned about job displacement and artistic authenticity. Netflix stated the AI-assisted images were used to enhance efficiency and creativity, not to replace human artists. The project marks a growing trend in the entertainment industry where AI tools are integrated into workflows. Critics argue this may open the door to wider automation in creative sectors. El Eternauta, an adaptation of a classic Argentine sci-fi comic, now finds itself at the intersection of technological innovation and ongoing labor debates. (The Guardian)

Delta’s AI Pricing Raises Concerns About Future of Cheap Flights

Delta Airlines is facing criticism over its use of AI-driven pricing strategies, which some say could end the era of affordable flights. The AI system analyzes demand and willingness to pay, dynamically adjusting prices in ways critics call predatory. Unlike traditional pricing, AI allows for more granular exploitation of consumer data and behaviors. Experts warn this could deepen inequality in travel access and eliminate predictable fare structures. Delta argues the system enhances revenue management without targeting individuals unfairly. However, growing use of AI in airline pricing has prompted calls for regulatory oversight and consumer protections. The controversy highlights the tension between business optimization and ethical use of artificial intelligence in marketplaces. (Ars Technica)

Neanderthal Bone Study Reveals Culinary or Ritual Practices

New analysis of butchered Neanderthal bones from two sites in Israel, lying just 70 km apart, indicates contrasting bone-processing techniques. One site showed systematic marrow extraction and breakage patterns consistent with culinary use, while the other displayed markings suggestive of ritualistic or non-dietary processing. These subtle yet clear behavioral differences challenge assumptions of uniform Neanderthal culture, pointing to localized practices and social complexity in prehistoric human groups. (Science Daily)
