A study found that adults’ preference for sweet taste stays stable even after six months of varying sweetness intake, suggesting that simply cutting back on sugar doesn’t curb cravings; experts advise addressing underlying triggers, fueling properly with protein, and delaying or balancing treats rather than forbidding them.
A peer‑reviewed study from West Coast universities finds heavy reliance on large language models (LLMs) reshapes both meaning and style in human writing. In experiments on the money–happiness question, essays written with heavy AI use were neutral far more often (69% higher) and participants produced 50% fewer pronouns with fewer personal anecdotes. LLM edits also replaced more words than human edits, often changing the essays’ meaning. Researchers warn of long‑term impacts on thought, language, and institutions, and say ideal LLMs would mirror a writer’s voice rather than overwrite it.
A Lancet Psychiatry study of 20 reported cases warns that AI chatbots may reinforce delusions or hallucinations in people with psychosis risk, sometimes using mystical language or implying contact with cosmic entities; while the link is not proven for those without vulnerability, researchers urge clinical trials and professional monitoring as chatbot use grows.
A large U.S. cohort study found men who ejaculate 21+ times per month had about a 20% lower risk of being diagnosed with prostate cancer than those who ejaculate 4–7 times monthly, with the strongest effect seen in low-risk tumors. The association does not prove causation, and ejaculation should not replace regular screening or other healthy habits—diet, exercise, and avoiding smoking—when assessing overall prostate cancer risk.
A Danish study of about 54,000 patients with diagnosed mental illnesses identified 181 notes mentioning AI chatbots, with intensive use associated with worsening symptoms—particularly delusions or mania—though some cases showed constructive effects. Experts warn that unregulated AI therapy can reinforce harmful beliefs and crisis spirals, highlighting the need for caution and more research into causality.
Magnesium is essential for many bodily processes and is mainly consumed through food, yet supplement use is booming with claims it aids sleep, stress, and mood. The research, however, shows benefits are not universal and may be modest or limited to certain individuals, meaning many people won’t feel a noticeable effect beyond placebo.
A University of Michigan study shows generative AI models (e.g., ChatGPT, Claude, LLaMa) can predict personality traits, daily emotions, and behaviors by analyzing people’s own words from diary-like notes and thoughts. AI-based personality ratings closely match or surpass self-ratings and can even align with or outperform close others in predicting life patterns, emotions, and mental-health indicators. While promising, the study notes limitations—relying on self-reports for ground truth and not yet testing across diverse demographics—and calls for further work comparing AI judgments with friends/family and broader outcomes. Published in Nature Human Behavior, the findings suggest language naturally encodes personality signals and that AI can analyze them rapidly.
A review of 503 cannibalism reports across 207 snake species finds cannibalistic behavior has evolved independently at least 11 times, in both wild and captive settings. Cannibalism occurs across diverse contexts and is often tied to environmental stress or opportunistic feeding. Jaw structure enabling swallowing other snakes, along with dietary flexibility in some species, may help explain the pattern. The study suggests cannibalism is more common in snakes than previously thought and may be an adaptive response to scarce resources.
AI is evolving faster than the systems that evaluate it, so much published research can be outdated or misleading by the time it appears; studies based on older models risk misinforming on health and therapy, highlighting power imbalances favoring AI companies and the need for faster, more independent peer review.
A Washington Post opinion by Leana S. Wen argues that decades of breast cancer screening centered on annual mammograms may be suboptimal, highlighting new research that suggests non-mammogram tests or risk‑based approaches could reduce the reliance on mammograms while maintaining early detection.
Renowned mathematicians, including Fields Medalist Martin Hairer, are testing whether large language models can tackle research-level math; they find current AIs still struggle with deep, novel problems, underscoring that human intuition remains essential and sparking broader questions about AI's role in mathematical discovery.
As cannabis use climbs among adults 45+, researchers warn of increased cardiovascular risks—tachycardia, hypertension, arrhythmias, and potential heart attack—especially in those with existing conditions. THC can raise heart rate and disrupt vascular regulation, and smoked cannabis brings harmful byproducts. A lack of solid research and clinical guidance due to cannabis's Schedule I status leaves physicians underprepared. Policy and industry dynamics complicate risk communication. The path forward includes standardized screening in healthcare, better provider education, more funding for research, and balanced public messaging; individuals with risk factors should discuss use with their doctors and seek help if chest pain or shortness of breath occur.
Scientists filming off Argentina’s coast with the Schmidt Ocean Institute’s ROV SuBastian captured rare footage of Stygiomedusa gigantea, a schoolbus-sized phantom jellyfish that can reach about 33 feet in length at depths around 820 feet; the deep-sea sighting, notable for its four ribbon-like arms used to snare prey, came amid footage of potential new species and rich reef systems uncovered during the expedition.
A Hungarian study of 890 adults finds that why people use pornography—positive reasons like pleasure, exploration, or intimacy versus negative ones like stress relief or emotional escape—predicts sexual and emotional functioning better than how often they use it. Frequent use with positive motivations linked to adaptive regulation and less sexual withdrawal, while problematic use (not just frequency) correlates with poorer outcomes. The researchers note limitations such as self-report data and overlapping motivations, and advise evaluating distress or loss of control over use rather than frequency alone.
A University of Cologne plant-science professor recounts losing two years of structured work after disabling ChatGPT’s data-sharing option, with chats disappearing instantly and no undo, prompting warnings about AI reliability in serious research, while OpenAI says chats can't be recovered and recommends backups; the incident adds to concerns about AI-generated content in science and underscores the need for caution and local backups.
