Words as a Mirror: AI Reads Personality from Language

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.

Snake Cannibalism Emerges Independently at Least 11 Times, Study Finds

Snake Cannibalism Emerges Independently at Least 11 Times, Study Finds

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.

Midlife Cannabis Surge Triggers New Cardiovascular Health Concerns

Midlife Cannabis Surge Triggers New Cardiovascular Health Concerns

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.

Giant phantom jellyfish captured in stunning deep-sea footage

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.

Motivation, Not Frequency, Key in Porn Use and Sexual Health

Motivation, Not Frequency, Key in Porn Use and Sexual Health

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.

Two Years of Research Vanish After Turning Off ChatGPT Data Sharing

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.

Rude Prompts May Improve ChatGPT Accuracy, Study Finds

A Penn State study using ChatGPT-4o shows that increasingly rude prompts yielded higher accuracy (about 84.8% for very rude vs. 75.8% for very polite, with ~80.8% for very polite), challenging earlier work that politeness boosts performance. The researchers note that tiny prompt wording changes can drastically affect outputs and cautions against deploying hostile interfaces in real-world use, while acknowledging the findings are not a license to insult AI.

Young Dementia Patient Andre Yarham Dies at 24, Donates Brain to Science

Andre Yarham, a 24-year-old from Norfolk diagnosed with frontotemporal dementia, chose to donate his brain to science after his death to aid research and help prevent others from suffering similar fates. His condition rapidly worsened, leading to his death over Christmas, highlighting that dementia can affect young people and is a cruel disease with no cure.
