For autonomous robots, not all rules are equal

A new rulebooks framework developed by Iowa State University researchers provides a principled way for autonomous systems to rank and reconcile competing goals. The framework avoids the issues of blending weighted trade-offs, allowing systems to clearly define which rules come first and choose the least harmful option.

GLP-1 drugs have long-term benefit for heart health

A new review found that GLP-1 weight-loss drugs significantly reduced the risk of heart attacks, strokes, and premature death. The treatment also lowered rates of non-fatal heart attacks, hospital admissions for heart failure, and deaths from any cause.

Health care costs reach a breaking point

The American Heart Association warns that healthcare affordability has reached crisis levels, with total spending approaching $5 trillion annually. The association proposes five guiding principles for action by lawmakers and policymakers to address the issue.

Cervical cancer: A growing gap between high- and low-income countries

A growing gap in cervical cancer incidence rates between high- and low-income countries threatens to escalate unless prevention efforts are increased. Researchers urge universal vaccination for girls and boys, as well as catch-up campaigns, to close the gap and prevent nearly 37 million cases of cancer by the end of the century.

Methamphetamine use linked to 1 in 6 heart attacks in California study

A new study published in the Journal of the American Heart Association found that methamphetamine use accounted for nearly 15% of heart attacks in a northern California study. People who suffered meth-related heart attacks were often young- to middle-aged men without traditional heart disease risk factors, highlighting the need for spe...

Severe narcolepsy found to damage a second brain region

Researchers found significant loss of neurons in the locus coeruleus, a second critical region involved in arousal and muscle tone regulation. This finding suggests an immune-mediated process and challenges the prevailing explanation for narcolepsy with cataplexy.

Liquid biopsy predicts response to breast cancer immunotherapy

A new liquid biopsy method has been developed to predict the response to immunotherapy in high-risk breast cancers. The study found that repeated blood sampling can assess and predict the evolving antitumor immune response to therapy, offering a potential tool for guiding immunotherapy decision-making.

GoPro HERO13 Black

GoPro HERO13 Black records stabilized 5.3K video for instrument deployments, field notes, and outreach, even in harsh weather and underwater conditions.

Nature loss brings catastrophic risks – new report

A new report highlights the catastrophic risks of nature loss on food systems, economies and societies. Chronic pressures like soil degradation and water scarcity are already reducing crop yields and increasing food prices.

UBCO breakthrough could transform future wireless networks

Researchers at UBC Okanagan have made a groundbreaking discovery in wireless communication by developing nonlinear intelligent surfaces that can process electromagnetic waves more efficiently. These surfaces mimic neurons in computerized neural networks, enabling complex signal transformations and improved communication reliability.

SAMSUNG T9 Portable SSD 2TB

SAMSUNG T9 Portable SSD 2TB transfers large imagery and model outputs quickly between field laptops, lab workstations, and secure archives.

Green hydrogen from just sun and water

A KIT spin-off has developed a photoreactor panel that generates hydrogen directly from sunlight and water, avoiding expensive electrolyzers. The technology offers a simpler, more scalable approach to green hydrogen production, making it suitable for local on-site use or large-scale solar projects.

Apple iPad Pro 11-inch (M4)

Apple iPad Pro 11-inch (M4) runs demanding GIS, imaging, and annotation workflows on the go for surveys, briefings, and lab notebooks.

Younger teens most at risk for inhalant use, new study finds

A new study from the University of Mississippi found that younger teens are most likely to try psychoactive inhalants like nitrous oxide. The study also linked inhalant use to certain behaviors such as smoking tobacco and getting into fights, with teenage girls having the highest odds of developing inhalant use disorder.

Evolution has reused the same genes for 120 million years, study shows

Scientists discovered that evolution used the same genes, ivory and optix, to evolve near-identical colour patterns among distantly related butterfly and moth species. This finding suggests that life on earth may be more predictable than first imagined, with nature following a particular route.

Medical AI moving faster than safety checks

Flinders University experts caution that AI's impressive capabilities do not automatically translate into safe use for patients. The researchers stress the need for strong governance and clearer standards for evaluation to ensure AI supports doctors in busy care settings.

How yeast find the perfect match

A mass mating event among yeast strains revealed specific preferences for partner selection. The study showed that yeast tend to choose partners that produce fitter offspring, with successful pairs exhibiting reduced genetic distance. This suggests an ancient and fundamental mechanism for mate choice in sexual reproduction.

Twisting water

The study reveals that the first four layers of water molecules possess a well-defined orientational structure with alternating molecular tilt and twist angles. This new understanding has important implications for processes at aqueous interfaces, including electrochemical devices such as batteries.

Can birth weight influence endurance limits?

A study published in Frontiers in Ecology and Evolution found that optimal birth weight for minimal kidney damage during extreme endurance events is around eight pounds. Individuals with lower or higher birth weights may face a greater risk of kidney stress or damage.

Caesarean birth: sex-specific effects on the microbiota

A study reveals that caesarean delivery alters microbial colonisation in the first days of life, with distinct effects on male and female mice. Males born by caesarean section develop increased susceptibility to colitis in adulthood, while females do not. This difference is linked to changes in gut microbiota and barrier function.
