Looking for the perfect fold? It’s frustrating.

Researchers at Princeton University have developed a new type of origami that changes its shape and properties in response to external stimuli. By introducing elastic components, they can execute precise folding patterns not previously possible. This technology has potential applications in prosthetics, antennas, and other devices.

Can courts safeguard fairness in an AI age?

The use of AI in the criminal justice system raises concerns about fairness and transparency. Researchers advise for clear understanding of data used and procedure by judges to use guidance from AI systems. Explainable AI systems may help, but transparency doesn't have to mean understanding computer code.

Claims on baby food fail to stack up

A study by the University of Auckland found that more than 200 processed baby foods in New Zealand feature misleading marketing and nutrition claims. Many of these claims don't stack up when examining the ingredients, with some products containing small amounts of fruit or vegetables despite featuring images of them on packaging.

Potential molecular link between air pollutants and increased risk of Lewy body dementia revealed

A team of researchers found a possible molecular link between air pollution and an increased risk of developing Lewy body dementia. Exposure to fine particulate air pollution (PM2.5) triggered the formation of abnormal alpha-synuclein clumps in mice, similar to those found in patients with Lewy body dementia.

New radiotheranostic targets identified for diagnosis and treatment of endometrial cancer

Researchers have identified two molecular targets, HER2 and CD24, as promising candidates for new nuclear diagnostics and therapeutics for endometrial cancer. These targets may help clinicians identify patients likely to respond to targeted therapies, offering new hope for those with disseminated or recurrent disease.

Study maps the happiest and saddest national anthems from around the globe

A study by the University of Jyväskylä analyzed 176 national anthems, finding that those from equatorial countries tend to be more energetic while those from northern regions are more melancholic. The happiest anthems originate from Western Sahara and China, while the saddest can be found in Japan and Israel.

Intestinal surface cells pull rather than push

Cells on the intestinal surface are replaced every few days due to pulling forces that determine which cells are weakest and need to leave. Weakened cells are removed from the intestine due to disrupted tug-of-war behavior, leading to inflammation and disease.

Increasing potassium levels improve outcomes in patients at high risk of ventricular arrhythmia

The POTCAST trial found that increasing potassium levels to the high-normal range significantly reduced the risk of sustained ventricular tachycardia, ICD therapy, unplanned hospitalizations, and all-cause mortality. This benefit was observed across various subgroups, including those with ischemic heart disease and heart failure.
