Physics of irregular objects on inclined planes probed

How gravity causes a perfectly spherical ball to roll down an inclined plane is part of elementary school physics canon. But the world is messier than a textbook. Scientists have sought to quantitatively describe the much more complex rolling physics of real-world objects. They have now combined theory, simulations, and experiments to understand what happens when an imperfect, spherical object is placed on an inclined plane.

The hidden spring in your step

Researchers reveal the way our legs adapt to fast movements. When people hop at high speeds, key muscle fibers in the calf shorten rather than lengthen as forces increase, which they call ‘negative stiffness.’ This counterintuitive process helps the leg become stiffer, allowing for faster motion. The findings could improve training, rehabilitation, and even the design of prosthetic limbs or robotic exoskeletons.

Physicists discover a copper-free high-temperature superconducting oxide

Engineers have designed and synthesized a groundbreaking new material — a copper-free superconducting oxide — capable of superconducting at approximately 40 Kelvin, or about minus 233 degrees Celsius, under ambient pressure.

Smartwatches may help control diabetes through exercise

Wearable mobile health technology could help people with Type 2 Diabetes (T2D) to stick to exercise regimes that help them to keep the condition under control, a new study reveals. An international team studied the behavior of recently-diagnosed T2D patients in Canada and the UK as they followed a home-based physical activity program, with some participants wearing a smartwatch paired with a health app on their smartphone.

A lighter, smarter magnetoreceptive electronic skin

Imagine navigating a virtual reality with contact lenses or operating your smartphone under water: This and more could soon be a reality thanks to innovative e-skins. A research team has developed an electronic skin that detects and precisely tracks magnetic fields with a single global sensor. This artificial skin is not only light, transparent and permeable, but also mimics the interactions of real skin and the brain.

AI is as good as pathologists at diagnosing Celiac disease, study finds

A machine learning algorithm was able to correctly identify in 97 cases out of 100 whether or not an individual had Celiac disease based on their biopsy, new research has shown. The AI tool, which has been trained on almost 3,400 scanned biopsies from four hospitals, could speed up diagnosis of the condition and take pressure off stretched healthcare resources, as well as improving diagnosis in developing nations, where shortages of pathologists are severe.

Is AI the new research scientist? Not so, according to a human-led study

Researchers asked generative AI to write a research paper. While adept at some steps, it wholly failed at others.
