Using peptides and a snippet of the large molecules in plastics, materials scientists have developed materials made of tiny, flexible nano-sized ribbons that can be charged just like a battery to store energy or record digital information.

Researchers recently developed electronic tongue capable of identifying differences in similar liquids, such as milk with varying water content; diverse products, including soda types and coffee blends; signs of spoilage in fruit juices; and instances of food safety concerns. They found that results were even more accurate when artificial intelligence used its own assessment parameters

A new article shares findings from an extensive literature analysis of AI’s current trajectory in health care.

Researchers show that for the first time they have achieved atomic-scale observations of grain rotation in polycrystalline materials. Using state-of-the-art microscopy tools, the scientists were able to heat samples of platinum nanocrystalline thin films and observe the mechanism driving grain rotation in unprecedented detail.

A research team describes how they engineered an efficient new enzyme that can produce a synthetic genetic material called threose nucleic acid. The ability to synthesize artificial chains of TNA, which is inherently more stable than DNA, advances the discovery of potentially more powerful, precise therapeutic options to treat cancer and autoimmune, metabolic and infectious

NASA’s Curiosity rover, currently exploring Gale crater on Mars, is providing new details about how the ancient Martian climate went from potentially suitable for life — with evidence for widespread liquid water on the surface — to a surface that is inhospitable to terrestrial life as we know it.

Using ammonia is regarded as a promising method of transporting hydrogen. However, an efficient process is also needed to convert it back into hydrogen and nitrogen.

Researchers have developed a novel method of 3D printing that uses acoustic holograms. The process is called holographic direct sound printing (HDSP). It builds on a method introduced in 2022 that described how sonochemical reactions in microscopic cavitations regions — tiny bubbles — create extremely high temperatures and pressure for trillionths of a second to

A cognitive behavioral therapy (CBT) app has been found to significantly prevent increases in depression in young people who are at high risk — and could be implemented as a cost effective public mental health measure.

Engineers built a solar-powered desalination system that produces large quantities of clean water despite variations in sunlight throughout the day. Because it requires no extra batteries, it offers a much more affordable way to produce drinking water, compared to other solar-driven designs.
