Decoded rules of microRNA strand selection reveal conserved, programmable features‎

MicroRNAs, whose discovery was recognized with the 2025 Nobel Prize in Physiology or Medicine, are central regulators of gene expression, yet a fundamental question has remained unanswered: how cells choose between the two strands produced from each microRNA precursor.

Video: Why 'basic science' is the foundation of innovation‎

At first glance, some scientific research can seem, well, impractical. When physicists began exploring the strange, subatomic world of quantum mechanics a century ago, they weren't trying to build better medical tools or high-speed internet. They were simply curious about how the universe worked at its most fundamental level.

Early humans relied on simple stone tools for 300,000 years in a changing east African landscape‎

Our prehistoric human ancestors relied on deliberately modified and sharpened stone tools as early as 3.3 million years ago. The selection of rock type depended on how easily the material could be flaked to the desired shape and form.

Horses can smell human fear when we sweat‎

Horses can smell your fear. If you are experiencing this emotion while standing near a horse, they will be able to detect it through your scent alone, which changes their behavior and physiology. That's the conclusion of a new study published in the journal PLOS One.

The world's first room-temperature continuous-wave UV-B laser diode on a sapphire substrate‎

Ultraviolet-B (UV-B) semiconductor lasers are highly sought for medical, biotechnology, and precision manufacturing applications; however, previous UV-B laser diodes were limited to pulsed operation or required cryogenic cooling, making continuous room-temperature operation unattainable.
