Structural blueprint for RNA therapeutics reveals why some siRNA molecules work better tha

RNA interference is a natural mechanism for living cells to control whether specific genes are being used. Crowned with the 2006 Nobel Prize in Physiology or Medicine, the discovery of RNA interference has since been harnessed by scientists to create a powerful and growing class

Disorder creates direction-dependent optics in compound semiconductors

An international research team has demonstrated that the intrinsic disorder of the compound semiconductor CuInSnS₄ can be exploited to influence its optical properties. While the atomic vibrations also sense the local disorder, their response is averaged over many different local

Why scientists fear we're missing evidence of extraterrestrial life

Scientists are raising concerns that we may be overlooking evidence of extraterrestrial life even when it is present. Hidden biosignatures, limitations in detection technology, and assumptions about what life should look like can all create dangerous false negatives. The research

New calculator reveals whether you should really worry about statin side effects

Scientists at the University of Oxford have created a calculator that predicts a person's individual risk of serious muscle disorders from statin medications. Their analysis found that more than 98% of people who qualify for statins are at low risk for these rare complications, d

A cataclysmic collision in space provides new clues on astronomy's biggest stalemate

Second only to black holes, neutron stars—incredibly dense star remnants—are the densest objects in the universe. When neutron stars collide, they create ripples in the fabric of space and time that we can detect on Earth.

AI-based demand forecasting creates planning reliability in the textile industry

How can sales figures be forecast more reliably, production capacities planned fully digitally, and employee know-how systematically integrated at the same time? To address this issue, Fraunhofer IWU developed an AI-powered demand forecasting tool for frottana Textil GmbH & Co. K

Scientists create quantum sound device that could transform communications

A new quantum device can generate precisely controlled bursts of sound-like particles, or phonons, by forcing electrons through an ultra-thin crystal at extremely low temperatures. The surprising behavior pushes beyond the limits predicted by current theories, suggesting scientis

Scientists reveal what really happens when water is trapped in tiny spaces

A decades-old puzzle about water has finally been unraveled. Researchers found that water trapped in tiny nanoscale spaces is not inherently more reactive. Instead, the intense pressures created inside these microscopic gaps explain most of the effect, while the surrounding mater

How asteroids may have sparked life on Earth

Ancient asteroid impacts may have done more than reshape Earth's surface—they could have helped spark life itself. New computer models show the collisions created enormous underground hydrothermal systems by cracking the planet's crust and allowing hot water to flow through it. T
