DNA-nanoparticle motors are exactly as they sound: tiny artificial motors that use the structures of DNA and RNA to propel motion by enzymatic RNA degradation. Essentially, chemical energy is converted into mechanical motion by biasing the Brownian motion. The DNA-nanoparticle motor uses the 'burnt-bridge' Brownian ratchet mechanism. In this type of movement, the motor is being propelled by the degradation (or 'burning') of the bonds (or 'bridges') it crosses along... Read more ›

A new study has identified a group of neurons that, when activated, can induce a hypometabolic state, akin to hibernation. The discovery could have far-reaching implications for conditions like obesity, cardiometabolic diseases, and even for space travel. The research team found that these neurons regulate key aspects of the brain-heart-gut axis. Read more ›

The ability to alter proteins to refine control over binding affinity and specificity can create tailored therapeutics with reduced side effects, highly sensitive diagnostic tools, efficient biocatalysis, targeted drug delivery systems and sustainable bioremediation solutions. However, various approaches to such protein redesign have time-consuming drawbacks. Researchers now offer a simplified method they call ProteinReDiff that uses artificial intelligence to speed the redesign of ligand-binding proteins. Read more ›

Scientists are unlocking the secrets of halide perovskites -- a material that's poised to reshape our future by bringing us closer to a new age of energy-efficient optoelectronics. Two physics professors are studying the material at the nanoscale: a place where objects are invisible to the naked eye. At this level, the extraordinary properties of halide perovskites come to life, thanks to the material's unique structure of ultra-thin crystals --... Read more ›

Experiments have yielded a fascinating new type of matter, neither granular nor crystalline, that responds to some stresses as a fluid would and to others like a solid. The new material, known as PAM (for polycatenated architected materials) could have uses in areas ranging from helmets and other protective gear to biomedical devices and robotics. Read more ›

Do speakers of different languages build sentence structure in the same way? In a neuroimaging study, scientists recorded the brain activity of participants listening to Dutch stories. In contrast to English, sentence processing in Dutch was based on a strategy for predicting what comes next rather than a 'wait-and-see' approach, showing that strategies may differ across languages.

Fast radio bursts are mysterious and brief flashes of radio emissions that were thought to be produced by magnetars, highly magnetized rotating neutron stars. Yet magnetars appear primarily in young star clusters. A repeating burst discovered last year has been pinpointed to the distant outskirts of an old but massive elliptical galaxy where, theoretically, such stars would long since have disappeared. Does this mean magnetars are not the source of... Read more ›

Following two months of record heat and precipitation in fall 2022, an estimated 7,500 lakes in West Greenland turned brown, began emitting carbon and decreased in water quality in less than a year. The spike in temperatures caused the precipitation to fall as rain instead of snow. The heat also caused permafrost to thaw, releasing an abundance of carbon, iron, magnesium and other elements that the rain washed into the... Read more ›

Antibiotic overuse is a key driver in the rise of antimicrobial resistance (AMR), a major global health crisis. Researchers have provided compelling evidence that short-course antibiotic treatments can be a game-changer in tackling ventilator-associated pneumonia (VAP), a serious infection common in critically ill patients.

Marine scientists highlights the complex interplay between heat stress, disease onset and coral mortality. They found that 66 percent of the colonies were bleached by February 2024 and 80 per cent by April. By July, 44 percent of the bleached colonies had died, with some coral genera, such as Acropora, experiencing a staggering 95 percent mortality rate. Read more ›
