Solar energy is now so cost-effective that, in the sunniest countries, it costs as little as £0.02 to produce one unit of power, making it cheaper than electricity generated from coal, gas or wind, according to a new study from the University of Surrey.

In a study accepted for publication in Energy and Environment Materials, researchers from Surrey’s Advanced Technology Institute (ATI) argue that solar photovoltaic (PV) technology is now the key driver of the world’s transition to clean, renewable power.

Professor Ravi Silva, co-author of the study and Director of the ATI at the University of Surrey, said, “Even here in the U.K., a country that sits 50 degrees north of the equator, solar is the cheapest option for large-scale energy generation.

A team of scientists from the University of Chicago, the University of California Berkeley, Argonne National Laboratory, and Lawrence Berkeley National Laboratory has developed molecular qubits that bridge the gap between light and magnetism—and operate at the same frequencies as telecommunications technology. The advance, published today in Science, establishes a promising new building block for scalable quantum technologies that can integrate seamlessly with existing fiber-optic networks.

Because the new molecular qubits can interact at telecom-band frequencies, the work points toward future quantum networks—sometimes called the “quantum internet...

New research led by the University of Cambridge, in collaboration with Hong Kong University of Science and Technology (GZ) and Queen Mary University of London, could redefine how we interact with everyday tools and devices—thanks to a novel method for printing ultra-thin conductive microfibers.

Imagine fibers thinner than a human hair (nano- to micro-scale in diameter) that can be tuned on-demand to add sensing, energy conversion and electronic connectivity capabilities to objects of different shapes and surface textures (such as glass, plastic and leather)...

Could a simple blood test reveal how well someone is aging? A team of researchers led by Wolfram Weckwerth from the University of Vienna, Austria, and Nankai University, China, has combined advanced metabolomics with cutting-edge machine learning and a novel network modeling tool to uncover the key molecular processes underlying active aging.

Their study, published in npj Systems Biology and Applications, identifies aspartate as a dominant biomarker of physical fitness and maps the dynamic interactions that support healthier aging.

It has long been known that exercise protects mobility and lowers the risk of chronic disease...
