‘We’re up against forces that have all the money in the world’: Erin Brockovich on her bat
In 1993, she squeezed a $333m settlement from a Californian energy company in a scandal over contaminated water. Three decades later, she has a new target in her sights – and it’s globalWhen Erin Brockovich woke to find 30 emails from people from the same town, she realised somet

Solar storms leave their mark on cosmic rays that reach Earth
A new study has revealed an unexpected link between solar storms and the flux of high-energy cosmic rays arriving at Earth. The findings, made using one of the world's largest cosmic ray detectors, could open up a new way to probe the magnetic structures inside solar storms—and p
Cost to rewire Great Britain’s electricity network could reach £90bn in 2030s
Cost to rewire Great Britain’s electricity network could reach £90bn in 2030s
Energy system operator says sum needed to deliver clean power targets while meeting rising demand is up by 50%The cost of rewiring Great Britain’s electricity networks through the 2030s is now 50% higher than before the Labour government came to power, and could reach almost £90b
Scientists say creatine may help fight depression
Scientists say creatine may help fight depression
Creatine is best known as a muscle-building supplement, but scientists are now investigating whether it could also help treat depression by boosting the brain's energy supply. A new review examined five randomized clinical trials involving 238 participants and found mixed results

Reform UK chair of Welsh environment committee may ‘undermine scrutiny’, says thinktank
Climate campaigners question choice of James Evans for role given past criticism of green energy projectsUK politics live – latest updatesThe appointment of a Reform UK member of the Senedd Cymru as the chair of a key Welsh environmental committee could “undermine the hard graft
One‑step process generates high entropy alloy nanoparticles in milliseconds for catalyst c
A University at Buffalo-led team of researchers has developed a method for producing advanced nanoparticles that could accelerate the discovery of new materials for energy and electronic applications. The study, published in Nature Communications, introduces a one-step process th

Abundant catalyst converts methane into valuable liquid chemicals
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and their collaborators have demonstrated a promising new approach for converting methane—the primary component of natural gas—into liquid chemicals that are precursors for many industrial chemical

While many of life's mysteries remain unsolved, every biologist can describe the basic processes performed by a living organism, including energy use, reproduction, growth and development. While these characteristics can be replicated in isolation in a lab, the idea of a complete
Acceptor molecule upconverts low-energy green light to high-energy purple with high effici
Solar cells and photocatalysts can be surprisingly inefficient. Despite light consisting of many wavelengths, the range that even highly efficient devices use is limited. Other wavelengths, especially long wavelengths, simply pass through the material without being used as energy

Cosmic dust could play key role in cracking long-standing mystery of solar corona heating
A researcher at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has published a new study in The Astrophysical Journal suggesting that tiny charged dust grains near the sun may significantly influence how energy moves through the solar c
Huge, specially designed heat pump saves a Norwegian agricultural cooperative millions
Huge, specially designed heat pump saves a Norwegian agricultural cooperative millions
There are some magical limits to how much energy we can get out of a heat pump. This story is about pushing the technical limits. It is about getting more energy out than you put in. And it's about how SINTEF—one of Europe's largest applied research organizations—the renewable en
Scientists create quantum sound device that could transform communications
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
