Researchers break a fundamental rule to create a new concept: Heat that can be directed an

Normally, a material absorbs and emits heat in a linked way: A surface that absorbs heat well at a certain wavelength and direction will also emit heat in the same way. This fundamental relationship, known as reciprocity, limits the ability to independently control heat absorptio

New Horizons watches the solar wind as it slows down

Where does the solar system end and interstellar space begin? That's a question scientists have been working to answer using spacecraft traveling beyond the sun's influence. A team of researchers from the Southwest Research Institute, led by Heather Elliott, is using the Solar Wi

Pressure unlocks 3D superconductivity in tantalum disulfide at triple the temperature

Superconductors have long been considered a promising technology for the energy systems of the future. They can conduct electricity without resistance, thus eliminating both conduction losses and waste heat. Up to now, however, superconductors have only been applied in special ca

Incredible new material makes heat programmable

A newly developed material can control and "program" heat, allowing it to direct thermal radiation, switch modes, and remember its settings without continuous power. The innovation could lead to smarter infrared sensors, better energy technologies, and memory devices that use lig

Birdwatch: A yellowhammer cheer squad on my cycle around Suffolk

That characteristic song was an unexpected delight alongside the chiffchaffs, blackcaps and whitethroats tooWith hindsight, the late June heatwave was not the ideal time for my (very) old schoolmates and me to be cycling around Suffolk. Yet, despite the searing heat and the laten

UK museums at 'sharp end' of climate change challenge

As visitors peered at skeletons and preserved animals in a London zoological museum during a UK heat wave, staff focused on a different attraction: a computer screen glowing with red and green temperature indicators.

UK waters hit with extreme heatwave as global sea temperatures reach record levels

Experts warn that some marine species are at risk of ‘mass mortality events’ in ever-warming oceansUK waters are being hit with an “extreme” marine heatwave, the Met Office has said, as scientists warn that high ocean temperatures globally could result in “mass-mortality events”

Turning up the heat on cancer: Manganese ferrite nanoparticles outperform rivals

Scientists have long known that heat can be used to help fight cancer. But heating tumors and cancer cells is trickier than it sounds. Apply too much heat and patients could get hurt; apply too little or target the wrong location and the therapy will not be effective.

International team says science alone won't save coral reefs

Coral reefs are disappearing at an unprecedented rate as climate change, marine heat waves, pollution and coastal development threaten one of Earth's richest ecosystems. While scientific research has greatly advanced understanding of the crisis and ways to restore damaged reefs,

Could geoengineering work to tamp down super El Niños?

With an anticipated "super" El Niño looming, a new study led by UC San Diego's Scripps Institution of Oceanography considers whether society could use a weather-altering technique as a tool to mitigate the floods, extreme heat and other events that El Niño would bring. The findin
