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

Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective excitations referred to as quasiparticles. One case in which this occurs is the quantum Hall effect, a phenomenon that emerges when electrons are confined to a ve

When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of biology because they are often produced by living microbes. However, scientists can be misled because certain geological processes can produce chemical signat

Ynys Enlli, Gwynedd: A stroll down this island’s one road provides clues to its past – and it has nothing to do with the 20,000 saints apparently buried hereIn 1938, the Welsh naturalist Ronald Lockley described Ynys Enlli (Bardsey Island) as a mountain “crudely cemented to a low

A planet with one side permanently roasting and the other frozen in endless darkness might still have a chance of supporting life. Researchers found that heat inside a tidally locked exoplanet could circulate in a stable, continuous loop, helping moderate temperatures in certain

Proving that one quantum measurement is more powerful than another has long been difficult. Physicists from Heinrich Heine University Düsseldorf, Lund University and the University of Innsbruck have now developed and demonstrated a simple technique to certify that a certain class

Many of the body's biggest flaws are the result of evolution building on old designs instead of starting over. Our spine, eyes, teeth, pelvis, and even certain nerves all reveal compromises that worked well enough for survival but still leave us prone to pain, injury, and disease

Researchers discovered that electricity can dramatically reshape how heat flows through certain ceramic materials, increasing heat conduction by almost threefold in a preferred direction. The unexpected result could lead to much more efficient cooling technologies and energy-savi

As the adoption of electric vehicles continues to grow, so does the need for the safe and permanent storage of battery materials and industrial chemical waste. Certain waste streams require disposal in what are known as Category IV landfills, which impose particularly stringent r

Midnight to 6am block on some apps is latest stage of Labour’s bid to protect young people from online harmsSixteen and 17-year-olds are to be encouraged to observe a midnight social media curfew, in the latest stage of Labour’s bid “to protect the next generation” from online ha

No film-maker shows more day-drinking than Hong, and this study of an actor returning from a career break is the same again – as mysteriously addictive as everIt will not surprise fans of the prolific lo-fi Korean master Hong Sang-soo that his new film in black-and-white – which

Exclusive: Move comes as allies of Andy Burnham work on proposals to take water companies into public controlMinisters are drawing up plans to set legally binding debt targets for England’s water companies as they look for ways to avoid another corporate failure such as Thames Water.Sources say Emma Reynolds, the environment secretary, is working on proposals that would force companies to keep their debt below certain levels for the first time or face legal punishment.
