Phys.org / X-ray four-wave mixing captures elusive electron interactions inside atoms and molecules
Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how electrons dance together. The technique, known as X-ray four-wave mixing, opens a new way to see ...
Phys.org / Wormholes may not exist—we've found they reveal something deeper about time and the universe
Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen.
Phys.org / Construction emissions are higher than thought—but the solution isn't building less, new study finds
Many cities are making great strides in the fight against climate change, such as improving building energy efficiency, reducing traffic congestion and switching to renewable power sources. But there is another often overlooked ...
Phys.org / Antarctic submillimeter telescope enables more complete view of the carbon cycle in star-forming regions
Chinese researchers have braved the cold and harsh environment of Antarctica in order to get a unique view of star formation in the interstellar medium (ISM). The Chinese National Antarctica and Arctic Research Expedition ...
Phys.org / Collapse of the Tang dynasty: Climate change likely played a role
Environmental phenomena and their consequences can disrupt social structures and destabilize political systems. An interdisciplinary research team demonstrated this using the example of the late Tang dynasty in medieval China.
Phys.org / Perovskite display technology demonstrates record efficiency and industry-level operational lifetime
A research team has developed a hierarchical-shell perovskite nanocrystal technology that simultaneously overcomes the long-standing instability of metal-halide perovskite emitters while achieving record-breaking quantum ...
Phys.org / New microscopy technique preserves the cell's natural conditions
Researchers at Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology) have developed an innovative microscopy technique capable of improving the observation of living cells. The study, published in Optics Letters, ...
Phys.org / Large parts of the tropics overlooked in environmental research, study says
Environmental research in the tropics is heavily skewed, according to a comprehensive study led by Umeå University. Humid lowland forest ecosystems receive a disproportionate amount of attention, while colder and drier regions ...
Phys.org / New spectroscopic method reveals ion's complex nuclear structure
Different atoms and ions possess characteristic energy levels. Like a fingerprint, they are unique for each species. Among them, the atomic ion 173Yb+ has attracted growing interest because of its particularly rich energy ...
Phys.org / Hidden magma oceans could shield rocky exoplanets from harmful radiation
Deep beneath the surface of distant exoplanets known as super-Earths, oceans of molten rock may be doing something extraordinary: powering magnetic fields strong enough to shield entire planets from dangerous cosmic radiation ...
Phys.org / Do-it-yourself ammonia production: Renewable-powered system uses calcium to reduce emissions and scale for farmers
The last time you scrubbed a streaky window or polished a porcelain appliance, you probably used a chemical called ammonia.
Phys.org / Comprehensive map reveals how E3 ligases organize protein cleanup in human cells
Maintaining cellular order is a major logistical challenge: Individual mammalian cells contain billions of protein molecules, which must be synthesized, deployed, and removed with precision. In the ubiquitin-proteasome system ...
