Pauling's rules about crystal structures flunk test
Only 13 % of oxide crystal structures obey 4 of the 5 rules simultaneously
The force is strong in neutron stars
Physicists have for the first time characterized the strong nuclear force, and the interactions between protons and neutrons, at extremely short distances.
Using light to put a twist on electrons
Method with polarized light can create and measure nonsymmetrical states in a layered material.
Sweat sensor detects stress levels; May find use in space exploration
A researcher has developed a sweat sensor capable of monitoring levels of cortisol in the body.
Method with polarized light can create and measure nonsymmetrical states in a layered material
Some molecules, including most of the ones in living organisms, have shapes that can exist in two different mirror-image versions. The right- and left-handed versions can sometimes have different properties,...
Tadpoles break the tension with bubble-sucking
When it comes to the smallest of creatures, the hydrogen bonds that hold water molecules together to form 'surface tension' lend enough strength to support their mass: think of insects...
Explained: Why water droplets 'bounce off the walls'
Researchers can now explain why some water droplets bounce like a beach ball off surfaces, without ever actually touching them. Now the design and engineering of future droplet technologies can...
Tax rule for industry rewards carbon capture
When it comes to encouraging manufacturers to reduce their carbon dioxide (CO2) emissions, a carrot might be more effective than a stick. That's the approach taken by a recent U.S....
Explained: Why water droplets 'bounce off the walls'
University of Warwick researchers can now explain why some water droplets bounce like a beach ball off surfaces, without ever actually touching them. Now the design and engineering of future...
Watch: Knight-in-training takes epic quest in 'Letter for the King' trailer
"His Dark Materials" actor Amir Wilson stars in "The Letter for the King," a Netflix fantasy series based on the Tonke Dragt novel.
Isotope movement holds key to the power of fusion reactions
Fusion may be the future of clean energy. The same way the sun forces reactions between light elements, such as hydrogen, to produce heavy elements and heat energy, fusion on...
Motley crew: Rust and light a possible answer to the conundrum of hydrogen fuel production
In today's narrative of climate change, pollution, and diminishing resources, one fuel could be a game-changer within the energy industry: hydrogen. When burned in a combustion engine or in an...
The force is strong in neutron stars
Most ordinary matter is held together by an invisible subatomic glue known as the strong nuclear force — one of the four fundamental forces in nature, along with gravity, electromagnetism, and the weak...
Using light to put a twist on electrons
Some molecules, including most of the ones in living organisms, have shapes that can exist in two different mirror-image versions. The right- and left-handed versions can sometimes have different properties, such that only...
Perovskite solar cells made with peppermint oil and walnut aroma food additives, preventing lead leakage
Engineers have developed eco-friendly-solvent processable hole transport polymers by using peppermint oil and walnut aroma food additives and the polymer can prevent lead leakage.
Study identifies a transition in the strong nuclear force that illuminates the structure of a neutron star's core
Most ordinary matter is held together by an invisible subatomic glue known as the strong nuclear force—one of the four fundamental forces in nature, along with gravity, electromagnetism, and the...
Team develops separator that reduces gas crossover for water electrolyzer
Dr. Won-chul Cho of the Hydrogen Research Department of the Korea Institute of Energy Research (President Jong-nam Kim) has developed a separator membrane that significantly reduces gas crossover while exhibiting...
Glass slides that stand to revolutionize fluorescence microscopy
EPFL scientists have developed a new type of microscope slide that can boost the amount of light in fluorescence microscopy by a factor of up to 25. These new slides...
Small precipitates make big difference in mitigating strength-ductility tradeoff
Researchers from the Institute of Mechanics of the Chinese Academy of Sciences, teaming up with scientists from Singapore and the U.S., have found that nanoscale precipitates provide a unique sustainable...

Fusion may be the future of clean energy. The same way the sun forces reactions between light elements, such as hydrogen, to produce heavy elements and heat energy, fusion on...
Building ultrasensitive and ultrathin phototransistors and photonic synapses using hybrid superstructures
Organic-inorganic halide perovskite quantum dots (PQDs) form an attractive class of materials for optoelectronic applications. Their charge transport properties are, however, inferior compared to materials such as graphene. Conversely, graphene contains a charge generation...
Scientists 'film' a quantum measurement
Measuring a quantum system causes it to change—one of the strange but fundamental aspects of quantum mechanics. Researchers at Stockholm University have now been able to demonstrate how this change...
Metal-organic frameworks can separate gases despite the presence of water
Metal-organic frameworks (MOFs) are promising materials for inexpensive and less energy-intensive gas separation even in the presence of impurities such as water.
First shots with Fujifilm’s X-T4 Mirrorless camera
The Fujifilm X-T4 is X-built around a trans CMOS 4 sensor and X-Processor 4 for fast AF and a wide dynamic range. (Jeanette D. Moses/)Fujifilm just announced the arrival of the X-T4,...
Light-shrinking device enables detection of ultra-tiny substances
Engineers at the University of California San Diego and the University of California Berkeley have created light-based technology that can detect biological substances with a molecular mass more than two...
Separation chemistry: A step toward greener metal recycling processes
Liquid-to-liquid extraction is the basic process used in hydrometallurgy for recycling metals and decontaminating solvents (to recover molecules that can be re-used or to decontaminate them). Until now, the "recipes"...
