Physicists developed simplified formulas to quantify quantum entanglement in strongly correlated electron systems. Their approach was applied to nanoscale materials, revealing unexpected quantum behaviors and identifying key quantities for the Kondo effect. These findings advance understanding of quantum technologies.

Originally described in the context of particles drifting through liquid, Levy walk has been found to accurately describe a very wide range of phenomena, from cold atom dynamics to swarming bacteria. And now, a new study has found Levy walk in the movements of competing groups of organisms: football teams.

Researchers are working on artificial muscles that can keep up with the real thing. They have now developed a method of producing the soft and elastic, yet powerful structures using 3D printing. One day, these could be used in medicine or robotics — and anywhere else where things need to move at the touch of

A new study presents a compelling new model for the formation of super-Earths and mini-Neptunes — planets that are 1 to 4 times the size of Earth and among the most common in our galaxy. Using advanced simulations, the researchers propose that these planets emerge from distinct rings of planetesimals, providing fresh insight into planetary

Researchers combine acoustic monitoring with a neural network to identify fish activity on coral reefs by sound. They trained the network to sort through the deluge of acoustic data automatically, analyzing audio recordings in real time. Their algorithm can match the accuracy of human experts in deciphering acoustical trends on a reef, but it can

A new study has introduced a powerful tool for analyzing satellite imagery of boreal forests (also known as ‘Taiga’ in North America), offering unprecedented insights into the health and dynamics of these crucial ecosystems.

Current methods to recycle plastics often use expensive catalysts, harsh conditions and produce toxic byproducts. New process converts PET plastic into monomer building blocks, which can be recycled into new PET products or upcycled into higher value materials. In experiments, method recovered 94% of monomers from PET in just four hours, without harmful byproducts.

Scientists have discovered ‘berkelocene,’ the first organometallic molecule to be characterized containing the heavy element berkelium. The breakthrough disrupts long-held theories about the chemistry of the elements that follow uranium in the periodic table.

Over 120 years ago, Henry Ernest Dudeney posed the famous dissection problem of transforming a triangle into a square by cutting it into as few pieces as possible. In a new study, researchers have finally proved that the original solution, which involves only four pieces, is optimal by using a new proof technique. This technique

Researchers show that Cartan’s First Structure Equation, which relates to edge and screw dislocations in crystal lattices, can be recast in the same form as a basic mathematical formula that governs the behavior of electric currents and magnetic fields. This work can help make new concepts more understandable by employing more familiar frameworks.
