Published Utilizing active microparticles for artificial intelligence



Artificial intelligence using neural networks performs calculations digitally with the help of microelectronic chips. Physicists have now created a type of neural network that works not with electricity but with so-called active colloidal particles.The researchers describe how these microparticles can be used as a physical system for artificial intelligence and the prediction of time series.
Published Confirmation of ancient lake on Mars builds excitement for Perseverance rover's samples



Ground-penetrating radar on board NASA's Mars Perseverance rover has confirmed that the Jezero Crater, formed by an ancient meteor impact just north of the Martian equator, once harbored a vast lake and river delta. Over eons, sediment deposition and erosion within the crater shaped the geologic formations visible on the surface today. The discovery of lake sediments reinforces the hope that traces of life might be found in soil and rock samples collected by Perseverance.
Published Astronomers unravel mysteries of planet formation and evolution in distant planetary system



TOI-1136, a dwarf star located more than 270 light years from Earth, is host to six confirmed exoplanets and a seventh as yet unconfirmed candidate. The system has provided a rich source of information on planet formation and evolution in a young solar system. Researchers used a variety of tools to compile radial velocity and transit timing variation readings to derive highly precise measurements of the exoplants' masses, orbital information and atmospheres.
Published New method flips the script on topological physics



The branch of mathematics known as topology has become a cornerstone of modern physics thanks to the remarkable -- and above all reliable -- properties it can impart to a material or system. Unfortunately, identifying topological systems, or even designing new ones, is generally a tedious process that requires exactly matching the physical system to a mathematical model. Researchers have demonstrated a model-free method for identifying topology, enabling the discovery of new topological materials using a purely experimental approach.
Published Liquid lithium on the walls of a fusion device helps the plasma within maintain a hot edge



Emerging research suggests it may be easier to use fusion as a power source if liquid lithium is applied to the internal walls of the device housing the plasma. Past experiments studied solid lithium coatings and found they could enhance a plasma. The researchers were pleased they could yield similar results with liquid lithium, as it's better suited for use in a large-scale tokamak.
Published Shining a light on the hidden properties of quantum materials



Certain materials have desirable properties that are hidden and scientists can use light to uncover these properties. Researchers have used an advanced optical technique, based on terahertz time-domain spectroscopy, to learn more about a quantum material called Ta2NiSe5 (TNS).
Published Researchers add a 'twist' to classical material design



Researchers grew a twisted multilayer crystal structure for the first time and measured the structure's key properties. The twisted structure could help researchers develop next-generation materials for solar cells, quantum computers, lasers and other devices.
Published A new design improves water decontamination via plasma jet



Two research groups design a plasma (an ionized gas) reactor maintained by microwaves that makes it possible to decontaminate waters with high concentrations of dye.
Published What coffee with cream can teach us about quantum physics



A new advancement in theoretical physics could, one day, help engineers develop new kinds of computer chips that might store information for longer in very small objects.
Published Hacking DNA to make next-gen materials



Scientists have developed a universal method for producing a wide variety of designed metallic and semiconductor 3D nanostructures -- the potential base materials for next-generation semiconductor devices, neuromorphic computing, and advanced energy applications. The new method, which uses a 'hacked' form of DNA that instructs molecules to organize themselves into targeted 3D patterns, is the first of its kind to produce robust nanostructures from multiple material classes.
Published Atmospheric pressure changes could be driving Mars' elusive methane pulses



New research shows that atmospheric pressure fluctuations that pull gases up from underground could be responsible for releasing subsurface methane into Mars' atmosphere; knowing when and where to look for methane can help the Curiosity rover search for signs of life.
Published Gravity helps show strong force strength in the proton



New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force, a powerful mediator of particle interactions in the subatomic realm. The research has revealed, for the first time, a snapshot of the distribution of the shear strength of the strong force inside the proton -- or how strong an effort must be to overcome the strong force to move an object it holds in its grasp. At its peak, the nuclear physicists found that a force of over four metric tons would be required to overcome the binding power of the strong force.
Published Researchers find new multiphoton effect within quantum interference of light



An international team of researchers has disproved a previously held assumption about the impact of multiphoton components in interference effects of thermal fields (e.g. sunlight) and parametric single photons (generated in non-linear crystals).
Published Records of cometary dust hitting the asteroid Ryugu



The Hayabusa2 mission that collected samples from the asteroid Ryugu has provided a treasure trove of insights into our solar system. After analyzing samples further, a team of researchers have unearthed evidence that cometary organic matter was transported from space to the near-Earth region.
Published Manipulated hafnia paves the way for next-gen memory devices



A new study outlines progress toward making bulk ferroelectric and antiferroelectric hafnia available for use in a variety of applications, including high-performance computing.
Published Scientists advance affordable, sustainable solution for flat-panel displays and wearable tech



Scientists have developed 'supramolecular ink,' a new 3D-printable OLED (organic light-emitting diode) material made of inexpensive, Earth-abundant elements instead of costly scarce metals. The advance could enable more affordable and environmentally sustainable OLED flat-panel displays as well as 3D-printable wearable technologies and lighting.

Scientists have produced the first experimental evidence of vacuum decay.
Published DNA origami folded into tiny motor



Scientists have created a working nanoscale electomotor. The science team designed a turbine engineered from DNA that is powered by hydrodynamic flow inside a nanopore, a nanometer-sized hole in a membrane of solid-state silicon nitride. The tiny motor could help spark research into future applications such as building molecular factories or even medical probes of molecules inside the bloodstream.
Published Towards the quantum of sound



A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant move towards the ultimate goal of reaching the quantum ground state of sound in wave-guides. Unwanted noise generated by the acoustic waves at room temperature can be eliminated. This experimental approach both provides a deeper understanding of the transition from classical to quantum phenomena of sound and is relevant to quantum communication systems and future quantum technologies.
Published Moon rocks with unique dust found



A research team has for the first time discovered anomalous meter-sized rocks on the lunar surface that are covered in dust and presumably exhibit unique properties -- such as magnetic anomalies. These findings help to understand the processes that form and change the lunar crust.
