Published Giving particle detectors a boost



Researchers have tested the performance of a new device that boosts particle signals.
Published Peering into the tendrils of NGC 604 with NASA's Webb



The formation of stars and the chaotic environments they inhabit is one of the most well-studied, but also mystery-shrouded, areas of cosmic investigation. The intricacies of these processes are now being unveiled like never before by NASA's James Webb Space Telescope.
Published Design rules and synthesis of quantum memory candidates



In the quest to develop quantum computers and networks, there are many components that are fundamentally different than those used today. Like a modern computer, each of these components has different constraints. However, it is currently unclear what materials can be used to construct those components for the transmission and storage of quantum information.
Published Preventing magnet meltdowns before they can start



High-temperature superconductor magnets have the potential to lower the costs of operating particle accelerators and enable powerful new technologies like fusion reactors. But quenches -- the sudden, destructive events wherein a part of the material loses superconductivity -- are a major barrier to their deployment. Scientists have developed an approach to prevent quenches altogether, rather than simply trying to manage them after they occur.
Published Combined microscopy technique catches light-driven polymers in the act



Researchers have used tip-scan high-speed atomic force microscopy combined with an optical microscope to observe light-induced deformation of azo-polymer films. The process could be followed in real time, and the film patterns were found to change with the polarization of the light source. The observations will contribute to the use of azo-polymers in applications such as optical data storage, and the approach is expected to be useful across materials science and physical chemistry.
Published Pushing the boundary on ultralow frequency gravitational waves



A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, the heaviest objects in the universe.
Published Researchers develop new machine learning method for modeling of chemical reactions



Researchers have used machine learning to create a model that simulates reactive processes in organic materials and conditions.
Published Making quantum bits fly



Physicists are developing a method that could enable the stable exchange of information in quantum computers. In the leading role: photons that make quantum bits 'fly'.
Published Finding new physics in debris from colliding neutron stars



Neutron star mergers are a treasure trove for new physics signals, with implications for determining the true nature of dark matter, according to physicists.
Published Astronomers spot oldest 'dead' galaxy yet observed



A galaxy that suddenly stopped forming new stars more than 13 billion years ago has been observed by astronomers. Using the James Webb Space Telescope, astronomers have spotted a 'dead' galaxy when the universe was just 700 million years old, the oldest such galaxy ever observed.
Published Discovery tests theory on cooling of white dwarf stars



Open any astronomy textbook to the section on white dwarf stars and you'll likely learn that they are 'dead stars' that continuously cool down over time. Astronomers are challenging this theory after discovering a population of white dwarf stars that stopped cooling for more than eight billion years.
Published Using light to precisely control single-molecule devices



Researchers flip the switch at the nanoscale by applying light to induce bonding for single-molecule device switching.
Published New method measures the 3D position of individual atoms



Since more than a decade it has been possible for physicists to accurately measure the location of individual atoms to a precision of smaller than one thousandth of a millimeter using a special type of microscope. However, this method has so far only provided the x and y coordinates. Information on the vertical position of the atom -- i.e., the distance between the atom and the microscope objective -- is lacking. A new method has now been developed that can determine all three spatial coordinates of an atom with one single image.
Published Shortcut to Success: Toward fast and robust quantum control through accelerating adiabatic passage



Researchers achieved the acceleration of adiabatic evolution of a single spin qubit in gate-defined quantum dots. After the pulse optimization to suppress quasistatic noises, the spin flip fidelity can be as high as 97.5% in GaAs quantum dots. This work may be useful to achieve fast and high-fidelity quantum computing.
Published Space tourism? Cosmic radiation exposure



Space weather experts are urging regulators and space tourism innovators to work together to protect their passengers and crews from the risks of space weather radiation exposure.
Published Groundbreaking survey reveals secrets of planet birth around dozens of stars



A team of astronomers has shed new light on the fascinating and complex process of planet formation. The research brings together observations of more than 80 young stars that might have planets forming around them, providing astronomers with a wealth of data and unique insights into how planets arise in different regions of our galaxy.
Published One way to improve a fusion reaction: Use weaknesses as strengths



Scientists are embracing imperfection, using less-than-ideal magnetic fields to make the plasma more manageable.
Published What makes black holes grow and new stars form? Machine learning helps solve the mystery



It takes more than a galaxy merger to make a black hole grow and new stars form: machine learning shows cold gas is needed too to initiate rapid growth -- new research finds.
Published Juno spacecraft measures oxygen production on Jupiter's moon, Europa



NASA's Juno spacecraft has directly measured charged oxygen and hydrogen molecules from the atmosphere of one of Jupiter's largest moons, Europa. These observations provide key constraints on the potential oxygenation of its subsurface ocean.
Published Webb unlocks secrets of one of the most distant galaxies ever seen



Looking deeply into space and time, astronomers have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old.
