Published Can you trust your quantum simulator?


Physicists have developed a protocol to verify the accuracy of quantum experiments.
Published Light-based tech could inspire Moon navigation and next-gen farming


Super-thin chips made from lithium niobate are set to overtake silicon chips in light-based technologies, with potential applications ranging from remote ripening-fruit detection on Earth to navigation on the Moon. They say the artificial crystal offers the platform of choice for these technologies due to its superior performance and recent advances in manufacturing capabilities.
Published The mechanism of cosmic magnetic fields explored in the laboratory


Recent research shows that magnetic fields can spontaneously emerge in a plasma if the plasma has a temperature anisotropy. This mechanism is known as the Weibel instability. This new research is the first to unambiguously observe the Weibel instability in the laboratory. It offers a possible solution to the problem of the origin of the microgauss-level magnetic fields that permeate the galaxies.
Published COVID calculations spur solution to old problem in computer science


A mathematician was keen to forecast the evolution of the COVID epidemic. Instead, he ended up solving a problem which had troubled computer scientists for decades.
Published Clinical trial results indicate low rate of adverse events associated with implanted brain computer interface


There were no safety events that required removal of the device, no infections of the brain or nervous system, and no adverse events resulting in permanently increased disability related to the investigational device.
Published Researchers measure size-luminosity relation of galaxies less than a billion years after Big Bang


A team has studied the relation between galaxy size and luminosity of some of the earliest galaxies in the universe taken by the James Webb Space Telescope, less than a billion years after the Big Bang.
Published Computers that power self-driving cars could be a huge driver of global carbon emissions



A new model quantifies emissions that will be generated by computers on fully autonomous vehicles. If self-driving cars are widely adopted, their emissions will rival those generated by all the data centers in the world today. Keeping emissions at or below those levels would require hardware efficiency to improve more rapidly than its current pace.
Published Screen-printing method can make wearable electronics less expensive



A new study demonstrates that electrodes can be made using just screen printing, creating a stretchable, durable circuit pattern that can be transferred to fabric and worn directly on human skin. Such wearable electronics can be used for health monitoring in hospitals or at home. Current commercial manufacturing of wearable electronics requires expensive processes involving clean rooms. While some use screen printing for parts of the process, this new method relies wholly on screen printing, which can make manufacturing flexible, wearable electronics much easier and less expensive.
Published NASA's Webb uncovers star formation in cluster's dusty ribbons


NGC 346, one of the most dynamic star-forming regions in nearby galaxies, is full of mystery. Now, it is less mysterious with new findings from NASA's James Webb Space Telescope.
Published Ultracool dwarf binary stars break records


Astrophysicists have discovered the tightest ultracool dwarf binary system ever observed. The two stars are so close that it takes them less than one Earth day to revolve around each other. In other words, each star's 'year' lasts just 20.5 hours.
Published Wide diversity of galaxies in the early universe


New data have revealed that the structures of galaxies in the early universe were much more diverse and mature than previously known. JWST's ability to see faint high redshift galaxies in sharper detail than Hubble allowed the team of researchers to resolve more features and see a wide mix of galaxies.
Published Scientists find pair of black holes dining together in nearby galaxy merger


While studying a nearby pair of merging galaxies scientists have discovered two supermassive black holes growing simultaneously near the center of the newly coalescing galaxy. These super-hungry giants are the closest together that scientists have ever observed in multiple wavelengths. What's more, the new research reveals that binary black holes and the galaxy mergers that create them may be surprisingly commonplace in the Universe.
Published Searching for the earliest galaxies in the universe


Astronomers have used data from NASA's James Webb Space Telescope (JWST) Early Release Observations and discovered 87 galaxies that could be the earliest known galaxies in the universe. The finding moves the astronomers one step closer to finding out when galaxies first appeared in the universe -- about 200-400 million years after the Big Bang.
Published NASA's Webb Telescope reveals links between galaxies near and far


A new analysis of distant galaxies imaged by NASA's James Webb Space Telescope shows that they are extremely young and share some remarkable similarities to 'green peas,' a rare class of small galaxies in our cosmic backyard.
Published James Webb telescope reveals Milky Way-like galaxies in young universe


New images from NASA's James Webb Space Telescope (JWST) reveal galaxies with stellar bars -- elongated features of stars stretching from the centers of galaxies into their outer disks -- at a time when the universe was a mere 25% of its present age. The finding of so-called barred galaxies, similar to our Milky Way, this early in the universe will require astrophysicists to refine their theories of galaxy evolution.
Published Hubble finds that ghost light among galaxies stretches far back in time


In giant clusters of hundreds or thousands of galaxies, innumerable stars wander among the galaxies like lost souls, emitting a ghostly haze of light. These stars are not gravitationally tied to any one galaxy in a cluster. The nagging question for astronomers has been: how did the stars get so scattered throughout the cluster in the first place? Several competing theories include the possibility that the stars were stripped out of a cluster's galaxies, or they were tossed around after mergers of galaxies, or they were present early in a cluster's formative years many billions of years ago.
Published Measuring gamma-ray bursts' hidden energy unearths clues to the evolution of the universe


When stars die out, they emit gamma-ray bursts. Although scientist can calculate the explosion energy from dying stars, it is difficult to do when the conversion efficiency is low or unknown. Using light polarization, a research group has found a workaround for this, enabling astronomers to calculate the hidden energy of gamma-ray bursts.
Published Webb Space Telescope reveals previously shrouded newborn stars


Astronomers took a 'deep dive' into one of the first images from NASA's James Webb Space Telescope and were rewarded with a surprising discovery: telltale signs of two dozen previously unseen young stars about 7,500 light years from Earth.
Published Light from outside our galaxy brighter than expected


Scientists analyzed new measurements showing that the light emitted by stars outside our galaxy is two to three times brighter than the light from known populations of galaxies, challenging assumptions about the number and environment of stars are in the universe.
Published Exquisite views of distant galaxies



For decades, the Hubble Space Telescope provided us with the most spectacular images of galaxies. This all changed when the James Webb Space Telescope (JWST) launched and successfully completed commissioning. For astronomers, the universe is now revealed in a new way never imagined by the telescope's Near-Infrared Camera (NIRCam) instrument.
