Published On the track of elusive neutrinos
(via sciencedaily.com) Scientists have been able to show that the CRES method is suitable for determining the neutrino mass and has already set an upper limit for this fundamental quantity in a first measurement -- an important milestone has thus been reached.
Published Furthest ever detection of a galaxy's magnetic field
(via sciencedaily.com) Astronomers have detected the magnetic field of a galaxy so far away that its light has taken more than 11 billion years to reach us: we see it as it was when the Universe was just 2.5 billion years old. The result provides astronomers with vital clues about how the magnetic fields of galaxies like our own Milky Way came to be.
Published Vast bubble of galaxies discovered, given Hawaiian name
(via sciencedaily.com) Original source The immense bubble is 820 million light years from Earth and believed to be a fossil-like remnant of the birth of the universe.
Published Researchers use AI to find new magnetic materials without critical elements
(via sciencedaily.com) A team of scientists developed a new machine learning model for discovering critical-element-free permanent magnet materials based on the predicted Curie temperature of new material combinations.
Published Better cybersecurity with new material
(via sciencedaily.com) Digital information exchange can be safer, cheaper and more environmentally friendly with the help of a new type of random number generator for encryption. The researchers behind the study believe that the new technology paves the way for a new type of quantum communication.
Published Hot Jupiter blows its top
(via sciencedaily.com) The planet HAT-P-32b is losing so much of its atmospheric helium that the trailing gas tails are among the largest structures yet known any planet outside our solar system. Three-dimensional (3D) simulations helped model the flow of the planet's atmosphere. The scientists hope to widen their planet-observing net and survey 20 additional star systems to find more planets losing their atmosphere and learn about their evolution.
Published A system to keep cloud-based gamers in sync
(via sciencedaily.com) A new technique can synchronize media streams from different networks to multiple devices with less than 10 milliseconds of delay. The technique was demonstrated on cloud gaming, but could also be applied in AR/VR applications.
Published Webb reveals new structures within iconic supernova
(via sciencedaily.com) NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelengths ranging from gamma rays to radio for nearly 40 years, since its discovery in February of 1987. New observations by Webb's NIRCam (Near-Infrared Camera) provide a crucial clue to our understanding of how a supernova develops over time to shape its remnant.
Published New AI technology gives robot recognition skills a big lift
(via sciencedaily.com) The day when robots can cook dinner, clear the kitchen table and empty the dishwasher is still a long way off. First, robots need to be able to recognize the many items of different sizes, shapes and brands in our homes. A team has now made a significant advance toward that technology with a robotic system that uses artificial intelligence to help robots better identify and remember objects.
Published Scientists detect and validate the longest-period exoplanet found with TESS
(via sciencedaily.com) Scientists have detected and validated two of the longest-period exoplanets found by TESS to date. These long period large exoplanets orbit a K dwarf star and belong to a class of planets known as warm Jupiters, which have orbital periods of 10-200 days and are at least six times Earth's radius. This recent discovery offers exciting research opportunities for the future of finding long-period planets that resemble those in our own solar system.
Published New giant planet evidence of possible planetary collisions
(via sciencedaily.com) A Neptune-sized planet denser than steel has been discovered by an international team of astronomers, who believe its composition could be the result of a giant planetary clash.
Published Breathe! The shape-shifting ball that supports mental health
(via sciencedaily.com) A soft ball designed to support mental health by 'personifying' breath has been invented by a computer science student.
Published Unprecedented gamma-ray burst explained by long-lived jet
(via sciencedaily.com) While astrophysicists previously believed that only supernovae could generate long gamma-ray bursts (GRBs), a 2021 observation uncovered evidence that compact-object mergers also can generate the phenomenon. Now, a new simulation confirms and explains this finding. If the accretion disk around the black hole is massive, it launches a jet that lasts several seconds, matching the description of a long GRB from a merger.
Published Analog and digital: The best of both worlds in one energy-efficient system
(via sciencedaily.com) We live in an analog world of continuous information flow that is both processed and stored by our brains at the same time, but our devices process information digitally in the form of discrete binary code, breaking the information into little bits (or bites). Researchers have revealed a pioneering technology that combines the potential of continuous analog processing with the precision of digital devices. By seamlessly integrating ultra-thin, two-dimensional semiconductors with ferroelectric materials, the research unveils a novel way to improve energy efficiency and add new functionalities in computing. The new configuration merges traditional digital logic with brain-like analog operations.
Published Telescopes help unravel pulsar puzzle
(via sciencedaily.com) With a remarkable observational campaign that involved 12 telescopes both on the ground and in space, including three European Southern Observatory (ESO) facilities, astronomers have uncovered the strange behavior of a pulsar, a super-fast-spinning dead star. This mysterious object is known to switch between two brightness modes almost constantly, something that until now has been an enigma. But astronomers have now found that sudden ejections of matter from the pulsar over very short periods are responsible for the peculiar switches.
Published Neptune's disappearing clouds linked to the solar cycle
(via sciencedaily.com) Astronomers have uncovered a link between Neptune's shifting cloud abundance and the 11-year solar cycle, in which the waxing and waning of the Sun's entangled magnetic fields drives solar activity.
Published Sensors harnessing light give hope in rehabilitation
(via sciencedaily.com) A research team overcomes limitations of conventional strain sensors using computer vision integrated optical sensors.
Published Quantum discovery offers glimpse into other-worldly realm
(via sciencedaily.com) Original source Experiments promote a curious flipside of decaying monopoles: A reality where particle physics is quite literally turned on its head
Published Computer scientists use AI to accelerate computing speed by thousands of times
(via sciencedaily.com) A team of computer scientists recently unveiled a prize-winning Python profiler called Scalene. Programs written with Python are notoriously slow -- up to 60,000 times slower than code written in other programming languages -- and Scalene works to efficiently identify exactly where Python is lagging, allowing programmers to troubleshoot and streamline their code for higher performance.
Published Quantum computer unveils atomic dynamics of light-sensitive molecules
(via sciencedaily.com) Researchers have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecules can take to change between different configurations. The observation method makes use of a quantum simulator, developed from research in quantum computing, and offers an example of how advances in quantum computing are being used to investigate fundamental science.
