Published Why can't robots outrun animals?
(via sciencedaily.com) Original source Robotics engineers have worked for decades and invested many millions of research dollars in attempts to create a robot that can walk or run as well as an animal. And yet, it remains the case that many animals are capable of feats that would be impossible for robots that exist today.
Published Computer game in school made students better at detecting fake news
(via sciencedaily.com) Original source A computer game helped upper secondary school students become better at distinguishing between reliable and misleading news.
Published Holographic displays offer a glimpse into an immersive future
(via sciencedaily.com) Original source Researchers have invented a new optical element that brings us one step closer to mixing the real and virtual worlds in an ordinary pair of eyeglasses using high-definition 3D holographic images.
Published Opening up the potential of thin-film electronics for flexible chip design
(via sciencedaily.com) Original source The mass production of conventional silicon chips relies on a successful business model with large 'semiconductor fabrication plants' or 'foundries'. New research by shows that this 'foundry' model can also be applied to the field of flexible, thin-film electronics.
Published Eruption of mega-magnetic star lights up nearby galaxy
(via sciencedaily.com) Original source While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays -- high-energy photons -- coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explosion but found none. An international team realized that the burst must have been an extra-galactic flare from a magnetar, a young neutron star with an exceptionally strong magnetic field.
Published This tiny chip can safeguard user data while enabling efficient computing on a smartphone
(via sciencedaily.com) Original source A new chip can efficiently accelerate machine-learning workloads on edge devices like smartphones while protecting sensitive user data from two common types of attacks -- side-channel attacks and bus-probing attacks.
Published Super Mario hackers' tricks could protect software from bugs
(via sciencedaily.com) Original source Video gamers who exploit glitches in games can help experts better understand buggy software, students suggest.
Published Toward unification of turbulence framework -- weak-to-strong transition discovered in turbulence
(via sciencedaily.com) Original source Astrophysicists have made a significant step toward solving the last puzzle in magnetohydrodynamic turbulence theory by observing the weak to strong transition in the space plasma turbulence surrounding Earth with newly developed multi-spacecraft analysis methods.
Published Giant galactic explosion exposes galaxy pollution in action
(via sciencedaily.com) Original source Astronomers have produced the first high-resolution map of a massive explosion in a nearby galaxy, providing important clues on how the space between galaxies is polluted with chemical elements.
Published 2D materials rotate light polarization
(via sciencedaily.com) Original source Physicists have shown that ultra-thin two-dimensional materials such as tungsten diselenide can rotate the polarization of visible light by several degrees at certain wavelengths under small magnetic fields suitable for use on chips.
Published AI and physics combine to reveal the 3D structure of a flare erupting around a black hole
(via sciencedaily.com) Original source Based on radio telescope data and models of black hole physics, a team has used neural networks to reconstruct a 3D image that shows how explosive flare-ups in the disk of gas around our supermassive black hole might look.
Published Accelerating the discovery of new materials via the ion-exchange method
(via sciencedaily.com) Original source Researchers have unveiled a new means of predicting how to synthesize new materials via the ion-exchange. Based on computer simulations, the method significantly reduces the time and energy required to explore for inorganic materials.
Published Teaching a computer to type like a human
(via sciencedaily.com) Original source A new typing model simulates the typing process instead of just predicting words.
Published Skyrmions move at record speeds: A step towards the computing of the future
(via sciencedaily.com) Original source Scientists have discovered that the magnetic nanobubbles known as skyrmions can be moved by electrical currents, attaining record speeds up to 900 m/s. Anticipated as future bits in computer memory, these nanobubbles offer enhanced avenues for information processing in electronic devices. Their tiny size provides great computing and information storage capacity, as well as low energy consumption. Until now, these nanobubbles moved no faster than 100 m/s, which is too slow for computing applications. However, thanks to the use of an antiferromagnetic material as medium, the scientists successfully had the skyrmions move 10 times faster than previously observed. These results offer new prospects for developing higher-performance and less energy-intensive computing devices.
Published How 3D printers can give robots a soft touch
(via sciencedaily.com) Original source Soft skin coverings and touch sensors have emerged as a promising feature for robots that are both safer and more intuitive for human interaction, but they are expensive and difficult to make. A recent study demonstrates that soft skin pads doubling as sensors made from thermoplastic urethane can be efficiently manufactured using 3D printers.
Published No gamma rays seen coming from nearby supernova
(via sciencedaily.com) Original source A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA's Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light those particles should produce.
Published Most massive stellar black hole in our galaxy found
(via sciencedaily.com) Original source Astronomers have identified the most massive stellar black hole yet discovered in the Milky Way galaxy. This black hole was spotted in data from the European Space Agency's Gaia mission because it imposes an odd 'wobbling' motion on the companion star orbiting it. Astronomers have verified the mass of the black hole, putting it at an impressive 33 times that of the Sun.
Published Millions of gamers advance biomedical research
(via sciencedaily.com) Original source 4.5 million gamers around the world have advanced medical science by helping to reconstruct microbial evolutionary histories using a minigame included inside the critically and commercially successful video game, Borderlands 3. Their playing has led to a significantly refined estimate of the relationships of microbes in the human gut. The results of this collaboration will both substantially advance our knowledge of the microbiome and improve on the AI programs that will be used to carry out this work in future.
