Published Quest for alien signals in the heart of the Milky Way takes off
(via sciencedaily.com) Original source A graduate student is spearheading an extraordinary scientific endeavor -- a groundbreaking mission to uncover periodic signals emanating from the core of the Milky Way called the Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS). Such repetitive patterns could be the key to unlocking the mysteries of extraterrestrial intelligence in our galaxy.
Published Towering plume of water escaping from Saturn moon
(via sciencedaily.com) Original source Scientists have observed a towering plume of water vapor more than 6,000 miles long -- roughly the distance from the U.S. to Japan -- spewing from the surface of Saturn's moon, Enceladus.
Published Source-shifting metastructures composed of only one resin for location camouflaging
(via sciencedaily.com) Original source Acoustic source-shifters make observers mis-perceive the location of sound by reproducing a sound emanating from a location different from the actual location of a sound source. Researchers have now developed a design approach to produce high-performance source-shifters using a common polymer for location camouflage. Utilizing inverse design based on topology optimization, this development could pave the way for advanced augmented reality and holography technology.
Published 107-million-year-old pterosaur bones: Oldest in Australia
(via sciencedaily.com) Original source A team of researchers have confirmed that 107-million-year-old pterosaur bones discovered more than 30 years ago are the oldest of their kind ever found in Australia, providing a rare glimpse into the life of these powerful, flying reptiles that lived among the dinosaurs.
Published Robot centipedes go for a walk
(via sciencedaily.com) Original source Researchers show how their multilegged walking robot can be steered by inducing a dynamic instability. By making the couplings between segments more flexible, the robot changes from walking straight to moving in a curved path. This work can lead to more energy-efficient and reliable robotic navigation of terrain.
Published One-third of galaxy's most common planets could be in habitable zone
(via sciencedaily.com) Original source A third of the exoplanets orbiting common M dwarf stars have gentle enough orbits to potentially be in the habitable zone capable of hosting liquid water.
Published X-ray emissions from black hole jets vary unexpectedly, challenging leading model of particle acceleration
(via sciencedaily.com) Original source Black hole jets are known to emit x-rays, but how they accelerate particles to this high-energy state is still a mystery. Surprising new findings appear to rule out a leading theory, opening the door to reimagining how particle acceleration works. One model of how jets generate x-rays expects the jets' x-ray emissions to remain stable over long time scales. However, the new paper found that the x-ray emissions of a statistically significant number of jets varied over just a few years.
Published Protein-based nano-'computer' evolves in ability to influence cell behavior
(via sciencedaily.com) Original source The first protein-based nano-computing agent that functions as a circuit has been created. The milestone puts them one step closer to developing next-generation cell-based therapies to treat diseases like diabetes and cancer.
Published Effective as a collective: Researchers investigate the swarming behavior of microrobots
(via sciencedaily.com) Original source Miniaturization is progressing rapidly in just any field and the trend towards the creation of ever smaller units is also prevalent in the world of robot technology. In the future, minuscule robots used in medical and pharmaceutical applications might be able to transport medication to targeted sites in the body. Statistical physics can contribute to the foundations for the development of such technologies.
Published Robots and Rights: Confucianism Offers Alternative
(via sciencedaily.com) Original source As robots assume more roles in the world, a new analysis reviewed research on robot rights, concluding that granting rights to robots is a bad idea. Instead, the article looks to Confucianism to offer an alternative.
Published Astronomers discover a key planetary system to understand the formation mechanism of the mysterious 'super-Earths'
(via sciencedaily.com) Original source A study presents the detection of a system of two planets slightly larger than Earth orbiting a cold star in a synchronized dance. Named TOI-2096, the system is located 150 light-years from Earth. This system, located 150 light-years from Earth, is one of the best candidates for a detailed study of their atmosphere with the JWST space telescope.
Published Making the structure of 'fire ice' with nanoparticles
(via sciencedaily.com) Original source Cage structures made with nanoparticles could be a route toward making organized nanostructures with mixed materials, and researchers have shown how to achieve this through computer simulations.
Published Helium nuclei research advances our understanding of cosmic ray origin and propagation
(via sciencedaily.com) Original source The latest observations from Low Earth Orbit with the International Space Station provide further evidence of spectral hardening and softening of cosmic ray particles.
Published Weevils, long-nosed beetles, are unsung heroes of pollination
(via sciencedaily.com) Original source Some of nature's most diverse pollinators often go unnoticed, even by scientists: long-snouted beetles called weevils. A new study provides a deep dive into the more than 600 species of weevils, including ones whose entire life cycles are interwoven with a specific plant that they help pollinate.
Published The metaverse can lead to better science
(via sciencedaily.com) Original source One researcher says we should look beyond the hype to see how virtual reality can make scientists more effective. But to realize the benefits, researchers must also plan well and avoid potential pitfalls.
Published Iron-rich rocks unlock new insights into Earth's planetary history
(via sciencedaily.com) Original source A new study suggests iron-rich ancient sediments may have helped cause some of the largest volcanic events in the planet's history.
Published Scientists propose revolution in complex systems modelling with quantum technologies
(via sciencedaily.com) Original source Scientists have made a significant advancement with quantum technologies that could transform complex systems modelling with an accurate and effective approach that requires significantly re-duced memory.
Published Engineers harvest abundant clean energy from thin air, 24/7
(via sciencedaily.com) Original source A team of engineers has recently shown that nearly any material can be turned into a device that continuously harvests electricity from humidity in the air. Researchers describe the 'generic Air-gen effect'-- nearly any material can be engineered with nanopores to harvest, cost effective, scalable, interruption-free electricity. The secret lies in being able to pepper the material with nanopores less than 100 nanometers in diameter.
Published Medical 'microrobots' could one day treat bladder disease, other human illnesses
(via sciencedaily.com) Original source Engineers have designed a new class of 'microrobots' several times smaller than the width of a human hair that may be able to treat human illnesses like interstitial cystitis -- a painful bladder disease that affects millions of Americans.
Published Quantum matter breakthrough: Tuning density waves
(via sciencedaily.com) Original source Scientists have found a new way to create a crystalline structure called a 'density wave' in an atomic gas. The findings can help us better understand the behavior of quantum matter, one of the most complex problems in physics.
