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 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 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 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.
Published Researchers build bee robot that can twist
(via sciencedaily.com) Original source A robotic bee that can fly fully in all directions has been developed. With four wings made out of carbon fiber and mylar as well as four light-weight actuators to control each wing, the Bee++ prototype is the first to fly stably in all directions. That includes the tricky twisting motion known as yaw, with the Bee++ fully achieving the six degrees of free movement that a typical flying insect displays.
Published Wiring up quantum circuits with light
(via sciencedaily.com) Original source The number of qubits in superconducting quantum computers has risen rapidly during the last years, but further growth is limited by the need for ultra-cold operating temperatures. Connecting several smaller processors could create larger, more computationally powerful quantum computers -- however doing so poses new challenges. Researchers have now demonstrated quantum entanglement between optical and microwave photons that could lay the foundation for such a future quantum network.
Published Radio signal reveals supernova origin
(via sciencedaily.com) Original source Astronomers reveal the origin of a thermonuclear supernova explosion. Strong emission lines of helium and the first detection of such a supernova in radio waves show that the exploding white dwarf star had a helium-rich companion.
Published Astronomers observe the first radiation belt seen outside of our solar system
(via sciencedaily.com) Original source Astronomers have described the first radiation belt observed outside our solar system, using a coordinated array of 39 radio dishes from Hawaii to Germany to obtain high-resolution images. The images of persistent, intense radio emissions from an ultracool dwarf reveal the presence of a cloud of high-energy electrons trapped in the object's powerful magnetic field, forming a double-lobed structure analogous to radio images of Jupiter's radiation belts.
Published New study puts a definitive age on Saturn's rings -- they're really young
(via sciencedaily.com) Original source Physicists measured the flux of interplanetary dust around Saturn. The researchers concluded that the planet's rings formed less than 400 million years ago, making them much younger than Saturn itself.
Published Astronomers reveal the largest cosmic explosion ever seen
(via sciencedaily.com) Original source Astronomers have uncovered the largest cosmic explosion ever witnessed. The explosion is more than ten times brighter than any known supernova and three times brighter than the brightest tidal disruption event, where a star falls into a supermassive black hole.
Published Hidden supermassive black holes brought to life by galaxies on collision course
(via sciencedaily.com) Original source Astronomers have found that supermassive black holes obscured by dust are more likely to grow and release tremendous amounts of energy when they are inside galaxies that are expected to collide with a neighbouring galaxy.
Published Robotic proxy brings remote users to life in real time
(via sciencedaily.com) Original source Researchers have developed a robot, called ReMotion, that occupies physical space on a remote user's behalf, automatically mirroring the user's movements in real time and conveying key body language that is lost in standard virtual environments.
Published Measurement of the Universe's expansion rate weighs in on a longstanding debate in physics and astronomy
(via sciencedaily.com) Original source A team used a first-of-its-kind technique to measure the expansion rate of the Universe, providing insight that could help more accurately determine the Universe's age and help physicists and astronomers better understand the cosmos.
Published Astronomers find no young binary stars near Milky Way's black hole
(via sciencedaily.com) Original source Scientists analyzed over a decade's worth of data about 16 young supermassive stars orbiting the supermassive black hole at the center of the Milky Way galaxy. Supermassive stars typically are formed in pairs, but the new study found that all 16 of the stars were singletons. The findings support a scenario in which the supermassive black hole drives nearby stars to either merge or be disrupted, with one of the pair being ejected from the system.
Published Researchers measure the light emitted by a sub-Neptune planet's atmosphere
(via sciencedaily.com) Original source Researchers observed exoplanet GJ 1214b's atmosphere by measuring the heat it emits while orbiting its host star. Astronomers directly detected the light emitted by a sub-Neptune exoplanet -- a category of planets that are larger than Earth but smaller than Neptune.
