Researchers in Spain have discovered that in collectives of moving fire ants, rippling “waves” of density and activity are likely triggered by local regions where ants collectively travel in the same direction as their neighbors.
Quantum mechanics is a physics framework that describes how matter and energy behave at an extremely small scale, specifically at the scale of atoms and subatomic particles. An effect predicted by the laws of quantum mechanics is superposition, which entails that particles can exist in multiple states or positions simultaneously, which remain indefinite until they are measured or observed.
A team of astronomers, led by University of Warwick in collaboration with researchers at MIT and McMaster, have developed a novel method to use the properties of dust rings around stars to estimate the masses of newborn planets. Published in The Astrophysical Journal, this research offers astronomers a new way to find and characterize planets that are too deeply embedded in their birth environment to be seen directly.
SpaceX Starship launches are on hold pending an investigation into last week’s test flight.
Our sun is a loner. It lacks a stellar companion hurtling through interstellar space with it. But we’ve known for a long time that that’s actually relatively rare—most stars have at least one gravitationally bound partner. Understanding how exactly those stars are related to each other is critical for observational campaigns—especially for those of exoplanets. So a new paper posted to the arXiv preprint server from researchers at the University of Madrid that categorizes almost every star within 10 light years into companion categories is a welcome addition to the literature on the subject, and could be used to inform the next round of planet-habitable planet-hunting satellites.
Internal changes due to the sun’s “active biorhythm” have become increasingly “skin-deep” over the past four solar activity cycles, according to a new study.
Astrophysicists think that black hole masses are hierarchical. The largest are supermassive black holes (SMBH) like the one at the center of the Milky Way and other galaxies. Stellar mass black holes are born of collapsing stars, and are smaller. The smallest of all are the theoretical primordial black holes, which only formed in the weird physics of the early universe.
Researchers at TU/e have demonstrated that energy transfer without loss via light or heat can occur over much greater distances than previously thought possible thanks to vibrations in microscopic gold rods. They succeeded in making energy jump from one particle to another over a distance of several millimeters without “spilling” energy along the way.
Quantum computers have the potential to transform science, accelerating breakthroughs in drug development, cosmology, materials science, nuclear physics, and more.
Creating perfect randomness is surprisingly difficult. Even modern random number generators never generate completely ideal random numbers: small systematic errors can result in some numbers appearing slightly more frequently than others. For many applications, this does not matter. In cryptography, however, even the tiniest deviations can be problematic.
This NASA Hubble Space Telescope image features the dwarf irregular galaxy ESO 490-017, roughly 12,000 light-years in diameter and some 23 million light-years away in the constellation Canis Major. The galaxy’s low surface brightness makes it appear as a faint, starry swarm behind brighter foreground stars that are easily recognized by their diffraction spikes. Numerous red, orange, and beige dots are distant galaxies peppering the black background, many exhibiting distinct spiral structure.
Researchers have developed a novel virtual model for simulating how astronauts in future moon base operations might interact with each other and with their environment, with preliminary simulations revealing potential opportunities to boost the chances of a successful mission. Raymond Vera and colleagues at George Mason University in Virginia, U.S., present these findings in PLOS One.
Solar flares are powerful bursts of radiation from the sun’s surface, which can wreak havoc on Earth’s power grids, damage orbiting satellites, and pose serious radiation risks to astronauts. Yet despite decades of study, the processes that trigger these eruptions remain poorly understood.
Ultra-fast data transfer and superconductivity: Quantum materials offer significant technological prospects—if we can understand them at the atomic scale. A team from the University of Geneva (UNIGE), in collaboration with the University of Salerno, the Institute of Materials Science of Barcelona, and the National Research Council of Italy, has succeeded in observing the “quantum metric” in a topological insulator—a unique geometric property of these materials, which conduct electricity only on their surface.
