Published In the world's smallest ball game, scientists throw and catch single atoms using light


Researchers show that individual atoms can be caught and thrown using light. This is the first time an atom has been released from a trap -- or thrown -- and then caught by another trap. This technology could be used in quantum computing applications.
Published Researchers take a step towards turning interactions that normally ruin quantum information into a way of protecting it


A new method for predicting the behavior of quantum devices provides a crucial tool for real-world applications of quantum technology.
Published ALMA traces history of water in planet formation back to the interstellar medium


Observations of water in the disk forming around protostar V883 Ori have unlocked clues about the formation of comets and planetesimals in our own solar system.
Published The planet that could end life on Earth


A terrestrial planet hovering between Mars and Jupiter would be able to push Earth out of the solar system and wipe out life on this planet, according to a recent experiment.
Published Two-dimensional quantum freeze


Researchers have succeeded in simultaneously cooling the motion of a tiny glass sphere in two dimensions to the quantum ground-state. This represents a crucial step towards a 3D ground-state cooling of a massive object and opens up new opportunities for the design of ultra-sensitive sensors.
Published Can artificial intelligence help find life on Mars or icy worlds?


Researchers have mapped the sparse life hidden away in salt domes, rocks and crystals at Salar de Pajonales at the boundary of the Chilean Atacama Desert and Altiplano. Then they trained a machine learning model to recognize the patterns and rules associated with their distributions so it could learn to predict and find those same distributions in data on which it was not trained. In this case, by combining statistical ecology with AI/ML, the scientists could locate and detect biosignatures up to 87.5 percent of the time and decrease the area needed for search by up to 97 percent.
Published An innovative twist on quantum bits: Tubular nanomaterial of carbon makes ideal home for spinning quantum bits


Scientists develop method for chemically modifying nanoscale tubes of carbon atoms, so they can host spinning electrons to serve as stable quantum bits in quantum technologies.
Published Resurrected supernova provides missing link


Astronomers have discovered a supernova exhibiting unprecedented rebrightening at millimeter wavelengths, providing an intermediate case between two types of supernovae: those of solitary stars and those in close-binary systems.
Published Hansel and Gretel's breadcrumb trick inspires robotic exploration of caves on Mars and beyond


Future space missions likely will send robots to scout out underground habitats for astronauts. Engineers have now developed a system that would enable autonomous vehicles to explore caves, lava tubes and even oceans on other worlds on their own.
Published Ultracool dwarf binary stars break records


Astrophysicists have discovered the tightest ultracool dwarf binary system ever observed. The two stars are so close that it takes them less than one Earth day to revolve around each other. In other words, each star's 'year' lasts just 17 hours.
Published Quantum chemistry: Molecules caught tunneling


Quantum effects can play an important role in chemical reactions. Physicists have now observed a quantum mechanical tunneling reaction in experiments. The observation can also be described exactly in theory. The scientists provide an important reference for this fundamental effect in chemistry. It is the slowest reaction with charged particles ever observed.
Published Baby star near the black hole in the middle of our Milky Way: It exists after all


Scientists have detected the heaviest and youngest infant star ever discovered close to the black hole at the center of our Galaxy. They also identified the region where this 'impossible star' may have formed.
Published Liquid nitrogen spray could clean up stubborn moon dust


A liquid nitrogen spray can remove almost all of the simulated moon dust from a space suit, potentially solving what is a significant challenge for future moon-landing astronauts.
Published Galactic explosion offers astrophysicists new insight into the cosmos


Using data from the James Webb Space Telescope's first year of interstellar observation, an international team of researchers was able to serendipitously view an exploding supernova in a faraway spiral galaxy.
Published Astronomers discover metal-rich galaxies in early universe


While analyzing data from the first images of a well-known early galaxy taken by NASA's James Webb Space Telescope (JWST), astronomers discovered a companion galaxy previously hidden behind the light of the foreground galaxy -- one that surprisingly seems to have already hosted multiple generations of stars despite its young age, estimated at 1.4 billion years old.
Published New material may offer key to solving quantum computing issue


A new form of heterostructure of layered two-dimensional (2D) materials may enable quantum computing to overcome key barriers to its widespread application, according to an international team of researchers.
Published A mysterious object is being dragged into the supermassive black hole at the Milky Way's center


An object near the supermassive black hole at the center of the Milky Way galaxy has drawn the interest of scientists because it has evolved dramatically in a relatively short time. A new study suggests that the object, called X7, could be a cloud of dust and gas that was created when two stars collided. The researchers believe it will eventually be drawn toward the black hole and will disintegrate.
Published New discovery sheds light on very early supermassive black holes


Astronomers have discovered a rapidly growing black hole in one of the most extreme galaxies known in the very early Universe. The discovery of the galaxy and the black hole at its center provides new clues on the formation of the very first supermassive black holes.
Published Breakthrough in tin-vacancy centers for quantum network applications


Tin-vacancy (Sn-V) centers in diamond have the potential to function as quantum nodes in quantum networks to transmit information. However, they pose limitations while showing optical properties to generate quantum entanglement. Researchers have now overcome this challenge by generating stable Sn-V centers that can produce photons with nearly identical frequencies and linewidths, paving the way for the advancement of Sn-V centers as a quantum-light matter interface.
Published Discovery of massive early galaxies defies prior understanding of the universe


Six massive galaxies discovered in the early universe are upending what scientists previously understood about the origins of galaxies in the universe.
