Astronomers have found an exoplanet that could serve as a benchmark in future studies. It’s a rocky planet orbiting an M-type star, and though these planets are plentiful, this one could serve as a benchmark for understanding other M-dwarf exoplanets and their atmospheres. According to the authors of a new study, this new exoplanet could serve as “a reference system for highly irradiated rocky planets.”
Fleeting electron-hole pairs are giving scientists a new window into optimizing light-emitting devices (LEDs). Using quantum magnetic resonance, Osaka Metropolitan University researchers have discovered how shifting internal electric fields dictate whether these devices shine brightly or dimly. Their study is published in the journal Advanced Optical Materials.
West Bloomfield PD Chief Dale Young stated that after a 911 call reported an active shooter at Temple Israel, officers were on the scene in less than five minutes and immediately cleared the building
Although the potential applications of quantum computing are widespread, a new feasibility study suggests quantum computers still face major hurdles in solving quantum chemistry problems. The study, published in Physical Review B, evaluates what criteria are needed for a quantum advantage in searching for the ground state energy of molecules. The researchers attempt this feat using two different algorithms with differing strengths and weaknesses.
Cosmic rays are one of the greatest challenges for space travel and pose a considerable risk to humans and materials. For the first time on European soil, an international research team in collaboration with the European Space Agency (ESA) has succeeded in providing a simulator for galactic cosmic rays at the GSI/FAIR accelerator facility in Darmstadt, Germany. The results have been published in two articles in the journal Life Sciences in Space Research.
For the first time, researchers in China have demonstrated how quantum dots can be engineered to consistently generate pairs of entangled photons. By carefully tailoring the photonic environment surrounding a single quantum dot, the team showed that it is possible to produce highly correlated photon pairs with remarkable efficiency, potentially opening new opportunities for emerging quantum technologies. The work, led by Zhiliang Yuan at the Beijing Academy of Quantum Information Sciences, is reported in Nature Materials.
Video from the scene shows the man, who was holding a knife in each hand, advancing toward Buffalo Police officers, prompting the fatal shooting
Nuclear isomers are crucial probes for studying the structure of nuclei. Unlike chemical isomers—which have the same chemical formula but different arrangements of atoms—nuclear isomers are nuclei that exist in a long-lived and relatively stable excited state.
The shooter, who shouted “Allahu Akbar” before opening fire at Old Dominion University had previously spent eight years in prison for attempting to aid the Islamic State
Researchers at University of Tsukuba have developed a noncontact vibration measurement method using an event camera, a sensing technology inspired by biological vision. By applying geometric analysis to event-stream data, the team succeeded in reconstructing vibrations—an achievement that had posed substantial challenges using an event camera.
Light-based quantum technologies, such as quantum communication and photonic quantum computing, require reliable sources of individual photons and, ideally, pairs of entangled photons. Semiconductor quantum dots are promising candidates for this purpose. These nanostructures have electrical conductivity between that of insulators and conductors and are capable of confining electrons and holes. This property causes them to emit light at well-defined frequencies when excited by a laser.
A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest building blocks in nature: atomic nuclei. In new research published in Nature Communications, the team uses machine learning and artificial intelligence to decipher the data from astrophysical observations to better understand how neutrons and protons interact in dense matter at the quantum level.
Astronomers have found that both the core of our Milky Way and the earliest proto-galaxies in the universe share a surprising trait: They are unusually calm and quiet in terms of harsh radiation. This tranquility is not just a cosmic curiosity; it may be essential for forming complex molecules that provide the ingredients of life.
Two powerful instruments of the NASA/ESA/CSA James Webb Space Telescope joined forces to create this scenic galaxy view. This spiral galaxy is named NGC 5134, and it is located 65 million light-years away in the constellation Virgo. Though 65 million light-years may seem like a huge distance—the light that Webb collected to create this image has been journeying to us from NGC 5134 since soon after Tyrannosaurus rex went extinct—NGC 5134 is fairly close by as far as galaxies go. Because of the galaxy’s relative proximity, Webb can spot incredible details in its tightly wound spiral arms.
NASA cleared its moon rocket on Thursday for an April launch with four astronauts after completing the latest round of repairs.
