Published Scientists test for quantum nature of gravity
(via sciencedaily.com) Original source A new study reports on a deep new probe into the interface between the theories of gravity and quantum mechanics, using ultra-high energy neutrino particles detected by a particle detector set deep into the Antarctic glacier at the south pole.
Published Significant new discovery in teleportation research -- Noise can improve the quality of quantum teleportation
(via sciencedaily.com) Original source Researchers succeeded in conducting an almost perfect quantum teleportation despite the presence of noise that usually disrupts the transfer of quantum state.
Published The big quantum chill: Scientists modify common lab refrigerator to cool faster with less energy
(via sciencedaily.com) Original source Scientists have dramatically reduced the time and energy required to chill materials to temperatures near absolute zero. Their prototype refrigerator could prove a boon for the burgeoning quantum industry, which widely uses ultracold materials.
Published Researchers unlock potential of 2D magnetic devices for future computing
(via sciencedaily.com) Original source A research team has created an innovative method to control tiny magnetic states within ultrathin, two-dimensional van der Waals magnets -- a process akin to how flipping a light switch controls a bulb.
Published Rock solid evidence: Angola geology reveals prehistoric split between South America and Africa
(via sciencedaily.com) Original source A research team has found that ancient rocks and fossils from long-extinct marine reptiles in Angola clearly show a key part of Earth's past -- the splitting of South America and Africa and the subsequent formation of the South Atlantic Ocean.
Published Revised dating of the Liujiang skeleton renews understanding of human occupation of China
(via sciencedaily.com) Original source Researchers have provided new age estimates and revised provenance information for the Liujiang human fossils, shedding light on the presence of Homo sapiens in the region. Using advanced dating techniques including U-series dating on human fossils, and radiocarbon and optically stimulated luminescence dating on fossil-bearing sediments, the study revealed new ages ranging from approximately 33,000 to 23,000 years ago. Previously, studies had reported ages of up to 227,000 years of age for the skeleton.
Published Astronomers' simulations support dark matter theory
(via sciencedaily.com) Original source Computer simulations by astronomers support the idea that dark matter -- matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe -- exists, according to the researchers.
Published Atomic nucleus excited with laser: a breakthrough after decades
(via sciencedaily.com) Original source For the first time, the state of an atomic nucleus was switched with a laser. For decades, physicists have been looking for such a nuclear transition -- now it has been found. This opens up a new field of research with many technological applications. Now, nuclei can be used for extremely precise measurements. For example, a nuclear clock could be built that could measure time more precisely than the best atomic clocks available today.
Published Physicists show that light can generate electricity even in translucent materials
(via sciencedaily.com) Original source Some materials are transparent to light of a certain frequency. When such light is shone on them, electrical currents can still be generated, contrary to previous assumptions. Scientists have managed to prove this.
Published T. Rex not as smart as previously claimed
(via sciencedaily.com) Original source Dinosaurs were likely as smart as reptiles but not as intelligent as monkeys.
Published The end of the quantum tunnel
(via sciencedaily.com) Original source Quantum mechanical effects such as radioactive decay, or more generally: 'tunneling', display intriguing mathematical patterns. Researchers now show that a 40-year-old mathematical discovery can be used to fully encode and understand this structure.
Published From disorder to order: Flocking birds and 'spinning' particles
(via sciencedaily.com) Original source Researchers have demonstrated that ferromagnetism, an ordered state of atoms, can be induced by increasing particle motility and that repulsive forces between atoms are sufficient to maintain it. The discovery not only extends the concept of active matter to quantum systems but also contributes to the development of novel technologies that rely on the magnetic properties of particles, such as magnetic memory and quantum computing.
Published Ancient Maya blessed their ballcourts
(via sciencedaily.com) Original source Using environmental DNA analysis, an international team of researchers identified a collection of plants used in ceremonial rituals in the ancient Maya city of Yaxnohcah in Mexico. The plants, known for their religious associations and medicinal properties, were discovered beneath a plaza floor where a ballcourt was built.
Published Scientists tune the entanglement structure in an array of qubits
(via sciencedaily.com) Original source A new technique can generate batches of certain entangled states in a quantum processor. This advance could help scientists study the fundamental quantum property of entanglement and enable them to build larger and more complex quantum processors.
Published These giant, prehistoric salmon had tusk-like teeth
(via sciencedaily.com) Original source Oncorhynchus rastrosus, a giant species of salmon that lived in the North American Pacific Northwest a few million years ago, sported a pair of front teeth that projected out from the sides of its mouth like tusks, according to a new study.
Published Researchers find oldest undisputed evidence of Earth's magnetic field
(via sciencedaily.com) Original source A new study has recovered a 3.7-billion-year-old record of Earth's magnetic field, and found that it appears remarkably similar to the field surrounding Earth today.
Published Condensed matter physics: Novel one-dimensional superconductor
(via sciencedaily.com) Original source In a significant development in the field of superconductivity, researchers have successfully achieved robust superconductivity in high magnetic fields using a newly created one-dimensional (1D) system. This breakthrough offers a promising pathway to achieving superconductivity in the quantum Hall regime, a longstanding challenge in condensed matter physics.
Published Lead-vacancy centers in diamond as building blocks for large-scale quantum networks
(via sciencedaily.com) Original source A lead-vacancy (PbV) center in diamond has been developed as a quantum emitter for large-scale quantum networks by researchers. This innovative color center exhibits a sharp zero-phonon-line and emits photons with specific frequencies. The PbV color center stands out among other diamond color centers due to its ability to maintain optical properties at relatively high temperatures of 16 K. This makes it well-suited for transferring quantum information in large-scale quantum networks.
Published Bioluminescence first evolved in animals at least 540 million years ago
(via sciencedaily.com) Original source Bioluminescence first evolved in animals at least 540 million years ago in a group of marine invertebrates called octocorals, according to the results of a new study. The study focuses on an ancient group of marine invertebrates that includes soft corals, pushes back the previous oldest dated example of trait by nearly 300 million years.
Published Manipulating the geometry of 'electron universe' in magnets
(via sciencedaily.com) Original source Researchers have discovered a unique property, the quantum metric, within magnetic materials, altering the 'electron universe' geometry. This distinct electric signal challenges traditional electrical conduction and could revolutionize spintronic devices.
