Published Ancient ocean slowdown warns of future climate chaos



When it comes to the ocean's response to global warming, we're not in entirely uncharted waters. A new study shows that episodes of extreme heat in Earth's past caused the exchange of waters from the surface to the deep ocean to decline.
Published Quantum data assimilation: A quantum leap in weather prediction



Data assimilation is an important mathematical discipline in earth sciences, particularly in numerical weather prediction (NWP). However, conventional data assimilation methods require significant computational resources. To address this, researchers developed a novel method to solve data assimilation on quantum computers, significantly reducing the computation time. The findings of the study have the potential to advance NWP systems and will inspire practical applications of quantum computers for advancing data assimilation.
Published Quantum dots and metasurfaces: Deep connections in the nano world



A team has developed printable, highly efficient light-emitting metasurfaces.
Published No bones about it: 100-million-year-old bones reveal new species of pterosaur



New research has identified 100-million-year-old fossilized bones discovered in western Queensland as belonging to a newly identified species of pterosaur, which was a formidable flying reptile that lived among the dinosaurs.
Published Uncovering the nature of emergent magnetic monopoles



To understand the unique physical phenomena associated with the properties of magnetic hedgehogs and antihedgehogs, which behave as virtual magnetic monopoles and antimonopoles respectively, it is essential to study their intrinsic excitations. In a new study, researchers revealed the dynamical nature of collective excitation modes in hedgehog lattices in itinerant chiral magnets. Their findings serve as the foundation for studying the dynamics of emergent magnetic monopoles in magnets.
Published New technique could help build quantum computers of the future



Researchers have demonstrated a new method that could enable the large-scale manufacturing of optical qubits. The advance could bring us closer to a scalable quantum computer.
Published Switching nanomagnets using infrared lasers



Physicists have calculated how suitable molecules can be stimulated by infrared light pulses to form tiny magnetic fields. If this is also successful in experiments, the principle could be used in quantum computer circuits.
Published 'Quantum optical antennas' provide more powerful measurements on the atomic level



A multi-institutional team has created atomic optical antennas in solids. The team used germanium vacancy centers in diamonds to create an optical energy enhancement of six orders of magnitude, a regime challenging to reach with conventional atomic antenna structures.
Published Tiny new species of great ape lived in Germany 11 million years ago



Ancient apes in Germany co-existed by partitioning resources in their environment, according to a new study.
Published Perturbations simplify the study of 'super photons'



Thousands of particles of light can merge into a type of 'super photon' under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers have now shown that this exotic quantum state obeys a fundamental theorem of physics. This finding now allows one to measure properties of photon Bose-Einstein condensates which are usually difficult to access.
Published Novel diamond quantum magnetometer for ambient condition magnetoencephalography



A highly sensitive diamond quantum magnetometer utilizing nitrogen-vacancy centers can achieve millimeter-scale resolution magnetoencephalography (MEG). The novel magnetometer, based on continuous-wave optically detected magnetic resonance, marks a significant step towards realizing ambient condition MEG and other practical applications.
Published Tiny roundworms carve out unique parasitic niche inside pseudoscorpion's protective covering



In a parasitic first, a Baltic amber specimen has revealed that millions of years ago tiny worms known as nematodes were living inside of and feeding on the outer protective layer of pseudoscorpions.
Published Fishy mystery of marine reptile solved



The identity of a prehistoric marine reptile has finally been revealed after experts discovered that some of its remains actually belonged to fish.
Published 'Missing' early sea sponges discovered



Geobiologists reported a 550 million-year-old sea sponge that had been missing from the fossil record. The discovery sheds new light on a conundrum that has stumped zoologists and paleontologists for years.
Published Gigantic Jurassic pterosaur fossil unearthed in Oxfordshire, UK



A team of palaeontologists has discovered a fossil of a gigantic flying reptile from the Jurassic period with an estimated wingspan of more than three metres -- making it one of the largest pterosaurs ever found from that era.
Published Shining a light on molecules: L-shaped metamaterials can control light direction



Polarized light waves spin clockwise or counterclockwise as they travel, with one direction behaving differently than the other as it interacts with molecules. This directionality, called chirality or handedness, could provide a way to identify and sort specific molecules for use in biomedicine applications, but researchers have had limited control over the direction of the waves -- until now.
Published Groundbreaking progress in quantum physics: How quantum field theories decay and fission



An international research team has sparked interest in the scientific community with results in quantum physics. In their current study, the researchers reinterpret the Higgs mechanism, which gives elementary particles mass and triggers phase transitions, using the concept of 'magnetic quivers.'
Published How sharks survived a major spike in Earth's temperature



The sharks we know today as the open ocean's top predators evolved from stubby bottom dwellers during a dramatic episode of global warming millions of years ago.
Published The coldest lab in New York has new quantum offering



Physicists describe the successful creation of a molecular Bose-Einstein condensate (BEC). Made up of dipolar sodium-cesium molecules that were cooled with the help of microwave shielding to just 5 nanoKelvin and lasted for up to two seconds, the new molecular BEC will help scientists explore a number of different quantum phenomena, including new types of superfluidity, and enable the creation of quantum simulators to ecreate the enigmatic properties of complex materials, like solid crystals.
Published An unlikely hero in evolution: Worms



One of Earth's most consequential bursts of biodiversity -- a 30-million-year period of explosive evolutionary changes spawning innumerable new species -- may have the most modest of creatures to thank for the vital stage in life's history: worms.
