Published A physical qubit with built-in error correction



Researchers have succeeded in generating a logical qubit from a single light pulse that has the inherent capacity to correct errors.
Published Scammed! Animals 'led by the nose' to leave plants alone



Fake news works for wallabies and elephants. Herbivores can cause substantial damage to crops or endangered or protected plants, with traditional methods to deter foraging lethal, expensive or ineffective. Biologists are now using aromas from plants naturally repellent with remarkable success to deter the animals.
Published Physicists develop highly robust time crystal



Researchers recently succeeded in producing a highly durable time crystal that lived millions of times longer than could be shown in previous experiments. By doing so, they have corroborated an extremely interesting phenomenon that Nobel Prize laureate Frank Wilczek postulated around ten years ago and which had already found its way into science fiction movies.
Published Single proton illuminates perovskite nanocrystals-based transmissive thin scintillators



Researchers have developed a transmissive thin scintillator using perovskite nanocrystals, designed for real-time tracking and counting of single protons. The exceptional sensitivity is attributed to biexcitonic radiative emission generated through proton-induced upconversion and impact ionization.
Published Short X-ray pulses reveal the source of light-induced ferroelectricity in SrTiO3



Researchers have gained new insights into the development of the light-induced ferroelectric state in SrTiO3. They exposed the material to mid-infrared and terahertz frequency laser pulses and found that the fluctuations of its atomic positions are reduced under these conditions. This may explain why the dipolar structure is more ordered than in equilibrium and why the laser pulses induce a ferroelectric state in the material.
Published Scientists make breakthrough in quantum materials research



Researchers describe the discovery of a new method that transforms everyday materials like glass into materials scientists can use to make quantum computers.
Published Discovery of a third RNA virus linage in extreme environments Jan 17, 2024



A research group has discovered a novel RNA viral genome from microbes inhabiting a high-temperature acidic hot spring. Their study shows that RNA viruses can live in high-temperature environments (70-80 degrees Celsius), where no RNA viruses have been observed before. In addition to the two known RNA virus kingdoms, a third kingdom may exist.
Published Researchers craft new way to make high-temperature superconductors -- with a twist



An international team has developed a new method to make and manipulate a widely studied class of high-temperature superconductors. This technique should pave the way for the creation of unusual forms of superconductivity in previously unattainable materials.
Published Superfluids could share characteristic with common fluids



Every fluid -- from Earth's atmosphere to blood pumping through the human body -- has viscosity, a quantifiable characteristic describing how the fluid will deform when it encounters some other matter. If the viscosity is higher, the fluid flows calmly, a state known as laminar. If the viscosity decreases, the fluid undergoes the transition from laminar to turbulent flow. The degree of laminar or turbulent flow is referred to as the Reynolds number, which is inversely proportional to the viscosity. However, this Reynolds similitude does not apply to quantum superfluids. A researcher has theorized a way to examine the Reynolds similitude in superfluids, which could demonstrate the existence of quantum viscosity in superfluids.
Published New research shows how pollutants from aerosols and river run-off are changing the marine phosphorus cycle in coastal seas



New research sheds light on how pollutants from aerosols and river run-off are impacting coastal seas. The research identified an 'Anthropogenic Nitrogen Pump' which changes the phosphorus cycle and therefore likely coastal biodiversity and associated ecosystem services.
Published Scientists pull off quantum coup



Scientists have discovered a first-of-its-kind material, a 3D crystalline metal in which quantum correlations and the geometry of the crystal structure combine to frustrate the movement of electrons and lock them in place.
Published Rising sea levels could lead to more methane emitted from wetlands



A Bay Area wetlands ecosystem that was expected to serve as a carbon sink is emitting surprisingly high levels of methane, a potent greenhouse gas. The study suggests factors governing carbon cycles in these habitats are even more complex than we thought.
Published How waves and mixing drive coastal upwelling systems



Large coastal upwelling systems along the eastern margins of the Atlantic and Pacific Oceans are among the most biologically productive and biodiverse regions of the world's oceans. Typically, the strength and timing of upwelling in such systems are linked to the prevailing winds. Interestingly, in some tropical regions, high levels of productivity occur even when the upwelling favorable winds are weak.
Published Diverse forests are best at standing up to storms



European forests with a greater diversity of tree species are more resilient to storms, according to new research.
Published Shining a light on the hidden properties of quantum materials



Certain materials have desirable properties that are hidden and scientists can use light to uncover these properties. Researchers have used an advanced optical technique, based on terahertz time-domain spectroscopy, to learn more about a quantum material called Ta2NiSe5 (TNS).
Published Microplastics may be accumulating rapidly in endangered Galápagos penguins' food web



Model predictions showed a rapid increase in microplastic accumulation and contamination across the penguins' prey organisms resulting in Galapagos penguin showing the highest level of microplastics per biomass, followed by barracuda, anchovy, sardine, herring, and predatory zooplankton.
Published Researchers add a 'twist' to classical material design



Researchers grew a twisted multilayer crystal structure for the first time and measured the structure's key properties. The twisted structure could help researchers develop next-generation materials for solar cells, quantum computers, lasers and other devices.
Published What coffee with cream can teach us about quantum physics



A new advancement in theoretical physics could, one day, help engineers develop new kinds of computer chips that might store information for longer in very small objects.
Published Gravity helps show strong force strength in the proton



New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force, a powerful mediator of particle interactions in the subatomic realm. The research has revealed, for the first time, a snapshot of the distribution of the shear strength of the strong force inside the proton -- or how strong an effort must be to overcome the strong force to move an object it holds in its grasp. At its peak, the nuclear physicists found that a force of over four metric tons would be required to overcome the binding power of the strong force.
Published Researchers find new multiphoton effect within quantum interference of light



An international team of researchers has disproved a previously held assumption about the impact of multiphoton components in interference effects of thermal fields (e.g. sunlight) and parametric single photons (generated in non-linear crystals).
