Published Acceptance of animals in urban environments
(via sciencedaily.com) Original source How do city residents feel about animals in their immediate surroundings? A recent study shows how different the acceptance of various wild animals in urban areas is. Important factors are the places where the animals are found and their level of popularity -- squirrels and ladybugs come out on top here. The results have important implications for urban planning and nature conservation.
Published Turbid waters keep the coast healthy
(via sciencedaily.com) Original source To preserve the important intertidal areas and salt marshes off our coasts for the future, we need more turbid water. That is one of the striking conclusions from a new study.
Published Experiment opens door for millions of qubits on one chip
(via sciencedaily.com) Original source Researchers have achieved the first controllable interaction between two hole spin qubits in a conventional silicon transistor. The breakthrough opens up the possibility of integrating millions of these qubits on a single chip using mature manufacturing processes.
Published New quantum sensing scheme could lead to enhanced high-precision nanoscopic techniques
(via sciencedaily.com) Original source Researchers have unveiled a quantum sensing scheme that achieves the pinnacle of quantum sensitivity in measuring the transverse displacement between two interfering photons.
Published Stony coral tissue loss disease is shifting the ecological balance of Caribbean reefs
(via sciencedaily.com) Original source A new study shows stony coral tissue loss disease is causing drastic changes in the Caribbean's population of corals, which is sure to disrupt the delicate balance of the ecosystem and threaten marine biodiversity and coastal economies.
Published New eco-friendly lubricant additives protect turbine equipment, waterways
(via sciencedaily.com) Original source Scientists have developed lubricant additives that protect both water turbine equipment and the surrounding environment.
Published Oil palm plantations are driving massive downstream impact to watershed
(via sciencedaily.com) Original source The global demand for palm oil -- the most widely consumed vegetable oil on the planet, in everything from instant noodles to lipstick -- is driving worldwide tropical deforestation. While many studies have shown the loss of biodiversity when rainforests are converted to oil palm plantations, researchers have now shown the far-reaching and wide-ranging disturbances to the watersheds in which such plantations occur.
Published Physicists arrange atoms in extremely close proximity
(via sciencedaily.com) Original source Physicists developed a technique to arrange atoms in much closer proximity than previously possible, down to 50 nanometers. The group plans to use the method to manipulate atoms into configurations that could generate the first purely magnetic quantum gate -- a key building block for a new type of quantum computer.
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 To bend the curve of biodiversity loss, nature recovery must be integrated across all sectors
(via sciencedaily.com) Original source The alarming rates of biodiversity loss worldwide have made clear that the classical way of governing biodiversity recovery based on protected areas and programs for the protection of endangered species is not enough. To tackle this, almost 200 countries committed to the active 'mainstreaming' or integration of biodiversity targets into policies and plans across relevant sectors. However, research suggests that this has until now been largely ineffective due to non-binding commitments, vaguely formulated targets, 'add-on' biodiversity initiatives, and too few resources. 'Top down regulation is also needed,' say the authors.
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 Low-intensity grazing is locally better for biodiversity but challenging for land users, a new study shows
(via sciencedaily.com) Original source A team of researchers has investigated the motivation and potential incentives for and challenges of low-intensity grazing among farmers and land users in Europe.
Published Unlocking the genetic mysteries behind plant adaptation: New insights into the evolution of a water-saving trait in the pineapple family (bromeliaceae)
(via sciencedaily.com) Original source Researchers have achieved a breakthrough in understanding how genetic drivers influence the evolution of a specific photosynthesis mechanism in Tillandsia (air plants). This sheds light on the complex actions that cause plant adaptation and ecological diversity.
Published Fading lights: Multiple threats to North America's firefly populations
(via sciencedaily.com) Original source Scientists have applied a data-driven approach to understanding firefly population dynamics on a continental scale. Key findings from this new study indicate that fireflies, part of the beetle order, are sensitive to various environmental factors, from short-term weather conditions to longer climatic trends, including the number of growing-degree days related to temperature accumulations.
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 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 Climate change could become the main driver of biodiversity decline by mid-century
(via sciencedaily.com) Original source Global biodiversity has declined between 2% and 11% during the 20th century due to land-use change alone, according to a large multi-model study. Projections show climate change could become the main driver of biodiversity decline by the mid-21st century.
