Published Breakthrough may clear major hurdle for quantum computers
(via sciencedaily.com) Original source The potential of quantum computers is currently thwarted by a trade-off problem. Quantum systems that can carry out complex operations are less tolerant to errors and noise, while systems that are more protected against noise are harder and slower to compute with. Now a research team has created a unique system that combats the dilemma, thus paving the way for longer computation time and more robust quantum computers.
Published New material puts eco-friendly methanol conversion within reach
(via sciencedaily.com) Original source Researchers have developed innovative, eco-friendly quantum materials that can drive the transformation of methanol into ethylene glycol. This discovery opens up new possibilities for using eco-friendly materials in photocatalysis, paving the way for sustainable chemical production.
Published 'Lost' birds list will aid in protecting species
(via sciencedaily.com) Original source A group of scientists has released the first comprehensive list of birds that haven't been documented with sound or video in more than a decade.
Published Quantum entanglement measures Earth rotation
(via sciencedaily.com) Original source Researchers carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work represents a significant achievement that pushes the boundaries of rotation sensitivity in entanglement-based sensors, potentially setting the stage for further exploration at the intersection between quantum mechanics and general relativity.
Published A liquid crystal source of photon pairs
(via sciencedaily.com) Original source Spontaneous parametric down-conversion (SPDC), as a source of entangled photons, is of great interest for quantum physics and quantum technology, but so far it could be only implemented in solids. Researchers have demonstrated, for the first time, SPDC in a liquid crystal. The results open a path to a new generation of quantum sources: efficient and electric-field tunable.
Published Tiny New Zealand bird delivers a lesson in birdsong evolution
(via sciencedaily.com) Original source Scientists are rethinking the evolution of vocal learning in birds. New Zealand's smallest bird, the rifleman or titipounamu, may have a rudimentary version of the talent possessed by parrots, hummingbirds and songbirds.
Published The scary, yet promising world of phages, the pathogen's pathogen
(via sciencedaily.com) Original source Researchers are unlocking the mystery of how bacteria harness viruses to wipe out the competition. The answers could help spur the development of alternatives to antibiotics.
Published Outdoor recreation noise affects wildlife behavior and habitat use, study finds
(via sciencedaily.com) Original source We may go to the woods seeking peace and quiet, but are we taking our noise with us? A recent study indicates that the answer is yes -- and that this noise can trigger a fear response, as if escaping from predators. This new science calls into question whether otherwise high-quality habitat truly provides refugia for wildlife when recreationists are present and underscores the challenges land managers face in balancing outdoor recreational opportunities with wildlife conservation.
Published Quantum data assimilation: A quantum leap in weather prediction
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source A team has developed printable, highly efficient light-emitting metasurfaces.
Published Humans are the elephant in the room where conservation is debated
(via sciencedaily.com) Original source Studies working to map conservation historically have left humans out of the equation. This study proposes ways to build in the outsized footprint created by people in wild places.
Published Specialist and migratory birds at greater risk under climate change
(via sciencedaily.com) Original source Following decades of decline, even fewer birds will darken North American skies by the end of the century, according to a new analysis. The study examines the long-term effects of climate change on the abundance and diversity of bird groups across the continent as a whole while accounting for additional factors that put birds at risk.
Published New technique could help build quantum computers of the future
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Lazy predator: A new species of mountain pitviper from China
(via sciencedaily.com) Original source Researchers have discovered a new species of medium-sized venomous snake in Yunnan, China. Ovophis jenkinsi is dark brownish-grey in color with trapezoidal patches on its back. It is endemic to China's Yingjiang County and is not difficult to find in the wild. In the future, researchers plan to collect more information about this new species, including its appearance, distribution, and habits.
Published Two can play that game: juvenile dolphins who play together are more successful as adults
(via sciencedaily.com) Original source Juvenile social play predicts adult reproductive success in male bottlenose dolphins, a new study has found.
Published Elephants have names for each other like people do, new study shows
(via sciencedaily.com) Original source Wild African elephants address each other with name-like calls, a rare ability among nonhuman animals, according to a new study. Researchers used machine learning to confirm that elephant calls contained a name-like component identifying the intended recipient, a behavior they suspected based on observation. The study suggests elephants do not imitate the receiver's call to address one another but instead use arbitrary vocal labels like humans.
Published Perturbations simplify the study of 'super photons'
(via sciencedaily.com) Original source 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 Fish out of water: How killifish embryos adapted their development
(via sciencedaily.com) Original source The annual killifish lives in regions with extreme drought. A research group now reports that the early embryogenesis of killifish diverges from that of other species. Unlike other fish, their body structure is not predetermined from the outset. This could enable the species to survive dry periods unscathed.
Published Novel diamond quantum magnetometer for ambient condition magnetoencephalography
(via sciencedaily.com) Original source 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.
