Published Magnetism fosters unusual electronic order in quantum material
(via sciencedaily.com) Physicists have published an array of experimental evidence showing that the ordered magnetic arrangement of electrons in crystals of iron-germanium plays an integral role in bringing about an ordered electronic arrangement called a charge density wave that the team discovered in the material last year.
Published Scientists transform algae into unique functional perovskites with tunable properties
(via sciencedaily.com) Scientists have transformed single-cell algae into functional perovskite materials. The team has converted mineral shells of algae into lead halide perovskites with tunable physical properties. The new perovskites have unique nano-architectures unachievable by conventional synthetic production. The method can be applied to the mass production of perovskites with tunable structural and electro-optical properties from single-celled organisms.
Published Experiment unlocks bizarre properties of strange metals
(via sciencedaily.com) Physicists are learning more about the bizarre behavior of 'strange metals,' which operate outside the normal rules of electricity.
Published Surprising similarities in stone tools of early humans and monkeys
(via sciencedaily.com) Researchers have discovered artefacts produced by old world monkeys in Thailand that resemble stone tools, which historically have been identified as intentionally made by early hominins. Until now, sharp-edged stone tools were thought to represent the onset of intentional stone tool production, one of the defining and unique characteristics of hominin evolution. This new study challenges long held beliefs about the origins of intentional tool production in our own lineage.
Published Jewel beetles evolve to see new colors by duplicating their genes
(via sciencedaily.com) Jewel beetles are striking insects, easily recognized by their vivid colors and metallic sheen. New research investigated the complex evolutionary history of jewel beetles' vision.
Published In the world's smallest ball game, scientists throw and catch single atoms using light
(via sciencedaily.com) Researchers show that individual atoms can be caught and thrown using light. This is the first time an atom has been released from a trap -- or thrown -- and then caught by another trap. This technology could be used in quantum computing applications.
Published Hitting nuclei with light may create fluid primordial matter
(via sciencedaily.com) A new analysis supports the idea that photons colliding with heavy ions create a fluid of 'strongly interacting' particles. The results indicate that photon-heavy ion collisions can create a strongly interacting fluid that responds to the initial collision geometry and that these collisions can form a quark-gluon plasma. These findings will help guide future experiments at the planned Electron-Ion Collider.
Published Researchers take a step towards turning interactions that normally ruin quantum information into a way of protecting it
(via sciencedaily.com) A new method for predicting the behavior of quantum devices provides a crucial tool for real-world applications of quantum technology.
Published Graphene quantum dots show promise as novel magnetic field sensors
(via sciencedaily.com) Trapped electrons traveling in circular loops at extreme speeds inside graphene quantum dots are highly sensitive to external magnetic fields and could be used as novel magnetic field sensors with unique capabilities, according to a new study.
Published Two-dimensional quantum freeze
(via sciencedaily.com) Researchers have succeeded in simultaneously cooling the motion of a tiny glass sphere in two dimensions to the quantum ground-state. This represents a crucial step towards a 3D ground-state cooling of a massive object and opens up new opportunities for the design of ultra-sensitive sensors.
Published An innovative twist on quantum bits: Tubular nanomaterial of carbon makes ideal home for spinning quantum bits
(via sciencedaily.com) Scientists develop method for chemically modifying nanoscale tubes of carbon atoms, so they can host spinning electrons to serve as stable quantum bits in quantum technologies.
Published Illuminating the evolution of social parasite ants
(via sciencedaily.com) The findings offer a new way to understand how some ants become total layabouts.
Published Fluorescent protein sheds light on bee brains
(via sciencedaily.com) An international team of bee researchers has integrated a calcium sensor into honey bees to enable the study of neural information processing including response to odors. This also provides insights into how social behavior is located in the brain.
Published Quantum chemistry: Molecules caught tunneling
(via sciencedaily.com) Quantum effects can play an important role in chemical reactions. Physicists have now observed a quantum mechanical tunneling reaction in experiments. The observation can also be described exactly in theory. The scientists provide an important reference for this fundamental effect in chemistry. It is the slowest reaction with charged particles ever observed.
Published Pink + pink = gold: hybrid hummingbird's feathers don't match its parents
(via sciencedaily.com) Scientists thought a gold-throated hummingbird was a new species. DNA revealed that it's a hybrid of two different species, each with pink throats. The discovery sheds light on how birds produce feather colors and how hummingbirds evolved their dazzling hues.
Published Better metric for prioritizing conservation of 'evolutionarily distinctive' species
(via sciencedaily.com) Researchers have published an updated metric for prioritizing species' conservation that incorporates scientific uncertainty and complementarity between species, in addition to extinction risk and evolutionary distinctiveness.
Published Parental investment may have aided evolution of larger brains
(via sciencedaily.com) A review of evidence from prior research provides new support for the possibility that the evolution of larger brains in some species was enabled through increased energy investment by parents in their offspring.
Published Jurassic shark: Shark from the Jurassic period was already highly evolved
(via sciencedaily.com) Cartilaginous fish have changed much more in the course of their evolutionary history than previously believed. Evidence for this thesis has been provided by new fossils of a ray-like shark, Protospinax annectans, which demonstrate that sharks were already highly evolved in the Late Jurassic.
Published Who are the first ancestors of present-day fish?
(via sciencedaily.com) What is the origin of the ancestors of present-day fish? What species evolved from them? A 50-year-old scientific controversy revolved around the question of which group, the 'bony-tongues' or the 'eels', was the oldest. A study has just put an end to the debate by showing through genomic analysis that these fishes are in fact one and the same group, given the rather peculiar name of 'Eloposteoglossocephala'. These results shed new light on the evolutionary history of fish.
Published Evolutionary history of detoxifying enzymes reconstructed
(via sciencedaily.com) Biochemists have succeeded in resurrecting the ancestral genes of five detoxifying enzymes which are present in all tetrapods to show how their divergence in function has occurred.
