Published Island-inhabiting giants, dwarfs more vulnerable to extinction
(via sciencedaily.com) Island-dwelling mammal species often expand or contract in size, becoming giant or dwarf versions of their mainland counterparts. A new Science study from a global team shows that those giants and dwarfs have faced extreme risk of extinction -- an existential threat exacerbated by the arrival of humans.
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 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 Plant roots fuel tropical soil animal communities
(via sciencedaily.com) A research team has shed new light on the importance of plant roots for below-ground life, particularly in the tropics. Millions of small creatures toiling in a single hectare of soil including earthworms, springtails, mites, insects, and other arthropods are crucial for decomposition and soil health. For a long time, it was believed that leaf litter is the primary resource for these animals. However, this recent study is the first to provide proof that resources derived from plant roots drive soil animal communities in the tropics.
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 Drones detect moss beds and changes to Antarctica climate
(via sciencedaily.com) Researchers are using drones with highly advanced sensors and AI to map large areas and to study changes to Antarctica's climate.
Published Earlier take-off could lead to fewer bumblebees and less pollination
(via sciencedaily.com) With the arrival of spring, bumblebee queens take their first wing beat of the season and set out to find new nesting sites. But they are flying earlier in the year, as a result of a warmer climate and a changing agricultural landscape, according to new research.
Published Deforestation in the tropics linked to a reduction in rainfall
(via sciencedaily.com) Deforestation is resulting in reduced rainfall across large parts of the tropics, according to new research. People living in tropical forest communities have often complained that the climate gets hotter and drier once trees are cleared but until now, scientists have not been able to identify a clear link between the loss of tree cover and a decline in rainfall.
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 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 Flower power: The role of ants in forest regeneration
(via sciencedaily.com) Ants play a key role in forest regeneration, according to a new article.
Published Australia's rarest bird of prey disappearing at alarming rate
(via sciencedaily.com) Australia's rarest bird of prey -- the red goshawk -- is facing extinction, with Cape York Peninsula now the only place in Queensland known to support breeding populations.
Published Rare insect found in Arkansas sets historic record, prompts mystery
(via sciencedaily.com) A giant insect found in Arkansas has set historic records. The Polystoechotes punctata or giant lacewing is the first of its kind recorded in eastern North America in over 50 years. The giant lacewing was formerly widespread across North America, but was mysteriously extirpated from eastern North America by the 1950s. This discovery suggests there may be relic populations of this large insect yet to be discovered.
Published New material may offer key to solving quantum computing issue
(via sciencedaily.com) A new form of heterostructure of layered two-dimensional (2D) materials may enable quantum computing to overcome key barriers to its widespread application, according to an international team of researchers.
Published Breakthrough in tin-vacancy centers for quantum network applications
(via sciencedaily.com) Tin-vacancy (Sn-V) centers in diamond have the potential to function as quantum nodes in quantum networks to transmit information. However, they pose limitations while showing optical properties to generate quantum entanglement. Researchers have now overcome this challenge by generating stable Sn-V centers that can produce photons with nearly identical frequencies and linewidths, paving the way for the advancement of Sn-V centers as a quantum-light matter interface.
Published New study reveals biodiversity loss drove ecological collapse after the 'Great Dying'
(via sciencedaily.com) By exploring the stability and collapse of marine ecosystems during the Permian-Triassic mass extinction, researchers gain insights into modern biodiversity crisis.
Published Marine heatwaves decimate sea urchins, molluscs and more at Rottnest
(via sciencedaily.com) Researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as molluscs and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 per cent between 2007 and 2021.
Published Effort to help pollinators shows successes, limitations
(via sciencedaily.com) A three-year effort to conserve bee populations by introducing pollinator habitat in North Carolina agricultural areas showed some positive effects, as bee abundance and diversity increased in the studied areas. But results of a study examining the program's effectiveness also showed that the quality of the habitat played a key role in these positive effects, and that habitat quality could be impacted by the way the areas are maintained over time.
Published A labyrinth lake provides surprising benefits for an endangered seal
(via sciencedaily.com) The endangered Saimaa ringed seal is an Ice Age relict living in the highly labyrinthine Lake Saimaa, Finland. The newly published work shows that although individual seals have greatly reduced genetic variation, the loss of variation has been complementary, preserving the adaptive potential of the whole population.
