Published 1,000 atomic qubits and rising
(via sciencedaily.com) Original source Making quantum systems more scalable is one of the key requirements for the further development of quantum computers because the advantages they offer become increasingly evident as the systems are scaled up. Researchers have recently taken a decisive step towards achieving this goal.
Published How is deforested land in Africa used?
(via sciencedaily.com) Original source Africa's forested areas -- an estimated 14 % of the global forest area -- are continuing to decline at an increasing rate -- mostly because of human activities to convert forest land for economic purposes. As natural forests are important CO2 and biodiversity reservoirs, this development has a significant impact on climate change and effects the integrity of nature.
Published Reforestation programs could threaten vast area of tropical grasslands
(via sciencedaily.com) Original source New research reveals the scale of inappropriate reforestation projects across Africa. A new study reveals that an area the size of France is threatened by forest restoration initiatives, such as the AFR100 initiative (African Forest Landscape Restoration Initiative), due to inappropriate restoration in the form of tree-planting.
Published Big new idea introduced with the help of tiny plankton
(via sciencedaily.com) Original source A new model bridges the rules of life at the individual scale and the ecosystem level, which could open new avenues of exploration in ecology, global change biology, and ultimately ecosystem management.
Published A lighthouse in the Gobi desert
(via sciencedaily.com) Original source A new study explores the weight great fossil sites have on our understanding of evolutionary relationships between fossil groups and quantified the power these sites have on our understanding of evolutionary history. Surprisingly, the authors discovered that the wind-swept sand deposits of the Late Cretaceous Gobi Desert's extraordinarily diverse and well-preserved fossil lizard record shapes our understanding of their evolutionary history more than any other site on the planet.
Published A new optical metamaterial makes true one-way glass possible
(via sciencedaily.com) Original source Researchers have discovered how to make an optical metamaterial that would underpin a variety of new technologies.
Published Love songs lead scientists to new populations of skywalker gibbons in Myanmar
(via sciencedaily.com) Original source The love songs of the Skywalker gibbon alerted scientists to a new population of the endangered primate in Myanmar.
Published Is the Amazon forest approaching a tipping point?
(via sciencedaily.com) Original source Global warming may be interacting with regional rainfall and deforestation to accelerate forest loss in the Amazon, pushing it towards partial or total collapse. New research has identified the potential thresholds of these stressors, showing where their combined effects could produce a 'tipping point' -- in which the forest is so fragile that just a small disturbance could cause an abrupt shift in the state of the ecosystem.
Published A 'quantum leap' at room temperature
(via sciencedaily.com) Original source Scientists have achieved a milestone by controlling quantum phenomena at room temperature.
Published A century of reforestation helped keep the eastern US cool
(via sciencedaily.com) Original source Widespread 20th-century reforestation in the eastern United States helped counter rising temperatures due to climate change, according to new research. The authors highlight the potential of forests as regional climate adaptation tools, which are needed along with a decrease in carbon emissions.
Published Australia's most at-risk bird species share some common traits
(via sciencedaily.com) Original source Australian birds that live on islands are among the species most at risk of extinction, a first-of-its-kind study has shown. Australia has over 750 native bird species. But many of them are facing an uncertain future.
Published How ancient sea creatures can inform soft robotics
(via sciencedaily.com) Original source Fossils of a marine animal that lived 500 million years ago, combined with computer simulations, informed the design of a new soft robot.
Published The hidden rule for flight feathers -- and how it could reveal which dinosaurs could fly
(via sciencedaily.com) Original source Scientists examined hundreds of birds in museum collections and discovered a suite of feather characteristics that all flying birds have in common. These 'rules' provide clues as to how the dinosaur ancestors of modern birds first evolved the ability to fly, and which dinosaurs were capable of flight.
Published Global deforestation leads to more mercury pollution
(via sciencedaily.com) Original source Researchers find deforestation accounts for about 10 percent of global human-made mercury emissions. While it cannot be the only solution, they suggest reforestation could increase global mercury uptake by about 5 percent.
Published Five dazzling new species of eyelash vipers discovered in Colombia and Ecuador
(via sciencedaily.com) Original source Scientists have discovered five dazzling new species of eyelash vipers in the jungles and cloud forests of Colombia and Ecuador.
Published Researchers show classical computers can keep up with, and surpass, their quantum counterparts
(via sciencedaily.com) Original source A team of scientists has devised means for classical computing to mimic a quantum computing with far fewer resources than previously thought. The scientists' results show that classical computing can be reconfigured to perform faster and more accurate calculations than state-of-the-art quantum computers.
Published Alien invasion: Non-native earthworms threaten ecosystems
(via sciencedaily.com) Original source Analysis reveals imported earthworm species have colonized large swaths of North America, and represent a largely overlooked threat to native ecosystems. The researchers warn of the need to better understand and manage the invaders in our midst.
Published New fossil site of worldwide importance uncovered in southern France
(via sciencedaily.com) Original source Nearly 400 exceptionally well-preserved fossils dating back 470 million years have been discovered in the south of France by two amateur paleontologists. The discovery provides unprecedented information on the polar ecosystems of the Ordovician period.
Published Friend or foe? Ancient partnership between moss and fungi
(via sciencedaily.com) Original source Researchers have shed new light on the ancient relationship between moss and fungi. They discovered that intricate moss-fungi interactions often depended on a third variable -- the presence of endobacteria within the fungi themselves.
Published Replacing animal-based foods with alternative proteins would unlock land for carbon removal
(via sciencedaily.com) Original source Researchers report that replacing 50% of animal products with alternative proteins by 2050 could free up enough agricultural land to generate renewable energy equivalent in volume to today's coal-generated power while simultaneously removing substantial CO2 from the atmosphere.
