Published How the Amazon rainforest is likely to cope with the effect of future drought



A major collaboration involving 80 scientists from Europe and South America has identified the regions of the Amazon rainforest where trees are most likely to face the greatest risk from drier conditions brought about by climate change. Based on the analysis, the scientists predict trees in the western and southern Amazon face the greatest risk of dying. They also warn that previous scientific investigations may have underestimated the impact of drought on the rainforest because those studies focused on the central-eastern part of the forest, which is the least vulnerable to drought.
Published Prehistoric scat reveals 'Waves' of extinction in Colombia



Fungal spores found in dung have revealed that large animals went extinct in two 'waves' in the Colombian Andes.
Published Woodpecker guides post-fire forest management



What's good for the Black-backed Woodpecker is good for restoration of burned California forests. The birds' unique relationship with fire underpins the latest research into improved post-fire management. A study describes a new tool that factors in how fires burn into forest management decisions and turns science into action for wildlife conservation.
Published Ocean ecosystem: Mixotrophic microorganisms play key role



Researchers have identified a previously unknown group of bacteria, called UBA868, as key players in the energy cycle of the deep ocean. They are significantly involved in the biogeochemical cycle in the marine layer between 200 and 1000 meters.
Published Scientists have full state of a quantum liquid down cold



A team of physicists has illuminated certain properties of quantum systems by observing how their fluctuations spread over time. The research offers an intricate understanding of a complex phenomenon that is foundational to quantum computing.
Published Colorado's spicy ancient history of chili peppers



Recently identified chili pepper fossils from Boulder and Denver museums challenge millions of years of global tomato evolutionary history. Now, that's some spicy science!
Published 360-million-year-old Irish fossil provides oldest evidence of plant self-defense in wood



Scientists have discovered the oldest evidence of plant self-defense in wood in a 360-million-year-old fossil from south-eastern Ireland. Plants can protect their wood from infection and water loss by forming special structures called 'tyloses'. These prevent bacterial and fungal pathogens from getting into the heartwood of living trees and damaging it. However, it was not previously known how early in the evolution of plants woody species became capable of forming such defenses. Published today in Nature Plants is the oldest evidence of tylosis formation from Late Devonian (360-million-year-old) fossil wood from the Hook Head Peninsula area, Co. Wexford, Ireland.
Published Newly sequenced hornet genomes could help explain invasion success



The genomes of two hornet species, the European hornet and the Asian hornet (or yellow-legged hornet) have been sequenced.
Published The climate crisis and biodiversity crisis can't be approached as two separate things



Anthropogenic climate change has, together with the intensive use and destruction of natural ecosystems through agriculture, fishing and industry, sparked an unprecedented loss of biodiversity that continues to worsen. In this regard, the climate crisis and biodiversity crisis are often viewed as two separate catastrophes. An international team of researchers calls for adopting a new perspective.
Published Biologists discover bees to be brew masters of the insect world



Scientists have made a remarkable discovery about cellophane bees -- their microbiomes are some of the most fermentative known from the insect world. These bees, which are named for their use of cellophane-like materials to line their subterranean nests, are known for their fascinating behaviors and their important ecological roles as pollinators. Now, researchers have uncovered another aspect of their biology that makes them even more intriguing.
Published Quantum entanglement could make accelerometers and dark matter sensors more accurate



The 'spooky action at a distance' that once unnerved Einstein may be on its way to being as pedestrian as the gyroscopes that currently measure acceleration in smartphones.
Published Two qudits fully entangled



Recently quantum computers started to work with more than just the zeros and ones we know from classical computers. Now a team demonstrates a way to efficiently create entanglement of such high-dimensional systems to enable more powerful calculations.
Published Quantum computer applied to chemistry



There are high expectations that quantum computers may deliver revolutionary new possibilities for simulating chemical processes. This could have a major impact on everything from the development of new pharmaceuticals to new materials. Researchers have now used a quantum computer to undertake calculations within a real-life case in chemistry.
Published Embracing variations: Physicists analyze noise in Lambda-type quantum memory



In the future, communications networks and computers will use information stored in objects governed by the microscopic laws of quantum mechanics. This capability can potentially underpin communication with greatly enhanced security and computers with unprecedented power. A vital component of these technologies will be memory devices capable of storing quantum information to be retrieved at will.
Published Companies' zero-deforestation commitments have potential to halve cattle-driven deforestation in Brazilian Amazon



Study shows better adoption and implementation of company supply chain policies for Brazilian beef and leather could significantly reduce carbon emissions.
Published Nature's chefs: Scientists propose food-making as means of understanding species interactions



An interdisciplinary group of researchers is proposing a new way to think of some interactions between species, classifying a variety of plants, animals and fungi as 'nature's chefs.' Specifically, nature's chefs are organisms that provide food -- or the illusion of food -- to other organisms. The concept offers a new perspective on species interactions, which can inform how people think about food across the tree of life as well as disparate research disciplines.
Published Rock, paper, scissors: Searching for stronger nonlocality using quantum computers



In the quantum world particles can instantaneously know about each other's state, even when separated by large distances. This is known as nonlocality. Now, A research group has produced some interesting findings on the Hardy nonlocality that have important ramifications for understanding quantum mechanics and its potential applications in communications.
Published Long-distance quantum teleportation enabled by multiplexed quantum memories



Researchers report having achieved quantum teleportation from a photon to a solid-state qubit over a distance of 1km, with a novel approach using multiplexed quantum memories.
Published A team creates 'quantum composites' for various electrical and optical innovations



A team has shown in the laboratory the unique and practical function of newly created materials, which they called quantum composites, that may advance electrical, optical, and computer technologies.
Published The diversity of present tree species is shaped by climate change in the last 21,000 years



A new global survey of 1000 forest areas shows how climate change since the peak of the last ice age has had a major impact on the diversity and distribution of tree species we see today. The results can help us predict how ecosystems will react to future changes, thus having an impact on conservation management around the globe.
