Published Making the invisible, visible: New method makes mid-infrared light detectable at room temperature
(via sciencedaily.com) Scientists have developed a new method for detecting mid-infrared (MIR) light at room temperature using quantum systems.
Published Scientists use quantum device to slow down simulated chemical reaction 100 billion times
(via sciencedaily.com) Using a trapped-ion quantum computer, the research team witnessed the interference pattern of a single atom caused by a 'conical intersection'. Conical intersections are known throughout chemistry and are vital to rapid photo-chemical processes such as light harvesting in human vision or photosynthesis.
Published Researcher finds inspiration from spider webs and beetles to harvest fresh water from thin air
(via sciencedaily.com) A team of researchers is designing novel systems to capture water vapor in the air and turn it into liquid. They have developed sponges or membranes with a large surface area that continually capture moisture from their surrounding environment.
Published Soils forming on the branches of trees are an overlooked forest habitat
(via sciencedaily.com) A study on 'canopy soils' on old trees in Costa Rica shows they are important habitats and carbon stores that cannot easily be replaced.
Published New quantum device generates single photons and encodes information
(via sciencedaily.com) A new approach to quantum light emitters generates a stream of circularly polarized single photons, or particles of light, that may be useful for a range of quantum information and communication applications. A team stacked two different, atomically thin materials to realize this chiral quantum light source.
Published Millions of carbon credits are generated by overestimating forest preservation, study finds
(via sciencedaily.com) Original source Study analyses 18 major carbon offset projects, and compares their conservation claims with matched sites that offer a real-world benchmark for deforestation levels. Over 60 million carbon credits came from projects that barely reduced deforestation, if at all. Of a potential 89 million credits from these offset schemes, only 5.4 million (6%) were linked to additional carbon reductions through preserved forest.
Published Do measurements produce the reality they show us?
(via sciencedaily.com) The measurement values determined in sufficiently precise measurements of physical systems will vary based on the relation between the past and the future of a system determined by its interactions with the meter. This finding may explain why quantum experiments often produce paradoxical results that can contradict our common-sense idea of physical reality.
Published National parks support wildlife inside and outside their borders
(via sciencedaily.com) Fresh research suggests that national parks enhance bird diversity inside their borders. Large parks also support higher diversity of both birds and mammals in nearby unprotected areas.
Published Ice-free preservation method holds promise to protect reefs
(via sciencedaily.com) An interdisciplinary team of researchers demonstrated that coral can be preserved through a new technique called isochoric vitrification. This process takes the selected coral fragments through the stages of cryopreservation and subsequent revival.
Published Deforestation limits nesting habitat for cavity-nesting birds
(via sciencedaily.com) A new study of cavity-nesting birds in Ecuador shows the influence of deforestation on their habitat and reproductive success. Nest boxes could help.
Published Researchers unearth a new process by which algae pass on nurtrients to their coral host
(via sciencedaily.com) Researchers have identified a new pathway by which sugar is released by symbiotic algae. This pathway involves the largely overlooked cell wall, showing that this structure not only protects the cell but plays an important role in symbiosis and carbon circulation in the ocean.
Published Research group detects a quantum entanglement wave for the first time using real-space measurements
(via sciencedaily.com) A team has created an artificial quantum magnet featuring a quasiparticle made of entangled electrons, the triplon.
Published Tree mortality in the Black Forest on the rise -- climate change a key driver
(via sciencedaily.com) Original source Climate impacts such as dry, hot summers reduce the growth and increase the mortality of trees in the Black Forest because they negatively influence the climatic water balance, i.e., the difference between precipitation and potential evapotranspiration. That is the central finding of a long-term study of the influence of climate and climate change on trees in the Black Forest.
Published Scientists develop fermionic quantum processor
(via sciencedaily.com) Researchers have designed a new type of quantum computer that uses fermionic atoms to simulate complex physical systems. The processor uses programmable neutral atom arrays and is capable of simulating fermionic models in a hardware-efficient manner using fermionic gates. The team demonstrated how the new quantum processor can efficiently simulate fermionic models from quantum chemistry and particle physics.
Published Buffalo slaughter left lasting impact on Indigenous peoples
(via sciencedaily.com) Original source The near extinction of the North American bison in the late 1800s caused a devastating, lasting economic shock to Indigenous peoples whose lives depended on the animals, an economic study finds.
Published Biodiversity protects against invasions of non-native tree species
(via sciencedaily.com) Researchers combined human and ecological factors to analyze the global scale of non-native tree species invasions. Human activity in hotspots of global trade, such as maritime ports, is linked to an increased likelihood of non-native tree species invasions. However, a high diversity of native tree species can help to curb the intensity of such invasions.
Published Vegetarian diet of corals explains age-old mystery dating back to Darwin
(via sciencedaily.com) Original source A new study has revealed why coral reefs can thrive in seemingly nutrient poor water, a phenomenon that has fascinated scientists since Charles Darwin.
Published Mapping methane emissions from rivers around globe reveals surprising sources
(via sciencedaily.com) Original source A new study finds rivers and streams at higher latitudes contributing as much methane, a potent greenhouse gas, to the atmosphere as warmer waters in the tropics. The surrounding habitat, not temperature, is the important driver of methane emissions. The findings could improve methane estimates and models of climate change, and point to land-management changes and restoration opportunities that can reduce the amount of methane escaping into the atmosphere.
Published Fire, disease threatening sanctuary plants for Australian wildlife
(via sciencedaily.com) Original source New research has revealed Australia's iconic grasstrees -- known as 'yaccas' -- play a critical role in protecting wildlife from deadly weather extremes, thereby ensuring their survival. But the grasses themselves are under threat due to back burning, clearing and disease.
Published Hundreds of Andean bird species at risk due to deforestation: New research shows how to protect them
(via sciencedaily.com) Original source Birds native to the tropical Andes are threatened by increasing agricultural development in the region. A new study combines a meta-analysis of papers on birds across the Andes with five years of fieldwork in Peru, revealing that open farmlands result in up to a 60% decline in the number of species in an area. The study documents how specific species are affected and provides tailored guidance for conservationists trying to protect them.
