Published Island birds more adaptable than previously thought
(via sciencedaily.com) Original source The researchers found that birds were more evolutionarily similar on smaller, more isolated islands than on larger, less remote places. The team had expected to find that forested areas had more numerous and more varied species of birds compared to farmland areas. But they were surprised to find that the opposite was true: Areas with farms and human settlements had more species of birds and greater diversity than forested areas.
Published Transformation of ocean management is underway
(via sciencedaily.com) Original source Despite its benefits and recognition as a keystone practice of ocean stewardship and conservation, adoption of ecosystem-based management has been slow to take hold. To support this change in ocean management, a group of researchers and practitioners investigated the global progress of marine EBM initiatives.
Published Rapid oyster reef restoration gives hope for repairing the sea
(via sciencedaily.com) Original source After a century of functional extinction on the Australian mainland, a Flat oyster reef has been successfully restored along a metropolitan Adelaide coastline.
Published Saturated soils could impact survival of young trees planted to address climate change
(via sciencedaily.com) Original source New research has looked into the potential effects of increased rainfall in regions being earmarked for expansion of temperate rainforests. Amid global calls for more trees to be planted as part of efforts to combat climate change, this study highlights the importance of factoring in soil conditions when looking at where and how to create the temperate rainforests of the future.
Published Limited adaptability makes freshwater bacteria vulnerable to climate change
(via sciencedaily.com) Original source Freshwater bacteria with small genomes frequently undergo prolonged periods of adaptive stagnation. Based on genomic analyses of samples from European lakes, researchers uncovered specific evolutionary strategies that shape these bacteria's lifestyles. Understanding the evolutionary dynamics of aquatic microbial communities is key to safeguarding ecosystem services.
Published New super-pure silicon chip opens path to powerful quantum computers
(via sciencedaily.com) Original source Researchers have invented a breakthrough technique for manufacturing highly purified silicon that brings powerful quantum computers a big step closer.
Published Experiment opens door for millions of qubits on one chip
(via sciencedaily.com) Original source Researchers have achieved the first controllable interaction between two hole spin qubits in a conventional silicon transistor. The breakthrough opens up the possibility of integrating millions of these qubits on a single chip using mature manufacturing processes.
Published New quantum sensing scheme could lead to enhanced high-precision nanoscopic techniques
(via sciencedaily.com) Original source Researchers have unveiled a quantum sensing scheme that achieves the pinnacle of quantum sensitivity in measuring the transverse displacement between two interfering photons.
Published Stony coral tissue loss disease is shifting the ecological balance of Caribbean reefs
(via sciencedaily.com) Original source A new study shows stony coral tissue loss disease is causing drastic changes in the Caribbean's population of corals, which is sure to disrupt the delicate balance of the ecosystem and threaten marine biodiversity and coastal economies.
Published Physicists arrange atoms in extremely close proximity
(via sciencedaily.com) Original source Physicists developed a technique to arrange atoms in much closer proximity than previously possible, down to 50 nanometers. The group plans to use the method to manipulate atoms into configurations that could generate the first purely magnetic quantum gate -- a key building block for a new type of quantum computer.
Published Scientists test for quantum nature of gravity
(via sciencedaily.com) Original source A new study reports on a deep new probe into the interface between the theories of gravity and quantum mechanics, using ultra-high energy neutrino particles detected by a particle detector set deep into the Antarctic glacier at the south pole.
Published Significant new discovery in teleportation research -- Noise can improve the quality of quantum teleportation
(via sciencedaily.com) Original source Researchers succeeded in conducting an almost perfect quantum teleportation despite the presence of noise that usually disrupts the transfer of quantum state.
Published To bend the curve of biodiversity loss, nature recovery must be integrated across all sectors
(via sciencedaily.com) Original source The alarming rates of biodiversity loss worldwide have made clear that the classical way of governing biodiversity recovery based on protected areas and programs for the protection of endangered species is not enough. To tackle this, almost 200 countries committed to the active 'mainstreaming' or integration of biodiversity targets into policies and plans across relevant sectors. However, research suggests that this has until now been largely ineffective due to non-binding commitments, vaguely formulated targets, 'add-on' biodiversity initiatives, and too few resources. 'Top down regulation is also needed,' say the authors.
Published Physicists build new device that is foundation for quantum computing
(via sciencedaily.com) Original source Scientists have adapted a device called a microwave circulator for use in quantum computers, allowing them for the first time to precisely tune the exact degree of nonreciprocity between a qubit, the fundamental unit of quantum computing, and a microwave-resonant cavity. The ability to precisely tune the degree of nonreciprocity is an important tool to have in quantum information processing. In doing so, the team derived a general and widely applicable theory that simplifies and expands upon older understandings of nonreciprocity so that future work on similar topics can take advantage of the team's model, even when using different components and platforms.
Published Researchers unlock potential of 2D magnetic devices for future computing
(via sciencedaily.com) Original source A research team has created an innovative method to control tiny magnetic states within ultrathin, two-dimensional van der Waals magnets -- a process akin to how flipping a light switch controls a bulb.
Published Scientists show that there is indeed an 'entropy' of quantum entanglement
(via sciencedaily.com) Original source Scientists have shown, through probabilistic calculations, that there is indeed, as had been hypothesized, a rule of 'entropy' for the phenomenon of quantum entanglement. This finding could help drive a better understanding of quantum entanglement, which is a key resource that underlies much of the power of future quantum computers.
Published Big data reveals true climate impact of worldwide air travel
(via sciencedaily.com) Original source A new study that looked at nearly 40 million flights in 2019 calculated the greenhouse gas emissions from air travel for essentially every country on the planet. At 911 million tons, the total emissions from aviation are 50 per cent higher than the 604 million tons reported to the United Nations for that year.
Published How can forests be reforested in a climate-friendly way?
(via sciencedaily.com) Original source Europe's forests have already been severely affected by climate change. Thousands of hectares of trees have already died due to drought and bark beetles. Scientists have now investigated which trees can be used for reforestation. Their findings: only a few tree species are fit for the future, such as English oak in the UK. However, mixed forests are important for the survival of forests, otherwise the forest ecosystem as a whole could be weakened.
Published The end of the quantum tunnel
(via sciencedaily.com) Original source Quantum mechanical effects such as radioactive decay, or more generally: 'tunneling', display intriguing mathematical patterns. Researchers now show that a 40-year-old mathematical discovery can be used to fully encode and understand this structure.
Published From disorder to order: Flocking birds and 'spinning' particles
(via sciencedaily.com) Original source Researchers have demonstrated that ferromagnetism, an ordered state of atoms, can be induced by increasing particle motility and that repulsive forces between atoms are sufficient to maintain it. The discovery not only extends the concept of active matter to quantum systems but also contributes to the development of novel technologies that rely on the magnetic properties of particles, such as magnetic memory and quantum computing.
