Published Whales give up singing to fight for love
(via sciencedaily.com) Male whales along Australia's eastern seaboard are giving up singing to attract a mate, switching instead to fighting their male competition.
Published Engineers discover a new way to control atomic nuclei as 'qubits'
(via sciencedaily.com) Researchers propose a new approach to making qubits, the basic units in quantum computing, and controlling them to read and write data. The method is based on measuring and controlling the spins of atomic nuclei, using beams of light from two lasers of slightly different colors.
Published Proposed quantum device may succinctly realize emergent particles such as the Fibonacci anyon
(via sciencedaily.com) Tenacity has taken a roadblock and turned it into a possible route to the development of quantum computing.
Published How the fastest fish hunts its prey
(via sciencedaily.com) Scientists have designed a novel electronic tag package incorporating high-tech sensors and a video camera in order to document a detailed view of exactly how sailfish behave and hunt once they are on their own and out of view of the surface.
Published Securing supply chains with quantum computing
(via sciencedaily.com) New research in quantum computing is moving science closer to being able to overcome supply-chain challenges and restore global security during future periods of unrest.
Published Whale warning as clock ticks towards deep-sea mining
(via sciencedaily.com) Seabed mining could soon begin in the deep ocean -- but the potential impact on animals including whales is unknown, researchers have warned.
Published When the light is neither 'on' nor 'off' in the nanoworld
(via sciencedaily.com) Scientists detect the quantum properties of collective optical-electronic oscillations on the nanoscale. The results could contribute to the development of novel computer chips.
Published Coral reefs in the Eastern Pacific could survive into the 2060s
(via sciencedaily.com) Scientists found that some reefs in the tropical Pacific Ocean could maintain high coral cover into the second half of this century by shuffling the symbiotic algae they host. The findings offer a ray of hope in an often-dire picture of the future of coral reefs worldwide.
Published Biodiversity engine for fishes: Shifting water depth
(via sciencedaily.com) Fish, the most biodiverse vertebrates in the animal kingdom, present evolutionary biologists a conundrum: The greatest species richness is found in the world's tropical waters, yet the fish groups that generate new species most rapidly inhabit colder climates at higher latitudes. A new study helps to explain this paradox. The researchers discovered that the ability of fish in temperate and polar ecosystems to transition back and forth from shallow to deep water triggers species diversification. Their findings suggest that as climate change warms the oceans at higher latitudes, it will impede the evolution of fish species.
Published Due to their feed, chicken and farmed salmon have remarkably similar environmental footprints
(via sciencedaily.com) We love our chicken. We love our salmon. Thanks to how we farm these two popular proteins, their environmental footprints are surprisingly similar.
Published Researchers detail never-before-seen properties in a family of superconducting Kagome metals
(via sciencedaily.com) Researchers have used an innovative new strategy combining nuclear magnetic resonance imaging and a quantum modeling theory to describe the microscopic structure of Kagome superconductor RbV3Sb5 at 103 degrees Kelvin, which is equivalent to about 275 degrees below 0 degrees Fahrenheit.
Published 'It's me!' Fish recognizes itself in photographs, say scientists
(via sciencedaily.com) Original source Scientists have demonstrated that fish think 'it's me' when they see themselves in a picture. The researchers found that the determining factor was not the fish seeing their own body but seeing their face.
Published Fossil discovery reveals complex ecosystems existed on Earth much earlier than previously thought
(via sciencedaily.com) Original source About 250 million years ago, the Permian-Triassic mass extinction killed over 80 per cent of the planet's species. In the aftermath, scientists believe that life on earth was dominated by simple species for up to 10 million years before more complex ecosystems could evolve. Now this longstanding theory is being challenged by a team of international researchers.
Published Scientists boost quantum signals while reducing noise
(via sciencedaily.com) Researchers have developed a special type of amplifier that uses a technique known as squeezing to amplify quantum signals by a factor of 100 while reducing the noise that is inherent in quantum systems by an order of magnitude. Their device is the first to demonstrate squeezing over a broad frequency bandwidth of 1.75 gigahertz, nearly two orders of magnitude higher than other architectures.
Published The cod population off the coast of Sweden is not extinct
(via sciencedaily.com) Original source Through DNA analyses, researchers have identified that there are still juvenile coastal cod off the west coast of Sweden. However, it is still difficult to find any mature adult cod in the area.
Published Marine reserves unlikely to restore marine ecosystems
(via sciencedaily.com) Protected marine areas are one of the essential tools for the conservation of natural resources affected by human impact -- mainly fishing --, but, are they enough to recover the functioning of these systems? A study now highlights the limitations of marine reserves in restoring food webs to their pristine state prior to the impact of intensive fishing.
Published Scientists make major breakthrough in developing practical quantum computers that can solve big challenges of our time
(via sciencedaily.com) Researchers have demonstrated that quantum bits (qubits) can directly transfer between quantum computer microchips and demonstrated this with record-breaking connection speed and accuracy. This breakthrough resolves a major challenge in building quantum computers large and powerful enough to tackle complex problems that are of critical importance to society.
Published Surprises in sea turtle genes could help them adapt to a rapidly changing world
(via sciencedaily.com) Around 100 million years ago, a group of land-dwelling turtles took to the oceans, eventually evolving into the sea turtles that we know today. However, the genetic foundations that have enabled them to thrive in oceans throughout the world have remained largely unknown.
Published Entangled atoms cross quantum network from one lab to another
(via sciencedaily.com) Trapped ions have previously only been entangled in one and the same laboratory. Now, teams have entangled two ions over a distance of 230 meters. The nodes of this network were housed in two labs at the Campus Technik to the west of Innsbruck, Austria. The experiment shows that trapped ions are a promising platform for future quantum networks that span cities and eventually continents.
Published Researchers devise a new path toward 'quantum light'
(via sciencedaily.com) Researchers have theorized a new mechanism to generate high-energy 'quantum light', which could be used to investigate new properties of matter at the atomic scale.
