Published Quantum pumping in molecular junctions
(via sciencedaily.com) Original source Researchers have developed a new theoretical modelling technique that could potentially be used in the development of switches or amplifiers in molecular electronics.
Published Scientists map DNA of Lyme disease bacteria
(via sciencedaily.com) Original source Researchers have produced a genetic analysis of Lyme disease bacteria that may pave the way for improved diagnosis, treatment, and prevention of the tick-borne ailment.
Published Advancing modular quantum information processing
(via sciencedaily.com) Original source A team of physicists envisions a modular system for scaling quantum processors with a flexible way of linking qubits over long distances to enable them to work in concert to perform quantum operations. The ability to carry out such correlated or 'entangling' operations between linked qubits is the basis of the enhanced power quantum computing holds compared with current computers.
Published Physicists throw world's smallest disco party
(via sciencedaily.com) Original source A new milestone has been set for levitated optomechanics as a group of scientists observed the Berry phase of electron spins in nano-sized diamonds levitated in vacuum.
Published How bread dough gave rise to civilization
(via sciencedaily.com) Original source A major international study has explained how bread wheat helped to transform the ancient world on its path to becoming the iconic crop that today helps sustain a global population of eight billion.
Published Decoding the world's largest animal genome
(via sciencedaily.com) Original source Scientists have sequenced the largest genome of all animals, the lungfish genome. Their data help to explain how the fish-ancestors of today's land vertebrates were able to conquer land.
Published Surprising insight into cancer comes from unique plant species that find different solutions to evolutionary challenges
(via sciencedaily.com) Original source A study has shown that different plant species tackle the same evolutionary hurdle in different ways, and the findings may give insight into aggressive forms of cancer.
Published Rewriting the evolutionary history of critical components of the nervous system
(via sciencedaily.com) Original source A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the Shaker family of ion channels were present in microscopic single cell organisms well before the common ancestor of all animals and thus before the origin of the nervous system.
Published The mother of all motion sensors
(via sciencedaily.com) Original source Researchers have used silicon photonic microchip components to perform a quantum sensing technique called atom interferometry, an ultra-precise way of measuring acceleration. It is the latest milestone toward developing a kind of quantum compass for navigation when GPS signals are unavailable.
Published Taking a 'one in a million' shot to tackle dopamine-linked brain disorders
(via sciencedaily.com) Original source With the help of a tiny, transparent worm called Caenorhabditis elegans, researchers have identified novel players in dopamine signaling by taking advantage of a powerful platform generated via the Million Mutation Project (MMP) for the rapid identification of mutant genes based on their functional impact. They can seek insights from simpler organisms whose genes bear striking similarity to those found in humans and where opportunities for genetic insights to disease can be pursued more efficiently and inexpensively.
Published Mix of factors prompts owl monkeys to leave their parents
(via sciencedaily.com) Original source There comes a point in the lives of young owl monkeys when they leave their parents and strike out on their own to find a mate. In a new study of a wild population of Azara's owl monkeys in northern Argentina, researchers reveal that a combination of social and ecological factors influences when these tree-dwelling monkeys peel away from their parents and siblings. According to their findings -- which were based on 25 years of genetic and demographic data for several generations of owl monkeys, covering more than 330 individuals -- none of the individuals, regardless of their sex, reproduced in the same group where they were born. In all cases, the researchers found, the animals either departed from their natal group or died before reproducing.
Published Lemurs use long-term memory, smell, and social cues to find food
(via sciencedaily.com) Original source How do foraging animals find their food? A new study shows that lemurs use smell, social cues, and long-term memory to locate hidden fruit -- a combination of factors that may have deep evolutionary roots.
Published X-ray imagery of vibrating diamond opens avenues for quantum sensing
(via sciencedaily.com) Original source Scientists at three research institutions capture the pulsing motion of atoms in diamond, uncovering the relationship between the diamond's strain and the behavior of the quantum information hosted within.
Published Living with a killer: How an unlikely mantis shrimp-clam association violates a biological principle
(via sciencedaily.com) Original source When clams gamble on living with a killer, sometimes their luck may run out, according to a new study.
Published Researchers find gene which determines marsupial fur color
(via sciencedaily.com) Original source Fur is a defining characteristic of mammals, coming in a wide variety of colors and patterns -- thanks to a world-first study, we now know which genes make a marsupial's coat black or grey.
Published First measurement of electron- and muon-neutrino interaction rates at the highest energy ever detected from an artificial source
(via sciencedaily.com) Original source Understanding neutrino interactions is crucial for obtaining a complete picture of particle physics and the universe. To date, neutrino interaction cross sections have not been measured at high energy above some hundred gigaelectronvolts at particle colliders. Now, researchers have obtained the first direct observation of electron and muon neutrino interactions in the Teraelectronvolt range at CERN's Large Hadron Collider, using the FASER detector. This study marks a significant step for particle physics research.
Published Cold antimatter for quantum state-resolved precision measurements
(via sciencedaily.com) Original source Why does the universe contain matter and (virtually) no antimatter? Scientists have achieved an experimental breakthrough in this context. It can contribute to measuring the mass and magnetic moment of antiprotons more precisely than ever before -- and thus identify possible matter-antimatter asymmetries. They have developed a trap, which can cool individual antiprotons much more rapidly than in the past.
Published Fossil shows how penguins' wings evolved
(via sciencedaily.com) Original source A tiny fossil penguin plays a huge role in the evolutionary history of the bird, an international study shows.
Published Climate anomalies may play a major role in driving cholera pandemics
(via sciencedaily.com) Original source New research suggests that an El Nino event may have aided the establishment and spread of a novel cholera strain during an early 20th-century pandemic, supporting the idea that climate anomalies could create opportunities for the emergence of new cholera strains.
Published Half a billion-year-old spiny slug reveals the origins of mollusks
(via sciencedaily.com) Original source Exceptional fossils with preserved soft parts reveal that the earliest mollusks were flat, armored slugs without shells. The new species, Shishania aculeata, was covered with hollow, organic, cone-shaped spines. The fossils preserve exceptionally rare detailed features which reveal that these spines were produced using a sophisticated secretion system that is shared with annelids (earthworms and relatives).
