Published Keeping time with an atomic nucleus
(via sciencedaily.com) Original source Nuclear clocks could allow scientists to probe the fundamental forces of the universe in the future. Researchers have made a crucial advance in this area as part of an international collaboration.
Published Quantum scientists accurately measure power levels one trillion times lower than usual
(via sciencedaily.com) Original source Scientists have developed a nanodevice that can measure the absolute power of microwave radiation down to the femtowatt level at ultra-low temperatures -- a scale trillion times lower than routinely used in verifiable power measurements. The device has the potential to significantly advance microwave measurements in quantum technology.
Published Weevils, long-nosed beetles, are unsung heroes of pollination
(via sciencedaily.com) Original source Some of nature's most diverse pollinators often go unnoticed, even by scientists: long-snouted beetles called weevils. A new study provides a deep dive into the more than 600 species of weevils, including ones whose entire life cycles are interwoven with a specific plant that they help pollinate.
Published Iron-rich rocks unlock new insights into Earth's planetary history
(via sciencedaily.com) Original source A new study suggests iron-rich ancient sediments may have helped cause some of the largest volcanic events in the planet's history.
Published Deep sea surveys detect over five thousand new species in future mining hotspot
(via sciencedaily.com) Original source There is a massive, mineral-rich region in the Pacific Ocean -- about twice the size of India -- called the Clarion-Clipperton Zone (CCZ), which has already been divided up and assigned to companies for future deep-sea mining. To better understand what may be at risk once companies start mining, a team of biologists has built the first 'CCZ checklist' by compiling all the species records from previous research expeditions to the region. Their estimates of the species diversity of the CCZ included a total of 5,578 different species, an estimated 88% - 92% of which are entirely new to science.
Published Deadly virus structures point toward new avenues for vaccine design
(via sciencedaily.com) Original source By comparing the structures of protein complexes from different lineages of the dangerous Lassa virus, a team identified new antibodies and vaccine targets.
Published Most effective ways of foraging can attract predators
(via sciencedaily.com) Original source Animals using the most of efficient methods of searching for resources may well pay with their lives, scientists have discovered.
Published How tasty is the food?
(via sciencedaily.com) Original source A hormone and specialized brain cells regulate feeding behavior in mice.
Published Failed antibiotic now a game changing weed killer for farmers
(via sciencedaily.com) Original source Weed killers of the future could soon be based on failed antibiotics. Researchers have found a molecule which was initially developed to treat tuberculosis but failed to progress out of the lab as an antibiotic is now showing promise as a powerful foe for weeds that invade our gardens and cost farmers billions of dollars each year.
Published Global macrogenetic map of marine habitat-forming species
(via sciencedaily.com) Original source Species known as marine habitat-forming species -- gorgonians, corals, algae, seaweeds, marine phanerogams, etc.-- are organisms that help generate and structure the underwater landscapes. These are natural refuges for other species, and provide biomass and complexity to the seabeds. But these key species in marine ecosystems are currently threatened by climate change and other perturbations derived from human activity. Now, a study warns that even in the marine protected areas (MPAs) the genetic diversity of structural species is not protected, although it is essential for the response and adaptation of populations to changes that alter the natural environment.
Published Study shows key role for human T cells in the control of Respiratory Syncytial Virus (RSV) infection
(via sciencedaily.com) Original source A new study has shown that human T cells have an important role to play in controlling infection.
Published Quantum matter breakthrough: Tuning density waves
(via sciencedaily.com) Original source Scientists have found a new way to create a crystalline structure called a 'density wave' in an atomic gas. The findings can help us better understand the behavior of quantum matter, one of the most complex problems in physics.
Published Where do our limbs come from?
(via sciencedaily.com) Original source Scientists have uncovered new clues about the origin of paired appendages -- a major evolutionary step that remains unresolved and highly debated.
Published Move over, armadillos: There's a new bone-plated mammal in town
(via sciencedaily.com) Original source Armadillos have long been considered to be the only living mammals that produce protective bony plates. But a new study unexpectedly shows that African spiny mice produce the same structures beneath the skin of their tails, which until now had gone largely undetected.
Published A look into the heart of cellular waste disposal
(via sciencedaily.com) Original source Researchers reveal how a nanomachine takes care of cleaning up inside the cell.
Published Scientists from the Global South innovate to track ongoing amphibian pandemic
(via sciencedaily.com) Original source Scientists have developed and validated an assay that could be used to diagnose Indian strains of the amphibian chytrid fungus that were not detected by previous tests. The novel assay also works for other better-known strains from other parts of the world, such as the one present in Panama.
Published Engineers create bacteria that can synthesize an unnatural amino acid
(via sciencedaily.com) Original source Researchers have engineered bacteria to synthesize an amino acid that contains a rare functional group that others have shown to have implications in the regulation of our immune system. The researchers also taught a single bacterial strain to create the amino acid and place it at specific sites within target proteins. These findings provide a foundation for developing unique vaccines and immunotherapies in the future.
Published Flexing crystalline structures provide path to a solid energy future
(via sciencedaily.com) Original source Researchers have uncovered the atomic mechanisms that make a class of compounds called argyrodites attractive candidates for both solid-state battery electrolytes and thermoelectric energy converters. The discoveries -- and the machine learning approach used to make them -- could help usher in a new era of energy storage for applications such as household battery walls and fast-charging electric vehicles.
Published What marsupials can teach us about brain development
(via sciencedaily.com) Original source Research has revealed features of early human brain development are mimicked in the brains of marsupials.
Published Previous smallpox vaccine provides immunity to mpox
(via sciencedaily.com) Original source Vaccines against smallpox given until the mid-1970s offer continuing cross-reactive immunity to mpox (previously known as monkeypox), researchers report.
