Published Warming stops tiny organisms working together
(via sciencedaily.com) Original source Hotter conditions prevent two tiny organisms working together for mutual benefit, new research shows.
Published Mass extinction 66 million years ago triggered rapid evolution of bird genomes
(via sciencedaily.com) Original source Study finds that the mass extinction caused by an asteroid about 66 million years ago led to critical changes in bird genomes that ultimately sparked the incredibly diversity living birds.
Published Scientists devise method to secure Earth's biodiversity on the moon
(via sciencedaily.com) Original source New research led proposes a plan to safeguard Earth's imperiled biodiversity by cryogenically preserving biological material on the moon. The moon's permanently shadowed craters are cold enough for cryogenic preservation without the need for electricity or liquid nitrogen.
Published Researchers explore cancer susceptibility in birds
(via sciencedaily.com) Original source In one of the largest studies of cancer susceptibility across bird species, researchers describe an intriguing relationship between reproductive rates and cancer susceptibility.
Published Cash and conservation: A worldwide analysis of wildlife represented on money
(via sciencedaily.com) Original source Researchers investigate the representation of native fauna on 4,541 banknotes from 207 countries between 1980 and 2017, to identify geographic hotspots and taxonomic patterns, and determine whether threatened and endemic species were more readily represented.
Published Monarch butterflies need help, and a little bit of milkweed goes a long way
(via sciencedaily.com) Original source Researchers and community scientists monitored urban milkweed plants for butterfly eggs to learn what makes these city gardens more hospitable to monarchs. They found that even tiny city gardens attracted monarchs and became a home to caterpillars.
Published More electricity from the sun
(via sciencedaily.com) Original source A coating of solar cells with special organic molecules could pave the way for a new generation of solar panels. This coating can increase the efficiency of monolithic tandem cells made of silicon and perovskite while lowering their cost -- because they are produced from industrial, microstructured, standard silicon wafers.
Published Physicists use light to probe deeper into the 'invisible' energy states of molecules
(via sciencedaily.com) Original source Physicists have experimentally demonstrates a novel physical effect that was predicted 45 years ago. The effect will result in a new chemical analysis technique, to simultaneously identify molecular bonds and their 3D arrangement in space. This new technique will find applications in pharmaceutical science, security, forensics, environmental science, art conservation, and medicine.
Published Green hydrogen: 'Artificial leaf' becomes better under pressure
(via sciencedaily.com) Original source Hydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so called photoelectrochemical cells (PEC cells). A research team has now shown that the efficiency of PEC cells can be significantly increased under pressure.
Published Scientists discover entirely new wood type that could be highly efficient at carbon storage
(via sciencedaily.com) Original source Researchers undertaking an evolutionary survey of the microscopic structure of wood from some of the world's most iconic trees and shrubs have discovered an entirely new type of wood.
Published Super-black wood can improve telescopes, optical devices and consumer goods
(via sciencedaily.com) Original source Thanks to an accidental discovery, researchers have created a new super-black material that absorbs almost all light, opening potential applications in fine jewelry, solar cells and precision optical devices.
Published Researchers identify unique phenomenon in Kagome metal
(via sciencedaily.com) Original source A new study focuses on how a particular Kagome metal interacts with light to generate what are known as plasmon polaritons -- nanoscale-level linked waves of electrons and electromagnetic fields in a material, typically caused by light or other electromagnetic waves.
Published What no one has seen before -- simulation of gravitational waves from failing warp drive
(via sciencedaily.com) Original source Physicists have been exploring the theoretical possibility of spaceships driven by compressing the four-dimensional spacetime for decades. Although this so-called 'warp drive' originates from the realm of science fiction, it is based on concrete descriptions in general relativity. A new study takes things a step further -- simulating the gravitational waves such a drive might emit if it broke down.
Published Scientists using new sound tech to save animals from extinction
(via sciencedaily.com) Original source Scientists are using new technology to help endangered animals by listening to their sounds.
Published North Sea oil and gas extraction spikes pollution by 10,000 percent, study finds
(via sciencedaily.com) Original source North Sea oil and gas extraction can cause pollution to spike by more than 10,000 percent within half a kilometer around off-shore sites, a study has found. The research has uncovered the true impact on Britain's seabed life -- with the number of species plummeting nearly 30 percent near platforms.
Published Researchers trap atoms, forcing them to serve as photonic transistors
(via sciencedaily.com) Original source Researchers have developed a means to realize cold-atom integrated nanophotonic circuits.
Published Scientists untangle interactions between the Earth's early life forms and the environment over 500 million years
(via sciencedaily.com) Original source The atmosphere, the ocean and life on Earth interacted over the past 500-plus million years in ways that improved conditions for early organisms to thrive. Now, an interdisciplinary team of scientists has produced a perspective article of this co-evolutionary history.
Published Optical fibers fit for the age of quantum computing
(via sciencedaily.com) Original source A new generation of specialty optical fibers has been developed by physicists to cope with the challenges of data transfer expected to arise in the future age of quantum computing.
Published Climate is most important factor in where mammals choose to live, study finds
(via sciencedaily.com) Original source Using data from 6,645 camera traps across the United States, researchers mapped populations of 25 mammal species. They determined that climate, not human activity, was the primary factor in mammals deciding where to live.
Published Atomic 'GPS' elucidates movement during ultrafast material transitions
(via sciencedaily.com) Original source Scientists have created the first-ever atomic movies showing how atoms rearrange locally within a quantum material as it transitions from an insulator to a metal. With the help of these movies, the researchers discovered a new material phase that settles a years-long scientific debate and could facilitate the design of new transitioning materials with commercial applications.
