Published Light-weight microscope captures large-scale brain activity of mice on the move
(via sciencedaily.com) Original source With a new microscope that's as light as a penny, researchers can now observe broad swaths of the brain in action as mice move about and interact with their environments.
Published Rewriting the armadillo family tree: A new species, plus a name change for the state mammal of Texas
(via sciencedaily.com) Original source The nine-banded armadillo, which ranges all the way from Argentina to Nebraska, is actually four separate species. One of the species, the Guianan long-nosed armadillo, is new to science. Meanwhile, the species that has migrated from Mexico to the United States (and is the official small mammal of Texas) is now called the Mexican long-nosed armadillo.
Published Frog 'saunas' a lifeline for endangered frog populations
(via sciencedaily.com) Original source New biologist-designed shelters will help endangered frogs survive the devastating impacts of a deadly fungal disease by regulating their body temperature to fight off infections.
Published Zebrafish reveal how bioelectricity shapes muscle development
(via sciencedaily.com) Original source New research describes how nerve cells and muscle cells communicate through electrical signals during development -- a phenomenon known as bioelectricity. The communication, which takes place via specialized channels between cells, is vital for proper development and behavior. The study identifies specific genes that control the process, and pins down what happens when it goes wrong. The finding offers clues to the genetic origins of muscle disorders in humans.
Published Non-stop flight: 4,200 km transatlantic flight of the Painted Lady butterfly mapped
(via sciencedaily.com) Original source In October 2013 a researcher made a surprising discovery of Painted Lady Butterflies on the Atlantic beaches of French Guiana -- a species not typically found in South America. This unusual sighting prompted an international study to investigate the origin of these butterflies.
Published New evidence for how heat is transported below the sun's surface
(via sciencedaily.com) Original source Solar physicists have revealed the interior structure of the sun's supergranules, a flow structure that transports heat from the sun's hidden interior to its surface. The researchers' analysis of the supergranules presents a challenge to the current understanding of solar convection.
Published Telltale greenhouse gases could signal alien activity
(via sciencedaily.com) Original source If aliens modified a planet in their solar system to make it warmer, we'd be able to tell. A new study identifies the artificial greenhouse gases that would be giveaways of a terraformed planet.
Published Marsquakes may help reveal whether liquid water exists underground on red planet
(via sciencedaily.com) Original source If liquid water exists today on Mars, it may be too deep underground to detect with traditional methods used on Earth. But listening to earthquakes that occur on Mars -- or marsquakes -- could offer a new tool in the search.
Published First of its kind detection made in striking new Webb image
(via sciencedaily.com) Original source For the first time, a phenomenon astronomers have long hoped to directly image has been captured by NASA's James Webb Space Telescope's Near-Infrared Camera (NIRCam). In this stunning image of the Serpens Nebula, the discovery lies in the northern area of this young, nearby star-forming region.
Published Geologists expect Chang'e-6 lunar surface samples to contain volcanic rock and impact ejecta
(via sciencedaily.com) Original source On June 25, China's Chang'e-6 (CE-6) lunar probe is set to return to Earth, carrying the first surface samples collected from the farside of the Moon. In anticipation of this historic event, scientists are publishing their predictions for the unique materials that may be found in the CE-6 samples.
Published Myths about intermittent fasting, debunked
(via sciencedaily.com) Original source Research shows that the increasingly popular weight-loss strategy is safe. Intermittent fasting has become an increasingly popular way to lose weight without counting calories. And a large body of research has shown it s safe. Still, several myths about fasting have gained traction.
Published Mashed up purple marine bacteria makes an excellent eco-friendly fertilizer
(via sciencedaily.com) Original source New research reports that biomass made from the purple photosynthetic marine bacterium Rhodovulum sulfidophilum is an excellent nitrogen fertilizer. The biomass fertilizer proved to be just as effective as common inorganic synthetic fertilizers but avoids several side effects that harm the environment, making it an eco-friendly alternative.
Published Removal of excess chloride ions by plants when subjected to salt stress
(via sciencedaily.com) Original source Researchers have discovered a salt adaptation mechanism in plants that facilitates chloride removal from the roots and enhancing salinity tolerance. A research team has uncovered a novel mechanism of plant adaptation to salt stress involving the NaCl-induced translocation of a specific chloride channel protein, AtCLCf.
Published How cells boost gene expression
(via sciencedaily.com) Original source The function of non-coding RNA in the cell has long been a mystery to researchers. Unlike coding RNA, non-coding RNA does not produce proteins -- yet it exists in large quantities. A research team has now discovered an important function of antisense RNA (asRNA): the researchers found that asRNA acts as a 'superhighway' in cell transport and thus accelerates gene expression.
Published New tomato, potato family tree shows that fruit color and size evolved together
(via sciencedaily.com) Original source A new family tree of the plant genus Solanum helps explain the striking diversity of their fruit color and size. This genus includes tomatoes, potatoes, eggplants, and other economically important plants.
Published Star clusters observed within a galaxy in the early Universe
(via sciencedaily.com) Original source The history of how stars and galaxies came to be and evolved into the present day remains among the most challenging astrophysical questions to solve yet, but new research brings us closer to understanding it. New insights about young galaxies during the Epoch of Reionization have been revealed. Observations with the James Webb Space Telescope (JWST) of the galaxy Cosmic Gems arc (SPT0615-JD) have confirmed that the light of the galaxy was emitted 460 million years after the big bang. What makes this galaxy unique is that it is magnified through an effect called gravitational lensing, which has not been observed in other galaxies formed during that age.
Published Simple test for flu could improve diagnosis and surveillance
(via sciencedaily.com) Original source Fewer than one percent of people who get the flu every year get tested, in part because most tests require trained personnel and expensive equipment. Now researchers have developed a low-cost paper strip test that could allow more patients to find out which type of flu they have and get the right treatment. The test uses CRISPR to distinguish between the two main types of seasonal flu, influenza A and B, as well as seasonal flu subtypes H1N1 and H3N2. It can also identify strains that resist antiviral treatment, and with further work, could potentially detect swine and avian flu strains, including H5N1, which is currently infecting cattle.
Published Boosting biodiversity without hurting local economies
(via sciencedaily.com) Original source Protected areas, like nature reserves, can conserve biodiversity without harming local economic growth, countering a common belief that conservation restricts development. A new study outlines what is needed for conservation to benefit both nature and people.
Published Unifying behavioral analysis through animal foundation models
(via sciencedaily.com) Original source Behavioral analysis can provide a lot of information about the health status or motivations of a living being. A new technology makes it possible for a single deep learning model to detect animal motion across many species and environments. This 'foundational model', called SuperAnimal, can be used for animal conservation, biomedicine, and neuroscience research.
Published How to make aging a 'fairer game' for all wormkind
(via sciencedaily.com) Original source Researchers have discovered a new fundamental mechanism governing the rules of ageing in worms. The researchers were able to manipulate the mechanism through genetic interventions which dramatically extend not just the lifespan of the worms, but also their health-span. In other words, trading weak, frail old age with vigorous golden years -- all without altering their diet, environment or other external factors.
