Published 3D-printed chip sensor detects foodborne pathogens for safer products
(via sciencedaily.com) Original source Researchers have developed a new method for detecting foodborne pathogens that is faster, cheaper, and more effective than existing methods. Their microfluidic chip uses light to detect multiple types of pathogens simultaneously and is created using 3D printing, making it easy to fabricate in large amounts and modify to target specific pathogens. The researchers hope their technique can improve screening processes and keep contaminated food out of the hands of consumers.
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 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 A hidden treasure in the Milky Way -- Astronomers uncover ultrabright x-ray source
(via sciencedaily.com) Original source Astronomers uncovered that a well-known X-ray binary, whose exact nature has been a mystery to scientists until now, is actually a hidden ultraluminous X-ray source.
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 Resiliency shaped by activity in the gut microbiome and brain
(via sciencedaily.com) Original source A new study has found that resilient people exhibit neural activity in the brain regions associated with improved cognition and regulating of emotions, and were more mindful and better at describing their feelings.
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.
Published Wild chimpanzees seek out medicinal plants to treat illness and injuries
(via sciencedaily.com) Original source Chimpanzees appear to consume plants with medicinal properties to treat their ailments, according to a new study.
Published Supermassive black hole appears to grow like a baby star
(via sciencedaily.com) Original source Supermassive black holes pose unanswered questions for astronomers around the world, not least 'How do they grow so big?' Now, an international team of astronomers has discovered a powerful rotating, magnetic wind that they believe is helping a galaxy's central supermassive black hole to grow. The swirling wind, revealed with the help of the ALMA telescope in nearby galaxy ESO320-G030, suggests that similar processes are involved both in black hole growth and the birth of stars.
Published Newly discovered dinosaur boasts big, blade-like horns
(via sciencedaily.com) Original source A new dinosaur has been identified and named. The dinosaur's name, Lokiceratops rangiformis, translates roughly to 'Loki's horned face that looks like a caribou.'
Published First conclusive evidence that a terrestrial leech species can jump
(via sciencedaily.com) Original source A new study presents video evidence that at least one species of terrestrial leech can jump, behavior that scientists have debated for more than a century.
Published Wild yeasts from Patagonia could yield new flavors of lagers
(via sciencedaily.com) Original source New strains of yeast for brewing lager beers, created by hybridizing wild strains of yeast from Patagonia with brewer's yeast, can yield novel flavors and aromas, researchers report.
Published Hurricane changed 'rules of the game' in monkey society
(via sciencedaily.com) Original source A devastating hurricane transformed a monkey society by changing the pros and cons of interacting with others, new research shows.
Published Blessing in disguise: Mycoviruses enhance fungicide effectiveness against plant pathogens
(via sciencedaily.com) Original source Researchers discovered that mycoviruses, or oomycete viruses, can increase the sensitivity of plant pathogenic oomycete to fungicides like metalaxyl. Their findings suggest greater potential for mycoviruses in biocontrol and contributing to sustainable agriculture.
Published Interaction with insects accelerates plant evolution
(via sciencedaily.com) Original source Researchers have discovered that plants benefit from a greater variety of interactions with pollinators and herbivores. Plants that are pollinated by insects and have to defend themselves against herbivores have evolved to be better adapted to different types of soil.
