Published Should you eat more dietary fiber? New study says it depends
(via sciencedaily.com) Original source Nutritionists generally advise everyone to eat more dietary fiber, but a new study suggests that its effects on health can vary from person to person. The findings indicate that recommendations should be tailored to each individual's gut microbiome.
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 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 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 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 Is coffee good for you or bad for you?
(via sciencedaily.com) Original source The effects of coffee consumption on human health is a knotty question, but one thing is sure: coffee is a psychoactive substance.
Published How targeted nutrients can fight cancer
(via sciencedaily.com) Original source An international research team has discovered a new way to effectively treat cancer, by using nutrients to reactivate suppressed metabolic pathways in cancer cells.
Published The world's oldest wine discovered
(via sciencedaily.com) Original source A white wine over 2,000 years old, of Andalusian origin, is the oldest wine ever discovered.
Published Where to put head and tail?
(via sciencedaily.com) Original source Formation of the body axes is a critical part of embryonic development. They guarantee that all body parts end up where they belong and that no ears grow on our backs. The head-tail axis, for example, determines the orientation of the two ends of the body. It was previously assumed that this axis is largely determined by the interplay between the Nodal and BMP signals. However, there appears to be another player in this system, as researchers have now discovered by using an embryo-like model system they developed. In the absence of BMP, the signalling molecule beta-catenin takes on the role of the Nodal antagonist. This new mechanism could be a flexible solution for axis formation in embryos with different shapes.
Published How the ketogenic diet improves healthspan and memory in aging mice
(via sciencedaily.com) Original source The ketogenic diet has its fanatics and detractors among dieters, but either way, the diet has a scientifically documented impact on memory in mice. While uncovering how the high fat, low carbohydrate diet boosts memory in older mice, scientists identified a new molecular signaling pathway that improves synapse function and helps explain the diet's benefit on brain health and aging.
Published A high-fat diet may fuel anxiety
(via sciencedaily.com) Original source New research shows when animals are fed a diet high in saturated fat for nine weeks, their gut bacteria change in ways that influence brain chemicals and fuel anxiety.
Published Wear it, then recycle: Designers make dissolvable textiles from gelatin
(via sciencedaily.com) Original source Researchers hope their DIY machine will help designers around the world experiment with making their own, sustainable fashion and other textiles from a range of natural ingredients -- maybe even the chitin in crab shells or agar-agar from algae.
Published Previously uncharacterized parasite uncovered in fish worldwide
(via sciencedaily.com) Original source Using genome reconstruction, scientists unveiled a once 'invisible' fish parasite present in many marine fish world-wide that belongs to the apicomplexans, one of the most important groups of parasites at a clinical level. However, it had gone unnoticed in previous studies. The parasite is geographically and taxonomically widespread in fish species around the planet, with implications for commercial fishing and oceanic food webs.
Published Research into structures of ape hearts provide insight into human evolution
(via sciencedaily.com) Original source Researchers have discovered new insights into the human heart's structure, revealing its evolutionary history. This study enhances understanding of heart development and its implications for treating heart disease.
Published When bacteria are buckling
(via sciencedaily.com) Original source Filamentous cyanobacteria buckle at a certain length when they encounter an obstacle. The results provide an important basis for the use of cyanobacteria in modern biotechnology.
Published Vitamin B6: New compound delays degradation
(via sciencedaily.com) Original source A low vitamin B6 level has negative effects on brain performance. A research team has now found a way to delay the degradation of the vitamin.
