Published Pilot study uses recycled glass to grow plants for salsa ingredients
(via sciencedaily.com) Original source Tortilla chips and fresh salsa are tasty, but they could be even more appealing if you grow the ingredients yourself. Now, researchers report that some salsa ingredients -- cilantro, bell pepper and jalapeno -- can be more sustainably cultivated with recycled glass. Their pilot study found that partially substituting soil in a planter with recycled glass fragments speeds up plant development and reduces unwanted fungal growth.
Published Survival tactics: AI-driven insights into chromatin changes for winter dormancy in axillary buds
(via sciencedaily.com) Original source Epigenetics confers a survival advantage in plants to endure harsh weather by inducing bud dormancy. Environmental factors or intrinsic signals trigger the transition between growth and dormancy. Researchers explore the role of chromatin and transcriptional changes in the bud and further analyze data using artificial intelligence models. The findings of this study highlight epigenetic strategies to overcome the effects of short winters during global warming for plant survival.
Published Beetle that pushes dung with the help of 100 billion stars unlocks the key to better navigation systems in drones and satellites
(via sciencedaily.com) Original source An insect species that evolved 130 million years ago is the inspiration for a new research study to improve navigation systems in drones, robots, and orbiting satellites.
Published The power of face time: Insights from zebra finch courtship
(via sciencedaily.com) Original source A new study on songbirds sheds light on the power of social interaction to facilitate learning, insights that potentially apply to human development. Researchers discovered that zebra finches deprived of early social experiences could still form strong bonds with a partner later in life. Once placed into cohabitation with a male, females that had never heard a mating song before could quickly develop a preference for his melody.
Published 'DNA scavengers' can stop some antibiotic resistance from spreading
(via sciencedaily.com) Original source For nearly a century, scientists have waged war on antibiotic-resistant microbes. Researchers say they've found a new way to prevent it -- by unleashing 'DNA scavengers' in wastewater treatment plants.
Published Benefits and downside of fasting
(via sciencedaily.com) Original source Researchers identified a signaling pathway in mice that boosts intestinal stem cells' regeneration abilities after fasting. When cancerous mutations occurred during this regenerative period, mice were more likely to develop early-stage intestinal tumors.
Published New heaviest exotic antimatter nucleus
(via sciencedaily.com) Original source Scientists studying the tracks of particles streaming from six billion collisions of atomic nuclei at the Relativistic Heavy Ion Collider (RHIC) -- an 'atom smasher' that recreates the conditions of the early universe -- have discovered a new kind of antimatter nucleus, the heaviest ever detected. Composed of four antimatter particles -- an antiproton, two antineutrons, and one antihyperon -- these exotic antinuclei are known as antihyperhydrogen-4.
Published Self-repairing mitochondria use novel recycling system
(via sciencedaily.com) Original source A newly identified identified cellular mechanism allows mitochondria to recycle localized damage and maintain healthy function.
Published Surprising mechanism for removing dead cells identified
(via sciencedaily.com) Original source A tandem signaling process turns ordinary cells into an efficient cleanup crew.
Published Compound in rosemary extract can reduce cocaine sensitivity
(via sciencedaily.com) Original source A team of researchers has discovered that an antioxidant found in rosemary extract can reduce volitional intakes of cocaine by moderating the brain's reward response, offering a new therapeutic target for treating addiction.
Published Humpbacks are among animals who manufacture and wield tools
(via sciencedaily.com) Original source Researchers suggest a new designation of the humpback whales they study: tool wielders. Researchers have known that humpback whales create "bubble-nets" to hunt, but they have learned that the animals don't just create the bubble-nets; they manipulate this unique tool in a variety of ways to maximize their food intake in Alaskan feeding grounds.
Published New view of North Star reveals spotted surface
(via sciencedaily.com) Original source High-resolution images show large spots on the surface of Polaris.
Published 'Masters of shape-shifting': How darkling beetles conquered the world
(via sciencedaily.com) Original source Large-scale genomic analysis of darkling beetles, a hyper-diverse insect group of more than 30,000 species worldwide, rolls back the curtain on a 150-million-year evolutionary tale of one of Earth's most ecologically important yet inconspicuous creatures, according to new research.
Published New worm study paves way for better RNA-based drugs to treat human disease
(via sciencedaily.com) Original source Researchers have discovered RNA mechanisms that may lead to more effective, durable and targeted treatments for conditions like high cholesterol, liver diseases and cancers.
Published Deadly sea snail toxin could be key to making better medicines
(via sciencedaily.com) Original source Scientists are finding clues for how to treat diabetes and hormone disorders in an unexpected place: a toxin from one of the most venomous animals on the planet.
Published Adaptive 3D printing system to pick and place bugs and other organisms
(via sciencedaily.com) Original source A new adaptive 3D printing system can identify the positions of randomly distributed organisms and safely move them to specific locations for assembly.
Published Scientists discover new code governing gene activity
(via sciencedaily.com) Original source A newly discovered code within DNA -- coined 'spatial grammar' -- holds a key to understanding how gene activity is encoded in the human genome. This breakthrough finding revealed a long-postulated hidden spatial grammar embedded in DNA. The research could reshape scientists' understanding of gene regulation and how genetic variations may influence gene expression in development or disease.
Published Researchers uncover the secrets of 'plant puberty'
(via sciencedaily.com) Original source Researchers have identified the genetic changes linked to why plants go through a developmental change similar to 'puberty' at different rates, a discovery which could lead to better crop nutrition.
Published Analyzing 'Finnegans Wake' for novel spacing between punctuation marks
(via sciencedaily.com) Original source James Joyce's tome 'Finnegans Wake' famously breaks the rules of normal prose through its unusual, dreamlike stream of consciousness, and new work in chaos theory takes a closer look at how Joyce's challenging novel stands out mathematically. Researchers compared the distribution of punctuation marks in various experimental novels to determine the underlying order of 'Finnegans Wake' and by statistically analyzing the texts, researchers found the tome exhibits an unusual but statistically identifiable structure. The wide singularity spectrum was perfectly symmetrical, meaning sentence length variability follows an orderly curve.
Published Spectacular increase in the deuterium/hydrogen ratio in Venus' atmosphere
(via sciencedaily.com) Original source Our understanding of Venus' water history and the potential that it was once habitable in the past is being challenged by recent observations.
