Published Scientists harness quantum microprocessor chips for revolutionary molecular spectroscopy simulation
(via sciencedaily.com) Original source Engineering researchers have successfully developed a quantum microprocessor chip for molecular spectroscopy simulation of actual large-structured and complex molecules.
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 Gut microbial pathway identified as target for improved heart disease treatment
(via sciencedaily.com) Original source Researchers have made a significant discovery about how the gut microbiome interacts with cells to cause cardiovascular disease. The study found phenylacetylglutamine (PAG), produced by gut bacteria as a waste product, then absorbed and formed in the liver, interacts with previously undiscovered locations on beta-2 adrenergic receptors on heart cells once it enters the circulation.
Published Researchers develop an instant version of trendy, golden turmeric milk
(via sciencedaily.com) Original source If you've visited a trendy cafe in the past few years, you might have noticed 'golden' turmeric milk on the menu. This fancy drink is caffeine-free, coffee-free and can even be vegan. And now, researchers have developed an efficient method to make a powdered, plant-based, instant version that maintains the beneficial properties of the ingredients while also extending its shelf life.
Published Key biofuel-producing microalga believed to be a single species is actually three
(via sciencedaily.com) Original source When a global pandemic forced previous a graduate student out of the lab and onto the computer, he found a world of difference hidden in the long-studied species of Botryoccocus braunii -- and discovered that it isn't one species at all, but three.
Published New insights on how bird flu crosses the species barrier
(via sciencedaily.com) Original source The avian influenza virus needs to mutate to cross the species barrier and to infect and replicate within mammalian cells. Scientists have now deciphered the structure of the avian influenza virus's polymerase when it interacts with a human protein essential for the virus to replicate within the cell. The structure of this replication complex provides important information about the mutations that avian influenza polymerase must undergo to adapt to mammals, including humans. These results can help scientists monitor the evolution and adaptability of bird flu strains, such as H5N1 or H7N9, towards infecting other species.
Published Searching old stem cells that stay young forever
(via sciencedaily.com) Original source The sea anemone Nematostella vectensis is potentially immortal. Using molecular genetic methods, developmental biologists have now identified possible candidates for multipotent stem cells in the sea anemone for the first time. These stem cells are regulated by evolutionary highly conserved genes.
Published Low cortisol, hair-trigger stress response in the brain may underlie Long COVID
(via sciencedaily.com) Original source A new animal study shows that exposure to immune-stimulating proteins left behind by COVID-19 leads to lower cortisol, brain inflammation and a heightened reaction to subsequent stressors.
Published Weight-loss success depends on eating more protein, fiber while limiting calories
(via sciencedaily.com) Original source Flexibility and personalization were key in optimizing dieters' weight-loss success on the Individualized Diet Improvement Program, created by food scientists.
Published Preliminary study shows potential of Manuka honey as a nutraceutical for breast cancer
(via sciencedaily.com) Original source A new study found that Manuka honey could potentially be an alternative, natural option for breast cancer prevention and treatment -- particularly for estrogen receptor (ER)-positive breast cancer, the most common subtype of breast cancer that accounts for about 70-80% of all breast cancer cases.
Published Mining the microbiome: Uncovering new antibiotics inside the human gut
(via sciencedaily.com) Original source Researchers surveyed the gut microbiomes of nearly 2,000 people, discovering dozens of potential new antibiotics. The lead candidate, prevotellin-2, demonstrated anti-infective capabilities on par with polymyxin B, an FDA-approved antibiotic used today to treat multidrug-resistant infections, suggesting that the human gut microbiome may contain antibiotics that will someday find clinical application.
Published Ancient DNA reveals Indigenous dog lineages found at Jamestown, Virginia
(via sciencedaily.com) Original source Previous scientific studies have indicated that North American dog lineages were replaced with European ones between 1492 and the present day. To better understand the timing of this replacement, researchers sequenced mitochondrial DNA from archaeological dogs. Their findings suggest a complex social history of dogs during the early colonial period.
Published Knocking out one key gene leads to autistic traits
(via sciencedaily.com) Original source Hyperactivity, repetitive behavior, and language deficits all appeared in the mice, highlighting an unexpected role the cerebellum seems to play in autism.
Published Large Hadron Collider pipe brings search for elusive magnetic monopole closer than ever
(via sciencedaily.com) Original source New research using a decommissioned section of the beam pipe from the Large Hadron Collider (LHC) at CERN has bought scientists closer than ever before to test whether magnetic monopoles exist. Scientists have revealed the most stringent constraints yet on the existence of magnetic monopoles, pushing the boundaries of what is known about these elusive particles.
Published Researchers observe 'locked' electron pairs in a superconductor cuprate
(via sciencedaily.com) Original source The finding could help future efforts to design superconductors that work at higher temperatures.
Published Probiotics during pregnancy shown to help moms and babies
(via sciencedaily.com) Original source Giving probiotics to pregnant mice can enhance both the immune system and behavior of the mothers and their offspring.
Published New insight Into behavior of electrons
(via sciencedaily.com) Original source Physicists have uncovered new states of matter by exploring the behavior of flatland electrons in extreme conditions, revealing insights that could impact quantum computing and advanced materials.
Published Nearly 25% of European landscape could be rewilded, researchers say
(via sciencedaily.com) Original source Europe's abandoned farmlands could find new life through rewilding, a movement to restore ravaged landscapes to their wilderness before human intervention. A quarter of the European continent, 117 million hectares, is primed with rewilding opportunities, researchers report.
Published Quantum pumping in molecular junctions
(via sciencedaily.com) Original source Researchers have developed a new theoretical modelling technique that could potentially be used in the development of switches or amplifiers in molecular electronics.
Published Zebrafish use surprising strategy to regrow spinal cord
(via sciencedaily.com) Original source A new study maps out a detailed atlas of all the cells involved in regenerating the zebrafish spinal cord. In an unexpected finding, the researchers showed that survival and adaptability of the severed neurons themselves is required for full spinal cord regeneration. Surprisingly, the study showed that stem cells capable of forming new neurons play a complementary role but don t lead the process.
