Published Microrobot technology: Externally connecting in vivo neural networks
(via sciencedaily.com) Researchers have developed a technology for delivering a microrobot to a target point of a hippocampus in an in-vitro environment, connecting neural networks, and measuring neural signals. The findings are expected to contribute to neural network research and the verification and analysis of cell therapy products.
Published Researchers discover birds with neurotoxin-laden feathers
(via sciencedaily.com) An expedition into the jungle of New Guinea has resulted in the discovery of two new species of poisonous birds. Genetic changes in these bird species have allowed them to carry a powerful neurotoxin.
Published Scallop eyes as inspiration for new microscope objectives
(via sciencedaily.com) Original source Neuroscientists have developed innovative objectives for light microscopy by using mirrors to produce images. Their design finds correspondence in mirror telescopes used in astronomy on the one hand and the eyes of scallops on the other. The new objectives enable high-resolution imaging of tissues and organs in a much wider variety of immersion media than with conventional microscope lenses.
Published Scientists observe flattest explosion ever seen in space
(via sciencedaily.com) Original source Astronomers have observed an explosion 180 million light years away which challenges our current understanding of explosions in space, that appeared much flatter than ever thought possible.
Published Form is (mal)function: Protein's shape lets bacteria disarm it
(via sciencedaily.com) Shigella bacteria can infect humans but not mice. A team can now explain why. Their findings may explain the multifariousness of a key weapon of our immune system.
Published New, exhaustive study probes hidden history of horses in the American West
(via sciencedaily.com) Indigenous peoples as far north as Wyoming and Idaho may have begun to care for horses by the first half of the 17th Century, according to a new study by researchers from 15 countries and multiple Native American groups.
Published Boosting the body's anti-viral immune response may eliminate aging cells
(via sciencedaily.com) Original source Aging cells express a protein that is produced by human cytomegalovirus and is targeted by certain immune cells in the body. Harnessing the immune response to this protein could have multiple health benefits during aging.
Published White-tailed deer blood kills bacteria that causes Lyme disease
(via sciencedaily.com) Original source As tick season kicks in across the country, scientists have completed research that offers a promising lead in the fight against Lyme disease.
Published How plants cope with the cold light of day -- and why it matters for future crops
(via sciencedaily.com) New research has discovered a cold 'coping' mechanism that is under the control of the plant biological clock and could offer solutions to breeding more resilience into crops less suited to cold climates.
Published New details of SARS-COV-2 structure
(via sciencedaily.com) Researchers used computational modeling to reveal finer details surrounding the outer shell of the COVID-19 virus. The work expands the scientific community's understanding of SARS-COV-2, and could lead to more refined antiviral therapies and better vaccines.
Published T cells in human blood secrete a substance that affects blood pressure and inflammation
(via sciencedaily.com) Original source Acetylcholine regulates blood flow, but the source of blood acetylcholine has been unclear. Now, researchers have discovered that certain T cells in human blood can produce acetylcholine, which may help regulate blood pressure and inflammation. The study also demonstrates a possible association between these immune cells in seriously ill patients and the risk of death.
Published Scientists see anti-aging potential in an invasive weed
(via sciencedaily.com) Original source The fruit of the cocklebur plant, which grows worldwide and is often considered a noxious weed, has antioxidant and anti-inflammatory components that could make it useful as a skin protectant, according to new research.
Published 'Taffy galaxies' collide, leave behind bridge of star-forming material
(via sciencedaily.com) Original source The Gemini North telescope, one half of the International Gemini Observatory, operated by NSF's NOIRLab, captured a dazzling image of UGC 12914 and UGC 12915, which are nicknamed the Taffy Galaxies. Their twisted shape is the result of a head-on collision that occurred about 25 million years prior to their appearance in the image. A bridge of highly turbulent gas devoid of significant star formation spans the gap between the two galaxies.
Published Scientists discover hidden crab diversity among coral reefs
(via sciencedaily.com) The Indo-West Pacific is the largest marine ecosystem on Earth, but scientists who study its diversity have to contend with a problem so well-known it was remarked upon by Charles Darwin: related species in the IWP have similar appearances, making it difficult to assess just how many there are. A new study reveals that nearly identical crab species have one consistently distinguishing feature, which only evolves when their ranges overlap.
Published Astronomers witness the birth of a very distant cluster of galaxies from the early Universe
(via sciencedaily.com) Original source Astronomers have discovered a large reservoir of hot gas in the still-forming galaxy cluster around the Spiderweb galaxy -- the most distant detection of such hot gas yet. Galaxy clusters are some of the largest objects known in the Universe and this result further reveals just how early these structures begin to form.
Published How the gut creates a cozy home for beneficial microbiome species
(via sciencedaily.com) Original source The digestive tract of fruit flies remodels itself to accommodate beneficial microbiome species and maintain long-term stability of the gut environment, according to new research.
Published How cosmic winds transform galactic environments
(via sciencedaily.com) Original source Much like how wind plays a key role in life on Earth by sweeping seeds, pollen and more from one place to another, galactic winds -- high-powered streams of charged particles and gases -- can change the chemical make-up of the host galaxies they form in, simply by blowing in a specific direction.
Published Rainbow trout subspecies newly named
(via sciencedaily.com) Original source The McCloud River redband trout, or O. mykiss calisulat, is newly identified as its own distinct subspecies of rainbow trout in a new study. It was named in consultation with the Winnemem Wintu tribe.
Published Earth prefers to serve life in XXS and XXL sizes
(via sciencedaily.com) Life comes in all shapes in sizes, but some sizes are more popular than others, new research has found. A survey of body sizes of all Earth's living organisms has uncovered an unexpected pattern. Contrary to what current theories can explain, our planet's biomass -- the material that makes up all living organisms -- is concentrated in organisms at either end of the size spectrum.
Published Moths are more efficient pollinators than bees, shows new research
(via sciencedaily.com) Moths are more efficient pollinators at night than day-flying pollinators such as bees, finds new research.
