Published The next generation of RNA chips
(via sciencedaily.com) Original source An international research team has succeeded in developing a new version of RNA building blocks with higher chemical reactivity and photosensitivity. This can significantly reduce the production time of RNA chips used in biotechnological and medical research. The chemical synthesis of these chips is now twice as fast and seven times more efficient.
Published Scientists devise method to secure Earth's biodiversity on the moon
(via sciencedaily.com) Original source New research led proposes a plan to safeguard Earth's imperiled biodiversity by cryogenically preserving biological material on the moon. The moon's permanently shadowed craters are cold enough for cryogenic preservation without the need for electricity or liquid nitrogen.
Published New principle for treating tuberculosis
(via sciencedaily.com) Original source Researchers have succeeded in identifying and synthesizing a group of molecules that can act against the cause of tuberculosis in a new way. They describe that the so-called callyaerins act against the infectious disease by employing a fundamentally different mechanism compared to antibiotic agents used to date.
Published Unraveling a key junction underlying muscle contraction
(via sciencedaily.com) Original source Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal kingdom and setting the stage for possible future treatments for muscular disorders.
Published Super-black wood can improve telescopes, optical devices and consumer goods
(via sciencedaily.com) Original source Thanks to an accidental discovery, researchers have created a new super-black material that absorbs almost all light, opening potential applications in fine jewelry, solar cells and precision optical devices.
Published Injury dressings in first-aid kits provide a new technique to reveal shark species after bite incidents
(via sciencedaily.com) Original source Scientists have revealed that injury dressings found in first-aid kits can reliably be used to identify shark species involved in bite incidents by deploying medical gauze to gather DNA samples from aquatic equipment, such as surfboards.
Published Precise genetics: New CRISPR method enables efficient DNA modification
(via sciencedaily.com) Original source A research group has developed a new method that further improves the existing CRISPR/Cas technologies: it allows a more precise and seamless introduction of tags into proteins at the gene level. This technology could significantly improve research on proteins in living organisms and opens up new possibilities for medical research.
Published Platypus and chicken reveal how chromosomes balance between the sexes
(via sciencedaily.com) Original source Geneticists uncover new insights into how sex chromosome systems work in the platypus and the chicken -- which will lead to better understandings of our own sex chromosome evolution and gene regulation.
Published How researchers turn bacteria into cellulose-producing mini-factories
(via sciencedaily.com) Original source Researchers have modified certain bacteria with UV light so that they produce more cellulose. The basis for this is a new approach with which the researchers generate thousands of bacterial variants and select those that have developed into the most productive.
Published MicroRNA study sets stage for crop improvements
(via sciencedaily.com) Original source MicroRNAs can make plants more capable of withstanding drought, salinity, pathogens and more. However, in a recent study scientists showed just how much we didn't know about the intricate processes plants use to produce them.
Published Fetal brain impacted when mom fights severe flu: New mouse study explains how
(via sciencedaily.com) Original source New research using live mouse-adapted influenza virus improves upon previous mouse experiments to explain how maternal infection impacts fetal brain development. The study also indicates fetal brain changes are more likely once the severity of the mother's infection meets a specific threshold.
Published Researchers decipher new molecular mechanisms related to biological tissue regeneration
(via sciencedaily.com) Original source A study opens new perspectives to better understand how the molecular mechanisms involved in regenerative medicine work. The study focuses on tumor necrosis factor- (TNF- ) and its receptors TNFR, molecules of key interest in biomedicine due to their involvement in multiple diseases such as obesity related to type 2 diabetes mellitus, inflammatory bowel disease and several types of cancer.
Published The ancestor of all modern birds probably had iridescent feathers
(via sciencedaily.com) Original source Birds tend to be more colorful in the tropics, and scientists wanted to find out how they got there: if colorful feathers evolved in the tropics, or if tropical birds have brightly-colored ancestors that came to the region from somwhere else. Scientists built a database of 9,409 birds to explore the spread of color across the globe. They found that iridescent, colorful feathers originated 415 times across the bird tree of life, and in most cases, arose outside of the tropics -- and that the ancestor of all modern birds likely had iridescent feathers, too.
Published Lampreys possess a 'jaw-dropping' evolutionary origin
(via sciencedaily.com) Original source Lampreys are one of only two living jawless vertebrates Jaws are formed by a key stem cell population called the neural crest New research reveals the gene regulatory changes that may explain morphological differences between jawed and jawless vertebrates.
Published New drug shows promise in clearing HIV from brain
(via sciencedaily.com) Original source An experimental drug originally developed to treat cancer may help clear HIV from infected cells in the brain, according to a new study. By targeting infected cells in the brain, drug may clear virus from hidden areas that have been a major challenge in HIV treatment.
Published Ancient marine animal had inventive past despite being represented by few species
(via sciencedaily.com) Original source Brachiopods were evolving in new directions but this did not turn into evolutionary success in terms of the numbers of species, researchers have found.
Published Exploring consciousness with eureka moments
(via sciencedaily.com) Original source We all know what it's like when the penny suddenly drops. Animals too experience such moments of insight. They could prove useful for research of consciousness.
Published Rock art and archaeological record reveal humans' complex relationship with Amazonian animals
(via sciencedaily.com) Original source Rock art explored by archaeologists in the Colombian Amazon has provided an insight into the complex relationship between the earliest settlers on the continent and the animals they encountered.
Published In clinical trial, fecal matter transplant helped half of patients with gastrointestinal cancers overcome resistance to immunotherapy treatment
(via sciencedaily.com) Original source Findings from a small, proof-of-concept clinical trial have suggested that fecal microbiota transplants (FMTs) can boost the effectiveness of immunotherapy in a range of gastrointestinal cancers. In the study, six of 13 patients who had previously shown resistance to immune checkpoint inhibitors benefited from receiving FMTs from donors who had previously responded to treatment. The investigators also identified specific strains of bacteria associated with better or worse responses to FMT and immune checkpoint drugs.
Published It's got praying mantis eyes
(via sciencedaily.com) Original source The praying mantis is one of the few insects with compound eyes and the ability to perceive 3D space. Engineers are replicating their visual systems to make machines see better.
