Published New aluminium radical battery promises more sustainable power
(via sciencedaily.com) Scientists are hoping to make the world's first safe and efficient non-toxic aqueous aluminum radical battery. Scientists have now reported the first stage of developing these novel batteries.
Published Neutrons look inside working solid-state battery to discover its key to success
(via sciencedaily.com) Original source Researchers have used neutron reflectometry to peer inside a working solid-state battery and monitor its electrochemistry. They discovered that its excellent performance results from an extremely thin layer, across which charged lithium atoms quickly flow as they move from anode to cathode and blend into a solid electrolyte.
Published An ingredient in toothpaste may make electric cars go farther
(via sciencedaily.com) Original source Scientists have developed a fluoride-containing electrolyte for lithium metal batteries that could boost the electric vehicle industry. The usefulness of this electrolyte extends to other types of advanced battery systems beyond lithium ion.
Published Researchers develop digital test to directly measure HIV viral load
(via sciencedaily.com) Original source A milliliter of blood contains about 15 individual drops. For a person with human immunodeficiency virus (HIV), each drop of blood could contain anywhere from fewer than 20 copies of the virus to more than 500,000 copies. Called the viral load, this is what is measured to allow clinicians to understand how patients are responding to anti-viral medications and monitor potential progression. The time-consuming viral load testing needs to be repeated several times as a patient undergoes treatment. Now, a research team has developed a time and cost-efficient digital assay that can directly measure the presence of HIV in single drop of blood.
Published Towards efficient lithium--air batteries with solution plasma-based synthesis of perovskite hydroxide catalysts
(via sciencedaily.com) Original source CoSn(OH)6 (CSO) is an effective oxygen evolution reaction (OER) catalyst, necessary for developing next-generation lithium -- air batteries. However, current methods of synthesizing CSO are complicated and slow. Recently, an international research team synthesized CSO in a single step within 20 minutes using solution plasma to generate CSO nanocrystals with excellent OER catalytic properties. Their findings could boost the manufacturing of high energy density batteries.
Published Extinct warbler's genome sequenced from museum specimens
(via sciencedaily.com) Original source The Bachman's warbler, a songbird that was last seen in North America nearly 40 years ago, was a distinct species and not a hybrid of its two living sister species, according a new study in which the full genomes of seven museum specimens of the bird were sequenced.
Published Drug decelerates bacterial race to antibiotic resistance
(via sciencedaily.com) Original source Researchers report that, in laboratory cultures and animal models, a drug significantly reduces the ability of bacteria to develop antibiotic resistance, which might prolong antibiotic effectiveness.
Published Researcher uses pressure to understand RNA dynamics
(via sciencedaily.com) Original source Just as space holds infinite mysteries, when we zoom in at the level of biomolecules (one trillion times smaller than a meter), there is still so much to learn. Scientists are studying the conformational landscapes of biomolecules and how they modulate cell function. When biomolecules receive certain inputs, it can cause the atoms to rearrange and the biomolecule to change shape. This change in shape affects their function in cells, so understanding conformational dynamics is critical for drug development.
Published The molecular control center of our protein factories
(via sciencedaily.com) Original source Researchers have deciphered a biochemical mechanism that ensures that newly formed proteins are processed correctly when they leave the cell's own protein factories. This solves a decade-old puzzle in protein sorting.
Published The clue is in the glue -- Nature's secret for holding it together
(via sciencedaily.com) Original source An obscure aquatic plant has helped to explain how plants avoid cracking up under the stresses and strains of growth.
Published Studying herpes encephalitis with mini-brains
(via sciencedaily.com) Original source The herpes simplex virus-1 can sometimes cause a dangerous brain infection. Combining an anti-inflammatory and an antiviral could help in these cases, report scientists.
Published Unraveling the connections between the brain and gut
(via sciencedaily.com) Original source Engineers designed a technology to probe connections between the brain and the digestive tract. Using fibers embedded with a variety of sensors, as well as optogenetic stimulation, the researchers could control neural circuits connecting the gut and the brain, in mice.
Published A roadmap for gene regulation in plants
(via sciencedaily.com) Original source For the first time, researchers have developed a genome-scale way to map the regulatory role of transcription factors, proteins that play a key role in gene expression and determining a plant's physiological traits. Their work reveals unprecedented insights into gene regulatory networks and identifies a new library of DNA parts that can be used to optimize plants for bioenergy and agriculture.
