Published New technology for conducting deep-sea research on fragile organisms
(via sciencedaily.com) Original source Scientists have successfully demonstrated new technologies that can obtain preserved tissue and high-resolution 3D images within minutes of encountering some of the most fragile animals in the deep ocean.
Published Tests can reveal whether an antibody can turn into a killer
(via sciencedaily.com) Original source A promising antibody failed testing. This is good news for developing a broad-spectrum antidote against the world's most dangerous snake venoms.
Published Astronomers produce most sensitive radio image ever of ancient star cluster
(via sciencedaily.com) Original source Astronomers have created the most sensitive radio image ever of a globular cluster, an ancient ball of tightly-packed stars.
Published Unraveling the role of supersulfides in regulating mitochondrial function and longevity
(via sciencedaily.com) Original source Supersulfides, many of which are produced by cysteinyl-tRNA synthetase (CARS), are essential compounds across many different lifeforms. However, the precise physiological roles of CARS-produced supersulfide are unclear. Now, using a strategically engineered yeast mutant with a deficient CARS gene, researchers from Japan have shown that supersulfides control cell longevity by mediating mitochondrial energy metabolism and regulating protein quality.
Published Discovery changes understanding of water's history on the Moon
(via sciencedaily.com) Original source New research shows the early lunar crust which makes up the surface of the Moon was considerably enriched in water more than 4 billion years ago, counter to previously held understanding.
Published One-step synthesis of the most common, yet highly intricate, antibiotic molecular scaffold
(via sciencedaily.com) Original source Researchers have simplified the operation of an important class of chemical transformation: synthesis of beta-lactams, the intricate scaffold of many antibiotics. Their experimental protocol minimizes the toxicity that is a common feature of similar Fischer-carbene synthetic methodologies, and was used to synthesize the scaffold of the thienamycin antibiotic in high yield. This work is an important advancement in sustainable chemistry that should benefit drug development and other chemical syntheses.
Published Research sheds new light on Moon rock formation solving major puzzle in lunar geology
(via sciencedaily.com) Original source New research has cracked a vital process in the creation of a unique rock type from the Moon. The discovery explains its signature composition and very presence on the lunar surface at all, unraveling a mystery which has long-eluded scientists.
Published Candida evolution disclosed: New insights into fungal infections
(via sciencedaily.com) Original source Identification of genes under recent selection provides insights into the molecular mechanisms of human-related adaptation in Candida pathogens. The study reveals both known and novel genetic variants associated with drug resistance, offering potential targets for improved antifungal therapies.
Published Earth-sized planet discovered in 'our solar backyard'
(via sciencedaily.com) Original source Astronomers have discovered a planet closer and younger than any other Earth-sized world yet identified. It's a remarkably hot world whose proximity to our own planet and to a star like our sun mark it as a unique opportunity to study how planets evolve.
Published Bioinformatics: Researchers develop a new machine learning approach
(via sciencedaily.com) Original source To combat viruses, bacteria and other pathogens, synthetic biology offers new technological approaches whose performance is being validated in experiments. Researchers applied data integration and artificial intelligence (AI) to develop a machine learning approach that can predict the efficacy of CRISPR technologies more accurately than before.
Published Many more infected by TBE virus than previously known
(via sciencedaily.com) Original source The number of infections by the tick-borne TBE virus that are not detected by health services is far higher than previously assumed. This has been shown in a new study of Swedish blood donors.
Published New insights into what helps Salmonella cause infections
(via sciencedaily.com) Original source In a new study, researchers have discovered how a system of proteins, called TamAB, helps Salmonella survive under the harsh conditions inside macrophages.
Published Scientists uncover ocean's intricate web of microbial interactions across depths
(via sciencedaily.com) Original source An international team of scientists has uncovered the ocean's intricate web of microbial interactions across depths. Their research provides crucial insights into the functioning of ocean ecosystems.
Published Researchers create light-powered yeast, providing insights into evolution, biofuels, cellular aging
(via sciencedaily.com) Original source Researchers have engineered one of the world's first yeast cells able to harness energy from light, expanding our understanding of the evolution of this trait -- and paving the way for advancements in biofuel production and cellular aging.
Published New rice lines for Africa offer virus protection
(via sciencedaily.com) Original source The so-called Rice Yellow Mottle Virus (for short: RYMV) is responsible for high crop losses in Africa, particularly among small-scale farmers. A research team has now produced rice lines that are resistant to the disease by means of genome editing. The rice varieties are a preliminary step toward being able to generate resistant locally adapted elite varieties for small-scale food producers in Africa.
Published NASA scientists discover a novel galactic 'fossil'
(via sciencedaily.com) Original source Researchers at NASA's Goddard Space Flight Center have discovered X-ray activity that sheds light on the evolution of galaxies.
Published Antibiotic use is not the only driver of superbugs, research shows
(via sciencedaily.com) Original source Researchers have analyzed the rise of antibiotic resistance over the last 20 years in the UK and Norway, highlighting that antibiotic use is not the only factor in the increase.
Published Even the oldest eukaryote fossils show dazzling diversity and complexity
(via sciencedaily.com) Original source The sun has just set on a quiet mudflat in Australia's Northern Territory; it'll set again in another 19 hours. A young moon looms large over the desolate landscape. No animals scurry in the waning light. No leaves rustle in the breeze. No lichens encrust the exposed rock. The only hint of life is some scum in a few puddles and ponds. And among it lives a diverse microbial community of our ancient ancestors.
Published Close encounters of the supermassive black hole kind
(via sciencedaily.com) Original source Astrophysicists have confirmed the accuracy of an analytical model that can unlock key information about supermassive black holes and the stars they engulf.
Published Our surprising magnetic galaxy
(via sciencedaily.com) Original source A team of astronomers has created the first-ever map of magnetic field structures within a spiral arm of our Milky Way galaxy. Previous studies on galactic magnetic fields only gave a very general picture, but the new study reveals that magnetic fields in the spiral arms of our galaxy break away from this general picture significantly and are tilted away from the galactic average by a high degree. The findings suggest magnetic fields strongly impact star-forming regions which means they played a part in the creation of our own solar system.
