Published Nearly dead plants brought back to life: Keys to aging hidden in the leaves
(via sciencedaily.com) Original source Scientists have known about a particular organelle in plant cells for over a century. However, scientists have only now discovered that organelle's key role in aging.
Published Origin of intense light in supermassive black holes and tidal disruption events revealed
(via sciencedaily.com) Original source A new study is a significant breakthrough in understanding Tidal Disruption Events (TDEs) involving supermassive black holes. The new simulations accurately replicate the entire sequence of a TDE from stellar disruption to the peak luminosity of the resulting flare.
Published Astronomers detect oldest black hole ever observed
(via sciencedaily.com) Original source Researchers have discovered the oldest black hole ever observed, dating from the dawn of the universe, and found that it is 'eating' its host galaxy to death.
Published The metalens meets the stars
(via sciencedaily.com) Original source Researchers have developed a 10-centimeter-diameter glass metalens that can image the sun, the moon and distant nebulae with high resolution. It is the first all-glass, large-scale metalens in the visible wavelength that can be mass produced using conventional CMOS fabrication technology.
Published Study throws our understanding of gene regulation for a loop
(via sciencedaily.com) Original source To function properly, the genetic material is highly organized into loop structures that often bring together widely separated sections of the genome critical to the regulation of gene activity. Scientists now address how these loops can help repress or silence gene activity, with potentially far-reaching effects on human health.
Published Machine learning reveals sources of heterogeneity among cells in our bodies
(via sciencedaily.com) Original source A team of scientists discovered the secrets of cell variability in our bodies. The findings of this research are expected to have far-reaching effects, such as improvement in the efficacy of chemotherapy treatments, or set a new paradigm in the study of antibiotic-resistant bacteria.
Published Glowing COVID-19 diagnostic test prototype produces results in one minute
(via sciencedaily.com) Original source Cold, flu and COVID-19 season brings that now-familiar ritual: swab, wait, look at the result. But what if, instead of taking 15 minutes or more, a test could quickly determine whether you have COVID-19 with a glowing chemical? In a new study, researchers describe a potential COVID-19 test inspired by bioluminescence. Using a molecule found in crustaceans, they have developed a rapid approach that detects SARS-CoV-2 protein comparably to one used in vaccine research.
Published Study delivers detailed photos of galaxies' inner structures
(via sciencedaily.com) Original source High-resolution images captured by the James Webb Space Telescope are offering powerful insights into the complex dust patterns of nearby star-forming galaxies.
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 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 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.
