Optimality in self-organized molecular sorting
The eukaryotic cell is the basic unit of animals and plants. Through the microscope, it looks highly structured and subdivided in many membrane-bound compartments. Each compartment has a specific function, and its membrane is populated by specific mo.....»»
Euchromatin is not really open in living cells, shows study
DNA and associated proteins in active regions of the genome are condensed but behave like a viscous liquid at the molecular level. This finding greatly increases our understanding of the physical nature of expressed genome regions in living human cel.....»»
How were amino acids, one of the key building blocks of life, formed before the origin of life on Earth?
Our solar system formed from a molecular cloud, which was composed of gas and dust that was emitted into the interstellar medium (ISM), a vast space between stars. On collapse of the molecular cloud, the early sun was formed, with a large disk of gas.....»»
Team proposes an archetype specimen for all dingoes
A taxidermy-prepared dingo named Cooinda has been proposed to serve as an "archetype" specimen for all dingoes. A newly published article provides detailed information on this individual, including a high-quality genome sequence, other molecular biol.....»»
Molecular precursors to life discovered in the Perseus Cloud
Susan Iglesias-Groth, of the Instituto de Astrofísica de Canarias (IAC) and Martina Marín-Dobrincicof the Polytechnic University of Cartagena have discovered the presence of numerous prebiotic molecules in the star formation region IC348 of the Per.....»»
A new model predicts the flexibility of DNA movement at the molecular scale
In both physics and chemistry, the mesoscopic scale refers to the length scale on which the properties of a material or phenomenon can be studied, without entering into a discussion about the behavior of individual atoms. In a mesoscopic model, atomi.....»»
Development of biosensor for real-time detection of the G-protein molecular switch
A research team led by Professor Byung-Chang Suh has investigated the real-time effect of the G-protein cycle, which acts as a switch in the body, on the structural changes in G protein-coupled receptors (GPCRs). Their study is published in the journ.....»»
Study finds degree of asexual reproduction in liverwort plants is hormonally controlled
Asexual, or vegetative, reproduction in plants is controlled by environmental conditions, but the molecular signaling pathways that control this process are poorly understood. Recent research suggests that the KAI2-ligand (KL) hormone is responsible.....»»
"Cold stream" of molecular gas outside a galaxy observed, confirming theories of star formation
An international team of space scientists has observed a "cold stream" of molecular gas outside of a galaxy, confirming theories of star formation within galaxies. In their study, published in the journal Science, the group used the array of radio te.....»»
Researchers reveal structural basis of plp2-mediated cytoskeletal protein folding by TRiC/CCT
In a study published in Science Advances, Dr. Cong Yao's team from the Center for Excellence in Molecular Cell Science, Shanghai Institute of Biochemistry and Cell Biology of the Chinese Academy of Sciences, reported a complete picture of TRiC-assist.....»»
"Taffy Galaxies" collide, leave behind bridge of star-forming material
Galaxy collisions are transformative events, largely responsible for driving the evolution of the universe. The mixing and mingling of stellar material is an incredibly dynamic process that can lead to the formation of molecular clouds populated with.....»»
Understanding how cohesin makes DNA loops in the human genome and its role in Cornelia de Lange syndrome
Cohesin is a ring-shaped protein that surrounds and moves around the DNA molecule, forming the loops. It is a crucial process for the cell. Understanding how cohesin works has been one of the challenges of molecular biology in recent decades. A study.....»»
Advancing drug discovery through multitask learning techniques
A team of researchers from the Skolkovo Institute of Science and Technology, the University of Vienna, and Sirius University of Science and Technology has published a study in the Journal of Computer-Aided Molecular Design that presents guidelines fo.....»»
Scientists develop model for more efficient simulations of protein interactions linked to cancer
Lawrence Livermore National Laboratory scientists have developed a theoretical model for more efficient molecular-level simulations of cell membranes and their lipid-protein interactions, part of a multi-institutional effort to better understand the.....»»
IC Design White Paper puts Chinese mature node capability under spotlight
At the Taiwan IC Design Industrial Policy White Paper Presentation on March 28, co-organized by Taiwan Semiconductor Industry Association (TSIA), DIGITIMES, and MediaTek, leaders from Taiwan's chip design industry convened to gain a glimpse into the.....»»
Scientists use serial crystallography to enhance "molecular movies" and shed light on antibiotic resistance
Eadweard Muybridge's electrifying photos of a galloping horse set the world on fire when he created the precursor to what became motion pictures. For today's scientists, a new upgrade to one of the world's most powerful hard X-ray light sources could.....»»
Review: Bowers & Wilkins’ new Pi7 S2 earbuds deliver my favorite hi-fi listening experience yet
Last I checked in on the true wireless earbuds front, I was taking a look at all of the options from last year and sorting through the best of the best to pick some favorites. And while I praised plenty of offerings from 2022 for having unique featu.....»»
Molecular scale structure and kinetics of layer-by-layer peptide self-organization at atomically flat solid surfaces
In a study recently published in the journal ACS Nano, researchers from Kanazawa University, Kanazawa, Japan, collaborating with University of Washington, Seattle, U.S., used frequency modulated atomic force microscopy to reveal the molecular archite.....»»
RNA vaccination in rabbit mothers confers benefits to offspring in the womb, shows study
Newly developed mRNA vaccines against Zika virus and HIV-1 produced strong antibody responses that transferred from pregnant rabbits to their offspring, researchers report in the journal Molecular Therapy. As noted by the authors, the results support.....»»
