Published Condensed matter physics: Novel one-dimensional superconductor
(via sciencedaily.com) Original source In a significant development in the field of superconductivity, researchers have successfully achieved robust superconductivity in high magnetic fields using a newly created one-dimensional (1D) system. This breakthrough offers a promising pathway to achieving superconductivity in the quantum Hall regime, a longstanding challenge in condensed matter physics.
Published Researchers create artificial cells that act like living cells
(via sciencedaily.com) Original source Researchers describe the steps they took to manipulate DNA and proteins -- essential building blocks of life -- to create cells that look and act like cells from the body. This accomplishment, a first in the field, has implications for efforts in regenerative medicine, drug delivery systems and diagnostic tools.
Published AI tool creates 'synthetic' images of cells for enhanced microscopy analysis
(via sciencedaily.com) Original source Researchers have developed a method to use an image generation AI model to create realistic images of single cells, which are then used as 'synthetic data' to train an AI model to better carry out single-cell segmentation.
Published Scientists discover the cellular functions of a family of proteins integral to inflammatory diseases
(via sciencedaily.com) Original source In a scientific breakthrough, researchers have revealed the biological mechanisms by which a family of proteins known as histone deacetylases (HDACs) activate immune system cells linked to inflammatory bowel disease (IBD) and other inflammatory diseases.
Published Protein network dynamics during cell division
(via sciencedaily.com) Original source An international team has mapped the movement of proteins encoded by the yeast genome throughout its cell cycle. This is the first time that all the proteins of an organism have been tracked across the cell cycle, which required a combination of deep learning and high-throughput microscopy.
Published Magnetic with a pinch of hydrogen
(via sciencedaily.com) Original source Magnetic two-dimensional materials consisting of one or a few atomic layers have only recently become known and promise interesting applications, for example for the electronics of the future. So far, however, it has not been possible to control the magnetic states of these materials well enough. A research team is now presenting an innovative idea that could overcome this shortcoming -- by allowing the 2D layer to react with hydrogen.
Published More economical and sustainable rechargeable batteries
(via sciencedaily.com) Original source Lithium salts make batteries powerful but expensive. An ultralow-concentration electrolyte based on the lithium salt LiDFOB may be a more economical and more sustainable alternative. Cells using these electrolytes and conventional electrodes have been demonstrated to have high performance. In addition, the electrolyte could facilitate both production and recycling of the batteries.
Published New compound from blessed thistle promotes functional nerve regeneration
(via sciencedaily.com) Original source Blessed thistle (Cnicus benedictus) is a plant in the family Asteraceae. For centuries, it has been used as a medicinal herb as an extract or tea, e.g. to aid the digestive system. Researchers have now found a completely novel use for Cnicin. Animal models as well as human cells have shown that Cnicin significantly accelerates axon (nerve fibers) growth.
Published Development of organic semiconductors featuring ultrafast electrons
(via sciencedaily.com) Original source Collaboration has led to the successful observation of these ultrafast electrons within conducting two-dimensional polymers.
Published Light show in living cells
(via sciencedaily.com) Original source Observing proteins precisely within cells is extremely important for many branches of research but has been a significant technical challenge -- especially in living cells, as the required fluorescent labeling had to be individually attached to each protein. The research group has now overcome this hurdle: With a method called 'vpCells,' it is possible to label many proteins simultaneously, using five different fluorescent colors.
Published Octopus inspires new suction mechanism for robots
(via sciencedaily.com) Original source A new robotic suction cup which can grasp rough, curved and heavy stone, has been developed by scientists.
Published Atom-by-atom: Imaging structural transformations in 2D materials
(via sciencedaily.com) Original source Silicon-based electronics are approaching their physical limitations and new materials are needed to keep up with current technological demands. Two-dimensional (2D) materials have a rich array of properties, including superconductivity and magnetism, and are promising candidates for use in electronic systems, such as transistors. However, precisely controlling the properties of these materials is extraordinarily difficult.
Published Solving a mini mystery of cell division
(via sciencedaily.com) Original source Trying to hit a target size before dividing seems like the best strategy for maintaining a precise cell size, but bacteria don't do that. Now we know why.
Published Researchers uncover human DNA repair by nuclear metamorphosis
(via sciencedaily.com) Original source Researchers have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and premature aging.
Published Plastic pollution can kill variety of ocean embryos
(via sciencedaily.com) Original source High levels of plastic pollution can kill the embryos of a wide range of ocean animals, new research shows.
Published A single atom layer of gold: Researchers create goldene
(via sciencedaily.com) Original source For the first time, scientists have managed to create sheets of gold only a single atom layer thick. The material has been termed goldene. According to researchers, this has given the gold new properties that can make it suitable for use in applications such as carbon dioxide conversion, hydrogen production, and production of value-added chemicals.
Published Quantum electronics: Charge travels like light in bilayer graphene
(via sciencedaily.com) Original source An international research team has demonstrated experimentally that electrons in naturally occurring double-layer graphene move like particles without any mass, in the same way that light travels. Furthermore, they have shown that the current can be 'switched' on and off, which has potential for developing tiny, energy-efficient transistors -- like the light switch in your house but at a nanoscale.
Published How tardigrades can survive intense radiation
(via sciencedaily.com) Original source Researchers have discovered that tardigrades -- microscopic animals famed for surviving harsh extremes -- have an unusual response to radiation.
Published Unlocking the 'chain of worms'
(via sciencedaily.com) Original source An international team of scientists has published a single-cell atlas for Pristina leidyi (Pristina), the water nymph worm, a segmented annelid with extraordinary regenerative abilities that has fascinated biologists for more than a century.
Published Cell's 'garbage disposal' may have another role: Helping neurons near skin sense the environment
(via sciencedaily.com) Original source The typical job of the proteasome, the garbage disposal of the cell, is to grind down proteins into smaller bits and recycle some of those bits and parts. That's still the case, for the most part, but researchers, studying nerve cells grown in the lab and mice, say that the proteasome's role may go well beyond that.
