Published Researchers reveal an ancient mechanism for wound repair
(via sciencedaily.com) Original source The study is the first to identify a damage response pathway that is distinct from but parallel to the classical pathway triggered by pathogens.
Published Scientists have full state of a quantum liquid down cold
(via sciencedaily.com) Original source A team of physicists has illuminated certain properties of quantum systems by observing how their fluctuations spread over time. The research offers an intricate understanding of a complex phenomenon that is foundational to quantum computing.
Published New biologic effective against major infection in early tests
(via sciencedaily.com) Original source A research team has shown in early tests that a bioengineered drug candidate can counter infection with Staphylococcus aureus -- a bacterial species widely resistant to antibiotics.
Published Better superconductors with palladium
(via sciencedaily.com) Original source A new age of superconductors may be about to beginn: In the 1980s, many superconducting materials (called cuprates) were based on copper. Then, nickelates were discovered -- a new kind of superconducting materials based on nickel. But now, scientists from Austria and Japan have shown: There is a 'Goldilocks zone' of superconductivity which can neither be reached with cuprates nor with nickelates. Instead, palladium-based materials ('palladates') could be the solution.
Published Putting hydrogen on solid ground: Simulations with a machine learning model predict a new phase of solid hydrogen
(via sciencedaily.com) Original source Hydrogen, the most abundant element in the universe, is found everywhere from the dust filling most of outer space to the cores of stars to many substances here on Earth. This would be reason enough to study hydrogen, but its individual atoms are also the simplest of any element with just one proton and one electron.
Published Researchers reveal a map to study novel form of cell-to-cell communication
(via sciencedaily.com) Original source An international team of researchers lays the foundation to examine how extracellular RNA and its carrier proteins found in bodily fluids function in a healthy as well as a diseased setting, potentially providing a means to accurately implement early detection and monitor disease processes.
Published Synthetic biology meets fashion in engineered silk
(via sciencedaily.com) Original source Engineers developed a method to create synthetic spider silk at high yields while retaining strength and toughness using mussel foot proteins.
Published Reinforcement learning: From board games to protein design
(via sciencedaily.com) Original source An AI strategy proven adept at board games like Chess and Go, reinforcement learning, has now been adapted for a powerful protein design program. The results show that reinforcement learning can do more than master board games. When trained to solve long-standing puzzles in protein science, the software excelled at creating useful molecules. In one experiment, proteins made with the new approach were found to be more effective at generating useful antibodies in mice than were previous methods. If this method is applied to the right research problems, it likely could accelerate progress in a variety of scientific fields.
Published Fungal genetics could help develop novel biotechnologies
(via sciencedaily.com) Original source An essential pillar of Earth's ecological system, fungi have long been used to better the lives of humans. While these organisms are still vastly understudied, a new review paper suggests that their unique genomes could be used to make progress in the biotech industry.
Published Engineering the next generation of cell and gene therapies
(via sciencedaily.com) Original source Investigators are developing a novel way to treat amyotrophic lateral sclerosis (ALS) and retinitis pigmentosa using engineered stem cells that may eventually lead to personalized treatments.
Published Quantum entanglement could make accelerometers and dark matter sensors more accurate
(via sciencedaily.com) Original source The 'spooky action at a distance' that once unnerved Einstein may be on its way to being as pedestrian as the gyroscopes that currently measure acceleration in smartphones.
Published Two qudits fully entangled
(via sciencedaily.com) Original source Recently quantum computers started to work with more than just the zeros and ones we know from classical computers. Now a team demonstrates a way to efficiently create entanglement of such high-dimensional systems to enable more powerful calculations.
Published Quantum computer applied to chemistry
(via sciencedaily.com) Original source There are high expectations that quantum computers may deliver revolutionary new possibilities for simulating chemical processes. This could have a major impact on everything from the development of new pharmaceuticals to new materials. Researchers have now used a quantum computer to undertake calculations within a real-life case in chemistry.
Published Embracing variations: Physicists analyze noise in Lambda-type quantum memory
(via sciencedaily.com) Original source In the future, communications networks and computers will use information stored in objects governed by the microscopic laws of quantum mechanics. This capability can potentially underpin communication with greatly enhanced security and computers with unprecedented power. A vital component of these technologies will be memory devices capable of storing quantum information to be retrieved at will.
Published Simple addition to corn bran could boost grain's nutritional value 15-35%
(via sciencedaily.com) Original source What if, by adding a couple of cell layers inside a corn kernel, the grain could become significantly richer in essential nutrients like iron, zinc, and protein? Such an improvement could benefit people who rely on corn for a large portion of their diet, as in many parts of the global south.
Published Study links 'stuck' stem cells to hair turning gray
(via sciencedaily.com) Original source Certain stem cells have a unique ability to move between growth compartments in hair follicles, but get stuck as people age and so lose their ability to mature and maintain hair color, a new study shows.
Published Loops, flags and tension in DNA
(via sciencedaily.com) Original source Two protein complexes carry the major responsibility for the spatial organization of chromosomes in our cell nuclei. DNA tension plays a surprising role in this. Nanoscientists now publish how they have visualized this.
Published New mechanism for DNA folding
(via sciencedaily.com) Original source A hitherto unknown mechanism for DNA folding is described in a new study. The findings provide new insights into chromosomal processes that are vital to both normal development and to prevent disease.
Published Rock, paper, scissors: Searching for stronger nonlocality using quantum computers
(via sciencedaily.com) Original source In the quantum world particles can instantaneously know about each other's state, even when separated by large distances. This is known as nonlocality. Now, A research group has produced some interesting findings on the Hardy nonlocality that have important ramifications for understanding quantum mechanics and its potential applications in communications.
Published Novel nanocages for delivery of small interfering RNAs
(via sciencedaily.com) Original source Small interfering RNAs (siRNAs) are novel therapeutics that can be used to treat a wide range of diseases. This has led to a growing demand for selective, efficient, and safe ways of delivering siRNA in cells. Now, in a cooperation between the Universities of Amsterdam and Leiden, researchers have developed dedicated molecular nanocages for siRNA delivery. In a paper just out in the Journal Chem they present nanocages that are easy to prepare and display tuneable siRNA delivery characteristics.
