Published Engineers tap into good vibrations to power the Internet of Things
(via sciencedaily.com) Original source In a world hungry for clean energy, engineers have created a new material that converts the simple mechanical vibrations all around us into electricity to power sensors in everything from pacemakers to spacecraft.
Published New RNA-seq, metabolomics protocol offers more efficient extraction that maintains data integrity
(via sciencedaily.com) Original source Scientists have developed a new extraction protocol for RNA-seq and metabolomic analysis, offering a more complete picture of cellular activity than either technique on its own. The protocol employs a streamlined extraction from a single sample, which reduces variation, improves efficiency, preserves data fidelity and maximizes use of precious biospecimens.
Published 'Raw' data show AI signals mirror how the brain listens and learns
(via sciencedaily.com) Original source New research shows that artificial intelligence (AI) systems can process signals in a way that is remarkably similar to how the brain interprets speech, a finding scientists say might help explain the black box of how AI systems operate.
Published Deep neural network provides robust detection of disease biomarkers in real time
(via sciencedaily.com) Original source A lab has developed a deep neural network that improves the accuracy of their unique devices for detecting pathogen biomarkers.
Published Self-folding origami machines powered by chemical reaction
(via sciencedaily.com) Original source Scientists have harnessed chemical reactions to make microscale origami machines self-fold -- freeing them from the liquids in which they usually function, so they can operate in dry environments and at room temperature.
Published Quantum entanglement of photons doubles microscope resolution
(via sciencedaily.com) Original source Using a "spooky" phenomenon of quantum physics, researchers have discovered a way to double the resolution of light microscopes.
Published Toys demonstrate how biological machines move
(via sciencedaily.com) Original source By connecting small self-propelling toys in a chain, researchers have found the key to studying the movement of microscopic organisms and molecular motors inside our cells.
Published Better understanding soft material behavior
(via sciencedaily.com) Original source The mechanics behind the collapse of soft materials structure have befuddled researchers for decades. In a new study, researchers uncover a metric that finally correlates microscopic-level processes with what is seen at the macroscopic level.
Published Previously unknown intercellular electricity may power biology
(via sciencedaily.com) Original source Researchers have discovered that the electrical fields and activity that exist through a cell's membrane also exist within and around another type of cellular structure called biological condensates. Like oil droplets floating in water, these structures exist because of differences in density. Their foundational discovery could change the way researchers think about biological chemistry. It could also provide a clue as to how the first life on Earth harnessed the energy needed to arise.
Published Deep-learning system explores materials' interiors from the outside
(via sciencedaily.com) Original source A machine-learning method detects internal structures, voids, and cracks inside a material, based on data about the material's surface.
Published Pulling the plug on viral infections: CRISPR isn't just about cutting
(via sciencedaily.com) Original source CRISPR claimed scientific fame for its ability to quickly and accurately edit genes. But, at the core, CRISPR systems are immune systems that help bacteria protect themselves from viruses. A new study reveals a previously unrecognized player in one such system -- a membrane protein that enhances anti-viral defense. According to study authors, the finding upends the idea that CRISPR systems mount their defense only by degrading RNA and DNA in cells.
Published Can jack-of-all-trades AI reshape medicine?
(via sciencedaily.com) Original source Most medical AI models in use today are trained to perform one or two specific tasks and have limited utility. Next-generation AI -- called generalist medical AI -- incorporates various types of data to perform a variety of complex tasks in a range of clinical scenarios. Generalist medical AI can reshape medicine by augmenting clinical decision-making, real-time surgical and bedside support, and more.
Published Using microbes to get more out of mining waste
(via sciencedaily.com) Original source Researchers have developed a new mining technique which uses microbes to recover metals and store carbon in the waste produced by mining. Adopting this technique of reusing mining waste, called tailings, could transform the mining industry and create a greener and more sustainable future.
Published How spheres become worms
(via sciencedaily.com) Original source A previously unknown form of hydrogel formation has been elucidated: chemists found unusual interactions between polymers.
Published New chemistry can extract virgin-grade materials from wind turbine blades in one process
(via sciencedaily.com) Original source Researchers have developed a chemical process that can disassemble the epoxy composite of wind turbine blades and simultaneously extract intact glass fibers as well as one of the epoxy resin's original building blocks in a high quality. The recovered materials could potentially be used in the production of new blades.
Published A simple paper test could offer early cancer diagnosis
(via sciencedaily.com) Original source Engineers designed a nanoparticle sensor that could enable early diagnosis of cancer with a simple urine test. The sensors, which can detect many cancerous proteins, could also be used to distinguish the type of a tumor or how it is responding to treatment.
Published How a horse whisperer can help engineers build better robots
(via sciencedaily.com) Original source New research shows us that age-old interactions between people and their horses can teach us something about building robots designed to improve our lives.
Published CO2 recycling: What is the role of the electrolyte?
(via sciencedaily.com) Original source The greenhouse gas carbon dioxide can be converted into useful hydrocarbons by electrolysis. The design of the electrolysis cell is crucial in this process. The so-called zero-gap cell is particularly suitable for industrial processes. But there are still problems: The cathodes clog up quickly.
