Published Unraveling the mathematics behind wiggly worm knots
(via sciencedaily.com) Original source Researchers wanted to understand precisely how blackworms execute tangling and ultrafast untangling movements for a myriad of biological functions. They researched the topology of the tangles. Their research could inform the design of fiber-like, shapeshifting robotics that self-assemble and move in ways that are fast and reversible.
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.
Published Scientists demonstrate unprecedented sensitivity in measuring time delay between two photons
(via sciencedaily.com) Original source A team of researchers has demonstrated the ultimate sensitivity allowed by quantum physics in measuring the time delay between two photons. This breakthrough has significant implications for a range of applications, including more feasible imaging of nanostructures, including biological samples, and nanomaterial surfaces, as well as quantum enhanced estimation based on frequency-resolved boson sampling in optical networks.
Published Creating a tsunami early warning system using artificial intelligence
(via sciencedaily.com) Original source Researchers develop an early warning system that combines acoustic technology with AI to immediately classify earthquakes and determine potential tsunami risk. They propose using underwater microphones, called hydrophones, to measure the acoustic radiation produced by the earthquake, which carries information about the tectonic event and travels significantly faster than tsunami waves. The computational model triangulates the source of the earthquake and AI algorithms classify its slip type and magnitude. It then calculates important properties like effective length and width, uplift speed, and duration, which dictate the size of the tsunami.
Published Testing antibiotic resistance with a fast, cheap, and easy method
(via sciencedaily.com) Original source Researchers have developed a novel and highly efficient method for rapid antibiotic susceptibility testing using optical microscopy. The technique, called Optical Nanomotion Detection, is extremely rapid, single-cell sensitive, label-free, and requires only a basic traditional optical microscope, equipped with a camera or a mobile phone.
Published Vaccine printer could help vaccines reach more people
(via sciencedaily.com) Original source Researchers have designed a tabletop-sized vaccine printer that could be scaled up to produce hundreds of vaccine doses in a day and deployed anywhere vaccines are needed. The vaccine doses are contained within microneedle patches that can be stored long-term at room temperature and applied to the skin, avoiding the need for injections.
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 Researchers use AI to discover new planet outside solar system
(via sciencedaily.com) Original source A research team has confirmed evidence of a previously unknown planet outside of our solar system, and they used machine learning tools to detect it. A recent study by the team showed that machine learning can correctly determine if an exoplanet is present by looking in protoplanetary disks, the gas around newly formed stars. The newly published findings represent a first step toward using machine learning to identify previously overlooked exoplanets.
Published New programmable smart fabric responds to temperature and electricity
(via sciencedaily.com) Original source A new smart material is activated by both heat and electricity, making it the first ever to respond to two different stimuli.
Published Nanowire networks learn and remember like a human brain
(via sciencedaily.com) Original source Scientists have demonstrated nanowire networks can exhibit both short- and long-term memory like the human brain.
Published New tool facilitates clinical interpretation of genetic information
(via sciencedaily.com) Original source Despite the increasing use of genomic sequencing in clinical practice, interpreting rare genetic mutations, even among well-studied disease genes, remains difficult. Current predictive models are useful for interpreting those mutations, but they are prone to misclassify those that do not cause diseases, contributing to false positives.
Published Do higher-order interactions promote synchronization?
(via sciencedaily.com) Original source A new article shows how the choice of network representation can influence the observed effects. Their work focuses on the phenomenon of synchronization, which emerges in systems from circadian clocks to vascular networks.
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.
