(via sciencedaily.com) Original source An interdisciplinary team consisting of researchers has revealed a striking similarity between the memory processing of artificial intelligence (AI) models and the hippocampus of the human brain. This new finding provides a novel perspective on memory consolidation, which is a process that transforms short-term memories into long-term ones, in AI systems.
Published For this emergent class of materials, 'solutions are the problem'
(via sciencedaily.com) Original source Materials scientists developed a fast, low-cost, scalable method to make covalent organic frameworks (COFs), a class of crystalline polymers whose tunable molecular structure, large surface area and porosity could be useful in energy applications, semiconductor devices, sensors, filtration systems and drug delivery.
Published Artificial intelligence can predict events in people's lives
(via sciencedaily.com) Original source Artificial intelligence can analyze registry data on people's residence, education, income, health and working conditions and, with high accuracy, predict life events.
Published Computational model captures the elusive transition states of chemical reactions
(via sciencedaily.com) Original source Researchers developed a way to quickly calculate the transition state structure of a chemical reaction, using machine-learning models.
Published AI study reveals individuality of tongue's surface
(via sciencedaily.com) Original source Artificial Intelligence (AI) and 3D images of the human tongue have revealed that the surface of our tongues are unique to each of us, new findings suggest. The results offer an unprecedented insight into the biological make-up of our tongue's surface and how our sense of taste and touch differ from person to person.
Published Upcycling leftover cardboard to make a new type of foam packaging
(via sciencedaily.com) Original source With the holiday season in full swing, gifts of all shapes and sizes are being shipped around the world. But all that packaging generates lots of waste, including cardboard boxes and plastic-based foam cushioning. Rather than discard those boxes, researchers have developed a cushioning foam from cardboard waste. Their upcycled material was stronger and more insulating than traditional, plastic foam-based cushioning.
Published Researchers find way to weld metal foam without melting its bubbles
(via sciencedaily.com) Original source Researchers have identified a welding technique that can be used to join composite metal foam (CMF) components together without impairing the properties that make CMF desirable. CMFs hold promise for a wide array of applications because the pockets of air they contain make them light, strong and effective at insulating against high temperatures.
Published Cognitive strategies for augmenting the body with a wearable, robotic arm
(via sciencedaily.com) Original source Scientists show that breathing may be used to control a wearable extra robotic arm in healthy individuals, without hindering control of other parts of the body.
Published Researchers create stable hybrid laser by 3D printing micro-optics onto fibers
(via sciencedaily.com) Original source For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive compact and stable laser sources that would be useful in a variety of applications, including the lidar systems used for autonomous vehicles.
Published Towards next-generation nanocatalysts to revolutionize active electron transfer
(via sciencedaily.com) Original source Over the years, scientists have proposed many novel molecular systems for photoinduced electron transfer. Researchers have now developed a copolymer-conjugated nanocatalytic system that can drive efficient photoinduced electron transfer. They employed a temperature-responsive ternary random copolymer and coupled it to platinum nanoparticles. By enabling dynamic electron transfer and driving photoinduced hydrogen generation, this innovation can have far-reaching implications for artificial photosynthesis, electrochemical reactions, macromolecular recognition, and bio-inspired soft materials.
Published Ultra-hard material to rival diamond discovered
(via sciencedaily.com) Original source Scientists have solved a decades-long puzzle and unveiled a near unbreakable substance that could rival diamond, as the hardest material on earth, a study says. Researchers found that when carbon and nitrogen precursors were subjected to extreme heat and pressure, the resulting materials -- known as carbon nitrides -- were tougher than cubic boron nitride, the second hardest material after diamond.
Published Can AI be too good to use?
(via sciencedaily.com) Original source Much of the discussion around implementing artificial intelligence systems focuses on whether an AI application is 'trustworthy': Does it produce useful, reliable results, free of bias, while ensuring data privacy? But a new article poses a different question: What if an AI is just too good?
Published Spinning up control: Propeller shape helps direct nanoparticles
(via sciencedaily.com) Original source Self-propelled nanoparticles could potentially advance drug delivery and lab-on-a-chip systems -- but they are prone to go rogue with random, directionless movements. Now, an international team of researchers has developed an approach to rein in the synthetic particles.
Published Artificial intelligence systems excel at imitation, but not innovation
(via sciencedaily.com) Original source Artificial intelligence (AI) systems are often depicted as sentient agents poised to overshadow the human mind. But AI lacks the crucial human ability of innovation, researchers have found.
Published Scientists 3D print self-heating microfluidic devices
(via sciencedaily.com) Original source A fabrication process can produce self-heating microfluidic devices in one step using a multimaterial 3D printer. These devices, which can be made rapidly and cheaply in large numbers, could help clinicians in remote parts of the world detect diseases without expensive lab equipment.

Published New conductive, cotton-based fiber developed for smart textiles
(via sciencedaily.com) Original source A single strand of newly developed fiber has the flexibility of cotton and the electric conductivity of the polymer, polyaniline. The new material has shown good potential for wearable e-textiles. The researchers tested the fibers with a system that powered an LED light and another that sensed ammonia gas. While intrinsically conductive, polyaniline is brittle and by itself, cannot be made into a fiber for textiles. To solve this, the researchers dissolved cotton cellulose from recycled t-shirts into a solution and the conductive polymer into another separate solution.
