(via sciencedaily.com) A new study has found that people can learn to use supernumerary robotic arms as effectively as working with a partner in just one hour of training.
Published Light and sound waves reveal negative pressure
(via sciencedaily.com) Negative pressure is a rare and challenging-to-detect phenomenon in physics. Using liquid-filled optical fibers and sound waves, researchers have now discovered a new method to measure it. In collaboration with the Leibniz Institute of Photonic Technologies in
Published Drug discovery on an unprecedented scale
(via sciencedaily.com) Boosting virtual screening with machine learning allowed for a 10-fold time reduction in the processing of 1.56 billion drug-like molecules. Researchers teamed up with industry and supercomputers to carry out one of the world's largest virtual drug screens.
Published There is much to improve in identifying all the chemicals around us
(via sciencedaily.com) What chemicals are we exposed to on a daily basis? That is the central question of 'non-targeted analysis' or NTA, an emerging field of analytical science that aims to identify all chemicals around us. A daunting task, because how can you be sure to detect everything if you don't know exactly what you're looking for?
Published Unraveling the mysteries of glassy liquids
(via sciencedaily.com) Original source A collaborative study builds a novel theory to explain the puzzling collective behavior of glass-forming liquids at low temperatures, a phenomenon with widespread implications in fields like material science and biology.
Published Researchers develop first method to study microRNA activity in single cells
(via sciencedaily.com) Researchers have developed the first method to uncover the tasks that microRNAs perform in single cells. This is a huge improvement over existing state-of-the-art methods that require millions of cells and will for the first time allow researchers to study microRNAs in complex tissues such as brains.
Published Nanoparticles made from plant viruses could be farmers' new ally in pest control
(via sciencedaily.com) Engineers have devised a new solution to control a major agricultural menace, root-damaging nematodes. Using plant viruses, the researchers created nanoparticles that can deliver pesticide molecules to previously inaccessible depths in the soil. This 'precision farming' approach could potentially minimize environmental toxicity and cut costs for farmers.
Published Shh! Quiet cables set to help reveal rare physics events
(via sciencedaily.com) Newly developed ultra-low radiation cables reduce background noise for neutrino and dark matter detectors.
Published Split gene-editing tool offers greater precision
(via sciencedaily.com) To make a gene-editing tool more precise and easier to control, engineers split it into two pieces that only come back together when a third molecule is added.
Published Making contact: Researchers wire up individual graphene nanoribbons
(via sciencedaily.com) Researchers have developed a method of 'wiring up' graphene nanoribbons (GNRs), a class of one-dimensional materials that are of interest in the scaling of microelectronic devices. Using a direct-write scanning tunneling microscopy (STM) based process, the nanometer-scale metal contacts were fabricated on individual GNRs and could control the electronic character of the GNRs. The researchers say that this is the first demonstration of making metal contacts to specific GNRs with certainty and that those contacts induce device functionality needed for transistor function.
Published Researchers make sand that flows uphill
(via sciencedaily.com) Engineering researchers have discovered that sand can actually flow uphill. A corresponding video shows what happens when torque and an attractive force is applied to each grain -- the grains flow uphill, up walls, and up and down stairs.
Published Let it flow: Recreating water flow for virtual reality
(via sciencedaily.com) A research team has harnessed the power of deep reinforcement learning to replicate the flow of water when disturbed. The replication allowed for recreating water flow in real time based on only a small amount of data, opening up the possibility for virtual reality interactions involving water.
Published Cloud services without servers: What's behind it
(via sciencedaily.com) A new generation of cloud services is on the rise. It is based on the paradigm of 'serverless computing'. A recent article deals with the history, status and potential of serverless computing.
Published Spider silk is spun by silkworms for the first time, offering a green alternative to synthetic fibers
(via sciencedaily.com) Scientists have synthesized spider silk from genetically modified silkworms, producing fibers six times tougher than the Kevlar used in bulletproof vests. The study is the first to successfully produce full-length spider silk proteins using silkworms. The findings demonstrate a technique that could be used to manufacture an environmentally friendly alternative to synthetic commercial fibers such as nylon.
Published Novel organic light-emitting diode with ultralow turn-on voltage for blue emission
(via sciencedaily.com) An upconversion organic light-emitting diode (OLED) based on a typical blue-fluorescence emitter achieves emission at an ultralow turn-on voltage of 1.47 V. The technology circumvents the traditional high voltage requirement for blue OLEDs, leading to potential advancements in commercial smartphone and large screen displays.
Published Tall buildings could be built quicker if damping models were correct, study finds
(via sciencedaily.com) Multi-story buildings are assembled over-cautiously to withstand wind strengths, researchers have found.
Published Imaging the smallest atoms provides insights into an enzyme's unusual biochemistry
(via sciencedaily.com) A team has used neutron crystallography to image all of the atoms in a radical intermediate of a copper amine oxidase enzyme. They disclosed previously unknown details, such as precise conformational changes, that help to explain the enzyme's biochemistry. This work might help researchers engineer enzymes that facilitate unusual chemistry or are highly efficient at room temperature that are useful in chemical industry.
Published Fast-track strain engineering for speedy biomanufacturing
(via sciencedaily.com) Using engineered microbes as microscopic factories has given the world steady sources of life-saving drugs, revolutionized the food industry, and allowed us to make sustainable versions of valuable chemicals previously made from petroleum. But behind each biomanufactured product on the market today is the investment of years of work and many millions of dollars in research and development funding. Scientists want to help the burgeoning industry reach new heights by accelerating and streamlining the process of engineering microbes to produce important compounds with commercial-ready efficiency.
