Published Powering the quantum revolution: Quantum engines on the horizon
(via sciencedaily.com) Original source Scientists unveil exciting possibilities for the development of highly efficient quantum devices.
Published New qubit circuit enables quantum operations with higher accuracy
(via sciencedaily.com) Researchers have developed a novel superconducting qubit architecture that can perform operations between qubits with much higher accuracy than scientists have yet been able to achieve. This architecture, which utilizes a relatively new type of superconducting qubit called fluxonium, is scalable and could be used to someday build a large-scale quantum computer.
Published Crystallization as the driving force
(via sciencedaily.com) Scientists have successfully developed nanomaterials using a so-called bottom-up approach. They exploit the fact that crystals often grow in a specific direction during crystallization. These resulting nanostructures, which appear as 'worm-like and decorated rods,' could be used in various technological applications.
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 Nanofluidic device generates power with saltwater
(via sciencedaily.com) Original source There is a largely untapped energy source along the world's coastlines: the difference in salinity between seawater and freshwater. A new nanodevice can harness this difference to generate power.
Published Efficient training for artificial intelligence
(via sciencedaily.com) New physics-based self-learning machines could replace the current artificial neural networks and save energy.
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 Scaling up the power of nanotechnology
(via sciencedaily.com) Researchers created a proof of concept of a nanocapsule -- a microscopic container -- capable of delivering a specific 'payload' to a targeted location. While beyond the scope of this study, the discovery could one day impact how drugs, nutrients and other types of chemical compounds are delivered within humans or plants.
Published Scientists successfully maneuver robot through living lung tissue
(via sciencedaily.com) Scientists have shown that their steerable lung robot can autonomously maneuver the intricacies of the lung, while avoiding important lung structures.
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 Stabilizing precipitate growth at grain boundaries in alloys
(via sciencedaily.com) Materials are often considered to be one phase, but many engineering materials contain two or more phases, improving their properties and performance. These two-phase materials have inclusions, called precipitates, embedded in the microstructure. Alloys, a combination of two or more types of metals, are used in many applications, like turbines for jet engines and light-weight alloys for automotive applications, because they have very good mechanical properties due to those embedded precipitates. The average precipitate size, however, tends to increase over time-in a process called coarsening-which results in a degradation of performance for microstructures with nanoscale precipitates.
Published 'Garbatrage' spins e-waste into prototyping gold
(via sciencedaily.com) Building on work in human-computer interaction that aims to incorporate sustainability and reuse into the field, researchers introduce 'garbatrage,' a framework for prototype builders centered around repurposing underused devices.
Published Efficient next-generation solar panels on horizon following breakthrough
(via sciencedaily.com) A scientific breakthrough brings mass production of the next generation of cheaper and lighter perovskite solar cells one step closer.
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 Chameleon-inspired coating could cool and warm buildings through the seasons
(via sciencedaily.com) As summer turns to fall, many people will be turning off the air conditioning and firing up heaters instead. But traditional heating and cooling systems are energy intensive, and because they typically run on fossil fuels, they aren't sustainable. Now, by mimicking a desert-dwelling chameleon, a team has developed an energy-efficient, cost-effective coating. The material could keep buildings cool in the summers -- or warm in the winters -- without additional energy.
Published Precisely arranging nanoparticles
(via sciencedaily.com) In the incredibly small world of molecules, the elementary building blocks -- the atoms -- join together in a very regular pattern. In contrast, in the macroscopic world with its larger particles, there is much greater disorder when particles connect. A research team has now succeeded in achieving the same precise arrangement of atoms shown in molecules, but using nanometer-sized particles, known as 'plasmonic molecules' -- combinations of nanoscale metallic structures that have unique properties.
Published Combustion powers bug-sized robots to leap, lift and race
(via sciencedaily.com) Researchers combined soft microactuators with high-energy-density chemical fuel to create an insect-scale quadrupedal robot that is powered by combustion and can outrace, outlift, outflex and outleap its electric-driven competitors.

(via sciencedaily.com) Researchers have developed a way of detecting the early onset of deadly infectious diseases using a test so ultrasensitive that it could someday revolutionize medical approaches to epidemics. The test is an electronic sensor contained within a computer chip. It employs nanoballs -- microscopic spherical clumps made of tinier particles of genetic material -- and combines that technology with advanced electronics.
