Published Quantum physicists make major nanoscopic advance



In a new breakthrough, researchers have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather than one. Trivial as it may seem to those uninitiated in quantum, this colossal breakthrough allows researchers to create a phenomenon known as quantum mechanical entanglement. This in turn, opens new doors for companies and others to exploit the technology commercially.
Published Scientists observe 'quasiparticles' in classical systems


Quasiparticles -- long-lived particle-like excitations -- are a cornerstone of quantum physics, with famous examples such as Cooper pairs in superconductivity and, recently, Dirac quasiparticles in graphene. Now, researchers have discovered quasiparticles in a classical system at room temperature: a two-dimensional crystal of particles driven by viscous flow in a microfluidic channel. Coupled by hydrodynamic forces, the particles form stable pairs -- a first example of classical quasiparticles, revealing deep links between quantum and classical dissipative systems.
Published AI technology generates original proteins from scratch


Scientists have created an AI system capable of generating artificial enzymes from scratch. In laboratory tests, some of these enzymes worked as well as those found in nature, even when their artificially generated amino acid sequences diverged significantly from any known natural protein.
Published Versatile robo-dog runs through the sandy beach at 3 meters per second


Meet the new addition to the robo-dog family, 'RaiBo', that can run along the sandy beach without losing balance and walk through grassy fields and back on the hard-floored tracking fields all on its own -- no further tinkering necessary.
Published Transistors repurposed as microchip 'clock' address supply chain weakness


A new technique uses standard chip fab methods to fabricate the building block of a timing device, critical to all microprocessors. Currently, this timing device, known as an acoustic resonator, must be produced separately, often overseas, creating a supply chain and security weakness. The technique would allow for this timing device to be integrated with the microprocessor using standard CMOS processing, rather than later bunded with the microprocessor.
Published Person-shaped robot can liquify and escape jail, all with the power of magnets


Inspired by sea cucumbers, engineers have designed miniature robots that rapidly and reversibly shift between liquid and solid states. On top of being able to shape-shift, the robots are magnetic and can conduct electricity. The researchers put the robots through an obstacle course of mobility and shape-morphing tests.
Published Color images from the shadow of a sample


A research team has developed a new method to produce X-ray images in color. In the past, the only way to determine the chemical composition of a sample and the position of its components using X-ray fluorescence analysis was to focus the X-rays and scan the whole sample. This is time-consuming and expensive. Scientists have now developed an approach that allows an image of a large area to be produced from a single exposure, without the need for focusing and scanning.
Published A butterfly flaps its wings and scientists make jewelry


In the 'butterfly effect,' an insect can flap its wings and create a microscopic change in initial conditions that leads to a hurricane halfway around the world. This chaos is seen everywhere, from weather to labor markets to brain dynamics. And now researchers explored how to turn the twisting, fractal structures behind the science into jewelry with 3D printing. The jewelry shapes are based on the Chua circuit, a simple electronic system that was the first physical, mathematical, and experimental proof of chaos.
Published Spin transport measured through molecular films now long enough to develop spintronic devices



A research group has succeeded in measuring spin transport in a thin film of specific molecules -- a material well-known in organic light emitting diodes -- at room temperature. They found that this thin molecular film has a spin diffusion length of approximately 62 nm, a length that could have practical applications in developing spintronics technology. In addition, while electricity has been used to control spin transport in the past, the thin molecular film used in this study is photoconductive, allowing spin transport control using visible light.
Published Click beetle-inspired robots jump using elastic energy


Researchers have made a significant leap forward in developing insect-sized jumping robots capable of performing tasks in the small spaces often found in mechanical, agricultural and search-and-rescue settings. A new study demonstrates a series of click beetle-sized robots small enough to fit into tight spaces, powerful enough to maneuver over obstacles and fast enough to match an insect's rapid escape time.
Published First computational reconstruction of a virus in its biological entirety


A researcher has created a computer reconstruction of a virus, including its complete native genome. Although other researchers have created similar reconstructions, this is believed to be the first to replicate the exact chemical and 3D structure of a 'live' virus.
Published 'Smart' walking stick could help visually impaired with groceries, finding a seat


For people who are blind or visually impaired, finding the right products in a crowded grocery store can be difficult without help. A team of computer scientists is trying to change that.
Published Shedding light on quantum photonics


As buzz grows ever louder over the future of quantum, researchers everywhere are working overtime to discover how best to unlock the promise of super-positioned, entangled, tunneling or otherwise ready-for-primetime quantum particles, the ability of which to occur in two states at once could vastly expand power and efficiency in many applications.
Published Microelectronics give researchers a remote control for biological robots


First, they walked. Then, they saw the light. Now, miniature biological robots have gained a new trick: remote control. The hybrid 'eBiobots' are the first to combine soft materials, living muscle and microelectronics, said researchers.
Published Can you trust your quantum simulator?


Physicists have developed a protocol to verify the accuracy of quantum experiments.
Published Light-based tech could inspire Moon navigation and next-gen farming


Super-thin chips made from lithium niobate are set to overtake silicon chips in light-based technologies, with potential applications ranging from remote ripening-fruit detection on Earth to navigation on the Moon. They say the artificial crystal offers the platform of choice for these technologies due to its superior performance and recent advances in manufacturing capabilities.
Published New small laser device can help detect signs of life on other planets


As space missions delve deeper into the outer solar system, the need for more compact, resource-conserving and accurate analytical tools has become increasingly critical -- especially as the hunt for extraterrestrial life and habitable planets or moons continues. A University of Maryland-led team developed a new instrument specifically tailored to the needs of NASA space missions. Their mini laser-sourced analyzer is significantly smaller and more resource efficient than its predecessors--all without compromising the quality of its ability to analyze planetary material samples and potential biological activity onsite.
Published COVID calculations spur solution to old problem in computer science


A mathematician was keen to forecast the evolution of the COVID epidemic. Instead, he ended up solving a problem which had troubled computer scientists for decades.
Published Clinical trial results indicate low rate of adverse events associated with implanted brain computer interface


There were no safety events that required removal of the device, no infections of the brain or nervous system, and no adverse events resulting in permanently increased disability related to the investigational device.
Published Computers that power self-driving cars could be a huge driver of global carbon emissions



A new model quantifies emissions that will be generated by computers on fully autonomous vehicles. If self-driving cars are widely adopted, their emissions will rival those generated by all the data centers in the world today. Keeping emissions at or below those levels would require hardware efficiency to improve more rapidly than its current pace.
