Published Meet the hybrid micro-robot: The tiny robot that is able to navigate in a physiological environment and capture targeted damaged cells


Researchers have developed a hybrid micro-robot, the size of a single biological cell (about 10 microns across), that can be controlled and navigated using two different mechanisms -- electric and magnetic. The micro-robot is able to navigate between different cells in a biological sample, distinguish between different types of cells, identify whether they are healthy or dying, and then transport the desired cell for further study, such as genetic analysis.
Published New type of entanglement lets scientists 'see' inside nuclei


Nuclear physicists have found a new way to see inside nuclei by tracking interactions between particles of light and gluons. The method relies on harnessing a new type of quantum interference between two dissimilar particles. Tracking how these entangled particles emerge from the interactions lets scientists map out the arrangement of gluons. This approach is unusual for making use of entanglement between dissimilar particles -- something rare in quantum studies.
Published Photosynthesis: Varying roads lead to the reaction center


Chemists use high-precision quantum chemistry to study key elements of super-efficient energy transfer in an important element of photosynthesis.
Published AI 'brain' created from core materials for OLED TVs


A research team develops semiconductor devices for high-performance AI operations by applying IGZO materials widely used in OLED displays.
Published At least 80% of the world's most important sites for biodiversity on land currently contain human developments


At least 80% of sites identified as being internationally important for biodiversity on land currently contain infrastructure -- of which more than 75% contain roads. In the future, more sites that are important for biodiversity could contain powerplants, mines and oil and gas infrastructure.
Published Visualizing spatial distribution of electric properties at microscales with liquid crystal droplets


Existing sensor probes for microelectrical devices can measure only their average electric properties, providing no information on their spatial distribution. Liquid crystal droplets (LCDs) -- microscopic droplets of soft matter that respond to electric field -- are promising in this regard. Accordingly, researchers recently visualized the electric field and electrostatic energy distribution of microstructured electrodes by recording the motion of LCDs under an applied voltage, making for high detection accuracy and spatial resolution.
Published Tackling counterfeit seeds with 'unclonable' labels


As a way to reduce seed counterfeiting, researchers developed a silk-based tag that, when applied to seeds, provides a unique code that cannot be duplicated.
Published Researchers create artificial enzyme for fast detection of disease-related hormone in sweat


Researchers have developed a handheld sensor that tests perspiration for cortisol and provides results in eight minutes, a key advance in monitoring a hormone whose levels are a marker for many illnesses including various cancers.
Published Photosynthesis 'hack' could lead to new ways of generating renewable energy


Researchers have 'hacked' the earliest stages of photosynthesis, the natural machine that powers the vast majority of life on Earth, and discovered new ways to extract energy from the process, a finding that could lead to new ways of generating clean fuel and renewable energy.
Published Simulated terrible drivers cut the time and cost of AV testing by a factor of one thousand


The push toward truly autonomous vehicles has been hindered by the cost and time associated with safety testing, but a new system shows that artificial intelligence can reduce the testing miles required by 99.99%.
Published Semiconductor lattice marries electrons and magnetic moments


A model system created by stacking a pair of monolayer semiconductors is giving physicists a simpler way to study confounding quantum behavior, from heavy fermions to exotic quantum phase transitions.
Published New invention: The oxygen-ion battery


An oxygen-ion-battery has been invented, based on ceramic materials. If it degrades, it can be regenerated, therefore it potentially has an extremely long lifespan. Also, it does not require any rare elements and it is incombustible. For large energy storage systems, this could be an optimal solution.

New method to study the movement, behaviour, and environmental context of group-living animals using drones and computer vision.
Published New simulation reveals secrets of exotic form of electrons called polarons


Conditions mapped for the first time of polaron characteristics in 2D materials. TACC's Frontera supercomputer generated quantum mechanical calculations on hexagonal boron nitride system of 30,000 atoms.
Published New research suggests peer-advisor relationship is key to success


Collaborative research across the country has shown that strengthening the relationship between the student and advisor can increase retention rates in engineering doctoral studies.
Published Cracking the concrete code


New research introduces metamaterial concrete for the development of smart civil infrastructure systems. Researchers present a new concept for lightweight and mechanically-tunable concrete systems that have integrated energy harvesting and sensing functionality.
Published Uracil found in Ryugu samples


Samples from the asteroid Ryugu collected by the Hayabusa2 mission contain nitrogenous organic compounds, including the nucleobase uracil, which is a part of RNA.
Published Synthesis gas and battery power from sunlight energy


Plants use photosynthesis to harvest energy from sunlight. Now researchers have applied this principle as the basis for developing new sustainable processes which in the future may produce syngas (synthetic gas) for the large-scale chemical industry and be able to charge batteries.
Published Imaging the proton with neutrinos


The interactions of the quarks and gluons that make up protons and neutrons are so strong that the structure of protons and neutrons is difficult to calculate from theory and must be instead measured experimentally. Neutrino experiments use targets that are nuclei made of many protons and neutrons bound together. This complicates interpreting those measurements to infer proton structure. By scattering neutrinos from the protons that are the nuclei of hydrogen atoms in the MINERvA detector, scientists have provided the first measurements of this structure with neutrinos using unbound protons.
Published 'Y-ball' compound yields quantum secrets


Scientists investigating a compound called 'Y-ball' -- which belongs to a mysterious class of 'strange metals' viewed as centrally important to next-generation quantum materials -- have found new ways to probe and understand its behavior.
