Quantum simulation for 3D chiral topological phase
Professor Liu at PKU, Professor Du and Professor Wang at USTC build up a quantum simulator using nitrogen-vacancy center to investigate a three-dimensional (3D) chiral topological insulator which was not realized in solid state system, and demonstrate a complete study of both the bulk and surface topological physics by quantum quenches.

New approach to soft material flow may yield way to new materials, disaster prediction
How does toothpaste stay in its tube and not ooze out when we remove the cap? What causes seemingly solid ground to suddenly break free into a landslide? Defining exactly how soft materials flow and seize has eluded researchers for years, but a new study explains this complex motion using relatively simple experiments. The ability to define - and eventually predict - soft material flow will benefit people dealing with everything from spreadable cheese to avalanches.

Texas A&M researchers create a contagion model to predict flooding in urban areas
Inspired by the same modeling and mathematical laws used to predict the spread of pandemics, researchers at Texas A&M University have created a model to accurately forecast the spread and recession process of floodwaters in urban road networks. With this new approach, researchers have created a simple and powerful mathematical approach to a complex problem.

Beam me up: Researchers use 'behavioral teleporting' to study social interactions
The team, led by Maurizio Porfiri, Institute Professor at NYU Tandon, devised a novel approach to getting physically separated fish to interact with each other, leading to insights about what kinds of cues influence social behavior. The innovative system, called 'behavioral teleporting,' transfers the complete inventory of behaviors and actions (ethogram) of a live zebrafish onto a remotely located robotic replica swimming with another live fish.

Machine learning peeks into nano-aquariums
In the nanoworld, tiny particles such as proteins appear to dance as they transform and assemble to perform various tasks while suspended in a liquid. Recently developed methods have made it possible to watch and record these otherwise-elusive tiny motions, and researchers now take a step forward by developing a machine learning workflow to streamline the process.

Fuel cells for hydrogen vehicles are becoming longer lasting
An international research team led by the University of Bern has succeeded in developing an electrocatalyst for hydrogen fuel cells which, in contrast to the catalysts commonly used today, does not require a carbon carrier and is therefore much more stable. The new process is industrially applicable and can be used to further optimize fuel cell powered vehicles without CO2 emissions.

Routing valley exciton emission of a WS2 monolayer via in-plane inversion-symmetry broken PhC slabs
The researchers demonstrate all-dielectric photonic crystal (PhC) slabs without in-plane inversion symmetry (C2 symmetry) could separate and route valley exciton emission of a WS2 monolayer at room temperature. Coupling with circularly polarized photonic Bloch modes of such PhC slabs, valley photons emitted by a WS2 monolayer are routed directionally and efficiently separated in the far field. In addition, the far-field emission is directionally enhanced and with long-distance spatial coherence property.

Locust swarm could improve collision avoidance
Plagues of locusts, containing millions of insects, fly across the sky to attack crops, but the individual insects do not collide with each other within these massive swarms. Now a team of engineers is creating a low-power collision detector that mimics the locust avoidance response and could help robots, drones and even self-driving cars avoid collisions.

Psychological disease avoidance linked to preventative behavior, study finds
More than other factors, strong feelings of germ aversion and pathogen disgust are significantly associated with concern about COVID-19 and preventative behavior, according to findings from UConn School of Nursing researchers published in the journal PLOS ONE. The findings are part of a year-long examination of how behavior and social attitudes change, and what factors influence those changes, when people in the United States are faced with the threat of widespread disease.

Research links Southeast Asia megadrought to drying in Africa
Physical evidence found in caves in Laos connects the end of the Green Sahara, when once heavily vegetated Northern Africa became a hyper-arid landscape, and a previously unknown megadrought that crippled Southeast Asia 4,000 to 5,000 years ago. Scientists at the University of California, Irvine, University of Pennsylvania, William Paterson University of New Jersey and other international institutions explain how this major climate transformation led to a shift in human settlement patterns in Southeast Asia.

Using estimation of camera movement to achieve multi-target tracking
Estimating the motion of a moving camera is a ubiquitous problem in the field of computer vision. With technology such as self-driving cars and autonomous drones becoming more popular, fast and efficient algorithms enabling on-board video processing are needed to return timely and accurate information at a low computational cost. This estimation of camera movement, or 'pose estimation', is also a crucial component of target tracking aboard moving vehicles or platforms.

UMass Amherst scientists invent new sensing eye mask
From the team that invented physiology-sensing pajamas at UMass Amherst, now comes a new, lightweight eye mask that can unobtrusively capture pulse, eye movement and sleep signals, for example, when worn in an everyday environment. Senior authors, materials chemist Trisha L. Andrew and computer scientist Deepak Ganesan, say that "being able to track pulse and eye movement in a single wearable device will enable a host of sleep and psycho-social studies.
