Efficient generations of complex vectorial optical fields with metasurfaces
Vectorial optical fields (VOFs) exhibiting arbitrarily designed wave-fronts and polarization distributions are highly desired in photonics. To efficiently generate arbitrary VOFs, scientists in China proposed a generic approach based on metasurfaces.....»»
Supergene research solves the mystery of tiny ant queens
An ant colony is sustained through complex social dynamics, with each member—the queen, males and workers (sterile females)—contributing to the greater community. Some species add complexity to this dynamic with the addition of rather small queen.....»»

Team modulates electronic state of single-atom catalysts by CO molecular decoration for efficient methane conversion
Direct methane conversion has advantages such as low energy consumption, fewer processes, and better economics. However, it is difficult to activate methane at room temperature due to the high dissociation energy of C-H bonds of methane. Additionally.....»»
New computational technique enhances accuracy of measurements in nuclear geoscience
Conventional nuclear measurement techniques, such as Monte Carlo simulations, are known for their extensive computational demands and prolonged processing times, especially when applied to unconventional reservoirs characterized by complex lithologie.....»»
A nanoscale look at how shells and coral form reveals that biomineralization is more complex than imagined
Exactly how does coral make its skeleton, a sea urchin grow a spine, or an abalone form the mother-of-pearl in its shell? A new study at the Advanced Light Source at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) reve.....»»
New NASA software simulates science missions for observing terrestrial freshwater
From radar instruments smaller than a shoebox to radiometers the size of a milk carton, there are more tools available to scientists today for observing complex Earth systems than ever before. But this abundance of available sensors creates its own u.....»»
Using mode-locked lasers to realize and study non-Hermitian topological physics
Mode-locked lasers are advanced lasers that produce very short pulses of light, with durations ranging from femtoseconds to picoseconds. These lasers are widely used to study ultrafast and nonlinear optical phenomena, but they have also proved useful.....»»
