Real-world mobile phone data suggests a decline in the number of trips people made per day began before state-level stay-at-home policies were implemented, and the decline was strongly correlated with a reduction of COVID-19 case growth in the 25 most affected counties across the USA, according to a modelling study published in The Lancet Infectious Diseases journal.
Artificial light at night attracts insects, thus giving invasive cane toads in places like Australia a lot more food to eat, researchers have found, potentially giving a boost to such invasions.
Scientists at the University of Tsukuba create a theoretical carbon-based material that would be even harder than diamond. This work may have industrial applications for cutting and polishing in place of current synthetic diamond.
The synthesis of silica particles, used in bioimaging and drug delivery, could become considerably cheaper and more efficient by adopting a new flow synthesis method demonstrated by researchers in Australia and China, which involves a spiral channel and simple Teflon pipe to promote the rapid mixing of precursor fluids.
Scientists at The University of Tokyo and Fudan University researched the process of crystallization in which competing structural forms coexist. By compensating for fluctuations, they were able to more accurately describe the process that determines the final crystalline form. This work may help industrial chemists design new methods.
Researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences and Argonne National Laboratory (Argonne) in the U.S. have recently employed atomic layer deposition (ALD) to fabricate visible light-activated membranes that efficiently utilize solar energy.
Rice University physicists discover that plasmonic metals can be prompted to produce "hot carriers" that in turn emit unexpectedly bright light in nanoscale gaps between electrodes. The phenomenon could be useful for photocatalysis, quantum optics and optoelectronics.
In a new study, scientists at Gwangju Institute of Science and Technology developed novel ligand molecules, which facilitate a catalytic reaction that generates useful compounds called chromanones. Chromanones, which have a stereocenter at C2 position (such as gonytolides C and lachnone C), are prominent structural motifs in natural products and possess numerous bioactivities. The newly synthesized ligand molecules offer an effective strategy for generation of chromanones, opening doors to a myriad of applications in drug design.
Method could shed light on nitric oxide's role in the neural, circulatory, and immune systems.
Modeling shows that coral reefs off the east coast of Saudi Arabia have a vital role in protecting the coastal zone.
