<p>A small-bird species, the Japanese tit (<em>Parus minor</em>), uses wing movements as a gesture to convey the message “after you,” according to new research at the University of Tokyo. When a mating pair arrives at their nest box with food, they will wait outside on perches. One will then often flutter its wings toward the other, apparently indicating for the latter to enter first. The researchers say that this discovery challenges the previous belief tha...

Tokyo Metropolitan University researchers used boron-nitride nanotubes to create a variety of novel single-walled transition metal dichalcogenide (TMD) nanotubes with varying compositions, chirality, and diameters.

<p>Tokyo, Japan – Researchers from Tokyo Metropolitan University have engineered a range of new single-walled transition metal dichalcogenide (TMD) nanotubes with different compositions, chirality, and diameters by templating off boron-nitride nanotubes. They also realized ultra-thin nanotubes grown inside the template, and successfully tailored compositions to create a family of new nanotubes. The ability to synthesize a diverse range of structures offers unique insights into th...

Research reveals that the molecule cAMP, regulated by the vasoactive intestinal peptide (VIP) in the brain's SCN, is crucial for circadian rhythms, presenting potential new treatments for related health disorders. Circadian rhythms are inherent cycles lasting roughly 24 hours that regulate variou

With the help of a surfactant, scientists from Tokyo Metropolitan University dispersed insulating boron nitride nanotubes and coated them onto surfaces without the need for bundling.

Study reveals the lateral habenula plays a critical role in the priming of aggression in male mice.

The latest findings of a series of studies on mice that examined harmful effects caused by spending time in space show that gene expression related to liver met

Ice core data show why air pollution is dropping more slowly in US and Western Europe despite lower sulfur emissions The air in the United States and Western Europe is much cleaner than even a decade ago. Low-sulfur gasoline standards and regulations on power plants have successfully cut sulfate concentrations in the air, reducing the fine particulate matter that harms human health and cleaning up the environmental hazard of acid rain. Despite these successes, sulfate levels in the atmosphere ...

Ice Core Data Shows Why Air Pollution is Reducing Slower than Sulfur Emissions Reductions Written by AZoCleantechJun 1 2021 Ice core data obtained from Greenland indicates why air pollution has been decreasing slower compared to reductions in sulfur emissions.
