Recently, a research group led by Prof. Yuan Kaijun and Prof. Yang Xueming from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences revealed strong isotope effects in photodissociation of the water isotopologue (HOD) using the Dalian Coherent Light Source.

Coffee shops and casual restaurants are an important part of American life. Even beyond the food and drinks they sell, they offer us a place to use the restroom or rest our feet while we're out and about, and they provide internet access to those on the go, those in need of a temporary office, or those who don't have an internet connection at home. Many of us take for granted that a nearby Starbucks or McDonald's can offer us a little respite, even if we don't always make a purchase.

The costs of dealing with the coronavirus pandemic have forced Mexican archaeologists to re-bury a unusual find that combined colonial and pre-Hispanic features.

Sixty percent of students in school, college or university felt their opportunities to learn job skills worsened due to the pandemic, according to a new study led by UCL researchers. The percentage remained high even when school and colleges reopened.

Community policing that encourages relationships with local citizens may reduce police violence, while proactive policing strategies are associated with higher police violence, according to new Rutgers University–Camden research.

To win swimming gold in Tokyo, swimmers not only have to generate incredible power with their arms and legs to propel themselves through the water; they also have to overcome the relentless pull of the water's drag while doing so.

As Xi'an Jiaotong-Liverpool University researchers completed their research on colored architectural concrete, they found a surprising result—green pigmented cement had impurities that produced porous, poor quality concrete. Meanwhile, red and blue pigments had little effect.

The United States-Mexico border should be fully reopened—with people on both sides given easier and expanded access to vaccines in the U.S.—according to a new brief from Rice's Baker Institute for Public Policy.

A survey by Massey University's Healthy Work Group of more than 1400 people from 21 New Zealand workplaces has found four key features associated with positive outcomes for both employees and organizations.

About six gigatons—roughly 12 times the mass of all living humans—of carbon appears to be emitted over land every year, according to data from the Chinese Global Carbon Dioxide Monitoring Scientific Experimental Satellite (TanSat).

Drought is withering crops on both sides of the U.S.-Canadian border, prompting farmers to take the rare measure of baling up their wheat and barley stems to sell as hay.

A team of researchers from the Indian Institute of Science Education and Research in Kolkata, the Indian Institute of Technology Kharagpur and RWTH Aachen University, has found a type of piezoelectric molecular crystal that is capable of autonomous self-healing. In their paper published in the journal Science, the group describes their work with piezoelectric molecular crystals and the crystals they grew that could heal themselves.

In a new publication from Opto-Electronic Advances, researchers led by Professor Liu Yan from Xidian University, China and Professor Gan Xuetao from Northwestern Polytechnical University, China, consider generation and application of the high-Q resonance in all-dielectric metasurfaces.

Pandemic-induced lockdowns have provided stories of both hardship and resilience. This extends to families in the community caring for children in out-of-home care, a group which has weathered unique challenges as children are physically and sometimes virtually cut off from contact with their biological families.

University of Georgia researchers have developed a new material with properties ideal for medical products such as masks and bandages. It's also better for the environment than the materials in current use.

Devastating floods destroyed towns in Germany and Belgium. A ruthless heat wave broiled the Western U.S. and Canada. Heavy rains paralyzed a Chinese industrial hub home to 10 million people. These recent weather phenomena are being intensified by the changing climate.

Curved imagers that can adjust their shape could have many valuable applications, for instance, aiding the development of more advanced medical imaging tools and cameras. Most existing flexible curvy imagers, however, are either not compatible with tunable focal surfaces or can only capture images with low resolutions and pixel fill factors.
