As drought- and wind-driven wildfires have become more dangerous across the American West in recent years, firefighters have tried to become smarter in how they prepare.

People may experience respiratory problems because of a persistent bloom of toxic red tide off Florida's Gulf Coast, the National Weather Service said Friday.

People post 500 million tweets and 4 billion pieces of content on Facebook a day. What makes them do it?

Attitudes toward diversity vary, and its meaning can often be difficult to find consensus about in an increasingly diverse but politically polarized nation such as the United States.

Shark Week is many things. First and foremost, it's a week of shark-themed documentary programming on the Discovery Channel. Now in its 33rd year, it's the longest-running cable event in history. It's the biggest audience that marine biologists and ocean conservationists get, attracting millions of viewers who might otherwise not ever think about sharks at all. It's a stage that has launched...

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...

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.

As the SARS-CoV-2 virus that causes COVID-19 continues to evolve, immunologists and infectious diseases experts are eager to know whether new variants are resistant to the human antibodies that recognized initial versions of the virus. Vaccines against COVID-19, which were developed based on the chemistry and genetic code of this initial virus, may confer less protection if the antibodies they...

Electromagnetic (EM) waves in the terahertz (THz) regime contribute to important applications in communications, security imaging, and bio- and chemical sensing. Such wide applicability has resulted in significant technological progress. However, due to weak interactions between natural materials and THz waves, conventional THz devices are typically bulky and inefficient. Although ultracompact...

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.

Humid tropical forests, vital in global efforts to limit rising temperatures, are under threat as a result of changes in land use and climate. Now, researchers reporting in the journal One Earth on July 23 have developed a new way to keep tabs on the vulnerability of these forests on a global scale using satellite data. Called the tropical forest vulnerability index (TFVI), the hope is that this...

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.

Dig a teaspoon into your nearest clump of soil, and what you'll emerge with will contain more microorganisms than there are people on Earth. We know this from lab studies that analyze samples of earth scooped from the microbial wild to determine which forms of microscopic life exist in the world beneath our feet.

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).

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...

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.

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.
