A grim and familiar pattern has followed the parade of mass shootings across America. In their aftermath, the nation's attention focuses on the direct victims of the attacks, the dead and injured, their families and friends, and the witnesses.

During 2020, the use of terms like the "China virus" by public officials and in the media negatively connected COVID-19 to China, where the virus originated, causing a detrimental impact. New research from scholars of the hospitality industry at Penn State and the University of Houston found that this type of virus naming contributed to hostility toward and boycotting of Chinese restaurants and other Asian-related businesses.

A team of scientists from the Department of Energy's Ames National Laboratory has developed a new characterization tool that allowed them to gain unique insight into a possible alternative material for solar cells. Under the leadership of Jigang Wang, senior scientist from Ames Lab, the team developed a microscope that uses terahertz waves to collect data on material samples. The team then used their microscope to explore methylammonium lead iodide (MAPbI3) perovskite, a material that could potentially replace silicon in solar cells.

New University of Minnesota research suggests that while many in the midst of divorce struggle at work, others find renewed career motivation.

A team of researchers from the Group of Neural Circuit in the Graduate School of Science at Nagoya University in central Japan have developed a new method that may help control mosquito populations. The annoying buzzing sound that mosquitoes make when flying inspired this technique.

Layered double hydroxides (LDHs) have a unique structure and many benefits, which have led to them being widely used in fields such as catalysis, environmental management and medical applications. Typically, soluble metal salts, such as metal nitrates, are used as the starting materials for the synthesis of LDHs, but they are relatively expensive and can be inconvenient to store and transport due to their explosive nature.

Just a few hundred feet from where we are sitting is a large metal chamber devoid of air and draped with the wires needed to control the instruments inside. A beam of particles passes through the interior of the chamber silently at around half the speed of light until it smashes into a solid piece of material, resulting in a burst of rare isotopes.

Even though it is over 2,000 years since the ancient Roman road networks were established, there are clear connections between the routes of the roads and modern-day prosperity. In a study in economics, the researchers investigate the importance of the Roman road network in maintaining or losing wealth through the centuries.

As COP27 unfolds in Egypt, we are hearing about a large array of climate change solutions, ranging from building with carbon-absorbing bamboo and using less plastic to growing more kelp in the oceans to retain its carbon stores and enhance biodiversity.

On September 26, 2022, NASA's Double-Asteroid Redirect Test (DART) made history when it rendezvoused with the asteroid Didymos and impacted with its moonlet, Dimorphos. The purpose was to test the kinetic impact method, a means of defense against potentially-hazardous asteroids (PHAs) where a spacecraft collides with them to alter their trajectory. Based on follow-up observations, the test succeeded since DART managed to shorten Dimorphos' orbit by 22 minutes. The impact also caused the moonlet to grow a visible tail.

Spring is here, and with it comes the threat of more floods. Australia is currently experiencing its third consecutive year of a La Niña weather cycle. This means we expect more rainfall than average over the spring and summer months. There is heightened risk of floods, tropical cyclones, prolonged heatwaves and grass fires in southern Australia. This has already led to flooding in parts of the country, and communities are now bracing for more bad weather.

The African Union adopted an agreement more than 13 years ago to prevent the arbitrary displacement of people and to uphold the dignity of such victims.

King Solomon may have gained some of his famed wisdom from an unlikely source—ants.

It's crunch time for diplomats at the United Nations-sponsored COP27 climate conference in Egypt, with dwindling days left to resolve the thorny issue of how poor countries should be compensated for the harm inflicted by global warming they didn't cause.

Published today in the Publications of the Astronomical Society of Australia, the WALLABY (The Widefield ASKAP L-band Legacy All-sky Blind surveY) Pilot Survey will be sharing its first data release with the scientific community, helping us to better understand nearby galaxies and galactic clusters.

Today is the Day of Eight Billion, according to the United Nations.

India will surpass China as the country with the world's largest population in 2023, according to the United Nations World Population Prospects 2022 report.

New technologies often mean elements start moving through the environment in new ways. Take lead plumbing: it helped provide access to fresh water for the masses, but left a toxic legacy that remains to this day.

One of France's five overseas departments, Mayotte is the southernmost island of the Comoros Archipelago, located Indian ocean between Madagascar and the African mainland. The island is the centerpiece of a coral-reef structure that was created over hundreds of thousands of years through volcanic episodes, subsidence and sea-level shifts. Made up of three different structures more than 350 kilometers long, the reef encloses a lagoon with a surface area of 1,100 square kilometers that shelters an... Читать дальше...

A new paper published today in Current Biology presents evidence of a novel and location-specific role of the spliceosome protein SNRNP70. The Houart Group in the Centre for Developmental Neurobiology found that non-nuclear SNRNP70 regulates biological events that control motor function by modifying the diversity of axonal mRNAs.

The rainfall model that engineers use to help them design critical infrastructure such as large dams and nuclear power plants needs to be updated to take into account climate change.

The remains of glyptodonts, a group of extinct giant armadillos, indicate that humans spread to South America earlier than previously assumed. Found in northwestern Venezuela, the fractured skulls could represent evidence of hunting by humans, says UZH paleontologist Marcelo Sánchez. Skilled human hunters are also likely to have contributed to pushing the large, heavily armored animals over the brink.

A new paper shows how the lifespan of the adult honeybee appears to have shrunk by nearly 50% in the past 50 years. The European Red List for Bees suggests nearly one in ten species of wild bees are facing extinction. Imagine how we would react if human lifespans halved. The equivalent would be if the average woman in the UK was living to 41 instead of 82 years old.

Ph.D. candidate astronomer Rob Kavanagh has developed mathematical models to better understand the interactions between exoplanets and stellar winds and to define features of exoplanets.

Ranked as the world's most polluted capital city for four consecutive years, Delhi's dual governance structure involving politically opposed parties has prevented its leaders from agreeing on how to deal with a steadily worsening problem, analysts say.
