A study of biomass burning aerosols led by University of Wyoming researchers revealed that smoke from wildfires has more of a cooling effect on the atmosphere than computer models assume.

A lurking threat that has stymied US corn growers for decades is now returning to the forefront: western corn rootworm. Sometimes referred to as the "billion-dollar bug," the species' tiny larvae chew through the roots of corn plants, causing devastating yield losses. In 2003, farmers began planting a genetically engineered variety of corn known as "Bt," which produces a protein toxic to the pest...

Each year, thousands of migratory mule deer and pronghorn antelope journey northwest from their winter homes in the Green River Basin, a grassland valley in western Wyoming, to their summer homes in the mountainous landscape near Grand Teton National Park.

Curiosity has been found to play a role in our learning and emotional well-being, but due to the open-ended nature of how curiosity is actually practiced, measuring it is challenging. Psychological studies have attempted to gauge participants' curiosity through their engagement in specific activities, such as asking questions, playing trivia games, and gossiping. However, such methods focus on...

Researchers have found a simple way to eliminate almost all sequencing errors produced by a widely used portable DNA sequencer, potentially enabling scientists working outside the lab to study and track microorganisms like the SARS-CoV-2 virus more efficiently.

Invasive round goby fish have impacted fisheries in the Great Lakes and the Finger Lakes by competing with native species and eating the eggs of some species of game fish.

Scientists have used gene-editing advances to achieve a tenfold increase in the production of super-bug targeting formicamycin antibiotics.

Organizations seeking to fill internal roles traditionally have two options: promote from within or hire externally. Internal promotions benefit from being vetted talent who possess firm-specific skills while outside hires harbor external knowledge that can infuse an organization with new energy. Though this dichotomy is often accepted as unavoidable, there is a third option: boomerang employees.

Photosynthesis, the process by which plants and other organisms convert sunlight into chemical energy, has been a major player during the evolution of life and our planet's atmosphere. Although most of the ins and outs of photosynthesis are understood, how the necessary mechanisms evolved is still a topic of debate. The answer to this question, however, may actually lie buried in the mineral...

How dark is the sky, and what does that tell us about the number of galaxies in the visible universe? Astronomers can estimate the total number of galaxies by counting everything visible in a Hubble deep field and then multiplying them by the total area of the sky. But other galaxies are too faint and distant to directly detect. Yet while we can't count them, their light suffuses space with a...

As the rover has continued to ascend Mount Sharp, it's found distinctive benchlike rock formations.

María Martinón-Torres and José María Bermúdez de Castro, researchers at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), have participated in a study published in the Journal of Human Evolution, on one of the few human fossils known from late Early Pleistocene China, the Meipu teeth, which provides new information on the early settlement of continental Asia.

Current means of fighting bacteria are no longer as good as they used to be because of antibiotic resistance. These days, people are dying from bacterial infections that could have been cured fifty years ago.

During a typical year, over a million people visit Yellowstone National Park, where the Old Faithful geyser regularly blasts a jet of boiling water high in the air. Now, an international team of astronomers has discovered a cosmic equivalent, a distant galaxy that erupts roughly every 114 days.

Most consumers of drinking water in the United States know that chemicals are used in the treatment processes to ensure the water is safe to drink. But they might not know that the use of some of these chemicals, such as chlorine, can also lead to the formation of unregulated toxic byproducts.

Insufficient interactions with advisers and peers, as well as financial problems, are derailing career aspirations of women and minority groups pursing graduate degrees in the nation's highest-funded chemistry programs.

Machine learning and artificial intelligence (AI) are perfectly suited to help companies and marketers monitor and set prices based on real-time dynamic pricing. But new research has identified some possible unintended consequences of AI in this area.

Research on cycad trees in Colombia, Guam, and the Philippines has illuminated how knowledge of their branching behavior may benefit conservation decisions for the endangered plants. In a study published in the December issue of the journal Horticulturae, scientists from the University of Guam and the Montgomery Botanical Center in Florida show that the number of times a cycad tree produces a...

There's an expanded nationwide recall of Sportmix pet food products underway, after links were found between a mold-borne toxin in the food and the deaths of 70 dogs, with 80 other dogs being sickened, the U.S. Food and Drug Administration announced Monday.

Producing clean energy and reducing the power consumption of illumination and personal devices are key challenges to reduce the impact of modern civilization on the environment. As a result, the surging demand for solar cells and light-emitting devices is driving scientists to explore new semiconductor materials and improve their performances, while lowering the production costs.

A team of astronomers led by the University of Arizona has observed a luminous quasar 13.03 billion light-years from Earth—the most distant quasar discovered to date. Dating back to 670 million years after the Big Bang, when the universe was only 5% its current age, the quasar hosts a supermassive black hole equivalent to the combined mass of 1.6 billion suns.

One-third of the fertilizer applied to grow corn in the U.S. each year simply compensates for the ongoing loss of soil fertility, leading to more than a half-billion dollars in extra costs to U.S. farmers every year, finds new research from the University of Colorado Boulder published last month in Earth's Future.

Most flowering plants depend on pollinators such as bees to transfer pollen from the male anthers of one flower to the female stigma of another flower, enabling fertilization and the production of fruits and seeds. Bee pollination, however, involves an inherent conflict of interest, because bees are only interested in pollen as a food source.

Households in Europe and North America are flooding the oceans with plastic pollution simply by washing their clothes, scientists said Tuesday after research found the majority of microplastics in Arctic seawater were polyester fibres.
