Almost all of Africa's maize crop is at risk from the devastating fall armyworm pest (Spodoptera frugiperda) according to new research published in the journal Frontiers in Insect Science.
For thousands of years, crops have been shaped by domestication processes. Farmers cross-breed and select new varieties, adapted to constantly changing environments. Although efficient, this process is time consuming. Moreover, the desired trait must be present somewhere within the diversity of the species to be improved.
Many hospitality organizations see the benefits of engaging in corporate social responsibility (CSR), which can take many forms. Researchers at Surrey aimed to investigate the impact of hiring individuals experiencing houselessness on customers' behavioral intentions, attitudes toward an organization, and perceptions of CSR actions.
Cornell University researchers have found that white-tailed deer—the most abundant large mammal in North America—are harboring SARS-CoV-2 variants that were once widely circulated, but no longer found in humans.
At a time when climate change is making many areas of the planet hotter and drier, it's sobering to think that deserts are relatively new biomes that have grown considerably over the past 30 million years. Widespread arid regions, like the deserts that today cover much of western North America, began to emerge only within the past 5 to 7 million years.
On Jan. 16, 2016, beachgoers up and down the Washington, Oregon and northern California coasts were surprised by multiple "sneaker" waves that inundated beaches, caused injuries and swamped a vehicle.
Science is shaping how Australia can better prepare for devastating bushfire seasons with the release of comprehensive research based on the major issues of the 2019–20 Black Summer fire season.
A University of Central Florida research team with collaborators at Virginia Tech has published critical findings about the electrochemical synthesis of ammonia, advancing sustainable fertilizer research and thus aiding global food safety efforts.
Researchers from Erasmus University Rotterdam and Universite Libre de Bruxelles have published a new study that documents effective yet inexpensive strategies to make fundraising campaigns more effective.
Published today in the journal Environmental Research Letters, a new study investigates the transparency and traceability of cocoa supply chains in Côte d'Ivoire, the world's largest cocoa producer. The results show that less than 45% of cocoa from Côte d'Ivoire can be traced back to the first buyer. The remaining 55% cannot, either because it is indirectly sourced by traders from intermediaries...
Molecular analysis of the eggshell structure of large flightless birds such as ostriches and emus provides new insights into how they evolved.
Astronomers have not yet been able to map large portions of the radio emissions from our universe because of interference from the Earth itself. A team of astronomers hopes to change that, beginning with the LuSEE Night mission to the far side of the moon. It will launch in 2025 and chart a new pathway to Lunar observatories.
It is an exciting time for astronomers and cosmologists. Since the James Webb Space Telescope (JWST), astronomers have been treated to the most vivid and detailed images of the universe ever taken. Webb's powerful infrared imagers, spectrometers, and coronagraphs will allow for even more in the near future, including everything from surveys of the early universe to direct imaging studies of...
Before going to the moon, the Apollo astronauts trained at various sites on Earth that best approximated the lunar surface, such as the volcanic regions Iceland, Hawaii and the U.S. Southwest. To help prepare for upcoming robotic and human Artemis missions, a newly upgraded "mini-moon" lunar testbed will allow astronauts and robots to test out realistic conditions on the moon including rough...
In a recent study published in the journal Icarus, a team of researchers at the International Research School of Planetary Science (IRSPS) located at the D'Annunzio University of Chieti-Pescara in Italy conducted a geological analysis of a region on Neptune's largest moon, Triton, known as Monad Regio to ascertain the geological processes responsible for shaping its surface during its history, and...
The cosmic zoo contains objects so bizarre and extreme that they generate gravitational waves. Scorpius X-1 is part of that strange collection. It's actually a binary pair: a neutron star orbiting with a low-mass stellar companion called V818 Scorpii. The pair provides a prime target for scientists hunting for so-called "continuous" gravitational waves. Those waves should exist, although none have...
Non-native forest tree species can reduce native species diversity if they are planted in uniform stands. In contrast, the effects of introduced species on soil properties are small. This was found by an international review study with the participation of the Swiss Federal Institute for Forest, Snow and Landscape Research WSL.
Advances in molecular biology have revealed that pep-tRNAs—nascent polypeptides inside the ribosome that are covalently attached to transfer RNA—are involved in myriad cell functions, including gene expression. All proteins exist as pep-tRNAs at some point, and studying these translation intermediates is vital as they possess properties of both RNA and protein, and can help researchers better...
Mars displays fascinating geology everywhere you look—and nowhere is this more true than in the fractured, wrinkled ground seen in this image from ESA's Mars Express.
Scientists from the University of Stirling's Institute of Aquaculture and WorldFish have recently published an open-access paper titled "The role of aquaculture and capture fisheries in meeting food and nutrition security: Testing a nutrition-sensitive pond polyculture intervention in rural Zambia" in the journal Foods.
US environmental authorities on Tuesday blocked a huge gold and copper mine project in Alaska's pristine salmon-rich Bristol Bay.
Two emperor tamarin monkeys have gone missing from Dallas Zoo in Texas, with police fearing theft in the latest of a string of bizarre animal incidents at the attraction.
Medical innovations typically take 17 years from the time a lightbulb goes off in a scientist's head until the first person benefits.
Reports of large carnivore attacks on humans have increased since 1970, but the frequency and context of these attacks depends on socioeconomic and environmental factors, according to a new study of more than 5,000 reports published January 31 in the open-access journal PLOS Biology by Giulia Bombieri of MUSE Science Museum in Italy, Vincenzo Penteriani of the National Museum of Natural Science...
Fleas, tapeworms, Giardia, pinworms: Parasites are all around us. But some animals are more susceptible than others. Take the well-studied chimpanzee, for example: it's known to host over 100 parasites. In contrast, species like the indri, a lemur only found on Madagascar, are only known to host about 10 parasites. Many other primates are so poorly studied that only one parasite has ever been...
