There are often too few flowering plants in agricultural landscapes, which is one reason for the decline of pollinating insects. Researchers at the University of Göttingen have now investigated how a mixture of crops of fava beans (broad beans) and wheat affects the number of pollinating insects. They found that areas of mixed crops compared with areas of single crops are visited equally often by...
A new study of red sea urchins, a commercially valuable species, investigated how different populations respond to changes in their environments. The results show that red sea urchin populations in Northern and Southern California are adapted to their local conditions but differ in their vulnerability to the environmental changes expected to occur in the future due to global climate change and...
High-severity wildfire is increasing in Sierra Nevada and Southern Cascade forests and has been burning at unprecedented rates compared to the years before Euro-American settlement, according to a study from the Safford Lab at the University of California, Davis and its collaborators. Those rates have especially shot up over the past decade.
On the journey from gene to protein, a nascent RNA molecule can be cut and joined, or spliced, in different ways before being translated into a protein. This process, known as alternative splicing, allows a single gene to encode several different proteins. Alternative splicing occurs in many biological processes, like when stem cells mature into tissue-specific cells. In the context of disease,...
There are somewhere between 20 and 74,963 forms of ice because water can do all kinds of weird stuff when it freezes.
A new study by researchers from Durham University, UK, Queen's University Belfast, UK, University of Extremadura, Spain and Swansea University, UK have revealed that vertebrate species involved in the live wildlife trade have distinctive life history traits, biological characteristics that determine the frequency and timing of reproduction.
It's not exactly comforting that the United States is running up against its debt limit, as officials announced this week, nor is there immediate cause for concern for the average taxpayer, says University of Michigan economist Daniil Manaenkov.
Physicists at the University of Bonn have experimentally proven that an important theorem of statistical physics applies to so-called "Bose-Einstein condensates." Their results now make it possible to measure certain properties of the quantum "superparticles" and deduce system characteristics that would otherwise be difficult to observe. The study has now been published in Physical Review Letters.
Intimate partner violence is pervasive in humanitarian settings and its impacts are far-reaching, finds a new study from the Brown School at Washington University in St. Louis.
Mangroves were once seen as inhospitable malarial swamps and were among the fastest disappearing habitats in the world. Now, with input from Bangor University, one community project in Kenya is working to restore mangroves in a project which benefits local communities.
Fourteen whales have washed up on Atlantic Coast beaches since Dec. 1, but marine mammal experts and some conservation groups urge caution before jumping to conclusions about why these animals and others died.
Scientists have advanced in discovering how to use ripples in space-time known as gravitational waves to peer back to the beginning of everything we know. The researchers say they can better understand the state of the cosmos shortly after the Big Bang by learning how these ripples in the fabric of the universe flow through planets and the gas between the galaxies.
In this age of screens, smartphones, virtual assistants, and voice-enabled speakers, we are constantly bombarded by visual and auditory suggestions of things to do, products to buy, and media to consume. Yet are all these messages created equal?
Without barley, hops and yeast, there is no beer. Brewing specialist Dr. Martin Zarnkow and beverage microbiologist Dr. Mathias Hutzler believe that a very special yeast variety might be found in Georgia. So they embarked on a "yeast hunt" and investigated microbiology and brewing traditions in the Caucasus region.
Earth observation, also known as remote sensing, provides highly relevant information about the state and change of our planet every day via satellite data worldwide. The data can be used, for example, to gather information about heat islands in cities, droughts or the condition of forests.
City parks and gardens support a rich and diverse community of soil organisms including bacteria, fungi, protists and invertebrates, which often go unnoticed compared with eye-catching plants and animals.
An Aston University researcher has created the first ever computer reconstruction of a virus, including its complete native genome.
Ever considered the carbon footprint of manufacturing your favorite shirt?
Environmental rules designed to protect imperiled fish in the Sacramento-San Joaquin River Delta have ignited anger among a group of bipartisan lawmakers, who say too much of California's stormwater is being washed out to sea instead of being pumped to reservoirs and aqueducts.
Squinting out the windowed wheelhouse of the ship he's helmed for two decades, Captain Skip Green spots something several hundred yards in the distance.
Researchers at Mount Sinai, in collaboration with researchers at New York University, have published a study in Cell Host & Microbe that sheds light on the mechanisms behind the severity, or virulence, of methicillin-resistant Staphylococcus aureus (MRSA) blood stream infections.
Citizen science projects offer the general public, or segments of that public such as school students, an opportunity to take part in scientific research. The Extreme Energy Events (EEE) Project in Italy is a cooperation between particle physicists studying cosmic rays and school students, and their teachers, throughout the country.
For e-commerce companies, it is cheaper to throw away returned items rather than selling them again. In a new study, researchers at Lund University in Sweden interviewed members of the textile and electronics industries, hoping to better understand a problem that is snowballing, yet has been the subject of little research.
As science and technology advance, we're asking our space missions to deliver more and more results. NASA's MSL Curiosity and Perseverance rovers illustrate this fact. Perseverance is an exceptionally exquisite assemblage of technologies. These cutting-edge rovers need a lot of power to fulfill their tasks, and that means bulky and expensive power sources.
