Many farmers rent bee hives to pollinate crops, but they could tap into the free labor of wild bees by adopting an as-needed approach to pesticides, a new proof-of-concept study shows.

Millions of people in Asia are dependent on rice as a food source. Believed to have been domesticated as early as 6000 BCE, rice is an important source of calories globally. In a new study from the RIPE project, researchers compared domesticated rice to its wild counterparts to understand the differences in their photosynthetic capabilities. The results can help improve future rice productivity.

Researchers at Concordia are studying the potential applications of a type of compound called metal-organic frameworks (MOFs). They have designed a new kind of microscopic structure that can rapidly mitigate chemical weapons when exposed to ultraviolet light.

New research has analyzed a rare collection of non-returning boomerangs from Kinipapa (Cooper Creek), near Innamincka in South Australia's far northeast.

The process of purifying biopharmaceutical drugs remains a costly and time-consuming challenge. A deeper understanding of how unwanted elements within biomanufactured proteins bind to the molecules developed to remove them could help researchers make purity processes more efficient, more complex, and increasingly scalable.

Over the past two centuries, thousands of non-native insects have hitchhiked to the United States in packing material, on live plants, and in passenger baggage. Scientists with two U.S. Department of Agriculture (USDA) agencies and their partners used the history of live plant imports and invasion by a common group of insects to estimate the rate at which new insects are arriving and how many new insect species may yet be in store for U.S. forests and agricultural fields.

Working together, two instruments could open the door for a more efficient, cost-effective way to gather key information for weather forecasting.

An international team of scientists from Austria and Germany has launched a new paradigm in magnetism and superconductivity, putting effects of curvature, topology, and 3D geometry into the spotlight of next-decade research. The results are published in Advanced Materials.

Comets are icy and dusty snowballs of material that have remained relatively unchanged since they first formed billions of years ago. Studying the small bodies provides clues about the formation of the solar system.

Scientists at EMBL Hamburg and CSSB have determined the molecular structure of a gut protein that helps us absorb many drugs. This could help to develop drugs that reach target tissues more efficiently.

While the Doomsday Clock is perilously close to midnight, it is not as close as UK Prime Minister Boris Johnson recently suggested in his COP26 opening remarks.

Over the past 6 years, gravitational wave observatories have been detecting black hole mergers, verifying a major prediction of Albert Einstein's theory of gravity. But there is a problem—many of these black holes are unexpectedly large. Now, a team of researchers from the University of Hawaiʻi at Mānoa, the University of Chicago, and the University of Michigan at Ann Arbor have proposed a novel solution to this problem: Black holes grow along with the expansion of the universe.

Some spent an extra hour a day on chores and childcare during lockdowns, while others got an added daily hour of solo leisure time—and most of us reduced time spent on paid work by around half an hour a day.

Researchers led by Prof. Zhu Maoyan from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NIGPAS) and their collaborators from the UK, the USA, and Russia have proposed new radioisotopic dates for Ediacaran successions in South China and the White Sea area.

Researchers have uncovered new insights into the dynamics that underlie the probabilities of wildfire across the state of California. Isaac Park of the University of California, Santa Barbara, and colleagues present their method and findings in the open-access journal PLOS ONE on November 3, 2021.

Europe's past prosperity and failure, driven by climate changes, has been revealed using thousand-year-old pollen, spores and charcoal particles fossilized in glacial ice. This first analysis of microfossils preserved in European glaciers unveils earlier-than-expected evidence of air pollution and the roots of modern invasive species problems.

As the weather cools in autumn, you may notice the process of condensation, with water droplets forming on windows.

For the first time, researchers from UCL Geography, the University of Nottingham and the UK Centre for Ecology & Hydrology combined large datasets with an environmental flow approach to predict how changes of between 1–3°C in the Earth's temperature would impact 321 of the world's biggest river basins. Collectively, these cover around 50% of the Earth's land surface.

Lean Library today released "Librarian Futures," a white paper based on a large-scale survey of 4,000 librarians and patrons that examines librarian-patron workflows and relationships. The report finds that while patrons are unaware of the full extent of librarian support (with 77% beginning research discovery outside of the library), more than 80% greatly appreciate librarians and would want the library more deeply embedded in their natural workflows.

Different cells make different proteins, and knowledge of these differences could greatly enhance scientists' understanding of the roles of individual cells in healthy tissues and in disease. But obtaining enough protein from a single cell to analyze has been challenging. Now, researchers have developed new methods that could unlock the proteomic secrets of individual cells, according to a cover story in Chemical & Engineering News.

They're born. They live once, erupting for a period that might last for days, years or decades. Then, they go dark and die.

A team of community archaeologists from CITiZAN (the Coastal and Intertidal Archaeological Network) working in partnership with the local community on Mersea Island, Essex, have lifted the lid on the origins of rapid destruction of the island's coastal environment. With funding from the Natural Environment Research Council and the support of Mersea Island Museum, a unique community-led pilot project is helping to shape climate action locally and has the potential to support change on a national and even international level.

Video conferencing played a key role during the COVID-19 pandemic and is set to dominate many meetings in the future. To realize the true feeling of a face-to-face dialog, three dimensional video is required and yet the holographic technology is still missing. Researchers at the University of Stuttgart in Germany have now introduced a completely new approach to realize such dynamic holographic displays, based on electrically switchable plasmonic nanoantennas made from conductive metallic polymers.

New research co-authored by Nicholas Pyenson, curator of fossil marine mammals at the Smithsonian's National Museum of Natural History, shows evidence that the world's largest whales have been sold short. The study, published today in the journal Nature, finds that gigantic baleen whales—such as blue, fin and humpback whales—eat an average of three times more food each year than scientists have previously estimated. By underestimating how much these whales eat, scientists may also have been previously... Читать дальше...

Today, we are experiencing the dramatic impacts that even a small increase in global temperatures can have on a planet's climate. Now, imagine an Earth 20 to 30 degrees Fahrenheit (11 - 17 C) hotter than today. Earth likely experienced these temperatures at various times in the distant past and will experience them again hundreds of millions of years from now as the sun continues to brighten.
