Denver finally got its first snowfall of the season on Friday, shattering an 87-year-old record for the city's latest first snow.

Ellen Wohl has always been fascinated by what happens in the deep sea. She studies interactions between rivers and water, the flow of sediment and wood, and the landforms created as a result.

Oregon State University research into the design of catalysts has shown that hydrogen can be cleanly produced with much greater efficiency and at a lower cost than is possible with current commercially available catalysts.

India is the world's top hot spot for COVID-19 misinformation, accounting for roughly one in six pieces of global output, according to a University of Alberta master's student who studies world media.

In an oceanic omen for climate change's intensifying effects, Cornell-led research shows that seagrass—through large swaths of intertidal meadows in the Pacific Northwest—suffers from a lesion-filled wasting disease. The grasses' once-vibrant plant root systems are deteriorating, too.

The predicted existence of an exotic particle made up of six elementary particles known as quarks by RIKEN researchers could deepen our understanding of how quarks combine to form the nuclei of atoms.

California motorists have been getting their vehicles smog-checked for decades.

Interest in vertical farming is growing worldwide. This method of cultivation offers great advantages: local, fresh production that is possible at any location in a very sustainable way. On the negative side are the high electricity consumption and investment costs. Scientists from Wageningen University & Research, together with international colleagues, provide a balanced view of the current situation in a review article published in the renowned scientific journal Nature Food.

A hedge fund designed to pool money together for the public good could tackle a niche of problems that governments, non-profit organizations and for-profit companies all struggle with solving, according to Penn State researchers.

On the Periodic Table of Elements, there are elements that most people remember from school—oxygen, hydrogen, gold and silver. But there are also the ones that you might not immediately recognize, such as berkelium and einsteinium. These exotic elements are typically only used in specialized laboratories to understand how chemistry and physics change at the extremes of the table.

Growing up in Waukegan, Eduardo Flores didn't think much about the presence of inhalers on his playground.

Like the dark side of the moon, what you cannot see you cannot know. The same holds for floodplains.

When the clock strikes midnight on December 31, one in five large businesses will likely fail to comply to their legal obligations under Australia's Modern Slavery Act (2018), according to new research from the University of South Australia.

With multiple rovers landed and a mission set to return samples to Earth, Mars has dominated the search for life in the solar system for decades. But Venus has some fresh attention coming its way.

When it comes to motherhood, orangutans are animals of distinction. An orangutan mother will stay in close contact with her baby for up to nine years—longer than almost all mammals other than humans. Much like humans, orangutans rely on their mothers to learn life skills—such as what to eat and where to find it—before they finally reach independence almost a decade after birth. But unlike humans, orangutan mothers were not known to participate in their offspring's learning; behaving as passive role models rather than active teachers. Читать дальше...

Many savanna-dependent species in Africa, including large herbivores and apex predators, are at increasing risk of extinction. Estimated costs of achieving effective management of protected areas in Africa where lions live could reach $2 billion (USD) annually. Researchers have now explored the potential for fire management-based carbon-financing programs to fill this funding gap and benefit degrading savanna ecosystems.

With the increasing digitalization in manufacturing industries, companies start to integrate big data analytics into business processes and sell smart services. However, people tend to resist change, remain skeptical about unknown products and technologies and avoid new ways of doing work. According to Valeria Boldosova's doctoral dissertation at the University of Vaasa, Finland, using deliberate storytelling in the workplace might help to deal with these problems.

The National Institute for Materials Science (NIMS) and JEOL, Ltd. have developed a lanthanum hexaboride (LaB6) nanowire-based field emission gun that is installable on an aberration-corrected transmission electron microscope (TEM). This combined unit is able to perform atomic resolution observation at an energy resolution of 0.2 eV—the highest resolution ever recorded for non-monochromatic electron guns—with a high current stability of 0.4%.

A study by the University of Southampton suggests population movement and social mixing rose sharply following the end of the second COVID-19 UK lockdown and then fell away suddenly a few days before Christmas 2020.

It is currently estimated that, worldwide, two out of five plant species are threatened with extinction. Whilst this trend is clearly identifiable at the global scale, there is debate as to whether species richness declines locally. The processes driving this phenomenon—the "biodiversity conservation paradox" as researchers call it, has remained largely unresolved until now. An international team of scientists led by iDiv and MLU has investigated these shifts in species composition in three distinct habitats; mountain summits... Читать дальше...

Turning one of the world's finest gems—diamonds—into one of the worst greenhouse gasses—methane—does not seem a great idea. Yet this happened through the work of a group of researchers from the Universities of Bologna and Edimburgh (UK), the Centre National de la Recherche Scientifique (France) and HPSTAR (China). This outcome published in Nature Communications was not a clumsy lab mistake. In fact, this study might provide more insight on the deep carbon cycle and the formation of hydrocarbons through...

A groundbreaking study led by researchers at Florida Atlantic University and an international team of scientists conclusively confirms the time year of the catastrophic Chicxulub asteroid, responsible for the extinction of dinosaurs and 75 percent of life on Earth 66 million years ago. Springtime, the season of new beginnings, ended the 165-million-year reign of dinosaurs and changed the course of evolution on Earth.

Canadian and American researchers have discovered a new mechanism by which membrane vesicles are made. These self-contained nanoparticles trap proteins, RNA and other molecules from inside or outside of living cells as nutrients or regulate the numbers of cell surface hormone receptors, such as those for insulin, to control the sensitivity of cells to hormones. They also deliver protein hormones to the surface of cells where they are released into the surroundings to act on cells at a distance. These... Читать дальше...

While all atomic nuclei except hydrogen are composed of protons and neutrons, physicists have been searching for a particle consisting of two, three or four neutrons for over half a century. Experiments by a team of physicists of the Technical University of Munich (TUM) at the accelerator laboratory on the Garching research campus now indicate that a particle comprising four bound neutrons may well exist.

New findings of amber in the site of Ariño in Teruel (Spain) have enabled the reconstruction of a swampy paleoenvironment with a rich coastal resin forest from 110 million years ago, from the era of dinosaurs. This place featured conifers and understories of gymnosperms and ferns, and flower plants, where insects, turtles, crocodiles, mammals and dinosaurs such as the species Proa valdearinnoensis and Europelta carbonensis lived.
