Spring bird migration has begun. Under cover of darkness, 2.5–3.5 billion birds will fly northward to their breeding grounds in the United States and Canada. According to the Cornell Lab of Ornithology, now is one of the most important times of year to keep birds safe by reducing non-essential lighting at night and treating window glass so birds can see it and avoid deadly collisions.
Consumers are increasingly health-conscious and seek products with minimal additives and preservatives. The modern consumer understands the link between consuming bioactive compounds from fruits and vegetables and the associated health benefits. Hence, there has been a steady rise in demand for juices made from fresh fruits and vegetables, with minimal processing and no added sugars.
In this image from Feb. 12, 2024, engineers lift a mast into place on NASA's VIPER (Volatiles Investigating Polar Exploration Rover) robotic moon rover. VIPER's mast and the suite of instruments affixed to it look a lot like the rover's "neck" and "head." The mast instruments are designed to help the team of rover drivers and real-time scientists send commands and receive data while the rover navigates around hazardous crater slopes, boulders, and places that risk communications blackouts.
High levels of plastic pollution can kill the embryos of a wide range of ocean animals, new research shows.
The Atlantic surf clam, an economically valuable species that is the main ingredient in clam chowder and fried clam strips, has returned to Virginia waters in a big way, reversing a die-off that started more than two decades ago.
University of Toronto (U of T) scientists have developed a framework for measuring plastic pollution emissions akin to the global standard for measuring greenhouse gas emissions. The researchers say the approach will boost identification of the biggest contributors to plastic pollution from local to national levels and improve strategies in reducing emissions worldwide.
A research team has devised a novel method to prepare carbonized polymer nanodots capable of emitting multi-color ultra-long room-temperature phosphorescence (RTP) from blue to green.
New details have emerged about the history of one of St. Augustine's most popular tourist attractions. University of South Florida Spanish Professor David Arbesú pieced together documents that were scattered around the world that helped connect the dots about the life of Francisco López de Mendoza Grajales, believed to be the first priest in the United States. An 11-foot statue of him is located on the grounds of Mission Nombre de Dios near Matanzas Bay.
Pyrogenic carbon is widely produced during the incomplete combustion of biomass and fossil fuels on land. About one-third of pyrogenic carbon is exported to the ocean by rivers, and thereinto, the refractory fraction becomes the source of oceanic black carbon that can provide a long-term sink for atmospheric CO2.
The length of time that Yellowstone Lake is covered by ice each year has not changed in the past century, despite warming temperatures in the region, according to new research led by University of Wyoming scientists.
A high-profile study made headlines in 2023 stating that the scientific and innovation system is producing less and less completely new knowledge. Researchers at the University of Basel are now refuting this claim, at least for patents: It is based on a measurement error.
From online abuse to threats of sexual violence, harassment of New Zealand's parliamentarians is on the rise, and becoming increasingly disturbing, University of Otago research shows.
A study by the University of Granada (UGR) shows that users understand advertisements better and with less effort when congruent emojis and messages are used. The findings also suggest a shift in the preferences of potential consumers towards more nature-based tourism.
It can be demoralizing for a person to work in a climate of repetitive skepticism and doubt about what they know, a new study shows.
Ceres, the largest asteroid in our solar system, harbors a dark secret: extremely young ice deposits in permanently shadowed craters near its poles. If that sounds vaguely familiar, it's because our moon and planet Mercury also have such polar ice deposits, which have been studied for decades.
Arctic and boreal latitudes are warming faster than any other region on Earth. In three new studies, Earth system scientists at the University of California, Irvine report how the ecosystems in these regions are changing.
In the field of organic chemistry, scientists are always looking out for new types of reactions to unlock synthesis routes for challenging compounds. Most of the progress that we have witnessed in pharmaceutics and agrochemicals over the past few decades can be traced back to the discovery of novel practical reaction pathways. Such pathways often involve the selective replacement of a functional group with another, the formation of aromatic rings, or the strategic cleaving of parts of a molecule. Читать дальше...
Providing hotel guests with messages about water use while they are taking a shower can reduce the length of time they spend showering by more than 25%, a new study has shown.
Climate change does not stop at grapevines. Too much sun means that the bouquet of German Riesling wines becomes dominated by a petrol note (some) customers do not appreciate. A research team from the Leibniz Institute for Food Systems Biology at the Technical University of Munich has identified the human odorant receptor responsible for the perception of this special aroma. Their paper is published in the Journal of Agricultural and Food Chemistry.
When designing repositories for high-level radioactive waste in deep geological layers, various factors must be carefully considered to ensure their long-term safety. Among other things, natural communities of microorganisms can influence the behavior of the waste, especially when it comes into contact with water. The microorganisms interact with released radionuclides and influence their mobility.
While it is the fastest growing sector of the wine-packaging market, canned wine faces a few hurdles. It's not considered as elegant as wine in a bottle, and it's not as popular as the formerly maligned "wine bag in a box." There is also the unfortunate fact—and there is no gentle way to put this—that canned wine occasionally smells like rotten eggs.
Over the past decade, metasurfaces deploying two-dimensional artificial nanostructures have emerged as a groundbreaking platform to manipulate light across various degrees of freedom. These metasurfaces exhibit significant potential in foundational scientific research and industrial applications.
The ongoing growth of a major Indian city has helped experts to create a new way of understanding how urban sprawl happens, providing potential to improve people's lives across the Global South through better urban planning.
Researchers who created "family trees" for nearly 10,000 fish have found that first-generation, wild-born descendants of hatchery-origin Chinook salmon in an Oregon river show improved fitness.
Researchers from IE Business School and Indian Institute of Management Shillong have published a new study that examines why certain consumers are averse to products using a novel technology and what strategies marketers can use to remedy this aversion.
