A team of scientists from Kaunas University of Technology and Lithuanian Energy Institute proposed a method to convert lint-microfibers found in clothes dryers into energy. They not only constructed a pilot pyrolysis plant but also developed a mathematical model to calculate possible economic and environmental outcomes of the technology. Researchers estimate that by converting lint microfibers...
Albeit very small, with a carapace width of only 3 cm, the Atlantic mangrove fiddler crab Leptuca thayeri can be a great help to scientists seeking to understand more about the effects of global climate change. In a study published in the journal Estuarine, Coastal and Shelf Science, Brazilian researchers supported by São Paulo Research Foundation (FAPESP) show how the ocean warming and...
Those in love with the outdoors can spend their entire lives chasing that perfect campsite. New University of Montana research suggests what they are trying to find.
Researchers have developed a way to dynamically switch the surface of liquidmetal between reflective and scattering states. This technology could one day be used to create electrically controllable mirrors or illumination devices.
Methane is a strong greenhouse gas that plays a key role in Earth's climate. Anytime we use natural gas, whether we light up our kitchen stove or barbeque, we are using methane.
Solar flares jetting out from the sun and thunderstorms generated on Earth impact the planet's ionosphere in different ways, which have implications for the ability to conduct long range communications.
A new study found higher education students are more engaged and motivated when they are taught using playful pedagogy rather than the traditional lecture-based method. The study was conducted by University of Colorado Denver counseling researcher Lisa Forbes and was published in the Journal of Teaching and Learning.
An interdisciplinary group of researchers from across the globe has comprehensively examined the sources and health effects of air pollution—not just on a global scale, but also individually for more than 200 countries.
A funny thing happened on the way to discovering how zinc impacts kidney stones—two different theories emerged, each contradicting the other. One: Zinc stops the growth of the calcium oxalate crystals that make up the stones; and two: It alters the surfaces of crystals which encourages further growth. Now it can be told—both theories are correct as reported in the American Chemical Society...
The future of quantum computing may depend on the further development and understanding of semiconductor materials known as transition metal dichalcogenides (TMDCs). These atomically thin materials develop unique and useful electrical, mechanical, and optical properties when they are manipulated by pressure, light, or temperature.
The spin of the Milky Way's galactic bar, which is made up of billions of clustered stars, has slowed by about a quarter since its formation, according to a new study by researchers at University College London (UCL) and the University of Oxford.
Our ability to confront global crises, from pandemics to climate change, depends on how we interact and share information.
The concentration of potentially toxic metals is increasing in the population of the franciscana dolphin—a small cetacean, endemic to the Rio de la Plata and an endangered species— according to a study led by a team of the Faculty of Biology and the Biodiversity Research Institute (IRBio), published in the journal Science of the Total Environment.
Does evolution explain why we can't resist a salty chip? Researchers at NC State University found that differences between the elemental composition of foods and the elemental needs of animals can explain the development of pleasing tastes like salty, umami and sweet.
An international research team led by Professor Dr. Frank Schäbitz has published a climate reconstruction of the last 200,000 years for Ethiopia. This means that high-resolution data are now available for the period when early Homo sapiens, our ancestors, made their way from Africa to Europe and Asia. Schäbitz and his colleagues determined the dates using a drill core of lake sediments deposited...
Dr. Sebastian Hess and his team at the University of Cologne's Institute of Zoology have studied a very rare and puzzling tripartite symbiosis. This consortium consists of a ciliate as host and two types of endosymbionts: A green alga and a previously unknown purple bacterium. Through genetic analyses of the pink-green ciliate, the researchers discovered that the endosymbiotic bacterium belongs to...
A current challenge for sustainable aquaculture is how to increase the quantities of farmed fish while also reducing waste products that can lead to the accumulation of harmful fish sludge. New research aims to understand how this fish waste can be treated for use in aquaponics systems.
Coronavirus disruption to weddings has highlighted the complexity and antiquity of marriage law and reinforced the need for reform, a new study shows.
Early migrations of humans to the Americas from Siberia around 12,000 years ago have been traced using the bacteria they carried by an international team including scientists at the University of Warwick.
A study of woodland ecosystems that provide habitat for rare and endangered species along streams and rivers throughout California reveals that some of these ecologically important areas are inadvertently benefitting from water that humans are diverting for their own needs. Though it seems a short-term boon to these ecosystems, the artificial supply creates an unintended dependence on its bounty,...
Those who deactivated their Facebook profiles report a lower regard for other ethnic groups, and this effect was more prevalent among people living in more ethnically homogenous areas, shows a new study of users in Bosnia and Herzegovina (BiH). The findings run counter to a commonly held view that social media usage exacerbates societal polarization.
Following 2020's extreme fire season, high-elevation forests in the central Rocky Mountains now are burning more than at any point in the past 2,000 years, according to a new University of Montana study set to publish in the Proceedings of the National Academy of Sciences.
You can take a fish out of toxic water, but its epigenetic mutations will remain for at least two generations.
The types of land around us play an important role in how major storms will unfold—flood waters may travel differently over rural versus urban areas, for example. However, it's challenging to get an accurate picture of land types using only satellite image data because it is so difficult to interpret.
