Burping bacteria: Identifying Arctic microbes that produce greenhouse gases
As greenhouse gases bubble up across the rapidly thawing Arctic, Sandia National Laboratories researchers are trying to identify other trace gases from soil microbes that could shed some light on what is occurring biologically in melting permafrost i.....»»
New insights into exotic nuclei creation using Langevin equation model
Researchers have introduced a model based on the Langevin equation that offers new insights into the formation of exotic nuclei. This development could enhance the ability to produce rare isotopes that are valuable for various applications in science.....»»
How emissions from Brazilian Pantanal"s soda lakes contribute to climate change
Seasonal variations with alternating dry and rainy seasons and fluctuating levels of nutrients are factors that significantly influence greenhouse gas emissions from soda lakes in the Pantanal, considered less common than emissions from freshwater la.....»»
Study tracks traveling population wave in Canada lynx
A new study by researchers at the University of Alaska Fairbanks's Institute of Arctic Biology provides compelling evidence that Canada lynx populations in Interior Alaska experience a "traveling population wave" affecting their reproduction, movemen.....»»

Retracing walrus ivory trade of Viking Age reveals early interactions between Europeans and Indigenous North Americans
By examining ancient walrus DNA, an international research team led by Lund University in Sweden have retraced the walrus ivory trade routes of the Viking Age. They found that Norse Vikings and Arctic Indigenous peoples were probably meeting and trad.....»»
Hunting down giant viruses that attack tiny algae
They were said to come from outer space, and there were even claims that they were actually bacteria and that they undermined the very definition of viruses. Giant viruses, nicknamed "giruses," contain enormous quantities of genetic material—up to.....»»
Inland waters crucial for accurate climate assessments, research suggests
Inland waters release substantial amounts of greenhouse gases, but this is rarely included in climate assessments. New research from Umeå University shows that not accounting for carbon fluxes between land and water systems leads to incorrect assess.....»»
New synthesis strategy could speed up PFAS decontamination
Rice University engineers have developed an innovative way to make covalent organic frameworks (COFs), special materials that can be used to trap gases, filter water and speed up chemical reactions. COFs have the potential to address significant envi.....»»
AI bots now beat 100% of those traffic-image CAPTCHAs
I, for one, welcome our traffic light-identifying overlords. Enlarge / Examples of the kind of CAPTCHAs that image-recognition bots can now get past 100 percent of the time. (credit: Arxiv, Plesner et al.) Anyone who has.....»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
The unexpected role of magnetic microbes in deep-sea mining
Polymetallic nodules are potato-sized formations on the ocean floor that are rich in minerals such as nickel, cobalt, and manganese. Their concentration of rare, economically important minerals has made the nodules the focus of controversial deep-sea.....»»
Presence of bacteria in soil makes flowers more attractive to pollinators, study shows
Bacteria that live in soil and help roots fix nitrogen can boost certain plants' capacity to reproduce, according to an article published in the American Journal of Botany describing a study of this mechanism in Chamaecrista latistipula, a legume bel.....»»
Citizens" panels help young people with special needs, disabilities make their voices heard on life-affecting policies
A new study shows participating in a citizens' panel can help young people with special educational needs/disabilities to produce new policy ideas about school inclusion. The study is published in the journal Frontiers in Education......»»
Brazil must reinforce protection of forests to meet climate change mitigation goals, study warns
As it prepares to host the 30th Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC COP 30, the first COP to be held in the Amazon) in November 2025, Brazil is at a crucial moment. Its greenhouse gas emissio.....»»
Identifying the top hazardous polluters in the path of Tropical Storm Helene
Recent projections show that Tropical Storm Helene, the latest storm brewing in the Gulf of Mexico, is heading for Florida and tracking toward the state's panhandle. An interactive map developed by Rice University's Center for Coastal Futures and Ada.....»»
Sustainable metal-recycling method reduces cost and greenhouse gas emissions
A research team led by Rice University's James Tour has developed a method to recycle valuable metals from electronic waste more efficiently while significantly reducing the environmental impact typically associated with metal recycling......»»
Ice cores show pollution"s impact on Arctic atmosphere
A Dartmouth-led study on ice cores from Alaska and Greenland found that air pollution from the burning of fossil fuels reaches the remote Arctic in amounts large enough to alter its fundamental atmospheric chemistry. The findings illustrate the long.....»»
Arctic sea ice near historic low; Antarctic ice continues decline
Arctic sea ice retreated to near-historic lows in the Northern Hemisphere this summer, likely melting to its minimum extent for the year on Sept.11, 2024, according to researchers at NASA and the National Snow and Ice Data Center (NSIDC). The decline.....»»
Bacterial "flipping" allows genes to assume different forms
Imagine being one cartwheel away from changing your appearance. One flip, and your brunette locks are platinum blond. That's not too far from what happens in some prokaryotes, or single-cell organisms, such as bacteria, that undergo something called.....»»
Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics
In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of ele.....»»
