Why Wildfire Smoke Travels So Far And How Long It Will Last

As hundreds of wildfires burn in Canada, parts of the U.S. are seeing thick smog and record high air quality issues caused by smoke from the blazes. Swaths of Canada’s eastern provinces, Quebec and Ontario, began battling fires over a week ago. So far, more than 9 million acres of land have been burned and over 20,000 people have evacuated, Canadian officials said Wednesday. Smoke from...

Using pressure and steam to create shrimp with fewer allergens

With the start of summer, many people will be firing up their grills and roasting everything from hot dogs to steaks. Shrimp won't be on the menu for millions of Americans with seafood allergies, though a method reported in the Journal of Agricultural and Food Chemistry could change that. The researchers say that reverse-pressure sterilization can produce a less-allergenic shrimp product, that...

Comprehensive new report tackles food safety risks in the informal sector of developing countries

A report commissioned by the International Livestock Research Institute (ILRI) and the CGIAR Initiative on One Health highlights the urgent need for innovative strategies to address food safety risks in the informal sector of developing countries. The report "New Directions for Tackling Food Safety Risks in the Informal Sector of Developing Countries" sheds light on the dominant role of...

Improving the quality of recyclate films by additivation

The quality of recyclate materials of plastics significantly affects their application. With the exception of slightly damaged production waste, recycled plastics cannot be used in their original form. Usually, they are sorted, cleaned, and reprocessed to form usable granules.

Shrinking endoscopes with meta-optical fibers

Ultra-compact, agile endoscopes with a large field of view (FoV), long depth of field (DoF), and short rigid tip length are essential for developing minimally invasive operations and new experimental surgeries. As these fields develop, the requirement for miniaturization and increased precision become progressively demanding.

Despite major progress nationally, two mercury emissions hotspots remain

Missing from partisan political debates over regulations affecting the energy sector is the stunning success of the federal government's signature environmental laws. A prime example: the U.S. Environmental Protection Agency's rules aimed at reducing the harmful effects of hazardous air pollutant (HAP) emissions from fossil fuel-fired power plants known as the Mercury and Air Toxics Standards, or...

Intentional defects make for better reactions, researchers report

A defect is not always a bad thing. In fact, when it comes to improving the electrocatalysis process that produces clean-burning hydrogen gas, it may be a very good thing. Researchers based in China engineered an electrocatalyst—which speeds up a desired reaction—with both amorphous and crystalline architectures that contains defects in the atomic structure. The defects enable the...

Where have all the petrels gone? Long-term study shows 90% population decline

To understand the effects of environmental changes on seabird populations, long-term studies are essential but rare. Biologists from Germany, Poland and Argentina have compiled data on the population dynamics and breeding success of Wilson's storm petrels in Antarctica over four decades and have now analyzed them under the direction of Prof. Petra Quillfeldt, Institute of Animal Ecology and...

Researchers outline best practices for understanding life on the ocean's vast seafloor

Resource managers and policymakers need robust data about marine ecosystems for decision-making and setting sound policies. However, data about marine life can be challenging to collect, integrate, and analyze. Invertebrate animals are a key component of life on the seafloor, but their wide range of body sizes and diversity make it especially difficult to understand their abundance and...

Twenty years of Mars Express images help build mosaic of the red planet

The Mars Express orbiter, the European Space Agency's (ESA) first interplanetary mission, entered orbit around Mars on June 2nd, 2003. Since then, the probe has mapped the Martian surface using its High-Resolution Stereo Camera (HRSC), an instrument built by the German Aerospace Center (DLR) with commercial partners. In honor of the mission's 20th anniversary, a celebration occurred last Friday...

New study demonstrates wild sea otters could help generate millions of dollars for local communities

A new study led by researchers at the Monterey Bay Aquarium and Middlebury Institute of International Studies' Center for the Blue Economy finds that sea otters attract recreational visitors to Elkhorn Slough, generating more than $3 million in revenues to local communities annually. Published in the Journal of Coastal and Ocean Economics, the study assessed the economic value provided by...

Study shows where professionals want to migrate within the European Union

Eastern Europe is the region in the European Union that is least appealing to professionals as a place to settle. A study led by researchers from the Max Planck Institute for Demographic Research in Rostock that used data from the employment platform LinkedIn to gauge migration interest found that fewer professionals from countries in Northern, Southern, and Western Europe want to move east. But...

Airbus develops a system to extract oxygen and metal from lunar regolith

New technologies using material found in space are constantly popping up, sometimes from smaller companies and sometimes from larger ones. Back in 2020, one of the largest companies of them all announced a technology that could have significant implications for the future lunar exploration missions planned over the next ten years. The European aerospace giant Airbus developed the Regolith to...

Scientists use seaweed to create new material that can store heat for reuse

Researchers from the SPECIFIC Innovation and Knowledge Centre and COATED M2A program at Swansea University have collaborated with the University of Bath to make a groundbreaking advancement in thermal storage research, developing a new efficient material that is easily scalable and can be sized and shaped to fit multiple applications.
