In the atmospheric environment, the pollutants emitted by human activities are oxidized to secondary pollutants and gradually removed from the atmosphere. Therefore, the understanding of atmospheric oxidation is of great significance for air pollution control.

A large number of historical spy-satellite photographs from the Cold War Era were declassified decades ago. This valuable remote sensing data has been utilized by scientists across a wide range of disciplines from archaeology to civil engineering. However, its use in ecology and conservation remains limited.

The search for life beyond Earth fascinates many and inspires big questions: Are we truly alone in the universe? Is our Earth unique? Is it possible that life beyond Earth may actually be far from little green aliens and much closer to the microbial life with which we share our planet?

As we strive towards a circular economy, the application of treated sewage sludge (biosolids) to land is an opportunity to enhance soil health and reduce the reliance on synthetic fertilizers.

An often-overlooked water plant that can double its biomass in two days, capture nitrogen from the air—making it a valuable green fertilizer—and be fed to poultry and livestock could serve as life-saving food for humans in the event of a catastrophe or disaster, a new study led by Penn State researchers suggests.

Women continue to face barriers in entrepreneurship, with only 17 percent of small and medium-sized businesses being owned by women in Canada.

Millions of dollars are being spent to add sand to Southern California beaches—but a new study suggests technology can give a better understanding of how sand moves, offering data decision-makers could use in planning how to fix the eroding coastline.

A new report from the Chesapeake Bay Foundation says efforts to restore oyster populations could have benefits beyond just survival of the species.

Since 1996, a deadly neurodegenerative disease of cervids (deer, elk, moose, caribou, reindeer) has been spreading across Canada.

It's an all too common situation—you're busy cooking or baking to a recipe when you open the cupboard and suddenly realize you are missing an ingredient.

From Duluth, Lake Superior is a colossal expanse of blue this week with no otherworldly ice shards smashed against the shore or colorful fish houses decorating stretches of white.

Australia's nickel industry has been granted access to billions of dollars in federal funding as well as relief from royalty payments after a collapse in the global price of nickel that threatens thousands of jobs.

Oxidative functionalization of hydrophobic compounds is an important research area from the perspective of effective utilization of natural resources and treatment and reuse of hazardous substances. However, a method that can facilitate such reactions has not been well established.

In a study published in npj Climate and Atmospheric Science, a joint research group from the Institute of Earth Environment of the Chinese Academy of Sciences, the Stockholm University, and the California State University found that while land recycled water vapor contributes more than 60% to precipitation in northern China, the precipitation δ18O (δ18Op) is primarily influenced by the relative contribution of oceanic moisture.

Photosynthetic bacteria (PSB), unlike plants, do not generate oxygen as a photosynthetic byproduct because they use hydrogen sulfide instead of water to convert solar energy into chemical energy (electrons). This process is orchestrated by a protein complex, the light-harvesting 1-reaction center (LH1-RC).

Using the European Southern Observatory's (ESO) Very Large Telescope (VLT), astronomers have characterized a bright quasar, finding it to be not only the brightest of its kind but also the most luminous object ever observed. Quasars are the bright cores of distant galaxies, and supermassive black holes power them.

The green anaconda has long been considered one of the Amazon's most formidable and mysterious animals. Our new research, published in Diversity, upends scientific understanding of this magnificent creature, revealing it is actually two genetically different species. The surprising finding opens a new chapter in conservation of this top jungle predator.

The reproduction of giant sea spiders in Antarctica has been largely unknown to researchers for more than 140 years, until now. University of Hawaiʻi at Mānoa scientists traveled to the remote continent and saw first-hand the behaviors of these mysterious creatures, and their findings could have wider implications for marine life and ocean ecosystems in Antarctica and around the world. The researchers findings were published in Ecology.

A research group led by Prof. Wan Yinhua from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences has developed a coral-tentacle-inspired antifouling membrane spacer through the sequential growth of functional polymer brushes on the spacer surface. The study was published in AIChE Journal.

Ochroma pyramidale, commonly known as the balsa tree, is a large, fast-growing tree native to the Americas. The tree is known for its wide use in woodworking, due to its softness and its high strength compared to its low density.

The seven Colorado River states face a quickly approaching deadline to present a unified plan for how to manage the drying river that provides water for 40 million people across the West.

American humorist and writer Mark Twain is believed to have once said, "History doesn't repeat itself, but it often rhymes."

South Africa relies heavily on energy from coal-fired power stations, which emit large quantities of carbon. But making the transition to greater use of renewable energies, such as solar, is being hampered by a number of factors. Chief among them is corruption, which is affecting the quality of institutions.

Fresh U.S. intelligence circulating in Congress reportedly indicates that Russia is developing an anti-satellite weapon in space with a nuclear component.

Wheat, a globally important food crop, derives its yield from factors such as number of spikes per unit area, thousand-grain weight and grain yield per spike. Spike shape directly affects spikelet number, grain yield, and overall wheat productivity. Uncovering the key regulators of wheat spike development and investigating their molecular mechanisms holds great promise for precision breeding and molecular improvement of spike morphology.
