Common household products containing nanoparticles -- grains of engineered material so miniscule they are invisible to the eye -- could be contributing to a new form of indoor air pollution, according to a new study.
Astronomers share climate-friendly meeting solutions
Carbon emissions associated with air travel to professional conferences make up a sizable fraction of the emissions produced by researchers in academia.
Scientists show ancient village adapted to drought, rising seas
Researchers have unveiled evidence for ancient human resilience to climate change in the Eastern Mediterranean.
New and improved way to grow the cells that give rise to the kidney’s filtration system
Scientists report significant progress in cultivating nephron progenitor cells (NPCs), the cells destined to form the kidney's filtration system, the nephrons. NPCs hold immense promise for understanding kidney development, modeling diseases, and discovering new treatments. The team improved the chemical cocktail for generating and growing NPCs in the laboratory, enabling...
Big data reveals true climate impact of worldwide air travel
A new study that looked at nearly 40 million flights in 2019 calculated the greenhouse gas emissions from air travel for essentially every country on the planet. At 911 million tons, the total emissions from aviation are 50 per cent higher than the 604 million tons reported to the United...
Methane emissions from landfill could be turned into sustainable jet fuel in plasma chemistry leap
Researchers have developed a chemical process using plasma that could create sustainable jet fuel from methane gas emitted from landfills, potentially creating a low-carbon aviation industry.
Researchers parse oddity of distantly related bats in Solomon Islands that appear identical
A study of body size in leaf-nosed bats of the Solomon Islands has revealed surprising genetic diversity among nearly indistinguishable species on different islands.
Trotting robots reveal emergence of animal gait transitions
A four-legged robot trained with machine learning has learned to avoid falls by spontaneously switching between walking, trotting, and pronking -- a milestone for roboticists as well as biologists interested in animal locomotion.
New technology makes 3D microscopes easier to use, less expensive to manufacture
3D microscopes are used in applications from the life sciences to semiconductor manufacturing. Now engineers are developing patented and patent-pending innovations making them work faster to capture even more 3D images and less expensive to manufacture.
A virus could help save billions of gallons of wastewater produced by fracking
An estimated 168 billion gallons of wastewater -- or produced water -- is generated annually by the Permian Basin fracking industry, according to a 2022 report. The major waste stream has proved both difficult and costly to treat because of the chemical complexity of the water.
