Flatburn is an open-source, mobile pollution detector intended to let people measure air quality cheaply.
Review of world water resources
A recent review study provides an overview of the planet's freshwater supplies and strategies for sustainably managing them.
East Coast, US, landslide impacts from Puerto Rico to Vermont and in between
In the U.S., we may often think of landslides as primarily a West Coast problem, mostly plaguing the mountainous terrain of California, Oregon, and Washington. New research highlights the major impacts of landslides on the U.S. East Coast and what is being done to save lives and deal with the...
Mild fever helps clear infections faster, new study suggests
It may be better to let a mild fever run its course instead of automatically reaching for medication, new University of Alberta research suggests. Researchers found that untreated moderate fever helped fish clear their bodies of infection rapidly, controlled inflammation and repaired damaged tissue. Moderate fever is self-resolving, meaning that...
Where did Earth’s water come from? Not melted meteorites, according to scientists
A new study brings scientists one step closer to answering the question of where Earth's water came from.
Recovering tropical forests offset just one quarter of carbon emissions from new tropical deforestation and forest degradation
A pioneering global study has found deforestation and forests lost or damaged due to human and environmental change, such as fire and logging, are fast outstripping current rates of forest regrowth.
Neolithic ceramics reveal dairy processing from milk of multiple species
A new study has found evidence of cheesemaking, using milk from multiple animals in Late Neolithic Poland.
‘Glow-in-the-dark’ proteins could help diagnose viral diseases
Despite recent advancements, many highly sensitive diagnostic tests for viral diseases still require complicated techniques to prepare a sample or interpret a result, making them impractical for point-of-care settings or areas with few resources. But now, a team has developed a sensitive method that analyzes viral nucleic acids in as...
Propeller advance paves way for quiet, efficient electric aviation
Electrification is seen as having an important role to play in the fossil-free aviation of tomorrow. But electric aviation is battling a trade-off dilemma: the more energy-efficient an electric aircraft is, the noisier it gets. Now, researchers have developed a propeller design optimization method that paves the way for quiet,...
New study finds early warning signs prior to 2002 Antarctic ice shelf collapse
In 2002, an area of ice about the size of Rhode Island dramatically broke away from Antarctica as the Larsen B ice shelf collapsed. A new study of the conditions that led to the collapse may reveal warning signs to watch for future Antarctic ice shelf retreat, according to a...
