Urban agriculture has the potential to decentralize food supplies, provide environmental benefits like wildlife habitat, and mitigate environmental footprints, but researchers have identified knowledge gaps regarding both the benefits and risks of urban agriculture and the social processes of growing more food in urban areas.
Unraveling the role of supersulfides in regulating mitochondrial function and longevity
Supersulfides, many of which are produced by cysteinyl-tRNA synthetase (CARS), are essential compounds across many different lifeforms. However, the precise physiological roles of CARS-produced supersulfide are unclear. Now, using a strategically engineered yeast mutant with a deficient CARS gene, researchers from Japan have shown that supersulfides control cell longevity by...
Pacific kelp forests are far older that we thought
Fossils of kelp along the Pacific Coast are rare. Until now, the oldest fossil dated from 14 million years ago, leading to the view that today's denizens of the kelp forest -- marine mammals, urchins, sea birds -- coevolved with kelp. A recent amateur discovery pushes back the origin of...
Husker Study Finds Aquifer Depletion Threatens Crop Yields
Three decades of data have informed a new Nebraska-led study that shows how the depletion of groundwater — the same that many farmers rely on for irrigation — can threaten food production amid drought and drier climes.
Filaments of Phytoplankton in Australia
When satellites passed over South Australia’s Bonney Coast in January 2024, they captured images showing splotches of blue and green swirling through surface waters.
UBC-Led Initiative Protects Salmon Against Toxic Road Runoffs
The roads, bridges and highways that crisscross B.C. take us where we want to go.
Capturing Greenhouse Gases With the Help of Light
Researchers at ETH Zurich are developing a new method to remove CO2 from the atmosphere.
Pain-Based Weather Forecasts Could Influence Actions
Study shows desire for new forecasts, potentially altered behavior when risk is high.
How Fruit Flies Smell CO2
CO2 is an important source of information for insects.
Study quantifies how aquifer depletion threatens crop yields
Three decades of data have informed a new Nebraska-led study that shows how the depletion of groundwater -- the same that many farmers rely on for irrigation -- can threaten food production amid drought and drier climes. The study found that, due in part to the challenges of extracting groundwater,...
