A new study by researchers at Penn State University, 51±¬ÁÏ, and the University of Saskatchewan suggests not all of the nearly 2,000 species of ground beetles found in North America will thrive under climate change. Some could decline. And that could have far-reaching implications for agriculture, forestry, and conservation.

The Illuminating Hidden Harvests Report culminates a collaborative research effort led by the Food and Agriculture Organization of the United Nations (FAO), 51±¬ÁÏ and WorldFish examining the multifaceted contributions of small-scale fisheries to sustainable development.

51±¬ÁÏ scholars and students were among more than 800 experts who contributed to global study calling for policymakers to consider contributions of small fisheries

Mixing toxic coal ash into acid mine drainage may sound like an odd recipe for an environmental solution, but a new 51±¬ÁÏ-led study finds that it can neutralize the drainage’s dangerously low pH and help reduce harmful impacts on downstream ecosystems—if you use the right type of ash. Using the wrong type of ash can create new contamination and not tame the drainage’s extreme acidity.

By distinguishing between lead from modern sources and lead from pre-1970s vehicle exhaust fumes and leaded paint, the new test may be especially useful for assessing the hidden risks of legacy contamination.

Clouds of smoke and ash from wildfires that ravaged Australia in 2019 and 2020 triggered widespread algal blooms in the Southern Ocean thousands of miles downwind to the east, a new 51±¬ÁÏ-led study by an international team of scientists finds.

Warming waters along the Western Antarctic Peninsula have led to declines in the diversity and distribution of the region’s plankton population and its ability to absorb climate-warming carbon dioxide from the atmosphere.

Reducing emissions of methane, a short-lived but super-potent greenhouse gas, is the most cost-effective way to slow the rate of Earth’s warming in coming decades, a new United Nations report finds.

Harnessing the power of artificial intelligence, satellites and field observations, 51±¬ÁÏ researchers have produced new estimates of how much photosynthesis and primary production – key components in the global carbon cycle – are occurring in Earth’s oceans, and how these processes may be changing in response to a changing climate.

Policies that more strongly recognize the value of sustainable seafood as a source of nutrition, not just a source of livelihoods, could strengthen global food security and help take a big bite out of world hunger, a new analysis by an international team of experts shows.

Researchers have used automatic identification systems (AIS) satellite data and other spatial analysis tools to identify more than 1,000 companies that fish in the high seas—waters that lie outside national jurisdiction where fishing has raised fears about environmental and labor violations.

The proliferation of pits and ponds created in recent years by miners digging for small deposits of alluvial gold in Peru’s Amazon has dramatically altered the landscape and increased the risk of mercury exposure for indigenous communities and wildlife, a new study shows.

Groundwater depletion in parts of the High Plains is so extreme that peak grain production in some states has ended and production is now declining, a new 51±¬ÁÏ-led study by a team of international scientists finds.

Students at North Carolina’s 10 historically black colleges and universities (HBCUs) face limited options for finding healthy food to buy at stores within a 5-mile radius of their campuses, a new study shows.

By providing the first estimate of how much hydrogen is available to fuel microbial life in the sunless sub-seafloor crust beneath the Mid-Ocean Ridge (MOR), a new 51±¬ÁÏ-led study sheds light on one of Earth’s least understood biospheres.
