Reducing waste is one way to help combat hunger around the world, but stricter control over food loss and waste does not lead to better environmental outcomes, according to researchers at the University of California, Irvine and the University of Colorado Boulder. In a paper published recently in Nature Food, the scientists stress that curbing food spoilage increases the amount of produce in markets, which leads to lower costs.
For more than 40 years, there has been an effort to reduce nutrient loads to improve water quality in the Chesapeake Bay. The Chesapeake Bay’s Scientific and Technical Advisory Committee released a report on its three-year investigation into this effort. The results suggest that significant adjustments are needed to the existing programs as well as public expectations to improve its health.
Can biosurfactants increase microbiological oil degradation in North Sea seawater?

Humanity has a long track record of making big changes with little forethought. From fossil fuels to AI, plastics to pesticides, we love innovating away our problems, only to find we’ve created different ones.
Today's catalysts for removing unburnt methane from natural-gas engine emissions are either inefficient at low, start-up temperatures or break down at higher operating temperatures. A new single-atom catalyst solves both these problems and removes 90% of the methane.
Hazy, hazardous conditions from climate change-driven Canadian wildfires have prompted researchers to examine the physicochemical and toxicological properties.
Fertilizer restrictions along Florida’s 156-mile-long Indian River Lagoon were intended to reduce nutrient inputs from urban and agricultural land uses. The hope was that water quality would improve by reducing the nitrogen load. While these restrictions were well-intended, a study finds fertilizer use is not the root cause of the lagoon’s environmental issues. It’s sewage. For decades, fertilizer use was implicated for about 71 percent of the lagoon’s environmental impairments. In fact, current estimates show 79 percent of nitrogen loading is from septic systems; 21 percent is from residential fertilizer use.
Approximately a third of all anthropogenic methane is emitted by ruminant livestock. These animals get nutrients through fermenting food in four-chambered stomachs found in cows, sheep, and goats.
Greeshma Gadikota, an associate professor of civil and environmental engineering in Cornell Engineering, will lead an effort to decarbonize the concrete industry by harnessing carbon dioxide-capture and mineralization technologies to produce low-carbon construction materials. The $4 million project, part of President Joe Biden’s Clean Energy Plan, will be funded by the U.S. Department of Energy.

A freight train carrying industrial chemicals derailed near East Palestine, Ohio, in February 2023. Researchers have been assessing the local air quality. Now, in ACS’ Environmental Science & Technology Letters, they report that some gases, including acrolein, reached levels that could be hazardous.
Steven Allison, Professor of Ecology and Evolutionary Biology and Earth System Science, is using EMSL capabilities to uncover mysteries from the Earth beneath our feet. Allison explains how his research could help us understand severe events, like wildfire patterns, and how they affect soil microbiomes.
A new analysis of fine particulate matter exposure led by researchers at Washington University in St. Louis illuminates ways to improve health in India, Pakistan, Bangladesh, Nepal, Bhutan, Sri Lanka and Myanmar
Argonne was honored with the first Green Fleet Award as the laboratory continues to purchase zero-emissions vehicles.
Biologists attempting to conserve and restore denuded environments are limited by their scant knowledge of what those environments looked like before the arrival of humans.
New research has found that the design of biodegradable fishing gear needs to improve if it is to help address the environmental and economic impacts of ‘ghost fishing’.
Researchers from Switzerland and China have studied the global trade in highly hazardous chemicals subject to a global treaty – the Rotterdam Convention. The results are sobering: Nearly half of the total trade volume of these chemicals crosses national borders illegally, calling for strong international and national action.
Unused solar, wind, and hydroelectric power in the U.S. could support the exponential growth of transactions involving non-fungible tokens (NFTs), Cornell Engineering researchers have found.
As carbon removal increasingly plays a major role in response to climate change, a new fellowship program at American University’s Institute for Carbon Removal Law and Policy aims to center justice and equity considerations in carbon removal policy.
The community of microbial predators influences the composition of the bacterial community in wastewater. This explains seasonal variations in the microbial community that affect the efficiency of water treatment.
Researchers at the Paul Scherrer Institute PSI and ETH Zurich have performed calculations to work out how air traffic could become climate-neutral by 2050.
New research into public attitudes towards alternative shipping fuels shows public backing for biofuel and hydrogen
Sulphuric acid is the world’s most used chemical. It is an important reagent used in many industries and it is used in the manufacture of everything from paper, pharmaceuticals and cosmetics to batteries, detergents and fertilisers.
Researchers have found that one method of reducing greenhouse gas emissions is available, affordable, and capable of being implemented right now.
The extensive study assessed the movements of 7,137 individual birds from 77 species of petrel, a group of wide-ranging migratory seabirds including the Northern Fulmar and European Storm-petrel, and the Critically Endangered Newell’s Shearwater.
