As climate change threatens global food supplies, countries will need to increase the efficiency of food production, bringing about short-term gains, such as decreased deforestation, but long-term risks, including future pandemics stemming from animal-borne diseases, finds a new analysis appearing in the journal Science Advances.

Infection with the pandemic virus, SARS-CoV-2, can reduce the number of bacterial species in a patient’s gut, with the lesser diversity creating space for dangerous microbes to thrive, a new study finds.

PFAS (per-and polyfluoroalkyl substances), a group of more than 4,700 fully synthetic compounds that are widely used in industrial and manufacturing processes and found in many consumer products, persist through wastewater treatment at levels that may impact the long-term feasibility of "beneficial reuse of treated wastewater," according to a study conducted by researchers at Penn State and recently published in the Agronomy Journal.

“Dicamba drift” — the movement of the herbicide dicamba off crops through the atmosphere — can result in unintentional damage to neighboring plants. 

The University of Toronto has been ranked second in the world and first in Canada in the inaugural QS World University Rankings: Sustainability, which assesses universities for their environmental and social impact.

The preheating emissions were compared to calculated emissions from driving to determine the driving distance corresponding to the preheating emissions under current emissions standards.

Higher exposure to a certain type of traffic-related air pollution called particulate matter may be linked to an increased risk of dementia, according to a meta-analysis published in the October 26, 2022, online issue of Neurology, the medical journal of the American Academy of Neurology.

Population aging and economic development setbacks may outpace the health benefits of less air pollution and slowed climate change, according to a Penn State-led researcher team examining air quality and the factors most likely to impact future premature deaths.

In an age of industrialized farming and complex supply chains, the true environmental pressures of our global food system are often obscure and difficult to assess.

Hazardous levels of benzene, a gas known to cause leukemia and other blood cancers, are leaking from gas stoves in California, a new study finds.
