Dr Justice Tambo, lead author of the study published in the journal Food Policy, surveyed 1,474 farm households in Rwanda and Zambia and found that although farmers who visit plant clinics show a higher probability of opting for pesticides for pest control, they do not use them intensively and are more likely to adopt safer and more sustainable alternatives.

A study in Science Advances assessed the contribution of pollinators to international market flows and showed that nature conservation worldwide is essential to sustain current food consumption patterns. This interdisciplinary research across the fields of economics, ecology and environmental sciences revealed that developed countries are particularly reliant on imported pollinator-dependent crops from less-developed countries, where cropland expansion is reducing pollinators' natural habitat. Global governance should address the linkages between biodiversity, crop production and food consumption.

A Rice University-led study determines the best method yet for finding signs of SARS-CoV-2, the virus that causes COVID-19, in municipal wastewater.

Electrical current and laser light combine at a gold nanogap to prompt a dramatic burst of light. The phenomenon could be useful for nanophotonic switches in computer chips and for advanced photocatalysts.

When it comes to recreational crabbing--one of the most iconic pastimes along Maryland's shores--the current estimate of 8% of "total male commercial harvest" runs just a little too low. Biologists, with local community support, found stronger evidence for the underestimate in the first tagging study to estimate recreational blue crab harvest statewide.
