When a single tree makes a difference

A new study from American University found that individual trees can help mitigate urban heat, particularly in evening hours. The research showed that neighborhoods with at least half of the area covered by canopy were 1.4 degrees Celsius cooler than those with few trees.

Ecosystem destruction endangers local soy agriculture in Brazil

New research reveals that destroying tropical ecosystems leads to reduced soybean income by an average of US$100 per hectare per year due to increased extreme heat. Conservation of the Amazon and Cerrado biomes can prevent this damage, estimated to cost the sector US$3.55 billion annually.

Transport in 2050: Safer, cleaner and cost efficient?

A Cornell University-led team projects that vehicle electrification, driverless cars, and ride sharing could prevent 5,500 premature deaths and save $58 billion annually in the US by 2050. The study also finds that vehicle electrification is the most important piece for carbon mitigations and health benefits.

The promise of inclusive sustainability

A new model of inclusive sustainability emphasizes researchers' life experiences as a source of unique perspectives on socioecological challenges. This approach seeks to address the limitations of traditional conservation methods and promote more effective solutions.

Genome editing for food: how do people react?

A study of online surveys from five countries reveals that genome editing is generally viewed as beneficial for crops but raises concerns about animal welfare. The research found four distinct groups: strong supporters, supporters, neutrals, and opponents, with 21% strongly supporting the technology.

Songbirds like it sweet!

Researchers found that songbirds can sense sweetness regardless of their primary diets, with the ability emerging early within the songbird radiation. The team identified the molecular basis of this ability and found that it has been conserved in nearly half of all birds living today.
