  • Plants communicate at a molecular level - Biologists have discovered how tomato plants identify Cuscuta as a parasite. The plant has a protein in its cell walls that is identified as 'foreign' by a receptor in the tomato.
  • Trees bring benefits to society, regardless of their origin - Trees planted in urban spaces provide a multitude of ecosystem and social services. At the same time, trees can be a source of inconveniences. Scientists have analyzed trees found in the Geneva region, and systematically assessed the services and inconveniences they generate. They show that most tree species are non-native, and that trees provide roughly the same ecosystem services to Geneva's urban spaces regardless of their origin.
  • These two bird-sized dinosaurs evolved the ability to glide, but weren't great at it - Despite having bat-like wings, two small dinosaurs, Yi and Ambopteryx, struggled to fly, only managing to glide clumsily between the trees where they lived, researchers report. Unable to compete with other tree-dwelling dinosaurs and early birds, they went extinct after just a few million years. The findings support that dinosaurs evolved flight in several different ways before modern birds evolved.
