The study, led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation, and Aarhus University, found that young people diagnosed with ADHD or ASD in Denmark now more closely resemble the broader population than those who received the same diagnoses 10 years earlier.

Two newly identified snail species have expanded the known diversity of European land snails. The species, Cochlostoma komarnica and Cochlostoma dobrido , are described in a new study published in the open-access Biodiversity Data Journal . Neither species has an English common name yet. Both are small, with cone-shaped shells measuring about 6 mm in length, and they live on limestone rocks where they feed on algae and lichens.
