Breakthrough in beta-lactam synthesis using nickel catalysts      (via sciencedaily.com) 

Researchers have made a significant breakthrough in the field of asymmetric synthesis of beta-lactams, which are prominent in bioactive compounds. Their innovative approach employs nickel and hydrocarbon sources that are abundant on Earth to access value-added beta-lactam products. The employment of nickel-hydride catalysis and alkenyl dioxazolone derivatives gives rise to the selective formation of four-membered lactam products.

Biodiversity protects against invasions of non-native tree species      (via sciencedaily.com) 

Researchers combined human and ecological factors to analyze the global scale of non-native tree species invasions. Human activity in hotspots of global trade, such as maritime ports, is linked to an increased likelihood of non-native tree species invasions. However, a high diversity of native tree species can help to curb the intensity of such invasions.

Hundreds of Andean bird species at risk due to deforestation: New research shows how to protect them      (via sciencedaily.com)     Original source 

Birds native to the tropical Andes are threatened by increasing agricultural development in the region. A new study combines a meta-analysis of papers on birds across the Andes with five years of fieldwork in Peru, revealing that open farmlands result in up to a 60% decline in the number of species in an area. The study documents how specific species are affected and provides tailored guidance for conservationists trying to protect them.
