Oxidative damage to a cell's DNA is constant and destructive and a complex suite of enzymes have evolved to repair and maintain it. In an important new step in teasing out these complex processes, an enzyme component known as Zf-GRF, which is highly conserved in several enzymes and across species, has been shown to be a key molecular tools that binds and orients repair enzymes to DNA.
Detailed information on 958 distinct morphological types of jellyfish that inhabit the Atlantic and Pacific coasts of South America has been compiled by scientists. The study involved scientists from Argentina, Chile, Peru, Colombia and Uruguay.
Low-cost, off-grid solar energy could provide significant economic benefit to people living in some remote areas, but a new study suggests they generally lack the access to financial resources, commercial institutions and markets needed to bring solar electricity to their communities.
