A modified form of Green Fluorescent Protein integrated into an ammonium transporter provides a sensor that can be used to monitor transport activity in vivo.

Experiments on E. coli show that multiple mechanisms contribute to extreme resistance to ionizing radiation in bacteria, with mutations to three genes for DNA repair having a prominent role in one evolved population.

Increasing levels of atmospheric carbon dioxide reduce the mineral content but increase the levels of starch and sugars found in crop plants; which could exacerbate both obesity and malnutrition in some human populations.

The mitotic chromosome periphery is organised by the PP1 binding protein Ki-67 and contributes to nucleolar re-activation upon mitotic exit.

The Mcm2-7 motor unwinds DNA using an approach distinct from that of superfamily III helicases, and accesses multiple ring configurations and assembly states during the initiation of DNA replication.

Interactions in protein complexes can be predicted from evolutionary information from genomic sequences.

Post-phosphoryl modification of α-dystroglycan requires the glucuronyltransferase B4GAT1; this enzyme synthesizes the acceptor glycan that serves as a primer for the glycosyltransferase LARGE to synthesize the laminin-binding glycan.

Mapping microbial landscapes in indoor environments can predict how contaminants and spoilage resistance genes propagate within food-production environments, yielding novel insight for controlling spoilage.

A new hominin species found in a South African cave is part of one of the most unusual hominin fossil assemblages on record.
