Transgenic mice with high levels of FGF21 live for longer than wild-type mice and do so without reducing food intake.

Histones bound to lipid droplets inside cells offer protection against bacteria in flies, and possibly mice, thus suggesting a possible new innate immunity pathway.

A mathematical model based on enzyme kinetics shows how the relationships between life expectancy, survival rates for children and adults, and national income change over time.

A combination of cellular, biochemical, genetic and genomic techniques have revealed a new molecular player in the production of fat cells in mice, which could improve our understanding of obesity.

Simulations and experiments on systems containing two different populations of microorganisms show that interactions that benefit at least one of the populations can lead to communities with stable compositions, and that strong cooperation between two populations can lead to communities in which both populations are mixed together.

Sugar levels in leaves act as a signal for plants to switch from their juvenile to their adult form by regulating the expression of two genes.

The ability to share resources for the benefit of all members of a group may have driven ancient organisms to evolve from a unicellular to a multicellular state.

Ubiquitin ligase adaptors target the selective clearance of misfolded plasma membrane proteins.
