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

A 2-year field study has demonstrated that volatile compounds produced by plants when they are attacked by herbivores act as defenses by attracting predators to the herbivores and increasing the reproduction of the plants.

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 molecular dynamics simulations and X-ray diffraction data has been used to construct more realistic models of proteins and to provide new insights into their interactions with other proteins and biomolecules.

Mathematical modeling shows that local populations of the malaria parasite self-organize into a limited number of transient but distinct strains through competition for hosts in immunity space.

Academic review committees would benefit from more details about the contributions made by individual researchers to papers with multiple authors, and also from more information about other types of scholarly communication.

The HITS-CLIP sequencing method is used to demonstrate that cryptic exons can detect messenger RNA that contains nonsense mutations, and then cause this RNA to decay, which shows that these exons are involved in maintaining the electrical balance of neurons and, possibly, preventing epilepsy.

Changing the order in which presynaptic and postsynaptic cells are repeatedly activated can change what a mammalian visual cortex neuron communicates to downstream neurons.

By using immune cells called dendritic cells to deliver drugs, it is possible to target and kill specific members of another class of immune cell, known as T cells, and to prevent these cells from attacking the body's own tissues in cases of autoimmune disease.
