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.

Intramembrane proteases identify target proteins in a different way from other proteases.

Preventing premature interactions between microtubules and protein-based structures called kinetochores ensures that chromosomes are segregated by meiosis rather than mitosis in reproductive cells.

Experiments in mice have shown than an enzyme that repairs broken DNA inside the nucleus also has a central role in the innate immune system because it is able to detect foreign DNA outside the nucleus.

The first survey of the complete morphologies of nerve endings in the skin of mice has revealed enormous structural diversity.

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.

Exposing rats to acute stress increased the generation of new neurons in a subregion of the hippocampus, and improved the animals' performance in a memory task two weeks later.

Enzymes that remove amine groups from cytosine bases in DNA are likely involved in generating the clusters of mutations (kataegis) seen in breast cancer.

The circadian clock in the model plant organism Arabidopsis thaliana is best described as a highly connected network made up of clock-regulated activators and repressors of transcription, rather than two coupled, repressor-based feedback loops.

A compound that prevents stressors such as UV light and viral infection from downregulating protein synthesis inside cells improves memory performance in mice.
