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.

Similarities in the way that nucleosomes are organized into chromatin in archaea and eukaryotes suggest that chromatin might have been involved in gene regulation before its role in DNA packaging evolved.

A sudden fall in the levels of the coenzyme NADPH within cells could have a central role in the process of aging.

The Notch signaling pathway has a central role in the formation of the circuit that controls egg-laying in the nematode worm C. elegans.

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.

Fluorescence resonance energy transfer has been used to explore the interactions between DNA polymerases, sliding clamps and clamp loaders as DNA is replicated in human cells.

Mutagenesis studies identified an androgen receptor mutation that converts enzalutamide-a drug recently approved for the treatment of advanced prostate cancer-into an androgen receptor agonist, and modeling studies informed the design of novel drugs that are effective against the mutant receptor.

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

Longevity in C. elegans is influenced not only by insulin/IGF-1 signalling, but also by CAMKII and calcineurin, acting on the same target, the transcription factor DAF-16.
