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 unique form of regulation has been observed in the unfolded protein response of S. pombe, along with a novel mechanism of post-transcriptional mRNA processing.
The development of colonies of cells in choanoflagellates, water-dwelling organisms that feed on bacteria, is triggered by the presence of very low concentrations of a lipid molecule produced by certain types of bacteria.
Genome-wide measurements on mouse liver cells show that transcription, and a particular key transcription factor, have a smaller than expected influence on the mouse circadian system.
The transcription machinery used to regulate gene expression and self-renewal in human embryonic stem cells is different from that found in other cells.
A combination of advanced optical imaging and cryogenic electron microscopy has been used to explore membrane fusion in a synthetic system and provide new insights into neurotransmitter release.
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.
