Recent data show that human children (up to 8 years old) perform poorly when required to innovate tools. Our tool-rich culture may be more reliant on social learning and more limited by domain-general constraints such as ill-structured problem solving than otherwise thought.

An unusual increase in the number of Campylobacter concisus isolates found in stool cultures provoked an outbreak investigation at Bern University Hospital. No epidemiological links were found between the cases, and the Campylobacter isolates were clonally unrelated. A change in culture conditions to a hydrogen-rich atmosphere enhancing growth of C. concisus was deemed responsible for this pseu...

A draft genome of a new Thermofilum sp. strain was obtained from an enrichment culture metagenome. Like its relatives, Thermofilum sp. strain NZ13 is adapted to organic-rich thermal environments and has to depend on other organisms and the environment for some key amino acids, purines, and cofactors.

BACKGROUND A tannic acid-inducible and mycoviral-regulated laccase3 (lac3) from the chestnut blight fungus Cryphonectria parasitica has recently been identified, but further characterization was hampered because of the precipitation of protein products by tannic acid supplementation. The present study investigated the heterologous expression of the functional laccase3 using a yeast Saccharomyce...

The characteristic limited reproductive life-span of normal human fibroblasts in culture is due to a steadily decreasing fraction of cells able to proliferate in the standard rich growth media. We have observed that restricting the growth factor supply to old cells for variable lengths of time in culture increases the fraction of cells that can enter S-phase; although these cells do not go on t...
