A new essay published in PLoS ONE looks at macroecology and sustainability. Humans are constrained by the systems that operate within the planet earth's ecological framework. Ecology has always been a minor partner in human endeavours, but seems to be the crucial one for us now.

T-Rex came and went, then mammals ruled, all the while the single-celled archaeon persisted with its slow growth lifestyle. Distantly related to bacteria, archaea have the slowest growth rate known to date.

Volcanic super-eruptions, with the potential to wipe out huge populations, could take just hundreds of years to form rather than the 100,000 previously thought, say American geologists.

The ZZW hen is female to start with but develops male characteristics and produces no fertile gametes (eggs OR sperm). Except that is for the ZZW Kentish plover, noted in the study of sex determination in birds.

Earthquake prediction is an inexact science and the recent Italian earthquake has highlighted the danger of not taking adequate precautions. An Anglo-Russian satelite programme hopes to be able to use electromagnetic signals as a means of early warning.

Theropod dinosaurs ruled the earth then died out in the Cretaceous, leaving the little mammals to diversify. Many genomes are now examinable for signs of diversification in these species' past.

Mutual benefits of a relationship between an ant species and pitcher plant; mutualism. Only one of the 120 species of the Nepenthes genus has been found so far to use a single plant - ant species within its tissues to help out.

Oetzi the iceman should not have had any blood preserved for the length of time (5,300 years) he has been lying in the mountains. But, as ever with this persistent man, Oetzi has come up trumps.
