Santa Fe Institute researchers look for life's lower limits



Santa Fe NM (SPX) Feb 07, 2017
When energy and nutrients abound, a bacterium will repair itself while synthesizing new parts to create a twin and then split, all as quickly as conditions allow. But if resources shrink, so does growth rate. The cell responds by shunting its dwindling supplies from replication to repair, shutting down processes until it's running a skeleton crew to survive. Below a crucial level, it's all over. Investigating the lower bound of energy required for life helps us understand ecological constraints on ... read more

Baltic hunter-gatherers began farming without influence of migration
New research indicates that Baltic hunter-gatherers were not swamped by migrations of early agriculturalists from the Middle East, as was the case for the rest of central and western Europe. Instead, these people probably acquired knowledge of farming and ceramics by sharing cultures and ideas - rather than genes - with outside communities. Scientists extracted ancient DNA from a number of ... more
