Breaking the aphid's code
For the first time, scientists have sequenced the entire genome of the pea aphid, a notorious horticultural and agricultural pest, revealing the extent of the genetic collaboration of the aphid host with its bacterial symbiont. Source:Breaking the aphid's code
Warming hurts some populations, benefit others
Researchers say that higher temperatures could significantly reduce yields of wheat, rice and maize – dietary staples for tens of millions of poor people who subsist on less than $1 a day. Source:Warming hurts some populations, benefit others
Genes, environment, or chance?
Biologists attribute variations among individual organisms to differences in genes or environment, or both. But a new study of nematode worms with identical genes, raised in identical environments, has revealed another factor: chance. Source:Genes, environment, or chance?
