"A bench-top genetic experiment demonstrates a big, quirky and still-hazily-understood evolutionary principle called pre-adaptation: how mutations accumulate that individually do nothing, but combine to produce radical adaptation."
"Ancient rocks are shedding new light on the timeline for life's emergence on Earth. The rocks contain carbon-based minerals that may be much younger than the rocks they inhabit, indicating that the carbon was mixed with the rock later than the rock's actual formation."
"Scientists have known for a while that if you put harmful bacteria into outer space, they tend to get even more harmful. Since that discovery, researchers have been itching to know if the zero gravity and radiation of space will have similar effects on beneficial bacteria."
"When they dive together, sperm whales make patterns of clicks to each other known as 'codas.' Recent findings suggest that not only do different codas mean different things, but that whales can also tell which member of their community is speaking based on the sound properties of the codas. Just as we can tell our friends apart by the sounds of their voices and the way they pronounce their words, different sperm whales make the same pattern of clicks, but with different accents."
