New results from the Lenski E. coli experiment

One of the most beautiful experiments in evolutionary biology is the one by Michigan State University’s Richard Lenski and his team, most recently Zachary Blount, who started out in 1988 with a single strain of E. Coli bacteria, separated it into twelve genetically identical lines, and then did experiments on them to see how each strand evolved. By now 55,000 generations have occurred, a crucial fact since in evolution it is the number of generations that is the appropriate measure of time, not years. [Read more…]

Scientists, journals, and science journalists behaving badly

Science journalism plays an extremely important role in translating the almost impenetrable jargon and style of journal articles into languagethat can be digested by the general public.

But in order to make their work appealing to the general public, scientists make often make passing claims in their papers that are not as well supported by their data but catch the eye of journalists who then give them undue weight. Seth Mnookin has pointed out recent examples where this practice has caused widespread public misunderstanding of the results of research. [Read more…]
