April Flowers for redOrbit.com - Your Universe Online Michigan State University researchers and colleagues from the University of Texas and the University of Calgary have documented the step-by-step process in which organisms evolve new functions. The study results are revealed through an in-depth, genomics-based analysis that decodes how E. coli bacteria figured out how to supplement a traditional diet of glucose with an extra course of citrate. “It´s pretty nifty to see...

Queen Of Spades Key To New Evolutionary Hypothesis

Microscopic ocean plankton mimic card also known as the Black Queen Sleight of hand is a trait that belongs mainly to humans. Or so scientists thought. Studies of common, microscopic ocean plankton named Prochlorococcus show that humans aren't the only ones who can play a mean game of cards. Their method lurks in the Black Queen Hypothesis, as it's called, after the Queen of Spades in the card game Hearts. Scientists Jeffrey Morris and Richard Lenski of Michigan State...

In the current issue of Science, researchers at Michigan State University demonstrate how a new virus evolves, which sheds light on how easy it can be for diseases to gain dangerous mutations. The scientists showed for the first time how the virus called “Lambda” evolved to find a new way to attack host cells, an innovation that took four mutations to accomplish. This virus infects bacteria, in particular the common E. coli bacterium. Lambda isn´t dangerous to humans, but...

Organisms focusing on long-term mutations survive while others focusing on short-term fitness gains go extinct In some cases, less fit organisms may out-survive their in-shape counterparts, according to a study reported in the March 18 issue of Science. The finding surprised researchers who assumed less fit organisms would be the eventual losers in evolution's fight for survival. Microbial Ecology professor Richard Lenski of Michigan State University conducted the study with funding from the...

When it comes to survival of the fittest, it's sometimes better to be an adaptable tortoise than a fitness-oriented hare, a Michigan State University evolutionary biologist says. In this week's Science magazine, Richard Lenski, MSU Hannah Distinguished Professor of Microbiology and Molecular Genetics, and colleagues show that more adaptable bacteria oriented toward long-term improvement prevailed over competitors that held a short-term advantage. The discovery that the less-fit organisms...

40,000 generations and counting at Michigan State University A 21-year Michigan State University experiment that distills the essence of evolution in laboratory flasks not only demonstrates natural selection at work, but could lead to biotechnology and medical research advances, researchers said. Charles Darwin's seminal Origin of Species first laid out the case for evolution exactly 150 years ago. Now, MSU professor Richard Lenski and colleagues document the process in their analysis of...

pungle
  • To take pains; labor assiduously with little progress.
This word comes from the Spanish 'pongale,' put it.
