Scientists find the shocking truth about electric fish

New research by a team led by UW-Madison biochemistry Professor Michael Sussman shows that electric fish, including the electric eel, evolved their electric organ six times independently over the course of evolutionary history. Sussman's team identified the molecular levers and developmental pathways that all six lineages of electric fish worldwide have in common, resolving a longstanding mystery of what scientists call convergent evolution, a problem Darwin himself pondered.Writing June 27, 2014 in the journal Science, a team of researchers led by Michael Sussman of the University of Wisconsin-Madison, Harold Zakon of the University of Texas at Austin...

Controversial clues of 2 'Goldilocks planets' that might support life are proven false

Mysteries about controversial signals coming from a dwarf star considered to be a prime target in the search for extraterrestrial life now have been solved in research led by scientists at Penn State University. The scientists have proven, for the first time, that some of the signals, which were suspected to be coming from two planets orbiting the star at a distance where liquid water could potentially exist, actually are coming from events inside the star itself, not from so-called "Goldilocks planets" where conditions are just right for supporting life. The study is published by the journal <i>Science</i> in its early online <i>Science</i> Express edition on July 3, 2014, and also in a later print edition of the journal.
This image shows the location of the six candidate planets that were believed to orbit the red dwarf star Gliese as of 2010. Blue indicates candidate planets in the habitable zone where conditions might be able to support life, orange indicates detections in the too-hot region that is too close to the star, green indicates detections in the too-cold region farther away from the star.Mysteries about controversial signals coming from a dwarf star considered to be a prime target in the search for extraterrestrial life now have been solved in research led by scientists...
