From science writer Suzan Mazur, at Oscillations, interviewing Bogdan Dragnea, who studies the physical structure of viruses via spectrosopy: Suzan Mazur: Do you consider viruses live organisms since viruses can recognize their targets, attach, and infect their hosts—most viruses using a tail spike and needle [see following Parent lab image]—and as you’ve noted, they can Read More…
Viruses
Viruses invent their own genes? Then what is left of Darwinism?
From ScienceDaily: In 2013, the discovery of two giant viruses unlike anything seen before blurred the line between the viral and cellular world. Pandoraviruses are as big as bacteria, and contain genomes that are more complex than those found in some eukaryotic organisms (1). Their strange amphora shape and enormous, atypical genome (2) led scientists Read More…
Panspermia (maybe life came from outer space) is back, in Progress in Biophysics and Molecular Biology
Abstract: We review the salient evidence consistent with or predicted by the Hoyle-Wickramasinghe (H-W) thesis of Cometary (Cosmic) Biology. Much of this physical and biological evidence is multifactorial. One particular focus are the recent studies which date the emergence of the complex retroviruses of vertebrate lines at or just before the Cambrian Explosion of ∼500 Ma. Read More…
