Thermophiles, humans share ancient machinery used in cell division Biologists from Indiana University and Montana State University have discovered a striking connection between viruses such as HIV and Ebola and viruses that infect organisms called archaea that grow in volcanic hot springs. Despite the huge difference in environments and a 2 billion year evolutionary time span between archaea and humans, the viruses hijack the same set of proteins to break out of infected cells. In...

Microbes Found Speciating In Russian Hot Spring

[ Watch the Video ] It was Darwin who, upon studying evolving creatures, wondered how species diverge if they are living together. “That question really hasn´t been answered very well, even in the macro-organisms that we´ve studied for hundreds of years,” University of Illinois microbiology professor Rachel Whitaker ponders. Despite still being in close proximity to one another in an acidic, boiling habitat of a hot spring in Kamchatka, Russia, two groups of...

The June cover of the Journal of Virology features a photograph of the unusual effects on a cell infected by a virus. Montana State University researchers were the first to view the virus, which they collected from a boiling, acidic spring in Yellowstone. The article linked with the cover photograph describes the researchers' findings about the life cycle of the virus Sulfolobus turreted icosahedral virus (STIV). No one has seen STIV replicate within a host cell prior to the work done by MSU...

U.S. scientists say they've discovered populations of the microbe Sulfolobus islandicus that can live in boiling acid are more diverse than thought. University of Illinois researchers in Champaign said they found the diversity of S. islandicus is driven largely by geographic isolation and that finding demonstrates, for the first time, that geography trumps other factors that influence the makeup of genes in organism hosts. The researchers, led by Professor Rachel Whitaker, compared three...

Sulfolobus islandicus, a microbe that can live in boiling acid, is offering up its secrets to researchers hardy enough to capture it from the volcanic hot springs where it thrives. In a new study, researchers report that populations of S. islandicus are more diverse than previously thought, and that their diversity is driven largely by geographic isolation. The findings open a new window on microbial evolution, demonstrating for the first time that geography can trump other factors that...

Scientists are using designs in nature from extreme environments to overcome the challenges of producing materials on the nanometer scale. A team from the UK's John Innes Centre, the Scripps Research Institute in California and the Institut Pasteur in Paris have identified a stable, modifiable virus that could be used as a nanobuilding block. Viral nanoparticles (VNPs) are ideally sized, can be produced in large quantities, and are very stable and robust. They can self-assemble with very high...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
