Smallest-reported artificial virus could help advance gene therapy
Sep 21, 2016
Gene therapy is a kind of experimental treatment that is designed to fix faulty genetic material and help a patient fight off or recover from a disease. Now scientists have engineered the smallest-reported virus-like shell ...
First accurate simulation of a virus invading a cell
Sep 12, 2016
For the first time, scientists know what happens to a virus' shape when it invades a host cell, thanks to an experiment by researchers at Penn State College of Medicine and University of Pittsburgh School of Medicine. Understanding ...
Researchers discover a gene that is essential for the DNA-replication process
Sep 07, 2016
Millions of human cells are constantly dividing to repair tissue damage and ensure continuity. This is one of the most complex cellular processes, and in order for it to be successful, cells must produce a copy of their genetic ...
Placenta in females, muscle mass in males: The dual heritage of a virus
Sep 02, 2016
It is known that genes inherited from ancient retroviruses are essential to the placenta in mammals, a finding to which scientists in the Laboratoire Physiologie et Pathologie Moleacuteculaires des Retrovirus Endogenes et ...
Newly discovered multicomponent virus is the first of its kind to infect animals
Aug 25, 2016
For the first time, a multicomponent virus—which contains different segments of genetic material in separate particles, rather than a single strand of genetic material—has been found that is capable of infecting animals, ...
Teasing out the microbiome of the Kansas prairie
Jul 29, 2016
The Kansas prairie seems like the very picture of beauty and simplicity, with undulating fields of corn and wheat stretching as far as the eye can see.
How a cold gets into cells
Jun 20, 2016
Viruses smuggle their genetic material into our cells. How this actually works is currently being investigated at TU Wien (Vienna) using a new combination of analysis methods.
Ocean 'dandruff' a new tool for marine biologists
Jun 06, 2016
Police officers solve crimes with it. Doctors use it to predict the risk of certain cancers. Dog lovers find out the breeds of their mutts with it.
Trial and error in viral evolution: The difference between fading out, pandemic
May 23, 2016
Viruses evolve quickly. A small tweak to the genetic makeup of a mostly mild strain of influenza can give rise to the next pandemic. An equally small change to the same strain in a different setting can fade it into obscurity. ...
How viruses infect bacteria: A tale of a tail
May 18, 2016
Bacteriophages are viruses that infect bacteria. Using state-of-the-art tools, EPFL scientists have described a million-atom "tail" that bacteriophages use to breach bacterial surfaces. The breakthrough has major implications ...
