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 ...
CRISPR/Cas9 used to mimic mitotic recombination to help map out genes
May 06, 2016 report
(Phys.org)—A small team of researchers with the University of California has developed a way to use CRISPR/Cas9 to mimic mitotic recombination in yeast cells leading to a new way to map out genes and by doing so, determine ...
Cells check DNA segregation at the end of their division
May 05, 2016
The cells in our bodies are constantly dividing. From embryonic development to adult life, cell division is necessary for tissue growth and renewal. During division, cells must duplicate their genetic material (or DNA) and ...
Ensuring the integrity of our genetic material during reproduction
Apr 07, 2016
The genetic information we receive from our parents in the form of chromosomes are mosaics assembled from the two copies of chromosomes each parent has. How such cuts—or breaks—in our genetic material are repaired is ...
'Honeycomb' of nanotubes could boost genetic engineering
Apr 06, 2016
Researchers have developed a new and highly efficient method for gene transfer. The technique, which involves culturing and transfecting cells with genetic material on an array of carbon nanotubes, appears to overcome the ...
