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 ...
New methods to study 'genetic invasion' detect the escape of crop genomes into the wild
Apr 05, 2016
Agricultural fields create a patchwork landscape that increases the potential for domesticated crop DNA to flood wild plant gene pools. This allelic introgression can cause significant evolutionary change in wild plant populations, ...
Designing gene therapy
Mar 31, 2016
Scientists at EMBL have increased the efficiency of a genome-engineering tool called Sleeping Beauty, which is showing promise in clinical trials of therapies for leukaemia and lymphoma. In a study published today in Nature ...
