When viruses come into contact with host cells, they trigger the cells to engulf them, or fuse themselves to the cell membrane so they can release their DNA into the cell.
Once inside a host cell, viruses take over its machinery to reproduce. Viruses override the host cell’s normal functioni... Read More
Here's a nice demonstration video by Dr. Conor O'Bryne from the Dept. of Microbiology at National University of Ireland, Galway, showing how to perform a serial dilution on a liquid food sample (in this case raw unpasteurised milk). The raw milk sample is diluted down to 1/1000 in a sterile dil... Read More

The emerging field of synthetic biology will allow researchers to create biological systems that do not occur naturally as well as to re-engineer existing biological systems to perform novel and beneficial tasks. As the science and its applications develop, a com... Read More
Bacteria have been sexually promiscuous, swapping genes with gusto, for a very long time. More than 15% of E. coli's genome has arrived via horizontal gene transfer (HGT), with some 200 installments having turned up since it diverged from Salmonella 100 million years ago. And, as you are probabl... Read More
