Problems achieving high yield and purity DNA are exaggerated in environmental samples because of the added complexity of microorganism lysis and inhibitor removal. Quantifying the nucleic acids in these samples is the easy part. But if you don’t know what to look for, you can easily make mista... Read More
The humble plasmid. We now know it so well, but as little as 60 years ago the field of extra-chromosomal heredity was decidedly murky. Not only was it the subject of great debate, conflict and friction within the scientific community, it was even used as a politico-religious tool during the Cold... Read More

Researchers investigating UK samples have found no association between the controversial xenotropic murine leukaemia virus-related virus (XMRV) and chronic fatigue syndrome (CFS). Their study, published in BioMed Central's open access journal Retrovirology, calls into question a potential link d... Read More
Merry Youle from www.smallthingsconidered.us explores 5 questions about lysogeny, the life cycle that takes place when a bacteriophage infects certain types of bacteria. Read More
Micro-blogging via Twitter is being evaluated as a means for tracking infectious diseases. The 2009 outbreak of H1N1 provided them an opportunity for testing Twitter as an approach for tracking disease outbreaks. From the end of April, researchers at the University of Iowa began collecting Twitt... Read More
Egypt's most famous pharaoh, King Tutankhamun, was a frail boy who suffered from a cleft palate and club foot. He died of complications from a broken leg exacerbated by malaria and his parents were most likely brother and sister.
Two years of DNA testing and CT scans on Tut's 3,300-year-old m... Read More
Columbus can stink.
Visitors to Downtown can be greeted with an odiferous punch from time to time, but the city is starting a project to fix that problem -- especially because it is finishing a $44 million effort designed to draw people to the Scioto riverfront.
A $6 million project to har... Read More
Ridding tap water of bacteria with chemicals is a common practice in America, but one Biodesign Institute researcher is finding benefits to putting the bacteria back in.
The use of microbial agents to decontaminate tap water has long been the standard in Europe, but an American bias against b... Read More
A less than 30-second movie from the 1950s shows a white blood cell (neutrophil) pursuing the Staphylococcus aureus bacteria on blood film.
The 16-mm moving image was captured by late David Rogers, who at the time was a professor at Vanderbilt University and went on to co-chair the National C... Read More
