Alkaline lysis was first described by Birnboim and Doly in 1979 (Nucleic Acids Res. 7, 1513-1523) and has, with a few modifications, been the preferred method for plasmid DNA extraction from bacteria ever since. The easiest way to describe how alkaline lysis works is to go through the procedure ... Read More

The Genome Sequencing Centers for Infectious Diseases (GSCID), funded by the National Institute of Allergy and Infectious Diseases (NIAID), are accepting applications for sequencing and genotyping projects. The three NIAID-sponsored Genome Sequencing Centers for Infectious Diseases are accepting... Read More
A small rectangular window on the front of the fermenter shows bubbling liquid inside. If it is clear, then that means it is only solution. If it is foggy, then bacteria have been added. Today, the liquid looks milky grey. It fizzes and froths as the correct amount of air and methane is added, ... Read More
A popular topic at the World Vaccines Congress was cell-based alternatives to egg-based technologies, which was called the next frontier by Dr. Richard Schwartz of NIAID.
In recent years, a number of research projects have revolved around producing vaccines in animals and plants. Arizona Stat... Read More

LIQUID asphalt is not a likely home, but hardy microbes have been found thriving in a natural lake made of the stuff. The discovery hints that alien life could exist in similar places.
Microbes are known to exist in tar pits, but it was not known if natural asphalt pools, with their more toxi... Read More
A genome is a complex system of genes and factors that regulate them. A European research team has clarified how such dynamic systems work, leading to a new way to predict genetic regulators.
As an organism develops and interacts with its environment, suites of genes are constantly being turn... Read More
Six years after the insect killer DDT was globally outlawed on grounds of environmental damage, two researchers say there are new reasons for doubting the chemical is harmful and are urging its use against malaria.
In a book launched on Wednesday, Donald Roberts, professor of tropical medicin... Read More
Natural compounds in cranberries are linked to the prevention of urinary tract infections (UTIs) but inconsistencies in methods currently used commercially to measure levels can result in the over- or under-estimation of potency levels, leaving product manufacturers and consumers without good da...

The University of Chicago’s Institute for Genomics and Systems Biology will partner with the Field Museum to study the evolution of species-switching parasites and pathogens that cause diseases such as bird flu, malaria, and AIDS.
The partnership, called the Emerging Pathogens Project, will i... Read More
Some bacteria take over cells by interfering with an important process called SUMOylation, which helps cells respond to stress. The bacteria release toxins that reprogram proteins inside cells, which prevents the cells from fighting their invaders, HHMI international research scholar Pascale Co... Read More
In this show, I report on four exciting stories: bacteria for digesting sushi; a giant virus that replicates itself, with help; microbes living in Mars-like lakes; and using viruses to generate hydrogen.

In the beginning there were Ida and Luca. The initial Darwinian ancestor - Ida - and the last universal common ancestor - Luca - assembled themselves from the spare parts sloshing around on the early Earth. Once all the ingredients were in place, it looks like life was all but inevitable.

An Agricultural Research Service (ARS ) scientist may have found a way to cut the amount of ammonia produced by cattle. To do it, he's using a key ingredient of the brewer's art: hops.
Cattle, deer, sheep, goats and other ruminant animals depend on a slew of naturally occurring bacteria to ai... Read More
