A team of scientists in the United Kingdom and the Netherlands are reporting disturbing evidence that soil microbes have become progressively more resistant to antibiotics over the last 60 years. Surprisingly, this trend continues despite more stringent rules on use of antibiotics in medicine an... Read More
The Norwegian dairy company TINE is now planning an in-depth study that will find out whether household bacteria can be used for their own sake.
When the Norwegian dairy company TINE makes cheese, it deliberately adds certain organisms to the raw milk. Others get there by chance and shape the... Read More

The human gut holds microbes containing millions of genes, say scientists.
In fact, there are more genes in the flora in the intestinal system than the rest of our bodies. So many that they are being dubbed our "second genome".
A study published in the journal Nature details the analysis o... Read More
The most comprehensive way to evaluate DNA concentration and purity is to use both UV spectrophotometeric measurements and agarose gel eletrophoresis. This quick reference guide gives an overview of the information that can be derived from both.
This article is a clear and concise guide to th... Read More
You are going to spend at least 4 years or more in graduate school, and around 3-5 years in a postdoc position. That’s a big chunk of your life, so apart from doing experiments, writing papers or your thesis and maybe doing some teaching, what else are you doing?
To paraphrase one of my favor... Read More
How’s this for irony – the U.S. Food and Drug Administration is warning consumers to stop using two brands of hand sanitizers because they contain … dangerous bacteria.
That’s right. “Bee-Shield Hand Sanitizer” and “MD Quality Hand Sanitizer” (both made with aloe vera) were found to have high... Read More

Welcome to Ms. Baker and her biology students extreme biology blog! This is perhaps one of the best high school student blogs I have ever seen.
In Extreme Biology, students post about "anything biology-related." Check out the post by Amy Ciardiello, a 9th grade violinist, who writes about "v... Read More
As climatologists weather the IPCC controversy, another storm is brewing, and this one is filled with not with bloggers but with beasts, bugs and bacteria. It is the potential plague of infectious diseases—threatened to be made worse, many scientists propose, by projected changes in the Earth's ... Read More
Understanding how plants defend themselves from bacterial infections may help researchers understand how people and other animals could be better protected from such pathogens.
That’s the idea behind a study to observe a specific bacteria that infects tomatoes but normally does not bother the... Read More

Currently, beachgoers are informed about water-quality conditions based on results from the previous day's sample. Scientists must collect samples in the field, then return to a lab to culture them for analysis — a process that takes a minimum of 24 hours.
Now, engineers from the UCLA Henry ... Read More

Idaho National Laboratory biologist Frank Roberto squats on a gravelly patch of ground in Yellowstone National Park. At his feet, scalding water churns in a mustard-yellow pool the size of a wheelbarrow. Roberto reaches in with a plastic vial and scoops up a half-cup.
“That’s a good sample,” ... Read More
Scientists in Manchester, UK have found a clean and green way of making tiny magnets for high tech gadgets—using natural bacteria that have been around for millions of years. The work by a team of geomicrobiologists from the Univ. of Manchester paves the way for nanometer-size magnets – used in ... Read More
Scientists in the US have developed a microdevice that investigates how bacteria communicate with each other to enhance their resistance to drugs.
Bacteria communicate in a process called quorum sensing, in which they secrete small signalling molecules called autoinducers. When bacteria pr... Read More
