The Effects of Fracking on the Microbial Ecology of Groundwater

Hydraulic fracturing, or “fracking”, is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release natural gas inside. What effect does this process have on the microorganisms that naturally exist in the water in this process?

Antibiotic Compound from Wasp Venom

Antimicrobial peptides (AMPs) are part of the innate immune system that is widely distributed in nature, acting as a defense mechanism against invading microorganisms. AMPs have potent antimicrobial activity against a range of microorganisms including fungi, bacteria and viruses. In view of grow... Read More

Now We Know What Early Earth Smelled Like

Early earth had a distinctive aroma. And it wasn't very nice. That's what scientists have now determined, using advanced imaging techniques to examine fossils nearly 1.9 billion years old that were collected from rocks around Lake Superior, Canada.

Their work has revealed spherical and rod-sh... Read More

Fighting the Impact of Antibiotic-Resistant Bacteria

The resistance of bacteria to antibiotics and similar drugs—called antimicrobials—is considered a major public health threat by the Food and Drug Administration (FDA) and its counterparts around the world.

Antibiotics have transformed health care since they were introduced in the 1940s and ha... Read More

Marine Microbiology, Twitter Friends, and Shrunken Coffee Cups

In this blog entry, I discuss how marine microbiology is fascinating to students, as well as the topic leading me (via social media) to other marine microbiologists. One of those marine microbiologists made me a "shrunken coffee cup" (shrunken due to being carried below a kilometer of depth on ... Read More

France confirms 1st case of new SARS-related virus

A 65-year-old Frenchman is hospitalized after contracting France's first case of a deadly new respiratory virus related to SARS, and French health authorities said Wednesday they are trying to find anyone who might have been in contact with him to prevent it from spreading.

Not My Job: Kal Penn Takes A Quiz On The Microbiome (NPR's 'Wait, Wait, Don't Tell Me' segment)

Kal Penn has a pretty unusual resume: He has starred in Harold and Kumar, the most successful series of stoner movies made in the past decade; and has served in the White House as the Obama administration's liaison to youth. Now he's hosting a new show, The Big Brain Theory, on the Discovery Cha... Read More

Bacteria organize according to "rich-get-richer" principle

Bacteria on a surface wander around and often organize into highly resilient communities known as biofilms. It turns out that they organize in a rich-get-richer pattern similar to the distribution of wealth in the U.S. economy, according to a new study by researchers at University of California,...

Pictures Considered #4. Koch’s Development of Early InstaGram Positive Photography

Robert Koch is one of the key figures in early bacteriology, helping develop culture techniques (e.g. solid media), critical reasoning (e.g. Koch’s postulates), and disease etiology (e.g. cholera and tuberculosis). He also published the first photomicrographs of bacteria (Figure 1A) in his 1877 ... Read More

Update on H7N9: Should We Be Concerned?

The emergence of human infections with avian influenza viruses (H7N9 and H5N1) have raised concerns about the virus gaining the ability to spread person-to-person, potentially causing a deadly pandemic. So far the number of human cases has been limited but the mortality rates have been high. In ... Read More

Uncovering Dark Oxidants And The Dangerous Effect They Have On Life

Of all the things that could be hazardous to your health, would you believe breathing oxygen makes the list?

Our bodies produce toxic chemicals in our cells, called oxidants, which we fight naturally and with foods that contain antioxidants like blueberries and dark chocolate. All forms of li... Read More

Genes define the interaction of social amoeba and bacteria

Amoeba eat bacteria and other human pathogens, engulfing and destroying them – or being destroyed by them, but how these single-cell organisms distinguish and respond successfully to different bacterial classes has been largely unexplained.

In a report in the journal Current Biology, research... Read More

5 Amazing Benefits Of Gut Bacteria

The phrase "gut bacteria" might sound icky and repulsive, but modern science may have you soon thinking differently about the bugs that live in your intestinal system. Top researchers around the globe are exploring the bacteria that naturally reside in the bowels of both people and animals, and ... Read More

Potential flu pandemic lurks

In the summer of 1968, a new strain of influenza appeared in Hong Kong. This strain, known as H3N2, spread around the globe and eventually killed an estimated 1 million people.

A new study from MIT reveals that there are many strains of H3N2 circulating in birds and pigs that are genetically ... Read More
