I am Bibha Dahal, Graduate Teaching Assistant from South dakota State University, Brookings, SD. I have attached the image of nitrogen fixing bacteria, with water drop like appearance, grown on Nitrogen Free Medium, incubated at 28 degree Celsius for 4 days at microaerophilic condition.
Thank ... Read More
Bacteria may not have brains, but they do have memories, at least when it comes to viruses that attack them. Many bacteria have a molecular immune system which allows these microbes to capture and retain pieces of viral DNA that they have encountered in the past, in order to recognize and destro...

Jason Roberts, a virologist at the Victorian Infectious Disease Reference Laboratory in Melbourne, Australia, creates three-dimensional simulations of viruses showing how the molecules that make up the capsid and genome might move in very short periods of time. I visited Jason in his laboratory ... Read More
Dear Vincent, Dickson and Daniel,
I like your idea of a TWIP coffee mug prize (or maybe a mug discount).
In this second case study you presented, the present symptoms are pretty vague, but his history is interesting. Also since with ... Read More
Close up image of the edge of an unknown fungal contaminant showing concentric rings of black spore formation (center of colony) and nonspore forming white hypae on the outer edge of the colony. Fungal contaminant was found on TSA after a month of refrigerated temperatures, presumably an air bo... Read More
Living deep underground ain't easy. In addition to hellish temperatures and pressures, there's not a lot to eat. Which is why oil reservoirs are the microbes’ cornucopia in this hidden realm.
Microbes feast on many oil reservoirs, but it has been unclear how the micro-organisms got to those ... Read More
It’s a firmly established fact straight from Biology 101: Traits such as eye color and height are passed from one generation to the next through the parents’ DNA.
But now, a new study in mice by researchers at Washington University School of Medicine in St. Louis has shown that the DNA of ba... Read More
Rob Knight is a pioneer in studying human microbes, the community of tiny single-cell organisms living inside our bodies that have a huge — and largely unexplored — role in our health. “The three pounds of microbes that you carry around with you might be more important than every single gene you...

More than 600 years after the bubonic plague wiped out about half of Europe, scientists still don’t fully understand how bacteria that cause the disease travel from the site of a fleabite to the lymph nodes, where the rampage truly begins.
Researchers who’ve been studying the bacteria say the... Read More
A trial of a GSK/NIH candidate Ebola vaccine at Oxford University suggests the vaccine has an acceptable safety profile and is able to generate an immune response.
Pictured here are blue colonies of Methicillin-resistant Staphylococcus aureus (MRSA) growing on Remel Spectra MRSA medium. Spectra media contains a chromogen that yields a blue color as a result of phosphatase activity. The phosphatase enzyme is present in many staphylococci, including Staphylo... Read More
By the dawn of the 19th century, tuberculosis had killed one in seven of all people that had ever lived. Doctors believed it was hereditary, but had begun to observe that fresh air and outdoor living could sometimes change the course of the illness. Physician and TB patient Edward Trudeau was co...

Henry Ford Hospital researchers say that breastfeeding and other factors influence a baby’s immune system development and susceptibility to allergies and asthma by what’s in their gut.
The striking findings from a series of studies further advance the so-called hygiene hypothesis theory that ... Read More
We’re in the midst of an outbreak of debate, people arguing the merits of vaccinations. Its symptoms include feverish rhetoric and noxious op-eds. In an attempt to stem the spread of unhealthy attitudes toward science and misinformation about vaccines, the Bill & Melinda Gates Foundation sponsor... Read More
