A sample of Proteus mirabilis was inoculated on to a TSA plate by taking a sterile swab and placing a drop in the center of the plate. The plate was then incubated at 37 degrees for 8 hrs. Swarming motility can be seen as a clear halo and finger like projections coming from and around the grow... Read More
We’re in the midst of an extinction crisis, and it doesn’t involve Siberian tigers. Microbiologist Martin Blaser of New York University School of Medicine says that many species of germs are disappearing from our bodies—and that’s a problem. In his new book, Missing Microbes: How the Overuse of ... Read More
Bacteria can’t stick to a new type of nanoscale surface that could prove useful in food processing, medical, and shipping industries.
The technology uses an electrochemical process called anodization to create nanoscale pores that change the electrical charge and surface energy of a metal sur... Read More
I came across this paper and thought it sounded interesting for a discussion on TWiP:
Colonisation resistance in the sand fly gut: Leishmania protects Lutzomyia longipalpis from bacterial infection
Hi TWIM, TWIV and TWIP Argonauts,
Your three wonderful podcasts are the nutrient media for growing my scientific knowledge. I have been downloading them from ITunes for a couple of years, and although as a mere amateur I sometimes struggle to keep ... Read More
Researchers have created a synthetic DNA analog that can bind to and silence the gene responsible for NDM-1, a severe form of antibiotic resistance that can make ... Read More
Researchers have developed a high-tech method to rid the body of infections — even those caused by unknown pathogens. A device inspired by the spleen can quickly clean blood of everything from Escherichia coli to Ebola, researchers report on September 14 in Nature Medicine.
Blood infections c... Read More
Scientists from the University of Granada have successfully created magnetic bacteria that could be added to foodstuffs and could, after ingestion, help diagnose diseases of the digestive system like stomach cancer. These important findings constitute the first use of a food as a natural drug an... Read More
Chinese researchers have discovered what they say is the first ‘virological penicillin’ – MIR2911, a molecule found naturally in a Chinese herb called honeysuckle.
Honeysuckle (Lonicera japonica) is a well-known Chinese herb. In Traditional Chinese Medicine, it has been used to effectively tr... Read More
The TWiVocytes answer questions about Ebola virus, including mode of transmission, quarantine, incubation period, immunity, and much more.
For most of my life, if I’ve thought at all about the bacteria living on my skin, it has been while trying to scrub them away. But recently I spent four weeks rubbing them in. I was Subject 26 in testing a living bacterial skin tonic, developed by AOBiome, a biotech start-up in Cambridge, Mass. ... Read More
Simple stain done on an unknown bacteria, showing feathery rhizoid growth on TSA after a 48 hr incubation at 37 degree’s C, isolated from a floor swab. Single bacillus and diplobacillus can be seen though out. Read More
For MoMA PS1's Young Architect Program, David Benjamin and the architecture firm, The Living, utilized cutting-edge bio-design technologies to create a completely organic, compostable tower. The winning structure is composed of discarded cornstalks and mushroom material, and used zero energy in ... Read More
A flu vaccine that works against all flu viruses and provides protection for at least two decades is getting closer to reality, according to scientists at Mount Sinai Health System.
The organization’s vaccine would offer better and broader and longer-lasting protection against seasonal influe... Read More
Suzanne writes (re Aphids):
The best way to get rid of aphids in the garden (the ants in my yard love to herd them onto my okra) is a sharp stream of water from the hose. Aphids wash right off! They don't tend to come back right away, either.
A historical look back at the discovery of the AIDS virus. Margaret Heckler, president Reagan's Health and Human Services Secretary made the announcement to the world. “First, the probable cause of AIDS has been found: a variant of a known human cancer virus. Second, not only has the agent been ... Read More

The late computer scientist Randy Pausch wrote many inspirational things about life and academia during his struggle with pancreatic cancer. As we approach 2015, his words are helpful to me, and perhaps to others. About life, about academia, about helping others...and making our dreams come tr... Read More
Invasive species aren’t just species—they can also be pathogens. Such is the case with the West Nile virus. A mosquito-borne virus identified in the West Nile subregion in Uganda in 1937—hence the name—West Nile wasn’t much of a concern to people elsewhere until it broke out of Africa in 1999. T...

Antibiotic stewardship programs, which promote the appropriate use of antibiotics in hospitals and other healthcare centers, can not only lead to reduction in antibiotic use with no adverse effects but can also lead to significant savings, over $600,000 annually in the case of one New York Ho...
