New videos of morphing bacteria reveal that the strange, distinguishing features of so-called “electric bacteria” aren’t quite what they at first appeared to be.
For the past 10 years, scientists have been fascinated by a type of “electric bacteria” that shoots out long tendrils like electric... Read More
Paul Duprex joins the TWiV team to discuss the current moratorium on viral research to alter transmission, range and resistance, infectivity and immunity, and pathogenesis.
Dear Vincent & Dickson… and Daniel,
I always enjoy listening to TWIP here in Kona, Hawaii.
Our weather today is 79ºF and clear but we have just experienced a record 25-year overnight low of 54ºF,
Kansas State University diagnosticians are helping the cattle industry save millions of dollars each year by developing earlier and accurate detection of E. coli.

Evolution proceeds by selection of mutants that arise by error-prone duplication of nucleic acid genomes. It is believed that mutations that are selected in a gene are dependent on those that have preceded them, an effect known as epistasis. Analysis of a sequence of changes in the influenza vir...

Coccidiosis is a serious disease in new-born piglets. Caused by the parasite Cystoisospora suis, it exclusively infects pigs and often causes severe diarrhoea in suckling piglets. Parasitologists at the Vetmeduni Vienna have developed a new strategy for protecting the piglets: They infected sows... Read More
The TWiVers review the outcomes of two recent phase 3 clinical trials of a quadrivalent dengue virus vaccine in Asia and Latin America.
The latest outbreak of Ebola virus in west Africa is the worst ever—as of Monday, it had infected more than 1,200 people and claimed at least 672 victims since this spring. Guinea, Liberia and Sierra Leone all have confirmed cases. An official at Doctors Without Borders has declared the outbreak... Read More
Methicillin-resistant Staphylococcus aureus (MRSA), an antibiotic-resistant superbug, can cause life-threatening skin, bloodstream and surgical site infections or pneumonia. Researchers at the University of California, San Diego School of Medicine now report that cigarette smoke may make matters... Read More
Disruptions in the human circadian clock can throw off microbes in the gut, potentially boosting the risk of obesity, a new study suggests.
The results may help explain why shift workers and people who get jet lag by traveling frequently often pack on extra pounds.
"These surprising findin... 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
Thought you only had to deal with allergies these days? Well, maybe you've noticed some friends or work colleagues calling in sick lately—that may be because there's another flu strain making the rounds.
According to the Centers for Disease Control, influenza B is accounting for 55% of all vi... Read More
In some parts of the world, many small children become infected with severe diarrhea which often proves fatal. The condition is usually caused by strains of Escherichia coli (commonly known as E. coli) bacteria, and bacteria of the genus Yersinia. These bacteria attach themselves to the wall of ... Read More
The TWiVocytes answer questions about Ebola virus, including mode of transmission, quarantine, incubation period, immunity, and much more.
This is a paper from the Geomicrobiology lab at the Jackson School of Geosciences at the University of Texas at Austin. It was recently published in a special issue of Geomicrobiology Journal focused on geomicrobiology of subsurface microorganisms in cave environments.
In this study we attemp... Read More
Researchers from the University of Southern California and the Oak Crest Institute of Science have discovered the link between antibiotics and bacterial biofilm formation leading to chronic lung, sinus and ear infections. The study results, published in the current issue of PLOS ONE, illustrate ... Read More
Cyanobacteria could serve as a synthetic biology chassis that could be retooled for the production of biofuels, drugs or chemcials. So far, however, they have been held back by sluggish growth that makes it difficult to conduct the initial experiments needed to characterize their genetic and met... Read More
It's not a secret that the microbes living in our guts play a huge role in our well-being, or that, at least in the United States, we're doing a good job of killing them off.
But now new research finds that apes -- our closest relative -- have much more varied gut flora than humans do, and es... Read More
