Two dangerous things together might make a medicine for one of the hardest cancers to treat. In a mouse model of pancreatic cancer, researchers have shown that bacteria can deliver deadly radiation to tumours — exploiting the immune suppression that normally makes the disease so intractable.

Reconfiguring the genetics of the food pathogen E. coli produces hydrocarbons indistinguishable from those burned in trucks. Welding bits and pieces from various microbes and the camphor tree into the genetic code of Escherichia coli has allowed scientists to convince the stomach bug to produce... Read More
New research at Washington University School of Medicine in St. Louis points to a common species of bacteria as an important contributor to bacterial vaginosis, a condition linked to preterm birth and increased risk of sexually transmitted diseases.
The condition affects one in every three wo... Read More
During my visit to Berkeley, CA to record TWiV #228, I met Deb Sklut, an artist who is inspired by the power of science. I recorded a brief conversation with Deb which you can view below. Her work can be found at SqueakySqueegeeArt.etsy.com. Read More
There’s no question that variation in size and shape has conferred selective advantages over the course of evolutionary time. One of the most obvious examples is the long neck and legs of the giraffe, which allow it to snatch foliage that is unreachable by vertically challenged competitors. The ... Read More
Salmonella is a major cause of human diarrhoeal infections and is frequently acquired from chickens, pigs and cattle, or their products. Around 94 million such infections occur in people worldwide each year, with approximately 50,000 cases in the UK per annum.
In a BBSRC-funded collaboration ... Read More
The cellular interior is criss-crossed by protein-based cables known as microtubules, each formed from 13 'protofilaments' composed of the protein tubulin. Microtubules are also associated with a host of other specialized proteins that help coordinate the transport of molecular cargoes and link ... Read More
The proportion of young women diagnosed with genital warts in Australia has seen a significant decline thanks to the HPV vaccine, suggests a new paper. In 2007, Australia became one of the first countries to implement a nationally funded quadrivalent human papillomarivus (HPV) vaccination progra... Read More
This video describes the role of microbes in the production side of the global food web. Microbes transform essentially inert gaseous nitrogen into active nitrogen compounds, which then go on to make amino acids and proteins. Read More
Despite the desperate need for new antibiotics to combat increasingly deadly resistant bacteria, the U.S. Food and Drug Administration (FDA) has approved only one new systemic antibiotic since the Infectious Diseases Society of America (IDSA) launched its 10 x ’20 Initiative in 2010 — and that d...

Efavirenz (tradenames: Sustiva, Stocrin) is an antiretroviral (ARV) drug commonly used to treat HIV. Its popularity as a medication, alone or more commonly in combination with other HIV medications (tradename: Atripla), is due to its superior effectiveness in suppressing replication of the virus...

It was a brew to rival any in “Macbeth.” The main ingredients were rat brain and a fearsome, carefully cultivated virus.
In his laboratory in Pearl River, N.Y., 20 miles north of Manhattan, Dr. Hilary Koprowski macerated the ingredients in an ordinary kitchen blender one January day in 1948. ... Read More
Clemson University researchers found that beer pong balls may carry dangerous bacteria, The Associated Press reported.
The balls collected by student researchers from parties over one weekend found salmonella, listeria, E. coli and staph, according to the AP. The study found a high level of b... Read More

In this blog entry, I discuss the perennial problem for educators: helping students find study strategies that help them reach their educational goals. I have found that student-generated study material is most helpful...and is sometimes quite artistic! Read More
When a new disease emerges, scientists and physicians hope something that’s already in the medicine cabinet can be used to treat it.
A new study suggests for the novel coronavirus, that may be the case.
Scientists from the U.S. National Institute of Allergy and Infectious Diseases are repo... Read More
The number of confirmed H7N9 bird flu cases in China increased by four to 91 on Friday. Jiangsu province reported one new case, and Zhejiang province reported three, the state-run Shanghai Daily reported today. The number of dead was unchanged at 17.
