'Paleo Ale' Brewed From Yeast Found On A 40-Million-Year-Old Whale Fossil

A Virginia brewer soon plans to serve a beer made from yeast found hanging out on a 40-million-year-old whale fossil, the blog Symbiartic reports. Depending on your disposition, I imagine you're reacting in one of two ways right now, "Yecchh!" or "Cool!" The beer will be called Bone Dusters Pale... Read More

E.coli on MacConkey Agar (Mac)

Streak plate isolation of E. coli on MacConkey Agar grown for 24 hrs at 37 degrees. E. coli demonstrates strong lactose fermentation indicated by the bright pink halo, bile precipitant around the colonies, and pink colony growth. Read More

Conidiophores in Neurospora crassa

This is an 3D image of conidiophores of the filamentous fungus Neurospora crassa. Conidiophores are hyphae which differentiate to produce asexual structures named spores or conidia. The image taken using a confocal microscope shows conidiophores stained with a fluorophore which stains components... Read More

Dear Vincent,


To my great delight, I just discovered your podcasts twiv, twim and twip.


The first twip I heard, about Strongyloides stercoralis, although informative and interesting, seemed to have several inaccuracies. I w... Read More

Light zaps viruses: How photosensitization can stop viruses from infecting cells

A UCLA-led team of researchers has found evidence that photosensitizing a virus's membrane covering can inhibit its ability to enter cells and potentially lead to the development of stronger, cheaper medications to fight a host of tough viruses.

The UCLA AIDS Institute study, published in th... Read More

Using tobacco to thwart West Nile virus

An international research group led by Arizona State University professor Qiang "Shawn" Chen has developed a new generation of potentially safer and more cost-effective therapeutics against West Nile virus, and other pathogens. The therapeutics, known as monoclonal antibodies (MAbs) and their de... Read More

The Energizer Bacterium

Many bacteria have a trick for surviving a water shortage: They dry up like raisins and turn into spores, protecting their essential genetic code. But moisten a spore and it swells right up again.

Those capabilities give bacterial spores some interesting potential as an energy source, as scie... Read More

Should variola virus, the agent of smallpox, be destroyed?

Later this month (May 2014) the World Health Assembly will decide whether to destroy the remaining stocks of variola virus – the agent of smallpox – or to allow continued research on the virus at WHO-approved laboratories. We are interested in your opinion on this issue. Please follow the link t... Read More

Finally, Clothing Designed to Stop the Spread of Germs on Public Transit

Of all the public transit etiquette violations out there, the sneeze-and-touch at the height of cold and flu season is among the worst. Everyone who rides in a city has seen it: that sickly looking person across the train or bus who sneezes into a free hand then grabs the pole we all share. Rese... Read More

ASM GM 2014 - Where Pathogens Can Linger on Airplanes

Many air travelers are concerned about the risks of catching a disease from other passengers given the long time spent in crowded air cabins. New research shows disease-causing bacteria can linger on surfaces commonly found in airplane cabins for days, even up to a week. Participants discuss ... Read More

Antibiotic developed 50 years ago may be the key to fighting ‘superbugs’

Scientists at the University at Buffalo are turning to an old class of antibiotics to fight new superbugs resistant to modern medicine.

A $4.4 million grant from the National Institutes of Health will allow UB researchers to develop new dosing regimens for polymyxin antibiotics.

Developed ... Read More

Algae able to switch quantum coherence on and off

A UNSW-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis.

The function in the algae of this quantum effect, known as coherence, remains a mystery, but it is thoug... Read More

I had the bacteria in my gut analysed. And this may be the future of medicine

Andrew Anthony sent his stool off to have its bacteria sequenced. In the future, such techniques could help assess our susceptibility to conditions from diabetes, Parkinson's and Alzheimer's to autism, depression and cancer.
