Here's an Ebola puzzle for you: If the virus isn't airborne, why do doctors and nurses need to wear full protective suits, with face masks, while treating patients?
After we dug through studies and talked to scientists, the answer slowly emerged.
Ebola does spread through the air. But not ... Read More
It is a fascinating quirk of nature: Simple bacteria have an immune system with a memory, which allows them to destroy invading viruses they have encountered in the past.
The phenomenon is more than just a scientific curiosity. In just two years, scientists have discovered how to repurpose th... Read More
Have you thanked a vulture today? It turns out that they're getting rid of an awful lot of dangerous bacteria for us. According to new research published Tuesday in Nature Communications, the vulture has a gut designed to kill off the bacteria that thrive on the carrion they crave. When they cho... 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
A team of scientists has revealed how certain harmful bacteria drill into our cells to kill them. Their study shows how bacterial ‘nanodrills’ assemble themselves on the outer surfaces of our cells, and includes the first movie of how they then punch holes in the cells’ outer membranes. The rese... Read More
Plastic is well-known for sticking around in the environment for years without breaking down, contributing significantly to litter and landfills. But scientists have now discovered that bacteria from the guts of a worm known to munch on food packaging can degrade polyethylene, the most common pl... Read More
The TWiVbolans discuss the finding that human noroviruses, major causes of gastroenteritis, can for the first time be propagated in B cell cultures, with the help of enteric bacteria.

Sea stars are lovely marine invertebrates with a round central body connected to multiple radiating legs (photo credit). In the past year millions of sea stars in the west coast waters of North America have melted into piles of slime and ossicles. Sea star associated densovirus might be the caus... Read More
When we talk about viruses, usually we focus on the suffering caused by Ebola, influenza and the like. But our bodies are home to trillions of viruses, and new research hints that some of them may actually be keeping us healthy.
“Viruses have gotten a bad rap,” said Ken Cadwell, an immunologi... Read More
Vincent travels to Albert Einstein College of Medicine where he speaks with Kartik, Ganjam, and Margaret about their work on Ebolavirus entry, a tumor suppressor that binds the HIV-1 integrase, and the entry of togaviruses and flaviviruses into cells.

Researchers at North Carolina State University have for the first time mapped human disease-causing pathogens, dividing the world into a number of regions where similar diseases occur.
The findings show that the world can be separated into seven regions for vectored human diseases – diseases ... Read More
Scientists have now explained the mysteriously sudden appearance of a disease that has decimated sea stars on the North American Pacific Coast.
In a paper published Monday, November 17, 2014 in the journal Proceedings of the National Academy of Sciences, Cornell University microbiologist Ian ... Read More
