Many parasites commandeer the bodies of their hosts in order to spread. Examples of this include horsehair worms that reach water by forcing their cricket hosts to drown themselves, and liver flukes that drive infected ants to climb blades of grass, where cows can eat the insects, and so the flu...

Programming living cells offers the prospect of harnessing sophisticated biological machinery for transformative applications in energy, agriculture, water remediation and medicine. Inspired by engineering, researchers in the emerging field of synthetic biology have designed a tool box of small ... Read More
Amoebae — a group of amorphous, single-celled organisms that live in the human body — can kill human cells by biting off chunks of intestinal cells until they die, a new study finds. This is the first time scientists have seen this method of cell killing, and the new findings could one day help ... Read More
A common ingredient in antibacterial soap can be found in some people's noses, and the presence of this ingredient could be promoting the colonization of Staph bacteria, according to a small new study in the journal mBio.
Researchers from the University of Michigan found triclosan in the nasa... Read More
Analytical Chemistry Researchers have created a spinning disk that can quickly tell--within 30 minutes--if food samples contain Salmonella. The most widely-used method to test for the pathogen involves growing out samples on petri dishes and can take days so this has potential to be much quicker... Read More
Scientists at The University of Texas at Austin have discovered that a protein produced by the influenza A virus helps it outwit one of our body's natural defense mechanisms. That makes the protein a potentially good target for antiviral drugs directed against the influenza A virus.
Better an... Read More
ANYONE who walks in the woods will be familiar with witches’ brooms (pictured). Many trees sport these bushy tumours, which have a variety of causes. An important one is a group of bacteria called phytoplasma that are, in turn, carried from plant to plant by sap-sucking insects such as leafhoppe... Read More
While it is true that Taenia saginata tends to be benign as helminthic infestations go in humans, the same cannot be said for Taenia solium.
In both cases, ingestion of (encysted) larvae leads to enteric infestation wi... Read More
There’s nothing like an outbreak of Ebola virus disease to bring a small, struggling African nation to international notice. One week we couldn’t place it on a map; the next week, after Ebola virus disease strikes, we know the body count and the name of the capital and whether its airport has cl... Read More
This is the microbes' world—we just live in it. Throughout the history of Earth, microbes have radically reshaped life on the planet, from creating the very air we breath to wiping out almost all life on Earth. Don't underestimate the power of tiny, tiny microbes populating the Earth trillions o... Read More
The world’s only twin astronauts will take center stage in an upcoming NASA experiment that will analyze whether or not identical siblings remain the same biologically if one travels to outer space while the other remains on Earth.
According to the US space agency, astronaut Scott Kelly will ... Read More
Resistance to an entire class of antibiotics – aminoglycosides -- has the potential to spread to many types of bacteria, according to new biochemistry research. A mobile gene called NpmA was discovered in E. coli bacteria several years ago. Global spread of NpmA and related antibiotic resistance... Read More
GUECKEDOU, Guinea, April 8 (Thomson Reuters Foundation) - H iccups, say doctors in this remote corner of Guinea, are the final tell-tale sign of infection by the Ebola virus that has killed more than 100 people since an outbreak began this year.
Then come profuse bleeding, circulatory shock a... Read More
There’s a hidden war going on for your fruit. The apple snatchers and orange thieves aren’t what you might think, though. Humans and other fruit-loving species are locked in an ongoing evolutionary battle against the microbes that also want to feast. Now, researchers believe they have found out ... Read More
Q. When you eat yogurt or take a probiotic supplement, why aren’t the probiotic bacteria killed by stomach acids?
A. The point of consuming a probiotic supplement in a food like yogurt, a powder or a capsule is to introduce beneficial bacteria in the gut, said Dr. Christine Frissora, a gastro... Read More
Effect of founder cell density on the spatial pattern formation in colony biofilms.
The colony biofilms were obtained by following the protocol described in van Gestel et al (2014) ISME Journal (doi: 10.1038/ismej.2014.52). Briefly, GFP and mKATE2 labeled Bacillus subtilis strain were mixed in ... Read More
