A healthy and balanced diet, as well as probiotics, have been known to be helpful in preserving gastrointestinal health for quite a long time. But it is only recently that the underlying mechanisms have become somewhat clearer. A rapidly increasing body of knowledge promises to further clarify t... Read More
Antibiotics are valuable, potentially life-saving tools that have significantly reduced human morbidity and mortality. Unfortunately, antibiotics may also have unintended consequences from their off-target effects that may increase the risk of many long-term conditions. Recent epidemiologic stud... Read More
The gut microbiota contains a vast number of microorganisms from all three domains of life, including bacteria, archaea and fungi, as well as viruses. These interact in a complex way to contribute towards both health and the development of disease — interactions that are only now being elucidate... Read More
In a new study, Harvard scientists show that the bacterium Rhodopseudomonas palustris can use natural conductivity to pull electrons from minerals located deep in soil and sediment while remaining at the surface.

Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is left for longer periods of time, according to the findings of research carried out at Aston University’s School of Life and Health Sciences. The findings suggest there may be some scientific b... Read More
Every year, Americans send millions of tons of food to the landfill. What if you could use all of those pizza crusts and rotten vegetables to heat your home? That's already happening in one unlikely laboratory: the Newtown Creek Wastewater Treatment Plant in Brooklyn.

Microbiologists have known for some time that different diets produce different gut flora, but new research indicates that the changes take hold with startling quickness. Bacterial populations shift measurably in the first few days following a big shift in what we eat, according to a recent stud... Read More
It all started with a tiny chunk of dirt. The sample of 30,000-year-old permafrost, a frozen layer of soil from the Siberian tundra, weighed just a fraction of an ounce. But, as TIME reported on Tuesday, that scrap was carrying within it a surprise worthy of a pulp comic book: a gargantuan virus... Read More
When a mysterious disease fells people — as happened in California recently, with as many as 20 children experiencing unexplained paralysis — teams of physicians and epidemiologists quickly mobilize. Perhaps you saw the movie “Contagion”? The idea is to find the culprit before it spreads but als... Read More
A new study has revealed that bacteria use a form of communication similar to human language, but employing chemical signals instead of words. This language enables bacteria to thrive and researchers hope that by interpreting it they can develop new drugs to fight infections without bacteria dev... Read More
Most of the planet’s carbon is neither in the forests nor the atmosphere. It is in the soil under your feet. US scientists think that they have identified the mechanism that keeps most of this awesome treasury of carbon locked away in the soil – or surrenders much more of it back to the atmosphe...

Norwegian researchers in Trondheim have achieved surprising results by exploiting nature's own ability to clean up after oil spills.
We all know that marine bacteria can assist in cleaning up after oil spills. What is surprising is that given the right kind of encouragement, they can be even mo... Read More
A Connecticut law requiring flu shots for children entering preschool or daycare has reduced flu-related hospitalizations of young children by 12 percent, according to a new study. The jump in flu vaccinations of young children -- to 84 percent in 2012-2013 from about 68 percent in 2009-2010 -- ... Read More
Perhaps you’ve punched out a paper doll or folded an origami swan? TED Fellow Manu Prakash and his team have created a microscope made of paper that's just as easy to fold and use. A sparkling demo that shows how this invention could revolutionize healthcare in developing countries … and turn al... Read More

The system that allows the sharing of genetic material between bacteria – and therefore the spread of antibiotic resistance – has been uncovered by a team of scientists at Birkbeck, University of London and UCL.
The study, published today in Nature, reveals the mechanism of bacterial type IV ... Read More
Serratia marcescens is a bacteria that has earned a bad reputation for infecting people in hospitals. It may deserve an even worse reputation. It might have made people believe, for hundreds of years, that the blood of Christ was miraculously appearing in communion wafers.

When a clear sunny day turns into clouds, people used it to explain their grave mood without taking into consideration how clouds can affect global warming in the atmosphere. But University of Georgia marine researchers have discovered the process of an anti-greenhouse gas known as DMSP (dimethy... Read More
