There are bacteria in wine that may be beneficial for people's health, new research finds.
In the study, researchers in Spain isolated 11 strains of bacteria from wine, including strains of Lactobacillus, which are also found in yogurt, as well as Oenococcus and Pediococcus bacteria, which ar... Read More
Our bodies are home to a vast ecosystem of microbes — the microbiome — that has a powerful effect on the brain. Three brain researchers discuss the emerging connection between the brain and the gut, and whether microbes may help treat brain disorders.

Imagine a pill that helps people control diabetes with the body’s own insulin.
Cornell researchers have achieved this feat in rats by engineering human lactobacilli, a common gut bacteria, to secrete a protein called Glucagen-like peptide 1 (GLP-1).
A 2003 study led by Atsushi Suzuki of th... Read More
In the world of health and medicine, the word tobacco usually brings to mind cancer, emphysema and heart disease. But in recent years the plant's tarnished reputation is getting a makeover from the development of pharmaceuticals through an effective, swift and cost-cutting technique that has bee... Read More
Motion is a trait of all life, but detecting the tiny movements of microorganisms requires incredible sensitivity. Now, Swiss scientists say they have developed an extremely sensitive yet simple motion detector that can be built using existing technology.
If a bacterium is alive, it will inev... Read More
A nasal vaccine in development by researchers at The University of Texas at Austin has been shown to provide long-term protection for non-human primates against the deadly Ebola virus. Results from a small pre-clinical study represent the only proof to date that a single dose of a non-injectable... Read More
The love affair between industrial agriculture and the antibiotic industry has come into an uncomfortable spotlight of late. In 2011, 7.7 million pounds of antibiotics were sold to treat sick people in the United States. This compares with a whopping 29.9 million pounds of antibiotics fed to cat... Read More
Several wounded Battle of Shiloh soldiers sat in the mud for two rainy days and nights waiting for the medics. As dusk fell the first night, some of them noticed something very strange: their wounds were glowing, casting a faint light into the darkness of the battlefield. Even stranger, when the... Read More
For hospital workers an outbreak of harmful bacteria in the wards is a nightmare, but what gives bacteria nightmares?
Perhaps the prospect of being eaten alive by a kind of viral parasite called a bacteriophage (bacteria eater): unlike antibiotics, which some bacteria have evolved a resistanc... Read More
When viruses such as influenza and Ebola jump from one species to another, their ability to cause harm can change dramatically, but research from the University of Cambridge shows that it may be possible to predict the virus's virulence by looking at how deadly it is in closely-related species Read More
Why a field researcher from America has exposed his colon to the gut microbiome of a tribesman from Tanzania.
It's not often we encounter a story that begins with a line like this:
“AS THE SUN set over Lake Eyasi in Tanzania, nearly thirty minutes had passed since I had inserted a turkey b... Read More
The use of viruses that kill bacteria as a tool for treating infections are under study again by Western researchers and governments.
For decades, patients behind the Iron Curtain were denied access to some of the best antibiotics developed in the West. To make do, the Soviet Union invested h... Read More
Bacteria may not have brains, but they do have memories, at least when it comes to viruses that attack them. Many bacteria have a molecular immune system which allows these microbes to capture and retain pieces of viral DNA that they have encountered in the past, in order to recognize and destro...

New research shows that the whip-like appendages on many types of cells are able to synchronise their movements solely through interactions with the fluid that surrounds them.
Many different types of cell, including sperm, bacteria and algae, propel themselves using whip-like appendages know... Read More
The World Health Organization expressed worry on Wednesday about a second cluster of Ebola virus patients in Nigeria — in the center of its oil industry — because one of the three confirmed victims was a doctor who had treated patients and socialized after he became contagious.
The doctor, in... Read More
Microbiota buffs repeat it often these days, proudly reminding the public that the microbial cells associated with humans outnumber their host cells by a ratio of ten-to-one. In his letter in the February 2014 Microbe, however, Judah L. Rosner of the National Institutes of Health (NIH) makes a s... Read More
An international team of bioengineers has boosted the ability of bacteria to produce isopentenol, a compound with desirable gasoline properties. The finding, published in mBio®, the online open-access journal of the American Society for Microbiology, is a significant step toward developing a bac... Read More
Scientists have traditionally studied bacteria in large numbers, not individually. Working with tens of millions of cells in a culture flask, they tracked their growth by looking at how much the cells dimmed light passing through a tube.
Using this method, scientists learned that populations ... Read More
When patients take too many unnecessary antibiotics it inches us ever closer to a world where essential drugs are no longer effective. More than two million people in the United States develop antibiotic resistant infection each year and some 23,000 of them die as a result. Yet understanding the... 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
