Scientists may be able to entomb the malaria parasite in a prison of its own making, researchers report. As it invades a red blood cell, the malaria parasite takes part of the host cell's membrane to build a protective compartment. The parasite then starts a series of major renovations that tran...

Rivers and streams could be a major source of antibiotic resistance in the environment.
The discovery comes following a study on the Thames river by scientists at the University of Warwick’s School of Life Sciences and the University of Exeter Medical School.
The study found that greater n... Read More
It may come as a bit of a surprise to learn that bacteria have an immune system - in their case to fight off invasive viruses called phages. And like any immune system - from single-celled to human - the first challenge of the bacterial immune system is to detect the difference between "foreign"... Read More
Fecal transplants can be life-saving for people with stubborn bacterial infections, but they're not for the faint of heart. So doctors have come up with a way to make them more palatable – the frozen poop pill.
People infected with Clostridium difficile suffer debilitating diarrhea, but the b... Read More
Bacteria are as individual as people, according to new research by Professor Peter Young and his team in the Department of Biology at the University of York. Bacteria are essential to health, agriculture and the environment, and new research tools are starting to shed more light on them.

A probiotic that prevents obesity could be on the horizon.
Bacteria that produce a therapeutic compound in the gut inhibit weight gain, insulin resistance and other adverse effects of a high-fat diet in mice, Vanderbilt University investigators have discovered.
“Of course it’s hard to spec... Read More
For cellphone whisperers, families that live near highways, airports or trains, music-loving commuters, and even individual cells, noise is an inescapable fact of life. In everyday human experience, the nuisance is often manageable. Soundproof barriers and noise-canceling headphones help scrub t... Read More
For more than a year, Cornell University's Christopher Mason and his team of researchers have been identifying bacteria in the New York City subway system. And some of the findings might surprise you. Photo: Katie Orlinsky for The Wall Street Journal
The time before the symptoms of a viral infection appear is called the incubation period. During this time, viral genomes are replicating and the host is responding, producing cytokines such as interferon that can have global effects, leading to the classical symptoms of an acute infection (e.g....

In 1976, a group of health workers took a pair of film cameras to what was then known as Zaire and documented their discovery of a new, deadly virus.
Today we know that virus as Ebola.
A 27-year-old Belgian microbiologist named Peter Piot and his colleagues were the first to scientifically... Read More
Rapid detection of antibiotic resistance is vital in assessing the appropriate antibiotic therapy for an infection. Participants will present data on two new inex... Read More
As the focus of the Ebola issue shifts from management to recovery and prevention, an array of post-infection effects have cropped up in survivors of the virus. Vision and hearing problems have resulted from infection with the Ebola virus, and researchers are now faced with the task of determin... Read More
Modern biology has attained deep knowledge of how cells work, but the mechanisms by which cellular structures assemble and grow to the right size largely remain a mystery. Now, researchers may have found the key in a dynamic agglomeration of molecules inside cells.

Engineered E. coli can store long-term memories of chemical exposure, other events in their DNA.
MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well su... Read More
This episode: Genes taken from bacteria may have been important for the evolution of distinct groups of archaea!

A report in Biology Letters shows that the drool of herbivores might help defeat the toxic fungal defences of the plants they graze on.
Grazing or cutting some plants induces a noxious chemical to be produced which deters hungry plant-eaters from revisiting them. The chemicals, called alkaloi... Read More

Your gut is a genius. Inside it exists an astonishing ecosystem of trillions of micro-organisms—more than 10 times the number of human cells in our bodies! This ecosystem of microbes—the human gut microbiota—deeply influences our phy... Read More
The arrival in the United States of a Liberian man infected with the Ebola virus shows how easily the disease can travel and how thin the procedures are, relying heavily on the honesty of travelers and the diligence of airport workers. Some experts say that the system, given its inherent weaknes... Read More
