New Zeiss microscope peers into secret lives of cells

“See those white sparks?” asks Kirk Czymmek, as he points to the video on his computer screen of a highly magnified heart cell in action.

Discovery of key mechanism in bacterial communication

A team of Princeton scientists has discovered a key mechanism in how bacteria communicate with each other, a pivotal breakthrough that could lead to treatments for cholera and other bacterial diseases.

New understanding of how bacteria survive in hostile environments

Using an innovative device with microscopic chambers, researchers from four institutions, including Johns Hopkins, have gleaned important new information about how bacteria survive in hostile environments by forming antibiotic-resistant communities called biofilms.

Beneficial bacteria in the appendix aid digestion after infection

Long denigrated as vestigial or useless, the appendix now appears to have a reason to be – as a “safe house” for the beneficial bacteria living in the human gut.

Space flight makes bacteria more infectious

Space flight has been shown to have a profound impact on human physiology as the body adapts to zero gravity environments.

New method to detect infection in prosthetic joints

A team of Mayo Clinic researchers has discovered a new, more accurate diagnostic test to detect infection of prosthetic joints, potentially leading to better treatment options and patient outcomes.

Bacteria - you can live without 'em, but it won't do you any good!

The finding challenges the conventional wisdom that even harmless bacteria – and the immune response they provoke – suck up the energy of the host organism and hasten its death.

New diagnostic tool to detect infection-causing bacteria

Infection-causing bacteria can't hide from researchers at Northern Arizona University, who recently helped develop the first diagnostic tool to detect them.

Bacterial biofilms

In one of the first potential applications of synthetic biology, an emerging field that aims to design and build useful biomolecular systems, researchers from MIT and Boston University are engineering viruses to attack and destroy the surface biofilms that harbor harmful bacteria in the body and on industrial and medical devices.

Summer's here so look out for Legionnaires disease

Summer's here and the living isn't always so easy especially if youre in the hospital. Patients who are vulnerable to infection run a greater risk of contracting Legionnaires disease, a severe form of pneumonia, during warm, humid weather, according to a study published in the Journal of Infectious Diseases.

Researchers develop way to calculate rate of gene transfer among bacteria in the environment

Scientists from the University of California-Davis recently developed a mathematical model of the rate of gene transfer among bacteria in the environment.

Surprising new theory on antibiotic resistance

A surprising new theory developed at the University of Nebraska Medical Center (UNMC) in Omaha, Nebraska, suggests that some bacterial cells act as "suicide bombers" in cell communities, with the altruistic intention of dying for the common good - and in the process, strengthening other cells that then become resistant to antibiotic drugs.

Communication between bacterial cells

To each other: by using signal substances they inform their neighbours as to whether or not it is worth switching certain genes on or off.

Trojan horse approach designed to defeats drug-resistant bacteria

A new antimicrobial approach can kill bacteria in laboratory experiments and eliminate life-threatening infections in mice by interfering with a key bacterial nutrient, according to research led by a University of Washington scientist.

Garlic offers hope in cystic fibrosis infection

Garlic has been hailed a wonder drug for centuries and has been used to prevent gangrene, treat high blood pressure, ward off common colds and is even believed by some to have cancer-fighting properties.

New smart anti-microbial approach to preventing tooth decay

Preventing cavities could one day involve the dental equivalent of a military surgical strike. A team of researchers supported by the National Institute of Dental and Craniofacial Research report they have created a new smart anti-microbial treatment that can be chemically programmed in the laboratory to seek out and kill a specific cavity-causing species of bacteria, leaving the good bacteria untouched.

New compounds could make drug-resistant bacteria harmless

Just as the medical world has become concerned over the apparent resistance of some bugs to antibiotics, scientists have made significant progress towards the development of a new generation of antibiotics.
