Shingles Vaccine Coverage Low in Elderly Americans - ICAAC 2013

Almost 1 out of every 3 people in the United States will develop shingles during their lifetime. Despite the approval and recommendation by the FDA of a shingles vaccine for adults over 50, only 16% of American seniors over 60 are vaccinated. Vaccinations are even lower for those aged 50-60. A... Read More

First Look at How Individual Staphylococcus Cells Adhere to Nanostructures Could Lead to New Ways to Thwart Infections

The bacterium Staphylococcus Aureus (S. aureus) is a common source of infections that occur after surgeries involving prosthetic joints and artificial heart valves. The grape-shaped microorganism adheres to medical equipment, and if it gets inside the body, it can cause a serious and even life-t... Read More

Fossil viruses preserved in hot spring bacteria

Fossilized microbes have provided scientists many clues about origins of life. By comparison, little attention is given to viruses in the fossil record. Although technically non-living, there is no question these tiny packets of protein-sheathed DNA have shaped the evolution of most life on eart... Read More

TWiP 55 letters

Jessie writes:


Hi Vince and Dick!


Has anyone volunteered to do transcripts for TWIP? I love this show, and I'd love to be able to contribute in some way. Forgive me if transcripts already exist and I'm just not finding them on the website. If no one is already... Read More

Antibiotics An Effective Treatment For Chronic Back Pain

A groundbreaking study from a well-renowned team of Danish researchers could bring unprecedented relief for sufferers of chronic back pain.

According to the study, which appeared in the European Spine Journal, as much as 40 percent of chronic lower back pain is caused by bacteria. Treating th... Read More

Earth 'Surrounded By Bacteria Bubble'

Planet Earth is surrounded by a bubble of live bacteria scientists have found.

According to a report by Popular Science the colonies of bacteria live at about 33,000 feet - roughly the cruising height of a passenger jet.

But while it might sound strange, it appears the phenomenon is a cruc... Read More

Bacteria 'use language to thrive'

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

ICAAC 2013 C.difficile Update with Kelly Daniels and Philip Chung

Patients getting medical care can catch serious infections called healthcare-associated infections (HAIs). While most types of HAIs are declining, one -- caused by the bacterium Clostridium difficile --continues to grow. C. difficile causes diarrhea linked to 14,000 American deaths each year. Pa...

Microbes are going to save the world | Bonnie Bassler (video)

Should we only consider bacteria as harmful to our bodies?

Bonnie Bassler is a molecular biologist who has made a stunning discovery: bacteria 'talk' to each other using chemical signals that enable them to act as a unit, mount attacks and coordinate defence. This phenomenon of bacterial com... Read More

A Simple Tree Branch Can Become a Backyard Water Filter

For people in too many developing countries, clean water is often a luxury. Chlorine treatments are too expensive for small villages, boiling requires a hefty investment in fuel, and UV radiation demands regular high-tech maintenance. But now, scientists say that a simple, inexpensive water filt... Read More

The Microbes Living in Our Bodies Were Probably Once Evil Pathogens

Like pretty much all multi-cellular organisms, humans enjoy the benefits of helpful bacteria. (As you may have heard, there are more bacteria in the human body than cells.) These mutualistic microbes live within the body of a larger organism, and, like any good long-term houseguest, help out the... Read More

E. coli engineered to produce the enzyme carbonic anhydrase, which converts carbon dioxide to bicarbonate and then to calcium carbonate,... Read More

Unnecessary TB deaths to be thing of the past thanks to new mobile drug resistance test device

Thousands of deaths from tuberculosis (or TB), an infectious bacterial disease, could be prevented using a new hand-held device that is being developed to detect potentially fatal drug resistance in less than 15 minutes.

Currently neither the TB infection itself, nor those people with strains... Read More

Oral bacteria resulting from poor dental hygiene shows a potential association with Alzheimer’s disease

Researchers examined samples from the brains of patients with and without dementia and found lipopolysaccharide, a component of Porphyromonas gingivalis, an oral bacterium, in four out of 10 Alzheimer’s disease brain samples.

“This clearly shows that there is an association between oral bacte... Read More
