When I began listening to TWIV almost a year ago, I had just switched majors from philosophy to biology. I am now writing to you good people at TWIM at the end of my first undergraduate summer research gig, where I have had qui... Read More
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
One species of bacteria seems to get many of the perks of sexual reproduction without actually having sex, a new study finds.
Different strains of bacteria called Mycobacterium smegmatis swap large, random bits of DNA prior to reproducing asexually. This process, known as conjugal transfer, p... Read More
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
Bioluminescent art blends science and creativity to create images that can only be seen in the dark. What do you get when you add a chemical engineer, a graphic designer and a research scientist? Beautiful art. In a wondrous combination of nature and design, bioluminescent art involves using nat... Read More
On June 24, 2012, a 60-year-old Saudi man died from severe pneumonia complicated by renal failure. He had arrived at a hospital in Jiddah 11 days earlier, and some of his symptoms were similar to those in severe cases of influenza or SARS, but this wasn't either of those diseases.
This was so... Read More
Cystic fibrosis patients suffer from chronic bacterial infections and thick mucous in their lungs, due largely to a combination of microbial infections and resulting inflammation. A common pathogen, Pseudomonas aeruginosa, which can lay dormant in healthy individuals, becomes virulent in the lun... Read More
I’m reeling from this episode!! The symbiosis, the web of life, the energies, chemicals, organisms of
Liquid hand soap in many public toilets is doing the opposite of improving hygiene, CCTV reports.
One sample was found to have 600 times more than the standard amount of bacteria, bringing it up to fast food ice levels of grossness. Experts warned that use of the soap could result in skin irr... Read More
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...

Improper handling of intravenous saline at a West Virginia outpatient oncology clinic was linked with the first reported outbreak of Tsukamurella spp., gram-positive bacteria that rarely cause disease in humans, in a new report from the Centers for Disease Control and Prevention (CDC). The repor... Read More
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
The H1N1 virus responsible for the 2009 global pandemic is back. State health officials from across the country say the resurgence is resulting in a dramatic rise in flu deaths in young and middle-aged adults and in children this season.
While the reported death tolls so far are only a fracti... Read More
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
The Agriculture Department is reviewing research showing that new bacteria-killing chemicals used in chicken slaughterhouses may be masking the presence of salmonella and other pathogens that remain on the birds that consumers buy, according to records and interviews.
Academic researchers agr... Read More
For a fifth-grade science fair, Evie Sobczak found that the acid in fruit could power clocks; she connected a cut-up orange to a clock with wire and watched it tick. In seventh grade, she generated power by engineering paddles that could harness wind. And in eighth grade, she started a project t... Read More
This episode: Gut bacteria seem to be important for different kinds of anti-cancer chemotherapy treatments!
(9.4 MB, 10.25 minutes)
As public health officials sound the alarm about the global spread of drug-resistant bacteria, researchers are working to develop more effective antibiotics to counter this dangerous trend. Now, results from a team including a Princeton University scientist offer a possible solution that uses th... Read More
