Like a protective tent over a colony of harmful bacteria, biofilms make the treatment of skin infections especially difficult. Microorganisms protected in a biofilm pose a significant health risk due to their antibiotic resistance and recalcitrance to treatment, and biofilm-protected bacteria ac... Read More
Dear Vincent & Dickson… and Daniel,
I always enjoy listening to TWIP here in Kona, Hawaii.
Our weather today is 79ºF and clear but we have just experienced a record 25-year overnight low of 54ºF,
Researchers at Harvard and Yale have used some extreme gene-manipulation tools to engineer safety features into designer organisms.
This work goes far beyond traditional genetic engineering, which involves moving a gene from one organism to another. In this case, they're actually rewriting th... Read More
Dear TWIM hosts,
I enjoyed episode 76, "Genetic biopixels and a pathogenic sweet tooth". I really enjoyed hearing about the course that Dr. Schaechter teaches and in particular the work his students did in developing the biosensor. I would like to ... Read More
A UNSW-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis.
The function in the algae of this quantum effect, known as coherence, remains a mystery, but it is thoug... Read More

I came across this paper and thought it sounded interesting for a discussion on TWiP:
Colonisation resistance in the sand fly gut: Leishmania protects Lutzomyia longipalpis from bacterial infection
Pseudomonas aeruginosa isolated from sputum into department of Microbiology - Riuniti Hospital Reggio Calabria .
This strain of Pseudomonas secretes brown/black extracellular pigment: pyomelanin.

The TWiV team discusses transmission of Ebola virus, and inhibition of Borna disease virus replication by viral DNA in the ground squirrel genome.
Romance often sparks between colleagues, and scientists are no different. Nature profiles four super-couples who have combined love and the lab.
When physicists Claudia Felser and Stuart Parkin were introduced at a conference on applied magnetics, they felt an immediate attraction. But then, ... Read More
Recording together for the first time, the TWiV team celebrates their 300th recording at the American Society for Microbiology headquarters in Washington, DC, where Vincent speaks with Dickson, Alan, Rich, and Kathy about their careers in science.

The Global Virus Network (GVN) announced today the launch of a Task Force on HTLV, Human T-Lymphotropic Virus (HTLV), the world's first known human retrovirus and only known leukemia-causing virus. Experts from 11 countries*, led by Dr. Robert Gallo, GVN co-founder and scientific director and di... Read More
When children are starving, the bacteria that live in their intestines may determine whether they can be saved, scientists working in Bangladesh are reporting. And they say it may become imperative to find a way to give children bacteria as well as food.
The study, done by researchers from Wa... Read More
UK bioscience funders BBSRC and scientists from Oxford Brookes University teamed-up to run Giant Germs – an event tailored specifically to the blind and visually impaired. The day allowed visitors to discover the microscopic world of microbes for the very first time thanks to 3D printing technol... Read More
This fungal colony, in association with a few others, was grown on SDA and appears to be an antibiotic producer. The compounds that it's producing appear orange and red. The colony grew and began producing compounds on the agar after five days incubation at 30 degree Celsius. This plate is part ... Read More
Researchers at the University of Virginia School of Medicine have discovered how the deadly Ebola virus punches its way into the cytoplasm of cells. The finding identifies an important target for blocking the infection process of this incurable disease that many fear may be used for bioterror.

As many as 75 scientists working in government laboratories may have been exposed to live anthrax bacteria, the Centers for Disease Control and Prevention said on Thursday. The scientists are being offered treatment to prevent infection.
The potential exposure occurred after researchers worki... Read More
