In the moist, dark microbial rainforest of the intestine, hundreds of species of microorganisms interact with each other and with the cells of the host animal to get the resources they need to survive and thrive.
Though there's a lot of competition in this vibrant ecosystem, collaboration is... Read More
Nano-biotechnologists have reported the discovery of a new, third class of biomotor, unique in that it uses a "revolution without rotation" mechanism. These revolution biomotors are widespread among many bacteria and viruses.

The mystery of alcoholic fermentations was uncovered in the first half of the 19th century by Cagniard-Latour (1837) in France, and Schwann (1837) and Kützing (1837) in Germany, based on microscopic studies but not without controversy. The great German organic chemist Justus Liebig did not like ... Read More
Dr. Tom Solomon is Director of the Institute for Infection and Global Health at the University of Liverpool. In this video he speaks with Vincent Racaniello about the 2014 outbreak of Zaire ebolavirus in West Africa. Dr. Solomon discusses why the epidemic has spread, how it might be curtailed, t...

Until this year, the world had recorded 1,640 deaths from Ebola since the virus was discovered in 1976.
Then Ebola appeared in West Africa.
So far this year, 887 people have died of Ebola in West Africa, the World Health Organization said Monday.
To put that into perspective, more than ... Read More
Back in 2008, doctors in Cambodia made a worrisome discovery. They were having a hard time curing some people of malaria.
Even the most powerful drug wasn't clearing out the parasite from patients' blood as quickly as it should. Malaria had evolved resistance to the last medicine we have agai... Read More
As the deadly outbreak of Ebola in West Africa continues to claim lives, Wellcome Trust director Dr Jeremy Farrar calls for Africans to be given access to experimental Ebola medication. This joint statement with Prof David Heymann, head of the Chatham House Centre on Global Health Security, and ... Read More
The vaccine used to protect against tuberculosis disease, bacillus calmette-guerin or BCG, also protects against tuberculosis infection, mycobacterium, as well as protecting against progression from infection to disease, finds new research. The BCG vaccine has been subject to numerous trials and... Read More
It came as a surprise to me recently to realize how much is known about the immune responses of plants and, moreover, how much there is to know. There is, I found, detailed molecular information about how our botanical cousins defend themselves against the onslaught of infectious agents. Perhaps... Read More
Growth of Serratia marcescens bacteria on bread: The Bacteria were suspended in tap water and placed on the bread. It was incubated foe 3 days in RT. Read More
A U.S. hospital caring for two Americans carrying the deadly Ebola virus has tapped biosafety experts to ensure doctors, nurses and other staff do everything needed to prevent the virus from escaping from an isolation ward in Atlanta.
The two patients, humanitarian aid workers who became infe... Read More
Bugs that can co-operate best with each other are most likely to be able to jump to new species, including humans, a new study shows.
Bacteria interact by releasing molecules to help them adapt to their environment – for example, when killing competing infections in their victim. They co-ord... Read More
The body’s assailants are cleverer than previously thought. New research from Lund University in Sweden shows for the first time how bacteria in the airways can help each other replenish vital iron. The bacteria thereby increase their chances of survival, which can happen at the expense of the p... Read More
On Friday afternoon, the federal Centers for Disease Control and Prevention posted a guide explaining how hospitals should manage Ebola patients. Hospital workers entering a patient's room should wear:
- Gown (fluid resistant or impermeable)
- Eye protection (goggles or face shield... Read More

After recording TWiV 296 with Linfa Wang, we drove to a nearby golf course. There we watched a colony of grey-headed flying foxes awaken and fly into the night.
Vincent visits the Australian Animal Health Laboratory in Geelong, Australia and speaks with Linfa about his work on bats and bat viruses.
Hosts: Vincent Racaniello
Scientists for Science are confident that biomedical research on potentially dangerous pathogens can be performed safely and is essential for a comprehensive understanding of microbial disease pathogenesis, prevention and treatment. The results of such research are often unanticipated and accrue... Read More
