Laurene Mascola's distinctive voice and laugh has won my heart this month. I found that when TWiM came up for the third time in my playlist the last couple weeks, I kept listening just for a fix. She should be a star.
I'm glad you had a good reaso... Read More
When it comes to infecting humans and animals, bacteria need a helping hand.
Kansas State University biochemists have found the helping hand: groups of tiny protein loops on the surface of cells. These loops are similar to the fingers of a hand, and by observing seven individual loops on the ... Read More
The TWiVers discuss the growing Ebola virus outbreak in West Africa, and an epidemic of respiratory disease in the US caused by enterovirus D68.
Inside the filters of the aquariums harboring hundreds of species of molds and other microorganisms. In this photo we took a some part of the fungi who live into filters. The fungi are important microorganisms for health of aquarium. Read More
The campaign is called "Kick Back Ebola." But the posters pack a punch.
Sierra Leone has reported over 700 suspected Ebola cases, more than any other country this year. To help stop the outbreak, health workers have put up Ebola awareness signs all over Sierra Leone's seaside capital of Freet... Read More

Melanin produced by a marine bacteria Bacillus spp. has shown shown to have good anti-inflammatory activity. The pigment had shown to inhibit inflammatory enzymes cycloxygenase, lipooxygenase, myeloperoxide,NO synthase in vitro at a concentration which was non-cytotoxic..This will be a breakthro...

This is a picture of Echinococcus granulosus from an infected liver specimen recently received in our laboratory. It is pictured in a saline wet mount at 40X magnification. The picture shows an evaginated scolex from an immature worm with hooklets.
The adult worm of Echinococcus granulosus l... Read More
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
This is an 3D image of conidiophores of the filamentous fungus Neurospora crassa. Conidiophores are hyphae which differentiate to produce asexual structures named spores or conidia. The image taken using a confocal microscope shows conidiophores stained with a fluorophore which stains components... Read More
The Grand Masters of the TWiV discuss Ebola virus transmission, air travel from West Africa, Ebola virus infectivity on surfaces, the Dallas Ebola virus patient, and Ebola virus in dogs.

A good immune system relies on a key ‘energy producing’ protein in immune cells to develop immunity to vaccines and disease, an international team of scientists has found.
The protein, called HuR (human antigen R) is critical for controlling metabolism in B cells, which make antibodies that a... Read More
