This episode: New giant virus discovered, with a genome larger than that of some eukaryotes!
Viruses are biological pirates, invading cells and hijacking their machinery to reproduce and infect again. Research at Harvard Medical School is shedding new light on the battle line where viral and cell membranes meet, and the key role of a protein grappling hook with which the influenza virus...

Although as recently as 1980 measles was estimated to cause 2.6 million deaths globally, due to highly effective and safe vaccines, measles elimination has been achieved in a number of countries globally as well as in the region of the Americas. Expansion of measles control strategies and activi... Read More

Does beer have anti-virus powers? According to a new study funded by Japanese beer company Sapporo Breweries, a "key ingredient" found in the world's most popular alcoholic beverage may very well help stave off winter sniffles.
Researchers at Sapporo Medical University found that humulone, a ... Read More
Previous research has shown that the overuse of antibiotics has a hand in promoting an antibiotic-resistant strain of bacteria and now a new study published in the journal mBio has found that an antibiotic common to soaps and hand sanitizers actually promotes the growth of Staphylococcus aureus ...

Exposure to cigarette smoke has long been associated with increased frequency of respiratory infections—which are harder to treat in smoke-exposed people than in those who lack such exposures. Now Ritwij Kulkarni of Columbia University, New York, NY, and colleagues show that cigarette smoke actu... Read More
