New Massive Online Open Courses (MOOC) in Spanish about Pandemics and new viral infections.
An online open course about basic concepts of viruses and pandemics. We answer questions as what is a virus?, how a virus multiplies inside a cell?, what is a pandemic?, why appear new influenza virus ... Read More
We have been using HeLa cells in my laboratory since 1982, when I arrived at Columbia University Medical Center fresh from postdoctoral work with David Baltimore at MIT. I brought with me a line of HeLa cells and used them for 30 years for our research on viruses. Here is a story of how we lost ... Read More
The discovery of antibiotics (also referred to as antimicrobials) is perhaps the most revolutionary outcome in the medical sciences during the twentieth century, and has allowed medical practitioners to treat a wide range of bacterial infections; and therefore, antimicrobials are the most common...

The influenza virus particle is made up of the viral RNA genome wrapped in a lipid membrane (illustrated). The membrane, or envelope, contains three different kinds of viral proteins. The hemagglutinin molecule (HA, blue) attaches to cell receptors and initiates the process of virus entry into c... Read More
The Liberian man who was diagnosed with Ebola virus infection after traveling to Dallas, Texas, was treated with an antiviral drug called brincidofovir. This drug had originally been developed to treat infections with DNA-containing viruses. Why was it used to treat an Ebola virus infection? Read More
Team of researchers guided by Dr.Sarita G Bhat had developed a novel plate based screening technique for DOPA/melanin producing bacteria.Screening was based upon the clear zone formation on a medium suplemented with L-tyrosine.This new approach can be utilized in faster and accurate screening of...

“Stefano, you seem like a smart person. Can I ask you why you decided to take a job with a scientific society?” I had just helped myself to a slice of a very sharp Stilton cheese, after a wonderful dinner supported by wonderful wine. All of a sudden the Stilton seemed even sharper. The question ... Read More
In the year 2000, Kathleen Alexander, DVM, PhD, now a professor, at the Department of Fish and Wildlife Conservation, Virginia Tech, Blacksburg, Virginia, was working as a government veterinarian in Botswana, when a sickly banded mongoose wandered onto the grounds where she worked.

We must change how antibiotics are used and adopt proactive strategies, similar to those used to save endangered species. Preservation of the efficacy of antibiotics and to stabilization of antibiotic-susceptible bacterial ecosystems should be global goals.
We urge all of you to participate i... Read More
In this month's episode of the science show This Week in Evolution, Nels and I discuss the evolution of butterfly wing patterns. In this study of Amazonian butterflies, the authors show that distinct patterns are a consequence of enhancer shuffling. Enhancers are DNA sequences that control trans... Read More
Recently a number of children in California have developed a poliomyelitis-like paralysis. The cause of this paralysis is not yet known, and information about the outbreak is scarce. However, acute-flaccid paralysis is not uncommon (California would be expected to report about 75 cases a year, b... Read More
In a recent New York Times OpEd entitled What We’re Afraid to Say About Ebola, Michaeal Osterholm wonders whether Ebola virus could go airborne:
You can now get Ebola only through direct contact with bodily fluids. If certain mutations occurred, it would mean that just breathing would put one... Read More
The polio eradication and endgame strategic plan announced by the World Health Organization in 2014 includes at least one dose of inactivated poliovirus vaccine (IPV). Since 1988, when WHO announced the polio eradication plan, it had relied exclusively on the use of oral poliovirus vaccine (OPV)... Read More
Nitin Phadnis joins Nels and Vincent to explain how he identified a gene that is responsible for male inviability in hybrids from a cross between two species of fruit flies. Read More
So another Earth Day has come and gone. How did you spend yours? If you spent the entire day asleep, you used about half a kilogram of oxygen. Since I assume that you are alive and kicking, you probably consumed more oxygen than that. If you went about your normal business during the day, you pr... Read More
