Sizes in Biology

Dear colleagues,

An excellent tool is available to get a feeling about molecular sizes in Biology.

The tool is available here and was developped by “Learn Genetics” program from the University of Utah.

You can have a short movie on it below, but please check the original one from here!!!

What you always wanted to know about viruses

In animation, Cool stuff, Swine flu, virus on April 30, 2009 at 10:02 am

Considering that swine flu is here everywhere and many became interested in viruses, I compiled here a few videos that might give you an update about viruses, virology, vaccine production and how a vaccine acts. Feedback and questions are welcome at




Where are the swine flu cases?

See actual status here

or check it in GoogleMaps here:

An overview of the status by 20090430:


How does influenza spreads and what happens with it in our body?

The life of a virus

The structure of viruses

Vaccine production(description and images).

Vaccine production at Sanofi (video).

How does the vaccine act?

Injection of the vaccine

More about pandemics, and vaccination here.

How microarrays can be used for rapid characterization of viruses: here.

Stay tuned!

Bird flu solved, swine flu arrived!

In Cool stuff, News, virus on April 29, 2009 at 4:12 pm

The bird flu solved by vaccines, now comes the swine flu.

Pandemics shaped the human population in past and probably in future. One of the most destructive influenza pandemics in the last century was the Spanish Flu which caused the death of 25-40 million people. More info about the pandemics here. The very last thread to cause a pandemic is the virus called A/H1N1, or swine flu, or Mexican flu.

Rapid diagnostic tests will be probably be PCR based. A very interesting microarray based virus characterization tool is described here.

Influenza vaccines are produced by quite a lot of manufacturers in the world. You can have a list of the manufacturers here.

A small Hungarian company is a word leader in vaccine development. Omninvest was one of the first who produced the anti H5N1 vaccine. It is good to draw the conclusions of the Bird Flu vaccine development, a detailed overview can be found here.

Today Omninvest announced that they made all the preparatory steps needed to start to develop a Swine Flu vaccine. Once the sample virus arrives they can start the development of inactivated viruses that can be used for the development of the Swine flu vaccine. While US based CDC researcher Ruben Donis announced that the “reference strain” would be available at the beginning of May, the Hungarian news agency MTI released the information that samples that could be used for further development migh arrive in days.
