What is CRISPR-Cas?

CRISPR-Cas is a powerful new technology that is revolutionizing biology. It’s like cut and paste for DNA.

Scientists are already using CRISPR to introduce genes for disease resistance into wheat and insert malaria-blocking genes into mosquitoes.

 

Superbugs – the game

You can now destroy deadly bacteria and keep humanity’s precious antibiotics working for as long as you can in a free game on your mobile phone.

The story of this casual, real-time puzzle game comes straight from today’s headlines: The rise of superbugs, resistant bacteria which can’t be killed by the drugs we rely on to fight infection.

You can download the game for iOS and Android systems here

 

 

Mutations – selection: the bacteria resist

This animation shows a young medical assistant giving a presentation about the principles of evolution. The genetic information of each living being is subject to modifications. Mutations can lead to bacterial resistance towards antibiotics. When in contact with the antibiotic, the resistant bacteria will be the only ones to survive, multiply, spread all over and finishing up to be a big problem for medicine.

What is natural selection?

Natural selection can be defined as the process by which random evolutionary changes are selected for by nature.
When coupled with descent with modification, Natural Selection can cause a population to evolve for fitness within a given environment over multiple generations.

Watch this lovely video which explains Natural Selection.

 

How does cooperation evolve?

If evolution is all about “survival of the fittest”, how does cooperation evolve? Living things form cooperative relationships all the time. Research done by applying mathematics to biology is helping us understand the evolution of cooperation. Cooperation has caused some of the major evolutionary steps in the history of life, including the step from single celled creatures to multi-cellular plants and animals.
