Using the principles of evolution to defeat cancer

November 24 marked 164 years since the publication of Charles Darwin's revolutionary "On the Origin of Species," one of the most influential scientific books ever written. In acknowledgement, 24 November is known as "Evolution ...

Mapping the effects of mutations in antibiotic-resistant bacteria

When a bacterium becomes more resistant to one antibiotic, it sometimes becomes more sensitive to another. To better understand this interaction, researchers from the Leiden Institute of Biology (IBL) and the Leiden Academic ...

How superbugs use mirror images to create antibiotic resistance

Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial infection that has become resistant to most of the antibiotics used to treat regular staph infections. Duke University computer scientist Bruce Donald and ...

Computer model identifies drug-resistant mutations

To counter drug resistance, scientists engineer new drugs to "fit" new mutations and thus kill the cancer cell or pathogen. Now, an NIBIB-funded team of Penn State engineers has a new approach for predicting which mutation ...

Engineers model mutations causing drug resistance

Whether it is a drug-resistant strain of bacteria, or cancer cells that no longer react to the drugs intended to kill them, diverse mutations make cells resistant to chemicals, and "second generation" approaches are needed. ...
