Method Allows Fast Analysis of Cancer Mutations

October 23, 2014 7:00 am | by MIT, Anne Trafton | News | Comments

Sequencing the genomes of tumor cells has revealed thousands of genetic mutations linked with cancer. However, sifting through this deluge of information to figure out which of these mutations actually drive cancer growth has proven to be a tedious, time-consuming process. Now, researchers have developed a new way to model the effects of these genetic mutations in mice.

Researchers Sequence Early Modern Human DNA

October 23, 2014 7:00 am | by Max Planck Institute | News | Comments

A research team has sequenced the genome of a 45,000-year-old modern human male from western Siberia. The comparison of his genome to the genomes of people that lived later in Europe and Asia show that he lived close in time to when the ancestors of present-day people in Europe and eastern Asia went different ways.
