Why are drug prices so high? Investigating the outdated US patent system | Priti Krishtel

1/16/2020
Between 2006 and 2016, the number of drug patents granted in the United States doubled -- but not because there was an explosion in invention or innovation. Drug companies have learned how to game the system, accumulating patents not for new medicines but for small changes to existing ones, which allows them to build monopolies, block competition and drive prices up. Health justice lawyer Priti Krishtel sheds light on how we've lost sight of the patent system's original intent -- and offers...

The next software revolution: programming biological cells | Sara-Jane Dunn

11/1/2019
The cells in your body are like computer software: they're "programmed" to carry out specific functions at specific times. If we can better understand this process, we could unlock the ability to reprogram cells ourselves, says computational biologist Sara-Jane Dunn. In a talk from the cutting-edge of science, she explains how her team is studying embryonic stem cells to gain a new understanding of the biological programs that power life -- and develop "living software" that could transform...
