TED: Lever vi i en simulation?

All life on Earth— living and inanimate, microscopic and cosmic— is governed by mathematical laws with apparently arbitrary constants. And this opens up a question: If the universe is completely governed by these laws, couldn’t a powerful enough computer simulate it exactly? Could our reality actually be a detailed simulation set in place by a more advanced civilization? Zohreh Davoudi investigates.

TED: Nästa revolution – programmera våra celler

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 medicine, agriculture and energy.
