If We Can Make Genetically Engineered Designer Babies - Should We?
Episode 377
Considered too dangerous and unreliable a few years ago, the technology for gene editing babies is advancing fast. Improved methods of using CRISPR gene editing are making the technique safer and more targeted. But does that mean we should be creating designer babies?
A new, more powe…
Breakthrough Synthetic Cell Has Just Reproduced - But Is It Alive?
Episode 382
Scientists have created a synthetic cell with just 36 genes that can copy DNA and replicate. In an attempt to create a “minimal cell”, a team led by professor Kate Adamala have built “SpudCell” from the ground up, using non-living components.
But is it alive - and is it dangerous? Des…
Climate Crisis Is Triggering Global Food Shortages - New Predictions Are Devastating
Episode 386
The climate crisis is having a significant impact on yields of crucial food crops. Losses of maize, wheat and soybeans alone are costing $20 billion a year due to heat and drought. New estimates expect this to rise to $160 billion per year by 2100 - although that could be an underestim…
Climate 2026: Record Heat, Tens of Thousands Dead, Mass Evacuations
Episode 389
Europe is burning through another summer of extreme heat. Temperatures are soaring across the continent, wildfires are forcing mass evacuations in France and Spain, and scientists warn that heatwaves are becoming more frequent, more intense and longer-lasting as the climate warms.
Th…
Wildfires Changed Human Evolution - Is It Happening Again?
Episode 392
Ancient wildfires may have shaped the course of human evolution. A reconstruction of the environment in East Africa 1.75 million years ago suggests a particularly volatile period of climate change made our species adapt rapidly.
Climate swings may have led our species to develop sophi…
How to Be Hopeful: Caitlin Moran and New Scientist Look to the Future
