SHOULD WE EDIT THE NATURAL WORLD?
BBC Focus - Science & Technology
|Summer 2021
A process that began centuries ago with selective breeding has developed into genetic modification. HAYLEY BENNETT explores the consequences of using these controversial tools
Back in the 1990s, we debated the risks and benefits of genetically modified (GM) crops. Some found the idea of eating ‘non-natural’ foods unsavoury, while others saw the merits of crops with increased yields and resistance to pests, drought and disease. Today, as pressures on farming intensify under climate change, we’re seeing a new debate. The difference now is that scientists have better tools for editing genomes and we’re not just talking about using them in crops.

DOES MY BRAIN LIVE A LITTLE IN THE PAST?
Yes, your brain does live a little in the past. It can't help it. The information it receives via your senses is always a little out of date. Whether it's light entering the retinas in your eyes, or sounds vibrating the hairs in your ears, it not only takes time for the data to arrive, but your brain then has to process it.

CAN YOU STOP YOUR SENSE OF TASTE DULLING AS YOU AGE?
Sometimes I hear people say that food just doesn't taste the same as they get older. It's tempting to blame this on age, but there are other factors at play, too.
