Episode notes

Rice is a food that feeds the world and making it increase its yield could make it do even more. Scientists have managed to tweak some ns and rice in order to increase its yield by forty %. They've been looking at a jeans that control jeans. These things, theyare alled regulatory jeans. I gues ther'e kind of a switch that switches on maybe other things. So maybe ye could find one jean that would switch on a bunch of things, like make a plant grow bigger, or make it photo synthesize more,. Or make its roots more efficient at absorbing nutrient from the soilye. Ye. Was certainly a sobering story, flora. It's

00:45 Working out how the ability to digest milk spread

Humans have been drinking milk for thousands of years, but it seems that they were doing so long before the ability to digest it became prevalent. Then around 2000 years ago, this ability became common in Europe, presenting a mystery to researchers – why then? Now by analyzing health data, ancient DNA, and fats residues from thousands of ancient pots, scientists have worked out what caused this trait to suddenly spread throughout Europe.

11:21 Assessing the addiction potential for therapeutic ketamine

Ketamine has shown great promise as a fast-acting antidepressant, but there have been concerns about the risks of addiction relating to this therapeutic use. Now, a team have looked in mice to see whether ketamine causes the behavioural and neuronal changes characteristic of addictive substances. They find that ketamine likely has a low addiction risk, which could inform future prescribing decisions in humans.
