How humans adapted to digest lactose — after thousands of years of milk drinking
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.

The promise behind the hype
16:41|Peptides — short chains of amino acids — have become huge online. The popularity of these molecules has skyrocketed and they are now the latest cure-all trend on social media.But what does the science say about their effectiveness? Animal research suggests that that some of these experimental peptides hold promise, but evidence they work in people is lacking.This is an audio version of our Feature: Is the peptide craze backed by science?
