Pregnancy's effect on 'biological' age, polite birds, and the carbon cost of home-grown veg
In this episode:
Growing a baby leads to changes in the distribution of certain chemical markers on a pregnant person’s DNA, but new research suggests that after giving birth, these changes can revert to an earlier state.

A Japanese tit (Parus minor) will flutter its wings to invite their mate to enter the nest first. Use of these sorts of gestures, more complex than simply pointing at an object of interest, were thought to be limited to great apes, suggesting that there are more non-vocal forms of communication to be found in the animal kingdom.

Research have estimated that the carbon footprint of home-grown food and community gardens is six-times greater than conventional, commercial farms. This finding surprised the authors — keen home-growers themselves — who emphasize that their findings can be used to help make urban efforts (which have worthwhile social benefits) more carbon-efficient.
