Science: RNA Test Detects Pre-Eclampsia, Machine Vision, Recycling Urine

RNA in blood reveals signs of pre-eclampsia before symptoms occur, and the issue of urine in our sewage and what can be done about it.

In this episode:

00:46 Predicting pre-eclampsia

Cell-free RNA circulates in the blood and can give clues as to what is going on in the body. This can be used to detect disease before symptoms occur. Now researchers have analysed cell-free RNA in pregnant people and have found it can give early warning signs of a serious, and sometimes fatal, disorder of pregnancy — pre-eclampsia.

09:55 The problems of pee

Sewage and the way it is managed can cause serious problems, for example contaminants in waste can lead to harmful algal blooms. One of the major causes of this is urine, and so some researchers have been promoting a deceptively simple solution — separate out the urine.

16:40 Briefing Chat

We discuss some highlights from the Nature Briefing. This time, how China has planned to make this year’s Winter Olympics carbon neutral, and how a new radio telescope in Namibia will help us understand black holes.
