00:03:26 The recent discovery of dunes on Pluto surprised planetary scientists. With very little atmosphere or wind, what could cause them?
00:11:48 A sample from Mars, analysed by the Curiosity rover, has found organic molecules - the building blocks of life.
00:18:25 One of the most famous psychology experiments, the Stanford marshmallow test, looked at delayed gratification in children back in the 1960s and 1970s. It's now been reproduced, a lot more rigorously, and the results are very different.
00:24:32 A proof-of-concept blood test can determine how far a long a woman is in her pregnancy, and how likely she is to give birth ahead of term.
00:28:22 An emerging field of diagnostics, liquid biopsy, is seeing impressive results. Recent studies correctly diagnosed people with ovarian and liver cancers 80 percent of the time.
00:31:51 Planet Nine is an exciting hypothesis that goes part of the way towards explaining the strange orbits of many rocks in the Kuiper Belt. But another idea could answer a lot of the same questions, without the need for a giant undiscovered planet.
Dr. Mick Vagg is a rehabilitation and pain medicine specialist, and a Clinical Senior Lecturer at Deakin University.
