Diana is incredibly fragile, even when it's frozen time. Most difficult problem is contamination. First step is using a dentist's drill to remove the surface of the tooth. Then we use various methods to clean this diane. Eventually we have the dhe dine in a pure form in dissolved in water.
Researchers sequence the oldest DNA ever recovered, and the people bringing art and science together.
In this episode:
00:46 Million-year-old mammoth DNA
This week, researchers have smashed a long-standing record by sequencing a genome that's over a million years old. They achieved this feat by extracting DNA from permafrost-preserved mammoth teeth, using it to build-up a more detailed family tree for these ancient animals.
12:18 Putting art into science (and science into art)
Art and science are sometimes considered disparate, but when brought together the results can be greater than the sum of their parts. This week we hear from an artist and a scientist on the benefits they found when crossing the divide.
We discuss some highlights from the Nature Briefing. This time, a neanderthal gene makes brain-like organoids bumpy, and uncovering the original location of Stonehenge’s stone circle.
