For a long time, so-called satellite DNA was considered largely worthless. Now, ETH Zurich researchers have shown in fruit flies that these repetitive sections of genetic material act as a kind of barcode, enabling the correct chromosomes to recognise one another.
The closer two people grow, the more alike their brains work – or so the assumption goes. Two ETH Zurich studies challenge this idea by examining the brain activity of younger and older adults who drew together over several weeks. Despite growing closer, the similarity of their brain activity did not simply increase.
Researchers from ETH Zurich are laying a fibre-optic cable on the Gorner Glacier in Valais to investigate its internal structure. Their findings have uncovered more damage within the ice than initially anticipated.
