Humans share with fish about 70% of the genes that encode proteins, but only 0.5% of the genes belonging to the control group that produce lncRNA. Image: pixabay.

Genetic recycling: new roles for ancient genes

The experimental system: two nostrils from which exit ultrasonic beams of excited helium atoms (in blue) and of argon atoms or hydrogen molecules (in red). The blue beam passes through a magnetic device (in yellow) which causes it to bend, and merges with the red beam - then the argon atoms or hydrogen molecules undergo ionization, and enter the detector. The picture above shows a cross-section of the magnetic device
