According to healthcare experts, the fact that genetic sequencing could be used to determine all there is to know about a certain disease is misleading sometimes, and a straight-up lie most of the times. They add that functional tests also play a critically-important part in figuring out what plagues a patient.

Scientists recently published the results of a new analysis, showing that the appearance life has here on Earth may be inscribed in the very laws of nature and reality. This, the team says, happens because of the way life is coded to emerge and develop, and also due to its basic components. A mathematical analysis of... |
