Can you write down your solutions to the clues?
I also tried to solve them, but it didn't quite fit with Mental, but I managed to connect it to Gur:
Clue 2: "Registration: 04.03.2006". George Gamow, a famous Soviet-American physicist, was born on March 4th, and according to Wikipedia, he "first clearly formulated the problem of the genetic code." -> phrase from the newspaper "Let me dig into your genotype."
03.03.2006
Sincerely,
Gur
