WHAT PHYSICAL `LIFE FORCE' TURNS BIOLOGY'S WHEELS? (14 MINUTE READ)
[11]
This article tells the story of how scientists figured out how the
flagellar motor worked. The flagellar motor was discovered by Howard
Berg, who set out in the early 1970s to apply his training in physics
to understand how bacteria move. Bacteria move quickly, so Berg had to
invent and build an automatic tracking microscope to keep them in
view. He hypothesized how the mechanism worked 50 years before
scientists discovered how the motor works.
QUANTUM COMPUTERS ARE NOT A THREAT TO 128-BIT SYMMETRIC KEYS (23
MINUTE READ) [12]
Both AES-128 and SHA-256 are safe against quantum computers. No
symmetric key sizes have to change as part of the post-quantum
