These days I am putting the finishing touches on a hybrid algorithm that optimizes a system (a gamma-ray observatory) by combining reinforcement-learning with gradient descent. Although I published an optimization strategy for that application already, I am going back to it to demonstrate a case where the simultaneous>
Telescopes and inference told scientists that the asteroid Bennu was covered in large swaths of fine regolith, smaller than a few centimeters. What they found when OSIRIS-REx arrived at Bennu was something else: A surface covered in boulders. The surprise lack of fine regolith became even more interesting when mission>
People said it couldn't be done, but researchers from the University of Pittsburgh and the U.S. Department of Energy National Energy Technology Laboratory (NETL) in Pittsburgh demonstrated a molecular chain reaction on a metal surface - a single electron caused a self-perpetuating chain reaction that rearranged the>
In a previous article I demonstrated how to use a One Time Pad cipher using a pen, paper, and Scrabble tiles (or Boggle cubes). If used correctly, One Time Pads cannot be broken by the NSA or any intelligence service on Earth because the One Time Pad keys use a randomly generated set of letters or numbers to encrypt>

The quality and size of electronic display screens may have gotten a lot better. We may also soon see erasable and rewritable electronic paper and ink that can change color electromagnetically, thanks to University of California, Riverside nanotechnologists who have succeeded in controlling the color of very small>
