New Mineral

"New Mineral Discovered in Deep-Earth Diamond":

A diamond that formed deep in the earth’s mantle contains a mineral never seen before in nature. The discovery is a rare glimpse into the deep mantle and may help reveal new information about the structure of the planet at depths of more than 660 kilometers...

The mineral, calcium silicate perovskite, only forms under the incredibly high pressures that occur deep in the earth...

Relativity And Zero-Knowledge Proofs

Nature: "Experimental relativistic zero-knowledge proofs". (Via G.F.)

In this work, we report the experimental realization of such a zero-knowledge protocol involving two separated verifier–prover pairs. Security is enforced via the physical principle of special relativity, and no computational assumption (such as the existence of one-way functions) is required. Our implementation exclusively relies on off-the-shelf equipment and works at both short (60 m) and long distances (≥400 m) in about one second.

First Remote Worker

"The First Remote Worker".

For various reasons, which are described in the podcast, [Paul] Lutus was living in a cabin in the Oregon woods. Before he got the Apple II in 1976, he didn’t even have electricity -- he had to run what amounted to a 1,200 foot extension cord to a construction box that he talked the utility company into installing...

[H]is backup system was to bury floppy disks of his work in an ammo can at his cabin. He started doing that after a lightning strike reset his computer while he was working. There’s a bunch of other amusing stories as well...
