That's right, that's a security conference, and those are babies in attendance.
350 women, thirty speakers, and thirty concurrently-running workshops, in three full days.

I am happy to announce, that I will present some of my year-long robot security and privacy research next week @defcon 31 in Las Vegas. Join me in my Demo Lab on Fri and my talk "Vacuum robot security and privacy - prevent your robot from sucking your data" on Sun. #DEFCON #IoT

First claimed successful replication of LK-99

Accomplished by a team at the Huazhong University of Science and Technology and posted 30 minutes ago.

Why this is evidence:
The LK-99 flake slightly levitates for both orientations of the magnetic field, meaning it is not simply a magnetized piece of iron or similar 'magnetic material'. A simple magnetic flake would be attracted to one polarity of the strong magnet, and repelled by the other. A diamagnet would be repelled under either orientation, since it resists and expels all fields regardless of the polarity.

Caveats
There is no way to verify the orientation of the strong magnet in this video, also, there are yet to be published experimental measured values of this sample. Diamagnetism is a property of superconductors but without measured and verified data, this is just suggestive of a result.

Take-away
If this synthesis was indeed successful, then this material is easy enough to be made by labs other than the original research team. I would watch carefully for results out of Argonne National Lab, who are reported to be working on their own synthesis of a sample.

This overall corroborates two independent simulation studies that investigated the original Korean authors claim about material and crystal structure, and both studies supported the claims.

The attached video shows a small flake of their sample responding to an external magnetic field. I scroll through the video to skip to the relevant part.

This invasive Bluetooth car battery monitor was found to be sending the following location data to 🇨🇳

- GPS
- Wifi devices
- Cell phone towers

The Apple and Google app stores said no personal data was collected.

A new update has emerged. Let's see what was changed 👇(1/n)
