ETHEREAL quantum entanglement has been captured in solid crystals, showing that it is more robust than once assumed. These entanglement traps could make quantum computing and communication more practical.

How I got interested in shortwave and ham radio by building a crystal radio kit as a child.

"Researchers at MIT and elsewhere have succeeded in creating a synthetic crystal that can very effectively control the transmission of heat -- stopping it in its tracks and reflecting it back. This advance could lead to insulating materials that could block the escape of heat more effectively than any present insulator."

"Hudnall: I really do believe that repression makes you sick. I'm big believer of what is coming out in the neuroscience and therapy community. Brene Brown, who is a shame and guilt expert, said it best: "We have an epidemic of shame in this country." If you keep things inside and have no one to talk to - and this is not crystals and patchouli - you will get sick, you will be miserable, you will ruin your relationships, and you will be unhappy. I know people whose lives were ruined by silence. Especially women. The one thing that has really opened my eyes while teaching is just what we do to our women. Only my women students have said to me, "I don't know if I have anything worth saying." It smacks me in the face every day. We are really fucking up our women"
