Armored with plastic 'hair' and silica, new perovskite nanocrystals show more durability

Researchers at the Georgia Institute of Technology have demonstrated a novel approach aimed at addressing the perovskite's durability problem: encasing the perovskite inside a double-layer protection system made from plastic and silica.

You know the trope "nothing created is original anymore" since we have essentially used up all of the possible formulas for TV/Film/Music/Literature… do you think this will apply when we meet an alien race? As in, we will share common themes and even sounds in TV/Film/Music/Literature as well?

have had this thought in my head for awhile now… was very curious. It has to be possible that we will at least share some musical genre sounds or classical character archetypes in novels or shows right?

Boris Johnson Bets on a Strategy Theresa May Ignored

The Conservative Party did not lose Britain's 2017 general election, but it has spent the last two and a half years trying to understand why it did. The Labour Party, in contrast, did lose the 2017 election but has acted as if it did not, convinced that its only mistake was not doing enough of what had worked the time before.
