    Audeze LCD-X + Deckard

    Currently having a lot of fun with the LCD-X phones and Deckard Class A amplifier - that thing runs hot, registers 112F on the chassis, with 77F ambient temperature. Decided that it was either going to be tubes and Stax, or if SS and cheaper, then it must be Class A, and this is probably one of...

    Hexagonal boron nitride much stronger than graphene

    A two-dimensional material with similar physical properties to graphene has now turned out to blow graphene out of the water in terms of toughness. The material is called hexagonal boron nitride (h-BN), and it's so resistant to cracking that scientists are gobsmacked. The finding flies in the...

    In a first, neutrinos were caught interacting at the Large Hadron Collider

    The Large Hadron Collider’s claim to fame is its ability to unveil elusive subatomic particles. But there’s one class of particle that it had never directly detected, even though it produces them in abundance. Neutrinos, minute elementary particles, interact so little with matter that they sail...
