[:es]Maintaining perfect stability through negative feedback is a basic element of electrical circuitry, but it’s been a mystery how cells could do it — until now.[:]

[:es]A giant star’s death throes may offer the first evidence of a pair-instability supernova, and a glimpse of the first stars in the universe. [:]

[:es]A new measurement appears to have eliminated an anomaly that had captivated physicists for nearly a decade. [:]

[:es]Craig Callender worries that the analogy between black holes and thermodynamics has been stretched too far. [:]

[:es]Modern humans and more ancient hominins interbred many times throughout Eurasia and Africa, and the genetic flow went both ways.[:]

[:es]The twisting loops of the sun’s magnetic field control the flow of charged particles throughout the solar system. For the first time, researchers have created a scale model of this […]

[:es]Three experiments have vetted quantum Darwinism, a theory that explains how quantum possibilities can give rise to objective, classical reality.[:]

[:es]The discovery that apparently dead cells can sometimes resurrect themselves has researchers exploring how far they can push the point of no return.[:]

[:es]Consciousness is a famously hard problem, so Hod Lipson is starting from the basics: with self-aware robots that can help us understand how we think.[:]
