What Can Jellyfish Teach Us About Fluid Dynamics?

The jellyfish that move through the seas by gently pulsing their saclike bodies may not seem to hold many secrets that would interest human engineers. But simple as the creatures are, jellyfish are masterful at harnessing and controlling the flow of the water around them, sometimes with surprising efficiency. As such, they embody sophisticated solutions… Continue reading What Can Jellyfish Teach Us About Fluid Dynamics?

A New Map of the Universe, Painted With Cosmic Neutrinos

Probing Fundamental Physics Neutrinos offer rare clues that a more complete theory of particles must supersede the 50-year-old set of equations known as the Standard Model. This model describes elementary particles and forces with near-perfect precision, but it errs when it comes to neutrinos: It predicts that the neutral particles are massless, but they aren’t… Continue reading A New Map of the Universe, Painted With Cosmic Neutrinos
