Previously unknown aerodynamic interactions shed light on how birds fly in such a coordinated and seemingly effortless fashion.

<p>How do birds fly in a coordinated and seemingly effortless fashion?&nbsp;Part of the answer lies in precise, and previously unknown, aerodynamic interactions, reports a team of mathematicians in a newly published study. Its breakthrough broadens our understanding of wildlife, including fish, who move in schools, and could have applications in transportation and energy.</p>

Half a century ago, a series of tiny tracks in a bubble chamber at CERN changed the course of particle physics. The observation of “weak neutral currents”, announced on 19 July 1973 by Paul Musset of the Gargamelle collaboration, suggested that the electromagnetic and weak forces are facets of a more fundamental electroweak interaction that ruled in the early Universe. Exploring this new sector of nature has been a core business of CERN ever since, leading to the discovery of the W and Z bosons in 1983 and culminating with the discovery of the Higgs boson in 2012. The weak force is one of ...

The backstory and legacy of the Gargamelle collaboration’s epochal discovery of neutral currents 50 years ago.
