GENEVA (AP) — Top minds at the world’s largest atom smasher have released a blueprint for a much bigger successor that could vastly improve research into the remaining enigmas of physics.

The plans for the Future Circular Collider — a nearly 91-kilometer (56.5-mile) loop along the French-Swiss border and below Lake Geneva — published late Monday put the finishing details on a project roughly a decade in the making at CERN, the European Organization for Nuclear Research.

The FCC would carry out high-precision experiments in the mid-2040s to study “known physics” in greater detail, then enter a second phase — planned for 2070 — that would conduct high-energy collisions of protons and heavy ions that would “open the door to the unknown,” said Giorgio Chiarelli, a research director at Italy’s National Institute of Nuclear Physics.

A new study finds that sex and environment, not just age, strongly influence hearing sensitivity in diverse human populations.

The massive changes in US research brought about by the new administration of President Donald Trump are causing many scientists in the country to rethink their lives and careers. More than 1,200 scientists who responded to a Nature poll — three-quarters of the total respondents — are considering leaving the United States following the disruptions prompted by Trump. Europe and Canada were among the top choices for relocation.

The trend was particularly pronounced among early-career researchers. Of the 690 postgraduate researchers who responded, 548 were considering leaving; 255 of 340 PhD students said the same.
