Faults are “grungy, messy features and they don’t behave as we would like them to”, explains Ross Stein, who heads a seismic-risk-assessment company. None of the warning signs that once held promise - isotopes in water, tiny pre-quakes, electromagnetic signals and even odd animal behaviour - has stood up to testing. Decades of research have shown that it’s probably impossible to predict when a geological fault will start to shake. Geologists knew decades ago that a large quake would strike Turkey and Syria, the question was when.

Researchers tested the algorithm on a three-square-kilometre area of Chile’s Atacama Desert, where it reduced their search area by up to 97% and increased their likelihood of finding endoliths, a type of rock-dwelling, photosynthetic organism, by up to 88%.

She describes an as-yet-unveiled plan to pour €7 billion (US$7.4 billion) into health innovation and more funding into ‘risky research’, and how she will find ways to simplify scientists’ lives to allow them to have more time to devote to their work. “My objective is evolution, not revolution,” says Retailleau, who trained as a physicist and took office last May. Nature | 4 min read French minister plans science shake upįrance’s minister of higher education and research, Sylvie Retailleau, speaks to Nature about her ambitions for science in France, in her first interview published in English since taking up the post. “It is not really easy to move a spacecraft from one launcher to another,” says Euclid mission manager Giuseppe Racca, “but we managed.” The Euclid space telescope had to be reassigned to lift off from Cape Canaveral, Florida, instead of ESA’s spaceport in French Guyana. Fifteen flights are now waiting for Vega C and the smaller Vega, which are both grounded until at least later this year. Two satellites were lost in the incident, caused by a faulty nozzle produced in Ukraine. The Vega C rocket’s launch failure in December could exacerbate the backlog of European Space Agency (ESA) missions.
