After a bruising 42-day shutdown, the government has finally reopened. We took a look at what's next for federal science—how quickly things will get back up to speed and whether there will be long-term consequences.

Radio detection of air-showers independent of a particle detector providing the trigger is a big step towards future observatories of cosmic rays and eventually ultra-high energy neutrinos! 🔭🧪
These atomic nuclei, which rain down from the sky with an energy a million times greater than that of particles accelerated in the LHC at CERN, were detected for the first time using radio antennas operating autonomously and systematically, deployed in the Gobi Desert in China.
The GRAND project has observed its first cosmic rays!

Prof Michele Dougherty, first woman to hold position, is upbeat about role of private sector in space exploration
The Royal Society was right to keep Elon Musk as a fellow, the UK’s new astronomer royal has said, adding that there is a benefit to the private sector playing a role in space exploration.
Speaking to the Guardian after becoming the first woman to hold the 350-year-old position, the planetary scientist Prof Michele Dougherty said she had not been involved in the meetings around Musk’s fellowship, but that she supported the academy’s stance. Continue reading...
