The annual Department of Energy evaluation shows Fermilab’s leadership and safety grades rose from C+ to B in 2025, yet finance‑system gaps and transformer shortages caused concern. Argonne posted ...

MicroBooNE's results show no evidence for sterile neutrinos, strengthening support for the standard three-flavor neutrino model and adding complexity to earlier unexplained anomalies.

Scientists at Fermilab’s MicroBooNE experiment have ruled out the existence of the elusive sterile neutrino, a particle proposed for decades to explain puzzling neutrino behavior. Their high-precision ...

For three decades, a riddle has followed neutrinos, the near-weightless particles that stream through Earth by the trillions each second. They change identities as they fly, shifting among three known ...

Holtkamp will oversee the completion of the $1.5bn Long-Baseline Neutrino Facility-Deep Underground Neutrino Experiment ...

To explain these observations, they proposed a new kind of energy that is responsible for driving the universe’s accelerated expansion: dark energy. Astrophysicists now believe dark energy makes up ...

Since the 1990s, physicists have pondered the tantalizing possibility of an exotic fourth type of neutrino, dubbed the “sterile” neutrino, that doesn’t interact with regular matter at all, apart from ...

Experimental particle physicists working at the MicroBooNE experiment at Fermilab National Accelerator Laboratory have found evidence against the existence of a "sterile" type of neutrino hypothesized ...

Fermi National Accelerator Laboratory has a new director. Norbert Holtkamp will take over Jan. 12, the University of Chicago announced Monday. Holtkamp is the former deputy director of the SLAC ...
