UrduThe international KArlsruhe TRItium Neutrino (KATRIN) experiment in Germany recently reported a new upper limit on the mass of the neutrino. This limit—0.8 electronvolts (eV)—is the lowerst scientists have achieved. As the results are confirmed and refined, they will help scientists better understand the neutrino and its role in the evolution of the universe.

Brookhaven Chemist Minfang Yeh Wins 2021 DPF Instrumentation Award
UPTON, NY—Minfang Yeh, a senior scientist at the U.S. Department of Energy’s Brookhaven National Laboratory, has won the American Physical Society’s 2021 Division of Particles and Fields (DPF) Instrumentation Award. The award honors Yeh’s pioneering work in the development and production of high-performance water-based liquid scintillators for particle physics experiments, including metal loaded scintillators for rare process experiments.
Scientists Spot Rare Neutrino Signal for Big Physics Finding
Scientists at Brookhaven National Laboratory developed a software toolkit that reconstructs and isolates neutrino data in 3D. This software directly enabled the long-awaited findings from the MicroBooNE experiment released today by Fermilab in four complementary analyses. The Wire-Cell team at Brookhaven Lab led one of the four analyses—the most sensitive analysis of the electron-neutrino interaction. Some components of the Wire-Cell toolkit were also used in the other three analyses.
Gamma rays and neutrinos from mellow supermassive black holes
The Universe is filled with energetic particles, such as X rays, gamma rays, and neutrinos. However, most of the high-energy cosmic particles’ origins remain unexplained.

New Brunswick, N.J. (April 21, 2021) – Rutgers University–New Brunswick astrophysicist John P. (Jack) Hughes is available for interviews on a supernova (exploding star) discovery published today in the journal Nature. The discovery, made with NASA’s Chandra X-ray Observatory, features…
Lena Funcke Receives Leona Woods Lectureship Award
Lena Funcke, a theoretical physicist who conducts research at the intersection of fundamental particles, the cosmos, and quantum computing, has been named a recipient of the Leona Woods Distinguished Postdoctoral Lectureship Award by the Physics Department at the U.S. Department of Energy’s Brookhaven National Laboratory.
Patrick Huber: Then and Now / 2010 Early Career Award Winner
Professor Patrick Huber is the director of Virginia Tech’s Center for Neutrino Physics. His research develops and advances theoretical tools to analyze data from neutrino experiments, the results of which will improve our understanding of neutrinos’ properties and their role in the cosmos.
Righting a wrong, nuclear physicists improve precision of neutrino studies
Led by the Department of Energy’s Oak Ridge National Laboratory, a new study clears up a discrepancy regarding the biggest contributor of unwanted background signals in specialized detectors of neutrinos.
Scientists Say Farewell to Daya Bay Site, Proceed with Final Data Analysis
The Daya Bay Reactor Neutrino Experiment collaboration – which made a precise measurement of an important neutrino property eight years ago, setting the stage for a new round of experiments and discoveries about these hard-to-study particles – has finished taking data. Though the experiment is formally shutting down, the collaboration will continue to analyze its complete dataset to improve upon the precision of findings based on earlier measurements.
90 Years of Neutrino Science
Berkeley Lab has a long history of participating in neutrino experiments and discoveries in locations ranging from a site 1.3 miles deep at a nickel mine in Ontario, Canada, to an underground research site near a nuclear power complex northeast of Hong Kong, and a neutrino observatory buried in ice near the South Pole.
Researchers validate theory that neutrinos shape the universe
The effect that nearly massless, subatomic particles called neutrinos have on the formation of galaxies has long been a cosmological mystery — one that physicists have sought to measure since discovering the particles in 1956.But an international research team has created cosmological simulations that accurately depict the role of neutrinos in the evolution of the universe in a study recently published in The Astrophysical Journal.
Q&A: How machine learning helps scientists hunt for particles, wrangle floppy proteins and speed discovery
At the Department of Energy’s SLAC National Accelerator Laboratory, machine learning is opening new avenues to advance the lab’s unique scientific facilities and research.
New NSF Physics Frontier Center Will Focus on Neutron Star Modeling in ‘Gravitational Wave Era’
A new Physics Frontier Center at UC Berkeley, supported by the National Science Foundation, expands the reach and depth of existing capabilities on campus and at neighboring Berkeley Lab in modeling one of the most violent events in the universe: the merger of neutron stars and its explosive aftermath.
Scientists Successfully Demonstrate a New Experiment in the Search for Theorized ‘Neutrinoless’ Process
Nuclear physicists affiliated with Berkeley Lab played a leading role in analyzing data for a demonstration experiment in France that has achieved record precision for a specialized detector material.
Virginia Tech research provides new explanation for neutrino anomalies in Antarctica
A new research paper co-authored by a Virginia Tech assistant professor of physics provides a new explanation for two recent strange events that occurred in Antarctica – high-energy neutrinos appearing to come up out of the Earth on their own accord and head skyward.
Daya Bay Reactor Experiment Continues to Generate Data
Largely unaffected by the pandemic, the Daya Bay reactor neutrino experiment in Shenzen, China, has continued to pump data to remote supercomputers for analyses.
CUORE Underground Experiment in Italy Carries on Despite Pandemic
As the COVID-19 outbreak took hold in Italy, researchers working on a nuclear physics experiment called CUORE at an underground laboratory in central Italy scrambled to keep the ultrasensitive experiment running and launch new tools and rules for remote operations.
Researchers home in on extremely rare nuclear process
A hypothetical nuclear process known as neutrinoless double beta decay ought to be among the least likely events in the universe. Now the international EXO-200 collaboration, which includes researchers from the Department of Energy’s SLAC National Accelerator Laboratory, has determined just how unlikely it is: In a given volume of a certain xenon isotope, it would take more than 35 trillion trillion years for half of its nuclei to decay through this process – an eternity compared to the age of the universe, which is “only” 13 billion years old.
