Photomultiplier tubes look like giant light bulbs and are used to detect light from neutrino interactions in detectors. COHERENT’s cesium iodide detector, the first to espy neutrinos at the SNS, employs a 5-inch (13-centimeter) wide photomultiplier tube. An 8-inch (20-centimeter) wide photomultiplier (shown here) is deployed in COHERENT’s nearby liquid-argon detector. Measurements from different types of detectors are necessary for comprehensive studies of neutrinos at SNS. The scientists are standing in front of the cesium-iodide-detector shielding.

After more than a year of operation at Oak Ridge National Laboratory, the COHERENT experiment, using the world’s smallest neutrino detector, has found a big fingerprint of the elusive, electrically neutral particles that interact only weakly with matter.

The research, performed at ORNL’s Spallation Neutron Source and published in the journal Science, provides compelling evidence for a neutrino interaction process predicted by theorists 43 years ago but never seen.

“The one-of-a-kind particle physics experiment at Oak Ridge National Laboratory was the first to measure coherent scattering of low-energy neutrinos off nuclei,” said ORNL physicist Jason Newby, technical coordinator and one of 11 ORNL participants in COHERENT, a collaboration of 80 researchers from 19 institutions and four nations.

The SNS produces neutrons for scientific research and also generates a high flux of neutrinos as a byproduct. Placing the detector at SNS a mere 65 feet (20 meters) from the neutrino source vastly improved the chances of interactions and allowed the researchers to decrease the detector’s weight to just 32 pounds (14.5 kilograms). In comparison, most neutrino detectors weigh thousands of tons: although they are continuously exposed to solar, terrestrial, and atmospheric neutrinos, they need to be massive because the interaction odds are more than 100 times lower than at SNS.

The scientists are the first to detect and characterize coherent elastic scattering of neutrinos off nuclei. This long-sought confirmation, predicted in the particle physics Standard Model, measures the process with enough precision to establish constraints on alternative theoretical models. [Read more…]

Oak Ridge Schools is the first district in the state to earn AdvancED STEM certification for all of its elementary and middle schools, a press release said.

AdvancED uses a research-based framework and criteria for the awareness, continuous improvement, and assessment of the quality, rigor, and substance of STEM educational programs, the press release said. STEM is an acronym for science, technology, engineering, and mathematics.

In the spring of 2016, three Oak Ridge elementary schools earned AdvancED STEM certification: Glenwood, Linden, and Woodland. These schools were the first in the district to demonstrate the capacity to prepare students for STEM fields of study and work, the press release said.

In the spring of 2017, three more schools in Oak Ridge received this distinction: Willow Brook Elementary, Jefferson Middle, and Robertsville Middle.

“Our district is the first in the state to certify every elementary and middle school in the district,” the press release said. “We are committed to preparing our learners for the careers of tomorrow by perpetuating their enthusiasm for STEM disciplines today. Our focus on STEM demonstrates our continued commitment to ensure every Oak Ridge student is prepared for college, career, and life success.” [Read more…]

Have you ever run on a treadmill until you are out of breath? Have you ever gotten to a comfortable point and then pushed that speed up just a little more to give yourself a better workout? Tennessee science teachers are on the treadmill, have pushed themselves, are seeing results, and are gearing themselves up for more.

The Nation’s Report Card was recently released showing that Tennessee students grew faster than the national average in science. Tennessee is now ranked the fastest improving in the nation in science and has moved into the top 25 states in science. Tennessee has eliminated the achievement gap between male and female students and has narrowed the achievement gap between white, Hispanic, and black students in science. This encouraging news provided us with needed results and evidence that education changes in Tennessee are having a positive outcome with our students. Teachers are seeing results of their additional work and are pushing for even higher scores in the future. [Read more…]

Environmental scientists can more efficiently detect genes required to convert mercury in the environment into more toxic methylmercury with molecular probes developed by researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory. The research could help the cleanup work at the Y-12 National Security Complex.

“We now have a quick and easy-to-use tool that we can employ in any environment to test for the presence of microorganisms capable of methylating mercury and determine how abundant they are,” said ORNL’s Geoff Christensen, a post-doc and lead author of a paper published in Applied and Environmental Microbiology.

In 2013, ORNL researchers reported in Science on the discovery of two genes known to transform inorganic mercury into its highly toxic organic form. Development of the newly validated probes further advances research to protect human health, a press release said.

For this study, researchers tested the probes against 31 strains of microorganisms for which they know the ones that produce methylmercury and scored a 94 percent confirmation rate, the press release said. This validation procedure is critical to the next step of moving the probes into the field to help determine the amount of methylmercury likely to be generated in any given environment. [Read more…]
