The Oak Ridge Public Works Department will close part of Tusculum Drive from 8 a.m. until 3 p.m. starting Monday, August 7, so crews can replace a culvert under the road. The culvert replacement project is expected to be active until Wednesday, August 9, a press release said.

Residents will have access to their homes and driveways during this time, but the roadway will be closed to through traffic, the press release said.

“All work is subject to change based on such unknowns as the weather,” the release said. “Residents are urged to use extreme care and caution while driving in the area. All others are advised to use alternate routes. [Read more…]

Researchers at federal sites such as Oak Ridge National Laboratory first developed many of the concepts and tools that ecologists still use today, according to the U.S. Department of Energy.

“The study of ecology is likely to evoke images of recycling signs or the ‘blue marble’ Earth from space associated with the environmental movement of the 1960s,” the U.S. Department of Energy Office of Science said in an article published online on June 28. “But in reality, ecology as a field largely developed to meet the need to monitor radioactive contamination in the Atomic Age.”

The federal government had a major knowledge gap after World War II, according to the article, which was written by Shannon Brescher Shea, senior writer/editor in DOE’s Office of Science. Specifically, the United States government needed to know more about the consequences of nuclear weapons use and production, from the effects of fallout to waste disposal.

The Atomic Energy Commission’s national laboratories were logical places to answer these questions, the article said. [Read more…]

Peace activists will have events in Oak Ridge and Knoxville starting Saturday and ending Wednesday that will recall the atomic bombings of Hiroshima and Nagasaki, Japan, during World War II, and the activists will call for a ban on nuclear weapons.

The events have been organized by the Oak Ridge Environmental Peace Alliance. OREPA has events each August remembering the bombings of Hiroshima and Nagasaki near the end of World War II. The Y-12 National Security Complex in Oak Ridge enriched uranium for the first atomic bomb used in wartime. Code-named “Little Boy,” the bomb was dropped over Hiroshima, Japan, on August 6, 1945, shortly before the end of the war.

OREPA has scheduled a Saturday event called “And We Are Saying Peace.” It will start at 12:30 p.m. with a concert and theater presentation at Alvin K. Bissell Park in Oak Ridge. Those who attend will call on the United States to join the countries that passed a legal treaty prohibiting nuclear weapons at the United Nations on July 7, a press release said.

The Saturday event will also mark the conclusion of a peace pilgrimage from Asheville, North Carolina, to Oak Ridge, led by the Buddhist order Nipponzan Myohoji, the press release said. The walk left Asheville last Sunday and is expected to arrive at Bissell Park on Saturday. The final leg will leave Solway at 9 a.m. Saturday. [Read more…]

The U.S. Navy teamed up with Oak Ridge National Laboratory to print the military’s first 3D-printed submersible hull in just four weeks. The parts were printed in just days, rather than weeks, and production costs were cut by 90 percent.

The hull was printed at ORNL’s Manufacturing Demonstration Facility in Hardin Valley through a partnership with the Navy’s Disruptive Technology Lab, according to a story published July 20 by the U.S. Department of Energy Office of Energy Efficiency and Renewable Energy. ORNL is a DOE laboratory.

“ORNL and the Navy saw this is as an opportunity to bring together their resources and expertise in a partnership with the potential to revolutionize manufacturing in the defense sector,” the DOE story said. “Not only can the Navy find new ways to reduce traditional costs associated with manufacturing, but the lessons learned from this project will help ORNL further explore 3D printing applications in the boating industry, aerospace, buildings, and anything that requires a large, resilient structure. Partnerships like these help drive economic growth and reinforce our national security.”

The team working on the 3D-printed submersible hull needed to create a 30-foot proof-of-concept hull out of carbon fiber composite material, DOE said. The prototype vessel is called the Optionally Manned Technology Demonstrator, and it could be used to deploy logistics capabilities and sensors. Future vessels will need to be manufactured faster and incorporate new designs to support Navy missions, DOE said. [Read more…]

Michael Yates of Ridgeview Behavioral Services will discuss Building Strong Brains—Tennessee’s ACEs (Adverse Childhood Experiences) Initiative on Saturday, August 5, at 10:30 a.m. It’s part of the free community mental health program series at Grace Lutheran Church in Oak Ridge. Yates’ presentation will focus on the effects of early childhood trauma on brain development, a press release said.

“Science indicates the structure of a young child’s brain is shaped by the interaction between genes and experience, and this can have a positive or negative result,” the press release said.

Science makes it clear that adverse childhood experiences can negatively impact the architecture of the developing brain, while children alternatively thrive in a safe, stable, nurturing environment of supportive families, caregivers, neighborhoods and communities, Yates said in the press release.

Oak Ridge Schools will transport students and provide eclipse glasses for the solar eclipse on Monday, August 21. It will be a once-in-a-lifetime experience for many people.

The path of totality for the solar eclipse cuts through Oak Ridge, according to information provided to the Oak Ridge Board of Education for a meeting on Monday, August 7.

Because the path of totality cuts through Oak Ridge, half of the city’s schools are in the path of totality and half are not, the information said.

“We believe that every Oak Ridge student should have the opportunity to learn about the eclipse and to experience the total eclipse,” the information said. “Therefore, we will be transporting students from the east side of Oak Ridge to the west side, with parental permission.”

The solar eclipse of 2017 is a once-in-a-lifetime experience for many people, the information said. [Read more…]

T minus 18 days. On Monday, August 21, a total solar eclipse—when the disk of the moon completely covers the sun—will be visible in the United States along a path from central Oregon through Tennessee and on to South Carolina.

In Tennessee, many points to the south and southwest of Knoxville will experience a total eclipse. Knoxville, however, will have only a 99.75 percent partial eclipse.

UT experts are providing tips on how East Tennesseans can view the eclipse safely and protect their eyes, wherever they’re viewing. You can click on any of the links below to learn more.

Oak Ridge National Laboratory on Wednesday said it is building the world’s smartest supercomputer.

The new supercomputer is called Summit. It will be located in a new data center next to Titan, which is now the fourth most powerful supercomputer in the world.

Summit will be 5-10 times faster than Titan, ORNL said. It will move data five to 10 times faster, store eight times more data, and perform many more calculations simultaneously than Titan, the lab said in information provided by spokesperson Morgan McCorkle.

Summit will be the world’s smartest supercomputer because of its enormous memory and data handling capabilities as well as its unique machine learning processor design, McCorkle said.

“The first of Summit’s cabinets arrived Monday, and our team is in the process of uncrating and putting them in place,” McCorkle said in response to questions from Oak Ridge Today. [Read more…]
