Tamke-Allan Observatory at Roane State Community College continues its Summer Public Stargazing with an examination of light and light pollution on Saturday, August 3.

The gates open at 7:30 p.m. Saturday, and a public lecture will be presented at 8 p.m. by guest lecturer and retired clinical researcher Linda Fippin.

“For the vast majority of human history, nighttime lighting was limited to the hearth fire,” a press release said. “As villages, towns, and eventually cities developed, lighting was still limited to oil lamps and candles. Gas lighting was not invented until the late 18th century, and electric street lights have only been in use for about 140 years. Nighttime lighting has many benefits, but excessive and inappropriate use has led to light pollution, which not only has negative effects on people, quality of life, and the natural environment, but also wastes energy resources. This talk will cover a brief history of nighttime lighting, the effects of light pollution, and what can be done to lessen them.”

You can learn about water quality and microplastics in the Tennessee River during a meeting in Oak Ridge tonight (Thursday, June 6).

The program is scheduled to start at 7 p.m. Thursday at the University of Tennessee Arboretum Auditorium. It’s a free program offered by the UT Arboretum Society and co-sponsored by Tennessee Citizens for Wilderness Planning. No registration is required.

Microplastics have been in the news recently, a press release said. Martin Knoll, a professor of geology and hydrology at Sewanee: The University of the South, will explain why microplastics are an issue, and he will present his findings on the water quality of the Tennessee River during the program this evening.

As project manager for the Tenneswim in 2016, Knoll directed the most detailed analysis of Tennessee River water quality ever conducted, the press release said. During this project, Knoll and his colleagues found the highest levels of microplastics recorded in any river of the world to date.

Could we have a major earthquake in East Tennessee? Do we live in an active seismic zone?

These and other questions will be addressed by Robert Hatcher, University of Tennessee distinguished scientist emeritus, in a lecture, “Living with East Tennessee Geology and Earthquakes,” in Oak Ridge in April.

The lecture is scheduled from 7 to 8 p.m. Thursday, April 11, in the University of Tennessee Arboretum Auditorium at 901 South Illinois Avenue in Oak Ridge.

Hatcher was a faculty member for 32 years in the Department of Earth and Planetary Sciences and Science Alliance Center of Excellence at the University of Tennessee, a press release said.

The National Oceanic and Atmospheric Administration building in Oak Ridge is closed due to the partial shutdown of the federal government, which is now three weeks old and approaching a record length.

NOAA is part of the U.S. Department of Commerce, which is one of nine cabinet-level departments affected by the partial government shutdown. The shutdown, which mostly hinges on a dispute between President Donald Trump and Democrats in Congress over whether to allocate $5.7 billion in funding for a wall on the border with Mexico, also affects the Environmental Protection Agency, Food and Drug Administration, National Aeronautics and Space Administration, the federal judiciary, and other related government programs.

About 380,000 workers were to be sent home and not be paid for their time off during the shutdown, the New York Times reported. Another 420,000 deemed too essential to be furloughed are being forced to work without pay, the newspaper said. After past shutdowns, such workers have been reimbursed later.

It wasn’t immediately clear Friday afternoon how many NOAA workers in Oak Ridge, part of an air research laboratory that has a division here, have been furloughed and how many, if any, are being forced to work without pay. A sign posted on the front door announced that the building is closed due to the shutdown. [Read more…]

Map: How common are earthquakes in the area?

The recent 4.4 magnitude earthquake near Decatur that was felt in Oak Ridge, and other reported earthquakes since then, made us wonder: How common are earthquakes in the area?

Minor earthquakes, those that can’t be felt, are fairly common, according to a customized search of data available through the U.S. Geological Survey.

There were 247 earthquakes in a roughly three-year period in an area outlined by a custom-drawn map that includes much of East Tennessee and part of western North Carolina.

But with one exception, all of the earthquakes were 3.0 magnitude or less. Earthquakes that weak are generally not felt. [Read more…]

Seven researchers from the U.S. Department of Energy’s Oak Ridge National Laboratory have been chosen by the Innovative and Novel Computational Impact on Theory and Experiment, also known as INCITE, program to lead scientific investigations that require the nation’s most powerful computers, a press release said.

INCITE awards computing time via a proposal process to researchers seeking to harness the power of DOE computing systems at the Argonne and Oak Ridge Leadership Computing Facilities to solve some of the world’s greatest scientific challenges, the press release said.

Since INCITE’s inception in 2004, the ALCF and OLCF have continuously undergone significant upgrades to retain their edge in facilitating the most computationally demanding scientific projects. The ALCF’s most recent machine is Theta, an 11.69-petaflop Cray XC40 system whose 280,000-plus cores make it ideal for research at the nexus of simulation, data science, and machine learning. An even more powerful system, the exascale Aurora, is planned for deployment in 2021 and is projected to be capable of a quintillion (one billion billion) calculations per second. [Read more…]

Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory have received six R&D 100 Awards in recognition of their significant advancements in science and technology, a press release said. The honorees were recognized over the weekend at the 56th annual R&D 100 Conference, which is sponsored by R&D Magazine.

The awards, known as the “Oscars of Invention,” honor research and development pioneers and their revolutionary breakthroughs in materials science, biomedicine, consumer products, and more from academia, industry, and government-sponsored research agencies, the press release said. This year’s six honors bring ORNL’s total of R&D 100 awards to 216 since their inception in 1963.

ORNL researchers were recognized for the following innovations: [Read more…]
