Danny McKnight’s U.S Army Rangers’ unit was the focus of the movie “Black Hawk Down”—the story of a battle that occurred in Somalia 20 years ago.

McKnight told an audience at Oak Ridge National Laboratory on Monday, Veterans Day, that he visits the six graves of men who lost their lives in that battle every five years as he did this past October.

“It reminds me of how special they were and still are to me,” said McKnight, a 28.5-year veteran of the Rangers and author of the book “Streets of Mogidishu—Leadership at Its Best” that recounts the battle of Oct. 3-4, 1993. “I want people to know about it because I want people to understand that’s what we need to do. I never want to forget them. I don’t care if they’ve been gone 50 years. As long as I can walk, talk and breathe every five years, they’ll see me. I know they see me.”

Three hundred people recently attended the unit’s first reunion in 20 years in October when they met in Dallas. [Read more…]

Researchers studying more effective ways to convert woody plant matter into biofuels at Oak Ridge National Laboratory have identified fundamental forces that change plant structures during pretreatment processes used in the production of bioenergy.

The research team, which published its results in Green Chemistry, set out to decipher the inner workings of plant cell walls during pretreatment, the most expensive stage of biofuel production. Pretreatment subjects plant material to extremely high temperature and pressure to break apart the protective gel of lignin and hemicellulose that surrounds sugary cellulose fibers. [Read more…]

Knoxville Regional LEGO Tournament

About 100 students representing 18 Knoxville area teams will compete in a regional LEGO tournament Saturday at Hardin Valley Academy, working with miniature robots that perform required tasks on a table.

Robertsville Middle School is the defending state champion. Under the new format this year, the team needs to qualify in this regional tournament before advancing to the state tournament.

“This year’s theme in ‘Nature’s Fury,’” said John Tilson, a Hardin Valley science teacher and Saturday’s tournament director. “The students have a lot of problems they need to solve. They design and build a predominantly LEGO robot. They perform a certain number of challenges and they get points for each challenge. They have to do certain rescues, and they have to move certain items from place to place.” [Read more…]

A citizens’ panel will discuss a strategy document tonight that outlines possible solutions for managing contaminated groundwater on the federal reservation in Oak Ridge.

It’s the focus of a 6 p.m. meeting of the Oak Ridge Site Specific Advisory Board. The strategy document was developed to address problems with contaminated groundwater on the U.S. Department of Energy’s Oak Ridge Reservation.

The meeting is in the DOE Information Center in the Office of Science and Technical Information on Oak Ridge Turnpike. The public is welcome to attend. OSTI is between Science.gov Way and Melton Lake Drive. [Read more…]

The Association of Marketing and Communication announced last week that Oak Ridge National Laboratory won eight platinum and six gold awards in its annual international competition.

The competition recognizes “outstanding creative achievement by marketing and communication professionals” and drew more than 6,500 entries, according to a MarCom release.

“Our designers, writers, and editors take great care in explaining and promoting ORNL’s contributions to scientific discovery, clean energy, and national security,” said David Keim, ORNL’s director of communications. “We hope this recognition draws more attention to the significant science our researchers and partners are conducting at ORNL.” [Read more…]

Oak Ridge National Laboratory received one of eight GreenGov Presidential Awards announced Tuesday.

The lab won in the Good Neighbor category for a project titled “ORNL Good, Green, Sustainable Neighbor,” a press release said.

The fourth annual awards were announced by the White House Council on Environmental Quality. They honor federal civilian and military personnel as well as agency teams, facilities, and programs that have taken innovative steps to reduce energy use and carbon pollution, curb waste, and save taxpayer money in federal agency operations, the release said.

At a White House ceremony in Washington, D.C., senior administration officials recognized the eight award winners for exemplifying President Barack Obama’s charge to “lead by example and demonstrating extraordinary achievement in the pursuit of the president’s 2009 executive order on federal leadership in environmental, energy, and economic performance,” the release said.

KNOXVILLE—Imagine going to the doctor and the doctor peering into your genetic code to determine the best medicine to treat what ails you.

The University of Tennessee in Knoxville has received funding from computer chip maker Intel to develop computer codes to make personalized medicine like this and other transformative scientific discoveries possible.

The funding will open an Intel Parallel Computing Center at the Joint Institute for Computational Sciences, or JICS, at UT and Oak Ridge National Laboratory. Parallel computing, used in supercomputers, is a form of computation in which many calculations are carried out simultaneously. The focus of the center will be to take supercomputing to the next level to meet scientific computing demands. Today’s research faces limitations due to the amount of data, time, and energy it takes to run calculations. [Read more…]

Sen. Lamar Alexander spoke on the floor of the U.S. Senate on Wednesday in honor of nuclear weapons program workers. Among those he honored were Bill Wilcox and the Calutron Girls.

Wilcox was a Manhattan Project veteran, former technical director at the K-25 site and Y-12 National Security Complex, and Oak Ridge city historian.

Wednesday was the fifth annual National Day of Remembrance for nuclear weapons program workers. It had been recognized under a resolution that Alexander cosponsored earlier this year.

Here are the senator’s full remarks: [Read more…]

Budget cuts cause concern in research community, including at ORNL

The budget deal that Congress approved earlier this month to reopen the government and raise the debt ceiling kept in place automatic budget cuts known as sequestration.

But those across-the-board cuts are causing concern in the scientific community, including at Oak Ridge National Laboratory.

In August, ORNL Director Thom Mason said the lab had been, up to that point, mostly immune from the cuts because of steps that UT-Battelle, the managing and operating contractor, had already taken to cut costs, including through workforce restructuring, reduced staff and overhead budgets, and benefit changes.

“We’ve just been doing everything we can to prepare for lean budgets,” Mason said. [Read more…]

Gas and oil deposits in shale have no place to hide from an Oak Ridge National Laboratory technique that provides an inside look at pores and reveals structural information potentially vital to the nation’s energy needs.

The research by scientists at the U.S. Department of Energy laboratory could clear the path to the more efficient extraction of gas and oil from shale, environmentally benign and efficient energy production from coal, and perhaps viable carbon dioxide sequestration technologies, according to Yuri Melnichenko, an instrument scientist at ORNL’s High Flux Isotope Reactor.
