Going with the gut
Clostridium difficile (C. diff), Columbia University image.
The gut – a.k.a. the gastrointestinal tract that starts at the mouth and ends at the anus – contains trillions of bacterial cells. A majority are good bacteria that reside in the nearly 30 feet of the large and small intestines. These good bacteria are responsible for a person’s overall health. But sometimes a harmful bacterium called Clostridium difficile (C. diff) infects the gut.
But what if scientists could identify and isolate the bacteria in a fecal sample that inhibit C. diff and then put just those bacteria into a pill or drink? That’s exactly what my colleagues and I are working on at Los Alamos National Laboratory: pulling together bacteria into a super-powerful cocktail that washes out the infection. The work exploits the Laboratory’s extensive biological research efforts developed in support of our national security mission. (Full Story)
One step closer to understanding explosive sensitivity with molecule design
Explosives have an inherent problem – they should be perfectly safe for handling and storage but detonate reliably on demand. Using computer modeling and a novel molecule design technique, scientists at Los Alamos National Laboratory have replaced one “arm” of an explosive molecule to help unravel the first steps in the detonation process and better understand its sensitivity — how easily it begins a violent reaction.
"It started out with, can we take a common initiating explosive PentaErythritol TetraNitrate (PETN) and replace parts of it to change sensitivity properties," said explosives chemist Virginia Manner. (Full Story)

LANL scientists honored for exceptional work
Four Los Alamos National Laboratory scientists were honored at the Los Alamos Medal ceremony April 12 for their distinguished achievements that have impacted the success of the laboratory and the nation, either through mission accomplishments or enhancing the laboratory’s distinction.
This year, the Medals were awarded to Howard Menlove, who helped establish the laboratory’s technical expertise in nuclear safeguards and nonproliferation that became the foundation for international nonproliferation programs; and three members of the Human Genome Project team at Los Alamos – Scott Cram, Larry Deaven, and Robert Moyzis – who were instrumental in motivating the Department of Energy to formally initiate the Human Genome Project in 1987.

Los Alamos National Laboratory Director Terry Wallace speaks to community leaders
LANL Director Dr. Terry Wallace explained that he graduated from Los Alamos High School, got his undergraduate degrees at New Mexico Institute of Mining and Technology and was a professor “somewhere else” for 20 years, but that he always got to work with Los Alamos and knew he would get to return 16 years ago.
“We’re 75 years in but we’re at the center of some extraordinary things that are happening around the country and the world, and some of these things are some great anxiety-producing events. But we’re here to do the business of that country in terms of national security,” he said. (Full Story)

LANL wildland fire manager discusses drought
“I don’t think I’m going to surprise anybody when I tell you what the current conditions are,” Los Alamos National Laboratory Wildland Fire Manager Manny L’Esperance said Monday evening at a Science on Tap event at UnQuarked in Central Park Square.
“We’re in the midst of a drought that appears to be getting worse and I don’t know what you folks think about climate change but this drought, every year we hear it’s getting worse. We are seeing fire behavior that we have never seen before and this year’s no different,” he said. (Full Story)
