Tropical forests play a major role in the planet’s carbon cycle, but there are large uncertainties over how they will respond over the next 100 years as the planet’s climate warms.
An expansive new project called Next Generation Ecosystem Experiments-Tropics, or NGEE-Tropics, aims to bring the future of tropical forests into much clearer focus.
“Los Alamos National Laboratory scientists are playing a major role in the project, specifically in relation to quantifying, understanding, and modeling drought impacts on tropical forests, and improving the next-generation of models” said scientist Nate McDowell, project leader of the Los Alamos components.
The project’s goal is the development of a model that represents how tropical forests interact with Earth’s climate in much greater ecological detail than ever before. This will help scientists explore, more accurately than is possible today, how rising temperatures, shifting precipitation patterns, increasing greenhouse gas levels and other natural and human-induced changes affect tropical forests’ influence on Earth’s climate.
Scientists know less about the flux of carbon, water and energy between tropical forests and the atmosphere than about most other biomes. These processes are also poorly represented in climate models.
Craig Martin to discuss county Open Space plan
Craig Martin will give a talk about his plan for the Los Alamos Open Space System, a plan he’s been working on for 15 years. The talk is scheduled for 7 p.m. Jan. 14 at the Pajarito Environmental Education Center on Orange St.
The purpose of the plan is to identify the key features of county open space that make Los Alamos a desirable place to live and visit, and to outline ways to protect those important resources. The features identified by the plan are vistas and viewpoints, natural resources, cultural and historical resources, the Los Alamos County Trail Network and open space as trail corridors and “Neighborhood open space.”
The work on this plan began in the late 1990s when the county established two open space planning committees. Martin’s plan relies heavily on the work of those committees, which represents about four years of work.
ALBUQUERQUE, N.M. (AP) — New Mexico on Saturday levied more than $54 million in penalties against the U.S. Department of Energy for numerous violations that resulted in the indefinite closure of the nation's only underground nuclear waste repository.
The state Environment Department delivered a pair of compliance orders to Energy Secretary Ernest Moniz, marking the state's largest penalty ever imposed on the agency. Together, the orders outline more than 30 state permit violations at the Waste Isolation Pilot Plant in southeastern New Mexico and at Los Alamos National Laboratory.
The orders and the civil penalties that come with them are just the beginning of possible financial sanctions the Energy Department could face in New Mexico. The state says it's continuing to investigate and more fines are possible.
Los Alamos National Laboratory director Charlie McMillan denounced a published report earlier this week that exposed missteps at the lab that played a part in a radiation leak at the nation’s only underground nuclear waste repository.
In an internal memo to staff, obtained by the Los Alamos Monitor, McMillan dismissed suggestions that the lab was withholding scientific theories about the Feb. 14 accident at the Waste Isolation Pilot Plant.
“I want to assure you that nothing is further from the truth, and scientific integrity is valued above all else at this institution,” he said in the memo.
Following up on a joint CEO proclamation on STEM education, Los Alamos National Laboratory, Sandia National Laboratories and several partners are hosting a discussion on “STEM Education in New Mexico” at 10 a.m. Saturday at Highland High School in Albuquerque.
Laboratory Director Charlie McMillan, Sandia National Laboratories Director Paul Hommert, and other CEOs of top employers in the state, including the Air Force Research Laboratory, Intel, PNM Resources and Northrop Grumman, signed a proclamation that recognizes the importance of the STEM fields in New Mexico and commits Los Alamos and its STEM partners to lead the way in sparking math and scientific inspiration in New Mexico residents and engage students in hands-on, minds-on STEM activities.
“Through this partnership, we continue to inspire and cultivate the curiosity of students as they consider STEM as a career option,” said Kurt Steinhaus, Los Alamos’ Community Programs Office Director. “This discussion — and a proclamation signed by the partners — emphasizes the importance of working together as we ‘grow our own’ and help meet workforce needs in New Mexico.”
By looking at the dark spaces between visible galaxies and stars the NASA/JPL CIBER sounding rocket experiment has produced data that could redefine what constitutes a galaxy.
“What was very surprising is the brightness of many fluctuations that appear between stars and galaxies,” said Los Alamos scientist Joseph Smidt, part of the data analysis team that studied the data from CIBER. “These fluctuations are having us rethink what goes on between stars and galaxies. The data suggests that galaxies shed many more of their stars into the intervening space than was originally thought.”
Results from two of four CIBER flights, launched from White Sands Missile Range in New Mexico in 2010 and 2012, appear in today’s issue of the journal Science.
A report issued Wednesday by the inspector general of the U.S. Department of Energy squarely places blame for the shutdown of the nation's only underground nuclear waste repository on failures at Los Alamos National Laboratory.
The inspector general's office identified several major weaknesses in the lab's procedures for packing contaminated gloves, tools and other radiological wastes that were destined for permanent storage at the Waste Isolation Pilot Plant in southern New Mexico.
Not all of the lab's procedures were properly vetted and some procedures didn't conform with environmental requirements, according to the findings.
The report reinforces the findings of internal reviews done by the lab and the Energy Department following a Feb. 14 release of radiation from a barrel of waste that came from Los Alamos. The release contaminated 22 workers and forced the indefinite closure of the nuclear waste repository.
"Our review identified several major deficiencies in LANL's procedures for the development and approval of waste packaging and remediation techniques that may have contributed to the radiological event," the inspector general said.
Today, the Department of Energy (DOE) released the Waste Isolation Pilot Plant (WIPP) Recovery Plan, outlining the necessary steps to resume operations at the transuranic waste disposal site outside of Carlsbad, N.M. WIPP operations were suspended following an underground truck fire and a radiological release earlier this year.
Recent news reports have incorrectly suggested that there is a second breached drum in the Waste Isolation Pilot Plant (WIPP) underground facility.
According to a WIPP press release, there is no evidence to suggest a release from a second drum. The site conducted initial surveys that showed no evidence of a radiological release from Panel 6, and we have seen no evidence since then that suggests anything different.
“Worker safety is the Department’s highest priority and workers entering radiologically controlled areas of the WIPP underground facility are trained and equipped with state of the art protective equipment. Safety measures are being taken to protect all workers during every entry into the underground facility,” the press release stated.
Los Alamos National Laboratory achieved its lowest radioactive air emissions rate in 20 years in 2013, according to annual air quality results released recently.
According to a lab press release, each year, the laboratory measures air emissions through a comprehensive system of 40 air monitoring stations located at the laboratory and in neighboring communities that provide data about ambient air quality. The laboratory monitors 80 minor sources and 29 major sources at the laboratory, such as exhaust stacks from radiological and nuclear facilities.
In 2013, the Los Alamos offsite dose rate was 0.21 millirem, about 2 percent of the Environmental Protection Agency’s Clean Air Act limit of 10 millirem. This 20-year low is attributed to focused, more efficient operations and the cleanup of legacy environmental sites.

Challenges are a part of life. Some challenges are tougher than others, but it is up to the individual to overcome.
Christa Brelsford, 29, knows what it is like to encounter obstacles and do whatever it takes to prevail.
The Los Alamos resident will be competing in the International Federation of Sports Climbing competitions in Gijón, Spain. She left on Saturday for the week and a half long event.
She will be a contender in the Women Lower Amputee Division in Paraclimbing.
The event is for disabled people who are rock climbers and want to continue to do so after injury.
Like a protective tent over a colony of harmful bacteria, biofilms make the treatment of skin infections especially difficult. Microorganisms protected in a biofilm pose a significant health risk due to their antibiotic resistance and recalcitrance to treatment, and biofilm-protected bacteria account for some 80 percent of total bacterial infections in humans and are 50 to 1,000 times more resistant to antibiotics than simpler bacterial infections.
“In essence, we may have stumbled onto a magic bullet,” said David Fox, a Los Alamos National Laboratory researcher on the project. “Through a robust screening strategy, our research team has identified a unique class of materials, known as ionic liquids, which both neutralize biofilm-forming pathogens and deliver drugs through the skin,” he said.
The Justice Department today announced that a former contract employee at the Los Alamos National Laboratory (LANL) was sentenced this morning for conspiring to violate the Atomic Energy Act by communicating classified nuclear weapons data to a person believed to be a Venezuelan government official, and making false statements to the FBI.
Marjorie Roxby Mascheroni, 71, of Los Alamos, was sentenced by U.S. District Judge William P. Johnson to a year and a day in federal prison followed by three years of supervised release based on a guilty plea entered in June 2013. Her husband, Pedro Leonardo Mascheroni, 79, a naturalized U.S. citizen from Argentina who is also a former LANL employee, also entered a guilty plea in June 2013, and is in federal custody pending his sentencing hearing.
The Department of Energy’s Environmental Projects Office will take down the water
tower at the west end of Technical Area 21 (TA-21) today beginning at about noon.
The tower to the east is scheduled to come down tomorrow.
The Lakeworth Group LLC of Los Alamos will perform the demolition. Lakeworth is
designated through the U.S. Small Business Administration as an 8(a) and
Economically Disadvantaged Women-Owned Small Business. The contract is valued at
Demolition of the towers, one of them 66 years old and the other 38 years old, is
one of several projects to remove remaining structures at TA-21.
“By bringing down these towers, we are making a noticeable difference in the skyline
at TA-21,” said Pete Maggiore, Assistant Manager for Environmental Programs at the
Los Alamos Field Office. “This is another positive step toward eventual transfer of
this property to Los Alamos County.”
Technical Area 21 was one of the early sites of the Manhattan Project and Cold
War-era work at Los Alamos National Laboratory (LANL). It was the location of the
world’s first plutonium processing facility and where groundbreaking tritium
research took place.
