President Obama nominates ASU professor to key nuclear post


August 5, 2013

President Barack Obama announced his nomination of Kenneth L. Mossman, an Arizona State University professor of health physics and an international expert in radiation health and safety, to the Defense Nuclear Facilities Safety Board on July 31.

The board is a small executive branch agency (five members) with safety oversight of all nuclear weapons facilities in the U.S. It acts as an independent agency to identify the nature and consequences of potential threats to public health and safety at the Department of Energy’s defense nuclear facilities, to elevate such issues to the highest levels of authority and to inform the public. It makes recommendations on matters of safety to the Secretary of Energy and to the President. Download Full Image

“I am excited about working with other Presidential appointees on the board and the very talented civil servants who carry out the work of the board,” Mossman said. “I have always had a strong commitment to giving back, particularly to institutions that have contributed to my success. This Presidential appointment is another way of giving back. Other than teaching there is no greater calling than government service in the public interest.”

Mossman has published widely on topics such as biological effects of low and high dose x-, gamma and neutron radiation; radiation exposure during pregnancy; the health effects of radon; and radiation protection and public policy. His current research includes nuclear regulatory science and policy, and managing small risks, as well as risk perception and risk communication.

Mossman has held his current position as professor of health physics at ASU since 1990. He is also an administrative judge for the Nuclear Regulatory Commission’s Atomic Safety and Licensing Board, where he has served since 2008.  

From 1997 to 2004, Mossman was director of the University Office of Radiation Safety at Arizona State University, and from 1990 to 1992 he served as the University’s assistant vice president for research. Previously, he was a professor at Georgetown University’s Medical Center (1973 to 1990), and he was the founding chairman of the Department of Radiation Science at the Georgetown Graduate School (1982 to 1990).

Mossman received a bachelor's degree from Wayne State University, a master's and doctoral degree from the University of Tennessee and a master's of education from the University of Maryland.

Mossman’s Senate confirmation process is expected to begin this fall.

ASU researcher spots rare snow leopard in Russia's Altai Mountains


August 5, 2013

What does it take to be among only a handful of people who have ever reported spotting one of the most elusive, well-camouflaged and endangered big cats in the world – a snow leopard? According to Arizona State University researcher Mimi Kessler, a combination of great company, a keen eye and good luck may be the key.

Kessler, a doctoral candidate at ASU’s School of Life Sciences, spotted a snow leopard recently in Russia’s Altai Mountains. She says every sign, image and sighting leads to a better understanding of the endangered species. Download Full Image

Called “ghost of the mountains” by locals, the snow leopard spends most of its life alone and remains scattered in the Tien Shan, Altai-Sayan and Himalayan mountain ranges of Central Asia. Russia is home to only about 90 snow leopards, of which 30 to 40 are said to be in the Altai Mountains.

“The odds were against us – this creature is rare and wary, the territory it inhabits is large and the time we had was relatively short,” Kessler, a biologist and ornithologist, says. “I expected to observe, at best, scrapes and signs left by the cat, not the creature itself, so it was a fantastic surprise. I could hardly sleep that night, remembering the events of the day.”

Spotting the snow leopard

Kessler was in the Altai Mountains as part of the Wild Altai expedition, a program run by an American non-profit, called The Altai Project, that promotes conservation of biodiversity and community development in the region. Kessler, fluent in Russian and trained in Altai language, volunteered as a linguistic and cultural liaison for the group while on the lookout for rare birds, especially the Asian Great Bustard – the heaviest bird capable of flight and subject of her long-term conservation research.

The team – guided by experienced snow leopard researchers Sergei Spitsyn from Arkhar/Altaisky State Nature Reserve, Mikhail Paltsyn from World Wildlife Federation-Altai Sayan and The Altai Project’s director, Jennifer Castner – was hiking in a mountain range close to the Mongolian border to download images from motion-sensing cameras that have been deployed in the area for two years. 

After viewing images of a snow leopard clicked that very morning by the cameras, a smaller group comprised of Kessler and three members of the Wild Altai expedition continued to hike and eventually stopped for a drink of water. Kessler scanned the surrounding mountains with her binoculars out of habit.

“The first thing I noticed was a pair of pointy ears on top of a ridge less than 200 meters from us,” Kessler says. “Since I work with birds, my first thought was that they might belong to an owl. But on closer inspection, I saw the silhouette of a cat on the ridge-top. We were looking directly at each other.

“Once I was certain of what I was seeing, I told the rest, 'You are not going to believe this, but there is a snow leopard on that ridge.' My companions grabbed their binoculars, took a look and started yelling with joy. The cat continued to look at us for a few moments, then slowly walked further up the ridge and out of sight.”

A step closer to understanding the extraordinary snow leopard

According to the International Union for Conservation of Nature and Natural Resources, the Russian snow leopard is threatened by illegal poaching for hides and bones, poor anti-poaching enforcement and predator-prey conflicts.

Kessler says that each sighting and image of a snow leopard helps researchers and conservationists to better understand their range and abundance in their natural habitat. Only 20 people have ever reported viewing a snow leopard in the Russian Altai; Kessler, Castner and the two other expedition members are the only women who have ever reported viewing a snow leopard in Russia. 

Castner was also able to document the big cat with her camera before it disappeared; the images are only the second of the creature to be taken by a live observer in Russia. She asserts that conserving native wildlife in the Greater Altai region is of utmost importance.

“Human development and the natural environment in the Altai Republic are struggling to coexist,” Castner said. “On one hand, we have an incredibly well-preserved remote wilderness that serves as a habitat for snow leopards, argali sheep and other threatened species; on the other, a boom in tourism has led to increased development and human presence in sensitive natural areas. Our goal is to encourage sustainable community development and protect endangered species in the region.”

Kessler and Castner say spotting the snow leopard was an unforgettable experience. Kessler elaborates:

“I had considered trying to take a photograph but didn’t want to waste precious time fumbling with my camera. I knew that these few seconds were my only chance to observe this cat in a natural setting. As a biologist and naturalist, I wanted to take in as much as I could about its appearance, gait and behavior – a memory that will last a lifetime.”
