Smoking causes extensive damage to DNA, study shows

“Tobacco smoking damages DNA in organs directly exposed to smoke as well as speeds up a mutational cellular clock in organs that are both directly and indirectly exposed to smoke.” said Ludmil Alexandrov of the Los Alamos National Laboratory in Los Alamos, New Mexico, who led the study.

In other words, it accelerates the occurrence of genetic mutations, increasing the risk of cancer.

"Before now, we had a large body of epidemiological evidence linking smoking with cancer, but now we can actually observe and quantify the molecular changes in the DNA due to cigarette smoking," Alexandrov said. (Full Story)

Humans on Mars

"Mars is in the air. We grew up with the Apollo program," said Patrick McClure, Los Alamos National Lab. "We really want to make that happen in our lifetime. We think it would be a great contribution to humanity."

Like his other far-flung team members, Los Alamos nuclear reactor scientist Patrick McClure is bubbling with enthusiasm about the end uses for the small nuclear reactor his team will test in the Nevada Desert in 2017. The reactor is named Kilopower. (Full Story)

Fermi biography takes readers to ground zero

A valuable new biography recognizes the lifelong contributions of a physicist who had roles in the work of all three legs of the project that developed the bomb – at Hanford, Wash., at Oak Ridge, Tenn., and at Los Alamos.

His name is Enrico Fermi.          

At Los Alamos Fermi was a valuable member of the team that fit “all the pieces together. He was the person to consult about almost any physics question.” Fermi, a native of Italy, received the 1938 Nobel Prize for Physics. (Full Story)
