WSU researchers investigate effect of environmental epigenetics on disease and evolution

Washington State University researchers say environmental factors are having an underappreciated effect on the course of disease and evolution by prompting genetic mutations through epigenetics, a process by which genes are turned on and off independent of an organism’s DNA sequence.Their assertion is a dramatic shift in how we might think of disease and evolution’s underlying biology and ‘changes how we think about where things come from,’ said WSU biologist Michael Skinner. —> Read More

70 Years After Hiroshima, Disarmament Is Still Vital

Co-authored by Ken Olum, research professor in the Physics and Astronomy Department, Tufts University.

A little over 70 years ago, our father, Paul Olum, stood with his colleagues in the desert near Alamogordo, New Mexico. They had spent the last two and a half years designing a new weapon, the first atomic bomb, and now they waited to see whether it would work. Then the explosion seemed to fill the sky, until it resolved into a huge mushroom-shaped cloud. The project had succeeded. They had designed and built the most powerful weapon ever seen on Earth.

Three weeks later, on August 6, 1945, the United States dropped an atomic bomb on Hiroshima, and, three days after that, another bomb on Nagasaki. The two bombs together killed over 100,000 people instantly, and a similar number died later from radiation exposure. Paul had mixed feelings about the bombing of Hiroshima. It seemed clear it would end the war swiftly, but there had been a very high cost in civilian lives. However, he felt the bombing of Nagasaki was unconscionable, because three days had not been long enough for the surrender.

Six days after the bombing of Nagasaki, Japan did announce its surrender. World War II was over, but the nuclear arms race had begun, and Paul Olum became a lifelong advocate of nuclear arms control and disarmament.

By the 1980s, the United States and the Soviet Union together had amassed about 27,000 “active” strategic nuclear bombs each hugely more powerful than those that destroyed Hiroshima and Nagasaki. The arsenals of either nation were sufficient to destroy humanity many times over.

Paul had been only 24 years old when he and our mother Vivian went to Los Alamos in 1943. After the war was over, he went on to a distinguished career as —> Read More
