The lambda is a baryon which is made up of three quarks: an up, a down and a strange quark. The shorter lifetime of 10-23 seconds was expected because the lambda as a baryon participates in the strong interaction, and that usually leads to such very short lifetimes.
The 2017 fire season in Montana has been devastating for many people and communities, and as of Sept. 6, more than one million acres of land has burned. The figure comes from the Northern Rockies Coordination Center. That is the third-largest acreage burned in more than two decades. This year, the total so far is 1,032,801 acres burned.

Both Idaho and Wyoming have their share of wildfires as well. The Pioneer and Rough Fires are both burning in Idaho. The Maple Fire is blazing around Yellowstone National Park in Wyoming.
