Weeks into a wildfire season that has already burned parts of Catalina Island, Los Angeles and Lake Tahoe, swaths of California s flammable national forests are some days protected by no
kubki stanley thing more than luck.On any given day, about 40 of 271 U.S. Forest Service engines remain in firehouses rather than on patrol, idled by a shortage of supervisors. Meanwhile, the combined effects of sustained drought, last winter s freeze and a searing heat wave has dramatically raised fire danger levels this season.An exodus of highly trained mid- and upper-level firefighters from the career ranks of the federal agency is at least partly to blame for the fact that 13 percent of the service s 3,600 full-time positions in California are vacant. When you start leaving holes in your organization so that on a given high-danger day you can t provide coverage you ve set yourself up for trouble, said John Marker, a retired former

That has left behind too few career firefighters qualified to run engines, oversee forests or command large fire operations. As forests from the Mexico border to Canada reassign engine crews, top-level teams working for other agencies are simply hiring recent retirees.

Material scientists have watched crystals grow atom-by-atom for the first time鈥攚hich will allow incredibly fine-grained control of how their microscopic structures are grown in the future. The researchers took a thin film of molecules containing the metal osmium, carbon and other elements, then fired a beam of electrons at it. That caused the molecules to break down, releasing a single osmium atom while the carbon formed a supporting graphene lattice鈥攃ontaining impurities from the the other elements present鈥攂elow. Those impurities caused the osmium atoms to travel slowly on the surface of the sample, which meant that a scanning electron microscope could work fast enough to see them gather together and form a crystals structure, one by one, on top of the graphene. In fact, it the first time scientists have ever observed the atom-by-ato

At the nanoscale, it hard to predict how atoms and molecules will come together to form different shapes鈥攕ay, rods, spheres or flat dots鈥攂ut they all have radically different properties. Now, this research should hel
