We know it can be hard to keep up with everything that’s going on in the world, the country and your community. So here are five stories from the past week that you may have missed but really shouldn’t.
The most popular story on our site this week chronicled the latest chapter in the effort to rebuild the Oroville Dam spillway, which failed last February and led to mass evacuations. Federal regulators asked state water officials to explain small cracks that were found in some of the spillway's newly built concrete slabs.
A spokeswoman for the state Department of Water Resources said the cracks were the result of efforts to make the spillway stronger and were to be expected in concrete slabs of that size. But Robert Bea, a veteran analyst of structure failures, isn't quite convinced:
“Cracking in high-strength reinforced concrete structures is never ‘to be expected,’ ” Bea said in an email. Even small cracks could increase stresses in the concrete when it is under “service loading” — for instance, when large volumes of water hurtle down the structure at speeds approaching 90 mph.
A San Francisco jury has acquitted Jose Ines Garcia Zarate on murder and manslaughter charges in the 2015 death of Kathryn Steinle. Many people around the country -- including President Donald Trump and Attorney General Jeff Sessions -- have put a spotlight on the defendant's undocumented status and San Francisco's status as a so-called sanctuary city. But there was a lot more to this case:
- The bullet that killed Steinle ricocheted off the ground before traveling 78 feet and hitting Stenile, suggesting an accidental discharge.
- The prosecution was unable to present a motive for why Garcia Zarate would intentionally kill Steinle.
- The gun used in the killing was stolen from the car of a U.S. Bureau of Land Management ranger four days earlier. The ranger was later promoted.
Good news! The risk of being attacked by a shark on the California coast has dropped by more than 91 percent since 1950, according to Stanford researchers. Their best guess for the change is the resurgence of seals, sea lions and elephant seals, which provide sharks an attractive menu far from the California coastline.
