An unknown suspect breached a computer system for the city of Oldsmar's water treatment plant on Friday and briefly increased the amount of sodium hydroxide from 100 parts per million to 11,100 parts per million, Pinellas County Sheriff Bob Gualtieri said during a news conference Monday....

A hacker recently tried to poison a Florida city’s water supply, police announced Monday. Pinellas County Sheriff Bob Gualtieri said someone remotely accessed a computer system that controls the City of Oldsmar’s water treatment facility on Friday. The unidentified person increased the amount of sodium hydroxide being distributed into the city’s drinking water to a “dangerous” level, Gualtieri said at a press conference. The chemical, also known as lye, is used in small amounts to control the water’s acidity — but can be deadly if ingested in large quantities. A worker at the plant immediately noticed the change and reversed...

Simple processes can make wood tough, impact-resistant—or even transparent Some varieties of wood, such as oak and maple, are renowned for their strength. But scientists say a simple and inexpensive new process can transform any type of wood into a material stronger than steel, and even some high-tech titanium alloys. Besides taking a star turn in buildings and vehicles, the substance could even be used to make bullet-resistant armor plates. Wood is abundant and relatively low-cost—it literally grows on trees. And although it has been used for millennia to build everything from furniture to homes and larger structures, untreated wood...
