Odds and ends for July 17


‘Vanishing’ tech gear is in the works

URBANA, Ill. (AP) — Imagine this: There’s no need to throw out your old cellphone, because it will self-destruct.

That’s the idea behind a project at the University of Illinois at Urbana-Champaign, where researchers are investigating how to build electronics that vanish in water.

John Rogers is a professor of Materials Science and Engineering at the university. Rogers says the goal of the “born to die” program is to design transient technology that can dissolve at the end of its useful life, thus saving space in landfills and reducing waste.

The research team isn’t there yet. But it has designed a chip built on a thin film of silk that dissolves when hit with water.

Wonder won’t sing in Fla. after verdict

NEW YORK (AP) — Stevie Wonder says he won’t perform in Florida and other states with a “stand your ground” law.

In a video posted on YouTube, the 63-year-old singer said at a concert in Quebec City, Canada, on Sunday “that until the ‘stand your ground’ law is abolished in Florida, I will never perform there again.”

Wonder added: “Wherever I find that law exists, I will not perform in that state or in that part of the world.”

The “stand your ground” law allows people to use deadly force if they believe their life is in danger.

George Zimmerman shot 17-year-old Trayvon Martin during a February 2012 confrontation in Sanford, Fla. Zimmerman said he fired his gun in self-defense.

A six-member jury acquitted Zimmerman of second-degree murder and manslaughter charges on Saturday.

Wonder’s representative said the singer had no further comment.
