Dylann Roof murdered nine people in a church basement in Charleston in 2015.

He confessed to the massacre shortly after he was arrested. He didn't testify at trial and no witnesses were called on his behalf before he was convicted of federal hate crimes.

The most emphatic statements on Roof's behalf came from defense attorney David Bruck. For weeks, the prosecution had presented evidence that Roof is a white supremacist whose violent racism drove him to kill black people. Bruck asked the jury to consider how the 22-year-old came to believe the things he did.

Children's Whirligig Toy Inspires a Low-Cost Laboratory Test

20 hours ago

Scientists have found the inspiration for a lifesaving tool in an unusual place — a children's toy. The invention may soon help health care workers diagnose malaria in places where standard laboratory equipment is hard to find. Diagnosing malaria in the field isn't all that difficult, but you need a device called a centrifuge that can spin a blood sample very quickly, causing different types of cells in blood to separate from each other.

The online classified website Backpage.com said it has suspended its adult ad pages, citing government pressure about the content being shared there.

A 2016 Senate report called the website the "largest commercial sex services advertising platform in the United States" and said that "Backpage officials have publicly acknowledged that criminals use the website for sex trafficking, including trafficking of minors."

In 1889, Bethlehem Steel brought engineer Frederick Taylor on board in an attempt to streamline its vast operation.

Taylor had recently invented a theory of "time management" in which the same principles used to optimize machines was applied to people. Taylor stalked the floors of the Bethlehem plant armed with a stopwatch and a clipboard noting the time it took for workers to complete tasks, like loading iron bars onto waiting railcars. Taylor's eventual recommendation to the company's executives were simple: The workers should be made to do more in less time.

Media coverage of tragedy — terrorist attacks, homelessness, the refugee crisis — can be so overwhelming it's numbing. Charities say it can also make it harder to get support.

Some are hoping a new form of media will be more persuasive — virtual reality or VR, which they think makes people more empathetic.

Now let's note an anniversary.

KELLY MCEVERS, HOST:

To do that, imagine a world where no one is bent over a little glowing screen.

CORNISH: Or where confronted with a question at a dinner party, no one Googles the answer right at the table.

On Jan. 9, 2007, 10 years ago today, Steve Jobs formally announced Apple's "revolutionary mobile phone" — a device that combined the functionality of an iPod, phone and Internet communication into a single unit, navigated by touch.

It was a huge milestone in the development of smartphones, which are now owned by a majority of American adults and are increasingly common across the globe.

Chances are your doctor has stopped taking notes with pen and paper and moved to computer records. That is supposed to help coordinate your care.

Increasingly, researchers are also exploring these computerized records for medical studies and gleaning facts that help individual patients get better care.
