The situation in Ferguson, Missouri is a reminder of the deep racial division in America.
Protesters in Ferguson and across the United States feel that Michael Brown was singled out by police because of his race.
CNN contributor L.Z. Granderson says there is a lack of trust between minorities and police, as well as a lack of empathy between blacks and whites in the country.
It's a problem he's experienced way too often.
"I've lost count the number of times I've been pulled over by a police officer," he tells me from Ferguson. "The first time that an officer pulled a gun out on me, I was 12 years old. He told me I looked like someone."
"We're talking about a 30 year gap in my life in which I continue to look like someone that police are interested in," Granderson says. "I have never committed a crime. I have never been prosecuted. But I keep feeling I am being persecuted."
Here's Granderson on the racial divide in America and the anger surrounding the Ferguson grand jury decision.
Take a listen. It's worth your time.
As Hong Kong's Umbrella Movement stretches into week nine, more barricades are coming down in the district of Mong Kok. So should pro-democracy protesters withdraw or wait it out?
One high-profile supporter is urging student leaders to stand down.
"It's about time we retreat," says Jimmy Lai, a fervent China critic and media mogul. He has been working from his protest camp in Admiralty since the start of the action.
Lai calls the Umbrella Movement a "war" that will extend far beyond the battle of the last two months.
He fears that growing public resentment to the protests, which has caused major traffic disruption throughout the city, will damage the pro-democracy movement.
According to a poll released by the University of Hong Kong last week, 8 out of 10 people surveyed think the demonstrators should leave the streets and go home.
"If we will lose the moral high ground, it will be very difficult for us to come back later," Lai tells me.
Click on to hear Lai's call for the protesters to retreat, regroup and return at a later time.
A jolt of energy has just hit the International Space Station.
In days that can feel like endless nights, what’s more welcoming than a burst of caffeine?
But with Italy’s first female astronaut now on board, regular old space coffee just won’t do.
Samantha Cristoforetti brought with her the very first zero-gravity espresso machine.
Call it the elephant in the room. It may be a cliché, but the fact that elephant populations are dwindling around the world is a growing problem that can’t be ignored.
Africa has seen its elephant population decline from 1.3 million several decades ago to an estimated 419,000 now. Poaching still goes unchecked in some parts of the continent.
Tanzania lost 10,000 elephants to poaching last year alone – more than any other country in Africa.
And the EIA makes damning allegations about China, the world's largest ivory market. It links some smuggling to Chinese officials who have accompanied the president to Africa. Beijing has denied the claims.
But it’s not just African elephants facing a perilous future. Their Asian cousins are also in a battle for survival. FULL POST
An American nurse has become the first person to contract Ebola in the U.S., raising fear and alarm about the outbreak in the West.
In the Ebola hotzone of West Africa, desperation grows as thousands of people are struck by the deadly virus - including healthcare workers on the front line.
The outbreak may be spreading, but professor and senior United Nations advisor Jeffrey Sachs tells me Ebola can be controlled in 6 months.
"This is a controllable epidemic but the epidemic has so far outrun the control efforts," he says.
"This is logistics, it's equipment, it's basic health protocols, it's diagnostics. All the pieces of a basic control system that need to be rapidly scaled up."
Watch the video to hear his recommended next steps, and what is at stake for Africa and the world if Ebola is not contained.
It has been dubbed the "Umbrella Revolution." But that isn't the only symbol to come out of Hong Kong's pro-democracy protests.
Local artist Kacey Wong also explains the meaning of the yellow ribbons and numbers spotted on signs.
He believes there is a lot at stake during this demonstration for universal suffrage.
"Right now I can see this war on culture. The winners will get to keep their way of life and their culture. And if you lose in this war, we have to fall back," Wong says. "We don’t want to fall back into the chaos that we read in the news from mainland China. I think it is time for mainland government officials to learn that if they want to join the international community, they have to behave in a civilized way. And this is a golden opportunity."
Thirteen years ago, Apple was a small computer maker. It's now the most valuable company in the world.
And that transformation was triggered by the iPod.
Apple has quietly discontinued the iPod Classic, the latest incarnation of the original iPod. While the line lives on in the shape of the Touch, Nano and Shuffle, they aren't as iconic as the original. When you think iPod, you think of the Classic: Shaped like a deck of cards, with a metallic back, and of course, the scrollwheel.
But the original design lives on in one tiny way: The top row of icons on the Apple Store includes the classic iPod silhouette.
Few realize that many of the first video games were multiplayer. It took time for computers to be smart enough to provide decent opponents, leading to the rise of singleplayer games.
Now Destiny is about to introduce gamers to a new type of gaming: mingleplayer. FULL POST
Apple is strengthening security features after the high-profile hack attack that released celebrities' private photos.
Those nude images were posted online just nine days before Apple's next launch event. The company is expected to unveil a wearable device on September 9.
CNN Contributor Nicholas Thompson points out that this is the first time Apple is launching a new product category under Tim Cook's leadership.
"Up until last week, everybody thought this would be his great moment to shine. There was huge anticipation and excitement. And now suddenly there's this hack," Thompson says.
But that's not the only reason this attack comes at a bad time for Apple.
"They haven't done as well with cloud services. So iCloud is not as good as some of their competitors. It still has flaws," Thompson says. "Having this big problem makes some people wonder in the tech industry, 'Can Apple really succeed in this next step in the evolution of the industry?'"
Watch the video above to hear why Thompson thinks Apple can get the cloud under control, and learn how to protect yourself online.
