Problem: Boston (CNN)She knew something awful had happened. It was smoky and all she could hear were muffled screams. Her foot was turned sideways and her legs wouldn't work right. And her good friend, Krystle Campbell, was just lying there on the ground.

Karen Rand -- she's Karen McWatters now -- dragged herself across the pavement. She wanted to get closer to Krystle so they could talk and take comfort from each other in the midst of so much chaos.

"I got close to her, " she recalled. "For some reason, I got close to her head and we put our faces together."

Krystle said that her legs hurt. They were the last words she'd speak. The two women held hands until Krystle's went limp.

McWatters was the fifth witness of the first day of the terror trial of accused Boston Marathon bomber Dzhokhar Tsarnaev, who is accused of detonating pressure cooker bombs with his brother to punish the United States for policies they believe inflict suffering on Muslims.

Three people were killed in the blasts: Campbell, a 29-year-old manager for a restaurant chain; Martin Richard, an 8-year-old boy; and Lingzi Lu, a 23-year-old grad student.

More than 250 others were injured. And the first day of the trial -- after opening statements -- revolved around a number of survivors of the attack, who recounted in detail the chaos of that day. Prosecutors called them to the stand to paint a picture of the havoc and pain the bombings inflicted. Tsarnaev's attorneys chose not to cross-examine any of the survivors.

Problem: With the passing of Steve Jobs, the tech industry has lost one of its most respected heroes. So where will the industry turn for inspiration, now that Jobs is gone?

New Apple CEO, Tim Cook, will keep the business going, but he is unlikely to inspire the same kind of devotion as Jobs. Facebook owner, Mark Zuckerberg, has star power, but he and his company are still too young and untested. At Google, Larry Page is too awkward, and Eric Schmidt too clever, and a lot of the company's recent products are unfinished. But there's one tech leader who just might fill the gap: Amazon's Jeff Bezos.

Bezos runs his business the same way as Steve Jobs ran his, with a focus on long-term value over short-term profits and a willingness to invest in seemingly unrelated new areas. Steve Jobs converted Apple from personal computers into music with the iPod, and then into cellphones with the iPhone. It worked, and made Apple into the biggest and richest tech company in the world. Jeff Bezos is doing the same thing at Amazon.

In 2006, Amazon noticed it had a lot of spare capacity in its data centers. So it started renting out some of that capacity to some companies. Now, hundreds of newly-established Internet companies, including big names like Foursquare and Yelp, run their businesses on Amazon Web Services. Somehow, an outline bookseller became the most important provider of "cloud computing".

In 2007, Amazon introduced its e-reader, the Kindle. The product developed slowly for a couple of years, and then started to take off in 2010 with the third generation. It sells for US$199, which is hundreds of dollars less than Apple's iPad, but it has similar functions to the iPad. No wonder Amazon has to build millions more than it expected to meet demand.

Problem: For many girls, having long beautiful hair is something to beproud of. Rachel Barrett, 15, recently cut her long hair and lookedlike a boy. But she was also proud of herself. She donated herhair to a charity and raised a lot of money.Barrett is a middle school student in Britain. On Nov. 16 at her school's talent contest, Barrett had her hair cut off in front of around 300 students. The hair would be used to make wigs for children with cancer. She has raised several thousand pounds and the money will help people with breast cancer . Barrett got the idea when she visited her friend's mom with cancer. "All of her hair had fallen out, and it really made me want to do something," Barrett said. When she found out that the charity Little Princess Trust could make wigs for children with cancer, she decided to donate her own hair, even though she loved it. "I saw how sad it was for my friend's mom to lose her hair. So if my hair can go to help a young child with cancer then it's worth it," she said. Cath Stanton, a teacher, felt proud of the girl.
