Q: Article: Almost all of us have been there: A sense of uneasiness strikes us when we see the battery running low on the smartphone. While today's smartphones enable us to surf the Internet, take pictures and play music, their limited, sometimes annoyingly short battery life has started to make people full of memories of early models. "My favorite phone of all time was a silver Nokia 6310i from the early 2000s. It may be primitive by today's standards, but it could run for 17 days on a single charge," wrote Daily Mail columnist David Derbyshire. But scientists spend no time thinking about the past. They have built an aluminium battery which could be a cheap, fast-charging alternative to current designs. You can squeeze, and practically bend it in half without breaking the packet. It is more environmentally friendly than alkaline batteries, and more safe than lithium batteries - it won't catch fire "even if you drill through it", as Hongjie Dai of Stanford University told The Telegraph. The battery is the work of a team led by Dai. And the best part is that it has a recharge time of around one minute. However, at present, the only problem is that it produces just half the voltage of a typical lithium battery. But Dai explained they were setting about changing the voltage and energy density ". "Our battery has everything else you'd dream that a battery should have. I see this as a new battery in its early days," he told The Telegraph.

Q: Article: As I was busy working on my work plan in my bedroom, I could hear my four children playing upstairs. Suddenly, I heard the children running down the stairs and shouting, "Freddie, Freddie." _ My three-year old son Freddie was lying on his side on the ground. I cried for my husband Simon to dial 999 and within minutes the air ambulance arrived. They quickly took him in the helicopter. During the flight, Freddie was looking at me and I remember thinking was a good sign, but then his eyes began to roll. As the doctors tried to stabilize him, I couldn't believe what was happening. When we arrived at the hospital in Portsmouth, there were some doctors and nurses waiting for us and they immediately set to work on Freddie. I was hopelessly wishing everything would be alright, but Freddie had broken his skull in two places and blood clots were forming in his brain. He needed surgery , and only a surgeon at another hospital in Bristol could do it. This meant another helicopter ride, but we couldn't go with Freddie because there was no enough space. Simon and I drove the long 130 miles from our home in north Devon in silence. Neither of us dared say what we were thinking, "What if we get there and he's dead?" "Is he going to be brain-damaged?" Freddie was just coming out of surgery when we arrived. The surgeon said it had gone well. When I finally saw him, I hardly recognize my child--he was covered in tubes and there were wires coming out of his head. On the third day, Simon went home to see our three girls and to pick up some clean clothes for us. While he was gone, the pressure in Freddie's brain suddenly increased. He was taken into theater again and this time I fell apart. Luckily, the surgery managed to stabilize Freddie. After almost a week, Freddie was finally woken up. When he opened his eyes, he looked at me. He didn't say anything, but I knew straight away that it was my old Freddie, and that he was going to be alright. Over the next two weeks, his recovery went well. After help with learning to swallow again and encouragement with speaking, he was soon playing with his Gruffalo cards and eating meals by himself. I still don't know how the accident happened, but we got some idea from our girls. Clearly Freddie and Minnie had been sitting on the window ledge, and Freddie must have opened it to look out and fallen 20 feet onto the ground below. The guilt I feel is awful-- for weeks I was full of " if onlys", and we put window locks everywhere. Six months later, although the accident seems a lifetime ago, it has changed me. I feel differently about life now. I've left my job to put my children first. I want to spend every minute with them.
Answer: Because no surgeons in the first hospital could do surgery on the author's son.

A: Why did the author's son have to be moved to another hospital in Bristol?

Q: Article: EDGEWOOD-Every morning at Dixie Heights High School, customers pour into a special experiment: the district's first coffee shop run mostly by students with special learning needs. Well before classes start, students and teachers order Lattes, Cappuccinos and Hot Chocolates. Then, during the first period, teachers call in orders on their room phones, and students make deliveries. By closing time at 9.20 a.m., the shop usually sells 90 drinks. "Whoever made the chi tea, Ms. Schatzman says it was good," Christy McKinley, a second year student, announced recently, after hanging up with the teacher. The shop is called the Dixie PIT, which stands for Power in Transition. Although some of the students are not disabled, many are, and the PIT helps them prepare for life after high school. They learn not only how to run a coffee shop but also how to deal with their affairs. They keep a timecard and receive paychecks, which they keep in check registers. Special-education teachers Kim Chevalier and Sue Casey introduced the Dixie PIT from a similar program at Kennesaw Mountain High School in Georgia. Not that it was easy. Chevalier's first problem to overcome was product-related. Should schools be selling coffee? What about sugar content? Kenton County Food Service Director Ginger Gray helped. She made sure all the drinks, which use non-fat milk, fell within nutrition guidelines. The whole school has joined in to help. Teachers agreed to give up their l ounge in the mornings. Art students painted the name of the shop on the wall. Business students designed the paychecks. The basketball team helped pay for cups.
