Article: A meteorite flew fast across the sky and exploded over central Russia on Friday, raining fireballs over a vast area and causing a shock wave that smashed windows, damaged buildings and injured l,200 people. People heading to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt the shock wave. According to Russian space agency Roscosmos, the fireball, travelling at a speed of 30km per second, had burnt very brightly across the horizon, leaving a long white trail that could be seen as far as 200km away. Car alarms went off, thousands of windows shattered and mobile phone networks were disrupted. "I was driving to work, it was quite dark, but it suddenly became as bright as if it were day," said Viktor Prokofiev, 36, a resident of Yekaterinburg in the Urals Mountains. "I felt like I was blinded by headlights." The meteorite, which weighed about 20 tons and may have been made of iron, entered Earth's atmosphere and broke apart 30-50km above ground, according to Russia's Academy of Sciences. The energy released when it entered the Earth's atmosphere was about several thousand tons, the academy said, the power of a small atomic weapon exploding. No deaths were reported, but the Emergencies Ministry said 20,000 rescue and clean-up workers were sent to the region after President Vladimir Putin told Emergencies Minister Vladimir Puchkov to ease the disruption and help the victims. The Interior Ministry said about l,200 people had been injured, at least 200 of them children, and most from broken pieces of glass."While events this big are rare, an impact that could cause damage and death could happen every century or so. Unfortunately there is absolutely nothing we can do to stop impacts."
Answer: In the early morning.
When did the meteorite incident happen?

Article: Forty years ago, Finland was a small country with ordinary public schools. Today, Finland is still small but no one calls Finland's public schools ordinary anymore. In 2000, the Finns surprised the world when their 15yearolds scored at the top of a closelywatched international exam called the PISA, the Program for International Student Assessment. Finland has stayed near the top ever since, while the US scores around the middle. Pasi Sahlberg, an official of Finland's Ministry of Education and Culture, is in Seattle this week to share the story of Finland's success, and what states like Washington can learn from it. Sahlberg's message, although he is too polite to put it so directly: Stop testing so much. Trust teachers more. Give less homework. Shorten the school day. On Tuesday, in a room filled with teachers, principals, professors, schoolboard members and policy makers, Sahlberg joked about the Finns' reputation for being a quiet, humble people. When Finland hit the top of the PISA, he said, the biggest disbelievers were Finns. More seriously, he said, Finland never set out to create the world's top school system. Instead, he said, the country decided in the 1970s that it wanted to ensure that a student's success didn't depend on family background. To achieve that goal, Finland relied on cooperation among teachers and schools, rather than on competition. Rather than judges teachers and schools based on test scores, he said, Finland puts trust in its teachers and principals. Teachers develop the curriculum in Finland, and design their own tests. There are no national tests, except one at the end of high school. That's just the start. Along with a shorter school day, Finnish students don't even start school until they are 7 years old. Many primary schools have a policy against giving homework. But Finland, he said, succeeded in part by adapting ideas from the US and other countries. And those countries, he said, can learn from Finland, too.
Answer: To share the story of Finland's success in education.

Article: Many people cannot start their day without first having a cup of coffee or tea.These drinks help them think clearly and feel more awake.This is because of caffeine,which helps to give a jump start to the nervous system.Now,a report says it may also boost long-term memory. Mike Yassa is a neurobiology professor.He and other researchers wanted to know if caffeine could improve a person's memory.He explains,"After you learn anything,it takes some time for that memory to strengthen.And over the first 24 hours is actually where most of the forgetting happens.So that is where we wanted to intervene with caffeine and see if we can help reduce this forgetting." They took 160 caffeine-free people and showed them pictures of everyday objects. These people were asked if the objects could be found inside the house, or outdoors.Then some of the subjects were given a caffeine pill.The others were given a placebo--a pill containing nothing. 24 hours later,the subjects were shown the exact same images from the day before.They were also shown images with slight differences,and some completely new images. Both groups correctly identified the exact same and completely new pictures.But those who took the caffeine pill were better at spottingthe pictures that were slightly different. Professor Yassa says their answers helped to show the effects of caffeine on memory. And we find that if they are on caffeine they are much more likely to make the right decision." The amount of caffeine the researchers used in the study was similar to one cup of strong coffee.The researchers did not see any improvement to memory from smaller doses of caffeine or when it was given an hour before viewing the images.
Answer: Caffeine can make people feel comfortable.
