Thanks to Cagle Post and Class Brain you can learn about news in a funny way. Do you remember this topic from last year in your science class?
"Reversing the precedents set during the Bush years, President Obama has freed up scientific inquiries into stem cell research. Scientists have been frustrated through the past decade by former President Bush's stance that despite the great promise shown by stem cell research, only 60 stem cell lines were to be used for research, since they had already been created. Who would get to use the lines, and how many experiments could they run with the small amounts of genetic material available?
Some of the most promising research with stem cells has been related to Parkinson's disease and spinal cord injuries. Now that the moratorium has been lifted, substantial progress may be seen in these particular fields.
Now some questions to think:
• Do you think that stem cell research should be allowed to progress, or do you think the moratorium should continue?
• Do you think that the moratorium on Stem Cell Research was influenced by former President Bush's religious background?
•If you were President, would you ban or allow stem cell research during your term in office?
•How real are the fears of human cloning?

Half of American teenagers don’t get enough sleep on school nights. They get an average of 60- 90 minutes less than they need, experts say. One problem is biology. Teens are programmed to go to sleep later and wake up later than other age groups, but many schools start classes as early as 7:00 a.m. Many students go to class feeling tired. One student, Danny, says that getting up in the morning is terrible. He feels tired. During his first classes of the day, it’s difficult to stay awake. Michael Breus is a psychologist. He’s an expert in sleep problems. He says that teenagers need eight to ten hours of sleep a night. He feels that sleepy teens can become depressed. This can also affect their ability in sports and driving. Michael Breus says a tired driver, especially a tired teenage driver, is dangerous. What can schools do? Psychologists say schools can start classes later in the morning. Studies show that students’ grades improved by starting classes later. St. George’s School in Rhode Island wanted to try this. They started classes just thirty minutes later. Visits to the health center by tired students decreased by half. Late arrivals to first period decreased by one/third. Students felt less sleepy during the day. The teachers also noticed that students were happier and more awake.
