Future U.S. Nuclear Reactors
Nuclear reactors planned for the U.S. are safer and more efficient than the 40-year-old Japan facility that has suffered explosions and leaks, experts say. Still, their approval is likely to be delayed.
The biggest takeaway from the nuclear crisis unfolding in Japan will not concern the future technology of nuclear facilities, says University of Wisconsin engineering professor Robert Corradini and member of the Nuclear Regulatory Commission (N.R.C.). "'You're going to see refortification of plants for the tsunami. I expect that the N.R.C. is going to slow down the process and do a re-analysis to make sure that nothing has been unturned in terms of lessons learned.' Corradini says the 'Generation III-plus' plants proposed by Westinghouse, General Electric, Mitsubishi and the French firm Areva incorporate new designs that take in the lessons of past nuclear accidents at Three Mile Island and Chernobyl."

You can say 'no' to things, and you should. Do it like this.
- Give yourself permission to say "no" to things. Saying yes to everything is a fast way to burn out.
- Learn to say no in a way that keeps the door of opportunity open: No should never be a one-word answer. Say "No, but I could do this instead," or, "No, but let me connect you to someone who can help."
- If you really want to say yes but can't manage another commitment, try qualifiers like "yes, if," or "yes, after."
"I was so moved when I saw the cells stir," said 90-year-old study co-author Akira Iritani. "I'd been hoping for this for 20 years."
- The team managed to stimulate nucleus-like structures to perform some biological processes, but not cell division.
- Unless better technology and DNA samples emerge in the future, it's unlikely that scientists will be able to clone a woolly mammoth.
- Still, studying the DNA of woolly mammoths provides valuable insights into the genetic adaptations that allowed them to survive in unique environments.
Neuroscience research suggests it might be time to rethink our ideas about when exactly a child becomes an adult.
- Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.
- Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take pace well into one's 20s.
- The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s.
