Solar Power: How to Win the West
As the railroads shaped the American West in the 19th century, a new electrical generating and transmission system for the 21st century will leave its lasting mark on the desert.
The sun-baked desert of the American southwest is the most obvious place for a large solar energy infrastructure, says Jon Christensen, executive director of the Bill Lane Center for the American West at Stanford University. "We need alternative energy sources badly, and to really take advantage of them we need to be able to move electricity around far more readily than we can now. The western power grid is a fragmented hodgepodge. It needs to be much better integrated. And that is going to require major power lines across the West. Trade-offs will have to be made. ..."

Rediscovering the principles of self-actualisation might be just the tonic that the modern world is crying out for.
Abraham Maslow was the 20th-century American psychologist best-known for explaining motivation through his hierarchy of needs, which he represented in a pyramid. At the base, our physiological needs include food, water, warmth and rest.
"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.
Does believing in true love make people act like jerks?
- Ghosting, or the practice of cutting off all contact suddenly with a romantic partner, is a controversial method of dumping someone.
- People generally agree that it's bad form, but new research shows that people have surprisingly different opinions on the practice.
- Overall, people who are more destiny-oriented (more likely to believe that they have a soulmate) tend to approve of ghosting more, while people who are more growth-oriented (more likely to believe relationships are made rather than born) are less tolerant of ghosting.
