- In 1956, solar power was priced at about $1,865 per watt and survived largely because spacecraft needed lightweight power. Decades later, prices fell below 50 cents per watt and solar became the cheapest new electricitySolar power once cost a staggering $1,865 per watt in inflation-adjusted terms. Today, solar panels can cost only a fraction of a dollar pe...
- In the 1800s, Americans planted tamarisk for windbreaks and erosion control; by 2005, the tree had spread across western river systems and become a major management concernTamarisk was originally brought in for various practical applications, but it has since proliferated across western waterways. This invasiv...

- In 1967, US satellites searching for nuclear tests detected mysterious flashes from space. Decades later, scientists uncovered secrets of gamma-ray bursts, which can release more energy in 10 seconds than Sun will emit over its entire 10-billion-year lifetimeGamma-ray bursts, first detected accidentally in 1967, have long puzzled astronomers. Recent observations of their afterglows are now chall...
