Plants are extremely efficient converters of light into energy, more or less setting the bar for researchers creating photovoltaic cells that convert sunlight into electricity. As such, researchers are constantly trying to mimic the tricks that millions of years of evolution and development have taught to plant biology. Now, a team of MIT scientists believe they've done it, creating a synthetic, self-assembling chloroplast that can be broken down and reassembled repeatedly, restoring solar cells that are damaged by the sun.

The father of evolution apparently played God with a tropical ecosystem 160 years ago, and the results could inform future experiments to terraform Mars, botanists say.

The BBC recounts how Charles Darwin helped build an artificial forest on Ascension Island, one of his subjects of study from his trips on the HMS Beagle. Today, the island is home to species of plants that would not naturally co-exist. Darwin and his friends put them there, and nearly two centuries later, their grand experiment is living proof that we can transform natural environments. Read more »

Apparently, some tigers can change their stripes -- especially if they have books to sell. One of our favorite climate villains, the Danish economist Bjørn Lomborg, has apparently warmed to the idea of climate change, and now says it's a problem on which the world ought to spend $100 billion annually.

Lomborg's forthcoming book, Smart Solutions to Climate Change, declares that global warming is "undoubtedly one of the chief concerns facing the world today." He examines eight methods to reduce or stop it, including wave, wind, solar and nuclear power, as well as geoengineering, and advocates a carbon emissions tax to finance investment. Read more »
