How one controversial startup hopes to cool the planet
Stardust Solutions believes that it can solve climate change—for a price.
The Israel-based geoengineering startup has said it expects nations will soon pay it more than a billion dollars a year to launch specially equipped aircraft into the stratosphere. Once they’ve reached the necessary altitude, those planes will disperse particles engineered to reflect away enough sunlight to cool down the planet, purportedly without causing environmental side effects.
But numerous solar geoengineering researchers are skeptical that Stardust will line up the customers it needs to carry out a global deployment in the next decade. They’re also highly critical of the idea of a private company setting the global temperature for us. Read the full story.

One more thing
The entrepreneur dreaming of a factory of unlimited organs
At any given time, the US transplant waiting list is about 100,000 people long. Thousands die waiting, and many more never make the list to begin with. Entrepreneur Martine Rothblatt wants to address this by growing organs compatible with human bodies in genetically modified pigs.
In recent years, US doctors have attempted seven pig-to-human transplants, the most dramatic of which was a case where a 57-year-old man with heart failure lived two months with a pig heart supplied by Rothblatt’s company.
The experiment demonstrated the first life-sustaining pig-to-human organ transplant—and paved the way towards an organized clinical trial to prove they save lives consistently. Read the full story.
