The Download: resurrecting mammoths, and the climate bill’s big flaw

Sara Ord has one of the most futuristic job titles around—director of species restoration at Colossal Biosciences, the world’s first “de-extinction” company. Her team is figuring out how to turn Asian elephants into something resembling a woolly mammoth, by adding genes for cold resistance and thick red hair, in the hopes of creating an embryo, and eventually, an animal.

While there are no resurrected species yet, of course, Ord’s job is really about an imagined future, in which a high-tech combination of DNA technology, stem-cell research, gene editing, and artificial wombs could lead not just to the resurrection of lost species, but also to the preservation of those close to disappearing.

If everything goes smoothly, the company hopes to succeed in re-creating its first long-extinct animal, the striped marsupial predator the thylacine, by 2025. And, just like Jurassic Park, it may turn a profit by selling tickets to see them. Read the full story.

The US climate bill has made emission reductions dependent on economic success

In August, President Joe Biden signed the Inflation Reduction Act (IRA) into law, the largest US climate bill in more than a decade. In the months since, it has been enthusiastically welcomed by politicians, manufacturers, and scientists alike. But beyond enacting specific measures to reduce US carbon emissions by more than 40% by 2030, the IRA also fundamentally reframes how the government approaches climate change. 

Climate policy is now explicitly framed as an economic policy issue, dependent on economic policy success in ways that could complicate efforts to reduce US carbon emissions, and potentially add to the already formidable challenges facing its domestic clean energy industries. Read the full story.

The big story

Eight ways scientists are unwrapping the mysteries of the human brain

August 2021 

There is no greater scientific mystery than the brain. It’s made mostly of water; much of the rest is largely fat. Yet this roughly three-pound blob of material produces our thoughts, memories, and emotions. It governs how we interact with the world, and it runs our body.

Increasingly, scientists are beginning to unravel the complexities of how it works and understand how the 86 billion neurons in the human brain form the connections that produce ideas and feelings, as well as the ability to communicate and react. Here’s our whistle-stop tour of some of the most cutting-edge research—and why it’s important. Read the full story.
