What fusion’s breakthrough means for clean energy
The News: After decades of trying, scientists have reached a milestone in fusion research, finally running a reaction that created more energy than was put in to start it. US Energy Secretary Jennifer Granholm announced on Tuesday that researchers at the Lawrence Livermore National Laboratory had achieved what’s known as net energy gain, a symbolic victory for nuclear fusion research.
How they did it: In fusion reactions, whether in a reactor or the core of a star, atoms are slammed into each other until they fuse, releasing energy. The goal of fusion energy is to get more energy out of the reaction than what’s put in to energize it. The fusion reaction at NIF achieved it, generating 3.15 megajoules of energy, more than the 2.05 megajoules provided by lasers used in the reactor.
What’s next: The advance demonstrates the basic viability of fusion energy, a goal researchers have been chasing since the 1950s. But the scientific experiment is not an immediately practical route to fusion power. Read the full story.

Neuroscientists have created a mood decoder that can measure depression
What’s new: Researchers from Baylor College of Medicine in Houston, Texas say they’ve developed a “mood decoder”—a way of being able to work out how someone is feeling just by looking at brain activity. They also say they can stimulate a positive mood using electrodes implanted in the brains of volunteers with depression.
Why it matters: Depression is a complicated illness—partly because we still don’t fully understand what’s going on in the brain when it occurs. Neuroscientists hope that by getting a better idea of what’s happening inside the brains of people with depression symptoms, they can make the treatment more effective.
What’s next: The scientists involved in the trial hope the decoder will help them to measure how severe a person’s depression is, and target more precisely where the electrodes are placed to optimize the effect on the patient’s mood. Read the full story.

How to live-tweet the Cultural Revolution, 50 years later
Twitter, at its best, gives strangers the chance to connect because they’re both interested in the same random thing. Jacob Saxton, a 30-year-old logistics analyst living in Southampton, UK, is the brains behind a particularly niche account: Cultural Revolution OTD 1972 (@GPCR50). The account pretends to live-tweet what happened during the devastating political movement from 1966 to 1976 in China—except, of course, it’s 50 years late.
Saxton’s tweets offer up a mixture of news events, peculiar anecdotes, historical pretext for modern issues, or snippets of profound violence and tragedy. And this combination of historical records being shared through a retroactive “live-tweeting” lens is particularly interesting because it’s being done by someone with no background in Chinese history.

The big story
Inside the experimental world of animal infrastructure
June 2022
Around the world, cities are building a huge variety of structures intended to mitigate the impacts of urbanization and roadbuilding on wildlife. The list includes green roofs, tree-lined skyscrapers, living seawalls, artificial wetlands, and all manner of shelters and “hibernacula.”
But the data on how effective these approaches are remains patchy and unclear. That is true even for wildlife crossings, the best-studied and most heavily funded example of such animal infrastructure.
Though road ecologists know these crossings can play a vital role in reducing roadkill, the story of their impact on wildlife conservation is still being told. Read the full story.
