This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.
Hydropower is the world’s leading source of renewable electricity, generating more power in 2022 than all other renewables combined. But while hydropower is helping clean up electrical grids, it’s not always great for fish. Dams can change their habitats. And for migratory species, hydropower facilities can create dangerous or insurmountable barriers.
That’s why, in some parts of the world, governments have put protections in place to protect ecosystems from hydropower’s potential harms. These can sometimes force older facilities to close, and that’s a big problem: pulling hydropower plants off the grid eliminates a flexible, low-emissions power source that can contribute to progress in fighting climate change.
But there’s some good news: new technologies, including fish-safe turbines, could help utilities and regulators come closer to striking a balance between the health of river ecosystems and global climate goals. Read the full story.

Although significant attention has been devoted to launching spacecraft into space, the idea of what to do with their remains has been largely ignored until recently. Satellites have simply been left in orbit at the ends of their lives, creating debris that must be monitored and, if possible, maneuvered around to avoid a collision.
But there are people working on cleaning Earth’s orbit up. Meet Stijn Lemmens. He’s a senior space debris mitigation analyst at the European Space Agency. Lemmens works on counteracting space pollution by collaborating with spacecraft designers and the wider industry to create missions less likely to clutter the orbital environment. Read all about him and his work.

The big story
A brief, weird history of brainwashing
On a spring day in 1959, war correspondent Edward Hunter testified before a US Senate subcommittee investigating “the effect of Red China Communes on the United States.”
Hunter discussed a new concept to the American public: a supposedly scientific system for changing people’s minds, even making them love things they once hated.
Much of it was baseless, but Hunter’s sensational tales still became an important part of the disinformation and pseudoscience that fueled a “mind-control race” during the Cold War. US officials prepared themselves for a psychic war with the Soviet Union and China by spending millions of dollars on research into manipulating the human brain.
But while the science never exactly panned out, residual beliefs fostered by this bizarre conflict continue to play a role in ideological and scientific debates to this day. Read the full story.
