The Download: memory prosthesis, and rising nuclear plant risks

Plus: inside the hunt for massive hailstones

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.

A memory prosthesis could restore memory in people with damaged brains

The news: A unique form of brain stimulation appears to boost people’s ability to remember new information—by mimicking the way our brains create memories. The “memory prosthesis,” which involves inserting an electrode deep into the brain, also seems to work in people with memory disorders—and is even more effective in people who had poor memory to begin with, according to new research.

How it works: The memory prosthesis works by copying what happens in the hippocampus—a seahorse-shaped region deep in the brain that plays a crucial role in memory. The brain structure not only helps us form short-term memories but also appears to direct memories to other regions for long-term storage.

Why it matters: In the future, more advanced versions of the memory prosthesis could help people with memory loss due to brain injuries or as a result of aging or degenerative diseases like Alzheimer’s, say the researchers behind the work. Read the full story.

The big story

Where computing might go next

October 2021

If the future of computing is anything like its past, then its trajectory will depend on things that have little to do with computing itself. 

Technology does not appear from nowhere. It is rooted in time, place, and opportunity. No lab is an island; machines’ capabilities and constraints are determined not only by the laws of physics and chemistry but by who supports those technologies, who builds them, and where they grow. 

The future of computing feels more tenuous, harder to map in a sea of information and disruption. That is not to say that predictions are futile, or that those who build and use technology have no control over where computing goes next. But there are limits to the power of technology to overcome earthbound realities of politics, markets, and culture. To understand computing’s future, we must look beyond the machine.
