A growing body of evidence, dating back to the late 1960s, suggests that we can lessen the emotional blow of negative memories (and even get rid of them altogether) months and years after those memories originally formed. The key is that memories seem to be vulnerable to manipulation and erasure as you're recalling them, not just at the time of creation. The newest research — and some of the most convincing to date — used electroconvulsive therapy to effectively remove the details of traumatizing stories from the minds of healthy volunteers. Virginia Hughes has a story about the newest study at her blog:
Schiller’s experiments have also bolstered the reconsolidation hypothesis. She has shown, for example, that if people recall a fearful memory and then go through ‘extinction learning’ — meaning that they’re shown the fearful stimulus over and over again without any pain — they can erase the emotional sting of the memory. Other groups have shown something similar by giving people propranolol, a beta-blocker, immediately after recalling a memory.
The new study adds ECT to the list. There are still a lot of questions. For example, it’s not clear how ECT is disrupting reconsolidation. Or if it’s doing it at all: The effect could be partly or wholly due to anesthesia, though the researchers say this is unlikely. Most importantly, no one knows whether the procedure would work with old, real memories, as opposed to those artificially created in the lab.

To demonstrate the Magnus effect, YouTuber PeterSripol grabbed a couple of KFC buckets and tricked out an RC plane. The resulting trial and error is mostly the latter.
One of the weirdest places in Antarctica is Blood Falls, a five-story cascade of blood-red liquid pouring from Taylor Glacier. Researchers finally traced its source: a saltwater lake millions of years old trapped under the glacier.
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
