You know that brain-training app you downloaded? It’s probably worthless

Add as a preferred source on Google

The idea of brain-training apps able to improve our cognitive abilities by playing games seemed like the perfect middle finger to everyone who ever told us to stop playing Sega and get on with some homework. Sadly, a new piece of research suggests that maybe we should have listened to our parents after all. According to a recent study from neuroscientists at Canada’s Western University, brain-training apps are great at … making you good at playing that particular brain-training app.

The researchers in the study examined whether playing one brain-training app for a period of several hours would make someone good at another brain-training app, utilizing the same part of the brain. Should this be the case, they theorized it would show that such apps can indeed improve a person’s working memory, which is crucial for countering memory loss and helping us better retain information.

This isn’t what they found, though. Instead, high scores racked up in the first game had no impact whatsoever on performance in the second game. In fact, scores were pretty much identical to those attained by a control group who hadn’t had the benefit of training on the first app.

“We hypothesized that if you get really, really good at one test by training for a very long time, maybe then you’ll get improvement on tests that are quite similar,” Bobby Stojanoski, a research scientist in the Owen Lab at Western’s Brain and Mind Institute and lead author of the paper, said in a statement. “Unfortunately, we found no evidence to support that claim. Despite hours of brain training on that one game, participants were no better at the second game than people who tested on the second game, but hadn’t trained on the first one.”

This doesn’t conclusively prove brain-training apps are useless, of course. It doesn’t act as a qualitative study of all brain-training apps, for one thing. It would also be interesting to see a follow-up which examines whether these apps could play a role in stopping the decline of neural function in older groups of people, similar to how people report doing crosswords or sudokus to keep their mind active.

For most of us, though, it seems that *sigh* we’re better off eating healthier, exercising regularly, and doing our homework on time in order to really train our brains.

A paper describing the work was recently published in the journal Neuropsychologia.

ChatGPT Pro replaced Gemini Notebook as my favorite research app, and I didn’t see it coming
Electronics, Phone, Mobile Phone

I've been using Gemini Notebook ever since it launched, and for the longest time, it was my go-to app for just about everything. Whether I was researching a topic, organizing work, or studying something new, it became one of those apps I instinctively opened without thinking. When Google kept adding new features, I genuinely believed it had secured a permanent spot in my workflow.

Then, almost without realizing it, ChatGPT Pro took over. I've been using its Work mode for a while now, and somewhere along the way, it replaced Gemini Notebook. Of course, it wasn't an overnight switch. I kept bouncing between the two for weeks, but I gradually found myself reaching for ChatGPT every single time instead. At some point, I realized I hadn't opened Gemini Notebook in days. Now, I honestly don't use it at all.

AI chatbots will happily create fake news articles, and tests show ChatGPT is the worst at it
Electronics, Phone, Mobile Phone

The biggest AI chatbots are supposed to help people find information, not manufacture misinformation. But a new investigation suggests that separating those two jobs isn't as straightforward as many AI companies would like users to believe. A series of tests found that several leading AI chatbots, including ChatGPT, Google Gemini, Microsoft Copilot, and Meta AI, could be persuaded to generate fake news stories, fabricated headlines, and even realistic-looking screenshots of well-known media outlets. While every chatbot showed some weaknesses, ChatGPT reportedly performed the worst, producing the most convincing fake content with surprisingly little effort.

The findings come from an investigation by German newsroom CORRECTIV, which tested how the AI assistants responded when asked to create false reports involving sensitive topics such as election fraud, government coups, war, vaccines, climate change, and conspiracy theories.

DeepSeek just slashed AI prices again, and China’s AI race is getting even messier
DeepSeek AI chatbot running on an iPhone.

China's AI race has never really been short on competition, but it's increasingly looking like a battle over who can charge the least rather than who can build the best model.

DeepSeek has unveiled its latest open-weight AI model, called V4-Flash, alongside a dramatic price reduction that makes it significantly cheaper for developers to use. The company has cut token pricing by 50% and has also decided against introducing a previously announced dynamic pricing system that would have increased costs during periods of heavy demand. The new changes paint a clear picture: DeepSeek appears more interested in winning over developers and expanding its user base than maximizing revenue in the short term.
