Scientists develop a brain decoder that can hear your inner thoughts

Researchers at the University of California, Berkeley have invented a brain decoder device that’s able to work out what you’re thinking based on neuron activity inside the brain — essentially, the experimental system means your private inner thoughts are no longer so private. Researchers invited test subjects to read a passage of text out loud and then again in their mind, monitoring brain activity each time to look for linked patterns.

This is about more than spying on your secret thoughts, though — it could be an invaluable method of communication for people who have lost the ability to speak, for whatever reason. Further down the line we could find ourselves controlling smartphones, computers and other devices using nothing but the power of our minds.

“If you’re reading text in a newspaper or a book, you hear a voice in your own head,” the University’s Brian Pasley told New Scientist. “We’re trying to decode the brain activity related to that voice to create a medical prosthesis that can allow someone who is paralysed or locked in to speak.” Pasley and his team based their work around the hypothesis that hearing words in our head causes the same kind of brain activity as hearing them spoken.

The hardware required for this sophisticated decoding is still at the developmental stage and isn’t accurate enough to be used outside of the lab yet, but the signs are promising. “It’s preliminary data, and we’re still working on making it better,” says Pasley. The researchers are also looking into the effects that hearing music has on the brain.

At the moment, the technology only works if the subject has been carefully monitored for some time, and the algorithms underpinning the system can vary from person to person. Still, when an all-encompassing instant mind reading device does appear, remember that you heard it here first.

The Apollo wearable is proven to help you sleep better (and it’s on sale)

Apollo wearable worn during sleep in bed.

Stress, anxiety, and insomnia are all concerning things that just about everyone struggles with at one time or another. Maybe you can sleep, fending off insomnia, but you lack quality sleep and don’t feel rested in the morning. Or, maybe when it’s time to kick back and relax, you just can’t find a way to do so. There are many solutions for these issues, some work, and others don’t, but one unlikely area of support can be found in a modern, smart wearable.

Medicine is the obvious choice, but not everyone prefers to go that route. There is an answer in modern technology or rather a modern wearable device. One such device is the Apollo wearable, which improves sleep and stress relief via touch therapy. According to Apollo Neuro, the company behind the device, which is worn on your ankle, wrist or clipped to your clothing, it sends out waves of vibrations to help your body relax and reduce feelings of stress. It's an interesting new approach to a common problem that has typically been resolved via medicine, therapy, or other more invasive and time-consuming techniques. The way it utilizes those vibrations, uniquely placed and administered, to create a sense of peace, makes us ask, can it really cure what ails us? We’ll dig a little deeper into how it achieves what it does and what methods it’s using to make you feel better.

What comes after Webb? NASA’s next-generation planet-hunting telescope

An illustration shows how NASA's Habitable Worlds Observatory would measure the atmosphere of distant planets.

When it comes to building enormous, complex space telescopes, agencies like NASA have to plan far in advance. Even though the James Webb Space Telescope only launched recently, astronomers are already busy thinking about what will come after Webb — and they've got ambitious plans.

The big plan for the next decades of astronomy research is to find habitable planets, and maybe even to search for signs of life beyond Earth. That's the lofty goal of the Habitable Worlds Observatory, a space telescope currently in the planning phase that is aimed at discovering 25 Earth-like planets around sun-like stars.
