Scientists Shine a Laser Through a Human Head 

It’s the first step toward an inexpensive new medical imager...

For the most part, anyone who wants to see what’s going on inside someone else’s brain has to make a trade-off when it comes to which tools to use. The electroencephalograph (EEG) is cheap and portable, but it can’t read much past the outer layers of the brain, while the alternative, functional magnetic resonance imaging (fMRI), is expensive and the size of a room, but can go deeper. Now, a research group in Glasgow has come up with a mechanism that could one day provide the depth of fMRI using equipment as affordable and portable as an EEG. The technology will rely on something that previously seemed impossible—shining light all the way through a person’s head. more

Magnetocaloric Refrigerator - Runs on magnets instead of harmful gases.
Very few companies have mastered the science of magnetocalorics sufficiently to develop a commercial refrigerator, but perhaps none have also been successful in making the concept “cool” from a marketing standpoint. Now, though, a young academic spinoff company from Darmstadt, Germany is changing the landscape with its Polaris beverage refrigerator. The company is MagnoTherm Solutions GmbH, a pioneering upstart in sustainable cooling. It recently took part in ChangeNOW in Paris, a global event that unites change-makers from around the world to drive positive transformation for our planet. more

A Stratosphere Cell Tower

Starting next year, Tokyo’s SoftBank Corp. will be beaming a prototype 4G and 5G phone and broadband service from the stratosphere to Japanese end users. Floating 20 kilometers above the Earth, the company’s airship-based mast will be using energy-regeneration tech and newly allocated spectrum. And the tech could ultimately pose a real, competitive threat to satellite-based platforms like Starlink. more

Man Is Controls iPad With His Thoughts

You can officially control an Apple device with your thoughts, as long as you have the Stentrode brain implant made by NYC-based Synchron. First announced in May, the capability connects brain-computer interfaces (BCI) to Apple products through a Bluetooth connection. It works with iOS, iPadOS, and visionOS, so that means iPads, iPhones, and the Vision Pro can recognize a BCI just like a keyboard or mouse. Apple designed it to be a standard connection for all implants, including Elon Musk's Neuralink, but Synchron is the first to offer the capability to its patients. more
