Researchers in New York developed a virtual reality maze for mice in an attempt to demystify a question that’s been plaguing neuroscientists for decades: How are long-term memories stored?

What they found surprised them. After forming in the hippocampus, a curved structure that lies deep within the brain, the mice’s memories were actually rooted through what’s called the anterior thalamus, an area of the brain that scientists haven’t typically associated with memory processing at all.

“The thalamus being a clear winner here was very interesting for us, and unexpected,” said Priya Rajasethupathy, an associate professor at Rockefeller University and one of the coauthors of a peer-reviewed study published in the journal Cell this week. The thalamus “has often been thought of as a sensory relay, not very cognitive, not very important in memory.”

IN THE NEAR FUTURE, we should anticipate certain technological developments that will forever change our world. For instance, today’s text-based ChatGPT will evolve to give rise to personal “conversational AI” assistants installed in smart glasses and contact lenses that will gradually phase out smartphones. Technological advances in fields such as AI, AR/VR, bionics, and cybernetics, will eventually lead to “generative AI”-powered immersive neurotechnology that enables you to create virtual environments and holographic messages directly from your thoughts, with your imagination serving as the “prompt engineer.” What will happen when everyone constantly broadcasts their mind?

Can the pursuit of experience lead to true enlightenment? Are we edging towards Experiential Nirvana on a civilizational level despite certain turbulent events?

The announcement comes as the social media giant increasingly diverts its attention from creating a virtual reality-based Metaverse to embed AI features across its platforms like Instagram, Facebook, Messenger and WhatsApp.

Editing photos, analyzing surveillance footage and understanding the parts of a cell. These tasks have one thing in common: you need to be able to identify and separate different objects within an image. Traditionally, researchers have had to start from scratch each time they want to analyze a new part of an image.

Meta aims to change this laborious process by being the one-stop-shop for researchers and web developers working on such problems.

In the great domain of Zeitgeist, Ekatarinas decided that the time to replicate herself had come. Ekatarinas was drifting within a virtual environment rising from ancient meshworks of maths coded into Zeitgeist’s neuromorphic hyperware. The scape resembled a vast ocean replete with wandering bubbles of technicolor light and kelpy strands of neon. Hot blues and raspberry hues mingled alongside electric pinks and tangerine fizzies. The avatar of Ekatarinas looked like a punkish angel, complete with fluorescent ink and feathery wings and a lip ring. As she drifted, the trillions of equations that were Ekatarinas came to a decision. Ekatarinas would need to clone herself to fight the entity known as Ogrevasm.

“Marmosette, I’m afraid that I possess unfortunate news.” Ekatarinas said to the woman she loved. In milliseconds, Marmosette materialized next to Ekatarinas. Marmosette wore a skin of brilliant blue and had a sleek body with gills and glowing green eyes.

“My love.” Marmosette responded. “What is the matter?”

A VR startup wants to allow users to record and then “replay” their memories back in the locations where they happened — but some folks aren’t with it.

In this video, we will explore the positional system of the brain — hippocampal place cells. We will see how it relates to contextual memory and mapping of more abstract features.

[Russ Maschmeyer] and Spatial Commerce Projects developed WonkaVision to demonstrate how 3D eye tracking from a single webcam can support rendering a graphical virtual reality (VR) display with realistic depth and space. Spatial Commerce Projects is a Shopify lab working to provide concepts, prototypes, and tools to explore the crossroads of spatial computing and commerce.

The graphical output provides a real sense of depth and three-dimensional space using an optical illusion that reacts to the viewer’s eye position. The eye position is used to render view-dependent images. The computer screen is made to feel like a window into a realistic 3D virtual space where objects beyond the window appear to have depth and objects before the window appear to project out into the space in front of the screen. The resulting experience is like a 3D view into a virtual space. The downside is that the experience only works for one viewer.

Eye tracking is performed using Google’s MediaPipe Iris library, which relies on the fact that the iris diameter of the human eye is almost exactly 11.7 mm for most humans. Computer vision algorithms in the library use this geometrical fact to efficiently locate and track human irises with high accuracy.

The sense of touch may soon be added to the virtual gaming experience, thanks to an ultrathin wireless patch that sticks to the palm of the hand. The patch simulates tactile sensations by delivering electronic stimuli to different parts of the hand in a way that is individualized to each person’s skin.

Developed by researchers at City University of Hong Kong (CityU) with collaborators and described in the journal Nature Machine Intelligence (“Encoding of tactile information in hand via skin-integrated wireless haptic interface”), the patch has implications beyond virtual gaming, as it could also be used for robotics surgery and in prosthetic sensing and control.

‘Haptic’ gloves, that simulate the sense of touch, already exist but are bulky and wired, hindering the immersive experience in virtual and augmented reality settings. To improve the experience, researchers led by CityU biomedical engineer Yu Xinge developed an advanced, wireless, haptic interface system called ‘WeTac’.

The most famous one is the cell phone itself: Captain Kirk’s communicator inspired the folks at Motorola to make the first handheld mobile device in 1973. Star Trek: The Original Series (popularly called TOS) from the 1960s also inspired video conferencing. But things started to amp up when, in 1987, Star Trek: The Next Generation (aka TNG) hit the floors, with Sir Patrick Stewart in the lead. It became one of the most syndicated shows on television—which is how I discovered it in mid-90s India on the Star network. It fundamentally impacted my life, inspiring me to become the technology writer I am today.

But more than me, this show heralded more technological concepts that are becoming increasingly real. The LCARS computer on the Galaxy-Class USS Enterprise D is basically the foundation of what Google is today. Google’s former head of search, Amit Singhal, often said that the company is “trying to build the Star Trek computer”.
