May was using a feature on the glasses called Ally, which lets him start video calls with friends and family to get help.
“I called up one of my colleagues, Evelyn, and said, ‘What do you see?’ and she described the environment to me,” said May, chief evangelist at accessible navigation company Goodmaps. “She told me where the tables were and just gave me the lay of the land.”
Envision Glasses are built on the enterprise edition of Google Glass. (Yes, Google Glass is still alive.) Google unveiled these smart glasses back in 2013, then touting them as a way for users to take calls, send texts, snap pictures and look at maps, among other things, right from the headset. But after a limited — and unsuccessful — release, they never hit store shelves.
The world seems to have taken notice of the level of details services like Google Maps offer on an everyday basis. A Twitter account supporting the Ukrainian forces recently shared some images of Russian military establishments that were in public view on Google Maps.
⚡️GOOGLE MAPS ВІДКРИВ ДОСТУП ДО ВІЙСЬКОВИХ ТА СТРАТЕГІЧНИХ ОБ’ЄКТІВ РОСІЇ. Тепер кожен може побачити різноманітні російські пускові установки, шахти міжконтинентальних балістичних ракет, командні пункти та секретні полігони з роздільною здатністю близько до 5 метра на піксель. pic.twitter.com/i75wR8Efwo — Armed Forces 🇺🇦 (@ArmedForcesUkr) April 18, 2022
As the caption reads, Google has opened access to Russian military and strategic facilities. The tweet was probably an attempt at virtue signaling that Google had taken a stance against Russian aggression. However, as a Google spokesperson told The Verge, the information was available in the public domain well before the Ukraine conflict.
Summary: Brain mapping study reveals memory engrams are widely distributed throughout the brain, including among regions not previously realized.

A new study by scientists at The Picower Institute for Learning and Memory at MIT provides the most comprehensive and rigorous evidence yet that the mammalian brain stores a single memory across a widely distributed, functionally connected complex spanning many brain regions, rather than in just one or even a few places.
We’ve seen this funky dual disk polar printer already recently, but [Heinz Loepmeier] has been busy working on it, so here’s an update. The primary focus here is nozzleboss, a blender plugin which enables the surface textures of already sliced objects to be manipulated. The idea is to read in the gcode for the object, and convert it to an internal mesh representation that blender needs in order to function. From there the desired textures can be applied to the surfaces for subsequent stages to operate upon. One trick that nozzleboss can do is to create weight maps to tweak the extrusion flow rate or print velocity value according to the pixel value at the surface — such ‘velocity painting’ can produce some very subtle surface effects on previously featureless faces. Another
trick is to use the same weight maps and simply map colours to blender text blocks which are injected into the gcode at export time. These gcode blocks can be used swap tool heads or extruders, enabling blending of multiple filament colours or types in the same object.
Some nice examples of such printing manipulation can be seen on [Heinz’s] instagram page for the project. So, going back to the hardware again, the first video embedded below shows the ‘dual disk polar printer’ fitted with a crazy five-extruders-into-one-nozzle mixing hotend setup, which should be capable of full CMYK colour mixing and some. The second video below shows an interesting by-product of the wide horizontal motion range of the machine, that the whole printing area can be shifted to a nozzle at the other end of the gantry. This enables a novel way to switch extruders, by just moving the whole bed and print under the nozzle of interest! One final observation — is that of the print surface — it does look rather like they’re printing direct onto a slab of marble, which I think is the first time we’ve seen that.
Interesting printer designs are being worked on a lot these days, here’s a really nice 5-axis prusa i3 hack, and if you want to stay in the cartesian world, but your desktop machine is just too small, then you can always supersize it.
Scientists have developed a new artificial intelligence (AI) technology that models and maps the natural environment in intricate detail. Check out how this could help scientists in their work.
These steps are repeated for each cell type, creating a richer and more complete map of the brain with each run-through.
Working together to build a brain map
Scientists now have the tools to examine the entire brain in very fine detail. There has been considerable effort to coordinate and pool data from brain mapping research labs to create comprehensive brain maps. For example, the U.S. BRAIN Initiative created the BRAIN Initiative Cell Census Network (BICCN) in which my lab participates. Collaborating research groups in the network recently released the most comprehensive map of cell types in the brain’s motor cortex across humans, monkeys and mice.
