[IBM], the corporate as soon as synonymous with all issues computing, [recently] introduced that it’s demonstrated a 2-nanometer (nm) chipmaking course of for the primary time. In a press launch, IBM mentioned the brand new course of would yield some 50 billion transistors on a chip the dimensions of a fingernail.”
New ‘Liquid’ AI Learns Constantly From Its Expertise of the WorldBy Jason Dorrier“For all its comparisons to the human mind, AI nonetheless isn’t very similar to us. Perhaps that’s alright. Within the animal kingdom, brains are available in all sizes and styles. So, in a brand new machine studying method, engineers did away with the human mind and all its lovely complexity—turning as an alternative to the mind of a lowly worm for inspiration. Seems, simplicity has its advantages. The ensuing neural community is environment friendly, clear, and right here’s the kicker: It’s a lifelong learner.”
Seismic ‘Telescope’ Reveals a Titanic, Tree-Like Plume Feeding Earth’s VolcanoesBy Jason Dorrier“Scientists have lengthy theorized that columns of superheated rock—piping sizzling plumes pushing by way of the mantle to the crust above—clarify the Hawaiian islands and different areas like them. The place these columns contact the floor, volcanic hotspots kind and the bottom erupts. …The speculation is outdated, however really observing the mantle plumes feeding these hotspots in any element is pretty new. ‘Theoretically, we all know [plumes] need to exist,’ Harriet Lau, a College of California, Berkeley geophysicist advised Quanta Journal. ‘However they’re simply so exhausting to see seismically.’ Now, nevertheless, in a very hanging instance, a workforce of scientists have accomplished a map of the underworld almost a decade within the making.”
What’s the Origin of Consciousness? World Effort Places Two Prime Theories to the TestBy Shelly Fan“How does consciousness work? A frenemy collaboration is duking it out. Six completely different groups from throughout the globe are uniting in a problem to check our basic theories of consciousness. They don’t agree on the place or how consciousness originates within the mind. However they’re keen to battle it out by way of a good match. For the previous two years—and the following few—the groups agreed to standardize checks to discover the boundaries of consciousness, whereas producing intricate maps of mind activation throughout consciousness.”
