Omniverse Avatar connects the company’s technologies in speech AI, computer vision, natural language understanding, recommendation engines, and simulation technologies, according to the company last month.
Avatars created in the platform are interactive characters with ray-traced 3D graphics that can see, speak, converse on a wide range of subjects, and understand naturally spoken intent, NVIDIA said.

Scientists Discover Another Reason Why EV Batteries Can’t Charge In A Few Minutes
By U.S. Department of Energy | Cleantechnica
Haste makes waste, as the saying goes. Such a maxim may be especially true of batteries, thanks to a new study that seeks to identify the reasons that cause the performance of fast charged lithium-ion batteries to degrade in electric vehicles.

Eagle, Omega Nebula, Trifid, and Lagoon: Four Famous Nebulae
Nebula [ neb-yuh-luh ]: star-forming cloud of gas and dust. Noun, plural neb·u·lae [neb-yuh-lee, -lahy]
These four nebulae are known for their breathtaking beauty: the Eagle Nebula (which contains the Pillars of Creation), the Omega Nebula, the Trifid Nebula, and the Lagoon Nebula. In the 1950s, a team of astronomers made rough distance measurements to some of the stars in these nebulae and were able to infer the existence of the Sagittarius Arm. Their work provided some of the first evidence of our galaxy's spiral structure. In a new study, astronomers have shown that these nebulae are part of a substructure within the arm that is angled differently from the rest of the arm.
A key property of spiral arms is how tightly they wind around a galaxy. This characteristic is measured by the arm's pitch angle. A circle has a pitch angle of 0 degrees, and as the spiral becomes more open, the pitch angle increases. Most models of the Milky Way suggest that the Sagittarius Arm forms a spiral that has a pitch angle of about 12 degrees, but the protruding structure has a pitch angle of nearly 60 degrees.
Similar structures – sometimes called spurs or feathers – are commonly found jutting out of the arms of other spiral galaxies. For decades scientists have wondered whether our Milky Way's spiral arms are also dotted with these structures or if they are relatively smooth.
