A new way to create realistic 3D shapes using generative AI

Creating realistic 3D models for applications like virtual reality, filmmaking, and engineering design can be a cumbersome process requiring lots of manual trial and error.

While generative artificial intelligence models for images can streamline artistic processes by enabling creators to produce lifelike 2D images from text prompts, these models are not designed to generate 3D shapes. To bridge the gap, a recently developed technique called Score Distillation leverages 2D image generation models to create 3D shapes, but its output often ends up blurry or cartoonish.

MIT researchers explored the relationships and differences between the algorithms used to generate 2D images and 3D shapes, identifying the root cause of lower-quality 3D models. From there, they crafted a simple fix to Score Distillation, which enables the generation of sharp, high-quality 3D shapes that are closer in quality to the best model-generated 2D images.

A new AI method enables the generation of sharp, high-quality 3D shapes that are closer to the quality of the best 2D image models. Previous approaches typically generated blurry or cartoonish 3D shapes.

10-Year-Old Indian-British Boy Scores IQ Higher Than Einstein And Hawking

Krish, who lives in Hounslow, West London, is not only academically gifted but also excels in music, having won awards as a pianist. The 10-year-old genius has also been inducted into the prestigious Trinity College of Music’s “Hall of Fame” for completing four grades in just six months. He currently holds a grade 7 piano certification, demonstrating his exceptional musical prowess.

Krish’s impressive resume includes winning several musical competitions in West London, where he outshone contestants up to four years his senior. What’s even more impressive is his ability to recite complex instrumentals from memory, without needing sheet music. His parents attest that he can recall entire songs on the piano using only his exceptional memory.

He said, “I don’t get nervous to perform my music at these competitions because I know that I’m not going to mess up.”

Cyanobacterial circadian clock uses an AM radio-like mechanism to control cellular processes

Cyanobacteria, an ancient lineage of bacteria that perform photosynthesis, have been found to regulate their genes using the same physics principle used in AM radio transmission.

New research published in Current Biology has found that cyanobacteria use variations in the amplitude (strength) of a pulse to convey information in single cells. The finding sheds light on how biological rhythms work together to regulate cellular processes.

In AM (amplitude modulation) radio, a wave with constant strength and frequency—called a carrier wave—is generated from the oscillation of an electric current. The audio signal, which contains the information (such as music or speech) to transmit, is superimposed onto the carrier wave. This is done by varying the amplitude of the carrier wave in accordance with the frequency of the .
