Advance uses thought experiments, instead of real data, to expedite learning. Researchers from the UCLA Samueli School of Engineering have unveiled an artificial intelligence-based model for computational imaging and microscopy without training with experimental objects or real data.

In a recent paper published in Nature Machine Intelligence, UCLA’s Volgenau Professor for Engineering Innovation Aydogan Ozcan and his research team introduced a self-supervised AI model nicknamed GedankenNet that learns f...

Holograms increase Solar Energy Yield

Researchers recently developed an innovative technique to capture the unused solar energy that illuminates a solar panel. They created special holograms that can be easily inserted into the solar panel package. This method can increase the amount of solar energy converted by the solar panel over the course of a year by about five percent.

The energy available from sunlight is 10,000 times more than what is needed to supply the world’s energy demands. Sunlight has two main properties that are useful in the design of renewable energy systems. The first is the amount power falling on a fixed area, like the ground or a person’s roof...

Using Artificial Intelligence to generate 3D Holograms in Real-time

hologram projection

Researchers have developed a way to produce holograms almost instantly. The deep learning-based method is so efficient, it could run on a smartphone, they say.

Despite years of hype, virtual reality headsets have yet to topple TV or computer screens as the go-to devices for video viewing. One reason: VR can make users feel sick. Nausea and eyestrain can result because VR creates an illusion of 3D viewing although the user is in fact staring at a fixed-distance 2D display. The solution for better 3D visualization could lie in a 60-year-old technology remade for the digital world: holograms.

Holograms deliver an exceptional representation of 3D world around us. Plus, they’re beautiful. (Go ahead — check out the holographic dove on your Visa card...

Scientists Apply Revolutionary 30 Year-Old Principle and Find Black Holes Could Be Like Holograms

What researchers have done is apply the theory of the holographic principle to black holes. In this way, their mysterious thermodynamic properties have become more understandable: focusing on predicting that these bodies have a great entropy and observing them in terms of quantum mechanics, you can describe them just like a hologram: they have two dimensions, in which gravity disappears, but they reproduce an object in three dimensions.

According to new research, black holes could be like a hologram, where all the information is amassed in a 2D surface able to reproduce a 3D image.

We can all picture that incredible image of a black hole that traveled around the world about a year ago...
