Researchers at the University of California, Berkeley, have developed a method to break a human limit and unlock a color previously unseen by human eyes.

Aptly called “Oz,” the technique activates thousands of retinal cone cells, which triggers the ability to perceive a new color: a “highly saturated blue-green color.” Beyond the cool effect, it could help address visual deficiencies.

Oz represents a new class of experimental platform for vision science and neuroscience, which strives for complete control of the first neural layer to the brain. Dive deeper into this Must-Read.

MUST-READ

👁️ Humans see color never before visible to naked eye with retinal stimulation technique

Unlike traditional color reproduction, the Oz technique does not manipulate the light spectrum emitted to stimulate the retinal cone cells in our eyes.

The methods currently employed trigger an overlap due to the sensitivity of these cells to different wavelengths and intensities of light, restricting the range of colors the eye can perceive.

By focusing on a specific type of cone cell, the Oz technique effectively bypasses the overlap and enables participants to see a new color outside the normal spectrum. And the team overcame the limitations by employing “spatial metamerism.”

🧑‍🚀 International Space Station enters riskiest period, NASA ‘deeply concerned’ over safety

The International Space Station (ISS) has reached “the riskiest period of its existence.”

Cracks aboard the space station have been a long-running concern. Over the years, air leaks have hindered operations, and funny enough, the source of a leak was found thanks to floating tea leaves.

SpaceX CEO Elon Musk recently recommended that NASA deorbit the station sooner. The station “served its purpose,” he said. Could it be the end of its 26 year run? What about the risk that debris poses to the public?

🪖 Fast and mysterious: Italian Pumas appear in Ukraine with no known delivery trail

This is just from Ukraine: Italian-made Puma 6x6 armored personnel carriers (APCs) have entered the battlefield. No one knows how they got there, though.

The wheeled, light-armored vehicle produced by Italian defense consortium Iveco Oto Melara was designed for reconnaissance and fast-assault missions. It can carry a two-man crew and six to eight infantry soldiers.

Though the donor has not been announced or even mentioned, a pattern in past deliveries and logistics may suggest who it is.
