Retina-inspired sensors for more adaptive visual perception

Posted by in categories: robotics/AI, surveillance

To monitor and navigate real-world environments, machines and robots should be able to gather images and measurements under different background lighting conditions. In recent years, engineers worldwide have thus been trying to develop increasingly advanced sensors, which could be integrated within robots, surveillance systems, or other technologies that can benefit from sensing their surroundings.

Researchers at Hong Kong Polytechnic University, Peking University, Yonsei University and Fudan University have recently created a new sensor that can collect data in various illumination conditions, employing a mechanism that artificially replicates the functioning of the retina in the human eye. This bio-inspired sensor, presented in a paper published in Nature Electronics, was fabricated using phototransistors made of molybdenum disulfide.

“Our research team started the research on five years ago,” Yang Chai, one of the researchers who developed the sensor, told TechXplore. “This emerging device can output light-dependent and history-dependent signals, which enables image integration, weak signal accumulation, spectrum analysis and other complicated image processing functions, integrating the multifunction of sensing, data storage and data processing in a single device.”

Scientists are producing deadly zoonoses on this tiny German island

Posted by in category: biotech/medical

On a small, unassuming German island called Riems lies one of the oldest virus research institutes in the world. And also one of the most dangerous.

The Friedrich Loeffler Institute is closed to the public. To access the island, approved visitors must first cross a small stretch of the Baltic Sea via a dam, which can be closed immediately in case of an outbreak. To enter the facility, they must take a shower and put on protective clothing. Inside, scientists study some of the world’s most deadly viruses, including bird flu, Ebola and mad cow disease.


The German island of Riems is home to some of the most dangerous virology research on the planet.

Gabe Newell: ‘Most of the people talking about metaverse have absolutely no idea what they’re talking about’

Posted by in category: futurism

Valve President calls metaverse a problem that was solved a decade ago.

Gabe Newell, the co-founder and CEO of Valve Corporation, the company that gave us iconic games like Half-Life and Portal, does not believe in the hype around the metaverse.

In an interview with PC Mag, Newell even went on to say “Most of the people who are talking about metaverse have absolutely no idea what they’re talking about”. ## The hype around the Metaverse.
