Researchers from Seoul National University College of Engineering announced they have developed an optical design technology that dramatically reduces the volume of cameras with a folded lens system utilizing “metasurfaces,” a next-generation nano-optical device.

By arranging metasurfaces on the so that light can be reflected and moved around in the glass substrate in a folded manner, the researchers have realized a with a thickness of 0.7mm, which is much thinner than existing refractive lens systems. The research was published on Oct. 30 in the journal Science Advances.

Traditional cameras are designed to stack multiple glass lenses to refract light when capturing images. While this structure provided excellent high-quality images, the thickness of each lens and the wide spacing between lenses increased the overall bulk of the camera, making it difficult to apply to devices that require ultra-compact cameras, such as virtual and augmented reality (VR-AR) devices, smartphones, endoscopes, drones, and more.

A study found that male worms’ brains can activate conflicting memories, but behavior is driven by the more beneficial one. This research sheds light on how brains prioritize information, offering insights into conditions like PTSD.

A new study by UCL researchers reveals that two conflicting memories can simultaneously be activated in a worm’s brain, even though only one memory directly influences the animal’s behavior.

In the paper published in Current Biology, the researchers showed how an animal’s sex drive can at times outweigh the need to eat when determining behavior, as they investigated what happens when a worm smells an odor that has been linked to both good experiences (mating) and bad experiences (starvation).

DGIST and UNIST researchers have discovered a new quantum state, the exciton-Floquet synthesis state, enabling real-time quantum information control in two-dimensional semiconductors.

A research team led by Professor Jaedong Lee from the Department of Chemical Physics at DGIST (President Kunwoo Lee) has unveiled a groundbreaking quantum state and an innovative mechanism for extracting and manipulating quantum information through exciton and Floquet states.

Collaborating with Professor Noejung Park from UNIST’s Department of Physics (President Chongrae Park), the team has, for the first time, demonstrated the formation and synthesis process of exciton and Floquet states, which arise from light-matter interactions in two-dimensional semiconductors. This study captures quantum information in real-time as it unfolds through entanglement, offering valuable insights into the exciton formation process in these materials, thereby advancing quantum information technology.

CHANDLER, Ariz. – The radiation-tolerant RTG4 field-programmable gate arrays (FPGAs) with lead-free flip-chip bumps from Microchip Technology Inc. in Chandler, Ariz., have earned the Qualified Manufacturers List (QML) Class V status from the U.S. Defense Logistics Agency (DLA).

These radiation-tolerant FPGAs are for critical space programs. QML Class V is the highest level of qualification for space components for human-rated, deep-space, and national security space programs.

RTG4 FPGAs offer more than 150,000 logic elements, and come in flip-chip package construction where flip-chip bumps connect the silicon die and the package substrate for extended the longevity.

GE Research has proposed transformational material solutions to potentially enable a gas turbine blade alloy-coating system capable of operating at a turbine inlet temperature of 1800 °C for more than 30,000 hours. GE aims to develop a niobium (Nb)-based alloy that can operate at 1,300 °C (2372 °F), coating system consisting of a novel oxidation resistant bond coat compatible with the new Nb-based alloy, and thermal barrier coating for improved durability that can operate at 1700 °C (3092 °F) and a scalable manufacturing process for producing internally cooled gas turbine blades with the new alloy. Application of the new technologies to existing combined cycle gas turbines in the U.S. could increase the thermal efficiency by approximately 7%.

The recipient of the world’s first Neuralink brain-chip transplant is able to control a computer mouse by thinking, the tech startup’s founder Elon Musk announced this week.

“Progress is good, and the patient seems to have made a full recovery, with no ill effects that we are aware of,” Reuters reported that Musk said in an X Spaces event on Monday. “Patient is able to move a mouse around the screen by just thinking.”

Musk added that Neuralink was trying to get the patient to click the mouse as much as possible, Reuters reported.
