Revolutionizing Connectivity: Researchers Develop Game-Changing 3D Processors

University of Florida / SciTechDaily

Researchers at the University of Florida have developed a new technique using semiconductor technology to produce processors that greatly improve the efficiency of transmitting large volumes of data worldwide. The innovation, featured on the current cover of the journal Nature Electronics, is poised to transform the landscape of wireless communication at a time when advances in AI are dramatically increasing demand.

Traditionally, wireless communication has relied on planar processors, which, while effective, are limited by their two-dimensional structure to operate within a limited portion of electromagnetic spectrum. The UF-designed approach leverages the power of semiconductor technology to propel wireless communication into a new dimension – quite literally.

Researchers have successfully transitioned from planar to three-dimensional processors, ushering in a new era of compactness and efficiency in data transmission.

How Tiny Lidar Tech is Redefining High-Resolution 3D Mapping

By OPTICA – SciTechDaily

Compact, low-power system opens doors for photon-efficient drone and satellite-based environmental monitoring and mapping.

Researchers have developed a compact and lightweight single-photon airborne lidar system that can acquire high-resolution 3D images with a low-power laser. This advance could make single-photon lidar practical for air and space applications such as environmental monitoring, 3D terrain mapping and object identification.

Single-photon lidar uses single-photon detection techniques to measure the time it takes laser pulses to travel to objects and back. It is particularly useful for airborne applications because it enables highly accurate 3D mapping of terrain and objects even in challenging environments such as dense vegetation or urban areas.

Technological Advancements : “Using single-photon lidar technology on resource-limited drones or satellites requires shrinking the entire system and reducing its energy…Read more here.

Space Age Security: How Satellites Could Extend Quantum Encryption Globally

Technical University of Munich (TUM) / SciTechDaily

Quantum cryptography enables secure communication over large distances… How can we guarantee that data sent over the internet is only accessible to its intended recipient? Currently, our data is secured using encryption methods based on the premise that factoring large numbers is a complex task. However, as quantum computing advances, these encryption techniques may become vulnerable and potentially ineffective in the future.

Encryption by means of physical laws… Tobias Vogl, a professor of Quantum Communication Systems Engineering, is working on an encryption process that relies on principles of physics. “Security will be based on the information being encoded into individual light particles and then transmitted. The laws of physics do not permit this information to be extracted or copied. When the information is intercepted, the light particles change their characteristics. Because we can measure these state changes, any attempt to intercept the transmitted data will be recognized immediately, regardless of future advances in technology,” says Tobias Vogl.

The big challenge in so-called quantum cryptography lies in the transmission of data over…Read more here.

Back From the Brink: NASA’s Voyager 1 Restores Data Transmission After 5 Months

By Jet Propulsion Laboratory – SciTechDaily

NASA’s Voyager 1 spacecraft has begun transmitting usable engineering data for the first time since November after a chip failure in one of its onboard computers halted data transmission.

For the first time since November 2023, NASA’s Voyager 1 spacecraft is returning usable data about the health and status of its onboard engineering systems. The next step is to enable the spacecraft to begin returning science data again. The probe and its twin, Voyager 2, are the only spacecraft to ever fly in interstellar space (the space between stars).

Voyager 1 stopped sending readable science and engineering data back to Earth on November 14, 2023, even though mission controllers could tell the spacecraft was still receiving their commands and otherwise operating normally. In March, the Voyager engineering team at NASA’s Jet Propulsion Laboratory in Southern California confirmed that the issue was tied to one of the spacecraft’s three onboard computers, called the flight data subsystem (FDS). The FDS is responsible for…Read more here.
