A groundbreaking advancement in electromagnetic shielding has been made by a research team led by Dr. Byeongjin Park and Dr. Sang Bok Lee at the Korea Institute of Materials Science (KIMS). They have developed the world’s first ultra-thin film composite material that absorbs over 99% of electromagnetic waves across a wide range of frequency bands, including 5G/6G, WiFi, and autonomous driving radar— all from a single material.

This revolutionary material, measuring less than 0.5 mm thick, features an extraordinary reflectance of under 1% and an impressive absorbance rate of over 99% across three distinct frequency bands. The ability to absorb such a wide spectrum of electromagnetic waves simultaneously is a major breakthrough, addressing a range of technological challenges in electronic devices.

In a recent video update shared by drone pilot and Giga Texas observer Brad Sloan, workers can be seen painting the interior walls of the Boring Company’s much-anticipated underground “Cybertunnel” beneath the 130 Highway at the Austin, Texas factory. Construction on the tunnel, which began in March, is approaching completion, and Elon Musk has previously indicated that the tunnel will be used to transport Cybertrucks from the factory to the outbound lot, where they will then be picked up by hauling trucks for shipping.

Sloan’s video also highlights several other key developments around the Giga Texas facility, including the installation of more glass panels and tests of the water cooling towers intended to support the site’s supercomputing cluster, known as Cortex. These cooling towers are essential for maintaining the optimal performance of the factory’s advanced computing infrastructure.

Scientists from the Rwanda Forestry Authority have identified two types of trees that hold the potential to generate clean electricity, offering a sustainable energy solution for remote communities. This discovery could play a key role in Rwanda’s goal of achieving universal electricity access by 2030.

Despite significant progress in electrification, rural areas in Rwanda continue to face challenges with limited access to power. In response, researchers are exploring ways to produce electricity from biomass derived from sustainably cultivated plants. They are studying the energy potential of various tree species to find alternatives to conventional energy sources.
