Sebuah proyek praktis baru menunjukkan cara membuat pemancar dan penerima radio sederhana menggunakan barang-barang rumah tangga umum seperti aluminium foil.

Panduan ini menjelaskan bahwa sinyal radio tetap menjadi pusat teknologi sehari-hari, mulai dari radio mobil dan menara seluler hingga koneksi GPS, Wi-Fi, dan Bluetooth. Panduan ini mencatat bahwa apa yang disebut sebagai Zaman Keemasan Radio tidak benar-benar berakhir pada tahun 1950-an karena televisi dan layanan nirkabel modern masih mengandalkan gelombang yang sama.

MIT builds terahertz microscope to observe quantum motions in superconductors

Physicists at MIT have developed a new microscope using terahertz light to directly observe hidden quantum vibrations inside a superconducting material for the first time. The device compresses terahertz light to overcome its wavelength limitations, revealing frictionless electron flows in BSCCO. This breakthrough could advance understanding of superconductivity and terahertz-based communications.

Space weather may have blurred SETI's search for alien signals

Researchers at the SETI Institute suggest that solar wind and plasma from stars could distort radio signals from distant intelligent life, making them harder to detect. This means past searches may have overlooked potential evidence by focusing on narrowband signals. Adjusting detection methods could improve future chances of discovery.

China’s ‘land aircraft carrier’ charges flying drone with microwave beam

Minggu, 19 April 2026 Dilaporkan oleh AI

A team from Xidian University has developed a car-mounted microwave wireless power system that kept fixed-wing drones airborne for up to 3.1 hours. The system uses GPS positioning, dynamic tracking, and onboard flight controls to maintain alignment between the emitter and drone during flight. The findings were published on March 25 in the peer-reviewed journal Aeronautical Science & Technology.

NYU physicists create sound-levitated time crystal breaking Newton's third law

Physicists at New York University have developed a new type of time crystal using sound waves to suspend tiny styrofoam beads, resulting in nonreciprocal interactions that defy Newton's third law of motion. The compact, visible system oscillates in a steady rhythm and was detailed in Physical Review Letters. Researchers suggest potential applications in quantum computing and insights into biological rhythms.

New light-based sensor detects early cancer biomarkers in blood

Selasa, 17 Februari 2026 Dilaporkan oleh AI

Scientists have developed a light-based sensor that can identify tiny amounts of cancer biomarkers in blood samples, potentially enabling earlier detection than traditional scans. The technology combines DNA nanostructures, CRISPR, and quantum dots to produce a clear signal from just a few molecules. Tests on lung cancer patient serum showed promising results at sub-attomolar levels.

Researchers propose quantum method for messaging into past

Physicists at MIT have developed a theoretical technique inspired by the film Interstellar to send messages backwards in time using quantum entanglement. The approach mimics closed time-like curves and surprisingly improves communication through noisy channels. While actual time travel remains impossible, the idea could enhance conventional systems.
