A new radio telescope in Western Australia, known as Australian Square Kilometre Array Pathfinder (ASKAP), has discovered PKS B1740-517 – a galaxy located more than 5 billion light years away. Six of the 36 dishes on the radio telescope captured signals emitted from PKS B1740-517. This discovery demonstrates that ASKAP can detect galaxies and signals that other telescopes … [Read more...]
‘Unstoppable’ New Hacking Device Steals Encryption Keys Out of the Air
A group of researchers from Tel Aviv University and the Israeli research center have produced a new hacking device that can steal encryption keys “out of the air.” The device cannot be stopped by disabling Wi-Fi networks or turning off Bluetooth because the device doesn’t use standard communication methods to steal data. The device uses radio waves emitted from computer … [Read more...]

The router has three settings: wall penetration, balance and pregnant women. The … [Read more...]
Energy-efficient Electric Car: No AM Radio Due to Possible EMI
The BMW i3 Electric Car was the most energy-efficient car sold in the U.S. this year, according to Green Car Reports. However, consumers noticed the car does not offer AM Radio. “AM is not offered due to negative performance influences of the electromagnetic interference of the electric drivetrain. Electric motors cause interference on AM which is why BMW decided to remove … [Read more...]
Defense Contractor to Produce Electromagnetic Aircraft Launch System
General Atomics, a defense contractor in San Diego, Calif., announced it will produce the Electromagnetic Aircraft Launch System (EMALS) and Advanced Arresting Gear (AAG) for the John F. Kennedy aircraft carrier under a contract from the U.S. Navy. The EMALS system uses bursts of electromagnetic energy to launch planes and jets into the air. It takes up less space on ships, … [Read more...]
EMI from Smartphones May Affect Cardiac Devices
Dr. Carsten Lennerz, cardiology resident in Germany, presented results of a study on Monday at the European Heart Rhythm Association (EHRA) Eurospace Cardiostim. “Pacemakers can mistakenly detect electromagnetic interference (EMI) from smartphones as a cardiac signal, causing them to briefly stop working. This leads to a pause in the cardiac rhythm of the pacing dependent … [Read more...]
