  1. These Foldable, High-Throughput Antennas Can Fit Inside A Bag

    Carnegie Technologies and Cubic Corp. this week unveiled separately their ultraportable and lightweight antenna systems that can fold to fit inside a small backpack or suitcase. 

  2. Protecting Implantable Medical Devices From Malware, Side-Channel Attacks

    University of Arizona researchers are trying to shore up implantable medical devices' defenses against cybersecurity threats by developing technologies to better detect malware and thwart side-channel attacks.

  3. Bushwhacking Into Unexplored Transistor Territories

    Since the advent of microelectronics in the mid-20th century, humanity has been on a nonstop sprint to eke more speed, power efficiency, and computational power from the sextillions (1021) of ever more miniaturized transistors that have come to underlie so much of the modern technoscape.

  4. Why Multi-Band Smartphones Can Do Away With Antennas

    Current and future smartphones that combine spectrum from several frequency bands can function without a typical antenna, thanks to a tiny "booster" device that can radiate RF signals from the smartphone itself.

  5. Could Fast Radio Bursts Be Powering Alien Probes?

    The search for extraterrestrial intelligence has looked for many different signs of alien life, from radio broadcasts to laser flashes, without success. However, newly published research suggests that mysterious phenomena called fast radio bursts could be evidence of advanced alien technology.

  6. Karoo’s HERA Radio Telescope Attracts Even More International Funding

    The Hydrogen Epoch of Reionization Array (HERA) radio telescope, located only a few kilometres from the MeerKAT radio telescope, was awarded a grant from the Gordon and Betty Moore Foundation in the US to the value of $5.8M, equivalent to approximately R75 million.

  7. KAUST Develops 5G Signal Optimization Algorithm

    Researchers at Saudi Arabia's King Abdullah University of Science and Technology (KAUST) have developed an efficient wireless signal optimization algorithm that will help realize the full implementation of massive MIMO (multiple input, multiple output) antenna technology for 5th generation (5G) roll-outs.

  8. Cornell Engineers Build Two-Way Software-Defined Radio On A Single Chip

    Researchers at the School of Electrical and Computer Engineering at Cornell University have built a software-defined radio (SDR) transceiver that is capable of transmitting and receiving a radio signal on a single chip, which presents a new way to build wireless communication circuits.
