Medium Access Control (MAC) for Wireless Body Area Network (WBAN): Superframe structure, multiple access technique, taxonomy, and challenges - Human-centric Computing and Information Sciences
Health monitoring using biomedical sensors has witnessed significant attention in recent past due to the evolution of a new research area in sensor network known as Wireless Body Area Networks (WBANs). In WBANs, a number of implantable, wearable, and off-body biomedical sensors are utilized to monitor various vital signs of patient’s body for early detection, and medication of grave diseases. In literature, a number of Medium Access Control (MAC) protocols for WBANs have been suggested for addressing the unique challenges related to reliability, delay, collision and energy in the new research area. The design of MAC protocols is based on multiple access techniques. Understanding the basis of MAC protocol designs for identifying their design objectives in broader perspective, is a quite challenging task. In this context, this paper qualitatively reviews MAC protocols for WBANs. Firstly, 802.15.4 and 802.15.6 based MAC Superframe structures are investigated focusing on design objectives. Secondly, different multiple access techniques such as TDMA, CSMA/CA, Slotted Aloha and Hybrid are explored in terms of design goals. Thirdly, a two-layered taxonomy is presented for MAC protocols. First layer classification is based on multiple access techniques, whereas second layer classification is based on design objectives and characteristics of MAC protocols. Critical and qualitative analysis is carried out for each considered MAC protocol. Comparative study of different MAC protocols is also performed. Finally, some open research challenges in the area are identified with initial research directions.

US20150339658A1 - Method of authentication between a mobile terminal and a processing terminal - Google Patents
A method is provided for authentication between a mobile terminal, located less than a predefined distance from the body of a user, and a processing terminal. The mobile terminal includes an antenna constituting a radio interface suitable for transmitting and receiving radio signals through the body of the user, and the processing terminal is suitable for transmitting and receiving radio signals through the body of the user. The method includes: approaching a user interface of the processing terminal with a portion of the body, triggering an activation of the processing terminal and establishing communication between the processing terminal and the mobile terminal; requesting the entering of a piece of personal authentication data; memorizing the authentication data entered; sending the authentication data through the body; receiving a result of a check of the authentication data carried out by the terminal; and checking the result.

ULTRARAM may be a silly name but it's the holy grail for memory tech and means your PC could hibernate for over 1,000 years
Close your laptop lid and open it 1,000 years later to carry on your Baldur's Gate 3 save as if nothing had happened.
"ULTRARAM is a charge-based memory that stores data by moving electrons into or out of a so-called 'floating gate'. The charge state of the floating gate is read non-destructively by measuring the conductance of an underlying 'channel'. The final component of the memory is the barrier that acts like a 'lock' to retain electrons in the floating gate during data retention. The barrier is unlocked to allow charge to flow when the memory is being written or erased."

The Superconductor Sensation Has Fizzled, and That’s Fine
All of LK-99’s bizarre behavior that hinted at superconductivity—such as its partial levitation over a magnet—can apparently be explained away by odd but distinctly nonsuperconductive properties, such as ferromagnetism, the same structural quirk that allows magnetic fields to permeate iron and reconfigure the metal’s electrons.

Move Over, Silicon; Here Come Quantum Bismuth Chips
Bismuth Telluride Valley doesn't quite have the same ring to it, but a new discovery may mean the end of silicon chips. After decades of using Bi2Te3 for its thermoelectric properties, researchers have discovered new properties of the material that paves the way for bismuth telluride chips constructed to power quantum computers.
