• It takes two

  Researchers from the University of Turku, Finland, have demonstrated that Boolean functions can be computed using only two memristors, thus reducing the complexity of circuits incorporating memristors.

  
  

• Coding genetics

  One of the challenges in mathematical biology is to find an underlying code in the structure of DNA. Researchers from the State University of Campinas, Brazil, have demonstrated the existence of error-correcting codes associated with DNA sequences.

  
  

• Diversity through unity

  A single element dual-feed PIFA antenna suitable for wireless diversity and MIMO applications has been created and tested by researchers at the University of Liverpool in the UK.

  
  

• Tapping the light fantastic

  The potential for cost-effective optical power monitoring created on a silicon platform using widely available techniques has been demonstrated by a group of researchers from Canada, the US and the UK.

  
  

• Your flexible friend

  Ferrites are known to be effective for shielding antenna radiation, and researchers in France and India have developed a wearable antenna mounted on a polymer-ferrite sheet.

  
  

• Interview with Akito Chiba

  The first four-Mach-Zehnder type optical modulator to be monolithically integrated on LiNbO3 (LN) for optical 16-level quadrature amplitude modulation (QAM) has been demonstrated by collaborating researchers in Japan. Dr Akito Chiba, a researcher at the National Institute of Information and Communications Technology, tells us more about their achievement.
