Previous demonstrations of cloaking, where objects are rendered invisible at certain frequencies, have been limited to the microwave regime. Moving us a significant step closer to invisibility in a region that can been seen by humans, a cloaking device has now been demonstrated for a broad range of frequencies in the near-infrared.

Concerns over safety and the inability to control release have hampered progress towards instilling siRNA into mucosal tissue for protection against and treatment of human disease. Nanoparticles made from FDA-approved polymers have now been loaded with large amounts of siRNA and topically applied to vaginal mucosa leading to sustained gene silencing.

Metal–organic frameworks are highly porous materials that are promising for drug release and gas storage. A liquid-phase-epitaxy approach that prevents interpenetration and retains the pore size is now proposed.

Multiferroics offer intriguing opportunities for sensing and information storage applications, although their integration into electronic devices has been difficult owing to a lack of suitable electronic control. Electric modulation of conduction is now achieved for a doped multiferroic, resulting in complete control over the ferroelectric state itself.
