Photonic Crystal and Nanowire Combo Advances 'Photonic Integration'

APP-Notomi-nanowire-schematic.jpg

While bigger nanowires can improve light confinement and performance, it increases both energy consumption and device footprint -- both of which are considered “fatal” when it comes to integration. Addressing this problem, researchers came up with an approach that involves combining a sub-wavelength nanowire with a photonic crystal platform, which they report this week in the journal APL Photonics.

Making a ‘Beeline’ Past the Blood-Brain Barrier for Drug Delivery

NM253BBB.jpg

Most medicines can’t get through the blood-brain barrier (BBB), a highly selective membrane that separates the circulatory system from the fluid bathing the brain. Certain peptides in animal venoms, however, can navigate across it to inflict damage. Now, researchers are capitalizing on venomous sneak attacks by developing a strategy based on a bee-venom peptide, apamin, to deliver medications to the brain.

UAB Creates Triple-Threat Cancer-Fighting Polymer Capsules for Guided Drug Delivery

Guideddrugdeliverygraphic.png

Chemists have designed triple-threat cancer-fighting polymer capsules for guided drug delivery. They combine three traits: good imaging contrast with low-power ultrasound, stable packaging of the cancer drug doxorubicin, and ability to trigger drug release with low- or higher-power ultrasound.

Researchers Discover a New Type of Memory Effect in Transition Metal Oxides

A new kind of memory effect discovered in two Transition Metal Oxides could carry important repercussions on technology and security. The multi-state nature of the memory effect, whereby more than one piece of information can coexist in the same space, could be harnessed for memory technology. And while deleted computer data can be recovered, at least partially, by talented hackers, the "erase-upon-reading" property of this system could make an invaluable contribution to security technologies.
