Scientific education through films?
Magic swords, wands, cauldrons and cloaks of invisibility do not exist in reality. In contrast, it is possible that scenarios like crashed aircrafts looming out of the mists of an alien planet, patients being snatched from the jaws of death by a risky medical breakthrough, or smug murderers who are betrayed by a few molecules left at the scene of crime are part of our current or future reality.

Beyond good vibrations: New insights into metamaterial magic
Metamaterials have amazing potential--think invisibility cloaks and perfect lenses--but they are more likely to be found in a Harry Potter novel than a lab. To help bring them closer to reality, Michigan Technological University's Elena Semouchkina has gone back to basics and demonstrated that the fundamental physics of metamaterials is more complex than scientists once thought.

Dielectric metamaterial is dynamically tuned by light
Researchers at Duke University have built the first metal-free, dynamically tunable metamaterial for controlling electromagnetic waves. The approach could form the basis for technologies ranging from improved security scanners to new types of visual displays.

UC Berkeley scientists have for the first time engineered 3-D bulk materials that can reverse the natural direction of visible and near-infrared light, a development that could help form the basis for higher resolution optical imaging, nanocircuits for high-powered computers, and, to the delight of science-fiction and fantasy buffs, cloaking devices that could render objects invisible to the human eye. (2008-08-11)

Better mastery of heat flow leads to next-generation thermal cloaks
The idea of a thermal cloak, which is designed to hide heated objects without distorting the temperature outside, has long since fascinated scientists. Materials for such cloaks would need to offer zero thermal conductivity to help camouflage the heat. Now, Liujun Xu and colleagues from Fudan University, Shanghai, China, have explored a new mechanism for designing such materials, in a paper published in EPJ B. These findings could have implications for manipulating the transfer of thermal energy as a way to ultimately reduce heat waste. (2017-12-04)

Guiding sound waves through a maze
Researchers at TU Wien are developing methods for manipulating waves in a targeted manner, so that they can move forward with almost no restriction.

New Lancaster study 'reimagines infertility'
New research from Lancaster University has identified the 'invisible infertile', a group of marginalized people missing from survey data sources because they do not fit neatly into popular notions of who is at risk of infertility. Around the world, the 'invisible infertile' includes racial and ethnic minorities, those with limited economic resources, those who do not have access to affordable healthcare, the LGBTQ community, persons with disabilities, and more often men than women.

Extremely small magnetic nanostructures with invisibility cloak imaged
In novel concepts of magnetic data storage, it is intended to send small magnetic bits back and forth in a chip structure, store them densely packed and read them out later. The magnetic stray field generates problems when trying to generate particularly tiny bits. Now, researchers were able to put an 'invisibility cloak' over the magnetic structures. In this fashion, the magnetic stray field can be reduced in a fashion allowing for small yet mobile bits. (2018-10-18)
