Metamaterials may advance with new femtosecond laser technique
Researchers in applied physics have cleared an important hurdle in the development of advanced materials, called metamaterials, that bend light in unusual ways.
Scientists create first free-standing 3-D cloak
Researchers in the US have, for the first time, cloaked a three-dimensional object standing in free space, bringing the much-talked-about invisibility cloak one step closer to reality.
DNA as invisible ink can reversibly hide patterns
Unveiling malaria's 'invisibility cloak'
The discovery by researchers from the Walter and Eliza Hall Institute of a molecule that is key to malaria's 'invisibility cloak' will help to better understand how the parasite causes disease and escapes from the defenses ...
A breakthrough in superlens development: Cheap, simple lens to let us see a single virus
A superlens would let you see a virus in a drop of blood and open the door to better and cheaper electronics. It might, says Durdu Guney, make ultra-high-resolution microscopes as commonplace as cameras in ...
Researchers transfer the concept of an optical invisibility cloak to sound waves
Progress of metamaterials in nanotechnologies has made the invisibility cloak, a subject of mythology and science fiction, become reality: Light waves can be guided around an object to be hidden, in such a way that this object ...
Invisible computing comes to Asia tech expo
A robotic cook, a colouring book that comes to virtual life and movies that read your mind are some of the innovations on show at a cutting-edge computer technology exhibition in Hong Kong this week.
Hiding objects with a terahertz invisibility cloak
Researchers at Northwestern University have created a new kind of cloaking material that can render objects invisible in the terahertz range.
Researchers create first 3D invisibility cloak
Light speed hurdle to invisibility cloak overcome by undergraduate
(PhysOrg.com) -- An undergraduate student has overcome a major hurdle in the development of invisibility cloaks by adding an optical device into their design that not only remains invisible itself, but also has the ability ...
New invisibility cloak hides objects from human view
For the first time, scientists have devised an invisibility cloak material that hides objects from detection using light that is visible to humans. The new device is a leap forward in cloaking materials, according to a report ...
Smartphones help world's winemakers foil fraudsters
For Charles Pillitteri, the fight against fraudsters began when he discovered fake bottles of his Canadian ice wine in Taiwan in 1998.
Research team develops method to produce large sheets of metamaterials
Using living cells as an 'invisibility cloak'
The quest for better ways of encapsulating medicine so that it can reach diseased parts of the body has led scientists to harness -- for the first time -- living human cells to produce natural capsules with ...
