A simple arrangement of switchable mirrors can create "holes in time" of almost any length.
By exploiting some exotic acoustic techniques, researchers have built a window that allows the passage of air but not sound
Coat a layer of graphene with chlorophyll and you get a remarkably sensitive light-activated switch, say physicists.
An environmentally-friendly way of making vanillin from the lignin in wood pulp could change the economics of this flavouring industry
Physicists have worked out how to cloak a region of space from the quantum world, thereby shielding it from reality itself
Big, cheap invisibility cloaks are suddenly beginning to emerge thanks to some simple optical short cuts that physicists have discovered
Researchers demonstrate an invisibility cloak that can be scaled to almost any size and say it could be used to hide orbiting satellites
A mirror ball--the most perfect test particle ever placed in orbit--should help Italian scientists measure an exotic effect predicted by general relativity
The A4 digital scanner gathering dust under your desk could find new life as a gigapixel holographic microscope, say Japanese engineers who have constructed one at minimal cost
Atomic force measurements show that the bond between two gold atoms is highly directional and molecular-like, a finding with significant implications for the design and construction of atomic-scale devices
