Researchers at the Vienna University of Technology show that a recently discovered class of materials can be used to create a new kind of solar cell.
Understanding behavioral patterns: Why bird flocks move in unison
Animal flocks, be it honeybees, fish, ants or birds, often move in surprising synchronicity and seemingly make unanimous decisions at a moment's notice, a phenomenon which has remained puzzling to many researchers.
Leading the quest to crack cosmological mysteries
Sometimes a scientist can only laugh in the face of a seemingly insurmountable challenge.
'Building block' of quanutm networks created
(Phys.org)—A proof-of-concept device that could pave the way for on-chip optical quantum networks has been created by a group of researchers from the US.
Pounding particles to create Neptune's water in the lab
We know 'icy' Neptune is partially comprised of water molecules but until now we have had little means to test how water behaves in the extreme conditions that Neptune presents.
Perfect image without metamaterials... and a reprieve for silicon chips (w/ Video)
(PhysOrg.com) -- Since 2000, John Pendry's work on metamaterials has been at the van guard of efforts to create a perfect image - images with perfect resolution that can stem from light being moved in odd ...
