Quantum diffraction at a breath of nothing

Physicists build stable diffraction structure in atomically thin graphene

27-Aug-2015

Quantum physics tell us that even massive particles can behave like waves, as if they could be in several places at once. This phenomenon is typically proven in the diffraction of a matter wave at a grating. In a European collaboration, researchers carried this idea to the extreme and observed ...

Sperm navigation in 3D

21-Aug-2015

Scientists from the Center of Advanced European Studies and Research (caesar), an Institute of the Max Planck Society, discovered the principles of how sea urchin sperm navigate in their natural three-dimensional environment. Using photonic techniques, the scientists created chemical “landscapes” ...

From fluids to flames, research on the space station is helping advance technology

21-Aug-2015

A study explored the finer points of fluid dynamics, something that is experienced across the planet, but cannot quite be studied as carefully on Earth. A phenomenon called Marangoni convection is one of the fundamental principles of liquid motion and is revealed much more clearly in ...

Finding biomarkers for early lung cancer diagnosis

20-Aug-2015

Lung cancer patients are often diagnosed only when their disease is already at an advanced stage and hard to treat. Researchers at the West Coast Metabolomics Center at UC Davis are trying to change that, by identifying biomarkers that could be the basis of early tests for lung cancer. Lung ...
