When imaging at the single-molecule level, small irregularities known as heterogeneities become apparent – features that are lost in higher-scale, so-called ensemble imaging. At the same time, it has until recently been ...
(Phys.org) —While two-photon interference is an important way of entangling independent identical photons, it does not handle different-color photons with the same aplomb. Recently, scientists at the University of Science ...
(Phys.org) —Photoacoustic imaging is a hybrid biomedical imaging modality, based on the photoacoustic effect, in which non-ionizing laser pulses are delivered into biological tissues. (More specifically, in the photoacoustic ...
Fluid dynamics – a subset of the area of physics known as fluid mechanics – is concerned with the motion, or flow, of liquids and gases. Within fluid dynamics, a vortex is a region within a fluid where the flow is essentially ...
(Phys.org) —Miniaturized bioelectronic probes stand to transform biology and medicine by allowing measurement of intracellular components in vivo. Recently, scientists at Harvard University and Peking University designed, ...
(Phys.org) —The prospect of integrated living organisms into a non-living substrate has long held a compelling appeal for those investigating active matter – the study of a type of easily-deformable out of equilibrium ...

(Phys.org) —Evolution is a process that takes place over long periods of time over which genetics and ecology may interact, producing novel phenotypic traits. Researchers previously found that after roughly 31,500 generations ...
(Phys.org) —A key feature of certain chemicals is their ability to bind to other molecules – a property that emerged through evolution – but current chemical theory lacks the ability to design binders from first principles. ...
(Phys.org) —Proteins accomplish something rather amazing: A protein can have many functions, with a given function being determined by the way they fold into a specific three-dimensional geometry, or conformations. Moreover, ...
(Phys.org) —In the world of biomedical science, optical microscopy rules – and nonlinear optical microscopy, which uses ultrashort pulse lasers as the illumination source, allows researchers to glean much greater detail ...
