The Unusual Origin of Peacock Brown

(Phys.org) —SLAC researchers have demonstrated for the first time how to produce pairs of X-ray laser pulses in slightly different wavelengths, or colors, with finely adjustable intervals between them – ...

(Phys.org) —Many of life's processes rely on light to trigger a chemical change. Photosynthesis, vision, the movement of light-seeking or light-avoiding bacteria, for instance, all exploit photochemistry. ...

Bottles, packaging, furniture, car parts... all made of plastic. Today we find it difficult to imagine our lives without this key material that revolutionized technology over the last century. There is wide-spread optimism ...

If engineers at Stanford have their way, biological research may soon be transformed by a new class of light-emitting probes small enough to be injected into individual cells without harm to the host. Welcome ...

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.

Using the geometric and material properties of a unique nanostructure, Boston College researchers have uncovered a novel photonic effect where surface plasmons interact with light to form "plasmonic halos" ...

Materials belonging to the family of dilute magnetic oxides (DMOs)—an oxide-based variant of the dilute magnetic semiconductors—are good candidates for spintronics applications. This is the object of ...

An international team of scientists using a new X-ray method recorded the internal structure and cell movement inside a living frog embryo in greater detail than ever before.

Spinning-disk confocal microscopy is an optical imaging technique that can be used to generate detailed three-dimensional fluorescence images of living cells and their contents. Although a powerful tool for ...

Most cells exist in a hydrated state and often live suspended in solution. In order to be imaged, cells must generally be frozen or dried, and then stained with substances such as heavy metals. Unfortunately, ...

Andong He saw a phenomenon at work in his breakfast bowl that he couldn't explain. It prompted this question: How does cereal shape influence the way cereals floating in the milk join?

An international collaboration of scientists has discovered a unique crystalizing behavior at the interface between two immiscible liquids that could aid in sustainable energy development.
