Researchers report quantum-limit-approaching chemical sensing chip

University at Buffalo researchers are reporting an advancement of a chemical sensing chip that could lead to handheld devices that detect trace chemicals—everything from illicit drugs to pollution—as quickly as a breathalyzer ...

Nanoscale machines convert light into work

Researchers have developed a tiny new machine that converts laser light into work. These optically powered machines self-assemble and could be used for nanoscale manipulation of tiny cargo for applications such as nanofluidics ...

New method allows precise gene control by light

A novel optical switch makes it possible to precisely control the lifespan of genetic copies. These are used by the cell as building instructions for the production of proteins. The method was developed by researchers from ...

Flipping light on-off turns bacteria into chemical factories

Researchers at Princeton University have created a new and improved way to more precisely control genetically engineered bacteria: by simply switching the lights on and off. Working in E. coli, the workhorse organism for ...

Physicists nudge atoms within less than a trillionth of a second

Scientists from Regensburg and Zurich have found a fascinating way to push an atom with controlled forces so quickly that they can choreograph the motion of a single molecule within less than a trillionth of a second. The ...

Researchers create nanoclusters that mimic biomolecules

Biological systems come in all shapes, sizes and structures. Some of these structures, such as those found in DNA, RNA and proteins, are formed through complex molecular interactions that are not easily duplicated by inorganic ...
