With the plethora of mouse alternatives available or in development you'd be forgiven for thinking the humble computer mouse was some kind of torturous device inflicted upon computer users. But despite challengers such as the trackball, theWOW-PEN Joy, the ErgoSlider Plus, the Orbita Mouse and the AirMouse – just to name a few – the mouse has maintained its dominance while remaining largely unchanged since its unveiling in 1968.

Map provides near-real-time updates on Japan aftershocks
Almost incomprehensible as the devastation from last Friday's earthquake and tsunami in Japan has been, scientists warn that more aftershocks are on their way. In order to get all the information on current seismic activity in one place, researchers at Texas Tech University's Center for Geospatial Technologies have developed an online, publicly-accessible world map that displays data on disturbances worldwide, almost as soon as they have occurred.

Researchers develop first molecular piston capable of self-assembly
Just like a regular-sized device requires a regular-sized motor to operate, a nanodevice likewise requires a molecular-scale motor. In some cases, that motor takes the form of a piston, and building a piston that's just a few nanometers long ... well, it's pretty hard. It can and has been done, but it's an extremely fiddly process.
