Tomonori Totani, an astrobiologist with the University of Tokyo is proposing that the search for life beyond Earth be expanded to the study of space dust. In his paper published in the journal International Journal of Astrobiology, ...
Microplastics are all around us—in the water we drink, the food we eat and the air we breathe. But before researchers can understand the real impact of these particles on health, they need faster and more effective ways ...

A micrometer ( /maɪˈkrɒmɨtər/ US dict: mī·krŏm′·ĭ·tər), sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw used widely for precise measurement of small distances in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers. Micrometers are often, but not always, in the form of calipers.
Colloquially the word micrometer is often shortened to mike /ˈmaɪk/ (US dict: mīk′).
