Blue lasers with surface gratings are delivering quantum precision from millimetre footprints. The visible spectrum is an exciting frontier for laser diode technology. Here emerging applications exist ...

To touch grass, venture outdoors and take a break from doom-and-gloom news, what can one do to pass the time without a smartphone? Perhaps they can take a peek into the infinitesimal world outside ...

Try searching for your own micrometeorites by collecting particulates from roofs or drain spouts. Use a magnet to see if any particles are attracted, and discard nonmagnetic ones. Use your microscope ...

Electrons are tiny and constantly in motion. How they behave in a crystal lattice determines key material properties: electrical conductivity, magnetism, or novel quantum effects. Anyone aiming to ...

Investopedia contributors come from a range of backgrounds, and over 25 years there have been thousands of expert writers and editors who have contributed. Thomas J. Brock is a CFA and CPA with more ...

According to conventional wisdom, the compound microscope was invented at the beginning of the seventeenth century and made possible the immediate discovery of cells. This is nonsense. The textbook ...

The brain relies on real-time delivery of oxygen and nutrients through its microvasculature, which threads through neural tissue like electrical wires.

Discover the magic of compounding and why it's important for increasing wealth Robert Kelly is managing director of XTS Energy LLC, and has more than three decades of experience as a business ...

We are at a critical time and supporting science journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen scientific ...

Electron microscopy uses a beam of electrons to illuminate a sample and achieve much higher spatial resolution than light microscopy. Transmission electron microscopy generates an image of the ...

Background Gut bacteria have been implicated in a wide range of health conditions, yet their potential role in preventing and treating muscle-wasting disorders remains largely unexplored. Objective We ...
