Cooling with light

ETH researchers have cooled a nanoparticle to a record low temperature, thanks to a sophisticated experimental set-up that uses scattered laser light for cooling. Until now, no one has ever cooled a nanoparticle to such ...

Image: Hubble's cosmic holiday wreath

This festive NASA Hubble Space Telescope image resembles a holiday wreath made of sparkling lights. The bright southern hemisphere star RS Puppis, at the center of the image, is swaddled in a gossamer cocoon of reflective ...

Researchers explore new chapter of physics

Interactions between light and matter are a fundamental unit of modern physics, but recently researchers have started to look beyond the standard textbook interactions.

'Switchable' smart windows reduce energy consumption significantly

Smart windows that act as blinds in the summer and let all the sunlight through in the winter. That's the idea of the reflective windows Hitesh Khandelwal developed during his doctoral research at TU/e, that are able to reflect ...

Mimicking bug eyes could brighten reflective signs and clothes

That bright, reflective coating used on road signs, bicycles and clothing are important safety measures at night. They help drivers get to their destinations while avoiding bicyclists and pedestrians in low-light conditions. ...

Image: Hubble's diamond in the dust

Surrounded by an envelope of dust, the subject of this NASA/ESA Hubble Space Telescope image is a young forming star known as HBC 1. The star is in an immature and adolescent phase of life, while most of a sun-like star's ...
