Hubble tells a tale of galactic collisions
(Phys.org) —When we look into the distant cosmos, the great majority of the objects we see are galaxies: immense gatherings of stars, planets, gas, dust, and dark matter, showing up in all kind of shapes. ...
Pink diamond 'behaviour' solved but colour still a mystery
UWA scientists have explained the photochromic behaviour of the pink diamond in an attempt to uncover why they possess their pink colouration.
Arctic study sheds light on tree-ring divergence problem
Changes in tree-ring density in the Arctic may be evidence of changes in light intensity during the trees' growth, according to a new study by San Francisco State University researcher Alexander Stine.
Atomic-scale investigations solve key puzzle of LED efficiency
(Phys.org) —From the high-resolution glow of flat screen televisions to light bulbs that last for years, light-emitting diodes (LEDs) continue to transform technology. The celebrated efficiency and versatility ...
