Metal oxides hold the key to cheap, green energy

Harnessing the energy of sunlight can be as simple as tuning the optical and electronic properties of metal oxides at the atomic level by making an artificial crystal or super-lattice 'sandwich' says a Binghamton University ...

Hong Kong light pollution 'one of world's worst'

Hong Kong is one of the world's worst cities for light pollution with night skies around 1,000 times brighter than globally accepted levels, researchers said Wednesday ahead of this year's Earth Hour event.

Inexpensive paper sensor accurately IDs pathogenic bacteria

Bacterial infections are the leading cause of disease and death worldwide; an ongoing public health problem exacerbated by slow or inaccurate diagnostics. Now NIBIB-funded scientists have engineered an inexpensive, paper-based ...

Creating custom light using 2-D materials

Finding new semiconductor materials that emit light is essential for developing a wide range of electronic devices. But making artificial structures that emit light tailored to our specific needs is an even more attractive ...

Willie wagtails: The werewolves of the bird world

"A poet is a nightingale who sits in darkness and sings to cheer its own solitude with sweet sounds; his auditors are as men entranced by the melody of an unseen musician, who feel that they are moved and softened, yet know ...

Pulses driven by artificial intelligence tame quantum systems

It's easy to control the trajectory of a basketball: Just apply mechanical force coupled with human skill. But controlling the movement of quantum systems such as atoms and electrons is much more challenging, as these minuscule ...
