Making waves with metamaterials

For Jordan Raney, assistant professor in the Department of Mechanical Engineering and Applied Mechanics, cutting-edge science sometimes involves whacking a rubber disc with a hammer.

Artificial trees capture new bird species on candid camera

An experiment from The Australian National University (ANU) using artificial trees has attracted birds and other wildlife never before seen in a damaged Canberra landscape—catching them on camera at the same time.

Using DNA templates to harness the sun's energy

As the world struggles to meet the increasing demand for energy, coupled with the rising levels of CO2 in the atmosphere from deforestation and the use of fossil fuels, photosynthesis in nature simply cannot keep up with ...

'Meta-mirror' reflects sound waves in any direction

Researchers at Duke University and Aalto University (Finland) have constructed a "meta-mirror" device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking ...

Chemical data mining boosts search for new organic semiconductors

Organic semiconductors are lightweight, flexible and easy to manufacture. But they often fail to meet expectations regarding efficiency and stability. Researchers at the Technical University of Munich (TUM) are now deploying ...

Deep learning for electron microscopy

Finding defects in electron microscopy images takes months. Now, there's a faster way. It's called MENNDL, the Multinode Evolutionary Neural Networks for Deep Learning. It creates artificial neural networks—computational ...
