Swedish researchers have produced the world’s first model car with a roof and battery made from wood-based carbon fibre – a lightweight and renewable alternative to metals and other composites. Remember wood paneled station wagons? Well, wood is back, but this time it’s not for aesthetics – it’s for reducing vehicle weight with renewable materials. Swedish researchers have just produced the world’s first model car with a roof and battery made from wood-based carbon fibre.

Although it’s built on the scale of a toy, the prototype vehicle represents a giant step towards realizing a vision of new lightweight materials from the forest, one of the benefits...

Single photons can quickly modify individual electrons embedded in a semiconductor chip and vice versa, an advance that could be a significant step toward establishing quantum networks in the future. Such networks would transmit qubits from place to place and would offer unbreakable security for the transmitted information. But researchers must first develop ways for qubits that are better at storing information to interact with photons that are better at transporting it, a task achieved in conventional networks by electro-optic modulators that use electronic signals to modulate properties of light.

A/Prof Edo Waks et al have struck upon an interface between photons and single electrons t...
