Australia is Building a 1,250-Mile Highway for Electric Vehicles
July 27, 2017 04:54 PM - Yale Environment 360

Australia will install 18 electric vehicle fast-charging stations along a nearly 1,250-mile stretch of coastal highway in Queensland, creating one of the world’s longest EV roadways, Reuters reported

The network, which will cost $3 million to build and open within six months, will stretch from Cairns to Coolangatta and west to Toowoomba, running parallel to the Great Barrier Reef. The charging stations will power a vehicle in 30 minutes. Drivers will be able to charge their vehicles for free for at least a year.

Birds sing shorter songs in response to traffic noise

Taylor & Francis Group via EurekAlert!

Birds sing differently in response to traffic noise, which potentially affects their ability to attract mates and defend their territory, according to research published in Bioacoustics. The study found that a species of North American flycatcher sings shorter songs at a lower range of frequencies in response to traffic noise levels. The researchers suggest traffic noise reduction, for example through road closures, is a viable option for mitigating this effect.
