UCLA researchers create exceptionally strong and lightweight new metal

Magnesium infused with dense silicon carbide nanoparticles could be used for airplanes, cars, mobile electronics and more

A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has created a super-strong yet light structural metal with extremely high specific strength and modulus, or stiffness-to-weight ratio. The new metal is composed of magnesium infused with a dense and even dispersal of ceramic silicon carbide nanoparticles. It could be used to make lighter airplanes, spacecraft, and cars, helping to improve fuel efficiency, as well as in mobile electronics and biomedical devices. (more…)

How Australia got the hump with one million feral camels

A new study by a University of Exeter researcher has shed light on how an estimated one million-strong population of wild camels thriving in Australia’s remote outback have become reviled as pests and culled on a large scale.

Sarah Crowley, of the Environment and Sustainability Institute at the University of Exeter’s Penryn Campus, explored the history of the camel in Australia, from their historic role helping to create the country’s infrastructure through to their current status as unwelcome “invader.”

The deserts of the Australian outback are a notoriously inhospitable environment where few species can survive. But the dromedary camel (Camelus dromedarius) prospers where others perish, eating 80% of native plant species and obtaining much of their water through ingesting this vegetation. (more…)
