Acoustic cloaking device echoes advances in optical cloaking

Optical cloaking devices that enable light to gracefully slip around a solid object were once strictly in the realm of science fiction. Today they have emerged as an exciting area of study, at least on microscopic scales. ...

Accounting for scale in catalysis

(PhysOrg.com) -- Depicting a catalyst's behavior in the real world just got a lot easier, thanks to scientists in the Institute for Interfacial Catalysis (IIC) at Pacific Northwest National Laboratory. They used complex calculations ...

Researchers probe invisible vacancies in fuel cell materials

(Phys.org) -- Knowing the position of missing oxygen atoms could be the key to cheaper solid oxide fuel cells with longer lifetimes. New microscopy research from the Department of Energy's Oak Ridge National Laboratory is ...

Quantum simulation could help flights run on time

A powerful new form of computing could help scientists design new types of materials for nanoelectronics, allow airlines to solve complex logistical problems to ensure flights run on time, and tackle traffic jams to keep ...

Big cities feed on their hinterlands to sustain growth

Researchers at Linköping University in Sweden call into question an influential theory of the self-reinforcing dynamics of urban growth. Their research, published in Science Advances, shows that big cities feed on their ...

New study sheds light on quake peril for Istanbul

An investigation into a perilous fault that runs south of Istanbul suggests it could unleash two or three big quakes in a series rather than an extremely large one-off event, as some studies have feared.
