Back in the old days, when doctors looked for tumors, exploratory surgery was the only option. Today they use CAT scans, x-rays, ultrasound, and other non-intrusive methods for checking out what lies beneath the skin’s surface. But how do we determine what is beneath the Earth’s surface? Invasive surgery on the Earth is just as dated as doctors’ old methods of finding tumors, if you ask Eric Miller, associate professor of electrical and computer engineering at Northeastern University. If we humans can rely on CAT scans to form three-dimensional computer models of our insides, surely “CAT scans for the Earth" can be valuable in finding contaminants such as nuclear waste, to replace drilling and other harmful methods. Miller and his team, with funding from the Department of Energy, are busily toiling away on this very kind of environmental remediation and monitoring.
For much of the last half of the last century, waste was disposed of in less-than-careful ways. This waste was generated from the buildup of the countrys nuclear stockpile. In many locations, there’s a question about just what is in the earth and how it’s moving – a question that can be answered by digging up large tracks of land. But Miller says that not only is digging not economically feasible, it can also be dangerous if contaminants are exposed and not treated properly.
“One of the legacies of the Cold War is the proliferation of buried chemical and radioactive waste on the grounds of many Department of Energy labs,” says Miller. “While people know roughly where material is buried, it is often the case that detailed records are not available. Working with the DOE National Lab in Idaho, we have been exploring processing methods designed to develop a ‘map’ of the subsurface which is required before excavation can begin.”

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
