Rapid, accessible and highly accurate detection of addictive substances such as opiates and cocaine is vital to reducing the adverse personal and societal impacts of addiction, something current drug detection systems can take too long to provide. However, on-site, real-time monitoring of abused drugs in a patient's system could alert [...]

A novel multidimensional characterization approach that combines several characterization techniques, allowing to get materials properties of the heterostructure with (almost) nanometer resolution. The method combines several microscopy tools into a multidimensional imaging tool that allows the inspection of materials' optical properties at a resolution much higher than with regular [...]

Sinuous stellar jets meander lazily across a field of stars in new images. The gently curving stellar jets are the outflow from young stars, and astronomers suspect their sidewinding appearances are caused by the gravitational attraction of companion stars. These crystal-clear observations were made using the Gemini South telescope's adaptive [...]

The energy systems that power our lives also produce wasted heat -- like heat that radiates off hot water pipes in buildings and exhaust pipes on vehicles. A new flexible thermoelectric generator can wrap around pipes and other hot surfaces and convert wasted heat into electricity more efficiently than previously [...]

Industry and private consumers alike depend on oil and gas pipelines that stretch thousands of kilometers underwater. It is not uncommon for these pipelines to become clogged with deposits. Until now, there have been few means of identifying the formation of plugs in-situ and non-destructively. Measurements now show that neutrons [...]

There are few environments as unforgiving as the ocean. Its unpredictable weather patterns and limitations in terms of communications have left large swaths of the ocean unexplored and shrouded in mystery. “The ocean is a fascinating environment with a number of current challenges like microplastics, algae blooms, coral bleaching, and rising [...]

While mammograms are currently the gold standard in breast cancer screening, swirls of controversy exist regarding when and how often they should be administered. On the one hand, advocates argue for the ability to save lives: Women aged 60-69 who receive mammograms, for example, have a 33 percent lower risk [...]
