High blood pressure, formally known as hypertension, is a leading cause of heart disease in the United States, impacting nearly half of all adults. Approximately one in 10 of these patients experience drug-resistant hypertension that can be difficult to address, but according to researchers at Penn State, tiny devices that gently shock one of the body's most critical arteries could offer effective treatment.

New reactor design produces renewable methane from carbon dioxide

An internal view of the reactor system that efficiently converts carbon dioxide and renewable electricity into methane.

An international team, led by Penn State’s Institute of Energy and the Environment Director Bruce Logan, has developed a new reactor design that efficiently converts carbon dioxide and renewable electricity into methane — the primary component of natural gas — while scaling the system up by roughly an order of magnitude without sacrificing performance.
