Researchers at the National Energy Technology Laboratory (NETL) are taking significant steps that can help boost production of oil and natural gas that can be recovered from unconventional formations. The method focuses on recovering these additional resources in shale and other tight reservoirs that have already produced hydrocarbons through hydraulic fracturing in primary recovery operations but still contain large amounts of oil and gas trapped within rocks. In unconventional formations, only a small percentage of hydrocarbons in place are typically extracted. While the new research could help ensure affordable, reliable, and secure energy for the United States. Primary recovery from...

WASHINGTON, Feb 4 (Reuters) - President Donald Trump's overhaul of U.S. foreign assistance has led to chaos in the aid and development field, leaving hundreds of contractors in a severe financial crunch with some already having to lay off staff and others facing millions of dollars in unpaid invoices. Hours after coming into office on Jan. 20, Trump ordered a sweeping review of almost all U.S. foreign aid and tasked billionaire Elon Musk, who has falsely accused USAID of being a "criminal" organization, with scaling down the agency. Since then, dozens of USAID staff has been put on leave, hundreds...

There’s a strange wave phenomenon that’s plagued rocket scientists for years, a lurking threat with the power to destroy an engine at almost any time. For decades, scientists have had a limited understanding of how or why it happens because they could not replicate or investigate the problem under controlled laboratory conditions. Scientists generally believe that these powerful and unstable sound waves, created by energy supplied by the combustion process, were the cause of rocket failures in several U.S. and Russian rockets. Scientists have also observed these mysterious oscillations in other propulsion and power-generating systems such as missiles and gas...

Ancient Architectural Acoustic Resonance Patterns and Regional Brain Activity Authors: Cook, Ian A.; Pajot, Sarah K.; Leuchter, Andrew F.Source: Time and Mind, Volume 1, Number 1, March 2008 , pp. 95-104(10)Publisher: Berg Publishers Abstract: Previous archaeoacoustic investigations of prehistoric, megalithic structures have identified acoustic resonances at frequencies of 95-120 Hz, particularly near 110-12 Hz, all representing pitches in the human vocal range. These chambers may have served as centers for social or spiritual events, and the resonances of the chamber cavities might have been intended to support human ritual chanting. We evaluated the possibility that tones at these frequencies might...
