Environmental impact of hydrofracking vs. conventional gas/oil drilling: Research shows the differences may be minimal

Posted: 25 Jun 2021 02:31 PM PDT

Researchers have developed a new machine learning technique to holistically assess water quality data in order to detect groundwater samples likely impacted by recent methane leakage during oil and gas production. Using that model, the team concluded that unconventional drilling methods like hydraulic fracturing do not necessarily incur more environmental problems than conventional oil and gas drilling.

Quantum simulation: Measurement of entanglement made easier

Researchers have developed a method to make previously hardly accessible properties in quantum systems measurable. The new method for determining the quantum state in quantum simulators reduces the number of necessary measurements and makes work with quantum simulators much more efficient.

Microspheres quiver when shocked

Researchers report that they have demonstrated the use of DC electric fields to drive back-and-forth rotation of micro-particles in electric boundary layers. These particle oscillators could be useful as clocks that coordinate the organization of active matter and even, perhaps, orchestrate the functions of micron-scale robots.

Making our computers more secure
