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.

'Fool's gold' not so foolish after all

New research has found tiny amounts of gold can be trapped inside pyrite, commonly known as 'fool's gold,' which would make it much more valuable than its name suggests.

Scientists can predict and design single atom catalysts for important chemical reactions

Posted: 24 Jun 2021 11:15 AM PDT

Guided by quantum chemical calculations, scientists design and test a new single atom catalyst that converts propane to propylene with 100% efficiency, with little deactivation by coking. If adopted by industry, the catalyst could save billions of dollars and stop millions of tons of carbon dioxide being emitted into the atmosphere.

Ethane proxies for methane in oil and gas emissions

Measuring ethane in the atmosphere shows that the amounts of methane going into the atmosphere from oil and gas wells and contributing to greenhouse warming is higher than suggested by the U.S. Environmental Protection Agency, according to an international team of scientists who spent three years flying over three areas of the U.S. during all four seasons.

Are zebra mussels eating or helping toxic algae?

Posted: 24 Jun 2021 10:55 AM PDT

While invasive zebra mussels consume small plant-like organisms called phytoplankton, researchers discovered during a long-term study that zebra mussels can actually increase Microcystis, a type of phytoplankton known as 'blue-green algae' or cyanobacteria, that forms harmful floating blooms.

Asymmetry in CO2 emissions and removals could skew climate targets

Posted: 23 Jun 2021 06:12 AM PDT

Changes in climate resulting from carbon dioxide emissions into the Earth's atmosphere are not equal to the climate changes from deliberate carbon dioxide removals -- and assuming such a balance could lead to different climate outcomes that may skew climate targets, according to new research.
