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.

Throwing an 'axion bomb' into a black hole challenges fundamental law of physics

New research shows how the fundamental law of conservation of charge could break down near a black hole.

'Fool's gold' not so foolish after all

Posted: 25 Jun 2021 07:05 AM PDT

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.

Cosmic dawn occurred 250 to 350 million years after Big Bang

A new study suggests that the NASA James Webb Space Telescope (JWST), scheduled to launch in November, will be sensitive enough to observe the birth of galaxies directly.

New CRISPR 3.0 system for highly efficient gene activation in plants

Posted: 24 Jun 2021 10:55 AM PDT

Biologists have introduced a new and improved CRISPR 3.0 system in plants, focusing on gene activation. This third generation system focuses on multiplexed gene activation that can boost the function of multiple genes simultaneously. This system boasts four to six times the activation capacity of current state-of-the-art CRISPR technology, demonstrating high accuracy and efficiency in up to seven genes at once.

Quantum simulation: Measurement of entanglement made easier

Posted: 24 Jun 2021 08:44 AM PDT

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.

Solving a puzzle to design larger proteins

Posted: 24 Jun 2021 08:44 AM PDT

A team has identified the design principles for creating large 'ideal' proteins from scratch, paving the way for the design of proteins with new biochemical functions.

Cardiac atrophy findings may set course for preventing harm from long space flights

Posted: 24 Jun 2021 08:43 AM PDT

New findings shed light on the molecular triggers of rapid cardiac atrophy. Findings have potential implications for space travel.

Microspheres quiver when shocked

Posted: 23 Jun 2021 04:40 PM PDT

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.

Phone swabs that can accurately detect COVID-19

Posted: 23 Jun 2021 08:38 AM PDT

Researchers have developed an accurate, non-invasive, and low-cost method of testing for COVID-19 using samples taken from the screens of mobile phones.

Making our computers more secure

Posted: 23 Jun 2021 06:12 AM PDT

Researchers recently presented articles on memory safety that make computer systems more secure. This new research, which has zero to little effect on system performance, is already being used to create a processor.

Low-cost method for finding new coronavirus variants
