| Making methane from CO2: Carbon capture grows more affordable Posted: 03 Sep 2021 06:53 AM PDT Researchers can make methane from captured CO2 and renewably sourced hydrogen, offering a path toward cheaper synthetic natural gas. |
| Astronomers create 3D-printed stellar nurseries Posted: 02 Sep 2021 02:48 PM PDT Astronomers can't touch the stars they study, but an astrophysicist is using 3-dimensional models that fit in the palm of her hand to unravel the structural complexities of stellar nurseries, the vast clouds of gas and dust where star formation occurs. Astronomers created the models using data from simulations of star-forming clouds and a sophisticated 3D printing process in which the fine-scale densities and gradients of the turbulent clouds are embedded in a transparent resin. |
| New food freezing concept improves quality, increases safety and cuts energy use Posted: 02 Sep 2021 02:48 PM PDT Shifting to a new food freezing method could make for safer and better quality frozen foods while saving energy and reducing carbon emissions, according to a new study. A complete change over to this new method of food freezing worldwide could cut energy use by as much as 6.5 billion kilowatt-hours each year while reducing the carbon emissions that go along with generating that power by 4.6 billion kg, the equivalent of removing roughly one million cars from roads. |
| Testing 1-2: New laser-based microphone calibration measures up Posted: 02 Sep 2021 02:47 PM PDT Researchers have conducted the first demonstration of a faster and more accurate way to calibrate certain kinds of microphones. The technique, which uses lasers to measure the velocity at which a microphone's diaphragm vibrates, performs well enough to overtake one of the main calibration methods used. |
| Mountaintop mining causes 40% loss of aquatic biodiversity Posted: 02 Sep 2021 02:47 PM PDT Using environmental DNA scans of Appalachian streams, researchers found that the effects of mountaintop coal mining in West Virginia are even more widespread than previously reported: Streams from heavily mined watersheds harbor 40% fewer species than streams with cleaner water. |
| Surprise result for solid state physicists hints at unusual electron behavior Posted: 02 Sep 2021 02:47 PM PDT While studying the behavior of electrons in iron-based superconducting materials, researchers observed a strange signal relating to the way electrons are arranged. The signal implies a new arrangement of electrons the researchers call a nematicity wave, and they hope to collaborate with theoretical physicists to better understand it. The nematicity wave could help researchers understand the way electrons interact with each other in superconductors. |
| Stellar collision triggers supernova explosion Posted: 02 Sep 2021 02:46 PM PDT The Very Large Array Sky Survey gave astronomers the first clue that ultimately revealed a dramatic story -- the remnant of a star that exploded long ago had plunged into the core of its companion star causing it, too, to explode as a supernova. |
| Putting a new theory of many-particle quantum systems to the test Posted: 02 Sep 2021 02:46 PM PDT New experiments using trapped one-dimensional gases -- atoms cooled to the coldest temperatures in the universe and confined so that they can only move in a line -- fit with the predictions of the recently developed theory of 'generalized hydrodynamics.' |
| Nano ‘camera’ made using molecular glue allows real-time monitoring of chemical reactions Posted: 02 Sep 2021 09:51 AM PDT Researchers have made a tiny camera, held together with 'molecular glue' that allows them to observe chemical reactions in real time. |
| How much energy do we need to achieve a decent life for all? Posted: 02 Sep 2021 09:50 AM PDT For many, an increase in living standards would require an increase in energy provision. At the same time, meeting current climate goals under the Paris Agreement would benefit from lower energy use. Researchers have assessed how much energy is needed to provide the global poor with a decent life and have found that this can be reconciled with efforts to meet climate targets. |
| Cold planets exist throughout our Galaxy, even in the galactic bulge Posted: 30 Aug 2021 11:02 AM PDT Researchers combined observations and modeling to infer the distribution of cold planets in the Milky Way. The results suggest that this distribution is not strongly dependent on the distance from the Galactic center. Cold planets seem to be present throughout our Galaxy, even in the galactic bulge, where their existence was uncertain. The findings could improve our understanding of both planetary formation and its history in the Milky Way. |
