| Scientists identify areas of high marine mammal diversity Posted: 04 Mar 2022 03:29 PM PST Sightings of more than 1 million marine mammals in the federally protected Northeast Canyons and Seamounts Marine National Monument and sites along the Atlantic Coast have been used to identify areas of high marine mammal diversity. These findings underscore the importance of ocean conservation as these waters face increasing impacts from human activities. |
| Artificial intelligence predicts algae potential as alternative energy source Posted: 04 Mar 2022 09:40 AM PST Texas A&M AgriLife Research scientists are using artificial intelligence to set a new world record for producing algae as a reliable, economic source for biofuel that can be used as an alternative fuel source for jet aircraft and other transportation needs. |
| During droughts, thirstier mountain forests could mean less water downstream Posted: 04 Mar 2022 08:20 AM PST Researchers found upstream forests' increased water consumption during droughts could leave less water downstream for forests, cities and wildlife during drought. |
| Posted: 04 Mar 2022 08:20 AM PST Major automotive manufacturers are ramping up production of electric trucks as a key strategy to reduce the greenhouse gas emissions of their vehicles. |
| Nealtican lava flow field, Popocatépetl volcano: A window to the past and future hazards Posted: 04 Mar 2022 07:10 AM PST The Popocatépetl volcano, located southeast of Mexico City, stands as the second highest peak in Mexico and is considered to be one of the potentially most dangerous volcanoes in the world, given its record of highly explosive eruptions over the last 23,000 years. |
| Predicting solar cell performance from terahertz and microwave spectroscopy Posted: 04 Mar 2022 07:09 AM PST Many semiconducting materials are possible candidates for solar cells. In recent years, perovskite semiconductors in particular have attracted attention, as they are both inexpensive and easy to process and enable high efficiencies. Now a new study shows how terahertz (TRTS) and microwave spectroscopy (TRMC) can be used to reliably determine the mobility and lifetime of the charge carriers in new semiconducting materials. Using these measurement data it is possible to predict the potential efficiency of the solar cell in advance and to classify the losses in the finished cell. |
| Cutting losses: Engineering research equips solar industry for improved performance Posted: 04 Mar 2022 06:03 AM PST Researchers have succeeded in identifying a technique that makes cadmium, selenium and telluride (CdSeTe) solar cells more efficient than silicon cells. |
| Scooting to a new era in active transportation Posted: 03 Mar 2022 04:14 PM PST In recent years, shared electric scooters (e-scooters) have taken cities by storm. But how are people using this new mode of transportation? A new study has some interesting data to share on e-scooter users. Self-reported safety behaviors didn't always match with observations: the reported use of helmets (13% while riding) far outweighed researchers' observations in Salt Lake City (2% of riders) or Tucson (2% of riders). |
| How triple-pane windows stop energy (and money) from flying out the window Posted: 03 Mar 2022 01:20 PM PST Next generation triple-pane windows provide builders with lower cost options and help homeowners conserve energy, reduce noise, and lower home energy bills. |
| Changes in air pollution linked with dry spells in Asia and summer heatwaves in Europe Posted: 03 Mar 2022 06:57 AM PST Analysis of climate models finds aerosols from air pollution were far more important in influencing the Eurasian summer jet stream, which shapes Northern Hemisphere weather, than previously thought. It counters the previous suggestion that greenhouse gas-forced Arctic warming was the main driver of the weakening of the jet stream. This is the first time that aerosols have been shown so clearly to affect such an important feature of the large-scale atmospheric circulation, which influences strength of storms and wet and dry weather in different regions. |
| What explains our lower back pain? Anthropologists turn to Neanderthals for answers Posted: 03 Mar 2022 06:57 AM PST Examining the spines of Neanderthals, an extinct human relative, may explain back-related ailments experienced by humans today, a team of anthropologists has concluded in a new comparative study. |
| Graphene sensor rapidly detects opioid metabolites in wastewater Posted: 25 Feb 2022 02:36 PM PST An atom-thick sheet of graphene is the basis of a new, penny-sized sensor that can quickly and efficiently detect and measure opioid byproducts in wastewater, researchers report. |
