Finding the missing piece in global oil life-cycle assessment Posted: 16 Nov 2021 02:50 PM PST New research offers a closer look at the relationship between decreasing demand for oil and a resilient, varied oil market -- and the carbon footprint associated with both. |
Seismic shockwave pattern may be redirecting earthquake damage Posted: 16 Nov 2021 11:48 AM PST According to physics, seismic waves from earthquakes should travel in a four-leaf clover pattern, but in the real world they behave more like ripples in a pond. New research has found the pattern hidden among low-frequency seismic waves, the kind that can topple buildings. The study looked at small earthquakes in northern Oklahoma and could change the way scientists think about potential damage from earthquakes. |
Synthetic biology yields easy-to-use underwater adhesives Posted: 16 Nov 2021 10:17 AM PST Researchers have used synthetic biology to bring together the best of spider silk and mussel foot protein in a biocompatible adhesive. |
Unique fossil: Seeds sprouting from an amber-encased pine cone Posted: 16 Nov 2021 10:17 AM PST New research has uncovered the first fossil evidence of a rare botanical condition known as precocious germination in which seeds sprout before leaving the fruit. |
Making solar energy even more sustainable with light-powered technology Posted: 16 Nov 2021 10:17 AM PST Scientists have identified a new process using coordination materials that can accelerate the use of low-cost, Earth-abundant materials with the potential to transform the energy sector by replacing silicone-based solar panels. |
Climate changed abruptly at tipping points in past Posted: 16 Nov 2021 08:14 AM PST Climate scientists identify abrupt transitions in climate records that may have been caused by the climate system crossing a tipping point. They devised a statistical method to determine whether these transitions are simply noise or evidence of a more significant change. Their method is less error-prone than previous methods, since it doesn't rely on human determination. It also allows comparing different records consistently and can identify important events that may have been overlooked in older studies. |
Air pollution decrease in India during COVID-19 lockdown not as high as originally thought Posted: 16 Nov 2021 08:13 AM PST Observational data shows air pollution in India decreased drastically in the first COVID-19 lockdown when emissions from vehicles naturally declined, but researchers say those numbers only tell part of the story -- blue skies and an absence of visible smog can be deceiving and hide pollutants that could potentially cause health issues. |
Electronic nose on a drone sniffs out wastewater treatment plant stink Posted: 16 Nov 2021 08:13 AM PST Researchers have engineered a portable electronic nose (e-nose) that's almost as sharp as a human nose at sniffing out the stink of wastewater treatment plants. Coupled with a drone, the lightweight e-nose can measure the concentration of different smells, predict odor intensity, and produce a real-time odor map of the plant for management. |
Alluring larvae: Competition to attract fish drives species diversity among freshwater mussels Posted: 16 Nov 2021 07:31 AM PST North America's freshwater mussels are both impressively diverse and highly imperiled. Nearly 300 species occur in the United States and Canada, and up to 40 species of the hard-shelled bottom dwellers can be found on a single stretch of a clean, swiftly flowing river. |
Posted: 16 Nov 2021 07:31 AM PST Researchers have modeled that pollutant emissions from the shipping sector increased significantly in major international seaports during the COVID-19 pandemic. |
A new approach to identify mammals good at learning sounds Posted: 16 Nov 2021 07:31 AM PST Why are some animals good at learning sounds? Did this skill appear when animals started 'faking' their body size by lowering calls? In a new study on a wide range of mammals,researchers revisit this question. Surprisingly, many animals who are skilled vocalists (such as dolphins and seals) actually sound higher than would be expected for their body size. |
Posted: 16 Nov 2021 07:31 AM PST Since 2015, researchers have been tracking emissions from oil and gas wells and report that, over that time, emissions from the region have fallen by half. But more analysis of leak rates shows that the oil and gas industry has a ways to go in stopping methane leaks, which impact the climate and human health and can impose costs on Utah's economy. |
Solar energy with an' ironclad future' Posted: 16 Nov 2021 07:31 AM PST Solar energy plays an important role in the fight against climate change as a substitute for fossil fuels. Dye-sensitized solar cells promise to be a low-cost supplement to the photovoltaic systems we know today. Their key feature is the dye sensitizers attached to their surface. Researchers continue to improve the performance with sensitizers using iron -- a commonly available and environmentally friendly metal. |
High impact climate events: Better adaptation through earlier prediction Posted: 15 Nov 2021 12:10 PM PST The prediction of high impact climate phenomena can be substantially improved by a new mathematical approach that analyses the connectivity and patterns between geographical locations, scientists say in a new publication. This can potentially save thousands of lives and avoid billions in economic losses. Prediction times for events like El Niño, monsoons, droughts or extreme rainfall could be increased substantially, to a month or in some cases even a year in advance, depending on the type of the event. The new framework can thus become key for improving adaptation to the global warming crisis. |
Sierra Nevada range should celebrate two birthdays Posted: 15 Nov 2021 06:02 AM PST New research reveals that after its initial formation 100 million years ago, the Sierra Nevada 'died' during volcanic eruptions that blasted lava across much of the American West 40 million to 20 million years ago. Then, tens of millions of years later, the Sierra Nevada mountain range as we know it today was 'reborn.' |
