| No 'safest spot' to minimize risk of COVID-19 transmission on trains Posted: 22 Jun 2022 07:13 AM PDT Researchers have demonstrated how airborne diseases such as COVID-19 spread along the length of a train carriage and found that there is no 'safest spot' for passengers to minimise the risk of transmission. |
| 2021 heat wave created 'perfect storm' for shellfish die-off Posted: 21 Jun 2022 03:45 PM PDT It's hard to forget the excruciating heat that blanketed the Pacific Northwest in late June 2021. Temperatures in Oregon, Washington and British Columbia soared to well above 100 degrees Fahrenheit, with Seattle setting an all-time heat record of 108 degrees on June 28. A team has now compiled and analyzed hundreds of field observations to produce a comprehensive report of the impacts of the 2021 heat wave on shellfish. |
| What the nose doesn't know helps wildlife: Using olfactory cues to protect vulnerable species Posted: 21 Jun 2022 01:33 PM PDT Behavioral ecologists have discovered a way to harness animals' olfactory ability to protect vulnerable plants and endangered animals. |
| Modern wind turbines can more than compensate for decline in global wind resource Posted: 21 Jun 2022 12:51 PM PDT Wind energy contributes significantly to the energy sector's sustainable, low-CO2 transformation. However, the efficiency of wind turbines depends on available wind resources and the technical characteristics of the turbines. |
| Research highlights importance of large wood in streams for land-based animals Posted: 21 Jun 2022 07:56 AM PDT Land managers have invested millions of dollars annually since the 1980s to place large pieces of wood back in streams, owing primarily to its importance for fish habitat. But little is known about how large wood in streams impacts birds and land-based animals. Scientists are beginning to change that with a just-published paper that outlines what they observed from one year of footage from motion-triggered video cameras they set up near multiple large log jams in a creek just west of Corvallis, Oregon. |
| Remote sensing helps track carbon storage in mangroves Posted: 21 Jun 2022 07:56 AM PDT Researchers have developed a model that can estimate the productivity of mangrove forests at large scales. A remote sensing-based productivity model that considered the effects of tidal inundation was developed. Comparisons with carbon measurements from carbon flux towers showed that the model was able to accurately estimate the productivity of mangrove forests in China. The results highlight the potential of this type of model for assessing the capacity of mangrove forests to store carbon. |
| Wildlife--human conflicts could shift with climate change Posted: 21 Jun 2022 07:56 AM PDT Researchers modeled the risk of human -- elephant conflict in Thailand under different climate change scenarios using a risk framework. A spatial shift in the risk of conflict was observed with climate change, with northern areas and higher latitudes showing increasing risk in the future. These results can be used to develop planning strategies in affected communities and increase coexistence awareness. |
| Systematic warming pool discovered in the Pacific due to human activities Posted: 21 Jun 2022 06:14 AM PDT A long-term, increasingly warming pool of water in the northeast Pacific was recently discovered. It measures three million square kilometers, resulted from increased anthropogenic greenhouse-gas emissions, and is conducive to extreme heatwaves in the northeast Pacific. |
| Agriculture emissions pose risks to health and climate Posted: 21 Jun 2022 06:14 AM PDT Environmental engineers determine the economic cost of reactive nitrogen emissions from agriculture, and their significant risks to populations through air pollution and climate change. |
| Melting Arctic ice could transform international shipping routes, study finds Posted: 20 Jun 2022 12:21 PM PDT Melting ice in the Arctic Ocean could yield new trade routes in international waters, reducing the shipping industry's carbon footprint and weakening Russia's control over trade routes through the Arctic, a study found. |
| Science coverage of climate change can change minds Posted: 20 Jun 2022 12:21 PM PDT Science reporting on climate change does lead Americans to adopt more accurate beliefs and support government action on the issue -- but these gains are fragile, a new study suggests. |
| Fifth of global food-related emissions due to transport Posted: 20 Jun 2022 09:23 AM PDT Food transport constitutes 19 percent of food emissions, equivalent to 6 percent of emissions from all sources. High-income countries are responsible for nearly half of these emissions, leading researchers to conclude that among the rich, eating locally should be prioritised. |
| A small lowering of the groundwater level can destroy house foundations Posted: 20 Jun 2022 07:08 AM PDT A new thesis shows that wooden pile foundations show visible damage after only a year if the groundwater level lowers. This can cause settlements of buildings in a matter of a few years. |
| Posted: 20 Jun 2022 07:08 AM PDT Species have intrinsic value, but also provide ecosystem services of major economic value, for example, bees that pollinate our crops. However, as such values are hard to translate into figures, currently, they remain easy to dismiss altogether. In a new study, a research team conceptualizes a species stock market for unified valuation of all species. By using digitized information from museums, occurrence data, and DNA sequence databases, this market quantifies our knowledge of each species from scientific, societal, and economic points of view. |
| Evolutionary biology: The greening ashore Posted: 20 Jun 2022 07:08 AM PDT A team has been studying the current state of research on the plant colonization of land that occurred some 500 million years ago. |
| Posted: 17 Jun 2022 07:18 AM PDT A research team carried out field observations and conducted numerical simulations in the South China Sea (SCS) recently and revealed the never-before-seen characteristics of the three-dimensional ocean motion in the SCS through geophysical fluid dynamic theory. |
