| Swans sacrifice rest to squabble Posted: 08 Jul 2022 11:15 AM PDT Swans give up resting time to fight over the best feeding spots, new research shows. |
| Electric vehicles pass the remote road test Posted: 08 Jul 2022 09:36 AM PDT A new study, which demonstrates that even the most rural areas of Australia are feasible for electric vehicles, provides new hope for how the technology could be spread around the most secluded locations in other parts of the world. The study found the vast majority of residents, or 93 per cent, could travel to essential services with even the lower-range of electric vehicles currently available on the Australian market, without needing to recharge en route. |
| Narwhals show physiological disruption in response to seismic survey ship noise Posted: 08 Jul 2022 06:56 AM PDT The reaction of narwhals to the loud noise from seismic air guns used in oil exploration involves a disruption of the normal physiological response to intense exercise as the animals try to escape the noise. The overall effect is a large increase in the energetic cost of diving while a paradoxically reduced heart rate alters the circulation of blood and oxygen. |
| New research finds deep-sea mining noise pollution will stretch hundreds of miles Posted: 07 Jul 2022 11:21 AM PDT New research examines the potential for underwater noise pollution from seabed mining operations, which could affect the understudied species that live in the deep sea -- the largest habitat on Earth. |
| Historical dataset could help scientists better understand sharks Posted: 06 Jul 2022 10:33 AM PDT For the first time, the longest-running historical record of human-shark interactions in Australia is now accessible online. This follows a growing trend to make scientific datasets accessible, maximizing the use and impact of the data. |
| Posted: 06 Jul 2022 10:32 AM PDT The growing incidence of a potentially cancer-causing liver disease in children is associated with prenatal exposure to several endocrine-disrupting chemicals, researchers report. |
| Caught in the act: Key chemical intermediates in pollutant-to-fuel reaction identified Posted: 06 Jul 2022 06:29 AM PDT Researchers identified chemical intermediates in the hydrogenation of copper-adsorbed formate. Depending on the temperature, some of the hydrogenation product decomposed into formaldehyde. The activation energy was also quantified, based on experimental and computational work. These results will be useful for optimizing production of methanol fuel from carbon dioxide. |
| Seeing photovoltaic devices in a new light Posted: 05 Jul 2022 01:22 PM PDT Researchers described a novel effect in which the voltage generated by photovoltaic devices can change based on the color of incidence light. They show how this feature is due to random energy states that exist inside the antimony sulfiodide devices. This work may lead to more robust renewable energy generated by solar cells. |
| Ploughing and tilling soil on slopes is jeopardizing future farm yields Posted: 05 Jul 2022 06:38 AM PDT Ploughing and tilling on hilly slopes is causing farm soils to thin and threatens future crop yields, a new study finds. Scientists behind the study argue that unless farmers stop tilling hill slopes, over the long-term the soils on hillsides could thin to the point where growth of food crops is severely threatened. |
