| Global study finds the extent of pharmaceutical pollution in the world’s rivers Posted: 14 Feb 2022 12:48 PM PST A new study looking at the presence of pharmaceuticals in the world's rivers found concentrations at potentially toxic levels in more than a quarter of the locations studied. |
| Solar-powered system offers a route to inexpensive desalination Posted: 14 Feb 2022 11:40 AM PST Researchers developed a desalination system that is more efficient and less expensive than previous methods. In addition to providing fresh water, the process could be used to treat contaminated wastewater or generate steam for sterilizing medical instruments, all without requiring a power source other than sunlight. |
| Posted: 14 Feb 2022 11:40 AM PST With the early assessment of sustainable, newly developed chemicals and products it is possible to assess a potential risk of toxic substances being released at a later point in product cascades. In the course of the study the toxicity of sustainable biosurfactants, potentially applied in, e.g., bio-shampoos, and of a new technology for the economical deployment of plant protection agents were analyzed using a combination of computer modelling and laboratory experiments. The study is the first step towards a safe bioeconomy from an eco-toxicological stance, and which uses sustainable resources and processes to reduce environmental burdens significantly. |
| Secondary cratering on Earth: The Wyoming impact crater field Posted: 14 Feb 2022 11:40 AM PST Several dozen small impact craters, 10--70-m in size, have been discovered in southeastern Wyoming. A team of U.S. and German geoscientists found these ancient craters in exposed sedimentary layers from the Permian period (280 million years ago). After discovering the first craters, the team initially suspected that they are a crater-strewn field, formed by the breakup of an asteroid that entered the atmosphere. However, with the discovery of more and more craters over a wide area, this interpretation was ruled out. |
| Decolonize research to save heritage threatened by climate change Posted: 14 Feb 2022 08:18 AM PST Climate change threatens to destroy invaluable heritage sites and traditions in marginalized countries -- but empowering local people is key to adaptation. Locally led research and more equitable research funding are needed to address the true potential loss and damage to heritage from climate change, researchers argue. |
| Satellite imagery gives researchers timeline of when swine waste lagoons were built Posted: 14 Feb 2022 08:18 AM PST Researchers have developed an automated technique that uses satellite imagery to determine when swine waste lagoons were constructed, allowing researchers to determine the extent to which these facilities may have affected environmental quality. |
| Nuclear power may be the key to least-cost, zero-emission electricity systems Posted: 14 Feb 2022 08:17 AM PST Nuclear power generation can play a crucial role in helping the world reach a key goal of zero carbon emissions by the middle of the century, especially in countries with low wind resources, according to new work. |
| Study recommends six steps to improve our water quality Posted: 14 Feb 2022 06:58 AM PST Nitrogen fertilizers are critical for growing crops to feed the world, yet when applied in excess can pollute our water for decades. A new study provides six steps to address nitrogen pollution and improve water quality. |
| Posted: 14 Feb 2022 06:55 AM PST Within the next 30 years, a highly destructive Nankai Trough megathrust earthquake is predicted to hit southwest Japan. Understanding long-term slow slip events that occur along the plate interface between the subducting Philippine Sea plate and overriding Amurian plate under the Bungo Channel is essential for pinpointing when such an earthquake will happen. |
