| Journey of PFAS in wastewater facilities highlights regulation challenges Posted: 26 May 2021 08:55 AM PDT Researchers have conducted two of the first studies in New England to collectively show that toxic human-made chemicals called PFAS (per-and polyfluoroalkyl substances), found in everything from rugs to product packaging, end up in the environment differently after being processed through wastewater treatment facilities -- making it more challenging to set acceptable screening levels. |
| Aquaculture turns biodiversity into uniformity along the coast of China Posted: 26 May 2021 08:55 AM PDT Fishery and aquaculture have given rise to an enormous uniformity in the diversity of bivalves along the more than 18,000 kilometer long Chinese coast, biologists report. |
| The world's smallest fruit picker controlled by artificial intelligence Posted: 26 May 2021 08:55 AM PDT Inspired by insects that suck nutrients directly from plant veins, physicists have studied whether valuable chemical substances can be harvested directly from the cells of plants. Using a harvester measuring only a few microns, they have now achieved a technological breakthrough. |
| Warm ice may fracture differently than cold ice Posted: 26 May 2021 08:55 AM PDT Researchers have found strong evidence that warm ice - that is, ice very close in temperature to zero degrees Celsius - may fracture differently than the kinds of ice typically studied in laboratories or nature. A new study takes a closer look at the phenomenon. |
| What causes the deep Earth's most mysterious earthquakes? Posted: 26 May 2021 08:55 AM PDT The cause of Earth's deepest earthquakes has been a mystery to science for more than a century, but a team of scientists may have now cracked the case.
