| Could used beer yeast be the solution to heavy metal contamination in water? Posted: 13 Jun 2022 01:27 PM PDT A new study finds inactive yeast could be effective as an inexpensive, abundant, and simple material for removing lead contamination from drinking water supplies. The approach should be efficient and economic, even down to part-per-billion levels of contamination. |
| Posted: 13 Jun 2022 11:07 AM PDT The production of chemical substances normally requires environmentally harmful solvents. After researchers had produced organic substances without harmful substances by heating them in hot water, they can now chalk up another success: Through hydrothermal synthesis, they succeeded in jointly forming and combining organic and inorganic substances in the same reaction vessel. Specifically: an inorganic solid that encloses organic dye molecules. When exposed to light, which is by and large the most environmentally friendly energy resource, the hybrid material functions like a catalyst, i.e., a photocatalyst. Since the photocatalyst is a solid, it can be used multiple times. |
| How much spring nitrogen to apply? Pre-planting weather may provide a clue Posted: 13 Jun 2022 11:07 AM PDT With the rising cost of nitrogen fertilizer and its impacts on air and water quality, researchers want to help farmers make more informed fertilizer rate decisions. Their latest modeling effort aims to do that by examining the role of pre-growing season weather on soil nitrogen dynamics and end-of-season corn yield. |
| Closed-loop additive manufacturing fueled by upcycled plastic Posted: 13 Jun 2022 11:07 AM PDT Researchers have developed an upcycling approach that adds value to discarded plastics for reuse in additive manufacturing, or 3D printing. The readily adoptable, scalable method introduces a closed-loop strategy that could globally reduce plastic waste and cut carbon emissions tied to plastic production. |
| Forever chemicals linked to hypertension in middle-aged women Posted: 13 Jun 2022 08:21 AM PDT In a large, prospective study, the levels of per- and polyfluoroalkyl substances (PFAS), which are common human-made chemicals found in water, soil, air and food, were associated with an increased risk of high blood pressure among middle-aged women. The study found women in the highest one-third concentrations of all seven PFAS examined had a 71% increased risk of developing high blood pressure. |
| Research reveals the science behind this plant's blue berries Posted: 11 Jun 2022 07:07 AM PDT A new study confirms Lantana strigocamara as the second-ever documented case of a plant creating blue-colored fruits with layered fat molecules. |
| New CDC study details county-level distribution of seven diseases spread by blacklegged ticks Posted: 08 Jun 2022 03:44 PM PDT As surveillance for ticks and the disease-causing germs they spread improves, so does Americans' access to knowledge about where the risk of tickborne disease is greatest. Experts have assembled new surveillance data into a report that offers up-to-date county-level maps of both where blacklegged ticks are prevalent and where they've been found infected with any of seven different disease-causing germs, or pathogens. |
