| The role of genes in prenatal responses to air pollution Posted: 07 Apr 2022 11:19 AM PDT Exposure to pollution during pregnancy can have many adverse effects in infants and children that can even extend into adulthood. For example, air pollution exposure is associated with increased risk of low birth weight, preterm birth and risk for developing asthma later in life. Much of this is due to the fast pace of fetal growth and development; however, the exact ways pollutants have these effects and the roles of genes related to immune function and stress response are not fully understood. |
| New evidence suggests California's environmental policies preferentially protect whites Posted: 07 Apr 2022 11:19 AM PDT Asian and Hispanic communities experience significantly more air pollution from economic activity compared to predominantly white neighborhoods across the state of California, according to new research. |
| Turbulence from spawning fish keeps a healthy circulation in coastal waters Posted: 07 Apr 2022 11:18 AM PDT A new study has shown how fish influence ocean ecosystems in coastal regions, revealing for the first time how they circulate nutrients and oxygen around the waters when they spawn. This process is key to keeping the ecosystems running. |
| Private protected areas help conserve overlooked and threatened regions Posted: 07 Apr 2022 11:18 AM PDT New research shows that private protected areas help conserve underrepresented biomes and highly threatened regions. Researchers have assessed 17,561 privately protected areas in 15 countries across five continents. Their findings reveal that compared to state protected areas, PPAs are twice as likely to be in areas with the greatest human disturbance, such as regions used for agriculture and mining. They are three times more likely to be in biomes with almost no established conservation reserves and protect 1.2% of key biodiversity areas. |
| Ocean water samples yield treasure trove of RNA virus data Posted: 07 Apr 2022 11:18 AM PDT Ocean water samples collected around the world have yielded a treasure trove of new data about RNA viruses, expanding ecological research possibilities and reshaping our understanding of how these small but significant submicroscopic particles evolved. |
| Sustainable strategies to treat urban runoff Posted: 07 Apr 2022 07:11 AM PDT Researchers call for cities to better manage and treat urban runoff to protect sources of drinking water and reduce the impacts on aquatic ecosystems. |
| Uranium detectable in two-thirds of US community water system monitoring records Posted: 07 Apr 2022 07:11 AM PDT A study on metal concentrations in U.S. community water systems (CWS) and patterns of inequalities, researchers found that metal concentrations were particularly elevated in CWSs serving semi-urban, Hispanic communities independent of location or region, highlighting environmental justice concerns. These communities had the highest levels of uranium, selenium, barium, chromium, and arsenic concentrations. Even at low concentrations, uranium in particular represents an important risk factor for the development of chronic diseases. |
| Selective breeding sustainably protects honey bees from Varroa mite Posted: 07 Apr 2022 07:10 AM PDT A new breed of honey bees provides a major advance in the global fight against the parasitic Varroa mite, new research shows. |
| How mountain streams signal climate change Posted: 07 Apr 2022 07:10 AM PDT A new tool can better assess an important but overlooked indicator of global warming: the variety of bugs, worms, and snails living in high mountain streams. |
| Surfer science supports seawater study Posted: 07 Apr 2022 07:10 AM PDT Seawater samples taken from a surfboard have helped scientists understand microscopic life in the waves, new research shows. |
| Amazon rainforest foliage gases affect the Earth’s atmosphere Posted: 06 Apr 2022 02:20 PM PDT Researchers have uncovered a plant-derived process that leads to the formation of aerosol particles over the Amazon rainforest and potentially other forested parts of the world. |
| Where storm surges are increasing the most Posted: 06 Apr 2022 02:20 PM PDT Extreme storms, like Sandy or Xaver, don't happen often but when they do, cities need to be prepared. That's why researchers have developed a new method to determine where extreme events, like 100-year storm floods, are more likely to occur, whether the likelihood of such extremes is changing over time and why. |
| To save California's whales, put overlooked threats into policy Posted: 06 Apr 2022 01:06 PM PDT Current whale-protection policies in California rarely address the overlapping, compounding stressors facing whale populations. |
| Reducing air pollution by changing the way we dry our laundry Posted: 06 Apr 2022 01:05 PM PDT A new study has revealed that tumble drying a load of laundry releases almost the same amount of potentially harmful microfibers into the air as those released down the drain during machine washing of the same load. |
| Good parenting evolved multiple times in moss animals Posted: 06 Apr 2022 10:24 AM PDT The spindly filaments and coral-like colonies of the ancient phylum of marine animals known as bryozoans likely aren't the first thing that come to mind when you envision safe and protective child care. But a new study on the 600-million-year history of these obscure animals highlights the important role good parenting has played in their enduring success. In one of the largest genetic analyses of invertebrate marine organisms to date, researchers sequenced DNA from hundreds of alcohol-preserved specimens stored in more than 20 museums around the world. |
| New study reveals extent of labor abuse and illegal fishing risks among fishing fleets Posted: 05 Apr 2022 08:52 AM PDT A new modeling approach combines machine learning and human insights to map the regions and ports most at risk for illicit practices, like forced labor or illegal catch, and identifies opportunities for mitigating such risks. |
| Recent changes in bird morphology -- probably due to global warming, study finds Posted: 05 Apr 2022 07:28 AM PDT Researchers have found changes in the morphology of many birds in Israel over the past 70 years, which they interpret to be a response to climate change. |
