River-groundwater hot spot for arsenic Posted: 07 Apr 2020 01:49 PM PDT Naturally occurring groundwater arsenic contamination is a problem of global significance, particularly in South and Southeast Asian aquifers. |
How forest loss leads to spread of disease Posted: 07 Apr 2020 01:49 PM PDT In Uganda, loss of forested habitat increases the likelihood of interactions between disease-carrying wild primates and humans. The findings suggest the emergence and spread of viruses, such as the one that causes COVID-19, will become more common as the conversion of natural habitats into farmland continues worldwide. |
Making a connection: Two ways that fault segments may overcome their separation Posted: 07 Apr 2020 12:08 PM PDT In complex fault zones, multiple seemingly disconnected faults can potentially rupture at once, increasing the chance of a large damaging earthquake. Recent earthquakes including the 1992 Landers, 1999 Hector Mine and 2019 Ridgecrest earthquakes in California, among others, ruptured in this way. But how can seismologists predict whether individual fault segments might be connected and rupture together during a seismic event? |
Protecting the high seas: Identify biodiversity hotspots Posted: 07 Apr 2020 10:15 AM PDT Researchers use big data to identify biodiversity hotspots that could become the first generation of high seas marine protected areas. |
Adding a pinch of salt to El Niño models Posted: 07 Apr 2020 10:14 AM PDT When modeling the El Niño-Southern Oscillation (ENSO) ocean-climate cycle, adding satellite sea surface salinity -- or saltiness -- data significantly improves model accuracy, according to a new study. |
Climate change triggers Great Barrier Reef bleaching Posted: 07 Apr 2020 07:18 AM PDT The Great Barrier Reef is suffering through its worst bleaching event. This is the third bleaching within the space of five years. |
Litter problem at England's protected coasts Posted: 07 Apr 2020 04:27 AM PDT Beaches in or near England's Marine Protected Areas (MPAs) have the same levels of litter as those in unprotected areas, new research shows. |
Stream pollution from mountaintop mining doesn't stay put in the water Posted: 07 Apr 2020 04:27 AM PDT Since the 1980s, a mountaintop mine in West Virginia has been leaching selenium into nearby streams at levels deemed unsafe for aquatic life. Now, even though the mine is closed, a new study finds high concentrations of selenium in emerging stream insects and the spiders that eat them along the banks, an indication that the contaminant moves from water to land as it moves up the food chain. |
Scientists' warning to humanity on insect extinctions Posted: 06 Apr 2020 04:05 PM PDT As the human race continues to battle the COVID-19 pandemic, scientists have found that the planet's insects are also facing a crisis after accelerating rates of extinction have led to a worldwide fall in insect numbers. |
Posted: 06 Apr 2020 04:04 PM PDT Think your daily coffee, boutique gym membership and airport lounge access cost a lot? There may be an additional, hidden cost to those luxuries of urban living, says a new study: more flooding. For every percentage point increase in roads, parking lots and other impervious surfaces that prevent water from flowing into the ground, annual floods increase on average by 3.3%, the researchers found. |
Societal transformations and resilience in Arabia across 12,000 years of climate change Posted: 06 Apr 2020 04:04 PM PDT Recent archaeological and paleoenvironmental research in the Arabian Peninsula shows a range of societal responses to a series of extreme climatic and environmental fluctuations over thousands of years. These responses include migration, increasing population mobility, the introduction of pastoral lifeways, the management of water resources, and the construction of diverse structures to aid survival. Present-day constraints mean that many of these options are not available to populations living in the region today. |
Indigenous knowledge could reveal ways to weather climate change on islands Posted: 06 Apr 2020 04:04 PM PDT Some islands have such low elevation, that mere inches of sea-level rise will flood them, but higher, larger islands will also be affected by changes in climate and an understanding of ancient practices in times of climate change might help populations survive, according to researchers. |
Climate change to affect fish sizes and complex food webs Posted: 06 Apr 2020 08:25 AM PDT Global climate change will affect fish sizes in unpredictable ways and, consequently, impact complex food webs in our oceans, a new study has shown. The study analyzed three decades of data from 30,000 surveys of rocky and coral reefs around Australia. |
What is the Asian hornet invasion going to cost Europe? Posted: 06 Apr 2020 07:38 AM PDT Since its accidental introduction in 2003 in France, the yellow-legged Asian hornet Vespa velutina nigrithorax is rapidly spreading through Europe. Scientists have now tried to estimate the costs of the invasion regarding the potential damage to apiculture and pollination services. |
Making biofuels cheaper by putting plants to work Posted: 06 Apr 2020 06:28 AM PDT One strategy to make biofuels more competitive is to make plants do some of the work themselves. Scientists can engineer plants to produce valuable chemical compounds, or bioproducts, as they grow. Then the bioproducts can be extracted from the plant and the remaining plant material can be converted into fuel. But one important part of this strategy has remained unclear -- exactly how much of a particular bioproduct would plants need to make in order to make the process economically feasible? |
