| Big data-derived tool facilitates closer monitoring of recovery from natural disasters Posted: 22 Jul 2021 02:12 PM PDT By analyzing peoples' visitation patterns to essential establishments like pharmacies, religious centers and grocery stores during Hurricane Harvey, researchers have developed a framework to assess the recovery of communities after natural disasters in near real time. They said the information gleaned from their analysis would help federal agencies allocate resources equitably among communities ailing from a disaster. |
| Unravelling the knotty problem of the Sun's activity Posted: 22 Jul 2021 01:30 PM PDT A new approach to analysing the development of magnetic tangles on the Sun has led to a breakthrough in a longstanding debate about how solar energy is injected into the solar atmosphere before being released into space, causing space weather events. The first direct evidence that field lines become knotted before they emerge at the visible surface of the Sun has implications for our ability to predict the behavior of active regions and the nature of the solar interior. |
| Cattle losing adaptations to environment Posted: 22 Jul 2021 01:29 PM PDT Researchers have uncovered evidence showing that cattle are losing important environmental adaptations, losses the researchers attribute to a lack of genetic information available to farmers. After examining genetic material stretching back to the 1960s, they identified specific DNA variations associated with adaptations that could one day be used to create DNA tests for cattle -- tests that could tell farmers whether their cattle are suited for one environment or another. |
| Global warming may limit spread of dengue fever, new research finds Posted: 22 Jul 2021 11:19 AM PDT Infection with dengue virus makes mosquitoes more sensitive to warmer temperatures, according to new research. The team also found that infection with the bacterium Wolbachia, which has recently been used to control viral infections in mosquitoes, also increases the thermal sensitivity of the insects. The findings suggest that global warming could limit the spread of dengue fever but could also limit the effectiveness of Wolbachia as a biological control agent. |
| Smartphone screens effective sensors for soil or water contamination Posted: 22 Jul 2021 10:13 AM PDT The touchscreen technology used in billions of smartphones and tablets could also be used as a powerful sensor, without the need for any modifications. |
| Eco-friendly plastic from cellulose and water Posted: 22 Jul 2021 10:13 AM PDT Plastics offer many benefits to society and are widely used in our daily life: they are lightweight, cheap and adaptable. However, the production, processing and disposal of plastics pose a major global threat to the environment and human health. However, researchers have now found a sustainable method - 'hydrosetting', which uses water at normal conditions - to process and reshape a new type of hydroplastic polymer. |
| California's carbon mitigation efforts may be thwarted by climate change itself Posted: 22 Jul 2021 10:13 AM PDT To meet an ambitious goal of carbon neutrality by 2045, California's policymakers are relying in part on forests and shrublands to remove CO2 from the atmosphere, but researchers warn that future climate change may limit the ecosystem's ability to perform this service. |
| Visualizing a city's energy use Posted: 22 Jul 2021 08:31 AM PDT Researchers used the City of Pittsburgh to create a model built upon the design, materials and purpose of commercial buildings to estimate their energy usage and emissions. |
| Fully renewable energy feasible for Samoa, study suggests Posted: 22 Jul 2021 08:30 AM PDT The future of Samoa's electricity system could go green, a new study has shown. |
| Mobility restrictions can have unexpected impacts on air quality Posted: 22 Jul 2021 08:29 AM PDT Reduced mobility induced by the COVID-19 restrictions had only minor influence on particulate pollution levels, according to atmosphere studies in the Po Valley region of northern Italy. Eventually computer simulations indicated that the change in air quality led to an increase in secondary aerosol formation. |
| Targeted removals and enhanced monitoring can help manage lionfish in the Mediterranean Posted: 22 Jul 2021 08:29 AM PDT New research represents one of the first studies to examine the effectiveness of targeted lionfish removals from both an ecological and a socio-economic perspective. |
| 'Golden nail': Quarry near Salzgitter becomes global geological reference point Posted: 22 Jul 2021 08:28 AM PDT Scientists have found in Salzgitter-Salder what researchers have been searching for for more than 20 years: A geological formation that perfectly represents the transition from the Cretaceous Turonian to the Coniacian Age. The former limestone quarry is now considered a global reference point (GSSP) for the turn of the ages 89.4 million years ago. |
| New study reports strong indications of freshened groundwater offshore the Maltese Islands Posted: 22 Jul 2021 08:28 AM PDT Scientists report strong indications of freshened groundwater offshore the coastline between Valletta and Marsascala, in the south-east of Malta. |
| African dust transport across North Atlantic Posted: 21 Jul 2021 02:27 PM PDT Researchers chronicle the history of African dust transport, including three independent 'first' discoveries of African dust in the Caribbean Basin in the 1950s and 1960s. |
| Data identifies turbine wake clustering, improves wind farm productivity via yaw control Posted: 20 Jul 2021 08:44 AM PDT Researchers describe a real-time method for potentially helping turbine farms realize additional power from the clustering of their turbines. Their method requires no new sensors to identify which turbines at any given time could increase power production if yaw control is applied, and validation studies showed an increase of 1%-3% in overall power gain. |
| Using archeology to better understand climate change Posted: 19 Jul 2021 12:35 PM PDT Anthropologists, geographers and earth scientists look to the past to assess how different cultures have - and will - adapt to global warming. |
