| Study evaluates biodiversity impacts of alternative energy strategies Posted: 13 Jul 2021 03:44 PM PDT Climate change mitigation efforts have led to shifts from fossil-fuel dependence to large-scale renewable energy. However, renewable energy sources require significant land and could come at a cost to ecosystems. A new study evaluates potential conflicts between alternative energy strategies and biodiversity conservation. |
| Air pollution exposure linked to poor academics in childhood Posted: 13 Jul 2021 11:58 AM PDT Children exposed to elevated levels of air pollution may be more likely to have poor inhibitory control during late childhood and poor academic skills in early adolescence, including spelling, reading comprehension, and math skills. Difficulty with inhibition in late childhood was found to be a precursor to later air pollution-related academic problems. Interventions that target inhibitory control might improve outcomes. |
| Are silver nanoparticles a silver bullet against microbes? Posted: 13 Jul 2021 11:58 AM PDT Antimicrobials are used to kill or slow the growth of bacteria, viruses and other microorganisms. They are essential to preventing and treating infections, but they also pose a global threat to public health when microorganisms develop antimicrobial resistance. A lab studied the mechanisms behind bacterial resistance to silver nanoparticles to determine if their ubiquitous use is a solution to this challenge or if it is perhaps fueling the fire. |
| The two-thousand-year-old mystery of the havoc-wreaking worm Posted: 13 Jul 2021 11:57 AM PDT Humans have known for over two thousand years that shipworms, a worm-like mollusk, are responsible for damage to wooden boats, docks, dikes and piers. Yet new research reveals that we still don't know the most basic thing about them: how they eat. |
| Poor and minority communities suffer more from extreme heat in US cities Posted: 13 Jul 2021 08:08 AM PDT Low-income neighborhoods and communities with higher Black, Hispanic and Asian populations experience significantly more urban heat than wealthier and predominantly white neighborhoods within a vast majority of populous US counties, according new research. |
| Global study reveals effectiveness of protected forests Posted: 13 Jul 2021 08:08 AM PDT Scientists have published a global study on the effectiveness of protected areas in preventing deforestation. The study explored the success of country-level protected areas at reducing forest loss, and used machine learning to uncover some of the factors that contribute to differences in effectiveness. |
| Mathematical model predicts the movement of microplastics in the ocean Posted: 13 Jul 2021 08:08 AM PDT New research has identified the processes that underpin the trajectories of microplastics below the ocean surface. The authors analyzed how biofouling -- the accumulation of algae on the surface of microplastics -- impacts the vertical movement of buoyant particles. |
| The rat's whiskers: Multidisciplinary research reveals how we sense texture Posted: 13 Jul 2021 08:08 AM PDT Two very different teams of scientists have worked together to reveal important insights into how we sense texture by looking at the whiskers of a rat. |
| Resilience, not collapse: What the Easter Island myth gets wrong Posted: 13 Jul 2021 06:01 AM PDT New research suggests that the demographic collapse at the core of the Easter Island myth didn't really happen. |
| Dire impacts downstream of Nile River dam: Study Posted: 13 Jul 2021 06:01 AM PDT Downstream water supply and economic losses could substantially disrupt Egypt, according to a new analysis that offers potential solutions to avoid conflict over the dam. |
| When a single tree makes a difference Posted: 12 Jul 2021 03:33 PM PDT A single tree along a city street or in a backyard can provide measurable cooling benefits, according to a new study. |
| Childhood lead exposure may adversely affect adults' personalities Posted: 12 Jul 2021 12:19 PM PDT A study sampled more than 1.5 million people in 269 U.S. counties and 37 European nations. Researchers found that those who grew up in areas with higher levels of atmospheric lead had less adaptive personalities in adulthood -- lower levels of conscientiousness and agreeableness and higher levels of neuroticism. |
| Mapping how sea-level rise adaptation strategies impact economies and floodwaters Posted: 12 Jul 2021 12:03 PM PDT By 2100, sea levels are expected to rise by almost seven feet in the Bay Area. New research shows how traditional approaches to combating sea-level rise can create a domino effect of environmental and economic impacts for nearby communities. |
