U.S. Drug Overdose Deaths More Than Quadrupled from 1999 to 2020

Regardless of race, age, geography or urbanization, drug overdose deaths in the U.S. more than quadrupled from 1999 to 2020, causing 1,013,852 deaths. The rates increased 4.4 times from 6.9 per 100,000 in 1999 to 30 per 100,000 in 2020.

Synthesizing 200 Years of Research on the Urban Impact on Regional Climate and Extreme Weather

Urbanization has noticeable effects on processes at and near the Earth’s surface, affecting weather and climate. An international team of scientists reviewed more than 500 sources from the scientific literature produced over nearly 200 years on effects of urbanization on extreme weather and regional climate to better synthesize this knowledge and direct future research.

Less Rain in Town, More Rain on the Farm: the Effects of Urbanization and Irrigation on Mid-Atlantic Summer Precipitation

Researchers investigated how large-scale urbanization and irrigation in the United States affect the three dominant types of summer precipitation in the mid-Atlantic region. They found that urbanization suppresses all three types of precipitation. Irrigation enhances non-convective and isolated deep convection precipitation, and its effects on mesoscale convective systems (MCS) depends on whether an MCS formed locally or remotely.

FAU Harbor Branch Lands U.S. EPA Grant for ‘Hands-on’ Indian River Lagoon Field Trip

The project will host 125 field trips, which will educate as many as 3,125 socially disadvantaged middle and high school students about Florida’s natural resources and the importance of conserving them.

Diverse landscapes at the heart of bee conservation

New research from the University of Georgia revealed that mixed land use – such as developments interspersed with forest patches – improves bee diversity and is leading to new solutions for bee conservation. The researchers hypothesized that development would negatively affect bee diversity, but the results of the study were surprising. They found that small amounts of development actually had a positive impact on the number of bee species present in a given area.

Higher socioeconomic status linked to increased air pollution exposure in China

For the first time, a University of Washington led team has uncovered that people living in China who have a higher socioeconomic status are actually more exposed to outdoor air pollution, also known as ambient air pollution. This finding runs contrary to existing studies conducted throughout North America, which have shown that higher pollution levels tend to be experienced among people with lower socioeconomic status.

Evolution in Chicago’s clover: DePaul University researchers help chart global human impact on nature

Jalene LaMontagne, associate professor of ecology, and Windsor Aguirre, associate professor of evolutionary biology, are among hundreds of researchers who collected clover in 160 cities all over the world. The research, published this week in the journal “Science,” offers insight into how urbanization is transforming the genetic properties of plants and animals around us.

Living near woodlands is good for children and young people’s mental health

Analysis of children and young people’s proximity to woodlands has shown links with better cognitive development and a lower risk of emotional and behavioural problems, in research led by UCL and Imperial College London scientists that could influence planning decisions…

World’s first 3D-printed steel footbridge unveiled by robot in Amsterdam

The bridge, which is over four years in the making and is led by Dutch company MX3D, will be a ‘living laboratory’ in Amsterdam’s city centre. Using its vast network of installed sensors, Imperial College London researchers will measure, monitor…

New characterisation strategy proves promising in high-purity metal separation

Metals with similar chemical properties are usually extracted together, which limits the opportunities to separate high-purity metals. To increase those opportunities, it’s important to understand how different metal species act during the solvent extraction process. Researchers from the Institute of…

Vertical greenery can act as a stress buffer, NTU Singapore study finds

Vertical greenery ‘planted’ on the exterior of buildings may help to buffer people against stress, a Nanyang Technological University, Singapore (NTU Singapore) study has found. The benefits of nature on mental health and for wellbeing have long been recognised, and…

Finding pathways for sustainable development in Africa

A new project funded under the Belmont Forum’s joint Collaborative Research Action on Pathways to Sustainability will develop novel tools and capacities to understand and manage interlinkages between the Sustainable Development Goals (SDGs), and support sustainable development pathways for African…

Study: A quarter of adults don’t want children — and they’re still happy

Parenting is one of life’s greatest joys, right? Not for everyone. New research from Michigan State University psychologists examines characteristics and satisfaction of adults who don’t want children. As more people acknowledge they simply don’t want to have kids, Jennifer…

Biodiversity ‘Hotspots’ Imperiled along California’s Streams

A study of woodland ecosystems that provide habitat for rare and endangered species along streams and rivers throughout California reveals that some of these ecologically important areas are inadvertently benefitting from water that humans are diverting for their own needs. Though it seems a short-term boon to these ecosystems, the artificial supply creates an unintended dependence on its bounty, threatens the long-term survival of natural communities and spotlights the need for changes in the way water is managed across the state.

Research uncovers broadband gaps in US to help close digital divide

High-speed internet access has gone from an amenity to a necessity for working and learning from home, and the COVID-19 pandemic has more clearly revealed the disadvantages for American households that lack a broadband connection. To tackle this problem, Michigan…

UN: More harmful algal bloom impacts emerge amid rising seafood demand, coastal development

UNESCO IOC delivers 1st global assessment report after 7 years’ work by 109 experts in 35 countries, creating a baseline to detect and gauge the changing distribution, frequency, and intensity of harmful — often poisonous — algal blooms

Cultural, belief system data can inform gray wolf recovery efforts in US

Humans regularly exert a powerful influence on the survival and persistence of species, yet social-science information is used only sporadically in conservation decisions. Researchers at Colorado State University and The Ohio State University have created an index depicting the mix…

UM research suggests social factors important for human-wildlife coexistence

MISSOULA – In bear country, it’s normal to find bruins munching down on temptations left out by humans – from a backyard apple tree to leftovers in the trash bin – but these encounters can cause trouble for humans and…
