Mapping the pulse of the city: innovative framework for dynamic population insight

Accurate, high-temporal-resolution population data are critical for urban planning and emergency response as cities grow. Traditional population census data, with their slow update cycles, cannot meet these demands. Researchers from the State University of New York at Buffalo have developed a new framework that combines remote sensing and mobile phone data, producing monthly population maps down to the census block level, providing more detailed population insights.

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.

Is Colombia’s deadly Nevado del Ruiz on the verge of a major eruption?

Hundreds of villagers who live in the shadow of the Western Hemisphere’s deadliest volcano, Colombia’s Nevado del Ruiz, have been on edge for nearly a month ever since the 17,000-foot-tall mountain started spewing plumes of ash and steam high into the atmosphere, indicating that an eruption could be imminent.

Spatial distribution of anti-Asian hate tweets during COVID-19

Anti-Asian hate language surged between January and March of 2020 with clusters of hateful tweets spread across the contiguous U.S. that varied in size, strength distribution and location. This is the first step towards helping officials predict where online racism may spill over to the streets as a public health threat.

Study looks at Impact of Native American Land Use on Forests

In a new article published in the Journal of Biogeography, SUNY Geneseo geographer Associate Professor Stephen Tulowiecki and four undergraduate researchers examined the influence of Native American land use on the composition of historic forests in the Northeastern United States. The team found that Native American settlements and land use had a lesser effect on the distribution of tree species across the region when compared to climate and soil conditions.

Study led by NUS researchers reveals climate change increases fluvial sediment in the high mountains of Asia

To examine the impact of a warmer and wetter climate in High Mountain Asia, Professor Lu Xixi and Dr Dongfeng Li from the Department of Geography at the National University of Singapore (NUS) Faculty of Arts and Social Sciences led an international team of researchers to conduct a new analysis of observations of headwater rivers in the area. The study revealed that fluvial sediment loads have been increasing substantially, even much faster than river water discharge. This has important implications for water quality, hydropower development and maintenance, and for the riverine carbon cycle.

How society’s inequalities showed up in COVID outcomes

During the 2020 lockdowns, residents of affluent areas in Salt Lake County, Utah were able to stay at home more than residents of the least affluent zip codes, suggesting that the “essential worker” occupations of the least-affluent areas, which are also the highest minority populations, placed them at greater risk for contracting COVID-19. Subsequently, the least-affluent zip codes experienced nearly ten times the COVID incidence rate of affluent areas.

The Indus basin: Untapped potential for long-term energy storage

Hydropower has massive potential as a source of clean electricity, and the Indus basin can be a key player in fulfilling long-term energy storage demands across Africa, Asia, Europe, and the Middle East. IIASA researchers explored the role the Indus…

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…

Ancient ostrich eggshell reveals new evidence of extreme climate change thousands of years ago

Evidence from an ancient eggshell has revealed important new information about the extreme climate change faced by human early ancestors. The research shows parts of the interior of South Africa that today are dry and sparsely populated, were once wetland…

Changes in Earth’s orbit enabled the emergence of complex life

Scientists at the University of Southampton have discovered that changes in Earth’s orbit may have allowed complex life to emerge and thrive during the most hostile climate episode the planet has ever experienced. The researchers – working with colleagues in…
