  • UT Dallas study: Recent spikes in homicide rates don't tell whole story
    on January 11, 2018 at 7:16 pm

    Recent spikes in homicide rates across the nation have been attributed to causes ranging from civil unrest to the opioid epidemic, but new research found a much simpler explanation: The increases follow predictable fluctuations in rates over the past 55 years. […]

  • Protecting corridors is critical to preserving genetic diversity in tigers, and mizimising...
    on January 11, 2018 at 3:14 pm

    Tigers have lost 95% of their historical range, and what remains is highly fragmented. According to a new study, high traffic roads and densely populated urban areas are a severe impediment to tiger movement between fragments. Unplanned development in the future will result in loss of connectivity and an increased possibility of extinction for several tiger populations. To ensure future persistence, tiger populations need to be managed as a network of protected areas connected by corridors. […]

  • Recreational marijuana legalization: Do more youth use or do youth use more?
    on January 8, 2018 at 9:12 pm

  • Tobacco shops associated with crime in urban communities of color
    on January 6, 2018 at 3:34 pm

    Tobacco shops, also known as smoke shops, may represent potential 'nuisance properties' in urban communities of color, a study has found. Nuisance properties are properties where unsafe activities affecting public health and safety occur repeatedly. The study focused on 2014 violent and property crime data from South Los Angeles, a large urban community whose homicide rate is nearly four times the national rate. […]

  • Batman's Gotham City provides test case for community resilience model
    on January 5, 2018 at 6:52 pm

    If a community is resilient, it can withstand and recover from an unanticipated disaster, like an earthquake, fire or flood. But since every disaster and every community is unique, a uniform measure for defining 'resilience' has been hard to come by for engineers and social scientists. A new study offers an innovative approach to defining resilience that could help communities better prepare for hazards. […]

  • Jaguar conservation depends on neighbors' attitudes
    on December 28, 2017 at 10:06 pm

    A survey of residents near two major national parks in Panama indicates that jaguars deserve increased protection. But because most residents still support road-building in the parks, the survey team recommends further education to emphasize the connection between healthy ecosystems and jaguar survival. […]

  • Healthier air due to the low emission zone
    on December 20, 2017 at 5:20 pm

    Even though the total mass of particulate matter was only slightly reduced by the modernization of the vehicles, the scientists were able to prove that the Low Emission Zone Leipzig significantly contributes to the health protection of the population. […]

  • Expanding solar energy without encroaching on potential farmland and conservation areas
    on December 19, 2017 at 2:13 pm

    As the world tries to combat climate change, sustainable forms of energy are on the rise. Solar energy is of particular interest, but arrays of photovoltaic panels take up a lot of space and can compete for prime food-producing land. Now researchers have found plenty of places to install solar devices without taking up arable land, while generating enough power to help regions meet their energy goals. […]

  • Simulation model finds Cure Violence program and targeted policing curb urban violence
    on December 14, 2017 at 9:33 pm

    When communities and police work together to deter urban violence, they can achieve better outcomes with fewer resources than when each works in isolation, a simulation model created by researchers. […]

  • Effects of climate change could accelerate by mid-century
    on December 14, 2017 at 7:45 pm

    Environmental models are showing that the effects of climate change could be much stronger by the middle of the 21st century, and a number of ecosystem and weather conditions could consistently decline even more in the future. […]

  • Suburban ponds are a septic buffet
    on December 12, 2017 at 5:54 pm

    Human waste accounts for a high percentage of nutrients consumed by some animals and plants in suburban ponds, new research indicates. Researchers found that residential, suburban land use is altering the dynamics of the food chain, as well as where nutrients originate and how they move through pond ecosystems. […]

  • Residents of major Pakistan city are exposed to harmful pesticides, research reveals
    on November 30, 2017 at 10:02 pm

    Scientists have evaluated the organophosphate pesticide concentration in dust from farms and also from pesticide manufacturing plants in the megacity of Lahore. The results show dust in and around Lahore contains pesticide pollution that is a high health risk to all groups tested. […]

  • Improving urban green spaces increase thermal comfort of citizens
    on November 28, 2017 at 2:23 pm

    The link between urban green spaces and the thermal comfort sensation of people has been the focus of new research. The results provide significant suggestions to improve thermal comfort of citizens. […]

  • Air quality atlas for Europe: Mapping the sources of fine particulate matter
    on November 16, 2017 at 2:25 pm

    The European Commission published today an Air Quality Atlas for Europe. This new publication produced by the Commission's Joint Research Centre (JRC) helps to pave the way for targeted air quality measures by mapping the origins of fine particulate matter in Europe's largest cities. […]

  • Extensive loss of trees in African savannas: Blame human-started fires not elephants
    on November 8, 2017 at 5:41 pm

    Elephants are often blamed for extensive loss of woody vegetation in Northern Botswana, but study results suggest that this may not be the case. […]

  • Cities can cut greenhouse gas emissions far beyond their urban borders
    on November 7, 2017 at 4:31 pm

    Greenhouse gas emissions caused by urban households' purchases of goods and services from beyond city limits are much bigger than previously thought. These upstream emissions may occur anywhere in the world and are roughly equal in size to the total emissions originating from a city's own territory, a new study shows. This is not bad news but in fact offers local policy-makers more leverage to tackle climate change, the authors argue in view of the UN climate summit COP23 that just started. […]

  • Afterschool program environments linked to academic confidence and skills

  • Marijuana farming hurts environment, new study finds
    on November 1, 2017 at 12:27 am

    Planting cannabis for commercial production in remote locations is creating forest fragmentation, stream modification, soil erosion and landslides. Without land-use policies to limit its environmental footprint, the impacts of cannabis farming could get worse, according to a new study. […]

  • Spooky conservation: Saving endangered species over our dead bodies
    on October 31, 2017 at 5:03 pm

  • How cities can best fight climate change
    on October 26, 2017 at 5:53 pm

  • Investing in conservation pays off, study finds
    on October 25, 2017 at 6:11 pm
