Location plays critical role in assimilation of U.S. immigrants
Research from the University of Chicago finds immigrant populations within the United States assimilate in different ways, with demographics and geography playing critical roles, according to a study by Angela S. García, a sociologist and assistant professor at the University of Chicago School of Social Service Administration.

Study suggests exposure to trees, the sky and birdsong in cities beneficial for mental wellbeing
Researchers at King's College London, landscape architects J & L Gibbons and art foundation Nomad Projects have used smartphone-based technology to assess the relationship between nature in cities and momentary mental wellbeing in real time. They found that (i) being outdoors, seeing trees, hearing birdsong, seeing the sky, and feeling in contact with nature were associated with higher levels of mental wellbeing, and that (ii) the beneficial effects of nature were especially evident in those individuals with greater levels of impulsivity who are at greater risk of mental health issues.

Installing rooftop vegetable gardens for sustainable cities
Installing rooftop vegetable gardens for sustainable cities
From producing food to regulating water runoff, urban agriculture has a lot to offer. Scientists from INRA and AgroParisTech have shown that rooftop vegetable gardens are an interesting way to recycle urban waste, produce food, and retain rainwater. Their The challenges of making today's cities more sustainable are legion: waste management, food supplies, sensitivity to heatwaves and the risk of flooding linked notably to the impermeabilisation of soils.

The Inflatable Bridge
The Inflatable Bridge
A wildlife crossing over the upcoming Koralm railway is being built, using a new construction technique developed by TU Wien. Traditional support structures are replaced by an air cushion. The shell construction methods which are usually used to build bridges and domes generally rely on expensive support structures.

3D Printing in concrete
3D Printing in concrete
Research news Concrete components are traditionally made by casting. But the mold needed places significant limitations on design possibilities. 3D printing now provides new freedom in shaping. Researchers at the Technical University of Munich (TUM) are experimenting with various processes, including selective binding.

Himalayan river system influenced ancient Indus Civilisation
Himalayan river system influenced ancient Indus Civilisation
Scientists have found that much of the Indus thrived around an extinct river, challenging ideas about how urbanisation in ancient cultures evolved. The Indus or Harappan Civilisation was a Bronze Age society that developed mainly in the northwestern regions of South Asia from 5300 to 3300 years ago, at about the same time as urban civilisations developed in Mesopotamia and Egypt.

One in ten young adults experience homelessness during one year, Chapin Hall finds
A groundbreaking study released Nov. 15 by Chapin Hall at the University of Chicago reveals one in 10 young adults between the ages of 18 and 25, and at least one in 30 adolescents between the ages of 13 and 17, experience some form of homelessness over the course of a year. This study captures youth homelessness broadly, including situations such as sleeping on the streets, in shelters, running away and couch surfing.

Urban trees are growing faster worldwide
Urban trees are growing faster worldwide
Research news Trees in metropolitan areas have been growing faster than trees in rural areas worldwide since the 1960s. This has been confirmed for the first time by a study on the impact of the urban heat island effect on tree growth headed by the Technical University of Munich (TUM). The analysis conducted by the international research team also shows that the growth of urban trees has already been exposed to changing climatic conditions for a long period of time, which is only just beginning to happen for trees in rural areas.

Database clarifies bottom-up design of cement
An international team of researchers from EPFL, ETHZ and Rice University in Houston creates a database tool for the design of cement, a component of concrete, the most-used construction material in the world and a significant source of atmospheric carbon dioxide.

A concrete solution
A concrete solution
Cement materials, including cement paste, mortar, and concrete, are the most widely manufactured materials in the world. Their carbon footprint is similarly hefty: The processes involved in making cement contribute almost 6 percent of global carbon emissions. The demand for these materials is unlikely to decline any time soon.

Statins reduce deaths from heart disease by 28 per cent, says longest ever study
Statins reduce deaths from heart disease by 28 per cent, says longest ever study
The study focused on men with high levels of 'bad' cholesterol and no other risk factors or signs of heart disease Previous research has shown the benefit of statins for reducing high cholesterol and coronary heart disease risk amongst different patient populations. However, until now there has been no conclusive evidence from trials for current guidelines on statin usage for people with very high levels of low density lipoprotein (LDL) cholesterol (above 190mg/dL) and no established heart disease.

Industrial "edge cities" have helped China grow
China's massive investment in industrial parks has paid economic dividends while reshaping the urban areas where they are located, according to a newly published study co-authored by an MIT expert on urban economics. The study finds the creation of industrial parks does not just add to growth within the areas designated for manufacturing; it significantly increases economic production and consumption of many kinds for more than a mile in all directions from the boundaries of industrial parks.

When time ravages from within
When time ravages from within
Will the reinforced concrete bridge still be standing for years to come, or has corrosion already set in? ETH scientists have discovered that previous concrete samples were too small to allow a reliable statement on the condition of reinforced concrete. Taminabrücke opened in June this year following four years of construction.

Rainforest metropolis casts 1,000 km shadow on wildlife
Rainforest metropolis casts 1,000 km shadow on wildlife
Urban food demand in the Amazon could be hitting wildlife up to 1,000 km away from the city, according to new research. Rapid urbanization in the Brazilian Amazon means over 18 million people are now living in rainforest towns and cities but the impact of this demographic change on wildlife harvested for food, is largely unknown.

Caterpillars key to urban blue tits’ low breeding
Many animal species suffer reduced reproductive success in urban habitats, despite wide-spread supplementation of breeding and feeding opportunities. In some years, the breeding success of city birds is devastatingly low. Biologists have now shown conclusively that in urban blue tits, reduced breeding success is linked to poor nestling diet and in particular to scarcity of caterpillars, their preferred nestling food.

Concrete from wood
Concrete from wood
Researchers from the National Research Programme "Resource Wood" have developed a type of concrete that largely consists of wood. The building material offers the construction industry new possibilities and is based in large part on renewable resources. Houses can be made of wood, as they were in the past - or of concrete, as they are today.

New Studies of Ancient Concrete Could Teach Us to Do as the Romans Did
New Studies of Ancient Concrete Could Teach Us to Do as the Romans Did
?By Glenn Roberts Jr. A new look inside 2,000-year-old concrete - made from volcanic ash, lime (the product of baked limestone), and seawater - has provided new clues to the evolving chemistry and mineral cements that allow ancient harbor structures to withstand the test of time. The research has also inspired a hunt for the original recipe so that modern concrete manufacturers can do as the Romans did.
