Inflammation and cancer-related gene expression was overcharged by exposure to particulate matter in city air.
I, for one, welcome our new sylvan neighbors.
It also has an ‘evil sister’ project!
Worldwide, more and more people are starting to move from rural areas to urban areas. But nowhere is this as prevalent as in Africa.
It’s not much, but we’re all contributing!
Space — a pretty dusty place.
Tap, tap, microbe map.
The black things – that’s us.
Human social behavior is strikingly governed by laws that describe how the masses congregate or interact one another. Yet, despite the empirical evidence, scientists know very little what stems these mass behaviors. An individual is highly unpredictable, but masses are not (in this respect, Isaac Asimov’s Foundation takes it to the extreme with his fictional psychohistory).
Trees planted along a city street could screen residents from sun and noise – but more importantly, they can also protect them from the polluted air. A new study has shown that tree leaves can capture more than 50% of the polluting particulate matter – the main source of urban pollution and a trigger for disease. In cities, this type
China is the most pollutant country in the world, and as it continues to develop industrially, one can only expect greenhouse gas emissions to grow as well. The country is taking steps towards its ecological rehabilitation, however. The first step was to acknowledge that it faces a dire problem, one whose consequences reverse on the entire world. One of the most interesting green
No other continent in the world (that’s not counting Antarctica) is studied by less ecologists than Africa; that is actually paradoxal, because cities are growing here faster than any other continent on Earth. Just less than a century ago, 5% of people lived in urban areas, while now, almost 40% call a city their home. This rapid growth is causing
Recently, the NASA observatory published some great images of some cities. For a man looking at those cities at night, man’s work seems both impressive and insignificant. But the view would be fantastic: regular patterns of irrigated cropland, straight lines of roads and railways running across continents, reservoirs on river systems, and the cement rectangles of ports and seawalls along
