Carbon nanodots do an ultrafine job with in vitro lung tissue — ScienceDaily

Epidemiological studies have established a strong correlation between inhaling ultrafine particles from incomplete combustion and respiratory and cardiovascular diseases. Still, relatively little is known about the mechanisms behind how air particulates affect human health. New work with carbon nanodots seeks to provide the first model of how ultrafine carbon-based particles interact with the lung tissues. […]

Evaluating the contribution of black carbon to climate change — ScienceDaily

Black carbon refers to tiny carbon particles that form during incomplete combustion of carbon-based fuels. Black carbon particles absorb sunlight, so they are considered to contribute to global warming. However, the contribution of black carbon to the heating of the Earth’s atmosphere is currently uncertain. Models that can accurately assess the warming effect of black […]

SpaceX Falcon 9 rocket launches Canadian comsat

Dodging cloudy weather, a SpaceX Falcon 9 rocket thundered to life and streaked away from Cape Canaveral early Monday morning, lifting a Canadian communications satellite into orbit while the booster’s first stage plunged back to Earth, settling to an on-target touchdown aboard an off-shore droneship. It was the 16th SpaceX launch so far this year, […]

Risk gene for Alzheimer’s may aggravate neurological effects of air pollution in children — ScienceDaily

There is growing evidence that exposure to air pollution adversely affects cognitive and behavioural development in children. However, the mechanisms underlying this association are, as yet, unknown. Now, the findings of a new study from the Barcelona Institute for Global Health (ISGlobal), an institute supported by the “la Caixa” Banking Foundation, suggest that the ε4 […]

Microorganisms, including potential pathogens, travel from sea to land via fog — ScienceDaily

Fog can act as a vector for microbes, transferring them long distances and introducing them into new environments. So reports an analysis of the microbiology of coastal fog, recently published in the journal Science of the Total Environment. Co-author Kathleen Weathers, a Senior Scientist at Cary Institute of Ecosystem Studies, explains, “Fog’s role in transporting […]
