Volcanic eruptions are one of the most important natural causes of climate change, playing a leading role over the past millennium. Injections of sulfate aerosols into the lower stratosphere will reduce the incoming solar radiation, which in turn cooling the surface. As a natural external forcing to the Earth’s climate system, the impact of volcanic aerosol on the climate has been of great concern to the scientific society and the public.
A new study appearing online today from The American Journal of Psychiatry finds that elevated pesticide levels in pregnant women are associated with an increased risk of autism among their children.
Researchers have found declines in the number and diversity of bird populations at nine sites surveyed in northern New Mexico, where eight species vanished over time while others had considerably dropped.
Watermelon rind, usually discarded as waste, has been shown by researchers in Pakistan to be capable of cheaply and efficiently removing arsenic from groundwater.
New research from Indiana University suggests that computer models used to predict the spread of epidemics from climate change -- such as crop blights or disease outbreaks -- may not take into account an important factor in predicting their severity.
Mathematics can help public health workers better understand and influence human behaviours that lead to the spread of infectious disease, according to a study from the University of Waterloo.
Socio-economic position determines the environmental hazards—such as air pollution and noise—that pregnant women are exposed to in urban areas, although the nature of the association varies from city to city. This was the main conclusion of a new study conducted with the participation of the Barcelona Institute for Global Health (ISGlobal), a centre supported by the ”la Caixa” Banking Foundation.
Forests in the eastern United States may have had it easy compared to their western counterparts, with the intense, prolonged droughts and wildfires that have become typical out west in recent years. But as the climate changes over time, eastern forests are also likely to experience longer droughts. And although wildfires are comparatively rare, prescriptive fires are increasingly used in the east. How will these forests fare in the future? A new study from the University of Illinois provides answers.
Can a new type of transparent gel, made from readily-available beer waste, help engineers build greenhouses on Mars?
In dark alleys of the Pacific and Indian oceans, new research shows some of the deadliest, armored fishes on the planet are packing switchblades in their faces.
