A large Australian study of more than 200,000 people has provided independent confirmation that up to two in every three smokers will die from their habit if they continue to smoke.
The research, published today in the international journal BMC Medicine, is the first evidence from a broad cross-section of the population to show the smoking-related death toll is as high as two thirds.
Botanists from Trinity College Dublin have made a breakthrough discovery that could save barley farmers sleepless nights and millions of Euro each year: naturally occurring plant-friendly fungi prevent crop-ravishing diseases from spreading, and also aid plant survival in testing environmental conditions. Importantly, these amazing little organisms cause no harm to the plant roots in which they take up their abode. However, their gift of immunity against common seed diseases greatly reduces the need for farmers to spray environmentally damaging chemicals, which can affect ecosystems in a plethora of negative ways.
By studying African lake sediments from the past 20,000 years, scientists are learning more about abrupt climate shifts, advancing their understanding of changing weather patterns. In a recent paper published in Nature Geoscience, co-author on an NAU assistant professor Nicholas McKay analyzes core samples from Lake Bosumtwi in Ghana. The isolated lake was formed by a meteor and sits like a bowl on the landscape giving scientists a clear view of environmental changes.
Mediante el estudio de sedimentos de lagos africanos de los últimos 20,000 años, los científicos están aprendiendo más sobre los cambios climáticos abruptos, obteniendo una mayor comprensión de los cambios del clima.
En un artículo reciente publicado en la revista Nature Geoscience, el profesor Nicholas McKay analiza muestras del núcleo del lago Bosumtwi en Ghana. El lago fue formado por un meteorito y luce como un cuenco en el paisaje dando a los científicos una visión clara de los cambios ambientales.
The day I first set foot in a tropical rainforest, in Malaysia in the early 1980s, I experienced something profound. From the echoes of gibbons calling from the canopy in the early morning mist to the iridescent flash of a bird in a beam of sunlight, rainforests are a sensory delight as well as a marvel to anyone’s scientific curiosity.
As I subsequently watched these forests dwindle and, in some cases, vanish, I have felt an equally profound sense of loss and a nagging guilt that I was somehow part of the story, because I had done little to remedy the situation.
