With spring now fully sprung, a new study by University of Wisconsin–Madison researchers shows that buds burst earlier in dense urban areas than in their suburban and rural surroundings. This may be music to urban gardeners’ ears, but that tune could be alarming to some native and migratory birds and bugs.
Las células inmunes juegan un papel esencial en el mantenimiento y reparación de nuestros cuerpos. Cuando nos herimos a nosotros mismos, las células inmunes montan una respuesta inflamatoria rápida para protegernos contra las infecciones y ayudar a curar el tejido dañado.
La investigadora principal, la doctora Helen Weavers, de la Facultad de Ciencias Biomédicas, dijo: "Si bien esta respuesta inmune es beneficiosa para la salud humana...
Over fifty percent of the United States energy comes from coal and petroleum based fuels. Powering a nation in which the average person uses the amount of energy in 15,370 lbs of coal or 165,033 sticks of dynamite in a year is not sustainable. When thinking of a solution, the well-known renewable energy source that most likely comes to mind is solar power.
Solar panels are an impervious surface. Impervious surfaces already take up 32,868.61 square miles of roads, parking lots, driveways, and more. These surfaces displace rainwater to surrounding areas and have great impacts on the water table and soil quality. Utilizing already cleared land rather than clearing more would be beneficial to the environment, as solar fields require large amounts of cleared land.
A new analysis of global data related to wildfire, published by the Royal Society, reveals major misconceptions about wildfire and its social and economic impacts.
Durante años, uno de los principales argumentos que se han hecho en contra de los cultivos transgénicos (OGM) es el temor de que, mediante la manipulación de ADN de una planta, potencialmente se podría causar problemas de salud para los consumidores. Es una preocupación comprensible, sin embargo, el consenso científico actual parece ser innegable: Cualesquiera que sean las fallas que los cultivos transgénicos puedan tener, son seguros para el consumo humano.
Long-term exposure to air pollution has been linked to an increased risk of heart disease, but the biological process has not been understood. A major, decade-long study of thousands of Americans found that people living in areas with more outdoor pollution —even at lower levels common in the United States — accumulate deposits in the arteries that supply the heart faster than do people living in less polluted areas. The study was published May 24 online in The Lancet.
