Study: 'E-waste pollution' a threat to human health - 0 views
-
In addition to its damaging effect on the environment and its illegal smuggling into developing countries, researchers have now linked e-waste to adverse effects on human health, such as inflammation and oxidative stress - precursors to cardiovascular disease, DNA damage and possibly cancer.
Experts quantify melting glaciers' effect on ocean currents - 0 views
-
A team of scientists from the University of Sheffield and Bangor University have used a computer climate model to study how freshwater entering the oceans at the end of the penultimate Ice Age 140,000 years ago affected the parts of the ocean currents that control climate.
20 former world leaders discuss looming water crisis - 0 views
-
Twenty former heads of state, including former US president Bill Clinton, warned Tuesday of an impending "water crisis" and agreed to establish a panel that will tackle a worldwide leadership gap on the issue.
Fungus destroying amphibian populations at higher rate than habitat destruction - 0 views
-
According to a new report published in the Proceedings of the National Academy of Sciences, human development and habitat loss are not the main contributor to the population decline of many amphibian species. In actuality, that human encroachment on natural habitat many actually be saving some of them.
From seawater to freshwater with a nanotechnology filter - 0 views
-
In this month's Physics World, Jason Reese, Weir Professor of Thermodynamics and Fluid Mechanics at the University of Strathclyde, describes the role that carbon nanotubes (CNTs) could play in the desalination of water, providing a possible solution to the problem of the world's ever-growing population demanding more and more fresh drinking water.
Food security in 2050 on a global scale achievable but greatly challenging - 0 views
-
With today's crops, it would be possible to feed the 2050 global population of nine billion people. But agricultural land will have to be used optimally. And this demands solid economic and institutional preconditions. Food prices will probably eventually rise. This was discussed by Professor Martin van Ittersum on 12 May 2011 at the ceremony at which he accepted the post of Professor of Plant Production Systems with a personal chair at Wageningen University.
UF develops method to make plastic from discarded plant material - 0 views
-
Plastic may compete with paper in the grocery line, but it doesn't have to compete with the world's food supply, according to University of Florida researchers. They've developed a way to produce plastic that doesn't use valuable natural resources, such as food or fuel, for raw materials. The new method uses a strain of bacteria to create bioplastic from discarded plant material, such as yard waste.
Noise research to combat 'wind turbine syndrome' - 0 views
-
University of Adelaide acoustics researchers are investigating the causes of wind turbine noise with the aim of making them quieter and solving 'wind turbine syndrome'.
Cool temperatures, wet weather affecting blueberry crop - 0 views
-
The recent cool, wet conditions in Maine may delay the state's blueberry crop for about a week, according to David Yarborough, University of Maine Cooperative Extension's blueberry specialist and UMaine professor of horticulture.
Central China drought worst in over 50 years: reports - 0 views
-
Central China's worst drought in more than 50 years is drying reservoirs, stalling rice planting, and threatens crippling power shortages as hydroelectric output slows, state media said Wednesday.
Changes in weather patterns creating more severe storms - 0 views
-
John Harrington Jr., professor of geography, is a synoptic climatologist who examines the factors behind distinctive weather events. He credits the increased tornado production this year to jet stream patterns in the upper atmosphere. The patterns have created synoptic events such as the April tornado outbreak in Alabama and recent tornado in Joplin, Mo. While these events are not unprecedented, they are significant, he said.
Forest fragmentation threatens Europe, species: UN - 0 views
-
Fires, felling and agriculture are whittling Europe's forests down into isolated patches, threatening to speed up desertification and deplete wildlife, a UN report warned Tuesday.
Climate change allows invasive weed to outcompete local species - 0 views
-
Yellow starthistle already causes millions of dollars in damage to pastures in western states each year, and as climate changes, land managers can expect the problem with that weed and others to escalate.
Global warming may affect the capacity of trees to store carbon, study finds - 0 views
-
global warming may affect the capacity of trees to store carbon by altering forest nitrogen cycling, concludes a study led by Jerry Melillo, Distinguished Scientist at the Marine Biological Laboratory (MBL) Ecosystems Center, and published this week in Proceedings of the National Academy of Sciences.
Study: Biodegradable products may be bad for the environment - 0 views
-
Research from North Carolina State University shows that so-called biodegradable products are likely doing more harm than good in landfills, because they are releasing a powerful greenhouse gas as they break down.
Physicists describe how to make time-reversed light pulses - 0 views
-
By taking advantage of the properties of periodic systems, physicists have described how to efficiently time-reverse ultrashort electromagnetic pulses. Since a time-reversed pulse evolves as if time runs backwards, time reversal eliminates any distortions or scattering that occurred at earlier times, regardless of the medium the pulse has propagated through.
UN aims for biodiversity treaty by July 2012 - 0 views
-
A global treaty on the harvesting of genetic resources will probably be ratified by July 2012, the UN executive secretary on biological diversity said Tuesday.
Progress in the development of rechargeable batteries through nanotechnology - 0 views
-
Researchers are testing different ways of improving rechargeable batteries for electric vehicles and nanotechnology plays an important role in the development. The aim is to offer batteries that have fast charge and discharge rates as well as high stored energy per mass. This can make electric vehicles a competitive alternative to petrol-powered vehicles.
Measuring the next generation of life-saving pollution sensors - 0 views
-
ew research from the UK's National Physical Laboratory (NPL) is helping Duvas Technologies Ltd (Duvas) to develop improved air quality monitoring instrumentation. Currently over 1bn people a year suffer from respiratory disease associated with pollution, and according to the World Health Organisation, over 3m a year die from its effects. Duvas is planning to help provide technology to understand and address this problem.
