Chemical weapon and radiation fear at Scottish RAF base

The Ministry of Defence (MOD) may have sold off land contaminated with chemical weapons and radioactive material buried at an RAF base in North-East Scotland, according to reports. The Scottish Environment Protection Agency (Sepa) is already investigating radioactive contamination at RAF Kinloss, believed to be from Second World War aircraft coated in radium and buried at the site.

1,000 Years of Climate Data Confirms Australia’s Warming

In the first study of its kind in Australasia, scientists have used 27 natural climate records to create the first large-scale temperature reconstruction for the region over the last 1000 years. The study was led by researchers at the University of Melbourne and used a range of natural indicators including tree rings, corals and ice cores to study Australasian temperatures over the past millennium and compared them to climate model simulations

New Jersey Takes Slow, Steady Approach to Offshore Wind

The international wind power industry is watching Washington, DC to see if lawmakers will extend the federal production tax credit (PTC) for wind power. But their eyes are also focused on Trenton, the state capital of New Jersey, to see if state regulators there will help launch America's long-awaited offshore wind energy industry.

Tropic Atmospheric Circulation

An University of California - Riverside led team has identified black carbon and tropospheric ozone as the most likely drivers of large-scale atmospheric circulation change in the Northern Hemisphere tropics zone. While stratospheric ozone depletion has already been shown to be the primary driver of the expansion of the tropics in the Southern Hemisphere, the researchers are the first to report that black carbon and tropospheric ozone are the most likely primary drivers of the tropical expansion observed in the Northern Hemisphere.

Paper or Plastic?

Cities in a number of Asian countries, including China, Hong Kong, India, Indonesia, Nepal, Pakistan, the Philippines, Singapore and Taiwan, are currently on the warpath against plastic shopping bags. The cities have passed local laws that ban such bags, on the basis that they clog sewers and drainage canals, cause street flooding, choke animals and are responsible for other forms of environmental damage. China and Taiwan, for example, impose heavy fines on violators. Other countries are appealing for a switch to the production and use of biodegradable bags. But this misses the point. People do not object to using biodegradable bags, and consider them a welcome return to the traditional practice of using shopping baskets and bags made from locally available materials — such as jute, abaca and cloth — that are less harmful to the environment.

Taste and Temperature

Some people like food or beverages hot and some like them cold. What's the difference? Can the temperature of the food we eat affect the intensity of its taste? It depends on the taste, according to a new study by Dr. Gary Pickering and colleagues from Brock University in Canada. Their work shows that changes in the temperature of foods and drinks have an effect on the intensity of sour, bitter and astringent tastes but not sweetness. Their work is published online in Springer's Chemosensory Perception journal. Humans receive tastes through sensory organs called taste buds concentrated on the top of the tongue. Taste is sensed through taste cells, which are known as taste buds. There are about 100,000 taste buds that are located on the back and front of the tongue. Others are located on the roof, sides and back of the mouth, and in the throat.

Cars That Run on Natural Gas – Alternative Fuels

Find out how an alternative fuel used all over the world may find its way into American vehicles. Natural gas is abundant, clean and already a part of our everyday lives—and it may be the next big alternative fuel. In the world of alternative fuels, electric, hydrogen and even hybrid vehicles get most of the attention. Not many people are aware of another alternative automotive fuel that burns cleaner than gasoline, is found abundantly in the United States and is already in heavy use around the world: natural gas. Natural gas is by no means a new fuel; it’s been used to heat homes and cook food in gas stoves for more than a century. But only recently have automotive technicians begun exploring the possibility of using natural gas as an alternative to gasoline in automobiles here in the United States. When used in automobiles, natural gas comes in two forms: Compressed natural gas (CNG) Liquefied natural gas (LNG) Both forms require storage in cylinders that are often located in the trunk of the vehicle. When being burned by an engine, natural gas works very similarly to gasoline; vehicles that run on natural gas will have spark plug timing and compression optimized for that type of fuel.

Natural sinks still sopping up carbon

Earth's ecosystems keep soaking up more carbon as greenhouse gases accumulate in the atmosphere, new measurements find. The research contradicts several recent studies suggesting that "carbon sinks" have reached or passed their capacity. By looking at global measurements of atmospheric carbon dioxide, the new work calculates instead that total sinks have increased roughly in line with rising emissions.

Hotels charge you (for free)

Curious about electric cars? On your next vacation, give one a test drive—and instead of paying high gas prices, charge up for free. Major car rental companies, which have been offering hybrid vehicles for years, are now getting into the electric car (EV) market. And an ever-growing number of hotels, resorts, and even B&Bs are adding free electric-car charging stations to entice guests to get off the grid and plug in their cars when they travel.

Report: Global Biodiversity Down 30 Percent in 40 Years

The world's biodiversity is down 30 percent since the 1970s, according to a new report, with tropical species taking the biggest hit. And if humanity continues as it has been, the picture could get bleaker. Humanity is outstripping the Earth's resources by 50 percent — essentially using the resources of one and a half Earths every year, according to the 2012 Living Planet Report, produced by conservation agency the World Wildlife Fund (WWF).
