Five of the best eco friendly shampoos

All are surfactant, pollutant and paraben free but which eco shampoo is best? Ruth Styles put them to the test Much has been said and written about surfactants in shower gels and dodgy colorings in lipstick, but one beauty product that is commonly overlooked is shampoo. But shampoo and other haircare products are one of the beauty industry’s biggest earners, with some to be found in every bathroom in the country. Not surprisingly, annual sales figures are impressive, with haircare worth around £712 million a year, 41 per cent of which comes from shampoo.

The Impact of a Meteorite Storm

Meteorites have been hitting the Earth since the beginning of time. Yet much is not known of what happens when they hit. Seeking to better understand the level of death and destruction that would result from a large meteorite striking the Earth, Princeton University researchers have developed a new model that can not only more accurately simulate the seismic fallout of such an impact, but also help reveal new information about the surface and interior of planets based on past collisions.

The Strong Woodpecker Head

Banging you head against the wall is not to be recommended because it sort of hurts. Yet the woodpecker does it every day and seems content and happy. Woodpeckers are able to peck at a tree trunk at a high speed (6-7 meters per second), resulting in intense deceleration forces upon impact, without sustaining any brain injury. Why precisely this can be done without injury was investigated by Yubo Fan of Beihang University in Beijing and Ming Zhang of Hong Kong Polytechnic University. The results may lead to better ways to prevent head injuries in humans.

Future Migrations in an Environmentally Uncertain World

There are several major forces at play in today's world. Two forces involved with the migrations of people include globalization and mass exodus from the countryside to cities. Another major force, climate change, is playing an ever greater role, affecting societies with extreme droughts, floods, and other dangers. How will future migrations be affected by this force? A new report by a team of experts including Prof. David Thomas and Prof. Stefan Dercon of Oxford University believes that the challenges associated with migrations and environmental change are underestimated. The report concludes that many will emigrate from environmentally vulnerable places, but some may be trapped, and others may actually move closer to the danger.

A Green Super Yacht on Steroids?

There was the Super Nova 60, the world’s first carbon neutral megayacht. Then there was the 72-foot Emax Excalibur, which represented the first step in the maritime industry towards the production of post-carbon yachts. But forget about those – the folks at Sauter Carbon Offset Design and their building partners Ned Ship Group say the latest in their series of green yacht concepts is "the fastest and greenest superyacht in the world."

Water and the Evolution of Planetary Systems

Using data from the Herschel Space Observatory, astronomers have detected for the first time cold water vapor enveloping a dusty disk around a young star. The findings suggest that this disk, which is poised to develop into a solar system, contains great quantities of water, suggesting that water-covered planets like Earth may be common in the universe. Herschel is a European Space Agency mission with important NASA contributions.

Revolutionary Oil Skimmer Nets $1 Million X Prize

A breakthrough in oil cleanup technology allows crews to skim spilled oil off the water's surface at a much faster rate. The new device wasn't developed by Exxon, BP or any of the major oil companies — it's the work of Elastec/American Marine, based in Illinois. And the design won the company a rich award from the X Prize Foundation.

WWF calls for ban on pet tigers

WASHINGTON, DC, October 20, 2011 – The tragic situation in Ohio has prompted World Wildlife Fund (WWF) to today call for a ban on private ownership of tigers. There are more tigers in captivity in the United States (an estimated 5,000) than there are in the wild (as few as 3,200). The vast majority of captive tigers in the U.S. reside in private hands, not in accredited zoos or circuses, which are well regulated.

California approves carbon market rules

California regulators on Thursday approved final regulations for a carbon market that is one of the biggest U.S. responses to climate change. The state believes the market for greenhouse gases, which starts in 2013, will let it address global warming in a low-cost way and become the center of alternative energy industries, like solar, although some businesses fear higher energy prices. The most populous U.S. state is moving ahead with the plan years after federal regulators rejected a similar idea for the nation, partly on concerns of the effect on businesses. The California Air Resources Board voted 8-0 to adopt the market regulations, which officials said are critical to the state's goal of cutting carbon emissions to 1990 levels by 2020 -- about a 22 percent reduction from forecasted business-as-usual output. Power companies and factories will be able to trade a gradually decreasing number of permits to emit carbon dioxide and other greenhouse gases under the so-called cap-and-trade plan, which counts on market forces leading companies to find the cheapest way to cut emissions.

In the News: Scientists raise estimate of humpback whale numbers

Scientists have increased their estimate of the number of humpback whales in the North Pacific Ocean, according to a report published in the journal Marine Mammal Science. The revised estimate follows analysis of data compiled in 2008 as part of the largest survey ever undertaken to assess humpback whale populations in the North Pacific.
