Study shows smokers are less intelligent

A study of over 20,000 Israeli military recruits suggests that smokers have lower IQs than non-smokers.
Reuters reports on the Israeli study, which takes a different approach to previous studies by attempting to exclude subjects with mental and behavioral problems.
To better understand the smoking-IQ relationship, the researchers looked at 20,211 18-year-old men recruited into the Israeli military. The group did not include anyone with major mental health problems, because these individuals are disqualified from military service.

According to the findings, the average IQ for non-smoking men was 101 and 94 for those who smoke, with a steady decrease in IQ the more the subjects smoked.
Researchers concluded that less intelligent people are more likely to smoke, but not that smoking actually causes a drop in IQ.

UK forest sell-off update: Public outcry shelves govt plan
The UK government has put its plans to sell off vast tracts of publicly owned forestland on hold. The scheme to privatize 258,000 hectares or 1,000 square miles of forest is part of the Conservative-Liberal Democrat coalition government’s harsh program of spending cuts, tax hikes and other actions with the expressed aim of lowering the UK’s large budget deficit. According to a BBC report, the British government is currently allowed to sell of 15% of public forests per public spending period –...
5 Eco Hacks for getting rid of pimples
Baking Soda Make a paste of baking soda and water, then put some directly on the pimple. Leave it on for a few hours, preferably overnight and ideally avoid walking abouts in public. The paste will dry over night, reduce inflammation, and naturally remove pus from the pimple. Ice Just like how you might use ice on a sprained or twisted ankle, bruises, and other injuiries, you can also use ice on pimples. Applying ice for about 15 minutes should help reduce inflammation. Tooth...
Video: Cuba builds eco-homes for hurricane victims
Cuba is using local, low cost, eco-friendly materials to rebuild houses for many who lost their homes due to hurricanes. In 2008 three hurricanes successively tore through Cuba, causing an estimated $10 billion in damages. Many Cubans were left homeless by the severe storms. Cuba's CIDEM research and development institute found an innovative solution for rebuilding sturdier homes for hurricane victims using locally sourced, inexpensive 'eco materials'. CIDEM works with the Cuban government and receives the majority of its funding from Switzerland...
Illegal Chinese medicine trade fuels brutal rhino poaching
Africa’s rhinos are facing a constant threat due to poachers and trophy hunting. The increasing demand for rhino horn used in traditional Chinese medicine – especially in new markets such as Vietnam – is fueling an illegal trade involving corruption and organized crime. In a recent poaching attack in the KwaZulu-Natal province of South Africa, poachers entered a wildlife reserve via helicopter and cut the horns off of a drugged white rhino with a chainsaw. The rhino miraculously survived the brutal...
Global pollution: Death is in the air
Just as the UN published figures that global access to clean water has improved, already surpassing their goals set for 2015, a new OECD report predicts that air pollution is set to become the leading environmental cause of premature death. So the Organization for Economic Co-operation and Development, whose raison d’être is economic growth, is warning that industrialization, which has worked hand in glove with economic growth and market-based economics, is killing more and more people by polluting the air. Previous UN...
Gigantic Iceberg Drifting off Antarctica towards Australia
Nine years ago a 54 square-mile (about 1,700 km) iceberg broke of an Antarctic ice shelf. Today, almost ten years later, this gigantic chunk of ice is drifting towards western Australia while similarly large icebergs have also been spotted off the coast of New Zealand. While the iceberg was “trapped” for several years east of the Mertz Glacier, it recentlybegan its latest drift northeast. It’s been more than a 100 years since such a big iceberg ever drifted so far away...
Green Home Makeover: Helpful and Concise Environmental Videos from National Geographic
A kind of video supplement to National Geographic’s Green Guide, Green Home Makeover is a series of videos with helpful hints on making your home more energy conscious and environmentally friendly. National Geographic’s websites can be a bit tricky to navigate and use a Flash platform (so clicking the ‘back’ button won’t help) but once you familiarize yourself with the many sections available, you will find a vast wealth of Green resources. There is no video section on the Green...
Sound and fury: Thoughts on climate science and the media
A cool thing about science is that – just like the climate – it's always changing. It isn't that 'reality' changes in the sense that the fundamental laws of physics somehow alter, but what does change, continually and without exception, is how we understand and interpret phenomena. This is the normal progressive route that all science takes – physical, medical, social, humanistic, whatever. Science and the scientific method are not things after all, but mutable practices which are continually built...
European CO2 emissions could be reduced with 95 percent by 2050
According to the recently released yearly study Energy Revolution (conducted by Greenpeace and the EREC – European Renewable Energy Council) Europe could reduce it’s CO2 emissions with 95 percent by 2050. The results of the study show that Europe could achieve this spectacular reduction in CO2 emissions by producing up to 97 percent of its electricity and 92 percent of its total energy needs from renewable energy sources. But to achieve these numbers a real energy revolution is required. As an...
Wine producers should stick a cork in it – for environmental reasons, of course
According to an October 5th article in the London Times, bottle caps aren't all that recyclable. Admittedly, I've never really known what to do with bottle caps, metal jar lids, and other little bits and bobs that perhaps don't strictly fit into one of the paper/plastic/glass/metal categories. Where I live in the U.K. all the recycling just goes into one common bin anyway, to be later sorted out at recycling stations or plants. It was the same when I lived...
