The feeling of security and the reality of security don't always match, says computer-security expert Bruce Schneier. He explains why we spend billions addressing news story risks, like the "security theater" now playing at your local airport, while neglecting more probable risks - and how we can break this pattern.

CO2 capture by means of amines is considered to be the most appropriate method to quickly begin with CO2 removal. During this capture process, some of the amines escaping the recycling process will be emitted into the air and will also form other compounds such as nitrosamines and nitramines. The Norwegian Institute of Public Health (NIPH) was commissioned by the Climate and Pollution Agency (Klif) to assess whether these new emissions are harmful to health - particularly in terms of the cancer risk to the general population. The results of the risk assessments were submitted recently.

Research by McGill Sociology Professor Eran Shor, working in collaboration with researchers from Stony Brook University, has revealed that unemployment increases the risk of premature mortality by 63 per cent. Shor reached these conclusions by surveying existing research covering 20 million people in 15 (mainly western) countries, over the last 40 years.

A new study has discovered viruses in almost 40 % of more than 1,400 bathing water samples collected from coastal and inland areas in 9 European countries. The findings, presented in the journal Water Research, suggest that the presence of infectious adenoviruses and noroviruses in water samples 'could pose a risk to health.'

For more than 40 years, the International Union for Conservation of Nature (IUCN) has published the Red List of Threatened Species describing the conservation status of various species of animals. They are now also including plants in their lists and the picture they present is dramatic. According to recent estimates, around 20 per cent of flowering plants are currently at risk of extinction - though the exact number is unknown since such a small proportion of plant species has even been measured.

The explosive growth of cities worldwide over the next two decades poses significant risks to people and the global environment, according to a meta-analysis published today in Plos One.

"Research released today shows that within the next 10 years large parts of Asia can expect increased risk of more severe droughts, which will impact regional and possibly even global food security."

Polar ecosystems could be at risk from the spread of toxic cyanobacteria if the climate continues to warm, say scientists.

Research being carried out at Carlos III University of Madrid analyzes the key factors in climate change and the risks to public policies that it implies. This study approaches the issue from the perspective of Sociology, Economics and Law.

In the first study of its kind, researchers have linked a natural global climate cycle to periodic increases in warfare. The arrival of El Niño, which every three to seven years boosts temperatures and cuts rainfall, doubles the risk of civil wars across 90 affected tropical countries, and may help account for a fifth of worldwide conflicts during the past half-century, say the authors. The paper, written by an interdisciplinary team at Columbia University's Earth Institute, appears in the current issue of the leading scientific journal Nature.

Reports of sleeping air traffic controllers highlight a long-known and often ignored hazard: Workers on night shifts can have trouble concentrating and even staying awake.

The world next week remembers 25 years since the worst nuclear accident in history at Chernobyl, haunted by fears that the Japan earthquake has shown again the risk of atomic power sparking apocalypse.

The first research to actively analyze adult male sea turtles (Caretta caretta) using satellite tracking to link geography with pollutants has revealed the potential risks posed to this threatened species by manmade chemicals. The research, published today in Environmental Toxicology and Chemistry, examines the different levels of chemicals in the blood of both migratory and residential turtles.

The "colour" of our environment is becoming "bluer", a change that could have important implications for animals' risk of becoming extinct, ecologists have found. In a major study involving thousands of data points and published this week in the British Ecological Society's Journal of Animal Ecology, researchers examined how quickly or slowly animal populations and their environment change over time, something ecologists describe using "spectral colour".

Scientists of earth, sea and sky, scholars of law, politics and philosophy: In three intense days cloistered behind Chicheley Hall's old brick walls, four dozen thinkers pondered the planet's fate as it grows warmer, weighed the idea of reflecting the sun to cool the atmosphere and debated the question of who would make the decision to interfere with nature to try to save the planet. The unknown risks of "geoengineering" - in this case, tweaking Earth's climate by dimming the skies - left many uneasy. "If we could experiment with the atmosphere and literally play God, it's very tempting to a scientist," said Kenyan earth scientist Richard Odingo. "But I worry."

A new report on young people's use of social networking and cyber safety reveals that young people may be more aware and better able to manage online risks than their parents commonly think.

The European Union's Working Party on Data Protection has issued five recommended requirements for the protection of personal privacy in a time of Smart Meters in the home (PDF). Below is what the group says needs to happen in order to gain the benefits of Smart Metering data while minimizing the risk and cost to personal privacy. 

As scientists continue to be baffled over the recent decline in bee populations around the world, a new model developed by Dr Andrew Barron at Macquarie University in collaboration with David Khoury and Dr Mary Myerscough at the University of Sydney, might hold some of the answers to predicting bee populations at risk.

Germany is determined to show the world how abandoning nuclear energy can be done.
