With the COP15 conference fast approaching, the world's political leaders are gearing up to hash out a global agreement that will save us from ever increasing greenhouse gas emissions and the unstoppable climate change that will follow.

New research published this week in Geophysical Research Letters, however, may complicate their plans. The new research, conducted by a professor of Earth Science at the University of Bristol, shows that the balance between the airborne and the absorbed fraction of CO2 has stayed approximately constant since 1850, despite emissions of CO2 having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now.

After the successful introduction of myspace, facebook, twitter and however many other social networking sites that now exist, researchers at London's Natural History Museum have created a social networking tool called 'Scratchpads' just for natural historians. The platform is designed to get specialists together to share their data and prevent the discipline from being buried under a landslide of painstakingly collected data that isn't always used.

If you're sore from a strenuous workout or your thumb is pulsating because you hit it with a hammer, look at a pretty picture or listen to your favorite song. It just might help you cope with whatever unpleasant feeling you're experiencing . That's the conclusion of a study published in the Proceedings of the National Academy of Sciences that looked at the connection between human emotions and physical pain.

"Emotions – or mood – can alter how we react to pain since they're interlinked," says lead author Mathieu Roy. "Our tests revealed when pain is perceived by our brain and how that pain can be amplified when combined with negative emotions."

Scientists say they can now tell the condition of an old book by its odor. In a report published in Analytical Chemistry, a team of researchers describe development of a new test that can measure the degradation of old books and precious historical documents on the basis of their aroma. The non-destructive "sniff" test could help libraries and museums preserve a range of prized paper-based objects, some of which are degrading rapidly due to advancing age, the scientists say.

The new technique — an approach called "material degradomics" — analyzes the gases emitted by old books and documents without altering the documents themselves. The scientists used it to "sniff" 72 historical papers from the 19th and 20th centuries.

If rehospitalization is considered when grading health care, America's system is not all it is cracked up to be. Proof? New evidence indicates almost a quarter of heart failure patients with Medicare are back in the hospital within a month after discharge, researchers report today in Circulation: Heart Failure.

Each year, from 2004 through 2006, more than a half million Medicare recipients over age 65 went to the hospital for heart failure and were discharged alive.  And each year, about 23 percent returned to the hospital within 30 days – signaling a need to improve care, researchers said.  Readmission rates for all causes were almost identical all three years.

With Tropical Storm Ida currently dumping rain and high winds in the southeast we wanted to talk about coastal hazards.   Coastal hazards along America's shorelines threaten a significant percentage of the U.S. population.    Here is a quick beach quiz to find out how much you know about your risks.

b)    9,000
c)    5,500
d)    7,500

This week, scientists from Australia and the UK are taking a break from their professional research to wave their fists angrily at the alcohol industry. In hopes of reducing alcohol abuse, they are calling for a new approach to the debate over whether alcohol industry sponsorship of sports increases drinking among sports participants.  They want to shift the burden of proof to the alcohol industry.

The debate over sports sponsorship saw renewed activity last year when the findings of a 2008 New Zealand study among sports participants showed that those who received alcohol industry sponsorship – especially in the form of free or discounted alcohol – drank more heavily than those not in receipt of such sponsorship.
