A roadmap for calibration and validation

The volume of data acquired by more than 50 Earth observation satellites is increasing at an exponential rate and is providing unprecedented synoptic views of our planet. Because these satellites often use different methodologies, using data for trend analysis and environmental monitoring can be difficult, making it essential to establish globally-recognized guidelines for calibration and validation processes.

1. Why we are such terrible judges of the relationship between price and quality
   10-18-2006 · EurekAlert!
   Past research has demonstrated that both experts and novices make notoriously poor judgments. A new study examines the mental processes behind our flawed assessments, a recurring issue in many areas of consumer research as well as in other areas of psychology and psychiatry. When it comes to the relationship between price and quality, Arul Mishra and Dhananjay Nayakankuppam (University of Iowa) argue that rather than an insensitivity to data -- poor calibration -- human judges are simply inconsistent.

2. New mechanism underlying pain found
   10-15-2006 · EurekAlert!
   Researchers at Johnson & Johnson Pharmaceutical Research & Development (J&JPRD) today announced that they have discovered a new molecular mechanism that may underlie neuropathic pain. The clearer understanding of the root-cause of chronic neuropathic pain, and the preclinical validation of new targets for pharmaceutical therapies shown in this research, together present an opportunity for the development of new ways to treat the severe pain associated with such common conditions or diseases as sciatica, diabetic neuropathy and shingles.

4. Learning to live with oxygen on early Earth
   10-16-2006 · EurekAlert!
   Scientists at the Carnegie Institution and Penn State University have discovered evidence showing that microbes adapted to living with oxygen 2.72 billion years ago, at least 300 million years before the rise of oxygen in the atmosphere. The finding is the first concrete validation of a long-held hypothesis that oxygen was being produced and consumed by that time and that the transition to an oxygenated atmosphere was long term.
