Brain reacts to fairness as it does to money and chocolate The human brain responds to being treated fairly the same way it responds to winning money and eating chocolate, UCLA scientists report. Being treated fairly turns on the brain's reward circuitry.

Carnegie Mellon studies how climate change impacts food production The old adage, "We are what we eat,'' may be the latest recipe for success when it comes to curbing the perils of global climate warming. Pathogen virulence proteins suppress plant immunity Researchers from the Virginia Bioinformatics Institute (VBI) at Virginia Tech and their colleagues have identified a key function of a large family of virulence proteins that play an important role in the production of infectious disease by the plant pathogen Phytophthora sojae. Synchrotron light unveils oil in ancient Buddhist paintings from Bamiyan The world was in shock when in 2001 the Talibans destroyed two ancient colossal Buddha statues in the Afghan region of Bamiyan. Counting every thought: What consumers see when looking at ads Thought-listing exercises are frequently used by researchers to gauge people's reactions to advertisements. But a new paper in the June 2008 issue of the Journal of Consumer Research from the Wharton School of Business suggests two alternative methods that may more accurately reveal what consumers actually notice. Computer scientists develop solutions for long-term storage of digital data Although the digital age is well under way, one crucial detail remains to be worked out--how to store vast amounts of digital information in a way that allows future generations to recover it. Larger skin lesions appear more likely to be melanomas Skin lesions larger than 6 millimeters in diameter appear more likely to be melanomas than smaller lesions, according to a report in the April issue of Archives of Dermatology, one of the JAMA/Archives journals. The findings suggest that the diameter guidelines currently used by dermatologists to screen for melanoma are useful. When positive thinking leads to financial irresponsibility like compulsive gambling Looking on the bright side can lead to irresponsible financial behavior, reveals a paper from the June 2008 issue of the Journal of Consumer Research. How stereotypes can lead to success Stereotypes can boost as well as hinder our chances of success, according to psychologists from the University of Exeter and St Andrews University.

Scientists test device to track medication adherence in patients with HIV/AIDS Most of us have missed a dose of antibiotic or forgotten to take a daily vitamin. But when the stakes are higher - as they are for people with HIV/AIDS - a skipped pill could mean the difference between health and hazard for the entire population. Cancer could return unless stored ovarian tissue undergoes adequate testing before re-implantation Cancer patients who have been successfully treated for their disease face the prospect of its return if stored ovarian (or testicular) tissue is transplanted back into their bodies without adequate checks, according to researchers at two university hospitals in Israel. Coke or Pepsi? Being distracted can make you more susceptible to ads A can of Coke next to the word "awesome"; a can of Pepsi next to a picture of a happy couple. Seem too basic to be effective advertising" Prior research has shown that reported attitudes towards brands are not affected by such simple juxtapositions. Nasal surgery associated with improvements in quality of life for those with sleep apnea Nasal surgery to remove obstructions from the airway is associated with improvements in quality of life for patients with obstructive sleep apnea and symptoms of nasal blockages. Survival rates appear lower for scalp and neck melanoma than for other sites Individuals with melanoma on their scalp or neck appear less likely to survive for five or 10 years than those with melanoma at other sites, according to a report in the April issue of Archives of Dermatology, one of the JAMA/Archives journals. Effective cancer immune therapy through order in the blood vessels Immune therapies are considered very promising in cancer medicine: Tumor-fighting immune cells are supposed to invade tumor tissue and eliminate cancer cells right there. We are family -- but advertisers often miss the point Even though most Americans think of themselves as part of a family - and many list "being a family" as a top priority - very little is known about how membership in this collective actually affects consumer decisions, from choosing a cell phone plan to remodeling the kitchen to how we display treasured keepsakes.
