Seeing in 3D ‘possible with one eye’, St Andrews study suggests
BBC: The effect of "vivid 3D vision" can be experienced with just one eye, a study has suggested. Researchers at St Andrews University said a method using a small circular hole could have wide implications for 3D technology. The study, published in Psychological Science, also has implications for people who have just one eye or difficulties with double-eye vision. The method was said to create 3D similar to effects used in film-making. Researchers said that current thinking was based on the need for two visual images - one from each eye - to be combined in the visual cortex, creating a sense of depth.

Are you okay? You smell like cytokines.
Nurses and hospice workers say they can smell the final approach of death. Not with sudden death, but with the slow march toward the grave, the body’s systems begin to shut down and metabolism changes, so that breath and skin and fluids give off a distinctive odor that signals the end is near. This is not surprising. In fact it’s more perplexing that deadly diseases don’t announce their presence earlier. From an evolutionary perspective, it would be more advantageous if we could all detect early warning signals, olfactory cues that the immune system is gearing up to ward off a new and threatening disease. Psychological scientists call this the behavioral immune response.

The study is published in Psychological Science, a journal of the Association for Psychological Science. “Context is important,” says psychological scientist and lead researcher Allison Troy of Franklin & Marshall College.

No Conflict: Transparency and Morals
Consider this scenario: You have been sick for some time, more debilitated by the month, and doctors are scratching their heads. Finally, in pain and exhausted, you find a specialist who figures it out. Your ailment is very serious, but the good news is that it can be treated with a new drug. The doctor writes a prescription, but as he hands it to you, he says: “Just so you know, the company that makes this drug also funds a research project of mine.” This is a classic conflict-of-interest, and most people would applaud this physician for voluntarily disclosing his personal interest here.
