Which holds more: A tall, thin glass or a short, fat one?

A fascinating new study from the March 2006 issue of the Journal of Consumer Research explores how our senses interact to gauge volume, with important implications for perception of consumer products and consumption patterns. Specifically, the article argues that "elongation effect" – the common tendency to think that a tall, thin glass holds more than a short, stout glass of equal volume – is reversed when touch is used instead of sight to evaluate how much a container holds. more  

Guilt and fear motivate better than hope

"Smoking pot may not kill you, but it will kill your mother," says an ad from the Partnership for a Drug-Free America. In the first empirical work to examine both stated intentions and actual behavior, researchers argue that this sort of negative message – evoking both fear and guilt – is a far more effective deterrent to potentially harmful behavior than positive hopeful or feel-good messages. more

Hormone linked to good hearing as we age

Researchers have linked a hormone known to adjust levels of key brain chemicals to the quality of our hearing as we age. The more of the hormone that older people have in their bloodstream, the better their hearing is, and the less of the hormone, the worse their hearing is. more  

Study finds some people in pain unlikely to seek treatment

FDA issues public health advisory for Trasylol 

The Food and Drug Administration issued a Public Health Advisory alerting doctors who perform heart bypass surgery, and their patients, that Trasyolol (aprotinin injection), a drug used to prevent blood loss during surgery, has been linked in two scientific publications to higher risks of serious side effects including kidney problems, heart attacks and strokes in patients who undergo artery bypass graft surgery. more

When normal DNA changes shape into Z-DNA, it leads to genetic instability and cancers such as leukemia and lymphoma  

When otherwise normal DNA adopts an unusual shape called Z-DNA, it can lead to the kind of genetic instability associated with cancers such as leukemia and lymphoma, according to a study by researchers at The University of Texas M. D. Anderson Cancer Center. more

Mice lacking social memory molecule take bullying in stride

The social avoidance that normally develops when a mouse repeatedly experiences defeat by a dominant animal disappears when it lacks a gene for a memory molecule in a brain circuit for social learning, scientists funded by the National Institutes of Health’s (NIH) National Institute of Mental Health (NIMH) have discovered. Mice engineered to lack this memory molecule continued to welcome strangers in spite of repeated social defeat. Their unaltered peers subjected to the same hard knocks became confirmed loners — unless the researchers treated them with antidepressants. more

 

Tall and thin or short and wide? Which holds more? It depends on if you're just looking at it or holding it.
