Study links obesity to increased risk of developing postoperative infection following colon surgery

A study published in Archives of Surgery found that obese patients are at a significantly higher risk of developing surgical site infections after colectomy. The study also showed that these infections result in increased costs, lengthier hospital stays, and a higher rate of hospital readmissions. As pay-for-performance models penalize...

The incomplete art of brand imagery

A study by Henrik Hagtvedt found that incomplete typeface logos can create interest and spark innovation perception, but also lead to unclear communication and untrustworthiness. The results suggest that firms should avoid such logos when trust is critical, but may be effective for promotion-focused consumers.

What's in a simple line drawing? Quite a lot, our brains say

A new study using brain scans reveals that simple line drawings can activate similar patterns of brain activity as color photographs when viewing natural scenes. This suggests that the brain uses abstract representations to categorize scenes and doesn't need features like texture and color to tell a beach from a street scene.
