Let's have lunch! -- teachers eating with their students provides nutrition education opportunities

Swedish researchers found three types of teachers who interacted with children during meals: sociable, educating, and evasive. To realize the potential of nutrition education, teachers must be aware of their actions. The study provides a useful tool for clarifying best practices for teacher-student interactions during mealtimes.

Minimally invasive stents show some advantage over bypass in opening blocked leg arteries

A small study found that patients who received minimally invasive stents had a 31% risk of needing another procedure within 24 months, compared to 54% for those who received bypass surgery. The researchers hope to confirm these findings with further study and develop guidelines for determining when a stent is likely to be best.

Altering organic molecules' interaction with light

Researchers at MIT have discovered a new platform that enables dramatic manipulation of organic molecules' emission by suspending them on top of a carefully designed planar slab with a periodic array of holes. This platform has important implications for applications such as bio-imaging, bio-molecular detection and the development of o...

The dark side of entrepreneurship

Researchers found that entrepreneurs exhibit higher levels of rule-breaking behavior during adolescence, such as cheating and truancy. However, this behavior tends to dissipate by adulthood, with most entrepreneurs showing no significant difference in anti-social tendencies compared to non-entrepreneurs.
