Why do informal markets resist formalizing, even when the gains of doing so outweigh its costs in the long run? While a number of responses to this questio
We have used analysis of 3D flight trajectories to address the long-standing question of why insects aggregate around light at night and seem unable to leave. We found that at short ranges most insects do not fly directly to a light source, but orthogonally to it, leading to orbiting, stall...

From the time we are babies,we watch and mimicothers.We learn vicariously from the ways that others are rewarded and punished, and we adapt our behaviors so we can maximize rewards and avoid punishment. Hence our social contexts matter, and approval and disapproval from others shapes our futur...
parasitologists like Kinsella are sometimes the only expert on a specific group. When these scientists die, their intricate understanding of how to classify and connect species goes with them. “When I’m gone, I don’t know if there’s anybody left that can do what I do,”...
Instead of generating sounds by moving within the soil as moles do, these animals apparently stomp on the surface, generating vibrations that may mimic those from rain. These vibrations "can cause earthworms to come to the surface and fall prey to the predator," Butt said. A tradition known ...
Here’s why I’m excited about the potential of robotics technology. Is it harder for machines to mimic the way humans move or the way humans think? If you had asked me this question a decade ago, my answer would have been “think.” So much of how the brain works is still a myste...
As a business coach with years of experience advising high-growth companies, I’ve seen CEOs and founders tempted to imitate others’ success, only to become frustrated when it doesn’t work. Strategies are context-dependent and tailored to specific market dynamics, cultures, and customer needs....
The getter/setter idiom is a commonplace feature in many Java programs. Most of these accessor methods, however, are unnecessary and can severely impact your systems' maintainability. Using accessors violates the basic object-oriented (OO) principle of e
