Bio-Inspired Climbing Robots at Geek Bar Chicago’s SCIENCE! Tuesday

Like robots? How about robots inspired by nature, robots that can climb surfaces, perch on rails, and do so seemingly undetected? In the robotics community, there is considerable interest in mobile robots that can climb and perch on a wide variety of building surfaces. These robots can be useful for sensor placement and long-term surveillance. The key is the design of controllable attachment mechanisms that can easily turn the adhesion on and off, to allow the robot to move across a surface. There have been numerous solutions for climbing specific wall types (e.g. electromagnets for ferromagnetic walls); however, these robots have limited usefulness in the real world as they tend to be too specialized.

The Neuroscience of Addiction at Geek Bar Chicago’s SCIENCE! Tuesday

The use and abuse of substances that change the way we feel is a human tendency documented throughout history. This tendency wasoften explained from viewpoints of spirituality, will-power and morality. Modern science is reshaping this dialogue, bringing the neurobiology of emotion, judgment and reward to this conversation. Dr. T. Celeste Napier will show the contributions that science has made to this topic, discussing such questions as why do people take drugs in the first place? What is the switch in the brain that changes occasional drug use into addiction? Is there a genetic vulnerability to become addicted? What other factors (stress, environment, teen brain) can promote addiction? To what extent is addiction a disease of the brain?
