Best Day of My Life in Russian w/#Cardiology!
We really do have heartstrings. They’re called the chordae tendinae. Our hearts have four chambers. Two at the top and two the bottom. The two top chambers, the atria, collect blood. The right atrium gets oxygen-poor blood from the from the veins which is then sucked through three-leaf valve into the right ventricle then pumped into the lungs. The left atrium receives oxygen-rich blood from the lungs that blood gets sucked through a two-leaf valve into the left ventricle which pumps it, all rich and oxygenated, into the aorta and throughout the body. Helping to prevent the blood from regurgitating from either ventricle back into either atria are the chordae tendinae, our heart strings. As suspension lines help a parachute stay properly shaped to mechanically resist the downward pull of gravity the chordae tendinae help heart valves resist the upward pressure of the ventricles. When we are stimulated, our hearts beat faster and harder tugging ever more on our heartstrings.
Evolution at the South Pole
Chicago Council on Science and Technology and the Field Museum are proud to present “Evolution at the South Pole” as part of the Field’s Evolution at Revolution series.
Hosted by Emily Graslie of the BrainScoop, the series serves as an exploration of evolution with Field scientists.
Mapping the Brain: Chicago Researchers Connect the Network

Originally published at: http://news.medill.northwestern.edu/chicago/chicago-researchers-connect-the-network-mapping-the-brain/
A comprehensive map of the human brain is in the works with the promise of eventually creating new neurological treatments and diagnoses for mental illnesses, Alzheimer’s disease and other disorders.
The BRAIN Initiative researchers at the University of Chicago, Argonne National Laboratory and in labs around the country are in the beginning stages of mapping, starting with mice and moving up the scale to humans.

C2ST Speakeasy: “Dirty Secrets: managing soil systems for a sustainable future” with Dr. Bala Chaudhary
The United Nations has recognized 2015 as the International Year of Soils, yet how many of us appreciate the fact that we can’t eat, breathe, drink, or maintain healthy communities without good soil. Let’s talk dirty and explore the diverse and complex world of soil as well as how local scientists manage soil systems to maintain ecosystem services.

C2ST Speakeasy with Dr. Bala Chaudhary
Dirty Secrets: Managing Soil Systems for a Sustainable Future at Geek Bar Chicago’s SCIENCE! Tuesday
We can’t eat, breathe, drink, or maintain healthy communities without good soil.
Dr. Bala Chaudhary, faculty in the Institute of Environmental Sustainability at Loyola University Chicago, will talk dirty and take us through the diverse and complex world of soil. The United Nations has recognized 2015 as the International Year of Soils. Let’s talk dirty and explore the diverse and complex world of soil as well as how local scientists manage soil systems to maintain ecosystem services. Come learn how Chicago scientists are incorporating soil organisms into green roofs to manage storm water, cool neighborhoods, and reduce energy costs. Also, learn what you can do to improve soil health in your own backyard and beyond.
