A Diamond Age of Microelectronics at Geek Bar Chicago’s SCIENCE! Tuesday
In modern electronics, speed, durability, and the ability to withstand heat are important properties. Diamonds, when used as a semiconductor, possess not only these characteristics, but have material properties such ultra-hardness, complete transparency to visible light, ultra-high thermal conductivity, ultrafast power and frequency handling and switching.
From “Memento” to “The Eternal Sunshine of the Spotless Mind,” amnesia is a common trope in movies—a powerful launching point to explore issues such as identity and emotion. This year’s Festival includes three films, “Embers,” “Open Tables,” and “Other Madnesses,” which portray characters with faulty memories. Continue reading “Refresh My Memory”
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.
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.

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.
