Scientists Use 3-D Printer To Help Create Prototype Next-Gen Pacemaker
"This video shows a rabbit heart that has been kept beating outside of the body in a nutrient and oxygen-rich solution. The new cardiac device — a thin, stretchable membrane imprinted with a spider-web-like network of sensors and electrodes — is custom-designed to fit over the heart and contract and expand with it as it beats."

If you enjoyed learning how fast you are(n’t) going in the TED-Ed video I just posted, I covered all the distance we covered in the last year, plus a whole lot more (think “gross bodily functions”) in my latest video:

A Form of Happiness: Dopamine
We have all felt the rush and experienced the feeling of happiness, and Speculative Design artist Jessica Charlesworth, along with her husband, Product Designer Tim Parsons, has made it tangible. The couples’ A Form of Happiness project has masterfully resulted in their creation of a wood and magnetic representation of the neurotransmitter responsible for releasing the chemical that fuels our desire for happiness. The effects of the organic chemical, dopamine, are likened to the euphoric feeling and pleasurable physical reaction to things such as searching through sale racks while shopping, enjoying a delicious meal, or the pleasure received from engaging in sexual activity.
A Form of Happiness, displayed as the physical model of dopamine, is part of a kit that allows user to assemble the wooden pieces into the chemical compound strand. Each part is held together by embedded neodymium magnets. The kit includes examples of the various roles that the physical piece could take on and provides a more vivid display of what occurs during moments when dopamine is released. Charlesworth and Parsons pose the question, ‘What makes you happy?’ and while the answers will vary by person, as their model and kit prove, the feeling is the same for everyone. Happiness is a simple chemical reaction we seek it throughout life; a chemical bit of magic.

Here’s a different map of the linguistic reality in Ukraine
Although Central Ukraine reports ukrainian as a native tongue, in truth a large portion of the ukrainian spoken in central ukraine consists of Surzhyk a mixed ukrainian/russian language due to centuries of russian domination.
The only way i can put it is if you imagine the Linguistic situation in Scotland, With Scots, Scottish English and RP English. Scots and RP english is related while scottish english is the one that mixes both and more predominant due to the dominant nature of english culture in scotland for centuries.
TLDR: While most maps say that ukrainian is spoken predominately in central ukraine, understand that its actually a mixed ukrainian/russian sociolect thats being classified as native ukrainian, while the western region is actually the region where the more “pure” form of ukrainian is spoken.
