Inflating a set of cat lungs
Lungs are by most accounts mundane. Everybody has them, few give it much thought. But sequestered within darkness of the chest cavity, enveloping the fluttering heart, there’s an incredible wonder to this oddly inflatable organ.
Dissection is a destructive process. Rudely excised from membranous mooring and nourishing vessels, the deflated lungs appear little more than bloodied meat; amorphous and exposed…….until a breath of air unfurls its secret glory.
Here, a set of cat lungs is inflated with a straw. Comprised of hundreds of millions of microscopic air sacks called alveoli, mammalian lungs harbor air capacity that is difficult to believe unless seen. The color of the entire organ lightens into a soft pink, as each microscopic sac fills with air.
A debt of gratitude is owed to cyborgraptor for her assistance in creating these gifs, as well as the students that helped me film this demo.
Kids, don’t try this at home, OK?
So gross, but so cool….we can’t stop looking at this.
Maybe the reason that money doesn’t make us happy is that we’re always spending it on the wrong things, and in particular, that we’re always spending it on ourselves.
If you think money can’t buy happiness, you’re not spending it right. The implication is not, you should buy this product instead of that product and that’s the way to make yourself happier. It is, in fact, that you should stop thinking about which product to buy for yourself and try giving some of it to other people instead.
Think less about, ‘How can I spend money on myself?’ and more about, ‘If I’ve got five dollars or 15 dollars, what can I do to benefit other people?’ Because ultimately, when you do that, you’ll find that you’ll benefit yourself much more.
On this Cyber Monday, we don’t have any promo codes or delivery drones, but what we do have is pretty awesome: the super smart Harvard Business professor Michael Norton talking about how to buy happiness.
In his talk, Michael shares years of research on how money affects our happiness, revealing that buying that present for your mom might be healthier than you think.tedx)
Soda/Pop/Coke: How Americans Talk
In 2003, then Harvard professor Bert Vaux conducted the Harvard Dialect Survey, in which he interviewed tens of thousands of Americans about how they talk, and released the results here.
In 2012, graduate student Joshua Katz used the data to create a beautiful set of interactive dialect maps.
And in 2013, The Atlantic called up a lot of people, asked them some of Bert Vaux’s questions, layered them over maps inspired by Katz’s and made the video above.
In developing nations, a relatively simple footbridge can make the difference between getting an education and staying at home, between receiving health care and being sick.
Peace Corps Response Volunteer Nate Bloss has been working with Bridging the Gap Africa as a project supervisor in Kenyan communities where people and economies are affected by the ability to cross waterways safely.
Check out these pictures from the “walking world” – and see how a bridge can make all the difference.
