The most dangerous phrase in the language is, “we’ve always done it this way.”
"Come on, let’s mix it up!" The heart surgeon says.
"B-but we’ve always done it this way!" The other replies, "this is how you replace a heart valve."
"That’s the most dangerous phrase in the human language!" The first surgeon replies haughtily as he inputs a fruit loop into the patient’s heart. "This will be his valve. He will be a fruit loop in a world of Cheerios."

This is serious business, because this is a large part of how sexism, racism, homophobia, rape culture, ethnocentrism, etc. continue to happen.
Jell-O-like Substance Attracts, Kills Cancer Cells
Chasing cancer cells with chemotherapy drugs can save lives, but there’s no guarantee that the treatment will kill every run-away cancer cell in the body.
What if, instead of hunting those metastatic cells, a treatment could lure them out of hiding — every last one of them — and eliminate them in one swift blow? Yong Wang, associate professor of bioengineering at Penn State, has created such a therapy — a tissue-like biomaterial that attracts cancer cells, like bits of metal to a magnet, and entraps them.

JOINTS IN MOTION
As said by IFL science
Cameron Drake of San Francisco has created a collection of magnificent images showing joints in motion. He was aided by orthopedic physician Dr. Noah Weiss and the finished product is completely amazing. If you’d like to know more about the project, please check out Drake’s blog.
Fiery Looping Rain on the Sun [Full HQ video]
Eruptive events on the sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material called a coronal mass ejection (CME), and some with complex moving structures in association with changes in magnetic field lines that loop up into the sun’s atmosphere, the corona.
On July 19, 2012, an eruption occurred on the sun that produced all three. A moderately powerful solar flare exploded on the sun’s lower right hand limb, sending out light and radiation. Next came a CME, which shot off to the right out into space. And then, the sun treated viewers to one of its dazzling magnetic displays — a phenomenon known as coronal rain.
What a superbly innovative thermoelectric powered torch!
15 Year Old Canadian Invents Flashlight Powered by Your Hand
Another reason to be proud to be Canadian today!
Portable light sources have been one of the most evolving inventions in history — from the primative torches and oil lamps of yesteryear, to today’s battery-powered flashlights and headlamps. But through it all, most of these illuminating tools have required an outside energy source that would deplete when needed the most.
But now, thanks to one particularly enlightened 15-year-old girl from Canada, your next flashlight just might be powered by the heat from your hand. Introducing, the thermoelectric ‘Hollow Flashlight’ — submitted for the Google Science Fair.
