Bad news. A major vulnerability, known as “Heartbleed,” has been disclosed for the technology that powers encryption across the majority of the internet. That includes Tumblr.
We have no evidence of any breach and, like most networks, our team took immediate action to fix the issue.
With some straightforward logic, one theorist has shown that macroscopic quantum objects cannot exist if P≠NP, which sud…
Heart surgery is an extremely difficult procedure. Even more so when the tiny anatomy of a small child is involved. When 14-month old Roland Lian Cung Bawi’s heart was failing him, his surgeon Erle Austin knew that he had to prepare meticulously for an intricate operation. Initially he consulted other surgeons, but this yielded conflicting advice. So Austin turned to 3D printing for help.
Using the facilities at the University of Louisville’s engineering school, Austin and his medical team produced a three dimensional model of little Ronald’s heart. Pediatric operations are difficult because the interior structures of a child’s organs are small and hard to see clearly. This model allowed the surgical team to come up with a precise plan to limit the amount of exploratory incisions, reduce operating time and prevent the need for follow-up operations.

What happens when you ask a synthetic biologist to mix you up a cocktail? You learn how to isolate strawberry DNA. (The sticky stuff on the toothpick up there.)
Wanna know how to make a strawberry DNA cocktail yourself? We’ve got you covered.
In this animated how-to video, TED Fellow / synthetic biologist Oliver Medvedik shows you how to use pineapple juice and Bacardi 151 to isolate strawberry DNA for a very nerdy adult beverage. Watch the whole thing here»
A biology lesson and a cocktail recipe in one? You’re welcome. Drink responsibly and read more about the video here.
