Triple Helix: Designing a New Molecule of Life: Scientific American. For all the magnificent diversity of life on this planet, ranging from tiny bacteria to majestic blue whales, from sunshine-harvesting plants to mineral-digesting endoliths miles underground, only one kind of “life as we know it” exists. All these organisms are based on nucleic acids—DNA and RNA—and proteins, working together more or less as described by the so-called central dogma of molecular biology: DNA stores information that is transcribed into RNA, which then serves as a template for producing a protein. The proteins, in turn, serve as important structural elements in tissues and, as enzymes, are the cell’s workhorses. Yet scientists dream of synthesizing life that is utterly alien to this world—both to better understand the minimum components required for life (as part of the quest to uncover the essence of life and how life originated on earth) and, frankly, to see if they can do it.

Communicating at an unknown rate. 49 Fascinating YouTube Videos to Learn About the Human Body. As any doctor, nurse practitioner or other health care professional knows, the body is an interesting system. In many ways, it’s like a machine, with many complex parts. There is a lot to learn about the body and how it works, as well as how its different systems interact to create a larger system. Here are 49 interesting YouTube videos that can help you learn about the human body: Brain Your brain directs the rest of the body’s functions.

Neuroscience. Artifiical Heart. For decades, the quest for the perfect artificial heart has been wrought with many technical challenges that have made it difficult to design a device that mimics the living, pumping organ. But Drs. Billy Cohn and Bud Frazier of the Texas Heart Institute say that trying to copy the function of the living organ has been part of the problem. They’ve developed a non-beating, non-pumping machine that delivers blood through the body with the use of simple whirling rotors. Although such a device would leave a person without a pulse, it could work better than pumping devices, thereby prolonging the patient’s life while also reducing the chance of infection or other complications. NEWS: Boy, 15, Gets a Robotic Heart Inside the institute’s animal research laboratory resides an 8-month-old calf.
The team has removed the calf’s heart and replaced it with two centrifugal pumps that ‘spin’ blood throughout the animal’s body. CURIOSITY.COM: 10 Reasons Why Laughing Is Good for You [Via NPR] Jellyfish. Genetic green light. By Fiona Macrae Updated: 07:27 GMT, 16 June 2011 Scientists have altered the ‘code of life’ in a breakthrough that could lead to cures for hundreds of devastating diseases. The discovery, hailed as ‘the new miracle of modern medicine’ could lead to ways of ending the symptoms and the pain caused by up to a third of genetic conditions. These include cystic fibrosis, Britain’s most common life-threatening inherited condition, haemophilia and Duchenne muscular dystrophy, an incurable condition that cripples 100 babies born in the UK every year. The excitement centres around mRNA - the 'cousin' of DNA that contains the genetic sequence used to make the proteins needed to keep our bodies working properly Various tumours could also be in its grasp, the journal Nature reports.
