2.What a Gosh Heart is?

They take a pig heart, soak it in an ingredient commonly found in shampoo and wash away the cells until you’re left with a protein scaffold that is to a heart what two-by-four framing is to a house.

Then inject that ghost heart, as it’s called, with hundreds of millions of blood or bone-marrow stem cells from a person who needs a heart transplant, place it in a bioreactor–a box with artificial lungs and tubes that pump oxygen and blood into it–and wait as the ghost heart begins to mature into a new, beating human heart.

Doris Taylor, director of regenerative medicine research at the Texas Heart Institute at St. Luke’s Episcopal Hospital in Houston, has been working on this– first using rat hearts, then pig hearts and human hearts–for years.

The process is called decellularization and it is a tissue engineering technique designed to strip out the cells from a donor organ, leaving nothing but connective tissue that used to hold the cells in place.

This scaffold of connective tissue–called a “ghost organ” for its pale and almost translucent appearance–can then be reseeded with a patient’s own cells, with the goal of regenerating an organ that can be transplanted into the patient without fear of tissue rejection.

This ghost heart is ready to be injected with a transplant recipient’s stem cells so a new heart–one that won’t be rejected–can be grown.

As impressive as the Lockheed SR-71 was, it had a secret older brother (the A-12) which was even faster, lighter, and had a higher service ceiling

The first man to fly faster than the speed of sound, revived his feat on October 14 2012 in an F-15 Eagle, to celebrate the 65th anniversary of breaking the sound barrier. He was 89 years old. – Source

4. 85% of people use music to reduce their daily emotional stress.

To incorporate music into a busy life, try playing CDs in the car, or put the radio on when in the bath or shower. Take portable music with you when walking the dog, or put the stereo on instead of the TV.

Singing (or shouting) along can also be a great release of tension.  Calming music before bedtime promotes peace and relaxation and helps to induce sleep.

  • Music’s form and structure can bring order and security to disabled and distressed children. It encourages coordination and communication, so improves their quality of life.
  • Listening to music on headphones reduces stress and anxiety in hospital patients before and after surgery.
  • Music can help reduce both the sensation and distress of both chronic pain and postoperative pain.
  • Listening to music can relieve depression and increase self-esteem ratings in elderly people.
  • Making music can reduce burnout and improve mood among nursing students.
  • Music therapy significantly reduces emotional distress and boosts quality of life among adult cancer patients.
