Repairing Damaged Heart Tissue
The secret to "mending broken hearts" has been discovered by scientists examining ways of repairing damaged tissue after heart attacks by using proteins similar to insulin.
What's the Latest Development?
"Injecting proteins similar to insulin directly into the heart can cause damaged cells to repair themselves and begin regenerating again, researchers said. Tests on pigs showed that the dormant cells could begin regrowth following a 'regenerative medicine' treatment using certain growth factors—naturally occurring proteins which cells use to communicate with their environment. Experts from Liverpool John Moores University said the four-year study presented a 'significantly different' therapy to those currently being developed by scientists."
What's the Big Idea?
The new findings, produced with teams from Italy and Spain, could lead to simpler and more affordable treatments for heart attacks. "Dr Bernardo Nadal-Ginard, Director of LJMU Stem Cell & Regenerative Biology Unit, said approaches currently being pursued in clinical trials were 'time consuming' and 'expensive'. ... "In contrast, this new approach by LJMU could ultimately lead to a clinical myocardial regenerative therapy which is effective, simple, affordable, readily and widely available and easy to apply and compatible with the current clinical standard of cardiac care."
Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.
- There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
- CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
- Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
- Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.
Protected animals are feared to be headed for the black market.
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
