Fatal, electrical chaos can develop in the hearts of otherwise healthy people who produce a defective accessory protein called ankyrin-B, reports W. Jonathan Lederer of the University of Maryland Biotechnology Institute (UMBI) and collaborators, in the February 6 issue of the scientific journal Nature.
By discovering the molecular and cellular causes of the electrical chaos-known as Long QT Syndrome Type 4, or LQT4-Lederer and collaborators open the door to possible therapies and diagnostics for this and related heart diseases. The work also provides a clue to how important, specific proteins are organized within heart cells.
Several years ago, clinical researchers in France, headed by Denis Escande, discovered an inheritance pattern in members of a family who had been dying suddenly and unexpectedly in the prime of life. Lederers team at UMBI and the University of Maryland at Baltimore and researchers at Duke University, headed by Vann Bennett, collaborated with the French by applying state-of-the-art heart physiology tools to mouse heart cells in order to find the cause of the sudden deaths.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
