Through an innovative catheterization procedure, a pediatric cardiologist at Texas Childrens Heart Center in Houston repaired a severe liver condition in a 14-year-old male. The doctor used a catheter and septal occluder device that is generally used to close holes in childrens hearts. Similar procedures have been reported only six times in medical literature. But this is the first time the procedure has been performed with this particular device.
"Sammy was born with a hole in his liver about the size of a garden hose that has caused him complicated health problems," said Dr. Henri Justino, an interventional cardiologist at Texas Childrens Heart Center and an assistant professor of pediatrics at Baylor College of Medicine. "Since we successfully perform a wide variety of interventional cardiac procedures in the catheterization lab every day, we consulted with colleagues in the Liver Center, and decided to apply the same procedure in Sammys case," said Justino.
Sammy Drake, a resident of West Texas, was born with a rare liver problem known as patent ductus venosus (PDV). The ductus venosus, a large vein that crosses through the liver and empties near the heart, is normally present before birth and plays an important role in the development of the fetus. After birth, however, the PDV is no longer needed and usually closes on its own. Closure of this vein allows blood returning from the intestines to go to the liver, an essential step needed to filter certain nutrients and toxins in foods.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
