For several years, crippling leg pain has prevented Joan Erickson from walking more than a block. If she paused to rest, she could walk a little more, but not enough to continue playing golf, her favorite pastime.
An ultrasound and CT scan early this year showed that an artery in Erickson’s thigh was almost completely blocked, confirming that her troubles were caused by peripheral arterial disease, or PAD - a condition in which arteries to the arms, legs or internal organs are hardened and narrowed or obstructed.
This week at Stanford University Medical Center, Erickson became the first patient in the United States to receive a new treatment for PAD as part of a clinical trial. On March 21, Stanford researchers implanted a drug-coated, flexible, metal-mesh tube called a drug-eluting stent into the superficial femoral artery in Erickson’s thigh. Researchers hope the drug coating will make it more likely to prevent the blockage from recurring, as compared with uncoated stents, which fail to do so in about one-quarter of the cases.

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...
