Bolstered by recent laboratory findings, researchers at the University of Rochester Medical Center are embarking on a National Institutes of Health-funded clinical study to better understand the deceptive role environmental lead exposure plays in bone maturation and loss. The clinical trial is the latest in a growing body of research that is putting yet one more notch in the belt of diseases attributed to lead, and this time, researchers say, its target is older adults at risk for osteoporosis.
For decades, scientists have known that the human skeleton is a repository for lead in people who were exposed to high levels of this environmental toxin in their childhood, but thought this storage to be benign. Recently, a growing body of research is showing that the opposite is true, and that lead in bone actually sets off a bizarre chain reaction, first accelerating bone growth, and then eventually limiting it so that a high peak bone mass is not achieved. Preventing a high peak bone mass will predispose a young person to osteoporosis later in life.
Now, researchers in the Center for Musculoskeletal Research at the University of Rochester Medical Center are set to embark on the next phase of a four-year, $5 million research project funded by the National Institute of Environmental Health Sciences with a clinical study aimed at better understanding the deceptive role lead initially plays in bone development, growth and loss – and how this all might lead to earlier onset of osteoporosis in those exposed to high levels of lead as a child.

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...
