Researchers call for routine mouse allergy testing for inner-city children with asthma
The amount of mouse allergen found in the air in many inner-city homes could be high enough to trigger asthma symptoms in the children who live there, say researchers at the Johns Hopkins Children’s Center. Their study, published in the February issue of the Journal of Allergy and Clinical Immunology, found more than a quarter of inner-city homes sampled had airborne allergen levels already known to aggravate asthma symptoms in animal research lab workers with mouse allergy.
"Children living in inner-city homes are continuously exposed to the allergy-causing substance found in mouse urine that is circulating in the air," says Elizabeth Matsui, M.D., a pediatric allergist at the Johns Hopkins Children’s Center and lead author of the study. "This exposure increases their risk for developing allergic sensitivity to mice, just as it does for laboratory workers who constantly work with rodents."

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...
