A new study to be published in tomorrows New England Journal of Medicine shows that United States investment in tuberculosis (TB) treatment abroad saves lives and money at home. Most cases of TB in the US and Canada occur among immigrants, refugees, visitors, and other migrants from countries where this disease remains common.
An international team led by McGill University Health Centre researchers Dr. Dick Menzies, Dr. Kevin Schwartzman, and Ms. Olivia Oxlade predicts that better TB control in high incidence countries would reduce transmission there, and result in fewer migrants developing TB disease in the US, fewer TB-related deaths in the US, and financial savings in the US. This research was funded by the Rockefeller Foundation.
The current US approach to TB screening of immigrants and refugees depends on chest X-rays obtained before or on arrival, with treatment of tuberculosis when detected. The research team predicted the number of TB cases, related deaths, and costs over the next 20 years that would occur as a result of this strategy in migrants arriving in the US from Mexico, the Dominican Republic, and Haiti. They compared these results with expected outcomes if TB control programs in these three countries received US funding to improve diagnosis and treatment in the home country--to the standard recommended by the World Health Organization.

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...
