Bad Weather Increases Risk Eight-Fold
Post-crash fires, darkness or bad weather greatly decrease the likelihood of surviving an emergency medical service (EMS) helicopter crash, according to a study by researchers from the Johns Hopkins Bloomberg School of Public Health’s Center for Injury Research and Policy and Johns Hopkins School of Medicine. Improving crashworthiness of helicopters and reducing trips during hazardous conditions can decrease EMS helicopter fatality rates. The study was recently published online by Annals of Emergency Medicine.
“Crashes of EMS helicopters have increased in recent years, raising concern for patients, as well as pilots, paramedics and flight nurses,” said Susan P. Baker, MPH, a professor in the Bloomberg School of Public Health’s Department of Health Policy and Management and Center for Injury Research and Policy. “Our study found that darkness more than triples the risk of fatalities when EMS helicopters crash and that bad weather increases the risk eight-fold. Helicopter EMS programs should recognize these risky conditions and transport patients by air only when the benefit clearly exceeds the risk of the flight.”

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...
