Scientists have long known of the potential risk from cosmic rays and other aspects of space weather, such as streams of protons from the Sun, to airline electronic systems, passengers, and crews. It has not been feasible to quantify this risk, however, as systematic data are lacking on the actual amount of rays and the charged particles and neutrons they create in Earths atmosphere that are encountered during typical flights. Researchers have now begun collecting that information, thanks to a newly developed instrument, the Low Linear-Energy-Transfer Radiation Spectrometer (LoLRS).
The need to know the precise level of cosmic and solar radiation along air routes has become more acute, as recent generations of commercial aircraft use "fly-by-wire" control systems, managed by on-board computers, which are subject to damage by high radiation levels. Future aircraft will employ even more sensitive technologies, and will therefore be more susceptible to damage.
"This substantially increases the need to improve the definition of the atmospheric radiation field as a function of location and time, and to reduce the significant uncertainties associated with present day predictions," says Epaminondas G. Stassinopoulos of NASAs Goddard Space Flight Center, lead researcher of the project. Their report is one of the first papers published in the American Geophysical Unions new journal, Space Weather.

Abnormal scarring is a serious threat resulting in non-healing chronic wounds or fibrosis. Scars form when fibroblasts, a type of cell of connective tissue, reach wounded skin and deposit plugs of extracellular matrix. Until today, the question about the exact anatomical origin of these fibroblasts has not been answered. In order to find potential ways of influencing the scarring process, the team of Dr. Yuval Rinkevich, Group Leader for Regenerative Biology at the Institute of Lung Biology and Disease at Helmholtz Zentrum München, aimed to finally find an answer. As it was already known that all scars derive from a fibroblast lineage expressing the Engrailed-1 gene - a lineage not only present in skin, but also in fascia - the researchers intentionally tried to understand whether or not fascia might be the origin of fibroblasts.

Research from a leading international expert on the health of the Great Lakes suggests that the growing intensity and scale of pollution from plastics poses serious risks to human health and will continue to have profound consequences on the ecosystem.
