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.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
