“We have been observing the sun during the space age for only 50 years and we do not fully understand its behavior, especially the extremes of its behavior. In 2006 there was an eruption of solar radiation 100 times more intense than expected that temporarily silenced many GPS receivers over the sun-lit Earth. What is the ultimate limit of such eruptions of solar energy? Is it 1,000 times more intense, 10,000 times more intense? We just don’t know.
“For the past 50 or 60 years, the sun has been quite predictable. In recent years, it has become less predictable, which calls into question our understanding of how the sun operates and our ability to predict is impact on technology.
“However, we do know that our increasingly more efficient infrastructure is also less robust and more vulnerable. Every time its efficiency is improved and money is saved, the chances for a catastrophic failure are increased and this includes failures produced by space weather.
“For many GPS applications, business plans make demands that the designers of GPS never envisioned – nor does the U.S government guarantee. Space weather – such as the upcoming period of increased solar activity – will challenge these business plans and test the vulnerabilities of our communications and navigation infrastructure.”

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...
