NASA oceanographers agree that the recent La Nina in the eastern Pacific Ocean is not expected to have an effect on the Atlantic hurricane season this year. That is good news, because normally a La Niña tends to increase Atlantic hurricane activity and decrease Pacific Ocean hurricanes.
Although La Nina occurs in the Pacific, it affects weather in the Atlantic Ocean as well, through changes in the winds. La Niña changes the wind patterns in the upper and lower levels of the atmosphere, which make it easier for hurricanes to form in the Atlantic and harder in the eastern Pacific. In the Atlantic, the winds that would normally tear a hurricane’s circular motion apart are lessened but they increase in the eastern Pacific.
The National Oceanic and Atmospheric Administration’s (NOAA) Climate Prediction Center is the federal agency that monitors La Nina conditions such as cooler than normal sea surface temperatures, precipitation and winds. According to their latest report on April 6, 2006, sea surface temperatures were warming back to normal. That latest report stated that during the month of April, sea surface temperatures were slightly cooler than normal in the extreme eastern equatorial Pacific, and conditions returned to near average in that region.

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...
