WASHINGTON — ”Difficult Access Team” attaches ropes to the top of the Washington Monument, on the National Mall, in Washington, from which four people will rappel down the sides to survey the extent of damage sustained to the monument from the Aug. 23 earthquake. Congress allocated $7.5 million late in 2011 to repair the damage to the monument caused by the Aug. 23, 2011, 5.8-magnitude earthquake.

Five artists from Team Sandtastic created this massive 525-ton sand sculpture of the GOP candidates at Myrtle Beach, South Carolina. The Mount Rushmore-like artwork features the faces of Jon Hunstman, Mitt Romney, Newt Gingrich, Rick Perry, Rick Santorum and Ron Paul. Built from locally mined sand, the sculpture took six days to build (which included one rain out) and, impressively, stands 80 feet wide by 17 feet tall.

Here’s what I learned from a website titled, Human Heart, from the Franklin Institute.
An Austrian scientist named Karl Landsteiner was awarded the Nobel Prize for classifying blood according to differences he saw in the red blood cells. He found two different chemical molecules on the surface of red blood cells and called them A and B. Folks with either of these molecules have A or B type blood respectively and people with both chemical molecules are AB blood type. Those of us with neither of the chemical molecules on our red blood cells have O type blood. Which is most common? Which is most rare? Check out the Human Heart site.
WHICH BLOOD TYPE ARE YOU?

The Silk Road was not actually a road. It was not paved. It was not even a single route. The Silk Road was a name given to any route that led across China to Rome. It was a 4000-mile trip. At one end was China. At the other end was Rome. Each had something the other wanted. Rome had gold and silver and precious gems. China had silk and spices and ivory. Ideas also traveled along the Silk Road, ideas that affected everyone.The Romans were not surprised to hear of another great civilization hidden over the mountains. They had been looking for “the Silk People” for a long time. The Romans discovered pieces of silk from some of the people they conquered. Silk quickly became popular in Rome. But it was scarce. The Romans wanted more silk. But they did not know who was making this wonderful material. The Romans tried to find the traders as they came into the towns and villages. But the traders hid from the Roman soldiers. They knew they had nothing to tell them. They did not know who was making the silk. They only traded for the silk. They traveled a short way along the silk road and traded with the people they found.
