Unfortunately, it was a different problem on each occasion and astronauts were unable to isolate exactly what was going wrong. A spacewalk is scheduled for June 8, when the astronauts could try replacing a computer mounted on the arm. If that doesn't do the trick, NASA might have to schedule a special repair mission, sending up a team of spacewalkers to replace the arm's entire shoulder joint. That would push back construction by at least two months. American researchers say you can predict how aggressive a bull will be by looking at the pattern of his hair.
Most bulls have a swirl of hair known as a whorl somewhere on their faces.
Bulls who have the whorl on their foreheads, or who don't have a whorl at all are significantly more likely to be aggressive. As a bull grows, the pattern of the whorl is laid down by cells that also form the nervous system. That may be the reason for the apparent correlation between the location of a whorl and what's going on in the animal's brain. Republished with permission. All Rights Reserved.
