“When it comes to the actual issues, the two sides are not that far apart,” Professor ��ö�ٳٲ���� said, referring to G.D.L. and Deutsche Bahn.

According to Christian ��ö�ٳٲ����, a professor at the University of Applied Sciences in Berlin who studies rail transportation, that agreement has meant that Deutsche Bahn has been more willing to play hardball with the smaller G.D.L., to which most train drivers belong.

The study indicates that inaccurate protein synthesis “is a key player in aging,” ��ö�ٳٲ���� says.

To test whether slip-ups during protein synthesis propel aging in mammals, molecular biologist Erik ��ö�ٳٲ���� of the University of Zurich and colleagues genetically engineered mice to have error-prone ribosomes.

By the 18th century, German alchemist Johann Friedrich ��ö�ٳٲ���� discovered the formula, and hard-paste porcelain began being manufactured in Europe as well as in Asia.
