Dr. Arnold, 62, an American professor of chemical engineering, bioengineering and biochemistry at the California Institute of Technology in Pasadena, earned the award for her work with the
She shared this year’s chemistry Nobel — worth close to $1 million — with George P. Smith, 77, and Gregory P. Winter, 67. Dr. Arnold received half of the prize, and Dr. Smith and Dr. Winter split the other half.
Dr. Arnold won for her work conducting the directed evolution of enzymes, proteins that catalyze chemical reactions. She first pioneered the bioengineering method, which works similar to the way dog breeders mate specific dogs to bring out desired traits, in the early 1990s, and has refined it since then.

I know that the title is kind of redundant when mentioning sperm and men in the same line. I wrote it like that to make sure Google crawls it the right way. You know, we humans still way smarter than the Google robots -now, you are supposed to smile, or laugh 🙂
Hiding in plain sight.
Sperm has been having a tough time lately. The concentration per ejaculate is getting lower, scientists have created an artificial version that could one day replace it, and to make matters worse, common household products might affect the quality of the little guys.
“Abnormalities in the formation and function of the atypical centriole may be the root of infertility of unknown cause in couples who have no treatment options available to them,” Tomer Avidor-Reiss, from Toledo’s Department of Biological Sciences, said in a press release.
“It also may have a role in early pregnancy loss and embryo development defects.”
You need two centrioles to make the working centrosome, and until now it was thought that the sperm provided one centriole to the egg, and then duplicated itself.
