While short telomeres do lead to health problems, long telomeres lead to health problems of their own. Armanios led, shows that the telomere story is no exception. And a paper published Thursday in the New England Journal of Medicine, with results of a study that Dr. “And the longer the better.”īut, of course, nothing in biology is so simple. Mary Armanios, professor of oncology at Johns Hopkins University School of Medicine and director of the Telomere Center at the medical school’s Sidney Kimmel Comprehensive Cancer Center. “Short telomeres were thought to be bad - people with premature aging syndromes had short telomeres - so, by analogy, long telomeres were thought to be good,” said Dr. Every time a cell divides, its telomeres get a little shorter, until finally they get so short that the cell dies.

The caps on chromosomes, called telomeres, are chains of short, repeated segments of DNA. The clocks come in the form of caps on the end of chromosomes - the long twisted strings of DNA carrying the cells’ genes.

Stop the cell clocks and you can remain youthful. And the same should go for people, who are, after all, made from cells. If you can just stop the clock, cells can live indefinitely. Cells have a molecular clock that determines how long they live. (Sept.The story, as often happens in science, sounded so appealing.

Agent: Thao Le, Sandra Dijkstra Literary. This smart, sexy contemporary should delight a wide swath of romance lovers. The delightful supporting characters, especially Adam’s colleague Holden Rodriquez and Olive’s friends Malcolm and Anh, add flavor-and readers will love seeing the villain of the story dispatched in appropriate fashion. But can their relationship hold up in the real world? With whip-smart and endearing characters, snappy prose, and a quirky take on a favorite trope, Hazelwood convincingly navigates the fraught shoals of academia. Things further evolve after Olive is harassed and belittled at a professional conference and Adam provides a supportive shoulder. But as attraction and chemistry grow, their relationship becomes more than pretense. But Olive briefly dated Anh’s current crush, Jeremy, and now Anh’s refusing to act on her feelings because of “girl code.” In an attempt to prove she’s over Jeremy and alleviate Anh’s guilt, Olive impulsively kisses famously irascible professor Adam Carlsen and convinces him to “fake-date” her.

Olive Smith, a third-year PhD student in biology at Stanford University, doubts that happily ever after exists, while her bestie, Anh, is a hopeless romantic. Hazelwood debuts with a charming, offbeat rom-com pairing a somewhat awkward doctoral candidate with a hotshot young professor.
