Susan Lindquist believes that if “personalized medicine” for complex neurodegenerative disorders is to become a reality then scientists must begin developing more rigorous approaches to identifying and validating promising new therapies.
Images in biology textbooks may give the misleading impression that the cell membrane is a passive envelope that does little more than keep the cell’s internal contents in place. Howard Hughes Medical Institute researcher Douglas C. Rees prefers to think of the outer membrane of human cells as a dynamic boundary that sends and receives vital information about the state of affairs inside and outside the cell.
Ants first marched into Danny Reinberg’s world about four years ago as he began thinking about taking his lab in a new direction. Now, he cannot keep ants off his mind because they are the focal point of a newly funded HHMI Collaborative Innovation Award to study whether epigenetics influences the behavior and aging of ants.
In mammals, cells carry out their work driven by two copies of nearly every gene, one inherited from each parent. If something happens to one gene, the other is usually there to compensate. But for a small number of genes, the two copies rule does not apply. For those genes, only one parent’s copy is turned on,and the other is shut off. This regulatory process leaves little room for error because there is no gene to act as a backup if problems arise.
Nearly 70 million people worldwide have glaucoma, an insidious group of diseases that damages the optic nerve and leads to vision loss and blindness. High intraocular pressure, which damages nerve cells in the eye, is one of the biggest known contributing factors in the development of glaucoma.
