How Does Gene Imprinting Shape Behavior and Brain Development?
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. More

Developing a Tiny, Wireless Sensor to Monitor Glaucoma Around the Clock
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. More

Discovering New Strategies to Treat Neurodegenerative Diseases
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. More

Building a Better Foundation for Structural Studies of Membrane Proteins
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. More

What Can Ants Teach Us About Aging and Behavior?
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.

The Unfolded Protein Response: A Good Target for Drug Design?
Like Lucy Ricardo and Ethel Mertz scrambling to wrap the chocolates that roll relentlessly down the candy factory’s conveyor belt, a cell’s protein-folding team can only do so much with limited resources. And an unfolded protein that slips by unfolded can spark far more trouble for an organism than a stern factory supervisor. More

A Better Wiring Guide to the Mammalian Brain
Neuroscientists working to understand how cells in the brain communicate with one another dream about one day having a precise map charting exactly how each cell connects to the next. Such a map would be a powerful tool for learning how the brain processes information and controls behavior, as well as recognizing how neuronal communication breaks down during disease. More

Speed Scanning the Genome for Neurodegenerative Disease Therapies
In neurodegenerative diseases, such as Alzheimer and Parkinson, misfolded proteins form toxic traffic jams that stop neurons from functioning normally. As the neurons malfunction and eventually die, people experience symptoms ranging from memory loss to lack of motor coordination. More
