By Kelly Rae Chi Screening Whole How to reel in high-throughput results using worms and fish. In the past few years, improvements in imaging and automation techniques have made it easy for researchers to see hundreds of plates of cells partake in every activity from differentiation to apoptosis. But in living and breathing animals, we’re only just beginning to realize the potential of large-scale screens. “To take a whole animal and
Amygdala's Inner Workings
Harvey Black | Oct 1, 2001 | 6 min read
The amygdala, an almond-sized and -shaped brain structure, has long been linked with a person's mental and emotional state. But thanks to scientific advances, researchers have recently grasped how important this 1-inch-long structure really is. Associated with a range of mental conditions from normalcy to depression to even autism, the amygdala has become the focal point of numerous research projects. Derived from the Greek for almond, the amygdala sits in the brain's medial temporal lobe, a fe
Brainstorms Abound At NIH's Neurological And Stroke Institute

Research in the neurosciences is in the midst of a particularly exciting period of discovery, says Zach Hall, director of the National Institute of Neurological Disorders and Stroke (NINDS), as scientists continue to learn more about the basic biology of such disorders as stroke, epilepsy, and degenerative conditions like Parkinson's, Alzheimer's, and Huntington's diseases. Hall's institute has supported and participated in many of these landmark studies. Now the field stands poised on the brin

WHAT FOLLOWS TAMOXIFEN? Warnings accompanied recent announcements from the University of Pittsburgh-based National Surgical Adjuvant Breast and Bowel Project and the National Cancer Institute in Bethesda, Md., that tamoxifen achieved a 45 percent reduction in the incidence of breast cancer compared to women who took a placebo in the Breast Cancer Prevention Trial. The 25-year-old drug still carries the risk of serious side effects for women over 50, officials said. But the overall results were
A Weighty Matter: Neuropeptides Involved In Appetite And Energy Homeostasis
Deborah Wilkinson | Sep 12, 1999 | 10+ min read
Date: September 13, 1999Table of Neurochemical Manufacturers The hypothalamus has long been known as a control center for feeding and weight control behaviors. Complex regulatory feedback loops enable this portion of the brain to determine satiety and metabolic activity. Not surprisingly, the control mechanisms are complex and involve different biochemical pathways.1,2,3 Image courtesy of Jeffrey M.
