Alzheimer's disease has proven to be a difficult enemy to defeat. After all, aging is the No. 1 risk factor for the disorder, and there's no stopping that. Most researchers believe the disease is caused by one of two proteins, one called tau, the other beta-amyloid. As we age, most scientists say, these proteins either disrupt signaling between neurons or simply kill them. Now, a new UCLA study suggests a third possible cause: iron accumulation.
85 College Students Tried to Draw the Apple Logo from Memory. 84 Failed.
"You can observe a lot just by watching." - Yogi Berra Could you draw the ubiquitous Apple computer logo from memory? Probably not, as it turns out.
Researchers Help Create 'Gold Standard' Method for Measuring an Early Sign of Alzheimer's
After six years of painstaking research, a UCLA-led team has validated the first standardized protocol for measuring one of the earliest signs of Alzheimer's disease -- the atrophy of the part of the brain known as the hippocampus.
UCLA Statistician Helps Resolve Dispute About How Gene Expression Is Controlled
The differences between different tissues, such as brain and muscle, and between healthy and unhealthy human cells are largely defined by changes in the abundance of proteins in the cells. Transcription -- the process that governs the flow of genetic information from DNA to RNA -- was long believed to play the dominant role in determining the quantity of proteins in a cell. But over the past decade, many studies have claimed that in animals, differences in the rate at which RNA is
Sense of Smell May Reveal Weight Bias
Could our reaction to an image of an overweight or obese person affect how we perceive odor? A trio of researchers, including two from UCLA, says yes.
Insuring Undocumented Residents Could Help Solve Multiple US Health Care Challenges
Latinos are the largest ethnic minority group in the United States, and it's expected that by 2050 they will comprise almost 30 percent of the U.S. population. Yet they are also the most underserved by health care and health insurance providers.
UCLA Study Shows Feasibility of Blood-based Test for Diagnosing Alzheimer's Disease
UCLA researchers have provided the first evidence that a simple blood test could be developed to confirm the presence of beta amyloid proteins in the brain, which is a hallmark of Alzheimer's disease.
Researchers Identify Process for Improving Durability of Glass
Researchers at the UCLA Henry Samueli School of Engineering and Applied Science and the Université Pierre et Marie Curie in Paris have identified a method for manufacturing longer-lasting and stronger forms of glass. The research could lead to more durable display screens, fiber optic cables, windows and other materials, including cement.
People with Anorexia And Body Dysmorphic Disorder Have Similar Brain Anomalies
People with anorexia nervosa and with body dysmorphic disorder have similar abnormalities in their brains that affect their ability to process visual information, a new UCLA study reveals. People with anorexia have such an intense fear of gaining weight that they starve themselves even when they are dangerously thin. Body dysmorphic disorder is a psychiatric condition characterized by an obsessive preoccupation with a perceived flaw in physical appearance.
