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.
Study Provides More Evidence That Sleep Apnea Is Hurting Your Brain
Employing a measure rarely used in sleep apnea studies, researchers at the UCLA School of Nursing have uncovered evidence of what may be damaging the brain in people with the sleep disorder — weaker brain blood flow.
UCLA Biologists Delay the Aging Process by 'Remote Control'
UCLA biologists have identified a gene that can slow the aging process throughout the entire body when activated remotely in key organ systems. Working with fruit flies, the life scientists activated a gene called AMPK that is a key energy sensor in cells; it gets activated when cellular energy levels are low.
In Sync And in Control?
In the aftermath of the Aug. 9 shooting of an 18-year-old African American man by a white police officer in Ferguson, Missouri, much of the nation's attention has been focused on how law enforcement's use of military gear might have inflamed tensions. But what if the simple act of marching in unison — as riot police routinely do — increases the likelihood that law enforcement will use excessive force in policing protests?
In Our Digital World, Are Young People Losing the Ability to Read Emotions?
Children's social skills may be declining as they have less time for face-to-face interaction due to their increased use of digital media, according to a UCLA psychology study. UCLA scientists found that sixth-graders who went five days without even glancing at a smartphone, television or other digital screen did substantially better at reading human emotions than sixth-graders from the same school who continued to spend hours each day looking at their electronic devices.
Scientists Discover How 'Jumping Genes' Help Black Truffles Adapt to Their Environment
Black truffles, also known as Périgord truffles, grow in symbiosis with the roots of oak and hazelnut trees. In the world of haute cuisine, they are expensive and highly prized.
