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.

UCLA Biochemists Build Largest Synthetic Molecular 'Cage' Ever
UCLA biochemists have created the largest-ever protein that self-assembles into a molecular "cage." The research could lead to synthetic vaccines that protect people from the flu, HIV and other diseases. At a size hundreds of times smaller than a human cell, it also could lead to new methods of delivering pharmaceuticals inside of cells, or to the creation of new nanoscale materials.

Plants Have Little Wiggle Room to Survive Drought, UCLA Life Scientists Report
Plants all over the world are more sensitive to drought than many experts realized, according to a new study by scientists at UCLA and China's Xishuangbanna Tropical Botanical Garden. The research will improve predictions of which plant species will survive the increasingly intense droughts associated with global climate change. The research is reported online by Ecology Letters, the most prestigious journal in the field of ecology, and will be published in an upcoming print edition.

UCLA Astronomers Solve Puzzle About Bizarre Object at the Center of Our Galaxy
For years, astronomers have been puzzled by a bizarre object in the center of the Milky Way that was believed to be a hydrogen gas cloud headed toward our galaxy's enormous black hole. Having studied it during its closest approach to the black hole this summer, UCLA astronomers believe that they have solved the riddle of the object widely known as G2.
