UCLA Study Suggests Iron Is at Core of Alzheimer's Disease

Published: August 20, 2013.
Released by University of California - Los Angeles  

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 Researchers Identify a Potentially Effective Treatment for Methamphetamine Addiction
A new study by UCLA researchers has found that Naltrexone, a drug used to treat alcoholism, may also be a promising treatment for addiction to methamphetamine. "The results were about as good as you could hope for," said Lara Ray, a UCLA associate professor of psychology, director of the UCLA Addictions Laboratory and lead author of the new study.

Which Is Most Valuable: Gold, Cocaine Or Rhino Horn?
Many of the world's largest herbivores -- including several species of elephants, rhinoceroses, hippopotamuses and gorillas -- are in danger of becoming extinct. And if current trends continue, the loss of these animals would have drastic implications not only for the species themselves, but also for other animals and the environments and ecosystems in which they live, according to a new report by an international team of scientists.

Photosynthesis Has Unique Isotopic Signature, UCLA Researchers Report
Photosynthesis leaves behind a unique calling card in the form of a chemical signature that is spelled out with stable oxygen isotopes, UCLA geochemists reported April 24 in the journal Science. The findings suggest that similar isotopic signatures could exist for many biological processes, including some that are difficult to observe with current tools.

Stop Blaming the Moon, Says UCLA Scientist
"It must be a full moon" is a common refrain when things appear more hectic than usual. The moon is even blamed when things get crazy at hospital emergency rooms or birth wards. "Some nurses ascribe the apparent chaos to the moon, but dozens of studies show that the belief is unfounded," said Jean-Luc Margot, a UCLA professor of planetary astronomy.
