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.
Three-drug Combinations Could Help Counter Antibiotic Resistance, UCLA Biologists Report
Each year, approximately 700,000 people die from drug-resistant bacterial infections. A study by UCLA life scientists could be a major step toward combating drug-resistant infections. The research, reported in the journal Royal Society Interface, found that combinations of three different antibiotics can often overcome bacteria's resistance to antibiotics, even when none of the three antibiotics on their own -- or even two of the three together -- is effective.
More Evidence That Male And Female Brains Are Wired Differently
While measuring brain activity with magnetic resonance imaging during blood pressure trials, UCLA researchers found that men and women had opposite responses in the right front of the insular cortex, a part of the brain integral to the experience of emotions, blood pressure control and self-awareness.
Sierra Nevada Snowpack Not Likely to Recover from Drought Until 2019
Even with this winter's strong El Niño, the Sierra Nevada snowpack will likely take until 2019 to return to pre-drought levels, according to a new analysis led by UCLA hydrology researchers.
Impaired Decision-making May Contribute to Motor Symptoms in Parkinson's Disease
UCLA researchers have discovered that people with Parkinson's disease have a form of impaired decision-making that may be a major contributor to the movement problems that characterize the disease. The finding suggests that the neurological factors underlying Parkinson's, which currently affects nearly 1 million people in the United States, may be more complex than commonly believed. The study also could pave the way for strategies to detect Parkinson's earlier in its course.
Scientists Discover Biomarkers That Could Give Cancer Patients Better Survival Estimatesl
People with cancer are often told by their doctors approximately how long they have to live, and how well they will respond to treatments, but what if there were a way to improve the accuracy of doctors' predictions?
Some Asian-Americans Are Predisposed to Want More Carbs And Fast Food
Rice anyone? How about a bowl of ramen noodles? Researchers have found that some Asian-Americans are more likely to hunger for carbohydrates and unhealthy foods than other Asian-Americans -- and the reason appears to be genetic.
Teenage Brain on Social Media
The same brain circuits that are activated by eating chocolate and winning money are activated when teenagers see large numbers of "likes" on their own photos or the photos of peers in a social network, according to a first-of-its-kind UCLA study that scanned teens' brains while using social media.
A Planet 1,200 Light-years Away Is a Good Prospect for a Habitable World
A distant planet known as Kepler-62f could be habitable, a team of astronomers reports.
