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

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.

Don't Use Body Mass Index to Determine Whether People Are Healthy, UCLA-led Study Says
Over the past few years, body mass index, a ratio of a person's height and weight, has effectively become a proxy for whether a person is considered healthy. Many U.S. companies use their employees' BMIs as a factor in determining workers' health care costs. And people with higher BMIs could soon have to pay higher health insurance premiums, if a rule proposed in April by the Equal Employment Opportunity Commission is adopted.
Anti-bullying Program Focused on Bystanders Helps the Students Who Need It the Most
Many programs to reduce bullying in primary and secondary schools have proven ineffective, but a new UCLA-led study finds one that works very well. The study of more than 7,000 students in 77 elementary schools in Finland found that one program greatly benefited the mental health of sixth-graders who experienced the most bullying. It significantly improved their self-esteem and reduced their depression.
Protein Combination Improves Bone Regeneration, UCLA Study Shows
A UCLA research team has found a combination of proteins that could significantly improve clinical bone restoration. The findings may be a big step toward developing effective therapeutic treatments for bone skeletal defects, bone loss and osteoporosis.
Moon Was Produced by a Head-on Collision Between Earth And a Forming Planet
The moon was formed by a violent, head-on collision between the early Earth and a "planetary embryo" called Theia approximately 100 million years after the Earth formed, UCLA geochemists and colleagues report.
Electric Patch Holds Promise for Treating PTSD
An average of 30 years had passed since the traumatic events that had left them depressed, anxious, irritable, hypervigilant, unable to sleep well and prone to nightmares. But for 12 people who were involved in a UCLA-led study -- survivors of rape, car accidents, domestic abuse and other traumas -- an unobtrusive patch on the forehead provided considerable relief from post-traumatic stress disorder.
UCLA Psychology Study Explains When And Why Bystanders Intervene in Cyberbullying
People on social media are often unsupportive of cyberbullying victims who have shared highly personal feelings, UCLA psychologists report. Compared to face-to-face situations, bystanders are even less likely to intervene with online bullying. The researchers wanted to learn why bystanders are infrequently supportive of when bullying occurs online.
Dog Domestication May Have Increased Harmful Genetic Changes, UCLA Biologists Report
The domestication of dogs may have inadvertently caused harmful genetic changes, a UCLA-led study suggests. Domesticating dogs from gray wolves more than 15,000 years ago involved artificial selection and inbreeding, but the effects of these processes on dog genomes have been little-studied.
UCLA Researchers Create Exceptionally Strong And Lightweight New Metal
A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has created a super-strong yet light structural metal with extremely high specific strength and modulus, or stiffness-to-weight ratio. The new metal is composed of magnesium infused with a dense and even dispersal of ceramic silicon carbide nanoparticles. It could be used to make lighter airplanes, spacecraft, and cars, helping to improve fuel efficiency, as well as in mobile electronics and biomedical devices.
