Why do eyelids sag with age? UCLA study answers mystery
Many theories have sought to explain what causes the baggy lower eyelids that come with aging, but UCLA researchers have now found that fat expansion in the eye socket is the primary culprit.

CD4+ T lymphocytes, or simply CD4 T cells, are the “brains” of the immune system, coordinating its activity when the body comes under attack. They are also the cells that are attacked by HIV, the devastating virus that causes AIDS and has infected roughly 40 million people worldwide. The virus slowly eats away at CD4 T cells, weakening the immune system.
UCLA researchers discovered that an FDA-approved drug reverses the brain dysfunction inflicted by a genetic disease called tuberous sclerosis complex (TSC). Because half of TSC patients also suffer from autism, the findings offer new hope for addressing learning disorders due to autism.
More than half of all older adults complain about having difficulties sleeping. Most don’t bother seeking treatment. Those who do usually turn either to medications, which can lead to other health problems, or behavior therapies, which are costly and often not available close to home.
Got memory problems? If you suffer from obstructive sleep apnea, your brain tissue could be to blame.
For the first time, UCLA researchers have discovered that people with sleep apnea show tissue loss in brain regions that help store memory.
Stem cell researchers at UCLA were able to grow functioning cardiac cells using mouse skin cells that had been reprogrammed into cells with the same unlimited properties as embryonic stem cells.
People who do not have HIV but seek antiretroviral medications following high-risk sexual encounters are very likely to complete the full monthlong drug regimen, according to a new UCLA AIDS Institute study. Moreover, there is a strong demand for publicly available post-exposure prophylaxis among high-risk populations in Los Angeles County.
Most women, and large numbers of men, are interested in having cosmetic surgery, UCLA scientists report in the October issue of the Journal of Plastic and Reconstructive Surgery.
It is already known that a person’s social environment can affect his or her health, with those who are socially isolated — that is, lonely — suffering from higher mortality than people who are not.
In the first large scale, multiethnic study of its kind, researchers have confirmed the role played by three particular molecules known as cytokines as a cause of Type 2 diabetes, and further, have identified these molecules as early biological markers that may be used to more accurately predict future incidences of diabetes among apparently healthy individuals.
PG-13 films have lots of “happy violence,” say UCLA researchers. Borrowing from the late communications theorist George Gerbner, happy violence is that which is “cool, swift and painless.” PG-13 films don’t consider the consequences of violent acts, such as injury, death and the shattered lives of the people involved.
