UCLA Researchers Find Evidence for Water Ice Deposits and Organic Material on Mercury

Planetary scientists have identified water ice and unusually dark deposits within permanently shadowed areas at Mercury’s north pole.

Using data collected by NASA’s MESSENGER spacecraft, a team from UCLA crafted the first accurate thermal model of the solar system’s innermost planet, successfully pinpointing the extremely cold regions where ice has been found on or below the surface.

The researchers say the newly discovered black deposits are a thin crust of residual organic material brought to the planet over the past several million years through impacts by water-rich asteroids and comets. (more…)

Molecular ‘tweezers’ break up toxic aggregations of proteins in mouse model

Last March, researchers at UCLA reported the development of a molecular compound called CLR01 that prevented toxic proteins associated with Parkinson’s disease from binding together and killing the brain’s neurons.

Building on those findings, they have now turned their attention to Alzheimer’s disease, which is thought to be caused by a similar toxic aggregation or clumping, but with different proteins, especially amyloid-beta and tau. (more…)

New Global Subsidy that Provides Access to Most Effective Malaria Drugs Shows Promise

UCLA infectious diseases doctor played key role in finance strategy for therapy

A new international program, conceived in part by a UCLA physician, has rapidly transformed access to lifesaving anti-malarial drugs by providing cheap, subsidized artemisinin-based combination therapies in seven African countries that account for a quarter of the world’s malaria cases.

The first independent evaluation of the Affordable Medicines Facility–malaria (AMFm) program was recently published in the journal The Lancet. The program is based at the Global Fund in Geneva, an international financing institution dedicated to disbursing funds to prevent and treat infectious diseases. The evaluation shows that the program improved access to key artemisinin combination therapies, or ACTs, which offer broader protection and less antibiotic resistance than anti-malaria medications currently available in those African nations.

Women with stable but not-so-sexy mates become more distant, critical during periods of high fertility

Long after women have chosen Mr. Stable over Mr. Sexy, they struggle unconsciously with the decision, according to a new study by UCLA researchers who look at subtle changes in behavior during ovulation.

At their most fertile period, these women are less likely to feel close to their mates and more likely to find fault with them than women mated to more sexually desirable men, the research shows. (more…)

Science Supports Sex Addiction as a Legitimate Disorder

UCLA researchers test proposed criteria for diagnosing ‘hypersexual disorder’

The idea that an individual might suffer from a sexual addiction is great fodder for radio talk shows, comedians and late night TV. But a sex addiction is no laughing matter. Relationships are destroyed, jobs are lost, lives ruined.

Yet psychiatrists have been reluctant to accept the idea of out-of-control sexual behavior as a mental health disorder because of the lack of scientific evidence.

Now a UCLA-led team of experts has tested a proposed set of criteria to define “hypersexual disorder,” also known as sexual addiction, as a new mental health condition. (more…)

Breakthrough Technique Images Breast Tumors in 3-D with Great Clarity, Reduced Radiation

Like cleaning the lenses of a foggy pair of glasses, scientists are now able to use a technique developed by UCLA researchers and their European colleagues to produce three-dimensional images of breast tissue that are two to three times sharper than those made using current CT scanners at hospitals. The technique also uses a lower dose of X-ray radiation than a mammogram.

These higher-quality images could allow breast tumors to be detected earlier and with much greater accuracy. One in eight women in the United States will be diagnosed with breast cancer during her lifetime.

The research is published the week of Oct. 22 in the early edition of the journal Proceedings of the National Academy of Sciences. (more…)

Foster Kids do Equally Well when Adopted by Gay, Lesbian or Heterosexual Parents

High-risk children adopted from foster care do equally well when placed with gay, lesbian or heterosexual parents, UCLA psychologists report in the first multi-year study of children adopted by these three groups of parents.

The psychologists looked at 82 high-risk children adopted from foster care in Los Angeles County. Of those children, 60 were placed with heterosexual parents and 22 were placed with gay or lesbian parents (15 with gay male parents and seven with lesbian parents). (more…)

Taking Race Out of the Equation in Measuring Women’s Risk of Osteoporosis and Fractures

For women of mixed racial or ethnic backgrounds, a new method for measuring bone health may improve the odds of correctly diagnosing their risk of osteoporosis and bone fractures, according to a UCLA-led study.

Currently, assessing osteoporosis and the risk of fractures from small accidents like falls requires a bone density scan. But because these scans don’t provide other relevant fracture-related information, such as bone size and the amount of force a bone is subjected to during a fall, each patient’s bone density is examined against a national database of people with the same age and race or ethnicity.
