Scholars say that, overall, gun violence can be reduced by instituting a risk-based approach to firearms possession and purchases

Recent mass killings in Isla Vista, California, and elsewhere have again raised concern among lawmakers and the media about the possible connection between mental illness and gun violence. A new study sets the record straight and recommends an evidence-based approach to limiting firearms fatalities. (more…)

Climate engineering won’t sufficiently stem global warming

orget about positioning giant mirrors in space to reduce the amount of sunlight being trapped in the earth’s atmosphere or seeding clouds to reduce the amount of light entering earth’s atmosphere. Those approaches to climate engineering aren’t likely to be effective or practical in slowing global warming. (more…)

STD may heighten risk of prostate cancer

Could a common sexually transmitted infection boost a man’s risk for prostate cancer?

In a new study, Patricia Johnson, a professor of microbiology, immunology and molecular genetics at the David Geffen School of Medicine at UCLA, explored the connection between prostate cancer and the parasite that causes trichomoniasis, the most common non-viral sexually transmitted infection in men and women.

Brain’s response to sexual images linked to number of sexual partners

UCLA researchers say finding could lead to strategies to reduce risky sex

Like most things, sex requires motivation. An attractive face, a pleasant fragrance, perhaps a sexy image. Yet people differ in their response to sex cues, some react strongly; some don’t. A greater responsiveness to sexual cues might provide greater motivation for a person to act sexually, and risky sexual behaviors typically occur when a person is motivated by particularly potent, sexual reward cues.

Scientists reveal structural secrets of enzyme used to make popular anti-cholesterol drug

In pharmaceutical production, identifying enzyme catalysts that help improve the speed and efficiency of the process can be a major boon. Figuring out exactly why a particular enzyme works so well is an altogether different quest.

Take the cholesterol-lowering drug simvastatin. First marketed commercially as Zocor, the statin drug has generated billions of dollars in annual sales. In 2011, UCLA scientists and colleagues discovered that a mutated enzyme could help produce the much sought-after pharmaceutical far more efficiently than the chemical process that had been used for years — and could do it better than the natural, non-mutated version of the enzyme. But no one quite knew why, until another team of UCLA researchers cracked the mystery. (more…)

Simply being called ‘fat’ makes young girls more likely to become obese

Trying to be thin is like trying to be tall, say UCLA psychologists

Girls who are told by a parent, sibling, friend, classmate or teacher that they are too fat at age 10 are more likely to be obese at age 19, a new study by UCLA psychologists shows.

The study looked at 1,213 African-American girls and 1,166 white girls living in Northern California, Cincinnati and Washington, D.C., 58 percent of whom had been told they were too fat at age 10. All the girls had their height and weight measured at the beginning of the study and again after nine years. (more…)

Misleading mineral may have led to overestimate of water in moon

Discovery of hydrogen-rich apatite in lunar rocks hinted at more watery past. Think again, says UCLA’s Jeremy Boyce.

The amount of water present in the moon may have been overestimated by scientists studying the mineral apatite, says a team of researchers led by Jeremy Boyce of the UCLA Department of Earth, Planetary and Space Sciences.

Boyce and his colleagues created a computer model to accurately predict how apatite would have crystallized from cooling bodies of lunar magma early in the moon’s history. Their simulations revealed that the unusually hydrogen-rich apatite crystals observed in many lunar rock samples may not have formed within a water-rich environment, as was originally expected.
