Mini golf as art

Students in U of M assistant professor Chris Larson’s sculpture course, “Site, Environment, Community,” probably weren’t expecting mathematics and power tools to play such an important role in their creation of art.

But then, it’s not every class that gets to design and build two holes of mini golf for a world-renowned museum like The Walker Art Center.

This year marks the 25th anniversary of the Walker’s outdoor sculpture garden, and the 6th year the museum has hosted its summer treat, the 15-hole Artist-Designed Mini Golf course. (more…)

Of Aging Bones and Sunshine

Study at Berkeley Lab’s Advanced Light Source Links Vitamin D Deficiency to Accelerated Aging of Bones

Everyone knows that as we grow older our bones become more fragile. Now a team of U.S. and German scientists led by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley has shown that this bone-aging process can be significantly accelerated through deficiency of vitamin D – the sunshine vitamin.

Blind(fold)ed by Science: Study Shows the Strategy Humans Use to Chase Objects

Vision and Hearing Work Together in the Brain to Help Us Catch a Moving Target

COLUMBUS, Ohio — A new study has found that chasing down a moving object is not only a matter of sight or of sound, but of mind.

The study found that people who are blindfolded employ the same strategy to intercept a running ball carrier as people who can see, which suggests that multiple areas of the brain cooperate to accomplish the task.

Regardless of whether they could see or not, the study participants seemed to aim ahead of the ball carrier’s trajectory and then run to the spot where they expected him or her to be in the near future. Researchers call this a “constant target-heading angle” strategy, similar to strategies used by dogs catching Frisbees and baseball players catching fly balls. (more…)

Is sexual addiction the real deal?

Controversy exists over what some mental health experts call “hypersexuality,” or sexual “addiction.” Namely, is it a mental disorder at all, or something else? It failed to make the cut in the recently updated Diagnostic and Statistical Manual of Mental Disorders, or DSM-5, considered the bible for diagnosing mental disorders. Yet sex addiction has been blamed for ruining relationships, lives and careers.

Now, for the first time, UCLA researchers have measured how the brain behaves in so-called hypersexual people who have problems regulating their viewing of sexual images. The study found that the brain response of these individuals to sexual images was not related in any way to the severity of their hypersexuality but was instead tied only to their level of sexual desire.

Study investigates extraordinary trout with tolerance to heavily polluted water

New research from the University of Exeter and King’s College London has shown how a population of brown trout can survive in the contaminated waters of the River Hayle in Cornwall where metal concentrations are so high they would be lethal to fish from unpolluted sites. (more…)

Water Geysers on Saturn’s Moon

A new study published in Nature this week describes the forces that control the jets of water and organic material that erupt from the icy surface of Enceladus, a moon of Saturn. UA scientists contributed data to the study.

The intensity of the jets of water ice and organic molecules that shoot out from Saturn’s moon Enceladus depends on the moon’s proximity to the planet, according to data obtained by NASA’s Cassini spacecraft. The finding, detailed in the journal Nature this week, is the first clear observation that shows the Enceladus plume varies in a predictable manner. (more…)

Eye-tracking could outshine passwords if made user-friendly

It’s a wonder we still put up with passwords.

We forget our highly secretive combinations, so we frequently have them reset and sent to our cellphones and alternative email addresses. We come up with clever jumbles of letters and words, only to mess up the order. We sit there on the login screen, desperately punching in a code we should know by heart. (more…)
