DEATH STAR BACTERIAL STRUCTURES COULD BE DRUG DELIVERY TOOL

By scraping tubeworms off the bottom of boats in San Diego Bay to study them, San Diego State University researchers discovered a beneficial bacterium that aids in establishing colonies could also be a boon for human health, because the same process might already take place in the human gut.

While examining this bacterium that causes metamorphosis in the humble tubeworm, marine microbiologist Nicholas Shikuma discovered that the nanoscale syringe-like structures produced by it – a structure nicknamed the Death Star for the effect it has – could be used in the future to deliver novel therapeutics or vaccines to targeted cells and tissues in humans.

A ROBOTIC LOOK AT AGING

An octogenarian reaches for a glass of water on the table. Because of miscommunication between the aging brain and muscles in the hand, and the time-delay in the brain signal reaching the hand—a common occurrence for older adults – he overreaches and knocks the glass to the floor.

Now, a robot manipulator that has been trained and configured in a SDSU lab to mimic the human brain may eventually help avoid such mishaps by bringing stability and safety in motion.

Peiman N. Mousavi’s research team has spent four years working on algorithms that can successfully command the robot to mimic the human brain and the jerky actions of an elderly person. This has helped advance the understanding of why the miscommunication and subsequent time-delay happens between the brain and muscles.

THE PATH TO PERSONALIZED MEDICINE

How does a tumor escape the normal checks and balances that keep cells healthy and cancer-free?

The SDSU chemistry professor Christal Sohl studies how enzymes, the protein workhorses of human cells, go rogue in ways that lead to cancer. Unlocking the relationship between enzymes and cancer could help researchers develop new treatments for patients.

“Once we know, at the molecular level, how the activity of the enzyme changes to support tumor growth, we can ultimately design personalized medicine that targets rogue enzymes in our quest to cure cancer,” Sohl explained.

TOOL HELPS FISHERMEN, CONSERVATIONISTS

Historically, fisheries and the conservation community have struggled to find common ground. The tension between one side's desire to increase profits and the other’s to preserve endangered or protected marine species that can be killed as bycatch has made it difficult to find solutions that satisfy both.

Now, a new online tool developed by researchers at San Diego State University in collaboration with the National Oceanic and Atmospheric Administration and other universities could win support from both groups. EcoCast provides computer-generated maps to help fishermen target productive fishing spots while alerting them to areas likely to harbor protected species.

MATERIAL ENGINEERING IN THE FINAL FRONTIER 

If humans are ever to colonize the moon or Mars, they’re going to need habitats, tools and other physical resources to keep them alive. Researchers are tinkering with ways to fabricate tools and building supplies from the raw minerals available on extraterrestrial terrain.

Randall German, professor emeritus at SDSU, is considering how space pioneers might accomplish material engineering in space using sintering, a manufacturing process that turns a powdered substance into a solid mass using heat and pressure. To get a better understanding of how gravitational conditions in space affect the sintering process, German sent materials into space in a collaboration with SpaceX.

MAKING VR LEARNING A REALITY

The waxing and waning phases of the moon arise from the three-dimensional interplay between the positions of the sun, moon and Earth. It can be a complex concept for students to get their heads around—but it might become easier thanks to virtual reality programs that allow learners to watch these moon phases play out from a sort of interstellar birds-eye view.

“When we learned about the moon phases, we used foam balls attached to popsicle sticks,” said Harsimran “Sim” Baweja, the SDSU Instructional Technology Fellow for immersive learning. “How awesome would it be to float in space and see how the sun’s light illuminates the moon and creates the phases? Things like this are possible today thanks to virtual reality.”

RAISING RESEARCHERS

More than 15 percent of Student Research Symposium participants receive financial aid from SDSU, and that’s no coincidence. Scholarship support alleviates some of the financial burden for students and gives them time to participate in activities that build leadership, research and public service skills.

"I didn't really know what I wanted to do for a long time before I got into research. In joining a lab I found my path, I found out that I wanted to go to graduate school. It really set me up for my career for the rest of my life," says Greg Dawson, a biochemistry major.
