"Emergency response modernized in Tijuana with help from UC San Diego undergrads"
In Tijuana, a border city of about 1.8 million in the grips of an unprecedented spike in violence, an average ambulance response time is 24 minutes-- sometimes too late to save a person's life. That's why a group of students at UC San Diego's Jacobs School of Engineering teamed up with Cruz Roja (Red Cross) to create a mobile application to make it easier for emergency medical crews to provide lifesaving help.

"Adding alkali metal to perovskite solar cells changes the solar game"
Researchers from Georgia Tech, UC San Diego and MIT have discovered that adding alkali metal to perovskite solar cells could enable energy devices to last longer and maintain better performance. Recently, there has been a push to try different perovskite recipes that will yield better efficiencies. This includes adding cesium and rubidium cations. But it was not previously known why this worked. The researchers used high-intensity X-ray mapping to get a better glimpse of perovskites at the nanoscale and see how each individual element plays a role in improving the performance of the device.

"Alkali metals improve efficiency of perovskite solar cells"
Perovskite-based solar cells are simple and cheap to produce, offer flexibility that could unlock a wide new range of installation methods and places, and in recent years have reached energy efficiencies approaching those of traditional silicon-based cells. But figuring out how to produce perovskite-based solar cells that last longer than a couple of months has been a challenge. Now researchers have reported new findings about that could lead the way to better perovskite devices. The researchers described in detail how adding alkali metal to traditional perovskites improves performance.

"Tiny, Motorized Pill Delivers Vaccine to Mouse Intestine"
A new type of vaccine vehicle--this one literally has a teeny tiny motor--can drive itself to the mucosal linings of mouse intestines, potentially allowing for broader protection against infection. Nanoengineers Liangfang Zhang and Joseph Wang at the University of California San Diego teamed up to design an ingestible device that can navigate the digestive system of rodents, stick itself to the mucosal lining of the gut, and deliver its payload. Aside from obviating the need for shots, the team says, the motorized vaccine may have another crucial benefit: its ability to build mucosal immunity.

"UCSD students will try to launch rocket 6 miles into atmosphere"
A team of UC San Diego engineering students has built a liquid-fueled rocket that it will attempt to launch roughly six miles into the atmosphere during a collegiate competition in the Mojave Desert. The 21-foot tall Vulcan II rocket is scheduled to lift off from a site near Edwards Air Force Base on March 2 as part of a contest sponsored by Friends of Amateur Rocketry and the Mars Society.

"Understanding why cesium and rubidium salt improve the yield of perovskite solar cells"
Researchers at the University of California San Diego explain how adding small amounts of cesium or rubidium salt to perovskite-based solar cells can increase performance by around 2%. According to their paper published in Science, the addition of alkali metal to lead-halide perovskites was a well-known process to increase performance, but no explanation of why this was possible was available. The discovery could rapidly advance work to identify the perfect mix of compounds and elements in a perovskite layer for use in solar cells.
"Avoiding The Ouch: Scientists Are Working On Ways To Swap The Needle For A Pill"
Many vaccines and some medicines, such as insulin, have to be delivered by injection. That's a pain, both for patients and for health care providers. But two groups of researchers are trying to put some of these medications in pill form to avoid the needle. One team of scientists, from the University of California San Diego, developed an ingestible microrocket, about the size of a grain of sand, that is designed to zip past the stomach and into the small intestine, where it releases its payload -- a vaccine protein.
"Test Your Assumptions With UC San Diego Citizen Science Online Tool"
A tool out of UC San Diego is empowering regular citizens to design experiments to test hypotheses and recruit participants, becoming scientists themselves. The tool is called Galileo and encourages participants to test their intuitions by asking questions like, can a vegan diet improve energy levels? Or does drinking coffee every day reduce the quality of sleep? The lead developer is a computer science PhD student.

"A 3D Bioprinter Makes a Spinal Cord Implant in 1.6 Seconds"
3D bioprinting -- building tissues by putting down layers of cells and other materials -- has led to the manufacturing of human tissues including corneas, skin, and blood vessels. Now, a team at the University of California San Diego, is raising the bar. In a paper published this week in the journal Nature Medicine, they describe a 3D-printed spinal cord implant that restored function in the hind limbs of rats with spinal cord injuries. It is the first 3D printing of a complex central nervous system structure, according to the authors.

"UC San Diego researchers use stem cells, 3D-printing to treat spinal cord injuries"
Researchers at UC San Diego published a study this week, showing that a mix of 3D printing and stem cell therapy can be used to treat severe spinal cord injuries. Scientists from the schools of engineering, biomedicine and neuroscience collaborated on the project, which they say is a huge breakthrough for people with paralysis. In tests on rodents, the 3D spinal cord and stem cells spurred new neuron growth and helped restore function.

"Stem cell-filled implant restores some spinal cord function in UC San Diego animal study"
Stem cell-filled implants helped repair spinal cord damage in animals, according to a study led by UC San Diego scientists. If all goes well, the implants with neural stem cells could be ready for testing in human patients in a few years. Rats with completely severed spinal cords regained some voluntary motion after getting the implants, said the study, published Monday in the journal Nature Medicine.
"Bio-Printers Are Churning out Living Fixes to Broken Spines"
For doctors and medical researchers repairing the human body, a 3D printer has become almost as valuable as an x-ray machine, microscope, or a sharp scalpel. Researchers say that bio-printed tissue can be used to test the effects of drug treatments, for example, with an eventual goal of printing entire organs that can be grown and then transplanted into a patient. The latest step towards 3D-printed replacements of failed human parts comes from a team at the University of California San Diego. It has bio-printed a section of spinal cord that can be custom-fit into a patient's injury.

"UCSD Scientists Demonstrate Use of 3D Printing with Stem Cells for Spinal Repair"
UC San Diego researchers have for the first time used 3D printing technology to create a spinal cord and implant it with neural stem cells into rats with spinal cord injuries, the university announced Monday. The implant is designed to promote nerve growth and regrowth for victims of severe spinal cord injuries, according to the researchers. For the rats in the study, the 3D printed spinal cords spurred tissue growth, the regeneration of nerve cell extensions called axons and expansion of the implanted neural stem cells into the rat's natural spinal cord.
