"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.

"12 innovations that will revolutionize the future of medicine"
We've seen an explosion of tech-driven gains and innovations that have the potential to reshape many aspects of health and medicine. All around us, technologies from artificial intelligence (AI) to personal genomics and robotics are advancing exponentially, giving form to the future of medicine. These include a wearable patch, smaller than a postage stamp, that keeps the beat -- heartbeat, that is. It measures blood pressure deep within the body by emitting ultrasonic waves that pierce the skin and bounce off tissues and blood, feeding data back to a laptop.

With the help of a 3-D printed hydrogel implant, researchers have demonstrated that they can restore leg movement in rats with severe spinal cord injuries. Using a fast, light-based printing technique, the team tailored the implants to precisely fit a cut or tear in a spinal cord, guiding nerve cells to grow across the injury site and reestablish neural connection.

"Groundbreaking Research In 2018 That Furthered The Study Of Alzheimer's, Cancer And Blood Pressure"
In large part because of the support of the NIH, scientists across the United States and around the globe conduct wide-ranging research to enhance health, lengthen life and reduce illness and disability. This research includes a project, led by Sheng Xu, assistant professor at the University of California San Diego, to engineer a blood pressure sensor that uses ultrasound technology and can be worn as a flexible skin patch. The technology could replace other methods of monitoring blood pressure in the future.
"Could the Future Be Powered by Salt? This Researcher Thinks It's Possible"
If battery innovation were a cocktail party, lithium ion would be the one sucking up all the oxygen in the room, telling too many jokes and barely letting anyone get a word in edge wise. But these lithium ion batteries aren't perfect, explains Shirley Meng, a nanoengineering professor at the University of California San Diego. They're expensive and require the use of cobalt, which can sometimes be a conflict mineral. Meng and colleagues recently started looking into the question of whether our infatuation with lithium ion might be overshadowing other more promising areas of battery research.
