Engineers have developed a tiny, ultra-low power chip that could be injected just under the surface of the skin for continuous, long-term alcohol monitoring. The chip is powered wirelessly by a wearable device such as a smartwatch or patch. The goal of this work is to develop a convenient, routine monitoring device for patients in substance abuse treatment programs.

Researchers have developed a stretchable, flexible patch that could make it easier to perform ultrasound imaging on odd-shaped structures, such as engine parts, turbines, reactor pipe elbows and railroad tracks—objects that are difficult to examine using conventional ultrasound equipment. The ultrasound patch is a versatile and more convenient tool to inspect machine and building parts for defects and damage deep below the surface.

A new computational resource called Recon3D provides a 3D view of genes, proteins and metabolites involved in human metabolism. Researchers used the tool to map disease-related mutations on proteins and also probed how genes and proteins change in response to certain drugs. The work provides a better understanding of disease-causing mutations and could enable researchers to discover new uses for existing drug treatments.

Computers have helped researchers develop a new phosphor that can make LEDs cheaper and render colors more accurately. An international team led by engineers at UC San Diego first predicted the new phosphor using supercomputers and data mining algorithms, then developed a simple recipe to make it in the lab. Unlike many phosphors, this one is made of inexpensive, earth-abundant elements and can easily be made using industrial methods. As computers predicted, the new phosphor performed well in tests and in LED prototypes.

Back in 1956, IBM built the first disk drive. It was the size of two refrigerators and held a total of five megabytes—enough storage capacity to handle about 30 seconds of video. That’s a stark contrast to today’s hard drives, which can hold tens of terabytes of data and fit in the palm of your hand. One of the key innovators who helped drive this remarkable evolution is Eric Fullerton, a professor of electrical and computer engineering and nanoengineering at UC San Diego.

Nanoengineers at the University of California San Diego have developed an energy-efficient recycling process that restores used cathodes from spent lithium ion batteries and makes them work just as good as new. The process involves harvesting the degraded cathode particles from a used battery and then boiling and heat treating them. Researchers built new batteries using the regenerated cathodes. Charge storage capacity, charging time and battery lifetime were all restored to their original levels.

Researchers at UC San Diego have developed macrophage "nanosponges"—nanoparticles cloaked in the cell membranes of macrophages—that can safely remove sepsis-causing molecules from the bloodstream. In lab tests, these macrophage nanosponges improved survival rates in mice with sepsis.

How sensitive is the human sense of touch? Sensitive enough to feel the difference between surfaces that differ by just a single layer of molecules, a team of researchers at the University of California San Diego has shown.

Researchers have developed new single-cell sequencing methods that could be used to map the cell origins of various brain disorders, including Alzheimer’s, Parkinson’s, schizophrenia and bipolar disorder. By analyzing individual nuclei of cells from adult human brains, researchers have identified 35 different subtypes of neurons and glial cells and discovered which of these subtypes are most susceptible to common risk factors for different brain diseases.
