Using advanced fabrication techniques, engineers at the University of California San Diego have built a nanosized device out of silver crystals that can generate light by efficiently “tunneling” electrons through a tiny barrier. The work brings plasmonics research a step closer to realizing ultra-compact light sources for high-speed, optical data processing and other on-chip applications.
The governing board of the California Institute for Regenerative Medicine (CIRM) unanimously approved this week two grants worth more than $2.2 million to University of California San Diego School of Medicine researchers investigating stem cell-based therapies for a rare genetic disorder that affects the heart and a chronic, progressive affliction of the lungs.
“It may not be easy to run an engineering school, but it’s impossible without your friends,” said Jacobs School of Engineering Dean Albert P. Pisano at the annual Charles Lee Powell Foundation graduate fellowship luncheon. “To the ladies and gentlemen of the Powell Board—I am grateful for that friendship which was paid forward through other deans and other times. I, too, am standing on the shoulders of all the previous investment, and I do really appreciate all of that.”
By doping alumina crystals with neodymium ions, engineers at the University of California San Diego have developed a new laser material that is capable of emitting ultra-short, high-power pulses—a combination that could potentially yield smaller, more powerful lasers with superior thermal shock resistance, broad tunability and high-duty cycles.
A new discovery in how heart muscles maintain their shape in fruit flies sheds light on the crucial relationship between cardiac function, metabolism, and longevity. Researchers from the University of California San Diego discovered that maintaining high levels of the protein vinculin—which sticks heart muscle cells to one another—confers health benefits to fruit flies. Their work shows that fruit flies bred to produce 50 percent more vinculin enjoyed better cardiovascular health and lived a third of their average life span longer.
Researchers led by a University of California San Diego team have published work in the journal Nature Energy that explains what’s causing the performance-reducing “voltage fade” that currently plagues a promising class of cathode materials called Lithium-rich NMC (nickel magnesium cobalt) layered oxides.
