Chemists, materials scientists and nanoengineers at UC San Diego have created what may be the ultimate natural sunscreen. In a paper published in the American Chemical Society journal ACS Central Science, they report the development of nanoparticles that mimic the behavior of natural melanosomes, melanin-producing cell structures that protect our skin, eyes and other tissues from the harmful effects of ultraviolet radiation.
Reducing 'computational sprawl' with brain-inspired computing and re-thinking computing architecture from the ground up were two of many far-reaching ideas proposed at the eighth annual Non-Volatile Memories Workshop.
A new study suggests that an aggressive reef competitor—the Threespot Damselfish—may have impeded the recovery of Caribbean long-spined sea urchin populations after a mysterious disease outbreak caused a massive die-off of these animals over three decades ago.
Engineers at the University of California San Diego have developed a miniature device that’s sensitive enough to feel the forces generated by swimming bacteria and hear the beating of heart muscle cells.
Man-made pollution in eastern China’s cities worsens when less dust blows in from the Gobi Desert, according to a new study published May 11 in Nature Communications. That’s because dust plays an important role in determining air temperature and thereby promotes winds to blow away man-made pollution. Less dust means the air stagnates, with man-made pollution becoming more concentrated and sticking around longer.
Researchers at University of California San Diego School of Medicine, with collaborators across the nation, have determined that magnetic resonance elastography (MRE) can be an accurate, non-invasive tool to identify liver fibrosis in children. Nonalcoholic fatty liver disease (NAFLD) is now the most common cause of chronic liver disease in children, and scarring of the liver, known as fibrosis, is a major determinant of clinical outcomes.
