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.
Arguing against the current conventional wisdom – that there is an evolved capacity for number and arithmetic that we share with other species – Rafael Nunez says numerical cognition is not biologically endowed.
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.
