Researchers simulate how hackers could randomly strand internet-connected cars to cause widespread traffic gridlock. Even with conservative estimates, stalling 20% of cars during rush hour could freeze traffic solid and debilitate emergency vehicles.
KAUST researchers have developed a single microchip that integrates sensing, energy-harvesting, current-rectifying, and energy-storage functions. The chip uses ruthenium oxide as the common electrode material, enabling miniaturization of self-powered sensor devices.
Daily intake of Montmorency tart cherry juice improved memory scores among adults aged 65-73, with notable reductions in movement time and errors during visual and spatial working memory tasks. Compliance was high, but larger studies are warranted to confirm findings.
