Added sugar intake was positively associated with ischemic stroke and abdominal aortic aneurysm, although the highest risks of most outcomes were found in the lowest intake category; positive linear associations were found between toppings intake and abdominal aortic aneurysm, and between sweetened beverage intake and ischemic stroke, heart failure, atrial fibrillation, and abdominal aortic aneurysm; negative linear associations were found between treats intake (pastries, ice cream, chocolate, and sweets) and all outcomes, and between toppings intake (table sugar, honey, jams, and marmalades) and heart failure and aortic stenosis.

Bottom-up nano- to micro-fabrication is crucial in modern electronics and optics. Conventional multi-scale array fabrication techniques, however, are facing challenges in reconciling the contradiction between the pursuit of better device performance and lowering the fabrication cost and/or energy consumption. Chang et al. introduce a facile mixed-metal array fabrication method based on guided self-assembly of polymerizing organometallic adducts derived from the passivating oxides of a ternary liquid metal to create mixed metal wires.
