A new study shows that a type of natural sugar called trehalose triggers an important cellular housekeeping process in immune cells that helps treat atherosclerotic plaque. The image shows a cross section of a mouse aorta, the main artery in the body, with a large plaque. Straight red lines toward the upper left are the wall of the aorta. Yellow areas are where housekeeping cells called macrophages are incinerating cellular waste. Credit: Ismail Sergin

In vivo effect on HMVP2 tumor growth of treatment with CUR, UA, RES and their combinations. HMVP2 cell spheroids were injected subcutaneously into the flank of male FVB/N mice. Mice were fed ad libitum with semipurified AIN76A-based diet containing CUR, UA, RES or their combinations of two natural compounds. Body weight (a), food consumption (b), tumor volume (c) and tumor weight (d) are shown as mean ± SEM. One-way ANOVA with significance at p < 0.05 was used. Statistical significance is shown as different from control (a), CUR (b), UA (c) and RES (d)

Synthetic process of metal-organic framework nanosheet array. Figure 1 Metal salts and substrate are firstly mixed together in an aqueous solution, and then introduces the organic ligand. Next, the MOF nanosheet array grows on the surface of substrate via a dissolution-crystallization mechanism.

The internal components of a battery-free pacemaker introduced this week by Rice University and the Texas Heart Institute. The pacemaker can be inserted into the heart and powered by a battery pack outside the body, eliminating the need for wire leads and surgeries to occasionally replace the battery.
