Older adults who received the Shingrix shingles vaccine were 24% less likely to be diagnosed with dementia over four years in a study of more than 500,000 people. Researchers estimate the difference could amount to roughly one dementia case prevented for every 17 people vaccinated.

Researchers have found a way to supercharge natural killer cells, powerful immune cells that can attack cancer, so they can penetrate solid tumors and keep fighting once inside. In mice, these specially prepared tissue-resident cells slowed the growth of several tumors, including melanoma and head and neck cancers, and worked even better when paired with the antibody drug cetuximab.

Airborne radiation sensors could help forecast and prevent drought-driven tree mortality

DNA damage is considered one of the major contributors to aging. DHCR24, a multifunctional enzyme located within the endoplasmic reticulum (ER), is closely related to DNA damage. Our previous study showed that DHCR24 could delay vascular endothelial cells (ECs) senescence. The relationship between DHCR24 and DNA damage during ECs senescence requires further investigation. Here, we demonstrate that aging activates ATM-mediated DNA damage response (DDR) in human umbilical vein endothelial cells...
