Space geodetic observations help reveal variations in Earth’s surface loads

A research team used space geodetic observations to study seasonal and intra-seasonal signal variations in the Earth's surface loads, finding subsidence and uplift in regions of positive and negative mass anomalies. The results indicate that space geodesy offers an effective method for studying surface loads and crustal movements.

BU study: PrEP to reduce HIV incidence not available in one in three New England colleges and universities

A new study found that more than one-third of New England colleges and universities do not offer PrEP, a medication that reduces HIV incidence by over 90%. The lack of access hinders HIV prevention efforts among young gay, bisexual, and other men who have sex with men, who account for 80% of new HIV infections among youth ages 13–24.

New study reveals why defense against brain corrosion declines in people with Alzheimer’s disease

Researchers at Case Western Reserve University found that a protein called Slingshot Homolog-1 (SSH1) stops Nrf2 from carrying out its protective biological activity, leading to the decline of brain defense in Alzheimer's disease. Genetically eliminating SSH1 increases Nrf2 activation and slows the development of oxidative damage.

BU study finds volume of liver resection during gallbladder surgery doesn't significantly affect overall survival

A new study by Boston University researchers found that the volume of liver resected during gallbladder cancer surgery does not significantly affect overall survival rate when all cancer is removed. In contrast, larger liver resections were associated with more complications and longer hospital stays.
