7 Researchers identify vulnerability in glioblastoma cancer defenses¶
Researchers at Ohio State University identified the SET protein as a therapeutic target in glioblastoma, finding that blocking it restores PP2A enzyme activity and increases cancer cells' sensitivity to radiation in preclinical models. An FDA-approved antipsychotic drug showed potential to enhance this effect, though human testing is needed to establish safety and efficacy.
- SET protein blocks PP2A enzyme activity in glioblastoma cells
- Blocking SET increased radiation sensitivity in lab and animal models
- FDA-approved antipsychotic drug candidate may enhance PP2A activity
- Approach designed to enhance existing radiation and chemotherapy, not replace them
- Results are preliminary; human testing required

7 Lifestyle program improves cognition 55% more than basic health advice¶
A two-year study of older adults at dementia risk across 11 Latin American countries found that structured lifestyle programs combining exercise, diet, cognitive training, and social engagement produced 55% greater cognitive improvements than standard health advice. The program's success stemmed from regular coaching, cultural adaptation (including salsa, tango, and locally available foods), and support for participants with limited digital access.
- 55% greater cognitive improvement versus general health advice
- Two-year LatAm-FINGERS study across 11 Latin American countries
- Combines exercise, healthy eating, cognitive training, social engagement
- Results published in The Lancet; presented at AAIC 2026 London
- Strongest benefits with regular coaching and structured support
- Culturally adapted: salsa/tango, MIND diet with avocado/quinoa/chia

7 Cancer cells hidden behind protective shields evade chemotherapy¶
Researchers mapped breast tumors and discovered dormant cancer cells sheltered within protective barriers of immune and connective tissue cells. These quiescent cells survive chemotherapy by entering a hibernation-like state and can later reactivate to cause relapse, suggesting future treatments must target both active tumor cells and their protective microenvironment.
- Dormant cancer cells survive chemotherapy and hide from treatment
- Protected by surrounding immune and connective tissue cells
- Can reactivate later to drive relapse and cancer spread
- Study published in Genome Medicine from Imperial College London and UCL
- Future therapies must target both active and dormant cells plus protective tissue environment

6 Sorbitol sugar substitute may convert to fructose in liver¶
Researchers found that sorbitol, a common sugar alcohol in low-calorie foods, can be converted to fructose in the liver with potentially similar metabolic effects.
