Drinking green, oolong, or black tea 4 times per week for 25 years had positive effects on brain structure on the MRI scans of older adults, leading to the brain processing information more efficiently.

Pancreatic adenocarcinoma (PDAC) tends to be resistant to chemotherapy. Inhibiting GSK-3, an enzyme involved with cancer processes, can make PDAC cells more sensitive to a chemotherapy drug, which may improve survival rates.

Measuring how quickly a person's pupil dilates during cognitive tests is a low-cost way to screen people for Alzheimer's disease. Studies have shown that people with mild cognitive impairment had greater pupil dilation.

Lung cancer tends to be resistant to chemotherapy. Lung cancer cells express high amounts of TIMP-1, which increases expression of IL-6 (a chemotherapy-resistant immune modulator). These are called a "destructive duo" in cancer prognosis.
