Air pollution may reduce health benefits of exercise

A new study found that long-term exposure to toxic air can weaken the health benefits of regular exercise. The study analyzed data from over 1.5 million adults and found that people living in high pollution areas had a reduced risk of dying, but not eliminated, despite exercising regularly. Clean air can still enhance health gains, wit...

Platform-independent experiment shows tweaking X’s feed can alter political attitudes

A new study using an AI-powered browser extension reveals that even small changes in exposure to hostile political content on X (formerly Twitter) can measurably influence feelings toward opposing political parties. The findings provide direct causal evidence of the impact of algorithmically controlled post ranking on a user's social m...

Study: New protocol for Treg expansion uses targeted immunotherapy to reduce transplant complications

A new protocol for Treg expansion uses targeted immunotherapy to reduce transplant complications, boosting survival rates while preserving anti-cancer immunity. The protocol, led by Robert Levy, uses TL1A-Ig fusion protein and low-dose IL-2 to stimulate specific receptors on Tregs, promoting a safer environment for stem cell transplants.

Hematological and biochemical serum markers in breast cancer: Diagnostic, therapeutic, and prognostic significance

Serum markers such as NLR, PLR, ESR, LDH, ALP, creatine kinase-BB, SUA, CRP, and CA 15-3/27.29 have been linked to breast cancer diagnosis, prognosis, and therapeutic monitoring. These biomarkers offer affordable, non-invasive, and accessible diagnostic strategies for bridging the diagnostic gap in low-resource settings.
