Breakthrough study reveals the secrets behind cordierite’s anomalous thermal expansion

Researchers at Queen Mary University of London uncover new insights into cordierite's unusual ability to resist changes in size despite significant temperature fluctuations. The team's simulations accurately reproduced experimental data, providing a comprehensive explanation for the material's behaviour at both low and high temperatures.

A battle of rafts: How molecular dynamics in CAR T cells explain their cancer-killing behavior

Researchers investigated how two CAR T cells kill cancer with distinct signaling domains. CD28.ζ-CAR molecules work quickly and efficiently, while 4-1BB.ζ-CAR molecules linger in lipid rafts for sustained collaborative killing of tumor cells. This study aims to design CAR molecules maximizing antitumor activity beyond B cell malignancies.

Medicare rules may reduce prescription steering

Pharmacy benefit managers (PBMs) steer Medicare patients to their own pharmacies, with PBM-owned pharmacies capturing over 60% market share in certain drug classes. The study suggests that the 'any willing pharmacy' rules may be preventing PBMs from gaining significant market share in Medicare.
