New study identifies concerning gaps between how human radiologists score the accuracy of AI-generated radiology reports and how automated systems score them. Researchers designed two novel scoring systems that outperform current automated systems that evaluate the accuracy of AI narrative reports. Reliable scoring systems that accurately gauge the performance of AI models are critical for ensuring that AI continues to improve and that clinicians can trust them.

T cells experience different mechanical signals in different tissues. Researchers have engineered a tissue-mimicking hydrogel model to show that more elastic tissues induce T cells to become effector-like T cells with strong tumor-killing potential, while more viscous tissues induce them to become memory-like T cells. This new concept could help advance adaptive T cell therapies by producing desired patient-specific T cell populations in the dish that could provide stronger effects when infused back into the same patient.

Researchers have discovered a new combination of drugs that significantly boosts the efficacy of anti-cancer treatments for colorectal cancers implanted in mice. The results also highlight a previously unknown mechanism of DNA repair. Source: National Cancer Institute

A team of researchers has developed a new method for controlling lower limb exoskeletons using deep reinforcement learning. The method enables more robust and natural walking control for users of lower limb exoskeletons. The study, "Robust walking control of a lower limb rehabilitation exoskeleton coupled with a musculoskeletal model via deep reinforcement learning," is available open access.

Attaching sugar molecules to proteins can affect protein activities in the cell — and this behavior can be exploited to treat diffuse large B-cell lymphomas (DLBCL), according to a recent study. The finding sets up an unexpected approach to targeted therapy for this aggressive disease. Source: National Cancer Institute

Therapeutic nanocarriers engineered from adult skin cells can curb inflammation and tissue injury in damaged mouse lungs, new research shows, hinting at the promise of a treatment for lungs severely injured by infection or trauma. Source: Ohio State University/Science Daily
