Scientists at Northwestern University have developed a rapid PCR test that can diagnose hepatitis C in about 15 minutes using whole blood samples. Adapted from a COVID-19 detection system and built on the DASH rapid PCR platform, the test aims to enable same-day treatment and bolster global efforts to eliminate the virus, with early evaluations showing accuracy comparable to existing commercial platforms.
Researchers at the University of Adelaide have found that blocking the enzyme Caspase-2, previously seen as a potential treatment for fatty liver disease, may increase the risk of chronic liver damage and cancer over time. In genetically modified mice lacking functional Caspase-2, liver cells grew abnormally large and accumulated genetic damage, leading to inflammation, scarring, and tumors. The findings, published in Science Advances, challenge the development of Caspase-2 inhibitors.

Researchers at Mayo Clinic have discovered a rare mutation in the MET gene that directly causes metabolic dysfunction-associated steatotic liver disease, a condition affecting about one-third of adults worldwide. The finding, based on a family case without typical risk factors, suggests similar variants may contribute to the disease in many others. Published in Hepatology, the study highlights the role of genomic analysis in uncovering hidden genetic causes.
Researchers at the University of Barcelona have discovered that combining two existing medications, pemafibrate and telmisartan, significantly reduces liver fat in animal models of metabolic dysfunction-associated steatotic liver disease (MASLD). This approach could offer a safer treatment option for the condition, which affects about one in three adults worldwide. The findings highlight the potential of drug repurposing to address a disease with limited current therapies.
