Researchers in Sweden and Finland have created the CORE model, a simple blood test that predicts liver disease risk with striking accuracy. Unlike current methods, it works for the general population and can be used in everyday primary care settings. With validation across multiple countries and a web tool already available, the breakthrough could lead to much earlier detection of cirrhosis and liver cancer.

Researchers have revealed how polymyxins, crucial last-resort antibiotics, break down bacterial armor by forcing cells to overproduce and shed it. Astonishingly, the drugs only kill bacteria when they’re active, leaving dormant cells untouched. This discovery could explain recurring infections and inspire strategies to wake bacteria up before treatment.

Scientists discovered that high-fat junk food disrupts memory circuits in the brain almost immediately. Within just four days, neurons in the hippocampus became overactive, impairing memory. Restoring glucose calmed the neurons, showing that interventions like fasting or dietary shifts can restore brain health. This could help prevent obesity-related dementia and Alzheimer’s.

Human fertility hinges on a delicate molecular ballet that begins even before birth. UC Davis researchers have uncovered how special protein networks safeguard chromosomes as eggs and sperm form, ensuring genetic stability across generations. Using yeast as a model, they revealed how crossovers between chromosomes are protected for decades in female eggs, preventing errors that could lead to infertility, miscarriage, or conditions like Down syndrome.
