Menzies School of Health Research has led the largest-ever study of people living with a unique strain of chronic hepatitis B (C4 hepatitis B)—which predominately affects First Nations Australians in the Northern Territory (NT)—uncovering significant impacts on liver health.

1.970. Chronological age determined within 1.36 years using DNA methylation patterns

  • medicalxpress.com language

Researchers at the Hebrew University have developed an exceptionally accurate method for predicting chronological age from DNA, based on two short genomic regions. Using deep learning networks analyzing DNA methylation patterns at a single-molecule resolution, they achieve age predictions with a median error as low as 1.36 years in individuals under 50. The method is unaffected by smoking, BMI, and sex, and has potential applications in forensics, aging research, and personalized medicine.

More than 7 million people in the United States live with Alzheimer's disease and related dementia (ADRD). Some risk factors for ADRD, like genetics, can't be controlled, but others can be treated. One of the most prevalent is depression (known clinically as major depressive disorder, or MDD). Between 11.1% and 14.7% of ADRD cases—affecting roughly 1 million individuals in the US—are attributable to MDD.

Short-form video isn't new. Before TikTok, there was Vine—a platform that popularized 6-second video clips and helped redefine what it meant to go viral. The "Only a spoonful" of ice cream skit lives rent-free in many netizens' heads. But Vine arrived before mobile internet and algorithmic feeds fully matured. Though the site did not stand the test of time, newer platforms built on its legacy and further refined this engaging media format.

1.987. New blood test predicts multiple sclerosis risk years before symptoms appear

  • 1 month ago schedule
  • medicalxpress.com language

A research team at the Medical University of Vienna has developed a blood test that allows the identification of individuals at risk for developing multiple sclerosis (MS) with a high degree of certainty years before the onset of symptoms. As a result, in the future, diagnostic and therapeutic measures could be taken early enough to delay or even prevent the onset of the disease. The research has just been published in Nature Communications.
