Coaxing hair growth in aging hair follicle stem cells

Researchers at Northwestern University have discovered a way to soften stiff hair follicle stem cells, enabling them to grow hair again. By boosting the production of microRNA-205, they promote hair growth in both young and old mice, offering potential for human hair regrowth.

How genetics influences our body weight beyond the genes

Researchers have identified microRNA-7 as a non-classic genetic risk factor for hereditary obesity. The molecule affects energy balance and appetite regulation in humans and mice, highlighting the need to examine non-genetic factors in gene-based studies. This discovery may lead to new therapeutic approaches for treating obesity.

New sleep molecule discovered: “It shows just how complex the machinery of sleep is”

Researchers have discovered a new sleep molecule, microRNA-137 (miR-137), that regulates hypocretin levels for normal sleep. The study found that miR-137 is associated with hypocretin regulation and sleep disorders such as narcolepsy and insomnia.
