Study finds significant variation in anatomy of human guts
by North Carolina State University New research finds there is significant variation in the anatomy of the human digestive system, with pronounced differences possible between healthy individuals. The finding has implications for understanding the role that the digestive tract’s anatomy can play in affecting human health, as well as providing potential insights into medical diagnoses and...

Newly discovered anatomy shields and monitors brain
by University of Rochester Medical Center New study in Nature Aging describes a new anatomical structure in the brain called SLYM, an abbreviation of Subarachnoidal LYmphatic-like Membrane, that acts as a barrier and a platform from which immune cells can monitor the brain.

Video: Cleaning system of the brain captured in 3-D footage
by Lund University Credit: Unsplash/CC0 Public Domain All biological activity in the body produces waste that needs to be removed. This is also true for the brain. Previous research has shown that mouse brains have their own cleaning system, which is called the glymphatic system. Researchers in Lund have now taken the next step and examined...

Anatomy of an acne treatment
Sarecycline, a drug approved for use in the United States in 2018, is the first new antibiotic approved to treat acne in more than 40 years. Now, researchers at Yale and the University of Illinois-Chicago have discovered how its unique chemical structure makes it effective. Their new study is the most detailed biological analysis to...

Study shows highly reproducible sex differences in aspects of human brain anatomy
by National Institutes of Health A scientific analysis of more than 2,000 brain scans found evidence for highly reproducible sex differences in the volume of certain regions in the human brain. This pattern of sex-based differences in brain volume corresponds with patterns of sex-chromosome gene expression observed in postmortem samples from the brain’s cortex, suggesting...

Researchers develop a new ultrafast insulin
by Taylor Kubota, Stanford University Researchers at Stanford University are developing a new insulin formulation that begins to take effect almost immediately upon injection, potentially working four times as fast as current commercial fast-acting insulin formulations. The researchers focused on so-called monomeric insulin, which has a molecular structure that, according to theory, should allow it...

Temple scientists regenerate neurons in mice with spinal cord injury and optic nerve damage
New research by scientists at the Lewis Katz School of Medicine Temple University (LKSOM) shows, however, that gains in functional recovery from these injuries may be possible, thanks to a molecule known as Lin28, which regulates cell growth. In a study published online in the journal Molecular Therapy, the Temple researchers describe the ability of...

Anatomy of surprise: Scientists discover hidden blood networks that cross through bone
For years, physiologists looking closely at bones noticed something puzzling. It was a microscopic prison break, blood cells slipping unseen from the enclosed depths of the bone marrow into the general circulation. “We have the bone marrow, which produces the blood cells, and when you need them, you need them urgently. But how do they...
