Studies reveal skull as unexpected source of brain immunity

The immune system is the brain’s best frenemy. It protects the brain from infection and helps injured tissues heal, but it also causes autoimmune diseases and creates inflammation that drives neurodegeneration. Two new studies in mice suggest that the double-edged nature of the relationship between the immune system and the […]

Healing hydrogels

Hydrogels are polymer materials made mostly from water. They can be used in a wide range of medical and other applications. However, previous incarnations of the materials suffered from repeated mechanical stress and would easily become deformed. A novel crystal that can reversibly form and deform, allows hydrogels to rapidly […]

Tiny implant cures diabetes in mice without triggering immune response

A team of researchers led by diabetes specialists and biomedical engineers at Washington University School of Medicine in St. Louis and Cornell University has demonstrated that using a miniscule device, they can implant insulin-secreting cells into diabetic mice. Once implanted, the cells secrete insulin in response to blood sugar, reversing […]

A connectomic study of a petascale fragment of human cerebral cortex

The human brain is the most interesting object in neuroscience. Recently, researchers from Harvard University and Google released a 1.4-petabyte dataset of a small sample of the human cerebral cortex (a surface layer of the brain, responsible for higher-level cognitive functions). The sample has been imaged at 4nm-resolution using electron […]

Case Western Reserve-led research team aims to determine which diabetic individuals can successfully donate corneas for transplant (and which should not)

About a third of the corneal transplant surgeries in the United States involve people with diabetes who donate their corneas after death. The number of corneal transplants has grown over the last decade, but through continuous research, the medical community has learned that not all corneal tissue from diabetics may […]

VUMC team discovers new genetic disease

Researchers at Vanderbilt University Medical Center have discovered a new genetic disease that causes a severe form of neurogenic orthostatic hypotension, a rapid drop in blood pressure upon standing that can cause fainting. The rare condition, which they named familial autonomic ganglionopathy, is caused by variations in the CHRNA3 gene, […]

Scientists Identify Genes Involved in Neuron Development

Neurons result from a highly complex and unique series of cell divisions. For example, in fruit flies, the process starts with stem cells that divide into mother cells (progenitor cells), which then divide into precursor cells that eventually become neurons. A team from the University of Michigan, spearheaded by graduate […]
