Cells used to study the human blood brain barrier in the lab aren’t what they seem, throwing nearly a decade’s worth of research into question, a new study from scientists at Columbia University Vagelos College of Physicians and Surgeons and Weill Cornell Medicine suggests. The team also discovered a possible way to correct the error,

Americans may not be too busy to exercise after all.

In many Latin American countries, the procedure is sky rocketing, reaching more than 50 percent in some. While C-sections

In the first such clinical trial in the United States, physician-scientists with the University of Maryland School of Medicine (UMSOM) are investigating the use of MRI-guided focused ultrasound to open the blood-brain barrier. The trial will be conducted with patients undergoing brain cancer surgery at the University of Maryland Medical Center (UMMC). The blood-brain barrier

Immunotherapies are treatments that stimulate a patient’s immune cells to attack tumors. They can be very effective in melanoma—a common and aggressive form of skin tumor—but nonetheless fail in the majority of patients. To address this, researchers are trying to identify the factors that enable successful immunotherapy, as well as those that may limit it.

Blocking the activity of an enzyme that has a key role in the generation of recurring seizures may provide a new way to treat epilepsy that is resistant to anti-seizure drugs, according to a study of rats and mice published in JNeurosci. One-third of people with epilepsy, one of the most common neurological disorders, do
