For the first time, scientists have succeeded in transforming human stem cells into functional lung and airway cells. The advance has significant potential for modeling lung disease, screening drugs, studying human lung development, and, ultimately, generating lung tissue for transplantation.
An experimental device is letting paralyzed people drive wheelchairs simply by flicking their tongue in the right direction. Key to this wireless system: Users get their tongue pierced with a magnetic stud that resembles jewelry and acts like a joystick, in hopes of offering them more mobility and independence.
You may not have heard of “the peanut butter test,” but it could become a fantastically low-cost and non-invasive way to test for Alzheimer’s. After all, what’s less invasive than asking someone to smell some delicious peanut butter?
Alzheimer researchers in Spain have taken a step closer to finding a blood test to help in the diagnosis of Alzheimer’s disease. With approximately 75% of the estimated 36 million Alzheimer’s sufferers worldwide yet to receive a reliable diagnosis, the potential impact on the lives of possible sufferers, present and future, could be huge.
Researchers have pinpointed a catalytic trigger for the onset of Alzheimer’s disease — when the fundamental structure of a protein molecule changes to cause a chain reaction that leads to the death of neurons in the brain.
