A new study suggests a promising alternative to previous attempts to remove the sticky, toxic amyloid beta plaques from brains with Alzheimer's Disease: enhancing the brain's own immune cells to clear these plaques more effectively. The findings could reshape the future of Alzheimer's treatments, shifting the focus from simply removing plaques to harnessing the brain's natural defenses.

Technology is changing how physicians think about assessing patients and, in turn, how patients expect to be able to measure their own health. Apps designed for smartphones and wearable devices can provide unique insights into users' brain health. It is estimated that 55 million individuals worldwide suffer from some form of dementia. Alzheimer's disease and related dementias being the leading causes, with numbers expected to triple by 2050.

Researchers have created washable and durable magnetic field sensing electronic textiles -- thought to be the first of their kind -- which they say paves the way to transform use in clothing. This technology will allow users to interact with everyday textiles or specialized clothing by simply pointing their finger above a sensor.

Injuries to the articular cartilage in different joints, including the knee, are painful and limit mobility. Therefore, researchers are developing cartilage implants using cells from the patient's nasal septum. A recent study shows that giving these cartilage implants more time to mature significantly improved clinical efficacy, even in patients with complex cartilage injuries. This suggests that the method could also be suitable for the treatment of degenerated cartilage in osteoarthritis.

The neurotransmitter glutamate is essential for regulating everything from mood to memory, but it can also encourage a toxic buildup of protein, which can contribute to Alzheimer's and related diseases. Scientists now describe a new approach for counteracting these devastating and often fatal neurodegenerative effects. Researchers made their discovery by studying lab mice as well as human brain 'organoids,' which are rudimentary brain-like structures grown in the lab.
