A new study has found a strong relationship between bacterial imbalances in the oral microbiome and a key biomarker of Alzheimer’s. This new research focuses on the link between amyloid levels and different oral bacteria species in healthy older adults.

Scientists may have identified three new subtypes of multiple sclerosis. Analyzing thousands of MRI scans, AI algorithms uncovered patterns regarding which areas of the brain are affected first, which could lead to more focused treatment options.

Researchers are closer to an objective blood test for mood disorders, with a new study describing a panel of blood-based biomarkers that can distinguish between depression and bipolar disorder, and measure the future risk of developing these conditions.

More than one in 10 adults suffer from chronic rhinosinusitis, an inflammatory sinus condition. A new brain imaging study suggests the disease is linked with functional brain connectivity changes that could explain cognitive problems such as brain fog.

An advanced microscopy technique has snapped “super-resolution” 3D images inside the brains of living mice. The method is so precise it imaged the tiny twigs on the branches of neurons, and could watch how they changed over the course of a few days.

A striking new study has found gene expression can dramatically increase in some brain cells hours after a person dies. The researchers suggest scientists studying post-mortem brain tissue must take into account these significant changes in future work.

For some people a small irritation can wreck their day, while others can shake off minor problems and move on. A new study is suggesting persistent activity in the amygdala could be why some are unable to move on from momentary negative experiences.

A landmark proof-of-concept study reveals a novel brain-machine interface using ultrasound tracking brain activity to predict subsequent motor movements. The preliminary research suggests a non-invasive way of controlling computers with one's mind.

A new study suggests handwriting on paper leads to greater brain activity and memory retention than using a stylus on a tablet. The researchers hypothesize the spatial details of writing on paper may explain why it enhances the encoding of information.

Facebook has taken the unusual step of revealing its next-gen augmented reality gear at a working prototype stage, including a staggering neuro-motor controller that reads nerve impulses in your wrist at single-neuron resolutions.

With long space missions a real prospect in the near future, scientists are trying to find ways to mitigate the negative impacts of reduced gravity on the human body. A new study suggests microgravity can negatively affect cognitive performance.

Unfortunately there isn’t much that doctors can do to repair the damage after a spinal cord injury. But UCLA researchers have shown in tests in mice that injections of a porous scaffold material can help the body patch up the damage.
