Researchers have developed a new brain imaging method that uses pulsed laser light to monitor cerebral blood flow more accurately than more traditional methods.

Researchers say specific gut bacteria could play a significant role in the development of Type 2 diabetes. People with higher levels of the gut bacteria Coprococcus tend to have higher insulin sensitivity, while those with higher levels of Flavonifractor have lower levels of insulin sensitivity.

Common levels of pollution from traffic can impair brain function within a matter of hours, a new study reports. Just two hours of exposure to diesel exhaust impairs functional connectivity in the brain.

Even a simple movement like pushing a button sends ripples of activity throughout networks of neurons spanning across the brain, new research shows. The finding highlights just how complex the human brain is, challenging the simplified textbook picture of distinct brain areas dedicated to specific functions.

In many neurodegenerative conditions, brain changes occur before symptoms emerge. But now, researchers from Japan have found a new way to distinguish these conditions in the early stages according to changes in brain activity patterns.

Researchers have developed an AI model capable of accurately capturing cognitive decline by measuring how fast the brain is aging. Findings reveal sex-specific differences in how the brain ages. Certain regions of the brain age faster in males than in females, and vice versa. The model has far-reaching applications that extend into personalized medicine and can be used to design patient-tailored interventions for a wide range of brain health concerns.

Finally this week, a healthy diet is associated with slower memory decline, finds a decade-long study of older adults in China, published in The BMJ.
