Assessment of insulin resistance using TyG index flags rapid cognitive decline in Alzheimer's patients

Insulin resistance detected by routine triglyceride-glucose (TyG) index can flag people with early Alzheimer's who are four times more likely to present rapid cognitive decline, according to new research presented at the European Academy of Neurology (EAN) Congress 2025.

Study reveals intercellular flow as crucial factor in tissue mechanics

Water makes up around 60 percent of the human body. More than half of this water sloshes around inside the cells that make up organs and tissues. Much of the remaining water flows in the nooks and crannies between cells, much like seawater between grains of sand.

New brain study explains why some pain becomes chronic

A new study reveals that when we experience short-term (acute) pain, the brain has a built-in way to dial down pain signals - like pressing the brakes - to keep them from going into overdrive.

Targeting ST6Gal-I shows promise in reducing Alzheimer’s disease pathology

A recent study published in Engineering has provided novel insights into the involvement of α2,6-sialylation in Alzheimer's disease (AD), revealing that the ablation of α2,6-sialyltransferase-I (ST6Gal-I), an enzyme responsible for α2,6-sialylation, can downregulate BACE1 expression and suppress the production of amyloid-β42 (Aβ42) plaques, which are hallmarks of AD.

Multiple brain profiles underlie the same symptoms in depression

A novel study aimed at disentangling the neurological underpinnings of depression shows that multiple brain profiles may manifest as the same clinical symptoms, providing evidence to support the presence of both one-to-one and many-to-one heterogeneity in depression.

Placenta and prenatal hormones may drive human brain evolution

The placenta and the hormones it produces may have played a crucial role in the evolution of the human brain, while also leading to the behavioral traits that have made human societies able to thrive and expand, according to a new hypothesis proposed by researchers from the Universities of Cambridge and Oxford.
