Feb 28th 2025, 13:50

Researchers found that peristaltic pump flow mechanically breaks supersaturation to induce amyloid formation by hen egg white lysozyme, a-synuclein, amyloid b 1-40, and b2-microglobulin. The high shear stresses induced by peristaltic flow likely reflect those that occur the blood and cerebrospinal fluid, suggesting that this factor could promote amyloidosis.

Feb 28th 2025, 11:40

A study has provided new insights into the role of the brain as a crucial control center and the origin of obesity and type 2 diabetes. The hormone insulin plays a key role in the development of obesity. The brain's sensitivity to insulin is associated with long-term weight gain and unhealthy body fat distribution. What specific functions does insulin perform in the brain, and how does it affect individuals of normal weight?

Feb 27th 2025, 21:29

Air pollution contributes to nearly 7 million premature deaths each year, and its effects go far beyond the lungs. Breathing in wildfire smoke or automobile-related city smog doesn't just increase the risk of asthma and heart disease -- it may also contribute to brain conditions as diverse as Alzheimer's and autism. Scientists have discovered how a chemical change in the brain -- which can be triggered by inflammation and aging as well as toxins found in air pollution, pesticides, wildfire smoke and processed meats -- disrupts normal brain cell function. Known as S-nitrosylation, this chemical change prevents brain cells from making new connections and ultimately results in cellular death, the team discovered.

Feb 27th 2025, 12:55

The ability to make the connection between an event and its consequences -- experts use the term associative learning -- is a crucial skill for adapting to the environment. It has a huge impact on our mental health. A study shows that children of primary school age demonstrate the highest learning performance in this area. The results pave the way for a fresh perspective on associative learning disorders, which are linked to the development of mental illness later in life.

Feb 25th 2025, 20:12

The new research reveals how a protein in brain cells may drive Parkinson's onset -- and offers a possible explanation for why Parkinson's is much more common in men.

Feb 25th 2025, 12:24

New research suggests that certain antidepressants can accelerate cognitive decline in people with dementia. At the same time, some drugs appear to be less harmful than others, which can help doctors make better treatment decisions, according to the study.

Feb 25th 2025, 12:18

A new definition of dyslexia is needed to more accurately describe the learning disorder and give those struggling with dyslexia the specific support they require, says new research.
