A new Tel Aviv University study finds that certain environmental conditions may precipitate structural changes that take place in myelin sheaths in the onset of multiple sclerosis (MS). Myelin sheaths are the "insulating tape" surrounding axons; axons carry electrical impulses in neurons.

Omega-3 fatty acids, such as those typically contained in fish oil, may suppress the growth and spread of breast cancer cells in mice. This is according to a new study in the journal Clinical & Experimental Metastasis, which is published under the Springer imprint. According to lead author, Saraswoti Khadge of the University of Nebraska Medical Centre in the US, fatty acids stopped further delayed tumors from forming, and blocked the cancerous cells from spreading to other organs in mice. The researchers speculate that this might be because of the way in which omega-3 fatty acids support the body’s immune and anti-inflammatory systems.

Results from a research study published in Nature Communications show how the inner ear processes speech, something that has until now been unknown. The authors of the report include researchers from Linköping University.

A line of zebrafish specially generated at the University of Oregon had a key role in discovering the cause of Saul-Wilson syndrome, a rare disease seen in just 15 cases worldwide.

Most people who need open heart surgery to repair damaged heart valves are aged 65 or older. The American Heart Association (AHA) estimates that nearly 8 million people have had heart surgeries. However, we don’t fully understand the effects of heart surgery on an older adult’s cognition (the ability to remember, think, and make decisions).

Well-balanced and predominantly plant-based diets can lead to improved nutrient levels, reduce premature deaths from chronic diseases by more than 20%, and lower greenhouse gas emissions, fertilizer application, and cropland and freshwater use, globally and in most regions, a new study reports.
