The study also found that a low-fibre diet increased the likelihood of bone stress injuries in both … [Read more...]
Are ‘zombie’ skin cells harmful or helpful?
Senescent skin cells, often referred to as zombie cells because they have outlived their usefulness without ever quite dying, have existed in the human body as a seeming paradox, causing inflammation and promoting diseases while also helping the immune system to heal wounds. New findings may explain why: Not all senescent skin cells are the same. Researchers from Johns … [Read more...]
Increasing Physical Activity in Middle Age May Protect Against Alzheimer’s Disease
An increase in physical activity between the ages of 45 and 65 could help prevent Alzheimer's disease, while inactivity may be detrimental to brain health.

New Strategy May Enable Cancer Monitoring From Blood Tests Alone
A new, error-corrected method for detecting cancer from blood samples is much more sensitive and accurate than prior methods and may be useful for monitoring disease status in patients following treatment, according to a study by Weill Cornell Medicine and New York Genome Center investigators. The method, based on whole-genome sequencing of DNA, also represents an important … [Read more...]
Eat Better, Breathe Easier? Research Points to Link Between Diet, Lung Cancer
For cancers of organs like the liver, the long-term impact of our diet has been well studied -- so much so that we have guidance about red meat, wine and other delicacies. A new study from researchers at University of Florida Health looks at another kind of organ whose cancer risk may be affected by poor diet: the lungs. The study was funded by several National Institutes … [Read more...]
Mother’s High-Fat Diet Can Cause Liver Stress in Fetus
When mothers eat a diet high in fat and sugars, their unborn babies can develop liver stress that continues into early life. A new study published in the journal Liver International sheds light on changes to the fetus's bile acid, which affects how liver disease develops and progresses. Bile acids typically help with digestion and absorb dietary fats in the small … [Read more...]

How Hungry Fat Cells could Someday Starve Cancer to Death
Scientists transformed energy-storing white fat cells into calorie-burning 'beige' fat. Once implanted, they outcompeted tumors for resources, beating back five different types of cancer in lab experiments. Liposuction and plastic surgery aren't often mentioned in the same breath as cancer. But they are the inspiration for a new approach to treating cancer that uses … [Read more...]
