Prebiotics are an intriguing potential approach to curbing some of the severe side effects that life-saving immunotherapy treatments can wreak on the gut, according to an analysis of recent studies and clinical trials by researchers at the University of Michigan Rogel Cancer Center. Rather than trying to introduce beneficial strains of […]

A team of researchers from the University of Michigan and the Henry Ford Health System is shedding new light on important differences in triple-negative breast cancer tumours from African, African American and white patients. The work was conducted using mouse xenograft models implanted with patient breast tumours. The findings, which […]

A major challenge in the study of aging and age-related disease is establishing the direction of causation. A great many mechanisms of aging are known, but it is difficult to firmly establish the relationships between them. The body is made up of many interacting systems, and changes in any one […]

A new study from the Maurice and Gabriela Goldschleger School of Dental Medicine at Tel Aviv University (TAU) has found that the excessive use of smartphones and social media can lead to problems sleeping; drowsiness and fatigue during the day; teeth-grinding; and pain in the mouth muscles and jaws. The researchers compared about 600 […]

A study of Japanese university students and recent graduates has revealed that writing on physical paper can lead to more brain activity when remembering the information an hour later. Researchers say that the unique, complex, spatial and tactile information associated with writing by hand on physical paper is likely what […]

A groundbreaking new study led by University of Minnesota Twin Cities researchers from both the College of Science and Engineering and the Medical School shows for the first time that lab-created heart valves implanted in young lambs for a year were capable of growth within the recipient. The valves also […]

Have you forgotten where you laid your keys?  Ever wondered where you had parked your car? Or having trouble remembering the name of the new neighbor? Unfortunately, these things seem to get worse as one gets older. A big question for researchers is where does benign forgetfulness end and true […]

In a recent study testing the effects of exercise on overall metabolism, researchers at Oregon State University found that even a single session of moderate aerobic exercise makes a difference in the cells of otherwise sedentary people. Mitochondria are the part of the cell responsible for the biological process of […]

In researching the causes and potential treatments for degenerative conditions such as Alzheimer’s or Parkinson’s disease, neuroscientists frequently struggle to accurately identify cells needed to understand brain activity that gives rise to behaviour changes such as declining memory or impaired balance and tremors. A multidisciplinary team of the Georgia Institute […]

The small intestine is ground zero for survival of animals. It is responsible for absorbing the nutrients crucial to life and it wards off toxic chemicals and life-threatening bacteria. In a new study published in the journal Science, Yale researchers report the critical role played by the gut’s immune system […]

New insights into a little-understood DNA structure could provide the basis for new cancer therapies. DNA is usually depicted as double-stranded, but not much is known about parts of the genome that adopt four-stranded structures known as quadruplexes. UC Riverside researchers have discovered that they play a key role in […]

Researchers here note an association between vision impairment and mortality in later life. This has the look of a correlation that exists because aging is a global process at work throughout the body. It stems from the accumulation of a few classes of cell and tissue damage. That damage causes […]
