Muscle loss in elderly linked to blood vessels' failure to dilate

Research at the University of Texas Medical Branch found that elderly people's muscles don't respond to insulin by expanding their blood vessels like younger people do. This response is necessary for muscle protein synthesis and growth, with implications for improving strength and health in older adults.

Living wills are poor predictors of actual treatment preferences at the end of life

A recent study published in Journal of Palliative Medicine found that living wills often do not accurately reflect patients' actual treatment preferences at the end of life. The authors propose revising living wills to include more realistic scenarios and estimates of treatment effectiveness to guide advance care decisions.

Keeping an ear out for kin

Researchers discovered that bats can differentiate between their own and different species using individualized echolocation calls, similar to how humans recognize voices. This ability may provide an advantage in hunting grounds, while also influencing community-level interactions.

More than 60 percent of teachers have voice problems

A study by researchers at the University of Malaga found that 62.7% of early childhood and primary education teachers suffer from voice disorders on a daily or weekly basis. The study highlights the psychosocial dimensions associated with these disorders, including less social support, role conflict, and reduced respect for their work.

Greenland rapidly rising as ice melt continues

Scientists from the University of Miami found that Greenland's ice is melting rapidly, causing the land underneath to rise by nearly one inch per year. The study suggests that if current trends continue, this acceleration could lead to a significant increase in global sea level rise.

The Alzheimer's solution

The Alzheimer's Solution proposes community centers for dementia care, addressing the need for novel solutions to address this disease. The centers would provide programs of care, treatment, and prevention, taking a family-oriented and personalized approach.

Preserving memory with age

Researchers found that longevity treatments have different impacts on learning and memory in C. elegans, a nematode species. Dietary restriction improved early adult memory but declined with age, while reduced Insulin/IGF-1 signaling enhanced memory performance but failed to preserve it with age.
