Dartmouth researcher finds a new role for the benefits of oxygen

A Dartmouth researcher found that oxygen can keep dying heart cells alive by providing spikes of oxygen. This discovery could lead to new treatments for congestive heart failure, which is often caused by cell death due to lack of oxygen. The research suggests that controlled breathing exercises may also have health benefits.

NASA's moon landing remembered today as a promise of a 'future which never happened'

Researchers claim NASA portrayed astronauts as pioneering cowboys in its images of the moon landing, promising a future that never materialized. The study analyzed over 400 memory cards from visitors to the National Space Centre and found half contained a reference to the moon landing as a glimpse into a future that never came true.

Cancer survivors in rural areas forgo health care because of cost

A recent study published in Cancer Epidemiology, Biomarkers & Prevention found that rural cancer survivors are 66% more likely to forgo medical care and 54% more likely to forgo dental care because of financial concerns. This disparity suggests that health insurance coverage alone may not ensure equal access to healthcare.
