Heart failure patients may suffer similarly to advanced cancer patients

Researchers found that heart failure patients with poor health status have higher symptom burden, depression, and lower spiritual well-being than cancer patients. Palliative care is underused in heart failure patients, but identifying those who may benefit from it, such as those with low health status scores, can improve quality of life.

Some women more likely to miss or ignore heart attack warning signs

Researchers found that young women with heart attacks often misattributed their symptoms to fatigue or other conditions, failing to connect them with a heart condition. The study suggests that there are large gaps in understanding the symptoms and reasons for delaying prompt care among this age group.

Did the solar system 'bounce' finish the dinosaurs?

A Cardiff University study suggests that the sun's movement through the Milky Way causes comets to collide with Earth every 35-40 million years, coinciding with mass extinctions like the dinosaurs' extinction. This cosmic 'bounce' effect may also have helped life spread by dispersing micro-organisms into space.
