| Vitamins, supplements are a 'waste of money' for most Americans Posted: 21 Jun 2022 08:47 AM PDT Scientists say for non-pregnant, otherwise healthy Americans, vitamins are a waste of money because there isn't enough evidence they help prevent cardiovascular disease or cancer. They've written an editorial in support of new recommendations that state there was 'insufficient evidence' that taking multivitamins, paired supplements or single supplements can help prevent cardiovascular disease and cancer in otherwise healthy, non-pregnant adults. |
| Global AFib study finds simple ablation has best outcomes Posted: 21 Jun 2022 08:47 AM PDT Results from one of the largest global studies of atrial fibrillation (AFib) procedures show that the simple approach is usually best when it comes to ablation, a procedure where physicians destroy or ablate cardiac tissue to correct irregular heart rhythms. Researchers found that using advanced image-guided technology to more aggressively target diseased areas of the heart that cause arrythmias didn't lead to better outcomes for patients -- and put some at higher risk of strokes, according to new results. |
| Scientists identify a possible source for Charon's red cap Posted: 21 Jun 2022 07:56 AM PDT Scientists combined data from NASA's New Horizons mission with novel laboratory experiments and exospheric modeling to reveal the likely composition of the red cap on Pluto's moon Charon and how it may have formed.
