In the News: Engineers Print an Artificial Beating Heart, FDA May Require Nicotine Reduction in Cigarettes, Men Who Eat Excess Sugar May Develop Mental Health Disorders

Engineers print an artificial beating heart. At ETH Zurich, engineers have successfully created an artificial heart with ventricles that pump a blood-like substance, that weighs the same as a real human heart, and can beat for 30 minutes at a time. Using a mold, they were able to 3-D print a silicone heart which can have major implications on the future of organ donating. They also aim to replace blood pumps, which can have malfunctioning parts that create health issues. This engineering marvel can also eliminate the process of waiting around for a heart when in need of a transplant. With heart disease claiming over 17 million lives across the globe, the speed and convenience of 3-D printing is poised to make a huge difference. (CNN)

FDA may require nicotine reduction in cigarettes. The Food and Drug Administration is considering requiring tobacco companies to reduce the amount of nicotine in their cigarettes in order to make them less addictive. The hope is that this switch will reduce the public’s dependency on cigarettes, preventing the premature death of millions. This change will mark the first time in the history of the FDA that they will regulate nicotine levels in cigarettes. Producers of cigars, hookah tobacco, pipe tobacco, and cigarettes will have until the summer of 2021 to submit their applications for review. Think switching to electronic cigarettes is the answer? Find out why they may be dangerous as well. (NPR)

Men who eat too much sugar may develop mental health disorders. While it’s common knowledge that consuming too much sugar can cause weight gain, inflammatory conditions, and other health issues, it turns out that men are particularly impacted. Research shows that men who eat over 67 grams of sugar on a daily basis have an increased likelihood of developing depression, anxiety, mental health issues, and mood disorders. Compared with participants who ate less than 39.5 grams of sugar daily, excess sugar eaters were 23 percent more likely to showcase these troubling symptoms. Ready to give up sugar?
