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.

Brain disease found in 99% of deceased NFL players. According to a study in the JAMA medical journal, 99 percent of deceased NFL players showed signs of chronic traumatic encephalopathy (CTE), a neurodegenerative brain disease. This condition, often seen in patients with consistent head trauma, causes a buildup of an abnormal protein that can switch off certain neural pathways and cause side effects like depression, anxiety, confusion, poor judgment, lack of control, and even suicidal ideation. Since an autopsy is required to properly diagnose this condition, it can be tricky determining who is currently afflicted with this condition. These findings do show how important it is to take proper care when playing contact sports and to seek help if any of these symptoms appear. Learn more about head injuries here. (CNN)
Owning a dog can improve physical health. While we all know that having a dog can improve overall happiness and improved mental health, a new study in the Journal of Epidemiology and Community Health shows that dog owners are less stressed, more active, have a decreased risk of asthma, and have lowered blood pressure as well. While studying over 3,000 participants ranging in age from 49-91, researchers found that the participants who didn’t own dogs were sedentary for 30 minutes more than the ones who did. These findings may have implications in the senior citizen community, since retirement can often lead to a less active lifestyle. Owning a dog may just be the trick to maintain good health physically and mentally. (TIME)
Sperm count dropping in men across the world. After assessing the results over almost 200 studies conducted on men in North America, Europe, Australia, and New Zealand, researchers found that sperm counts have halved in less than four decades. These findings were the culmination of research from 1973 to 2011. When looking for an explanation, scientists point to an increased exposure to pesticides and plastic chemicals, along with lifestyle issues like obesity, stress, smoking, and a sedentary lifestyle.

Blue light may be hurting your eye health. Since we are on our computers and phones more often than ever before, we are exposed to an unprecedented amount of blue light emissions. Doctors are particularly concerned because the blue light that comes from electronic devices isn’t filtered by the cornea or lens, going straight to the back of the eye instead. While more research is required, some experts worry that this exposure can lead to damaged retinas and other eye health issues. If you want to prevent eye strain, optometrist Janelle Routhier, OD, recommends giving your eyes a break, using a light-reducing app and purchasing blue-blocking lenses.

Time-saving services may boost happiness. According to a study published in the Proceedings of the National Academy of Sciences, spending money on time-saving services may boost overall happiness and satisfaction. Researchers studied the spending habits of 6,000 participants all over the world and found that those who paid for others to clean or cook for them reported increased contentment compared to those who didn’t. Interestingly, under 50 percent of the millionaires surveyed paid to outsource unpleasant tasks, while the others opted to do it themselves, potentially due to feeling guilty or wanting control. Another factor could be the “busy” culture of North America, leading people to juggle all aspects of their lives and enjoying that feeling of being capable. Some experts suggest that letting go and spending a little money to save time can have a huge positive impact on the quality of life. (ABC)

Study reveals why cutting carbs is so challenging. If you’ve ever tried to quit eating carbohydrates and found yourself in a cold sweat gawking at a chocolate chip cookie just days later, you are not alone. Researchers have devoted a lot of time and resources to finding out why cutting carbs is so universally difficult. While many people assume they lack willpower or discipline, it may be a bit more complicated than that. Insulin may play a role in regulating hormones, which is tied to obesity. When insulin is elevated, the body stops burning fat and starts burning carbs, and the more insulin you release, the more you will want to eat carbs. In order to avoid this trap, you need to avoid these types of foods along with social triggers, and plan ahead to make smarter choices. Wondering if your body is resistant to carbs? Take this quiz.

Diet drinks have been linked to weight gain. While diet drinks often seem like ideal alternatives to sugary sodas, it turns out that they may not be any better. New research shows that people who regularly consume diet drinks have an increased BMI and a higher risk of developing heart disease. Belly fat in particular, seems to be linked to diet drinks, which is risky because a high waist circumference increases the odds of developing type 2 diabetes, insulin resistance, and other health problems. While it’s possible that those who drink diet soda are simply eating more sugary foods in addition to these beverages, scientists also believe that artificial sweeteners may be negatively impacting gut health as well. If you want to wean yourself off of diet drinks, try these infused waters instead. (INDEPENDENT)

While many people swear that early morning workouts are the key to success, others cannot fathom waking up earlier than necessary to do any form of exercise.

Speech may reveal signs of mental decline. Researchers at the University of Wisconsin-Madison have found that the way we speak may reveal insights into our mental health. This speech analysis study, which was the largest of its kind, also showed that certain aspects of language may be affected earlier than other parts of the body, allowing physicians to uncover mental deterioration before it becomes too late. With around 47 million people suffering from dementia worldwide, the prospect of an earlier diagnosis is very promising. Another study found that hearing loss may indicate mental decline as well, which can also play a role in catching conditions like Alzheimer’s at the very onset of the illness. (ABC)

While many may assume only a certain amount is beneficial, it turns out that the more cups you drink, the greater the result.

FDA approves new cancer treatment. A new cancer treatment that uses the patient’s immune system to fight their cancer has been approved by the FDA. Known as a “living drug”, this treatment, takes cells from the patient’s body, changes the genes, and then fuses those changed cells back into the body, essentially using its own immune system to fight the disease. While concerns about safety and cost are a factor, this revolutionary treatment is a huge advancement in the field of cancer research. Are you snacking on these six cancer-fighting foods? Add them to your diet today. (NPR)
