Americans consume 70,000 particles of microplastics per year
Date:  June 5, 2019
Source:  American Chemical Society
Summary:  Since the mass production of plastics began in the 1940s, the versatile polymers have spread rapidly across the globe. Although plastics have made life easier in many ways, disposing of the materials is a growing problem. Now, researchers estimate that the average American consumes more than 70,000 particles of microplastics per year, though the health effects of that consumption are unclear. https://www.sciencedaily.com/releases/2019/06/190605100332.htm


Gut microbes eat our medication

Summary:  Researchers have discovered one of the first concrete examples of how the microbiome can interfere with a drug's intended path through the body. Focusing on levodopa (L-dopa), the primary treatment for Parkinson's disease, they identified which bacteria out of the trillions of species is responsible for degrading the drug and how to stop this microbial interference.  https://www.sciencedaily.com/releases/2019/06/190613143629.htm


Scaffold helps cells repair torn meniscus in lab tests
Scaffold-aided repair led to stronger meniscus, laying groundwork for potential human tests

Date: June 19, 2019
Source:  Duke University Medical Center
Summary:  About a million times a year, Americans with a torn meniscus in their knee undergo surgery in hopes of a repair. Certain tears can't be fixed or won't heal well, and many patients later suffer osteoarthritis. To improve meniscus healing, Duke scientists have developed a scaffold derived from a pig's meniscus, which performed better in lab tests than healing without a scaffold.   https://www.sciencedaily.com/releases/2019/06/190619142540.htm

Summary:  Good heart and lung (cardiorespiratory) fitness in middle age is associated with a lower long term risk of chronic lung disease (COPD), suggests new research. https://www.sciencedaily.com/releases/2019/06/190618192032.htm


Higher fitness level can determine longer lifespan after age 70
For older people, fitness may be more informative than traditional cardiovascular risk factors

Date:  March 6, 2019
Source:  American College of Cardiology
Summary:  Researchers have uncovered one more reason to get off the couch and start exercising, especially if you're approaching your golden years. Among people over age 70, physical fitness was found to be a much better predictor of survival than the number of traditional cardiovascular risk factors. https://www.sciencedaily.com/releases/2019/03/190306081829.htm

Alzheimer's family history risk may show as memory deficit even for those in their 20s
Study indicates lack of cure for dementia highlights need for early detection; early intervention

Date:  June 20, 2019
Source:  The Translational Genomics Research Institute
Summary:  Results from a study of nearly 60,000 individuals suggest those at higher risk of developing Alzheimer's disease due to family history may demonstrate changes in memory performance as early as their 20s. Researchers gathered the data through an online word-pair memory test called MindCrowd, one of the world's largest scientific assessments of how healthy brains function. https://www.sciencedaily.com/releases/2019/06/190620100034.htm

Summary:  Annually, about 790,000 Americans suffer a heart attack, which leaves damaged scar tissue on the heart and limits its ability to beat efficiently. But what if scientists could reprogram scar tissue cells called fibroblasts into healthy heart muscle cells called cardiomyocytes? For the first time, researchers developed a stable, reproducible, minimalistic platform to reprogram human fibroblast cells into cardiomyocytes. https://www.sciencedaily.com/releases/2019/06/190620153522.htm


Just 20 minutes of contact with nature will lower stress hormone levels, reveals new study

Summary:  Taking at least 20 minutes out of your day to stroll or sit in a place that makes you feel in contact with nature will significantly lower your stress hormone levels. That's the finding of a study that has established for the first time the most effective dose of an urban nature experience. Healthcare practitioners can use this discovery to prescribe 'nature-pills' in the knowledge that they have a real measurable effect. https://www.sciencedaily.com/releases/2019/04/190404074915.htm
