  • The study found that vegans were 43% more likely to suffer fractures than meat eaters.
  • Similar results were observed for vegetarians and fish eaters, though to a lesser extent.
  • It's possible to be healthy on a vegan diet, though it takes some strategic planning to compensate for the nutrients that a plant-based diet can't easily provide.

  • Fragile X syndrome is a genetic disorder caused by changes in a gene that scientists call the "fragile X mental retardation 1 (FMR1)" gene. People who have FXS or autism often struggle with sensitivity to sound.
  • According to the research team, FXS is caused by the disruption of a gene. By disrupting that same gene in zebrafish larvae, they can examine the effects and begin to understand more about this disrupted gene in the human brain.
  • Using the zebrafish, Dr. Constantin and the team were able to gather insights into which parts of the brain are used to process sensory information.

  • 3D bioprinting involves using printers loaded with biocompatible materials to manufacture living or lifelike structures.
  • In a recent paper, a team of engineers from Carnegie Mellon University's College of Engineering developed a new way to 3D bioprint a realistic model of the human heart.
  • The model is flexible and strong enough to be sutured, meaning it could improve the ways surgeons train for cardiac surgeries.

COVID-19 amplified America’s devastating health gap. Can we bridge it?

The COVID-19 pandemic is making health disparities in the United States crystal clear. It is a clarion call for health care systems to double their efforts in vulnerable communities.

  • The COVID-19 pandemic has exacerbated America's health disparities, widening the divide between the haves and have nots.
  • Studies show disparities in wealth, race, and online access have disproportionately harmed underserved U.S. communities during the pandemic.
  • To begin curing this social aliment, health systems like Northwell Health are establishing relationships of trust in these communities so that the post-COVID world looks different than the pre-COVID one.
