Mind control using sound waves? We ask a scientist how it works.

Oxford University's Antoine Jerusalem explains the art of ultrasound neuromodulation.

At the moment, non-invasive neuromodulation – changing brain activity without the use of surgery – looks poised to usher in a new era of healthcare. Breakthroughs could include the better management of Parkinson's and Alzheimer's disease, reducing the pain of migraines or even reversing cognitive disorders caused by brain injury.

How does screen time affect kids’ brains? The first results of a landmark study are alarming.

The National Institutes of Health recently began a $300-million study to examine the effects of screen time on developing brains.

  • The study uses MRI scans to track the changes in the brains of children who use screens at varying amounts.
  • Early results revealed that kids who use screens for more than 7 hours per day show physical changes to the brain in the form of premature thinning of the cortex.
  • It will likely be decades before scientists truly understand how smartphones and other technologies affect the brain.

How hands-on learning fires up your brain

To strengthen your mind, work with your hands, says former astronaut Leland Melvin.

  • Learning is a mental and physical pursuit, says retired astronaut Leland Melvin.
  • Recalling his childhood, Melvin explains how working with his dad to turn a $500 bread truck into a family RV camper ultimately made him a better astronaut, able to maneuver the $2-billion dollar Columbus Laboratory out of the payload bay of a shuttle and attach it to the International Space Station.
  • Experiential learning — like hands-on DIY, engineering kits, and Duplo games — wires your brain for problem solving from a young age. It's a leg-up we can all give to the children in our lives.
  • "[W]hen we let [kids] build and create and it's meaningful and it helps them solve a problem, that gets them thinking about how they can be change makers themselves and how they can be scientists and engineers," says Melvin.

Cutting social media use to 30 mins per day significantly reduces depression and loneliness

Who would have thought that endlessly comparing your life to others would make you feel bad?

  • Prior research has shown that social media usage can negatively impact our mental health, but until now, very few studies have shown this experimentally.
  • A study from the University of Pennsylvania asked study participants to limit their social media usage so their resulting mental health could be measured.
  • The results tell us how to regulate our social media usage to improve our well-being.
