Study: Memories of music cannot be lost to Alzheimer's and dementia

The part of your brain responsible for ASMR catalogs music, and appears to be a stronghold against Alzheimer's and dementia.

Some music inspires you to move your feet, some inspires you to get out there and change the world. In any case, and to move hurriedly on to the point of this article, it's fair to say that music moves people in special ways. 


If you're especially into a piece of music, your brain does something called Autonomous Sensory Meridian Response (ASMR), which feels to you like a tingling in your brain or scalp. It's nature's own little "buzz", a natural reward, that is described by some as a "head orgasm". Some even think that it explains why people go to church, for example, "feeling the Lord move through you", but that's another article for another time. 

Turns out that ASMR is pretty special. According to a recently published study in The Journal of Prevention of Alzheimer's Disease (catchy name!), the part of your brain responsible for ASMR doesn't get lost to Alzheimer's. Alzheimer's tends to put people into layers of confusion, and the study confirms that music can sometimes actually lift people out of the Alzheimer's haze and bring them back to (at least a semblance of) normality... if only for a short while. ASMR is powerful stuff! 

This phenomenon has been observed several times but rarely studied properly. One of the most famous examples of this is the story of Henry, who comes out of dementia while listening to songs from his youth:  

Jeff Anderson, M.D., Ph.D., associate professor in Radiology at the Univerity of Utah Health and contributing author on the study, says  "In our society, the diagnoses of dementia are snowballing and are taxing resources to the max. No one says playing music will be a cure for Alzheimer's disease, but it might make the symptoms more manageable, decrease the cost of care and improve a patient's quality of life."

The “new normal” paradox: What COVID-19 has revealed about higher education

Higher education faces challenges that are unlike any other industry. What path will ASU, and universities like ASU, take in a post-COVID world?

  • Everywhere you turn, the idea that coronavirus has brought on a "new normal" is present and true. But for higher education, COVID-19 exposes a long list of pernicious old problems more than it presents new problems.
  • It was widely known, yet ignored, that digital instruction must be embraced. When combined with traditional, in-person teaching, it can enhance student learning outcomes at scale.
  • COVID-19 has forced institutions to understand that far too many higher education outcomes are determined by a student's family income, and in the context of COVID-19 this means that lower-income students, first-generation students and students of color will be disproportionately afflicted.

Masturbation boosts your immune system, helping you fight off infection and illness

Can an orgasm a day really keep the doctor away?

Sexual arousal and orgasm increase the number of white blood cells in the body, making it easier to fight infection and illness.

  • Achieving orgasm through masturbation provides a rush of feel-good hormones (such as dopamine, serotonin and oxytocin) and can re-balance our levels of cortisol (a stress-inducing hormone). This helps our immune system function at a higher level.
  • The surge in "feel-good" hormones also promotes a more relaxed and calm state of being, making it easier to achieve restful sleep, which is a critical part in maintaining a high-functioning immune system.
  • Just as bad habits can slow your immune system, positive habits (such as a healthy sleep schedule and active sex life) can help boost your immune system which can prevent you from becoming sick.

The biology of aliens: How much do we know?

Hollywood has created an idea of aliens that doesn't match the science.

  • Ask someone what they think aliens look like and you'll probably get a description heavily informed by films and pop culture. The existence of life beyond our planet has yet to be confirmed, but there are clues as to the biology of extraterrestrials in science.
  • "Don't give them claws," says biologist E.O. Wilson. "Claws are for carnivores and you've got to be an omnivore to be an E.T. There just isn't enough energy available in the next trophic level down to maintain big populations and stable populations that can evolve civilization."
  • In this compilation, Wilson, theoretical physicist Michio Kaku, Bill Nye, and evolutionary biologist Jonathan B. Losos explain why aliens don't look like us and why Hollywood depictions are mostly inaccurate.
