wearable devices

I’ve got some exciting news to share with you: as of May 6, 2018, NIH’s All of Us Research Program is open to everyone living in the United States, age 18 and older. That means that you, along with your family and friends, can join with 1 million or more Americans from all walks of life to create an unprecedented research resource that will speed biomedical breakthroughs and transform medicine.

To launch this historic undertaking, All of Us yesterday held community events at seven sites across the nation, from Alabama to Washington state. I took part in an inspiring gathering at the Abyssinian Baptist Church in New York’s Harlem neighborhood, where I listened to community members talk about how important it is for everyone to be able to take part in this research. I shared information on how All of Us will help researchers devise new ways of improving the health of everyone in this great nation.

In recent years, researchers fueled by the BRAIN Initiative and many other NIH-supported efforts have made remarkable progress in mapping the human brain in all its amazing complexity. Now, a powerful new imaging technology promises to further transform our understanding [1]. This wearable scanner, for the first time, enables researchers to track neural activity in people in real-time as they do ordinary things—be it drinking tea, typing on a keyboard, talking to a friend, or even playing paddle ball.

This new so-called magnetoencephalography (MEG) brain scanner, which looks like a futuristic cross between a helmet and a hockey mask, is equipped with specialized “quantum” sensors. When placed directly on the scalp surface, these new MEG scanners can detect weak magnetic fields generated by electrical activity in the brain. While current brain scanners weigh in at nearly 1,000 pounds and require people to come to a special facility and remain absolutely still, the new system weighs less than 2 pounds and is capable of generating 3D images even when a person is making motions.

I want to wish everyone a Happy New Year! Hope your 2018 is off to a great start.

Over the holidays, the journal Science published its annual, end-of-the-year list of research breakthroughs, from anthropology to zoology. I always look forward to seeing the list and reflecting on some of the stunning advances reported in the past 12 months. Last year was no exception. Science’s 2017 Breakthrough of the Year, as chosen by its editors, was in the field of astrophysics. Scientists were able to witness the effects of the collision of two neutron stars—large stars with collapsed inner cores—smacking into each other 130 million light years away. How cool is that!

Numbered prominently among the nine other breakthroughs were five from biomedicine: gene therapy, gene editing, cancer immunotherapy, cryo-EM, and biology preprints. All involved varying degrees of NIH support, and all drew great interest from readers. In fact, three of the top four vote-getters in the “People’s Choice” category came from biomedicine. That includes the People’s 2017 Breakthrough of the Year: gene therapy success. And so, in what has become a Director’s Blog tradition, I’ll kick off our new year of posts by taking a closer look at these biomedical breakthroughs—starting with the little girl in the collage above, and moving clockwise around the images:

Millions of Americans now head out the door each day wearing devices that count their steps, check their heart rates, and help them stay fit in general. But with further research, these “wearables” could also play an important role in the early detection of serious medical conditions. In partnership with health-care professionals, people may well use the next generation of wearables to monitor vital signs, blood oxygen levels, and a wide variety of other measures of personal health, allowing them to see in real time when something isn’t normal and, if unusual enough, to have it checked out right away.

In the latest issue of the journal PLoS Biology [1], an NIH-supported study offers an exciting glimpse of this future. Wearing a commercially available smartwatch over many months, more than 40 adults produced a continuous daily stream of accurate personal health data that researchers could access and monitor. When combined with standard laboratory blood tests, these data—totaling more than 250,000 bodily measurements a day per person—can detect early infections through changes in heart rate.
