A first-of-its-kind flexible sensor turns a pair of earbuds into a device capable of recording brain activity and analyzing sweat, making them useful for diagnosing diseases and health monitoring.

The background: Health monitoring wearables can measure our blood pressure, track our heart rates, and even detect infections before we start to feel sick, helping us take better care of ourselves and potentially even giving us a way to prevent the spread of diseases.

The devices are useless if no one wants to wear them, though, so finding designs that are comfortable and easy to integrate into daily life is key. Because earbuds are already popular, researchers have used them as the basis for health monitoring devices that record brain activity to predict strokes, epileptic seizures, or Parkinson’s disease.

Epilepsy is a neurological condition that causes people to have recurring seizures. Epileptic seizures may be mild and barely noticeable or stronger ones, causing severe muscle spasms or loss of consciousness. These may last a few seconds or several minutes. Anyone can develop epilepsy at any point in their life.

Ray Kurzweil is an inventor, thinker, and futurist famous for forecasting the pace of technology and predicting the world of tomorrow. In this video, Kurzweil suggests the blueprint for the master algorithm—or a single, general purpose learning algorithm—is hidden in the brain.

The brain, according to Kurzweil, consists of repeating modules that self-organize into hierarchies that build simple patterns into complex concepts. We don’t have a complete understanding of how this process works yet, but Kurzweil believes that as we study the brain more and reverse engineer what we find, we’ll learn to write the master algorithm.

Mental phenomena influence the material world.

The human mind does not like to make mistakes—and makes time to avoid repeating them. A new study from University of Iowa researchers shows how the human brain, in just one second, can distinguish between an outcome caused by human error and one in which the person is not directly to blame.

Moreover, the researchers found that in cases of human error, the brain takes additional time to catalog the error and inform the rest of the body about it to avoid repeating the mistake.

“The novel aspect about this study is the brain can very quickly distinguish whether an undesirable outcome is due to a (human) error, or due to something else,” says Jan Wessel, professor in the Department of Psychological and Brain Sciences at Iowa and the study’s corresponding author. “If the brain realizes an error was the cause, it will then start additional processes to avoid further errors, which it won’t do if the outcome wasn’t due to its own action.”

Elon Musk’s Neuralink is looking for a volunteer for its first clinical trial of a brain implant chip. The trial, which begins next year, has attracted thousands of prospective patients. The ideal candidate must be an adult under 40 with all four limbs paralyzed. The procedure involves inserting electrodes and wires into the brain, with a small computer replacing part of the skull. The computer will collect and analyze brain activity, sending the data wirelessly to a nearby device. Neuralink aims to translate thoughts into computer commands. However, the company has faced criticism for animal testing practices.

The FDA approved human trials after initially rejecting them in 2022, citing safety concerns.

The FDA had initially rejected the company’s request to run human trials back in 2022, citing safety concerns.

The hope is that people who are unable to speak because of neurological conditions may one day be able to communicate again thanks to this modern technology.

Helping people with motor disorders

“There are many patients who suffer from debilitating motor disorders, like ALS (amyotrophic lateral sclerosis) or locked-in syndrome, that can impair their ability to speak,” said Gregory Cogan, Ph.D., a professor of neurology at Duke University’s School of Medicine and one of the lead researchers involved in the project.

Summary: A new study reveals insights into how general anesthesia affects consciousness and sensory perception.

Using animal models, researchers found that while propofol anesthesia allows sensory information to reach the brain, it disrupts the spread of signals across the cortex. This suggests that consciousness requires synchronized communication throughout the brain, and propofol’s effect of limiting this interconnectivity could explain its role in inducing unconsciousness.
