After 25 people used virtual reality headsets to practice flying with virtual wings—flapping their arms—their visual cortex responded to the wings almost as if they were real arms, treating them as body parts.

Mind-controlled bionic arms use nerve implants to restore sensation and movement

Unlike traditional prosthetics that rely on surface electrodes or mechanical parts, this system uses implanted titanium and nerve-connected electrodes to enable a seamless brain-to-arm connection. Patients train in virtual reality with their implanted signals before using the physical prosthesis.

Is using VR as a tool to enhance empathy ethical?

This research paper explores whether virtual reality should be used as a tool for improving our moral character — and, if not, what ethical alternatives could be.

A 1992 failed parachute test provided the hardware for the first mixed reality system

The Virtual Fixtures platform was developed to improve human dexterity by merging physical and virtual objects with haptic feedback from an upper-body exoskeleton. Tight budgeting and significant equipment needs nearly canceled the project, were it not for salvaging and repairing cameras and sensors from a smashed experimental parachute rig.

AI systems identify patterns involving physics and time through 'world models'

These realistic virtual environments, such as driving simulations seen in video games, allow these systems to "learn" properties about reality beyond what can be captured in samples of text, images, and videos. Training AI in these simulated environments can help develop "physical AI" for automated robotic systems. (Some readers may experience a paywall.)

The aviation industry built trust in automation by keeping pilots in the cockpit

Nearly 70% of Americans feel uncomfortable riding in a driverless car, and 81% of them would not fly on a pilotless plane. However, automated systems on planes were slowly introduced and advertised as enhancing safety—an approach that may benefit driverless vehicles.

The dreaming brain, as understood by scientists

Technology has advanced to where the seemingly separate fields of psychology and neuroscience are asking the same questions about dreams, such as whether they're more closely related to perception or visualization. Some field-intersecting findings include research that shows people with impaired face perception don't dream of faces, those with brain legion-related cognition difficulties deal with similar issues in dreams, and children's dreams change in parallel to their cognitive development.

The pair began their aviation research by studying the 'mechanics' of birds

Taking inspiration from gliding pioneer Otto Lilienthal—whose gliders resembled the wings of birds—Wilbur took to observing birds to understand how they do it, in order to solve the problem of flight. This opening episode on the brothers explores their lives and accomplishments.

Blindfolded people could identify objects by touch alone a week after encountering them

These touch memories are more complex and durable than previously thought. In research published in 2018, blindfolded volunteers touched over 150 household objects for about 10 seconds each, and afterward correctly identified the objects more than 90 percent of the time when presented with the object and a similar one. Participants still knew most of the objects a week later with about 85 percent accuracy. (Some users may experience a paywall.)

University of Virginia has the nation's premier near-death studies department

Researcher Bruce Greyson has been studying this phenomenon at the University of Virginia for decades, where he now directs the Division of Perceptual Studies. This piece from the university’s magazine explores the breadth and substance of the department, founded by pioneer researcher Ian Stevenson.

SpaceX's Crew Dragon was the first crewed spacecraft piloted by touchscreen

In May 2020, NASA astronauts flying SpaceX's Crew Dragon to the International Space Station used touchscreen controls instead of traditional switches and dials, a significant shift for astronauts and how they pilot and interact with spacecraft. (Some users may experience a paywall.)

Eleven deaf men played a pivotal role in America's human spaceflight program

In the mid-20th century, 11 deaf men volunteered for a series of experiments that offered unprecedented insights into the effects of weightlessness on the human body. Most of the men had become deaf in early childhood as a result of spinal meningitis, a condition known to damage the vestibular system and make them less susceptible to motion sickness. For a decade, these men participated in extreme motion sickness situations, including living in a slowly spinning room, spending time in centrifuge pods designed to simulate hypergravity, and flying in parabolic flights sometimes referred to as the "Vomit Comet."

The brains of people who experience frisson have unique neural pathways

A small 2016 study aimed to investigate the behavioral and neural differences between 10 individuals who experience goose bumps when listening to music and 10 who typically don’t. Scientists reported that individuals experiencing musical chills had greater white matter connectivity in specific auditory, emotional, and social processing areas of the brain.

Some animals may anchor their brain cells to specific landmarks to determine direction

In a study of bats exploring a new area, specific sets of "head direction cells" were seen becoming active based on bats' orientation when moving, and this activity became more coordinated over time. Researchers suspect, like humans, bats and other animals establish this sense of direction based on movement relative to known points of interest.

Coined by space philosopher Frank White in 1987, the term refers to the paradigm-shifting experience a person undergoes upon viewing Earth from space. Commercial spaceflights aim to bring this perspective to a broader audience, inspiring changes in behavior and worldview among participants.

Some claim breathwork can improve mental health, help process trauma, and more

Research shows people who practice breathing exercises see a decrease in depression and stress levels, and that such exercises are about as effective at treating PTSD as conventional approaches. Even something as simple as extending exhales can slow one's heart rate and activate the parasympathetic nervous system.

Fruit fly experiments helped identify genes responsible for major body development

The insects' fast life cycle and affordability have allowed geneticists to quickly identify which genes are responsible for limbs, eyes, and other body structures by inducing mutations. The same genes may be responsible for different parts of a species' body, such as limb-building genes being responsible for wing pigmentation in butterflies.
