“For 12 years I’ve been trying to get back my feet. Now I have learned how to walk normal, natural.”

A paralyzed man is walking again thanks to a “digital bridge” researchers created between his brain and a spinal stimulator.

“For 12 years I’ve been trying to get back my feet,” the 40-year-old Dutch man, Gert-Jan Oskam, told reporters on May 23. “Now I have learned how to walk normal, natural.”

Because of their differences from standard electrons, Dirac electrons are expected to add unprecedented electronic properties to materials. For example, they could be applied to electronic devices to perform computation and communication with extraordinary efficiency and low energy consumption.

To develop such technology, scientists must first understand the net properties and effects of Dirac electrons. But they generally coexist with standard electrons in materials, which prevents unambiguous observation and measurement.

In a recent study published in Materials Advances, Ryuhei Naito and colleagues discovered a method enabling selective observation of the Dirac electrons in materials. Using electron spin resonance, to directly observe unpaired electrons in materials to distinguish differences in character, the research group established a method to determine their scope of action in the materials and their energies.

Electrical engineers at Duke University have determined the theoretical fundamental limit for how much electromagnetic energy a transparent material with a given thickness can absorb. The finding will help engineers optimize devices designed to block certain frequencies of radiation while allowing others to pass through, for applications such as stealth or wireless communications.

Globally, the number of people living with, or dying from, neurological conditions such as stroke, Alzheimer’s disease and other dementias, and meningitis has risen substantially over the past 30 years due to the growth and aging of the global population as well as increased exposure to environmental, metabolic, and lifestyle risk factors. In 2021, 3.4 billion people experienced a nervous system condition, according to a major new analysis from the Global Burden of Disease, Injuries, and Risk Factors Study (GBD) 2021, published in The Lancet Neurology.

The analysis suggests that worldwide, the overall amount of disability, illness, and premature death —a measurement known as disability-adjusted life years (DALYs)—caused by neurological conditions increased by 18% over the past 31 years, rising from around 375 million years of healthy life lost in 1990 to 443 million years in 2021.

The absolute number of DALYs is increasing in large part due to aging and growing populations worldwide.

Set to go open-source in the coming weeks, Daniel Beauchamp’s latest setup allows you to freshen up your 3D modeling workflow.

Cerebras’ Wafer Scale Engine 3 (WSE-3) chip contains four trillion transistors and will power the 8-exaFLOP Condor Galaxy 3 supercomputer one day.

An engineer with the Deep Space Network figured out a way to decode a mysterious “new signal” coming from NASA’s Voyager 1 spacecraft.

Following the announcement of its partnership with OpenAI, tech startup Figure has released a new clip of its humanoid robot, dubbed Figure 1, chatting with an engineer as it puts away the dishes.

And we can’t tell if we’re impressed — or terrified.
