British scientists have developed a lightweight and highly sensitive brain imaging device that can be worn as a helmet, allowing the patient to move about naturally.

Results from tests of the scanner showed that patients were able to stretch, nod and even drink tea or play table tennis while their brain activity was being recorded, millisecond by millisecond, by the magnetoencephalography (MEG) system.

Researchers who developed the device and published their results in the journal Nature said they hoped the new scanner would improve research and treatment for patients who can’t use traditional fixed MEG scanners, such as children with epilepsy, babies, or patients with disorders like Parkinson’s disease.

“This has the potential to revolutionize the brain imaging field, and transform the scientific and clinical questions that can be addressed with human brain imaging,” said Gareth Barnes, a professor at the Wellcome Trust Centre for Human Neuroimaging at University College London, who co-led the work.

Current MEG scanners are cumbersome and weigh as much as half a ton, partly because the sensors they use to measure the brain’s magnetic field need to be kept very cold - at minus 269 degrees Celsius, Barnes’ team explained.

They also run into difficulties when patients are unable to stay very still - very young children or patients with movement disorders for example - since even a 5-millimeter movement can mean the images are unusable.

In the helmet scanner, the researchers overcame these problems by using quantum sensors, which are lightweight, work at room temperature and can be placed directly onto scalp - increasing the amount of signal they are able to pick up.

Matt Brookes, who worked with Barnes and built the prototype at Nottingham University, said that as well as overcoming the challenge of some patients being unable to stay still, the wearable scanner offers new possibilities in measuring peoples’ brain function during real-world tasks and social interactions.

“This has significant potential for impact on our understanding of not only healthy brain function but also on a range of neurological, neurodegenerative and mental health conditions.”

The US-China tech war is all but certain to heat up no matter whether Republican Donald Trump or Vice President Kamala Harris wins the Nov. 5 US presidential election, with the Democrat likely to come out with targeted new rules and Trump a blunter approach.

New efforts to slow the flow of less-sophisticated Chinese chips, smart cars and other imports into the US are expected, alongside more curbs on chipmaking tools and highly-prized AI chips headed to China, according to former officials from the Biden and Trump administrations, industry experts and people close to the campaigns, according to Reuters.

In her bid for the US presidency, Democrat Harris has said she will make sure "America, not China, wins the competition for the 21st century," while Republican candidate Trump has pitched ever-increasing tariffs as a cure-all that includes combating Chinese technological advancement.

In short, the battle to keep US money and technology from boosting China's military and artificial intelligence capabilities is bound to escalate under either Harris or Trump.

"We're seeing the opening of a new front on the US China tech cold war that is focused on data, software and connected devices," said Peter Harrell, a former national security official in the Biden administration.

Last month, the US proposed rules to keep connected cars made with Chinese components off America's streets, while a law was passed this spring that said the short video app TikTok must be sold by its Chinese parent by next year or be banned.

“There’s a lot of concern if a Chinese company is able to access and provide updates to devices,” Harrell said. “The connected car thing and TikTok are just the tip of the iceberg.”

Should Harris win the election, her approach would likely be more targeted and coordinated than Trump’s, people close to both administrations say.

For example, she is likely to continue working with allies much like the Biden administration has, to keep US tech from aiding the Chinese military, Harrell said.

A Trump administration, on the other hand, may move more quickly, and be more willing to punish recalcitrant allies.

"I think we learned from President Trump's first term that he has a bias for action," said Jamieson Greer, former chief of staff to Robert Lighthizer, the US trade representative under Trump who remains close to the campaign.

Nazak Nikakhtar, a Commerce Department official under Trump who knows his current advisors, expects a Trump administration to be "much more aggressive about export control policies towards China."

She anticipates "a significant expansion of the entity list," to capture affiliates and business partners of listed companies. The list restricts exports to those on it. Trump added China's Huawei Technologies to the list for sanctions busting.

Licenses to ship US technology to China also are more likely to be denied, Nikakhtar said.

She said she would not be surprised if a Trump administration imposed restrictions not only on imports of Chinese chips but on "certain products containing those chips."

And she expects Trump to be tougher than Harris on allies who don't follow the US lead. "The Trump philosophy is more of a stick," she said.

Bill Reinsch, a former Commerce official during the Clinton administration sees Trump as likely to take a "sledgehammer" to controls where Harris would use a "scalpel."

"Trump's approach has been across-the-board, most clearly seen in his current tariff proposals," Reinsch said.

Trump has said he would impose tariffs of 10 or 20 percent on all imports (not just Chinese) and 60 percent or more on Chinese imports.

Harris has described Trump's tariff plan as a tax on consumers, but the Biden administration has seen the need for targeted tariffs including increasing the rate on semiconductors from 25 percent to 50 percent by 2025.

China has repeatedly said it would safeguard its rights and interests. Last year, it targeted US memory chip maker Micron Technology after Washington imposed a series of export controls on US chips and chipmaking equipment, and the US accused Beijing of penalizing other US companies amid growing tensions.

China also introduced export restrictions last year on germanium and gallium, metals widely used in chipmaking, citing national security interests. It issued new curbs on some graphite products that go into electric vehicle batteries in October 2023, days after the US tightened rules on chip-related exports. And in June it unveiled new rules on rare earth elements critical for military equipment and consumer electronics.

Wilbur Ross, commerce secretary under Trump, said that the US needs to be tough on China, but strategic, too, noting the US is still dependent on China for rare earths.

"It would be very dangerous to just try to cut them off," he said.
