Football Helmet Smartfoam to Measure Severity of Head Injuries

As football-related concussions have been top of mind in recent years, a team of American researchers has developed and tested a nano composite smartfoam that can be placed inside a football helmet (and pads) to more accurately test the impact and power of hits.

Developed by a research team from Brigham Young University in the state of Utah, the foam measures the impact of a hit via electrical signals. The data is collected in real time and sent wirelessly to the tablet of a coach or trainer on the sidelines. A coach can know within seconds how hard a player has been hit and whether or not they should be concerned about a concussion.

When the player has a concussion, the foam compresses, and nickel nano-particles rub against the foam, creating a static electric charge. That charge is then collected through a conductive electrode in the foam measured by a microcomputer, and transmitted to a computer or smart device.

The Science Daily website reported Jake Merrell, a mechanical engineering Ph.D. student at Brigham Young University, saying that: “The standard measurement systems on the market today directly measure the acceleration, but just measuring the acceleration is not enough and can even be wrong,” “Our X-Onano smart foam sensors measure much more than just acceleration, which we see as a vital key to better diagnose head injuries,” he added.

The foam, which replaces the standard helmet foam, measures a composite of acceleration, impact energy and impact velocity to determine impact severity and location of impact, all with 90% accuracy, according to Merrell.

Australia Bans YouTube Accounts for Children Under 16 in Reversal of Previous Stance

The Australian government announced YouTube will be among the social media platforms that must ensure account holders are at least 16-years-old from December, reversing a position taken months ago on the popular video-sharing service.

YouTube was listed as an exemption in November last year when the Parliament passed world-first laws that will ban Australian children younger than 16 from platforms including Facebook, Instagram, Snapchat, TikTok and X.

Communications Minister Anika Wells released rules Wednesday that decide which online services are defined as “age-restricted social media platforms” and which avoid the age limit.

The age restrictions take effect Dec. 10 and platforms will face fines of up to 50 million Australian dollars ($33 million) for “failing to take responsible steps” to exclude underage account holders, a government statement said. The steps are not defined.

Wells defended applying the restrictions to YouTube and said the government would not be intimidated by threats of legal action from the platform’s US owner, Alphabet Inc.

“The evidence cannot be ignored that four out of 10 Australian kids report that their most recent harm was on YouTube,” Wells told reporters, referring to government research. “We will not be intimidated by legal threats when this is a genuine fight for the wellbeing of Australian kids.”

Children will be able to access YouTube but will not be allowed to have their own YouTube accounts.

YouTube said the government’s decision “reverses a clear, public commitment to exclude YouTube from this ban.”

“We share the government’s goal of addressing and reducing online harms. Our position remains clear: YouTube is a video sharing platform with a library of free, high-quality content, increasingly viewed on TV screens. It’s not social media,” a YouTube statement said, noting it will consider next steps and engage with the government.

Prime Minister Anthony Albanese said Australia would campaign at a United Nations forum in New York in September for international support for banning children from social media.

“I know from the discussions I’ve had with other leaders that they are looking at this and they are considering what impact social media is having on young people in their respective nations,” Albanese said. “It is a common experience. This is not an Australian experience."

Last year, the government commissioned an evaluation of age assurance technologies that was to report last month on how young children could be excluded from social media.

The government had yet to receive that evaluation’s final recommendations, Wells said. But she added the platform users won’t have to upload documents such as passports and driver’s licenses to prove their age.

“Platforms have to provide an alternative to providing your own personal identification documents to satisfy themselves of age,” Wells said. “These platforms know with deadly accuracy who we are, what we do and when we do it. And they know that you’ve had a Facebook account since 2009, so they know that you are over 16."

Exempt services include online gaming, messaging, education and health apps. They are excluded because they are considered less harmful to children.

The minimum age is intended to address harmful impacts on children including addictive behaviors caused by persuasive or manipulative platform design features, social isolation, sleep interference, poor mental and physical health, low life-satisfaction and exposure to inappropriate and harmful content, government documents say.
