This Brain Doc Has a “Repulsive” Idea to Make Football Safer
What do football superstars Tom Brady, Drew Brees, Philip Rivers, and Adrian Peterson all have in common? Last year they wore helmets that provided the poorest protection against concussions in all the NFL.
"You're only as protected as well as the worst helmet that's out there."
A Dangerous Policy
Football helmets are rated on a one-star to five-star system based on how well they do the job of protecting the player. The league has allowed players to use their favorites, regardless of the star rating.
The Oxford-trained neuroscientist Ray Colello conducted a serious analysis of just how much the protection can vary between each level of star rating. Colello and his team of graduate students sifted through two seasons of game video to identify which players were wearing what helmets. There was "a really good correlation with position, but the correlation is much more significant based on age."
"The average player in the NFL is 26.6 years old, but the average age of a player wearing a one-star helmet is 34. And for anyone who knows football, that's ancient," the brain doc says. "Then for our two-star helmet, it's 32; and for a three-star helmet it's 29." Players were sticking with the helmets they were familiar with in college, despite the fact that equipment had improved considerably in recent years.
"You're only as protected as well as the worst helmet that's out there," Colello explains. Offering an auto analogy, he says, "It's like, if you run into the back of a Pinto, even if you are in a five-star Mercedes, that gas tank may still explode and you are still going to die."
It's one thing for a player to take a risk at scrambling his own brain; it's another matter to put a teammate or opponent at needless risk. Colello published his analysis early last year and the NFL moved quickly to ban the worst performing helmets, starting next season.
Some of the 14 players using the soon-to-be-banned helmets, like Drew Brees and Philip Rivers, made the switch to a five-star helmet at the start of training camp and stayed with it. Adrian Peterson wore a one-star helmet throughout the season.
Tom Brady tried but just couldn't get comfortable with a new bonnet and, after losing a few games, switched back to his old one in the middle of the season; he says he's going to ask the league to "grandfather in" his old helmet so he can continue to use it.
As for Colello, he's only just getting started. The brain doc has a much bigger vision for the future of football safety. He wants to prevent concussions from even occurring in the first place by creating an innovative new helmet that's unlike anything the league has ever seen.

"A Force Field" of Protection
His inspiration was serendipitous; he was at home watching a football game on TV when Denver Bronco's receiver Wes Welker was hit, lay flat on the field with a concussion, and was carted off. As a commercial flickered on the screen, he ambled into the kitchen for another beer. "What those guys need is a force field protecting them," he thought to himself.
Like so many households, the refrigerator door was festooned with magnets holding his kids' school work in place. And in that eureka moment the idea popped into his head: "Maybe the repulsive force of magnets can put a break on an impact before it even occurs." Colello has spent the last few years trying to turn his concept into reality.
Newton's laws of physics – mass and speed – play out graphically in a concussion. The sudden stop of a helmet-to-helmet collision can shake the brain back and forth inside the skull like beans in a maraca. Dried beans stand up to the impact, making their distinctive musical sound; living brain tissue is much softer and not nearly so percussive. The resulting damage is a concussion.
The risk of that occurring is greater than you might think. Researchers using accelerometers inside helmets have determined that a typical college football player experiences about 600 helmet-to-helmet contacts during a season of practice and games. Each hit generates a split second peak g-force of 20 to 150 within the helmet and the odds of one causing a concussion increase sharply over 100 gs of force.
By comparison, astronauts typically experience a maximum sustained 3gs during lift off and most humans will black out around 9gs, which is why fighter pilots wear special pressure suits to counter the effects.
"It stretches the time line of impact quite dramatically. In fact in most instances, it doesn't even hit."
The NFL's fastest player, Chris Johnson, can run 19.3 mph. A collision at that speed "produces 120gs worth of force," Colello explains. "But if you can extend that time of impact by just 5 milliseconds (from 12 to 17msec) you'll shift that g-force down to 84. There is a very good chance that he won't suffer a concussion."
The neuroscientist dived into learning all he could about the physics magnets. It turns out that the most powerful commercially available magnet is an alloy made of neodymium, iron, and boron. The elements can be mixed and glued together in any shape and then an electric current is run through to make it magnetic; the direction of the current establishes the north-south poles.
A 1-pound neodymium magnet can repulse 600 times its own weight, even though the magnetic field extends less than an inch. That means it can push back a magnet inside another helmet but not affect the brain.
Crash Testing the Magnets
Colello couldn't wait to see if his idea panned out. With blessing from his wife to use their credit card, he purchased some neodymium magnets and jury-rigged experiments at home.
The reinforced plastics used in football helmets don't affect the magnetic field. And the small magnets stopped weights on gym equipment that were dropped from various heights. "It stretches the time line of impact quite dramatically. In fact in most instances, it doesn't even hit," says Colello. "We are dramatically shifting the curve" of impact.
Virginia Commonwealth University stepped in with a $50,000 innovation grant to support the next research steps. The professor ordered magnets custom-designed to fit the curvature of space inside the front and sides of existing football helmets. That makes it impossible to install them the wrong way, and ensures the magnets' poles will always repel and not attract. It adds about a pound and a half to the weight of the helmet.

Colello rented crash test dummy heads crammed with accelerometers and found that the magnets performed equally well at slowing collisions when fixed to a pendulum in a test that approximated a helmet and head hitting a similarly equipped helmet. It impressively reduced the force of contact.
The NFL was looking for outside-the-box thinking to prevent concussions. It was intrigued by Colello's approach and two years ago invited him to submit materials for review. To be fair to all entrants, the league proposed to subject all entries to the same standard crush test to see how well each performed in lessening impact. The only trouble was, Colello's approach was designed to avoid collisions, not lessen their impact. The test wouldn't have been a valid evaluation and he withdrew from consideration.
But Colello's work caught the attention of Stefan Duma, an engineering professor at Virginia Tech who developed the five-star rating system for football helmets.
"In theory it makes sense to use [the magnets] to slow down or reduce acceleration, that's logical," says Duma. He believes current helmet technology is nearing "the end of the physics barrier; you can only absorb so much energy in so much space," so the field is ripe for new approaches to improve helmet technology.
However, one of Duma's concerns is whether magnets "are feasible from a weight standpoint." Most helmets today weigh between two and four pounds, and a sufficiently powerful magnet might add too much weight. One possibility is using an electromagnet, which potentially could be lighter and more powerful, particularly if the power supply could be carried lower in the body, say in the shoulder pads.
Colello says his lab tests are promising enough that the concept needs to be tried out on the playing field. "We need to make enough helmets for two teams to play each other in a regulation-style game and measure the impact forces that are generated on each, and see if there is a significant reduction." He is waiting to hear from the National Institutes of Health on a grant proposal to take that next step toward dramatically reducing the risk of concussions in the NFL.
Just five milliseconds could do it.
New tech aims to make the ocean healthier for marine life
A defunct drydock basin arched by a rusting 19th century steel bridge seems an incongruous place to conduct state-of-the-art climate science. But this placid and protected sliver of water connecting Brooklyn’s Navy Yard to the East River was just right for Garrett Boudinot to float a small dock topped with water carbon-sensing gear. And while his system right now looks like a trio of plastic boxes wired up together, it aims to mediate the growing ocean acidification problem, caused by overabundance of dissolved carbon dioxide.
Boudinot, a biogeochemist and founder of a carbon-management startup called Vycarb, is honing his method for measuring CO2 levels in water, as well as (at least temporarily) correcting their negative effects. It’s a challenge that’s been occupying numerous climate scientists as the ocean heats up, and as states like New York recognize that reducing emissions won’t be enough to reach their climate goals; they’ll have to figure out how to remove carbon, too.
To date, though, methods for measuring CO2 in water at scale have been either intensely expensive, requiring fancy sensors that pump CO2 through membranes; or prohibitively complicated, involving a series of lab-based analyses. And that’s led to a bottleneck in efforts to remove carbon as well.
But recently, Boudinot cracked part of the code for measurement and mitigation, at least on a small scale. While the rest of the industry sorts out larger intricacies like getting ocean carbon markets up and running and driving carbon removal at billion-ton scale in centralized infrastructure, his decentralized method could have important, more immediate implications.
Specifically, for shellfish hatcheries, which grow seafood for human consumption and for coastal restoration projects. Some of these incubators for oysters and clams and scallops are already feeling the negative effects of excess carbon in water, and Vycarb’s tech could improve outcomes for the larval- and juvenile-stage mollusks they’re raising. “We’re learning from these folks about what their needs are, so that we’re developing our system as a solution that’s relevant,” Boudinot says.
Ocean acidification can wreak havoc on developing shellfish, inhibiting their shells from growing and leading to mass die-offs.
Ocean waters naturally absorb CO2 gas from the atmosphere. When CO2 accumulates faster than nature can dissipate it, it reacts with H2O molecules, forming carbonic acid, H2CO3, which makes the water column more acidic. On the West Coast, acidification occurs when deep, carbon dioxide-rich waters upwell onto the coast. This can wreak havoc on developing shellfish, inhibiting their shells from growing and leading to mass die-offs; this happened, disastrously, at Pacific Northwest oyster hatcheries in 2007.
This type of acidification will eventually come for the East Coast, too, says Ryan Wallace, assistant professor and graduate director of environmental studies and sciences at Long Island’s Adelphi University, who studies acidification. But at the moment, East Coast acidification has other sources: agricultural runoff, usually in the form of nitrogen, and human and animal waste entering coastal areas. These excess nutrient loads cause algae to grow, which isn’t a problem in and of itself, Wallace says; but when algae die, they’re consumed by bacteria, whose respiration in turn bumps up CO2 levels in water.
“Unfortunately, this is occurring at the bottom [of the water column], where shellfish organisms live and grow,” Wallace says. Acidification on the East Coast is minutely localized, occurring closest to where nutrients are being released, as well as seasonally; at least one local shellfish farm, on Fishers Island in the Long Island Sound, has contended with its effects.

Besides CO2, ocean water contains two other forms of dissolved carbon — carbonate (CO3-) and bicarbonate (HCO3) — at all times, at differing levels. At low pH (acidic), CO2 prevails; at medium pH, HCO3 is the dominant form; at higher pH, CO3 dominates. Boudinot’s invention is the first real-time measurement for all three, he says. From the dock at the Navy Yard, his pilot system uses carefully calibrated but low-cost sensors to gauge the water’s pH and its corresponding levels of CO2. When it detects elevated levels of the greenhouse gas, the system mitigates it on the spot. It does this by adding a bicarbonate powder that’s a byproduct of agricultural limestone mining in nearby Pennsylvania. Because the bicarbonate powder is alkaline, it increases the water pH and reduces the acidity. “We drive a chemical reaction to increase the pH to convert greenhouse gas- and acid-causing CO2 into bicarbonate, which is HCO3,” Boudinot says. “And HCO3 is what shellfish and fish and lots of marine life prefers over CO2.”
This de-acidifying “buffering” is something shellfish operations already do to water, usually by adding soda ash (NaHCO3), which is also alkaline. Some hatcheries add soda ash constantly, just in case; some wait till acidification causes significant problems. Generally, for an overly busy shellfish farmer to detect acidification takes time and effort. “We’re out there daily, taking a look at the pH and figuring out how much we need to dose it,” explains John “Barley” Dunne, director of the East Hampton Shellfish Hatchery on Long Island. “If this is an automatic system…that would be much less labor intensive — one less thing to monitor when we have so many other things we need to monitor.”
Across the Sound at the hatchery he runs, Dunne annually produces 30 million hard clams, 6 million oysters, and “if we’re lucky, some years we get a million bay scallops,” he says. These mollusks are destined for restoration projects around the town of East Hampton, where they’ll create habitat, filter water, and protect the coastline from sea level rise and storm surge. So far, Dunne’s hatchery has largely escaped the ill effects of acidification, although his bay scallops are having a finicky year and he’s checking to see if acidification might be part of the problem. But “I think it's important to have these solutions ready-at-hand for when the time comes,” he says. That’s why he’s hosting a second, 70-liter Vycarb pilot starting this summer on a dock adjacent to his East Hampton operation; it will amp up to a 50,000 liter-system in a few months.
If it can buffer water over a large area, absolutely this will benefit natural spawns. -- John “Barley” Dunne.
Boudinot hopes this new pilot will act as a proof of concept for hatcheries up and down the East Coast. The area from Maine to Nova Scotia is experiencing the worst of Atlantic acidification, due in part to increased Arctic meltwater combining with Gulf of St. Lawrence freshwater; that decreases saturation of calcium carbonate, making the water more acidic. Boudinot says his system should work to adjust low pH regardless of the cause or locale. The East Hampton system will eventually test and buffer-as-necessary the water that Dunne pumps from the Sound into 100-gallon land-based tanks where larvae grow for two weeks before being transferred to an in-Sound nursery to plump up.
Dunne says this could have positive effects — not only on his hatchery but on wild shellfish populations, too, reducing at least one stressor their larvae experience (others include increasing water temperatures and decreased oxygen levels). “If it can buffer water over a large area, absolutely this will [benefit] natural spawns,” he says.
No one believes the Vycarb model — even if it proves capable of functioning at much greater scale — is the sole solution to acidification in the ocean. Wallace says new water treatment plants in New York City, which reduce nitrogen released into coastal waters, are an important part of the equation. And “certainly, some green infrastructure would help,” says Boudinot, like restoring coastal and tidal wetlands to help filter nutrient runoff.
In the meantime, Boudinot continues to collect data in advance of amping up his own operations. Still unknown is the effect of releasing huge amounts of alkalinity into the ocean. Boudinot says a pH of 9 or higher can be too harsh for marine life, plus it can also trigger a release of CO2 from the water back into the atmosphere. For a third pilot, on Governor’s Island in New York Harbor, Vycarb will install yet another system from which Boudinot’s team will frequently sample to analyze some of those and other impacts. “Let's really make sure that we know what the results are,” he says. “Let's have data to show, because in this carbon world, things behave very differently out in the real world versus on paper.”
When Erika Schreder’s 14-year-old daughter, who is Black, had her curly hair braided at a Seattle-area salon two or three times recently, the hairdresser applied a styling gel to seal the tresses in place.
Schreder and her daughter had been trying to avoid harmful chemicals, so they were shocked to later learn that this particular gel had the highest level of formaldehyde of any product tested by the Washington State Departments of Ecology and Health. In January 2023, the agencies released a report that uncovered high levels of formaldehyde in certain hair products, creams and lotions marketed to or used by people of color. When Schreder saw the report, she mentioned it to her daughter, who told her the name of the gel smoothed on her hair.
“It was really upsetting,” said Schreder, science director at Toxic-Free Future, a Seattle-based nonprofit environmental health research and advocacy organization. “Learning that this product used on my daughter’s hair contained cancer-causing formaldehyde made me even more committed to advocating for our state to ban toxic ingredients in cosmetics and personal care products.”
In 2013, Toxic-Free Future launched Mind the Store to challenge the nation’s largest retailers in adopting comprehensive policies that eliminate toxic chemicals in their personal care products and packaging, and develop safer alternatives.
Now, more efforts are underway to expose and mitigate the harm in cosmetics, hair care and other products that children apply on their faces, heads, nails and other body parts. Advocates hope to raise awareness among parents while prompting manufacturers and salon professionals to adopt safer alternatives.
A recent study by researchers at Columbia University Mailman School of Public Health and Earthjustice, a San Francisco-based nonprofit public interest environmental law organization, revealed that most children in the United States use makeup and body products that may contain carcinogens and other toxic chemicals. In January, the results were published in the International Journal of Environmental Research and Public Health. Based on more than 200 surveys, 70 percent of parents in the study reported that their children 12 or younger have used makeup and body products marketed to youth — for instance, glitter, face paint and lip gloss.
Childhood exposure to harmful makeup and body product ingredients can also be considered an environmental justice issue, as communities of color may be more likely to use these products.
“We are concerned about exposure to chemicals that may be found in cosmetics and body products, including those that are marketed toward children,” said the study’s senior author, Julie Herbstman, a professor and director of the Columbia Center for Children's Environmental Health. The goal of the survey was to try to understand how much kids are using cosmetic and body products and when, how and why they are using them.
“There is widespread use of children’s cosmetic and body products, and kids are using them principally to play,” Herbstman said. “That’s really quite different than how adults use cosmetic and body products.” Even with products that are specifically designed for children, “there’s no regulation that ensures that these products are safe for kids.” Also, she said, some children are using adult products — and they may do so in inadvisable ways, such as ingesting lipstick or applying it to other areas of the face.
Earlier research demonstrated that beauty and personal care products manufactured for children and adults frequently contain toxic chemicals, such as lead, asbestos, PFAS, phthalates and formaldehyde. Heavy metals and other toxic chemicals in children’s makeup and body products are particularly harmful to infants and youth, who are growing rapidly and whose bodies are less efficient at metabolizing these chemicals. Whether these chemicals are added intentionally or are present as contaminants, they have been associated with cancer, neurodevelopmental harm, and other serious and irreversible health effects, the Columbia University and Earthjustice researchers noted.
“Even when concentrations of individual chemicals are low in products, the potential for interactive effects from multiple toxicants is important to take into consideration,” the authors wrote in the journal article. “Allergic reactions, such as contact dermatitis, are some of the most frequently cited negative health outcomes associated with the use of cosmetics.”

In addition to children’s rapid growth rate, the study also reported that their small body size, developing tissues and organs, and immature immune systems are biologically more prone to the effects of toxicants than adults. Meanwhile, the study noted, “childhood exposure to harmful makeup and body product ingredients can also be considered an environmental justice issue, as communities of color may be more likely to use these products.”
Although adults are the typical users of cosmetics, similar items are heavily marketed to youth with attention-grabbing features such as bright colors, animals and cartoon characters, according to the study. Beyond conventional makeup such as eyeshadow and lipstick, children may apply face paint, body glitter, nail polish, hair gel and fragrances. They also may frequent social media platforms on which these products are increasingly being promoted.
Products for both children and adults are currently regulated by the U.S. Food and Drug Administration under the Federal Food, Drug, and Cosmetic Act of 1938. Also, the Fair Packaging and Labeling Act of 1967 directs the Federal Trade Commission and the FDA “to issue regulations requiring that all ‘consumer commodities’ be labeled to disclose net contents, identity of commodity, and name and place of business of the product's manufacturer, packer, or distributor.” As the Columbia University and Earthjustice authors pointed out, though, “current safety regulations have been widely criticized as inadequate.”
The Personal Care Products Council in Washington, D.C., “fundamentally disagrees with the premise that companies put toxic chemicals in products produced for children,” industry spokeswoman Lisa Powers said in an email. Founded in 1894, the national trade association represents 600 member companies that manufacture, distribute and supply most personal care products marketed in the United States.
No category of consumer products is subject to less government oversight than cosmetics and other personal care products. -- Environmental Working Group.
“Science and safety are the cornerstones of our industry,” Powers stated. For more than a decade, she wrote, “the [Council] and our member companies worked diligently with a bipartisan group of congressional leaders and a diverse group of stakeholders to enhance the effectiveness of the FDA regulatory authority and to provide the safety reassurances that consumers expect and deserve.”
Powers added that the “industry employs and consults thousands of scientific and medical experts” who study the impacts of cosmetics and personal care products and the ingredients used in them. The Council also maintains a comprehensive database where consumers can look up science and safety information on the thousands of ingredients in sunscreens, toothpaste, shampoo, moisturizer, makeup, fragrances and other products.
However, the Environmental Working Group, which empowers consumers with breakthrough research to make informed choices about healthy living, believes the regulations are still not robust enough. “No category of consumer products is subject to less government oversight than cosmetics and other personal care products,” states the organization’s website. “Although many of the chemicals and contaminants in cosmetics and personal care products likely pose little risk, exposure to some has been linked to serious health problems, including cancer.”
The group, which operates the Skin Deep Database noted that “since 2009, 595 cosmetics manufacturers have reported using 88 chemicals, in more than 73,000 products, that have been linked to cancer, birth defects or reproductive harm.”
But change, for both adults and kids, is on the horizon. The Modernization of Cosmetics Regulation Act of 2022 significantly expanded the FDA’s authority to regulate cosmetics. In May 2023, Washington state adopted a law regulating cosmetics and personal care products. The Toxic-Free Cosmetics Act (HB 1047) bans chemicals in beauty and personal care products, such as PFAS, lead, mercury, phthalates and formaldehyde-releasing agents. These bans take effect in 2025, except for formaldehyde releasers, which have a phased-in approach starting in 2026.
Industry and advocates view this as a positive development. Powers, the spokesperson, praised “the long-awaited” Modernization Cosmetics Regulation Act of 2022, which she said, “advances product safety and innovation.” Jen Lee, chief impact officer at Beautycoutner, a company that sells personal care products, also welcomes the change. “We were proud to support the Washington Toxic-Free Cosmetics Act (HB 1047) by mobilizing our community of Brand Advocates who reside in Washington State,” Lee said. “Together, they made their voices heard by sending over 1,000 emails to their state legislators urging them to support and pass the bill.”
Laurie Valeriano, executive director of Toxic-Free Future, praised the upcoming Washington state law as “a huge win for public health and the environment that will have impacts that ripple across the nation.” She added that “companies won’t make special products for Washington state.” Instead, “they will reformulate and make products safer for everyone” — adults and children.

The new legislation will require Washington state agencies to assess the hazards of chemicals used in products that can impact vulnerable populations, while providing support for small businesses and independent cosmetologists to transition to safer products.

“When we go to a store, we assume the products on the shelf are safe, but this isn’t always true,” said Washington State Rep. Sharlett Mena, a Democrat serving in the 29th Legislative District (Tacoma), who sponsored the law. “I introduced this bill (HB 1047) because currently, the burden is on the consumer to navigate labels and find safe alternatives. You shouldn’t have to be a toxicologist to shop for shampoo.”
The new law aims to protect people of all ages, but especially youth. “Children are more susceptible to the impacts of toxic chemicals because their bodies are still developing,” Mena said. “Lead, for example, is significantly more hazardous to children than adults. Also, since children, unlike adults, tend to put things in their mouths all the time, they are more exposed to harmful chemicals in personal care and other products.”
Cosmetologists and hair professionals are taking notice. “Safety should be the practitioner’s number one concern” in using products on small children, said Anwar Saleem, a hair stylist, instructor and former salon owner in Washington, D.C., who is chairman of the D.C. Board of Barbering and Cosmetology and president of the National Interstate Council of State Boards of Cosmetology. “There are so many products on the market that it can be confusing.”
Hair products designed and labeled for children's use often have milder formulations, but “every child is unique, and what works for one may not work for another,” Saleem said. He recommends doing a patch test, in which the stylist or cosmetologist dabs the product on a small, inconspicuous area of the scalp or skin and waits anywhere from an hour to a day to check for irritation before continuing to serve the client. “Performing a patch test, observing children's reactions to a product and adequately adjusting are essential.”
Saleem seeks products that are free from harsh chemicals such as sulfates, phthalates and parabens, noting that these ingredients can be irritating and drying to the hair and scalp. If a child has sensitive skin or allergies, Saleem opts for hypoallergenic products.
We also need to ensure that less toxic alternatives are available and accessible to all consumers. It’s often under-resourced, low-income populations who suffer the burden of environmental exposures and do not have access or cannot afford these safer alternatives. -- Lesliam Quirós-Alcalá.
Lesliam Quirós-Alcalá, an assistant professor in the department of environmental health and engineering at the Johns Hopkins Bloomberg School of Public Health, said current regulatory loopholes on product labeling still allow manufacturers to advertise their cosmetics and personal care products as “gentle” and “natural.” However, she said, those terms may be misleading as they don’t necessarily mean the contents are less toxic or harmful to consumers.
“We also need to ensure that less toxic alternatives are available and accessible to all consumers,” Quirós-Alcalá said, “as often alternatives considered to be less toxic come with a hefty price tag.” As a result, “it’s often under-resourced, low-income populations who suffer the burden of environmental exposures and do not have access or cannot afford these safer alternatives.”
To advocate for safer alternatives, Quirós-Alcalá suggests that parents turn to consumer groups involved in publicizing the harms of personal care products. The Campaign for Safe Cosmetics is a program of Breast Cancer Prevention Partners, a national science-based advocacy organization aiming to prevent the disease by eliminating related environmental exposures. Other resources that inform users about unsafe ingredients include the mobile apps Clearya and Think Dirty.
“Children are not little adults, so it’s important to increase parent and consumer awareness to minimize their exposures to toxic chemicals in everyday products,” Quirós-Alcalá said. “Becoming smarter, more knowledgeable consumers is the first step to protecting your family from potentially harmful and toxic ingredients in consumer products.”
