Key Takeaways
Helmet laws work (when they’re universal): Motorcycle riders in North Carolina (with a universal helmet law) wore a helmet 94% of the time compared with 47% of riders in South Carolina (partial law).
Helmets mean less severe injuries: Motorcyclists who wore helmets were less likely to die or require intensive care after an accident.
Lost progress: Helmet laws have been rolled back in many states resulting in only 19 states now having universal helmet laws.
CHICAGO — New research using a decade of data shows the lifesaving impact of universal motorcycle helmet laws. Researchers from the Carolinas Medical Center in Charlotte, North Carolina — an American College of Surgeons (ACS)-verified Level I trauma center — compared outcomes for motorcycle crash victims from North Carolina, where helmets are mandatory for all riders, and South Carolina, where only riders under 21 must wear them. The findings are published in the Journal of the American College of Surgeons (JACS).
Key Findings:
Helmet use was 94% in North Carolina vs. 47% in South Carolina during the study period.
Helmeted patients had less severe injuries, with lower Injury Severity Scores (13.6 vs. 16.0).
Riders without helmets were more likely to require care in the intensive care unit (ICU) (39% vs. 25%) after an accident.
Patients who were not wearing a helmet during a crash were uninsured more often, shifting costs to taxpayers.
“The two states’ differing laws created a natural experiment,” said senior author A. Britton Christmas, MD, MBA, FACS, medical director of trauma at Carolinas Medical Center. “The results are clear: helmets save lives, and universal laws ensure they’re used.”
States are Scaling Back Universal Helmet Laws
Despite evidence, only 19 states have universal helmet laws — a sharp decline from 47 states 50 years ago. Efforts from motorcycle groups have driven these repeals, even as trauma surgeons emphasize the consequences.
“I’ve testified against repeals in North Carolina because the data doesn’t lie,” said Dr. Christmas. “When helmets aren’t required, fewer people wear them, and more die or face life-altering injuries.”
These different laws impacted helmet usage in patients. Only 47% of patients with a home state of South Carolina were wearing a helmet at the time of injury, as compared to 94.2% of patients from North Carolina.
The Human Toll of No Helmets
The study also found:
Patients who weren’t wearing a helmet required longer ICU stays and more ventilator support.
South Carolina’s under-21 helmet law had low compliance: 33% of young riders were not wearing a helmet during crashes, compared to only 10% in North Carolina.
“Universal laws normalize helmet use,” said lead author Stephanie Jensen, MD, MPH. “When young riders see adults without helmets, they question their necessity, and the results are tragic.”
Surgeons as Advocates
The authors urge surgeons and physicians to advocate for helmet laws, citing their unique credibility. “Policymakers need to hear from those who treat these injuries,” said Dr. Jensen. “This isn’t about limiting freedom, it’s about preventing families from losing loved ones.”
The authors noted a limitation of the study is that the data excludes riders who died at the scene or had minor injuries not requiring trauma care.
Study coauthors with Drs. Jensen and Christmas are Ansley B. Ricker, MD; Ronald F. Sing, DO, FACS; Samuel W. Ross, MD, MPH, FACS; Kyle W. Cunningham, MD, MPH, FACS.

Infections from respiratory syncytial virus (RSV) in children requiring primary care led to significant societal economic costs from outpatient treatment and parental work absences in Europe, according to a study just published on Eurosurveillance.
The study sought to provide insights for public health policy and support costs and benefits analyses for RSV immunisation strategies. RSV infections are a leading cause of acute respiratory infections in children, with nearly all children experiencing at least one RSV infection by the age of 2. While some children develop a severe form of RSV disease that might require hospitalisation, ...
Machine learning at the core
‘Aurora uses state-of-the-art machine learning techniques to deliver superior forecasts for key environmental systems—air quality, weather, ocean waves, and tropical cyclones,’ explains Max Welling, machine learning expert at the University of Amsterdam and one of the researchers behind the model. Unlike conventional methods, Aurora requires far less computational power, making high-quality forecasting more accessible and scalable—especially in regions that lack expensive infrastructure.

COLUMBUS, Ohio – If you’ve ever regretted ordering a spicy meal, take note: A new study identifying molecules that suppress the heat of chili peppers hints at the possibility of adapting these compounds into an “anti-spice” condiment for food that’s too fiery to eat.
The research helps explain differences in chili pepper pungency, or spiciness, by identifying three compounds in a range of pepper samples that chemical analysis predicted, and study participants on a tasting panel confirmed, are linked to lower heat intensity.
The findings have multiple potential applications: customized chili pepper breeding, ...
The universe is full of cosmic radiation that can be measured here on Earth.
This cosmic radiation consists of –- produced by black holes, gigantic supernovae, or rotating neutron stars – a type of dead star. These particles contain energy.
Sometimes, however, cosmic rays have a much higher energy than usual. We have known about this since 1962, but we still don’t know why.
We also don’t know where this ultra-high-energy cosmic radiation comes from. Or do we?
Supermassive ...
When deciding whom to trust, people are more likely to choose individuals who grew up with less money over those who went to private schools or vacationed in Europe, according to research published by the American Psychological Association.
"Trust is essential for healthy relationships. Without it, romantic partnerships can fail, workplaces can suffer and social divisions can grow,” said lead researcher Kristin Laurin, PhD, a psychology professor at the University of British Columbia. “But what makes people trust someone in the first place?”
To find out, researchers ran a series of experiments with more than 1,900 participants. They explored whether someone's ...

When a physician says a procedure is “rarely risky,” what does that really mean? Although terms like “common” and “unlikely” may sound descriptive enough, experts in medical decision-making suggest that leaving out numbers may be misleading for patients.
In a paper published on April 29 in the Journal of General Internal Medicine, a team of researchers and clinicians explained that patients often overestimate risk estimates, like possible side effects or medical conditions, when given only verbal descriptions. They encourage doctors not to shy away from including numbers, offering a list of five science-backed tricks on how to make those ...
