Researchers find thousands of pediatric firearm deaths linked to more permissive state gun laws

2025-06-09
(Press-News.org) Guns are now the leading cause of death for youth in the United States. Researcher from Mass General Brigham investigated whether firearm mortality rates among U.S. children ages 0-17 changed in the 13 years following a 2010 Supreme Court ruling that applied the Second Amendment to state and local governments. In states with the most permissive firearm laws, they found evidence of 6,029 more pediatric deaths due to firearms than would have been expected based on the existing demographic trends—and more than 1,400 excess deaths in states with permissive firearm laws. Rates remained unchanged or decreased in states with more strict laws. The results are published in JAMA Pediatrics.

“We saw over 7,400 more pediatric deaths due to firearms than would have been expected,” said first author Jeremy Faust, MD, an emergency physician at Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system. “And when checked against other causes of death, including homicides and suicides not involving firearms, there were not similar changes. This show that differences in firearm laws matters.” 

The study categorized states as either most permissive, permissive, or strict based on gun ownership and use policies, and compared their pediatric firearm mortality rates before the ruling (from 1999-2010) and after the ruling (2011-2023). The researchers also found that existing disparities for pediatric firearm deaths among Black youth increased in permissive states and persisted, but did not increase, in states with more strict laws. The team plans to share their findings with policy makers and stakeholders and hopes to see future research identify which specific policies are most effective.

“Addressing the epidemic of pediatric firearm mortality requires collective action and policy change,” said Onyeka Otugo, MD, MPH, MPA, an author on the study and an emergency physician at Brigham and Women’s Hospital. “Gun laws truly make a difference for the collective safety of children.”

Landmark test for coeliac disease promises to take away the pain of diagnosis

2025-06-09
Imagine having to eat something that makes you sick – just to see what’s making you ill in the first place.  That’s the harsh reality of current diagnostic tests for coeliac disease, which require people to eat large amounts of gluten for weeks in order to get an accurate diagnosis. But this painful process could soon be a thing of the past, with WEHI researchers and industry partner Novoviah Pharmaceuticals developing a world-first blood test that can identify the condition in patients – even when they’re on gluten-free diets.   At a glance New clinical research published in the high-impact ...

A recipe for success: beefing up the taste of cultured meat with amino acids

2025-06-09
Tokyo, Japan – Across the world the demand for meat is growing, despite associated environmental and animal welfare costs. Although lab-grown – or cultured – meat could be part of the answer, scientists have yet to perfect one crucial detail: the taste. In an article to be published in Food Chemistry, researchers from the Institute of Industrial Science, The University of Tokyo, have measured and found a way to control the key amino acids responsible for flavor in a step toward making cultured meat taste just like the real thing. The push toward cultured meat has been adopted because conventional production is not a sustainable solution for ...

Protecting peppers from devastating viral diseases through gene pyramiding

2025-06-09
Even with today’s advanced agricultural technologies, plant diseases can still be extremely devastating to crops, causing billions of dollars in losses worldwide every year. Begomoviruses represent a prominent example of this threat—these whitefly-transmitted pathogens cause yellow leaf curl disease in peppers and can destroy up to 100% of fruit yield in affected fields across Asia, Africa, and the Americas. Breeding crops that are resistant to begomoviruses has long been the most effective and widely used strategy for preventing such massive losses. Though usually effective, this approach has serious limitations, especially when dealing with mixed infections. Scientists ...

Lizards of Madagascar

2025-06-09
Kyoto, Japan -- After the island of Madagascar drifted away from India 88 million years ago, isolating it from all other landmasses, its flora and fauna evolved in seclusion. As these transformed into plants and animals completely unique to their island, Madagascar became a biodiversity hotspot unlike anywhere else on Earth. An important facet of this biodiversity is an ecological process called endozoochory, which is when animals eat plant seeds and then poop them out somewhere else, aiding in the spread of the plants. Most research on endozoochory has focused on the roles of ...

Beyond the brain: how BCIs are rewiring medicine and redefining humanity

2025-06-09
Brain-computer interface (BCI) technology is opening an unprecedented chapter in human-machine integration by establishing direct communication between the brain and external devices. Once a science fiction concept, BCI is now reshaping the landscape of neurosurgery and neurorehabilitation. By decoding brain signals to restore lost motor, sensory, and language functions, BCIs offer new hope for individuals affected by paralysis, aphasia, and neurodegenerative diseases. But their impact extends well beyond the clinic—BCIs are poised to influence cognition, ethical governance, and national security. As this disruptive technology matures, ...

Fossilized dinosaur gut shows that sauropods barely chewed

2025-06-09
Plant fossils found in the abdomen of a sauropod support the long-standing hypothesis that these dinosaurs were herbivores, finds a study publishing June 9 in the Cell Press journal Current Biology. The dinosaur, which was alive an estimated 94 to 101 million years ago, ate a variety of plants and relied almost entirely on its gut microbes for digestion.   “No genuine sauropod gut contents had ever been found anywhere before, despite sauropods being known from fossils found on every continent and despite the group ...

School dental treatments stop kids’ tooth decay in its tracks

2025-06-09
Two topical treatments applied to kids’ cavities can stop the majority of them from progressing for years, according to a study led by NYU College of Dentistry and published in JAMA Network Open. Treating more than 10,000 cavities in New York City elementary school students, the researchers found that both atraumatic restorations (ART) and silver diamine fluoride (SDF) kept most dental decay from worsening, supporting the use of non-surgical approaches for managing cavities. Children miss an estimated 34 million hours of school each year due to emergency dental care. Bringing cavity prevention programs to schools can improve kids’ oral health and stave ...

How high is your dementia risk? It might depend on where you live

2025-06-09
In one of the largest and most comprehensive studies of its kind, a research team led at UC San Francisco has identified the regions where dementia occurs most often.  What They Discovered Using the Mid-Atlantic* as the basis for comparison, researchers found that dementia rates were 25% higher in the Southeast.** The Northwest*** and Rocky Mountains**** were both 23% higher, and the South***** was 18% higher. The Southwest, which includes California, was 13% higher; while the Northeast, which includes New York, was 7% higher.  These differences remained when researchers accounted for factors like age, ...
