A new study published in the American Journal of Preventive Medicine found that local-level background checks are associated with a 27% lower firearm suicide rate and a 22% lower homicide rate compared to federal-level checks. States that rely on local-level checks have substantially lower rates of firearm suicides and homicides.
Researchers from UC Davis found that microstamping technology worked well for some guns, but poorly for others. The study tested six brands of semi-automatic handguns, two semi-automatic rifles, and a shotgun, and found varying levels of success depending on the weapon and type of code.
A groundbreaking study published in Injury Prevention found that California's tight gun show regulations significantly reduced undocumented gun sales and 'straw' purchases outside of the state. The research, led by UC Davis director Garen Wintemute, observed increased regulation without affecting attendance or business at gun shows.
A study in Injury Prevention reveals California's tougher gun show controls have drastically reduced the sale of firearms linked to crimes. The stricter regulations have also limited the availability of assault-style weapons and banned certain types of rifles and handguns.
A study by pediatric researcher Robert H. DuRant found that over 70% of families surveyed did not store their firearms safely in the home. The study emphasizes the importance of storing guns safely to prevent accidents and suicide, particularly among children.

A study by Harvard researchers found that households with guns are more likely to be involved in homicides, particularly among children and women. States with higher levels of gun ownership have significantly higher homicide victimization rates, driven mainly by gun-related homicides.
The study found that the number of firearm-related deaths dropped by at least 6% after the law took effect, with a decrease in average annual suicides from 491 to 246. The legislation also led to a significant decline in homicides and overall homicide rates fell by almost 2.5% per year.
A study found that parents of teenagers are more likely to store firearms unsafely in their homes compared to parents of younger children. The researchers surveyed 392 parents and found that nearly 42% of parents with teenage children had an unlocked firearm at home, whereas only 28.8% of parents with children under 12 had the same issue.
A study by Harvard researchers found that households with adolescents are more likely to store guns loaded and/or unlocked. Parents of older children may be less vigilant about securing firearms due to perceived responsibility.

The Virtual Environment Assault Amphibian Vehicle (VEAAV) training system was developed by a Navy-Marine Corps team in just six months.
A review of federal, state, and local gun laws found no conclusive evidence that these laws reduce gun-related deaths or violent crimes. Poor data, underreporting, and jurisdictional issues hindered the research, leading to a lack of knowledge about the effectiveness of current laws.
A study found that storing household guns locked, unloaded, or separate from ammunition significantly reduces the risk of unintentional and self-inflicted firearm injuries among adolescents and children. The study suggests that locking firearms and ammunition is an effective way to prevent access by youth.
A study found that households with parents visiting children's homes are more likely to store firearms unlocked and have poor medication storage practices. Homes with older adults and child visitors tend to have more firearms and less safe storage, but the difference is not statistically significant.

A recent study found that in 55% of homes with young children, household chemicals were stored in accessible locations, while one-third of U.S. gun owners kept firearms unlocked at home. The odds of reported unlocked storage of guns and household poisonous chemicals were two and a half times higher when young children visited.
State gun safe storage laws, which require gun owners to lock up their guns, were associated with a 8.3% decrease in suicide rates among 14- to 17-year-olds. The study found that these laws may have prevented 333 suicides among this age group between 1989 and 2001.

A study found that suicide rates among African-American males aged 15-24 increased by 14% from 1979 to 1997, while gun-related suicides rose to 70%. Healthcare providers should ask depressed youths about firearm access.
A new study by Johns Hopkins Bloomberg School of Public Health researchers found that Maryland's 1990 law banning Saturday night specials resulted in a 9% lower rate of gun homicides. The study suggests the law saved an average of 40 lives per year between 1990-1998.
Research suggests that targeted policing strategies can be effective in preventing assaults and injuries by increasing deterrence through education and punishment. The study also highlights the importance of specific, visible police work and increasing certainty of punishment.
A study found that law enforcement officers encourage the public to use gun locks to make stored guns less dangerous, but they don't seem to like using the locks themselves. Only half of the officers who received free keyed cable gun locks accepted them, and two-thirds of those who did later reported not using the locks.
A new study by Johns Hopkins Bloomberg School of Public Health finds that states with mandatory licensing and registration of handguns reduce the number of crime guns sold by in-state dealers. Cities with stricter gun laws have lower rates of crime guns sold outside the state, supporting the benefits of comprehensive handgun sales laws.

The technique combines statistical data analysis and stability analysis to track and explain the sources of tremor.
The paper attributes the decline in homicide since the early 1990s to changes in drug markets, police response to gun carrying by young males, and economic expansion. Fewer handguns were used in homicides, especially among juveniles and young adults.
Student engineers at Johns Hopkins University designed a low-tech, affordable childproofing device for handguns that can be defeated by adults but not young children. The device automatically switches the gun back to safe mode when it leaves an adult's hand, providing passive protection.
The Red Cross has identified new 'cruel weapons' such as sound beams, sticky foam, capture nets, and microwaves that can cause severe injuries. The organization's SIrUS Project aims to outlaw these weapons by defining superfluous injury and unnecessary suffering based on scientific data.
