The research suggests that different factors influence rates of firearm homicide for black and white men across states.
A recent spike in homicide rates across the nation doesn't tell the whole story. According to a new UT Dallas study, long-term factors like segregation and poverty play a more significant role in increases than short-term fluctuations. The study found that most cities' homicide rates have remained relatively stable over time.

A recent study found that group meditation using the Transcendental Meditation program significantly reduced urban murder rates in large US cities, with an estimated 4,136 murders averted between 2007-2010. The reductions were consistent with the hypothesis that a sufficiently large group practice creates a positive effect on society.
A new Indiana University study found that adding more black police officers does not reduce police-involved homicides of black citizens. In fact, it may even increase the number of such shootings until a critical mass of 35-40% is reached.
A recent study by Northwestern University researcher Linda Teplin found alarming premature mortality rates among delinquent youth, with 111 deaths recorded 16 years after detention. The study revealed significant risk factors in adolescence, including drug dealing and gang membership, which increased the likelihood of later mortality.

A new study linked Florida's 'Stand Your Ground' self-defense law to a 24% increase in homicide rates and 31% rise in firearm-related injuries from 2005-2014. The research suggests the law's extension of lethal force rights in public led to increased violence, particularly among young adults and white populations.
The JAMA Internal Medicine theme series focuses on firearm violence, publishing research and opinion articles that highlight the impact of laws and policies. The studies examine trends in gun violence, the effectiveness of background checks, and the immunity of the firearm industry to tort litigation.
A narrative review of 34 studies found that stronger firearm laws, especially those with background checks and permit requirements, are associated with decreased firearm homicide rates. However, more research is needed to fully understand the impact of these laws.
A study by Columbia University's Mailman School found that 71% of New York State voters supported indicting police officers involved in the 2014 Eric Garner arrest after watching the video. This increase in support was attributed to the physical force used on Garner being a key factor in respondents' opinions.
A new study using NVDRS data reveals 21% of law enforcement officers were killed during ambushes, with 90% homicides committed with firearms.

The research also highlights differences in classification of offenses and mental disorder assessments between genders.
A new study by Michigan State University examines how successful US police departments clear more homicides. Departments that achieve this goal work closely with the community, adopt modern investigative tools, and employ a team approach to investigations.
In a study, MS patients showed more severe moral judgments than average, even in neutral conditions, attributing negative emotions to external causes. This 'externally oriented thinking' helps them minimize damage but also leads to an inability to reflect on emotions and identify real causes of their negative emotional state.
Research suggests that child homicide is responsible for approximately 1% of all neonatal deaths in South Africa. The majority of these deaths occur among infants aged 0-6 days, with abandonment being the most common method of homicide.
Exposure to violence during pregnancy may increase the risk of prematurity and low birthweight. A recent study by Queen Mary University of London and the University of Leicester found that mothers exposed to homicides had newborns with lower birthweights and higher rates of prematurity, particularly in the first trimester.
A new study suggests that large groups practicing the advanced TM-Sidhi program of Transcendental Meditation are associated with significant reductions in U.S. homicide and urban violent crime rates. The total drop in the homicide rate was 21.2% over a four-year period, resulting in an estimated 8,157 homicides averted.
A new study reveals that minority groups, particularly blacks and Hispanics, experienced significant declines in homicide victimization rates from 1990-2010. The drops were more pronounced for these groups than for whites, with black-white and Hispanic-black gaps narrowing by 40% and 55%, respectively.
