From 1999 to 2017, 38,942 US children ages 5 to 18 years old were killed by firearms, averaging more than 2,000 deaths a year. In 2017 alone, 2,462 school-age children were killed by firearms compared to 144 police officers and 1,000 active military worldwide who died in the line of duty. The study finds significant increases that began with an epidemic in 2009, followed by another one in 2014. Each of these epidemics has continued through 2017.
State breast density notification laws that mandate reporting of mammogram results can prompt further screening and modestly boost cancer detection rates, say researchers at Yale's School of Public Health and School of Medicine. Their study was published in the American Journal of Public Health.
Male and female serial killers tend to choose their victims and commit their crimes in different ways, which may be due to thousands of years of psychological evolution, according to researchers.
Patent law experts demonstrate that private-public partnerships lead to promising innovation output measured in patents. Collaborations between private entities and public institutions have the potential to improve technology transfer in nanotechnology. Nations entering the nano-space can capitalize on collaborative environments, developing frameworks and close institutional networks between entities active in nanotechnology.
Canada's largest food and beverage manufacturers could aim higher to improve nutrition, reduce obesity and prevent chronic disease, according to a new report by University of Toronto researchers.

Modern analytical tools like mass spectrometers can identify many unknown substances, allowing scientists to easily tell whether foods or medicines have been altered. However, the cost, size, power consumption and complexity of these instruments often prevent their use in resource-limited regions. Now, in ACS Central Science, researchers report that they have developed a simple, inexpensive method to identify samples by seeing how they react to a change in their environment.
Chicago's Large Lot Program is promoting positive change in inner-city neighborhoods by enabling residents to buy and repurpose vacant lots that attracted crime and other problems, a new study by University of Illinois researchers and the USDA Forest Service.
A UC researcher performed a secondary analysis of the 2016 National Youth Tobacco Survey, finding that of 1,579 adolescents between the ages of 12 and 17 who had admitted to using electronic cigarettes within the last 30 days of the survey, 13.6 percent were daily users. She further found that daily users were far more likely to obtain their electronic cigarettes and accessories from commercial sources than their non-daily using counterparts.
A new study from the CDC showed modest improvement in optimal hospital breastfeeding policy from 2009 to 2015, with more than 2 times as many hospitals having a model breastfeeding policy and increases in early initiation of breastfeeding and limitation of non-breast milk feeds of breastfed infants.
As states around the country move to stiffen punishments for animal cruelty, Michigan State University researchers have found a correlation between the types of animal abuse committed and the perpetrator's relationship to an animal and its owner.
