The researchers looked at all recorded gun deaths across the USA between 2000 and 2010, to include murders, suicides, and unintentional shooting, using data from the Injury Statistics Query and Reporting System.

Hawaii recorded the lowest rate of gun deaths at 3.02 per 100 000 citizens, while the District of Columbia topped the league table at 21.71 per 100 000. Rates rose in Florida and Massachusetts, largely owing to more gun deaths among people of white and non-Hispanic ethnicities, and an increase in the gun related murder rate.

PULLMAN, Wash. - Washington State University researchers have developed a unique method to use microbes buried in pond sediment to power waste cleanup in rural areas.

The first microbe-powered, self-sustaining wastewater treatment system could lead to an inexpensive and quick way to clean up waste from large farming operations and rural sewage treatment plants while reducing pollution.

stigators from the Institute for Research in Immunology and Cancer (IRIC) at the Université de Montréal have just published, in the prestigious magazine Science, the announcement of the discovery of a new molecule, the first of its kind, which allows for the multiplication of stem cells in a unit of cord blood. Umbilical cord stem cells are used for transplants aimed at curing a number of blood-related diseases, including leukemia, myeloma and lymphoma. For many patients this therapy comprises a treatment of last resort.

Dartmouth researchers and their colleagues have built the first smartphone app that automatically reveals students' mental health, academic performance and behavioral trends. In other words, your smartphone knows your state of mind -- even if you don't -- and how that affects you.

The StudentLife app, which compares students' happiness, stress, depression and loneliness to their academic performance, also may be used in the general population – for example, to monitor mental health, trigger intervention and improve productivity in workplace employees.

New research led by Queen's University professor Robert Campbell (Ophthalmology) has revealed using anti-inflammatory medications after glaucoma laser surgery is not helpful or necessary.

Glaucoma is the most common cause of irreversible blindness in the world and about 400,000 Canadians are afflicted with the disease, which is mainly caused by pressure within the eye being high enough to damage the optic nerve. The optic nerve is responsible for sending messages from the eye to the brain and is a vital part of vision.

As a result of outbreaks of violence in the nation's schools, concerns have grown about school safety and the overall well-being of students.

In a new study, UT Dallas criminology researchers have found that certain factors affect students' willingness to report weapons at school.

Curtin University research that monitors the volume of water in the Nile River Basin will help to level the playing field for more than 200 million North-East Africans who rely on the river's water supply.

Despite being arguably the longest river in the world, winding through nine different countries, the Nile River is shallow and has a low volume, making its water precious, particularly to those countries located downstream.

Imagine being able to switch out the batteries in electric cars just like you switch out batteries in a photo camera or flashlight. A team of engineers at the University of California, San Diego, are trying to accomplish just that, in partnership with a local San Diego engineering company.

As nations zero in on the UN's post-2015 global Sustainable Development Goals, innovations being successfully pioneered and demonstrated in Malaysia offer several proven tactical ideas for improving the world, says an influential international sustainable development networking organization.

A chin strap that can harvest energy from jaw movements has been created by a group of researchers in Canada.

It is hoped that the device can generate electricity from eating, chewing and talking, and power a number of small-scale implantable or wearable electronic devices, such as hearing aids, cochlear implants, electronic hearing protectors and communication devices.

The first results of the device's performance have been published today, 17 September, in IOP Publishing's journal Smart Materials and Structures.

New research led by the University of Leicester in the UK gives a blow-by-blow account of the injuries inflicted on King Richard III's body at the Battle of Bosworth Field on Aug 22, 1485. Modern forensic analysis of the King's skeletal remains reveals that three of his injuries had the potential to cause death quickly—two to the skull (page 4, figure 4) and one to the pelvis (page 5, figure 6).

WEST LAFAYETTE, Ind. - Ensuring that corn absorbs the right balance of nitrogen, phosphorus and potassium is crucial to increasing global yields, a Purdue and Kansas State University study finds.

Wearable electronic activity monitors hold great promise in helping people to reach their fitness and health goals. These increasingly sophisticated devices help the wearers improve their wellness by constantly monitoring their activities and bodily responses. This information is organized into companion computer programs and mobile apps.

As the number of children with food allergies in the U.S. increases, so does the risk of children having a severe, potentially life-threatening allergic reaction called anaphylaxis on school campuses. School nurses often have treatment plans in place for students with diagnosed allergies, but many children have their first allergic reactions at school, where a specific medication, such as EpiPen epinephrine injectors, may not be available and a response protocol may not be in place.
