A nationwide study analysing gun-control laws in the USA has found that just nine of the 25 state laws are effective in reducing firearm deaths. The research, published in The Lancet, suggests that if all US states were to expand the three laws that have the strongest effect on gun deaths--universal background checks for purchasing guns and ammunition, and firearm identification [1]--the national rate of gun deaths could be cut by over 90%.

Beyond the breakers, the ocean is like the Wild West. While not completely lawless, its vastness and remoteness make it hard to observe and more difficult to manage human activity.
CHAMPAIGN, Ill. -- In spite of the overwhelming evidence of a skills deficit, a depressed middle class and growing inequality, the state of Illinois continues to underinvest in public higher education. But considering higher education funding as an investment that lowers state welfare and prison costs, generates tax revenues and leads to economic growth in the future -- and not as mere consumption spending -- could reframe the debate, according to an article by a University of Illinois expert in the economics of education.
University of Florida Health researchers have identified a new strain of bacteria in the mouth that may keep bad bacteria in check -- and could lead to a way to prevent cavities using probiotics.
The researchers say the findings could lead to the development of a supplement that patients could take orally to prevent cavities.
Cleveland: In a combination of both clinical studies of over 4,000 patients and animal model studies, Cleveland Clinic researchers have demonstrated -- for the first time -- that gut microbes alter platelet function and risk of blood clot-related illnesses like heart attack and stroke.
WASHINGTON - Insufficient sleep can decrease a commercial motor vehicle (CMV) driver's level of alertness, which may increase the risk of a crash, yet little is known about effective ways to minimize that risk, says a new report from the National Academies of Sciences, Engineering, and Medicine.
The chances of incarceration in America are always higher for blacks than for whites or Hispanics, regardless of their level of wealth, according to a new study led by Khaing Zaw of Duke University in the U.S. In addition, blacks and Hispanics who had previously served jail time were significantly poorer than their white counterparts.
The overall revision rate for septorhinoplasty (a surgical procedure to fix the nose and nasal septum) was low at 3.3 percent although certain patient characteristics were associated with an increased rate of revision, according to an article published online by JAMA Facial Plastic Surgery.
People with leukaemia could be helped by new research that sheds light on how the body produces its blood supply.
Scientists are a step closer to creating blood stem cells that could reduce the need for bone marrow transplants in patients with cancer or blood disorders.
Enabling scientists to grow the stem cells artificially from pluripotent stem cells could also lead to the development of personalised blood therapies, researchers say.
A low cost, easy to use, urine test to diagnose tuberculosis (TB) among patients with HIV could help reduce the TB death rate of HIV-positive patients in hospital, according to a new study published in The Lancet today.
In Africa, nearly 40% of all adult deaths related to HIV or AIDS are due to tuberculosis, but almost half of the TB cases remain undiagnosed and untreated before death. The authors of the study, which was conducted in 10 hospitals in sub-Saharan Africa, say that if implemented more widely, this low-cost intervention could save thousands of lives per year.
School and family influences on physical activity may be stronger in boys than in girls in Australia, according to a study published March 9, 2016 in the open-access journal PLOS ONE by Rohan Telford from the University of Canberra, Australia, and colleagues.
Combing optical coherence tomography (OCT) with another advanced imaging technology may more accurately identify coronary artery plaques that are most likely to rupture and cause a heart attack. In a report being published online in JACC Cardiovascular Imaging, investigators from the Wellman Center for Photomedicine at Massachusetts General Hospital (MGH) describe the first use in patients of a catheter-based device utilizing both OCT and near-infrared autofluorescence (NIRAF) imaging.
March 9, 2016 - Transplantation of the periorbital tissues--the area surrounding the eyes--is a "technically feasible" alternative to protect a functioning eye in some patients being considered for facial transplant, according to a study in Plastic and Reconstructive Surgery--Global Open®, the official open-access medical journal of the American Society of Plastic Surgeons (ASPS).
Globally declining fish populations are a frequently cited ecological and commercial calamity, but relatively little attention has been paid to the specific threats faced by fish that gather and spawn in large groups, says Yvonne Sadovy, writing in an article for BioScience. The marine scientist, affiliated with the University of Hong Kong and Science and Conservation of Fish Aggregations (SCRFA), outlines the challenges unique to these populations.
March 9, 2016 - What's the best approach to mental health treatment for refugees with posttraumatic symptoms? One clinic with extensive experience in managing traumatized refugees recommends a medical approach combining psychoactive medications, long-term psychotherapy, and screening and treatment for associated health issues, according to a paper in the Journal of Psychiatric Practice, published by Wolters Kluwer.
