Children and adolescents injured in motor vehicle accidents have better outcomes when treated at a stand-alone Level I pediatric trauma center than at general adult trauma centers or adult trauma centers with added Level I pediatric qualifications, according to a new study.
States with higher estimated levels of gun ownership had higher incidents of gun-related suicides, with firearm ownership alone explaining 71 percent of the variation in state-level gun suicide rates for males and 49 percent for females, a new study shows.
A key biochemical enables bacteria to repair otherwise fatal damage to their DNA, including that caused by antibiotics, report scientists. The study results revolve around the delicacy of DNA molecules, the letters making up the genetic code. Show More Summary
During embryonic life, the emergence of body limbs is orchestrated by a family of architect genes, which are themselves regulated by two DNA structures. While the first presides over the construction of the arm, the other takes over for the development of the hand. Show More Summary
High levels of the protein p62 in human liver samples are strongly associated with cancer recurrence and reduced patient survival, scientists have discovered. In mice, they also found that p62 is required for liver cancer to form.
A malicious form of ATF2, a protein that drives the formation of melanoma, has been discovered by a research team. In a new study, researchers looked at the oncogenic potential of a 'dead' form of ATF2 in mice with mutations in BRAF, a kinase that transmits signals promoting cell division and is often mutated in pigmented skin cells.

New findings yield insights into how plants get their traits. Revealing a landscape of protein-binding zones on DNA, collectively dubbed the "cistrome," shows how plants control where and when genes are expressed. Previous methods for...Show More Summary
Refugee children had similar academic success as other children if adequately supported, despite having more behavioral and emotional problems overall, a comprehensive review has found.
Misconduct within an organization is generally seen as a predicament at best, a catastrophe at worst. But a new study shows that such misconduct, or “deviance,” can prove beneficial by causing “non-deviant” members of the group to work harder in order to alleviate their own discomfort with the organization’s tarnished image.
Researchers have generated antibodies that reprogram a type of macrophage cell in the tumor, making the immune system better able to recognize and kill tumor cells. The study, say the scientists, could lead to a new therapy and provide a potentially important diagnostic tool for breast cancer and malignant melanoma.
Calcium phosphate is a widespread biomineral in the animal kingdom: Bones and teeth largely consist of this very tough mineral substance. Researchers now for the first time demonstrate the presence of calcium phosphate as a structural biomineral in higher plants. Show More Summary
To make the world safer against future infectious disease threats, national health systems should be strengthened, the World Health Organization's emergency and outbreak response activities should be consolidated and bolstered, and research and development should be enhanced, says a new article.
Roboticists demonstrate that their flying microrobots, nicknamed the RoboBees, can now perch during flight to save energy - like bats, birds or butterflies.
Recently, a team of scientists examined the whole-joint gene expression by RNA sequencing at one day, one, six and 12 weeks after injury. The team used a new, non-invasive tibial compression mouse model of PTOA, that mimics ACL rupture in humans from a single high-impact injury.
A common diagnostic tool often used to identify patients at risk of bleeding may also be used to identify those predisposed to clot excessively, new findings from a retrospective study has found.
Dazzle camouflage, as used on World War I battleships to fool U-boat commanders, has been modernized for the twenty-first century with moving patterns. New research has found that these moving patterns can cause a marked change in perceived speed. This would be enough to cause a targeting error of up to 2m for a Land Rover at a distance of 70m, moving at 55mph.
Scientists have developed a new material, called 'rewritable magnetic charge ice,' that permits an unprecedented degree of control over local magnetic fields and could pave the way for new computing technologies.
A large proportion of cancer cases and deaths among U.S. individuals who are white might be prevented if people quit smoking, avoided heavy drinking, maintained a BMI between 18.5 and 27.5, and got moderate weekly exercise for at least 150 minutes or vigorous exercise for at least 75 minutes, according to a new study.
On May 12, 2016, astronomers using NASA's Hubble Space Telescope captured this striking image of Mars, when the planet was 50 million miles from Earth. The photo reveals details as small as 20 miles to 30 miles across. This observation...Show More Summary
A new study has identified a 'sunscreen' gene that may help stave off skin cancer. Researchers found that the 'UV radiation Resistance Associated Gene' is a tumor suppressor for skin cancer, which is the most common form of cancer in the United States. Show More Summary
