Until a child's bones have fully matured (in girls, typically by age 14; in boys, age 16), an injury to the anterior cruciate ligament -- the primary, stabilizing ligament of the knee joint -- requires special consideration, treatment and care to ensure a
We take it for granted that our chromosomes won’t stick together, yet this kind of cellular disaster would happen constantly were it not for a protein called TRF2. Now, scientists have discovered key details of how TRF2 performs this crucial chr
When motors break down, getting where you want to go becomes a struggle. Problems arise in much the same way for critical brain receptors when the molecular motors they depend on fail to operate. Now, researchers have shown these broken motors induce stre
The vital role filled by volunteer subjects – both sick and healthy – is an often-underappreciated aspect of clinical research at academic medical centers and other institutions.
Men who reported permanent stress have a significantly higher risk of developing type 2 diabetes than men who reported no stress. This is the finding of a 35-year prospective follow-up study of 7,500 men in Gothenburg, Sweden.
Psychological well-being has been linked to many important life outcomes, including career success, relationship satisfaction, and even health. But it's not clear how feelings of well-being change as we age, as different studies have provided evidence for

Researchers have demonstrated a high cure rate and remarkably few side effects in treating patients with cutaneous leishmaniasis (CL) with an investigational antibiotic cream. CL is a parasitic disease that causes disfiguring lesions, with 350 million peo
U.S. soldiers in combat often suffer constricted blood vessels and increased pressure in the brain -- significant complications of traumatic brain injuries, according to new research.
It's established dogma that the immune system develops a "memory" of a microbial pathogen, with a correspondingly enhanced readiness to combat that microbe, only upon exposure to it -- or to its components though a vaccine. But a discovery casts
Researchers have shown for the first time that it is possible to cure diabetes in large animals with a single session of gene therapy. After a single gene therapy session, the dogs recover their health and no longer show symptoms of the disease. In some c
One in every 20 cases of the serious condition of pregnancy, pre-eclampsia, may be linked to increased levels of the air pollutant ozone during the first three months, suggests a large study.
Devising a method for more precise and less invasive treatment of cancer tumors, scientists have developed a degradable nanoscale shell to carry proteins to cancer cells and stunt the growth of tumors without damaging healthy cells.
Marijuana use may double the risk of stroke in young adults. The New Zealand findings are the first from a case-controlled study to indicate a potential link between marijuana and stroke.
Researchers have identified a gene that may better predict survival for pancreatic adenocarcinoma, the fourth leading cause of cancer deaths in the United States. The scientists conducted a study that better defines the role of ribonucleotide reductase M1
Access to public schools is one explanation for the educational gap between students in rich and poor countries, but a new study shows mortality and fertility rates are more significant factors.
Scientists in Canada have discovered a trigger that turns muscle stem cells into brown fat, a form of good fat that could play a critical role in the fight against obesity.
A high intake of supplemental calcium appears to be associated with an increased risk of cardiovascular disease (CVD) death in men but not in women in a study of more 388,000 participants between the ages of 50 and 71 years, according to a new report.
A record number of U.S. children were covered by health insurance in 2011, mostly due to substantial increases in the enrollment rates of public insurance, according to new research.
Preliminary evidence from a clinical trial suggests that treatment with glucagon-like peptide-1 (GLP-1) receptor agonists was associated with reduced body mass index and body weight in adolescents with severe obesity, according to a new report.
Having adequate levels of vitamin D during young adulthood may reduce the risk of adult-onset type 1 diabetes by as much as 50 percent, according to researchers. The findings, if confirmed in future studies, could lead to a role for vitamin D supplementat
