To treat large gaps in long bones, like the femur, which result from bone tumor removal or a shattering trauma, researchers at Penn Medicine and the University of Illinois at Chicago developed a process that partially recreates the bone growth process that occurs before birth. A bone defect of more […]

A mutation has been found in a rare form of brain aneurysm that might be treated with a drug already approved for cancer therapy. The finding suggests that other, more common, forms of aneurysms may be caused by yet undiscovered mutations.  These might also be treated with medication instead of […]

Schizophrenia, a psychiatric disorder that affects about 1% of the population, is a leading cause of functional disability in the United States. Typically diagnosis has hinged on the display of visible “positive symptoms” such as hallucinations and delusions, but one key to earlier identification and treatment is a recognition of […]

Nematodes, worms found in virtually all environmental habitats, are among the most studied model organisms. They reproduce quickly and their genome contains nearly the same number of genes as the human genome. A new Tel Aviv University study finds a mechanism exhibited in nematodes allows the nervous system cells — neurons — […]

A new study by researchers at the University of Virginia and other institutions has discovered a type of pigment cell in zebrafish that can transform after development into another cell type. David Parichy, the Pratt-Ivy Foundation Distinguished Professor of Morphogenesis in UVA’s Department of Biology, said that researchers in his […]

A new phase of the IGNITE Network will conduct clinical trials of genomic medicine interventions. The National Institutes of Health will fund clinical trials to assess the benefits, applicability and efficacy of applying genomic medicine interventions to improve management of diseases such as high blood pressure, depression and chronic pain. […]

Parkinson's disease is a debilitating neurodegenerative disease, affecting everything from speech, posture and gait to digestion, sleep, impulse control and cognition. Therapies exist that alleviate some symptoms of the disease, but there is still no cure for Parkinson's, which affects close to one million Americans and 10 million people worldwide. […]

A new study has found that not sticking to a regular bedtime and wakeup schedule — and getting different amounts of sleep each night — can put a person at higher risk for obesity, high cholesterol, hypertension, high blood sugar and other metabolic disorders. In fact, for every hour of variability […]

Pancreatic cancer kills more than 45,000 people in the U.S. each year, mostly due to the fact that it is detected too late for surgery to remove and halt the spread of the cancer. Cysts in the pancreas sometimes develop into the invasive cancer, depending on the type of cyst, […]

Like fishermen, Rice University bioengineers are angling for their daily catch. But their bait, biomolecules in a hydrogel scaffold, lures microscopic stem cells instead of fish. These, they say, will seed the growth of new tissue to heal wounds. The team led by Brown School of Engineering bioengineer Antonios Mikos and graduate student Jason Guo […]

Researchers at the University of Illinois at Chicago and the University of Pennsylvania have developed a unique technique that uses stem cells and flexible implantable bone-stabilizing plates to help speed the healing of large breaks or defects. The technique allows the stem cells applied to break sites to experience some […]

Cancer-related inflammation impacts significantly on cancer development and progression. New research has observed in zebrafish, for the first time, that inflammatory cells use weak spots or micro-perforations in the extracellular matrix barrier layer to access skin cancer cells. The research, led by the University of Bristol and published in Cell Reports, used translucent […]
