Exercise increases levels of a brain-protecting enzyme in mice, according to a new study from Johns Hopkins University. This finding could have implications for people with a variety of neurodegenerative diseases, such as Alzheimer's, Parkinson's, Huntington's, and epilepsy.
Using the substance bumetanide in newborn mice, scientists succeeded in attenuating the disease...
When a high-fat diet causes us to become obese, it also appears to prompt normally bustling...
Researchers from the University of Bristol have gained a new insight into how the circadian...
Champion of regeneration, the freshwater polyp Hydra is capable of reforming a complete individual from any fragment of its body. It is even able to remain alive when all its neurons have disappeared. Researchers have discovered how: cells of the epithelial type modify their genetic program by overexpressing a series of genes, among which some are involved in diverse nervous functions.
As humans have begun to live longer it has become clear that the quality of our lives is equally as important as the duration.
A new study found that gastrointestinal bypass surgery, which is used to treat morbid obesity and diabetes, reduced sugar-seeking behavior in mice by reducing the release of a reward chemical called dopamine in the brain. The findings suggest that positive outcomes are more likely if sugary foods seem less rewarding after surgery.
Cancer researchers at the University of Cincinnati have found a new target that could lead to therapies for a rare type of tumor.
The simple act of running may be sufficient to prevent long-term cognitive impairments caused by prenatal exposure to antiepileptic drugs, according to a study published November 19th in Stem Cell Reports.
During embryonic development, billions of neurons nimbly reposition themselves within the brain and spinal cord, and connect branches to form the neural circuits that ultimately control our movements, perception, and memory. Scientists have long sought to understand the driving forces in this meticulously choreographed dance.
Using technology invented at MIT, doctors may one day be able to monitor patients’ vital signs by having them swallow an ingestible electronic device that measures heart rate and breathing rate from within the gastrointestinal tract.
Northwestern Medicine scientists and international colleagues have identified a novel strategy for reducing the side effects of uncontrolled movement caused by the drug levodopa, commonly used to treat the stiffness, tremors and poor muscle control of Parkinson’s disease.
A new inter-disciplinary study led by researchers at Tufts University found that coconut oil effectively controlled the overgrowth of a fungal pathogen called Candida albicans in mice. In humans, high levels of C. albicans in the gastrointestinal tract can lead to bloodstream infections, including invasive candidiasis.
The final 50 chimpanzees held for research purposes in the U.S. are being released – a development cheered by animal-rights groups, but bemoaned by advocates of animal research.
University of Wisconsin scientists have succeeded in growing functional vocal-cord tissue in the laboratory, a major step toward restoring a voice to people who have lost their vocal cords to cancer surgery or other injuries.
A mathematical model developed by Brown University researchers is shedding new light on how zebrafish get their iconic stripes. The model helps to demonstrate how two dynamic processes—the movement of pigment cells across the skin, and the birth and death of cells as the fish grows—combine to keep zebrafish stripes in line.
In a new animal study, researchers found obesity and Type 2 diabetes negatively affected bone, but exercise prevented weight gain and diabetes and increased bone strength. These findings could inform interventions to improve bone health among individuals with obesity and Type 2 diabetes.
A heart medication prevented ovarian damage and improved survival in adolescent mice after chemotherapy, according to a new study from the University of Wisconsin-Madison. The drug, dexrazoxane (or dexra for short), could save lives as well as overcome limitations of current fertility treatments used during cancer treatment.
Scientists at the Children’s Medical Center Research Institute at UT Southwestern have determined how the body responds during times of emergency when it needs more blood cells.
