Gamma waves have been associated with higher-level brain function, and disturbances in the patterns have been tied to schizophrenia, Alzheimer's disease, autism, epilepsy and other disorders. Now, research shows that little known supportive cells in the brain known as astrocytes may in fact be major players that control these waves.
What’s the difference between you and a rat? The list is unsurprisingly long but now, we can...
Stimulating one of two dopamine-producing regions in the brain was able to arouse animals...
Scientists have tested a non-surgical preventative treatment in a mouse model of peripheral...
Russia’s space agency has re-established communication with its Foton-M4 satellite in Earth’s low orbit, three days after losing contact. The robotic spacecraft contains geckos participating in experiments on how space conditions impact reproduction.
Scientists have discovered how to manipulate and maintain human embryonic stem cells in a “naïve” or base pluripotent state similar to that of mouse ESCs without the use of any reprogramming factors.
Cancer has long been thought to be primarily a genetic disease, but in recent decades scientists have come to believe that epigenetic changes also play a role, but direct evidence has been lacking. Now, researchers have created a mouse model providing the first in vivo evidence that epigenetic alterations alone can cause cancer.
A protein that controls when genes are switched on or off plays a key role in specific areas of the brain to regulate metabolism, researchers have found.
An experimental anti-inflammatory drug can protect vulnerable neurons and reduce motor deficits in a rat model of Parkinson’s disease, researchers have shown.
Exposure to light at night, which shuts off nighttime production of the hormone melatonin, renders breast cancer completely resistant to tamoxifen, a widely used breast cancer drug. A study shows that melatonin is vital to the success of tamoxifen in treating breast cancer.
Scientists have found that some melanoma cells are particularly fast growing, but not very good at invading the surrounding tissue, while other melanoma cells are the opposite — highly invasive but slow-growing. In a tumor, the faster growing cells "piggy-back" along with the more invasive cells.
Neuroscientists have succeeded in providing new insights into how the brain works. Researchers analyzed tissue samples from mice to identify how two specific proteins act upon the brain’s memory center. These molecules, which have similar counterparts in humans, affect the connections between nerve cells and influence the transmission of nerve signals into the hippocampus.
A research team has pinpointed a surprising mechanism behind neurodegeneration in mice, one that involves a defect in a key component of the cellular machinery that makes proteins, known as transfer RNA or tRNA.
Cardiovascular researchers have successfully used a protein known as MG53 to treat acute and chronic lung cell injury. Additionally, application of this protein proved to prevent lung cell injury.
Researchers have shown that in the fly Drosophila melanogaster the protein p53 is activated in certain cells to adapt the metabolic response to nutrient deprivation, thus having a global effect on the organism.
Currently, no cure exists for Alzheimer’s disease. But scientists are now reporting new progress on a set of compounds, initially developed for cancer treatment, that shows promise as a potential oral therapy for Alzheimer’s.
A therapy combining salmon fibrin injections into the spinal cord and injections of a gene inhibitor into the brain restored voluntary motor function impaired by spinal cord injury, scientists have found.
Fragile X syndrome (FXS) is a genetic disorder that causes obsessive-compulsive and repetitive behaviors, and other behaviors on the autistic spectrum, as well as cognitive deficits. It is the most common inherited cause of mental impairment and the most common cause of autism. Now, biomedical scientists shed light on the cause of autistic behaviors in FXS.
A study reveals a novel pathway in the pathophysiology of epilepsy. Researchers have identified the basic cellular mechanism that goes awry in prickle mutant flies, leading to the epilepsy-like seizures.
