The microbes living in the guts of males and females react differently to diet, even when the diets are identical, suggesting that therapies designed to improve human health and treat diseases through nutrition might need to be tailored for each sex.
The hallmark of an excellent researcher is an open mind. That flexibility and openness is what...
Researchers have established a new strategy to help surgeons see the entire tumor in the patient...
The effects of a commonly used anesthetic drug on memory and thinking appear to be temporary in...
What’s the difference between you and a rat? The list is unsurprisingly long but now, we can cross a universal human experience — feelings of regret — off of it.
Stimulating one of two dopamine-producing regions in the brain was able to arouse animals receiving general anesthesia with either isoflurane or propofol.
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.
Scientists have tested a non-surgical preventative treatment in a mouse model of peripheral vascular disease, and it was associated with increased blood circulation.
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.
