People with cancer are more than four times more likely to commit suicide than people without cancer, according to Penn State College of Medicine researchers. In a study using data on more than eight million cancer patients in the United States, the researchers also found that among people with cancer, white males; patients who were …
As we age, our bodies undergo biological changes that cause a decline in the function of our cells and tissues. However, most studies attempting to identify molecules involved age-related dysfunctions have focused only on mechanisms based on mRNA transcription, a very important step in gene expression, but nonetheless only part of the complex regulatory mechanisms …
Influenza virus, the causative agent of flu, primarily targets the respiratory tract and infects epithelial cells here. The epithelial cells of the nose and throat are enveloped by complex bacterial communities, leading Foxman and colleagues to hypothesize that this respiratory microbiome might interact with the virus – and could play a role in the body’s …
Huang and Cornell found that a 10 percentage point increase in voters supporting the Republican candidate in 2016 was associated with a 5 percent jump in middle school teasing because of race or ethnicity and an 8-percent increase in middle school bullying. “We found consistent differences in teasing and bullying rates that were linked to …
Public goods spending makes communities “more livable, with more amenities,” Flavin said. “If roads are completed and kept up, so that people aren’t stuck in traffic, they have more time to do things they enjoy doing. Large parks are social spaces — and one clear finding of happiness studies is that people who are more …
High blood pressure has been linked to an increased risk for dementia, but what’s unclear is what kinds of subtle negative changes take place in the brain that may affect cognitive function. Finding new ways to detect minor types of cognitive impairment may help determine who is at risk for early-stage dementia. In this study, …
Using mice deficient in nestin, a protein that is a component of the part of the cytoskeleton known as intermediate filaments or nanofilaments, the research team led by Prof. Milos Pekny showed that nestin produced in astrocytes has an important role in inhibiting neuronal differentiation. They linked this regulatory function of nestin to the Notch …
If only we could keep our bodies young, healthy and energetic, even as we attain the wisdom of our years. New research at the Weizmann Institute of Science suggests this dream could be at least partly obtainable in the future. The results of this research, led by Prof. Valery Krizhanovsky and Dr. Yossi Ovadya in …
A new neurostimulator developed by engineers at the University of California, Berkeley, can listen to and stimulate electric current in the brain at the same time, potentially delivering fine-tuned treatments to patients with diseases like epilepsy and Parkinson’s. The device, named the WAND, works like a “pacemaker for the brain,” monitoring the brain’s electrical activity …
