Pediatric cancer study shows usefulness of gene expression analysis

Analyzing gene expression in tumor cells from children with cancer is more likely to reveal targets for therapy than analysis of DNA mutations, according to a new study led by researchers at the UC Santa Cruz Genomics Institute. The study, published in JAMA Network Open, looked at 144 tumor samples from 128 […]

Scientists identify critical window for treatment of Alzheimer’s Disease

Neuroscientists at the University of Southampton have made a significant development in understanding how Alzheimer’s disease spreads through the brain, discovering a significant period of time where medical intervention could halt its onset. A hallmark of Alzheimer’s disease is the accumulation of tau protein in neurons which causes loss of […]

Study links high-salt diet and cognitive impairment

A high-salt diet may negatively affect cognitive function by causing a deficiency of the compound nitric oxide, which is vital for maintaining vascular health in the brain, according to a new study in mice from Weill Cornell Medicine researchers. When nitric oxide levels are too low, chemical changes to the protein tau […]

Arthritis risk linked to obesity may be passed down through generations

Arthritis affects one in five Americans, but according to the Centers for Disease Control and Prevention, that number jumps to one in three among people with obesity. Now, new research from Washington University School of Medicine in St. Louis suggests obesity may increase arthritis risk not only in obese people […]

One avocado a day helps lower 'bad' cholesterol for heart healthy benefits

Move over, apples — new research from Penn State suggests that eating one avocado a day may help keep “bad cholesterol” at bay. According to the researchers, bad cholesterol can refer to both oxidized low-density lipoprotein (LDL) and small, dense LDL particles. In a randomized, controlled feeding study, the researchers […]

Signaling waves determine embryonic fates

Timing is everything for young cells waiting to determine their identities. Research by Rice University bioscientist Aryeh Warmflash and graduate student Sapna Chhabra shows homogenous colonies of human embryonic stem cells use dynamic molecular signaling waves that pass from cell to cell and trigger them to differentiate. Once prompted, the cells begin to organize […]
