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 […]

Crimped or straight? Lung fiber shape influences elasticity

Take a deep breath. Now exhale. Congratulations! You’ve just done something completely ordinary, yet so mysterious that scientists still don’t know everything about it. How oxygen and carbon dioxide enter and leave the bloodstream is well known, but scientists are just beginning to understand what happens to respiratory tissues as […]

Clues to improve cancer immunotherapy revealed

Cancer immunotherapy drugs trigger the body’s immune system to attack tumors and have revolutionized the treatment of certain cancers, such as lymphoma, lung cancer, and melanoma. Yet, while some patients respond well to the drugs, others don’t respond at all. Cancer immunologists want to change that. A new study by […]

Biologists build proteins that avoid crosstalk with existing molecules

Inside a living cell, many important messages are communicated via interactions between proteins. For these signals to be accurately relayed, each protein must interact only with its specific partner, avoiding unwanted crosstalk with any similar proteins. A new MIT study sheds light on how cells are able to prevent crosstalk […]
