A number of papers in recent years have suggested there to be a link between gum disease (periodontitis) and neurodegeneration. Similarly to the correlation with heart disease, it is thought that the underlying mechanism is raised chronic inflammation deriving from toxins released into the bloodstream by the bacteria that cause […]

A group of scientists led by researchers at the University of North Carolina at Chapel Hill, Weill Cornell Medicine and NewYork-Presbyterian reported that the Moderna mRNA vaccine and a protein-based vaccine candidate elicited durable neutralizing antibody responses to SARS-CoV-2 in preclinical research. There were no adverse effects. The research, published […]

A chemist at The University of Texas at Arlington is developing a cancer medication that uses light to target and destroy tumor cells in a process known as photodynamic therapy (PDT). Sherri McFarland, professor of chemistry, and her team of researchers have developed a chemical compound containing the transition metal […]

Plenty of probiotic yoghurts, pickles, and kombuchas claim to boost our digestive health with armies of microbes, but some scientists have more ambitious therapeutic plans for the “bugs” that colonize us. They hope to leverage these microbes as living therapeutics for a range of health conditions, including ulcerative colitis, multiple […]

When people overconsume sugar-sweetened beverages, or SSBs, like soda, certain fruit juices, and some coffee and tea drinks, it can lead to many different health conditions, including obesity, cardiovascular disease and diabetes. Nonalcoholic fatty liver disease, or NAFLD, is the leading cause of liver disease in the United States, and […]

The first two COVID-19 vaccines authorized for emergency use by the Food and Drug Administration (FDA) employed a technology that had never before been used in FDA-approved vaccines. Both vaccines performed well in clinical trials, and both have been widely credited with reducing disease, but concerns remain over how long […]

Researchers at Tel Aviv University have created a new method of transporting RNA-based drugs to a subpopulation of immune cells involved in the inflammation process, and target disease-inflamed cells without causing damage to healthy cells that surround them. The new technology may revolutionize the treatment of cancer and a wide range of […]

The tiny mouse embryo has a heart that beats. Its muscles, blood vessels, gut and nervous system are beginning to develop. But this embryo is unusual: It was made in a lab, out of mouse embryonic stem cells, and represents the most sophisticated in vitro (in a dish) model of […]

Yassine Sassi decided as a boy growing up in Tunisia that he wanted to be a scientist. He isn’t sure why. There were no scientists among his family, no friends with the same ambition. But at 18 he left home for France to study biochemistry. Two decades later, he’s on […]

So many microbes live in and on your body that it might be helpful to think of them functioning collectively as separate organs. That’s because these tiny organisms that live primarily in our gut, collectively known as the microbiome, often perform helpful functions that keep the body running smoothly. Scientists […]

Therapy Manipulates the Immune System to Slow Neurodegeneration Without Triggering Dangerous Inflammation in the Process. A new therapy prompts immune defense cells to swallow misshapen proteins, amyloid beta plaques and tau tangles, whose buildup is known to kill nearby brain cells as part of Alzheimer’s disease, a new study shows. […]

A Mediterranean diet – high in fruit, vegetables, legumes, whole grains, olive oil and oily fish – may prevent the development of age-related macular degeneration (AMD), which is the leading cause of visual impairment in people over the age of 50. A new study published by researchers from Inserm and […]
