by British Medical Journal Credit: CC0 Public Domain A high intake of alpha linolenic acid (ALA)—found mainly in nuts, seeds, and plant oils—is associated with a lower risk of death from all causes, and specifically from diseases of the heart and blood vessels, finds a study published by The BMJ today. Higher ALA intake was associated with a...

Using a novel technique, researchers at Karolinska Institutet have been able to study what happens in the brain when the central nervous system judges a smell to represent danger. The...

by Amanda Dyslin Credit: Unsplash/CC0 Public Domain Q: I’ve heard some theories circulating about the COVID-19 vaccine, including that it was developed to control the general population through microchip tracking or “nanotransducers” in our brains. I’ve also heard that it will alter my DNA. Are these theories true? A: No, those assertions are false. “There...

by Institute of Cancer Research Credit: Jan Chlebik, ICR Immune-related genes are associated with the development of the rare cancer ovarian clear cell carcinoma (OCCC), new research has found. A new study led by researchers at the Institute of Cancer Research, London, investigated the immune characteristics of OCCC and uncovered gene alterations linked to poor prognosis for the disease. It also identified specific immune cells that...

by Ingrid Fadelli , Medical Xpress Expression of light sensitive protein (channel rhodopsin, ChR2) in pacemaker cells in the medial septal area (MSA), along with light delivery to MSA, allows for light-controlled pacing of oscillatory brain activity in brain regions, such as the medial entorhinal cortex (MEC). Quirk and colleagues show that accelerating the pace...
by Wellcome Trust Sanger Institute Credit: CC0 Public Domain For the first time, DNA mutations in liver cells have been identified that impact metabolism and insulin sensitivity in patients with liver disease. These mutations are specific to liver disease that is associated with obesity, type 2 diabetes, and chronic alcohol consumption. The study, from the Wellcome...
