ANDREW STAPLETON Scientists have developed a thin flexible battery suited to implantable devices that does away with dangerous chemicals and replaces them with biologically compatible liquids. The bendy batteries use sodium-based liquids – one a saline solution and another using cell cultures – and this innovation could change how we power wearable devices and even...
By Sally Robertson, B.Sc.,Oct 25 2020 Researchers at Trinity College Dublin have provided an updated estimate of the incubation period for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent causes coronavirus disease 2019 (COVID-19). Initial estimates made during the early stages of the pandemic ranged from around 4 to 7 days. However, numerous reports have since...
by Jacob Shea, University of California – Berkeley The miR-128-1 microRNA, a tiny snippet of regulatory RNA emanating from the ‘dark matter’ of the genome previously thought to be junk DNA, controls energy metabolism and contributes to metabolic diseases such as obesity and type 2 diabetes. It is linked to human evolutionary selection for survival of...
by German Cancer Research Center What role do the lymphatic vessels play in the metastasis of cancer cells? Scientists from the German Cancer Research Center and the Mannheim Medical Faculty of the University of Heidelberg developed a method to investigate this question in mice. The aim of the work was to identify new ways to block the dangerous colonization and...
by American Heart Association People with severe obesity (BMI >35) and a prior heart attack who undergo weight-reduction surgery may lower their risk of a second heart attack, major cardiovascular event, heart failure and death compared to people with similar medical histories who did not have weight-reduction surgery, according to new research published today in Circulation. “It is well...
CHILDREN’S NATIONAL HOSPITAL T-cells taken from the blood of people who recovered from a COVID-19 infection can be successfully multiplied in the lab and maintain the ability to effectively target proteins that are key to the virus’s function, according to a new study published Oct. 26 in Blood. “We found that many people who recover from COVID-19 have...
UNIVERSITY OF COPENHAGEN THE FACULTY OF HEALTH AND MEDICAL SCIENCES The muscles and joints are not the only parts of the body to be worn down by physical work. The brain and heart suffer too. A new study from the University of Copenhagen shows that people doing hard physical work have a 55-per cent higher...
SCUOLA INTERNAZIONALE SUPERIORE DI STUDI AVANZATI IMAGE: THE SCIENTISTS DEVELOPED AN EXPERIMENTAL TECHNIQUE ABLE TO DETECT THE PROTEIN TDP-43 EVEN WHEN IT IS PRESENT IN THE BODY IN MINUTE QUANTITIES AND IN THE EARLIER STAGES OF DISEASE. A test to diagnose two very serious diseases such as ALS and FTD when the pathologies have not...
NATIONAL RESEARCH COUNCIL OF SCIENCE & TECHNOLOGY IMAGE: CONCEPTUAL DIAGRAM OF BIO-ORGANIZATIONAL CRUSHING TECHNOLOGY BASED ON HIGH-INTENSITY CONCENTRIC ULTRASONOGRAPHY. Focusing ultrasound energy on a target site in the body to generate heat can burn and destroy the tissue in the site without a surgical procedure. This method is clinically applied to treat uterine fibroids, prostatic hyperplasia, prostate...
An international team of researchers has identified a direct molecular link between meat and dairy diets and the development of antibodies in the blood that increase the chances of developing cancer. This connection may explain the high incidence of cancer among those who consume large amounts of dairy products and red meat, similar to the link between...
