Shooting electrical current into the brain for just 25 minutes reversed the decline in working memory that comes with aging, scientists reported on Monday. Although the researchers tested the effects on people for only 50 minutes, the finding offers hope for boosting a mental function that is so crucial for reasoning, everyday problem-solving, and planning
Diets that replaced red meat with healthy plant proteins led to decreases in risk factors for cardiovascular disease (CVD), according to a new study from Harvard T.H. Chan School of Public Health and Purdue University. The study is the first meta-analysis of randomized controlled trials examining the health effects of red meat by substituting it for
Americans spend more than a billion dollars on teeth whitening products each year. Although these products can make smiles brighter, new research shows that they might also be causing tooth damage. In three new studies, researchers found that hydrogen peroxide, the active ingredient in over-the-counter whitening strips, can damage the protein-rich dentin tissue found beneath the tooth’s protective enamel.
The kidneys filter waste and water from blood. People with kidney failure can use a dialysis machine to filter blood. It removes blood from a vein in the arm, filters it outside the body, and returns clean blood to another part of the vein. If dialysis is needed often, the vein becomes more likely to
Orgenesis Inc., a developer, manufacturer and service provider of advanced cell therapies, today announced that it has entered into a collaboration agreement with Digilab Inc. to develop a live cell printing process and systems designed to automate the production of three-dimensional live cellular structures and tissues. Under the Agreement, Orgenesis will have the exclusive rights
Telemedicine is a relatively new concept that allows healthcare providers to treat patients via the Internet through varying technology platforms, such as FaceTime or Skype. While the practice initially started as a means for healthcare providers to treat patients in rural or remote areas who were far away from local health facilities or in areas
It was once a central tenet of biology that RNA molecules did their work inside the cell. But it’s now clear that RNA molecules are also active outside the cell, with potentially major implications for our health. To learn more about these unrecognized roles, the NIH Common Fund has launched the Extracellular RNA (exRNA) Communication Program. This month,
The discovery of insulin in the 1920s marked the breakthrough in the almost 3,500-year-long mystery of diabetes, a disease first described in ancient Egyptian papyruses. Until its discovery, physicians struggled to explain how symptoms such as sugary urine, constant thirst and frequent urination could lead to ailments ranging from blindness and nerve damage to coma
More and more, we are using special industrial 3D printers, with inkjet and aerosol jet technology, to embed conductive components within our intelligent products in what we call 3D printed electronics. Items like ECG electrodes and contactless payment cards use these embedded components to perform wireless activities and readings, like measuring the frequency of a person’s heart beats
A new analysis published on 3 April in the Lancet links 20 per cent of global deaths to poor diet, equating to around 11 million deaths per year (1). The biggest risk factors were a high intake of sodium (salt) or low intake of whole grains, fruit, nuts and seeds, vegetables, and other healthy foods. The Global Burden of Disease
