A flexible and transparent power source inspired by the electric eel could be used to power electrical devices in the body, such as cardiac pacemakers, implantable sensors or even prosthetic organs. The prototype, described in Nature1 on 13 December, runs on a solution of salt and water, but researchers hope that future versions might get their energy from bodily fluids.
There is no proven intervention for preventing late-life dementia. Researchers from the Minnesota Evidence-based Practice Center (EPC) reviewed published research to determine if physical activity, prescription medications, over-the-counter vitamins and supplements, or cognitive training interventions could help to prevent dementia in patients who did not have it at the time of the studies. The vast majority of research showed that none of the interventions worked. Findings from four systematic evidence reviews are published in Annals of Internal Medicine.
Around the world, lists of patients in need of an organ transplant are often longer than the lists of those willing (and able) to donate — in part because some of the most in-demand organs for transplant can only be donated after a person has died. By way of example, recent data from the British Heart Foundation (BHF) showed that the number of patients waiting for a heart transplant in the United Kingdom has grown by 162 percent in the last ten years.
Researchers at Queen’s University in Canada have managed to get a special type of bacteria to swim against a strong current, opening up the possibility of using the organisms as drug delivery vehicles. The team is using magnetotactic bacteria which have magnetic crystals within them and naturally orient themselves with the Earth’s magnetic field. By setting up the external magnetic field, the researchers were able to coax the bacteria to move in predictable ways and directions.
Sometimes even the experts need a little help staying holly and jolly. Research shows holiday season stress can feel insurmountable. No one is immune. Mental health professionals, who are usually helping others manage emotions, put their own advice into practice as the year winds down.
Boehringer Ingelheim has initiated GioTag, a real-world study to assess the impact of sequential therapy in patients with EGFR mutation-positive (M+) advanced non-small cell lung cancer (NSCLC). Data from approximately 190 patients who received tyrosine kinase inhibitors (TKI) – afatinib* in first-line, followed by second-line osimertinib**as part of standard clinical practice – will be analysed to determine total time on treatment.
