  Our body temperature may not get much hotter than 37°C, but inside our cells, the heat is more intense. Inside them, the temperature can reach scorching 50°C. Our cells “burn” food in oxygen to produce energy. Unlike a fire, this is a controlled process that involves several steps but still generates a lot of heat. Pierre Rustin and his colleagues at INSERM, a French public organization exclusively dedicated to biological, medical and public health research, used a dye developed by a group in Singapore to measure the temperature inside the mitochondria of human kidneys and skin cells kept at 38°C Ç. they discover argue that mitochondria operate at temperatures at least 6 to 10°C higher than the rest of the cell. While the French study is the first to look specifically at the temperature of mitochondria, another group made a similar finding in research with a different focus. An article published in February by a team in Japan describing another temperature-sensitive fluorescent dye b

To shield vulnerable patients from COVID-19, few people who work in health and long-term care would disagree with the ambition to vaccinate as many of their colleagues as possible. But there remain deep divisions over whether vaccination should be compulsory for staff who are not medically exempt. Share  In a special issue of the  BMJ , academics and a transplant patient debate the pros and cons of mandatory vaccination. “If hospital chefs refuse to comply with new safe food preparation guidance, they have no good reason to expect to continue to be employed,” argues Michael Parker , professor of bioethics at the University of Oxford, United Kingdom, in the BMJ. Trusted Source “So too in frontline healthcare roles, staff are rightly required to modify their practice in the light of evidence about patient safety,” he writes. Prof. Parker believes the same principle should apply to COVID-19 vaccination. Stay informed with live updates  on the current COVID-19 outbreak and visit our  coron
