After four billion years, the code of life has begun to shrink
The genetic code is billions of years old and contains the recipe for all life. Now scientists have managed to change it.
American researchers have given concrete estimates as to what extent physical activity is able to reduce the risk of breast and colon cancer. The goal is that doctors will one day prescribe physical activity to patients the same way as they do regular medication. However, Danish researchers are more hesitant.
Physical activity can prevent dementia in the elderly. But activities that stimulate the brain, such as reading, going to concerts or weeding the garden, also lower the risk of Alzheimer’s disease regardless of how much physical activity the person does, a Swedish study says.
Twenty-seven per cent of 75-year-old Swedish men and 10 per cent of 75-year-old Swedish women are considered to be hazardous drinkers, a new report says. Elderly people are more sensitive to alcohol than younger people and therefore are more at risk from drinking-related problems.
A recent study shows how mice can be made to prefer sickness, nausea, and stress over feeling well, just be removing one specific receptor from the brain. This could open the door to new treatments against various types of malaise associated with disease.
Sleep is one of those physiological necessities that continues to puzzle researchers. But a new study illuminates how missing one single night of sleep can initiate a series of physiological changes, and not necessarily for the better.
The general health of Greenlandic children now appears to be as good as that of their European peers. And perhaps even better. New studies show that compared with Danish children, they are no longer characterised as short and have similar patterns of disease.
Playing football is great for your health and could even stave off type 2 diabetes. New study in the Faroe Islands reveals improvements in overall health among middle-aged and elderly prediabetic men and women who enjoy a regular kickabout.
It’s a well-known phenomenon that a woman’s body temperature can help predict when she is least — or most —likely to become pregnant. Swedish researchers have studied this phenomenon and are selling a mobile phone app as a form of natural birth control. Their efforts are not without controversy.
