Everything is perimenopause now – but what if it’s not?
Many of the signs of perimenopause can also be symptoms of other conditions, and some of these get increasingly dangerous if they’re misdiagnosed

Neanderthal-human hybrids may have been scourged by a genetic mismatch
When Homo sapiens and Neanderthals interbred, a genetic variation affecting red blood cells may have hindered reproduction in women who were hybrids, and this might have played a part in Neanderthals’ demise

mRNA covid vaccines spark immune response that may aid cancer survival
An analysis of patient records suggests that mRNA covid-19 vaccines boost the immune response to cancerous tumours when given soon after people start a type of immunotherapy, extending their lives
