Medical notes this week…
A vaccine against dementia could be in human trials within a couple of years. A study on mice in the journal Alzheimer’s Research and Therapy shows that a treatment combining two experimental vaccines can successfully prevent the aggregation of amyloid and tau proteins in the brain. Those proteins are believed to be behind Alzheimer’s. Researchers say the vaccine also cleaned out protein aggregations in mice that already had them.
Computers are taking over a lot of functions… and reading mammograms may someday be one of them. A study in the journal Nature shows that specially trained artificial intelligence is more accurate than a doctor at reading mammograms to diagnose breast cancer… and just as accurate as two doctors working together. A-I reduced false negatives, where a cancer is missed, by nearly three percent… and cut false positives by more than one percent. Computers also never get tired.
And finally… just about everybody knows that the normal temperature of the human body is 98-point-six. except it’s not any more. According to a new study in the journal E-life, our average body temperature has been dropping for at least 150 years, probably because people expend less energy than they used to. This study doesn’t propose a “normal” temperature today… but another one a few years ago pegged it at 97.9.
