Men's Brains Age Faster
It's a fact that women live longer than men, and the latest figures, from 2023, show it's by an average of 5 years. Not fair! Then you will not be happy about this! Now a new study suggests that their brains age differently, with men's brains shrinking faster than women's.

The Brain Cleanup Crew
As older Americans become a larger part of our population, we'll see more people with Alzheimer's dementia. In the next 30 years, the cases will double unless we find a cure. Studies tell us AD is linked to the dysfunction of a brain protein called tau that gathers inside neurons. Another protein called beta-amyloid damages neurons by covering them, like plaque on your teeth. Scientists are now studying whether the cause of AD is that these proteins are piling up in the brain and cerebral spinal fluid because too few are being removed.

A New Tick Spit Protein is a Potent Immunomodulator
Behind mosquitos, ticks pose the greatest health risk to us among all creepy crawlies and animals. They can transmit microbes that cause serious diseases such as Lyme disease and babesiosis, an infection of red blood cells. Ticks pass on pathogens when they latch onto our skin using their mouths to feed on our blood. Proteins in their saliva immobilize our immune response, and scientists have been studying this mechanism for ways to manipulate it to our benefit.

Dementia and Super Agers
While Dave and I both want to age well, we don't know how much is out of our hands or how much damage has already been done. We'll discuss two studies on brain health to show that you can improve it - but only up to a point.

Attack on RNA Vaccines
One way to gauge the value of the COVID-19 vaccines is to calculate how many people would have been sickened and died without them. Just in the US, we would have had one and a half times more infections, nearly 4 times more people hospitalized, 4 times more deaths, and more than $1 trillion in added medical costs.
