“Humans are considered uniquely susceptible to Alzheimer’s disease, potentially due to genetic differences, changes in brain structure and function during evolution, and an increased lifespan. However, a new study provides the most extensive evidence of Alzheimer’s disease brain pathology in a primate species to date. Researchers found that the brains of aged chimpanzees, our closest living relatives, show pathology similar to the human Alzheimer’s disease brain.”
There is new research on the brain and Alzheimer’s from Kent State University that is quite eye opening and interesting. The study analyzed the brains of elderly chimpanzees our closest relatives whom we share about 98% of our DNA with. What they found was pathology in the chimp brains similar to what we see in humans suffering from the disease.
Estimates are that about 1/3 of people over age 65 suffer from some form of dementia in the USA and the most common cause of this dementia is Alzheimer’s. This disease is a progressive disease and it is irreversible. It results in impaired cognitive functioning and behavior changes including aggressiveness and combativeness in some patients. Genetic differences are attributed to explaining just why humans are so susceptible to the disease including changes in brain structure and functioning and researchers believe this is connected to our evolution and increased life span. However, this new research shows something similar also happens in the brains and functioning in elderly chimps! Continue Reading
No matter where I’ve been in the wilds I have never gotten lost. Sound strange? I’m not the only one! Be it in wilds that I know or that I don’t know I’ve always known what direction to go to get back to my starting point or wherever I wanted to go and this is what we might call our “internal compass” at work and there is scientific proof for such an ability.
Back in 2014 University College London conducted a study using fMRI (functional magnetic resonance imaging) and found the part of the brain that tells us the direction to travel when we navigate around. The strength of the signal predicts how well we can navigate, which means, those with strong signals tend to navigate better than those with low signals.
Some people are better navigators than others but up until this study we really didn’t know why. This study showed that the strength and reliability of our inner “homing signals” vary among people and predict our navigational skills. Some people tend to get lost a lot and this is because the strength of their directional or “homing” signal is weak (like my grandfather who was forever getting lost in the wilds!). Continue Reading
This new research presented today on how Maple Syrup extract may boost the potency of antibiotics without damaging our health is not only fantastic but NATURAL! Native Americans in Canada have been using maple syrup for fighting infections for a long time as well. More natural medicine!

A few new studies appear today that I find highly interesting. The first concerns a study from the University of Toronto that shows too much structured knowledge hurts creativity and, frankly, I couldn’t agree more. Of course structure helps us organize our activities throughout the day and it helps us to understand the world around us BUT it can also kill creativity! Structure tends to box us in and we might want to try thinking “out of the box” more. This leads me back to “everything in moderation” as it appears from the finds of this study too much of a good thing (structure) is not good when it comes to creativity. I’ve seen this over and over again. We are indoctrinated in our education and tend to then wear blinders as if we are looking through a tunnel (tunnel vision). We can see what’s in the tunnel before us but not what is on the sides of the tunnel. This increase in structure explains why creativity has gone down in modern society and education today. You’ll find the study results at the link below.
Another study focuses on aging and DNA repair. This study comes from the Harvard Medical School. They found that as we age the body has a harder time repairing DNA which causes cell demise (body degeneration) and greater susceptibility to cancers and other diseases. This study also shows that treatment with the NAD precursor NMN mitigates age-related DNA damage and “wards off DNA damage from radiation exposure. This study is significant because it helps us understand the aging process better and may help us come up with better anti-aging strategies or at least help us battle age-related diseases.
The final study comes from John Hopkins Medical School. This study found that most cancer mutations are due to random DNA copying errors. They found that at least 2/3 of these mutations cause cancers. Each times a cell divides and copies its DNA it produces two new cells and sometimes it makes several mistakes. These copy mistakes foster cancer mutations that science has underestimated in the past. Of course, environmental factors such as smoking also cause cancers but researchers have mostly been at a loss to explain why people who don’t smoke and seem to do everything right still get cancer. These DNA copy mistakes could very well be the reason! The bad news to all this is that even in people who do everything right and still get cancer it seems there is no stopping it as it is caused by these DNA copy errors. More research is needed into this and as soon as possible I’d say! Hmmm….let me guess….we’ll blame it on our Neanderthal bad genes???? 🙂

It’s been snowing in the Middle East in such places as the United Arab Emirates and also in the Sahara (for the first time in about 37 years) in case you haven’t been paying attention to the news lately. That’s pretty bizarre! Now comes a new study from the University of California in Santa Barbara saying the oceans are absorbing more CO2 and that this has been going on for the past decade. What that means is that LESS of this GREENHOUSE GAS is going into the atmosphere and thus slowing global warming meaning global cooling may be happening! Rising levels of CO2 in the oceans is thought to be caused in part by a slowing of the ocean’s overturning circulation. This, frankly, could spell BAD NEWS for us!
Some scientists have said that global warming due to CO2 in the atmosphere may be a blessing as it may be slowing down ice age conditions on planet Earth. Of course these scientists are mocked and marginalized by the man-caused global warming gang who continue to push their agenda that man is the major cause of such warming. Of course then we have NASA and NOAA being caught redhanded a few days ago fudging temp data from Central Africa claiming it is the hottest in that area it’s ever been! Yet people in Central Africa say it is NORMAL and come to find out neither NASA or NOAA have anything beyond a few thermometers in the region to begin with! LIARS!! CHARLATANS!!
Now returning to my subject at hand………….the ocean’s circulation is slowing down and the effect is keeping more CO2 in the ocean which means less CO2 is going into the atmosphere and thus means warming has slowed for the past 10 years or more and that means cooling.
Now of course it is thought that ice ages develop due to changes in the earth’s rotation which is not stable like we think. These wobbles are known as the Milankovitch Cycles. The earth’s rotation wobbles like a gyroscope and this alters the amount of solar radiation that hits the earth. Further, the earth’s orbit around the Sun is NOT a perfect circle like some think but is instead elliptical and varies over time. Further, keeping in mind that we are ALREADY IN AN ICE AGE known as the Quaternary Period at present for the past 10-12 thousand years we’ve been in a warming period and common sense along with geologic history tells us that SOMEDAY the ice WILL return. Is that now? Continue Reading
New DNA evidence suggests that infectious diseases have been around a lot longer than we previously thought at it is also suggesting that humans coming out of Africa may have infected Neanderthals who likely did not have a natural immunity to the diseases. Although this did not cause Neanderthals to go extinct it certainly would have contributed to it.
Cortez arriving in Mexico City
When Cortez and his Spaniards invaded Mexico the Mexica (Aztecs) had no natural immunity to the diseases like smallpox that they carried with them. Thousands of Mexica died of smallpox and other diseases that Europeans had natural immunity to. The same scenario played out in the US and South America when Europeans arrived and native populations became infected causing thousands of deaths. So it is no stretch of the imagination to see how Homo sapiens coming out of Africa could have brought infectious diseases with them to which the Neanderthals had no natural immunity and resulted in their demise.
This new information comes from Dr Charlotte Houldcroft published in the American Journal of Physical Anthropology. She suggests that H. sapiens coming out of Africa would have been a “significant reservoir of tropical diseases.” She goes on to suggest that such disease infecting the Eurasian Neanderthals would have been catastrophic. This would have tipped the balance of their survival. She further suggests the scenario may not have played out like it did when Cortez or Columbus came to the Americas but I think she is likely wrong about that assumption. I think that it is HIGHLY likely that it did play out in the SAME pattern as that of Cortez and Columbus when they came to the Americas.
Finally some evidence and theory that makes sense as to what the fate of the Neanderthals was instead of the mythical theory that they just sort of disappeared into thin air!!!
