Study reveals those with frontotemporal dementia have greater white matter hyperintensity than those with other forms of dementia. The amount of white matter hyperintensity was associated with the severity of FTD symptoms.

Chronic increases of the cytokine IL-17a circulating in the blood of mice reduced microglia activity in one region of the hippocampus, an area of the brain critical for memory and learning.
Reverse Age

This is the FIRST part of the interview with Rodolfo Goya.
In this video Professor Goya talks about his role in the original experiment and the progress in his current study to reproduce the results with young blood plasma.
Professor Rodolfo Goya is Senior Scientist at The National Scientific and Technical Research Council in Argentina where he is a biochemist and researcher.
Dr. Goya has led a number of studies on cellular reprogramming and restoration of function in important organs, such as the thymus and the brain. He is also studying different aspects of cryopreservation.
He was one of the authors of the paper “Reversing age: dual species measurement of epigenetic age with a single clock” and is now working in his lab to reproduce and extend the results.
A study from the University of Wisconsin-Madison published on September 14 in Science revealed that when a plant is injured, they release a nervous system-like signal throughout their body, similar to the pain response found in humans and other animals.
When a human is injured, sensory cells in our bodies alert our nervous system to release the neurotransmitter glutamate. This stimulates a part of our brain to release adrenaline, which kicks our fight-or-flight response into gear. Plants don’t have nervous systems but video captured by the scientists behind this new study of injured plants shows that they do have their own version of fight-or-flight when they come under attack.
The footage captured by the study’s scientists shows a caterpillar eating away at a plant and the plant’s subsequent response. Because they lack a nervous system, plants don’t have neurotransmitters, but they do still have glutamate. In the video, a plant is bitten by a caterpillar and releases glutamate at the bite site. This activates a calcium wave to rush through the plant’s entire body, which then triggers the plant to release their own stress hormone.
When humans are under attack, our fight-or-flight reaction is triggered — and it turns out the same is true for plants too.
Summary: Prolonged anesthesia significantly alters the synaptic architecture of the brain, regardless of age.

While the brain tissue of modern humans are typically smooth and spherical, the study, which was published in Science on Feb 11, found that the tissue created with the ancient genes were smaller and had rough, complex surfaces.
“The question here is what makes us human,” Muotri told CNN. “Why are our brains so different from other species including our own extinct relatives?”
Summary: Study of people who are unable to feel touch reveals surprising new details about how we unconsciously embody our physical selves.

Experts say research raises deeper philosophical and ethical questions, creates grey area where animals were ‘not alive, but not completely dead’.
We all know the benefits of saunas on our mental and physical health, indeed, I recently did a video on just that, but what about the home saunas that are available so you can get the benefits as often as you desire, without having to leave the comfort of your own home, especially relevant in the current climate and recurring lockdowns… Well I have been testing both steam and infrared varieties extensively over the last year and have put together a quick guide on the pros and cons on both types. So if you have been thinking about investing yourself, or indeed you want to know which type is best for you, why not check out this video for further information. Have an awesome day…
Having already looked at the benefits of saunas, just how do home portable saunas stack up. Are they worth the expens…
