Sensors introduce an important new method to spot bio-marker for brain diseases Accurate timings of when brain signals fire demonstrated for the first time by the Sussex scientists, which has implications for tracking the onset of brain disease The quantum brain sensors could present a more efficient and accurate alternative to EEG and fMRI scanners.

NIH launches program to map a rare type of non-dividing cells implicated in human health and disease
The National Institutes of Health has launched a program to study a rare type of cells, called “senescent” cells, that play both positive and negative roles in biological processes. The NIH Common Fund’s Cellular Senescence Network (SenNet) program will leverage recent advances in studying individual cells, or single-cell analysis, to comprehensively identify and characterize the differences in senescent cells across the body, across various states of human health, and across the lifespan. The rarity and diversity of these cells previously made them difficult to identify and study; therefore, a deeper understanding will help researchers develop therapies that encourage beneficial effects of senescent cells while suppressing their tissue-damaging effects.
“The number of senescent cells in a person’s body increases with age, which may reflect both an increase in the generation of these cells and a decreased ability of the aging immune system to regulate or eliminate these cells. This age-related accumulation of senescent cells leads to production of inflammatory molecules and corruption of healthy cells,” said Richard J. Hodes, M.D., director of the National Institute on Aging, part of NIH. “This can affect a person’s ability to withstand stress or illness, recuperate from injuries, and maintain normal brain function. The aim of NIH’s strengthened focus on this field of science is to one day conquer these and other challenges.”
A cell dividing into two cells is a hallmark of human development. Over time, our bodies accumulate a small number of cells that no longer divide. These “senescent” cells can play important roles in health, either directly or through the release of molecules that affect neighboring cells. Senescent cells can play positive roles, such as aiding wound repair or preventing tumor growth in some cancers. However, they can also contribute to chronic diseases of aging such as cardiovascular disease and neurodegeneration. For this reason, therapeutics called “senolytics” are being developed to target senescent cells and remove them from the body.
Neuroscience explains exactly why we should be grateful for…our brains
All these bequests of your bigger brain cortex mean you can gather four generations around a meal to exchange banter and gossip, turn information into knowledge and even practice the art of what-not-to-say-when.
You may even want to be thankful for another achievement of our neuron-crammed human cortices: All the technology that allows people spread over the globe to come together in person, on screens, or through words whispered directly into your ears long distance.
Making Tomorrow Better
I have a small YouTube channel which I create videos on clean energy and the environment. I have under 600 subs and many videos have not even hit 100 views but I am being increasingly targeted by fossil fuel activists and supporters, with personal attacks and misinformation.
I do respond to misinformation, and remove the worst comments but if anyone would like to help support me, nipping over to my channel, watching some videos and subscribing to the channel would be most appreciated.
We can show them that they are the minority, not us, and the wider the information spreads the quicker the change will be and the better life will be for everyone.
Thanks in advance and have an awesome day.
It is very likely that treatments to address the issues that cause aging & its related conditions & diseases will be within our reach in 15 to 20 years.
It is highly likely that a general realisation that these treatments are not only scientifically possible but within our reach will start to become increasingly apparent to the wider population in as little as maybe 5 years.
On this channel I will seek to hasten this realisation, & provide answers to the most common questions & concerns. I will also seek to distil the current scientific knowledge base into an easy to use action plan for those wishing to take measures to make sure they see this in good health.
To raise awareness of how close longevity treatments are.
NS/ The brain has a “compass” for navigating thoughts
Neuroscience biweekly vol. 46, 10th November — 24th November.
“It’s amazing that you can still find areas of the brain that are important for basic survival behaviors that we had never before implicated,” Betley says. “And these brain regions are important in robust ways.” The work, shared in the journal Nature, suggests that neurons in the cerebellum’s anterior deep cerebellar nuclei (aDCN) are involved in helping animals regulate their meal size. Since its start, Betley’s lab has unraveled a variety of neural circuits related to how the brain regulates food intake. That work as well as other research has implicated areas of the hindbrain and hypothalmus in this control.
Can quantum mechanics explain consciousness?
Well beyond Descartes and his mind-body duality, new questions have emerged that are as exciting as they are nebulous: Does quantum physics play a role in how the brain works? Or, more profoundly, is the mind, viewed as a collection of possible brain states, sustained by quantum effects? Or can it all be treated using classical physics?
There is nothing better than mixing two great mysteries to produce an even bigger one.
Natural selection has been acting on hundreds of human genes in the last 3,000 years
Natural selection, the evolutionary process that guides which traits become more common in a population, has been acting on us for the past 3,000 years, right up to the modern day, new research suggests.
And it seems to be acting in surprising ways on complex traits encoded by multiple genes, such as those tied to intelligence, mental illness and even cancer.
