Researchers discover the Achilles’ heel of an aggressive brain cancer
Posted by Paul Battista in categories: biotech/medical, neuroscience
Researchers from the University of Helsinki have discovered a chink in the armour of the tumour cells of glioblastoma, a lethal brain cancer. Alongside the finding, the researchers also came up with a method for attacking this vulnerability. The results gained in experiments conducted with cell cultures and a mouse model are promising.

LATE: A Disease That Mimicks Alzheimer’s Disease
Posted by Steve Hill in categories: biotech/medical, life extension, neuroscience
A recent article, published in the Oxford journal Brain, categorizes and draws attention to an age-related disease that impacts the brain yet is widely unknown, even among scientists: limbic-predominant age-related TDP-43 encephalopathy (LATE) [1].
The symptoms of this disease are similar to those of Alzheimer’s disease. It causes cognitive impairment and, when presenting alongside Alzheimer’s disease, can lead to even faster degeneration along with heightened agitation and aggression.
This new disease has been found to impact very specific areas of the brain – generally traveling vertically through the brain, it degenerates areas partly responsible for emotions, memory, and language, influencing different areas depending on its stage.

Detecting dementia’s damaging effects before it’s too late
Posted by Quinn Sena in categories: biotech/medical, health, neuroscience
Scientists might have found an early detection method for some forms of dementia, according to new research by the University of Arizona and the University of Toronto’s Baycrest Health Sciences Centre.
According to the study published in the journal Neuropsychologia last month, patients with a rare neurodegenerative brain disorder called Primary Progressive Aphasia, or PPA, show abnormalities in brain function in areas that look structurally normal on an MRI scan.
“We wanted to study how degeneration affects function of the brain,” said Aneta Kielar, the study’s lead author and assistant professor in the UA Department of Speech, Language and Hearing Sciences.

Awakening stem cells to unlock the brain’s regenerative potential
Posted by Paul Battista in categories: biotech/medical, chemistry, neuroscience
The human body has powerful healing abilities. But treating brain disorders is no easy task, as brain cells—neurons—have limited ability to regenerate. Nonetheless, stem cells are a form of natural backup, a vestige of our days as still-developing embryos.
The difficulty is that with age, neural stem cells ‘fall asleep’ and become harder to wake up when repairs are needed. Despite efforts to harness these cells to treat neurological damage, scientists have until recently been unsuccessful in decoding the underlying ‘sleep’ mechanism.
Now, researchers at Kyoto University studying brain chemistry in mice have revealed the ebb and flow of gene expression that may wake neural stem cells from their slumber. These findings, which may also apply to stem cells elsewhere in the body, were recently published in the journal Genes & Development.

The Entropic Enigma of Ouroboros’ Metamorphosis
Posted by Alex Vikoulov in categories: energy, neuroscience
Antonin Tuynman: Where we see complexity, we see high informational content, organised in a complex way which often involves hierarchical levels. The diversity in highly complex systems might at first glance seem a chaotic mixed bag and hodgepodge; it is not. The diversified apparent mishmash is not a sign of apparent chaos, where you’d expect high thermodynamic entropy. It is not the stifling rigidity of a perfect order either. Complexity is an intricate architecture of stacked and intertwined hierarchical levels, with multifarious information exchanges between them. In fact Complexity selects the best of Order and Chaos. This seemingly ordered chaos or chaotic order, brings us the gift of the ability to ever introduce new variations. An ability to regenerate, copy, multiply and spread itself. An ability to induce ever changing patterns to adapt itself to the circumstances. An ability of recursive self-modification.

The mighty worm Ouroboros had lost trace of its path and didn’t know its whereabouts. Nor did it know where it was going. In fact it didn’t know anything anymore, as it had drunk from the Lethe, Hades’ river flowing though Hypnos’ caves. Drinking from Lethe, forgetfulness and daughter of Eris, Goddess of Strife and Discord, made one lose all memory of past existence.
Disoriented Ouroboros started turning, and by continuing to turn, it finally found a trail of what seemed to be a path. A tasty object lay there, waiting to be eaten, and as Ouroboros bit it, a painful jolt of energy shot through its body awakening all the memories it had forgotten. Abruptly Ouroboros awoke from its dreamtime of daze and stupor and recognized itself as the ever effulgent Consciousness, Creator of Macrocosm and Microcosm.

New Treatment May Have the Potential to Slow, Stop, or Reverse Parkinson Disease
Posted by Paul Battista in categories: biotech/medical, neuroscience
Results from a recent study suggest that a revolutionary treatment may have the potential to slow, stop, or even reverse the progression of Parkinson disease.
Results from a February study of a revolutionary treatment suggest that it may be possible to slow, stop, or even reverse the progression of Parkinson disease, according to findings in the Journal of Parkinson’s Disease.
The 3-part, experimental study investigated whether using a novel delivery system to increase levels of glial cell line-derived neurotrophic factor (GDNF) can regenerate dying dopamine brain cells in patients with Parkinson disease and even reverse their condition. GDNF is a naturally occurring protein that promotes the survival of many types of neurons.

Neuroscientist Dr Hannah Critchlow: ‘Changing the way that you think is cognitively costly’
Posted by Genevieve Klien in categories: biotech/medical, food, neuroscience
The concept of fate is often used in the context of love and choosing a partner. In your book, you talk about a study that give a scientific explanation for the idea that “opposites attract”. A panel of men was asked to wear a T-shirt for several nights and days and they weren’t allowed to wear deodorant or eat anything too smelly. The T-shirts were presented to an array of women who were asked to sniff then and rate them in terms of attractiveness based purely on smell. It turns out that the females rated the males as more attractive if their MHC [major histocompatibility complex] systems were different from their own, because then their offspring would have a stronger immune system, a better range of armoury against potential infections. So women were kind of sniffing out Mr Right.
What else does neuroscience tell us about a successful relationship? If you image the brains of the couples who have been together for a long, long time and ask them to think about their partner, their brain will react in the same way as a drug addict’s. You can almost say this couple are addicted to each other.
You say “affection is a neurochemical event” – that’s not very romantic. Valentine’s Day with me is a lot of fun!
