Brett Anderson, MSG, MSW — Journey From Rock Musician To Rethinking Aging, Longevity & Mental Health

Posted by in categories: biotech/medical, business, life extension, neuroscience

Is a Gerontologist and Clinical Social Worker on a mission to rethink aging, longevity & mental health.

Ms. Anderson was also the former lead singer of the American Rock group, The Donnas (https://en.wikipedia.org/wiki/The_Donnas), where she was the lead vocalist for 20 years, performing throughout the U.S., as well as internationally, and had performances / appearances on major network shows including Saturday Night Live, David Letterman and Late Night with Conan O’Brien.

New Molecule Destroys Alzheimer’s-Causing Amyloid Tangles

Posted by in categories: biotech/medical, neuroscience

A molecule found in green tea helped UCLA biochemists in the discovery of multiple molecules capable of destroying tau fibers.

University of California, Los Angeles (UCLA) researchers used a molecule present in green tea to uncover more molecules that may break up protein tangles in the brain, which are known to cause Alzheimer’s.

Alzheimer’s disease is a disease that attacks the brain, causing a decline in mental ability that worsens over time. It is the most common form of dementia and accounts for 60 to 80 percent of dementia cases. There is no current cure for Alzheimer’s disease, but there are medications that can help ease the symptoms.

Impaired Kidney Function Linked to Cognitive Disorders

Posted by in categories: biotech/medical, neuroscience

Summary: Of patients with dementia, 7% had chronic kidney disease while 9% had albuminuria, a urinary marker for kidney disease. Chronic kidney disease was associated with a 51% increased risk of developing dementia.

Source: American Society of Nephrology.

New research has demonstrated a link between kidney disease and the development of cognitive problems.

Brain Complexity and Consciousness

Using the EBRAINS research infrastructure, scientists of the Human Brain Project have developed multi-scale simulations of the human brain that mimic hallmarks of activity during wake and deep sleep states. Such simulations can lead to a better understanding of biological mechanisms that regulate human consciousness and its disorders, which span from single neurons to whole brain scales.

ROME: Locating and Editing Factual Associations in GPT (Paper Explained & Author Interview)

Posted by in categories: computing, neuroscience

Large Language Models have the ability to store vast amounts of facts about the world. But little is known, how these models actually do this. This paper aims at discovering the mechanism and location of storage and recall of factual associations in GPT models, and then proposes a mechanism for the targeted editing of such facts, in form of a simple rank-one update to a single MLP layer. This has wide implications both for how we understand such models’ inner workings, and for our ability to gain greater control over such models in the future.

Supported Cell Therapy for Parkinson’s Disease is Entering Clinical Trials

Posted by in categories: biotech/medical, neuroscience

A major hallmark of Parkinson’s disease is the loss of dopamine-producing neurons in the brain, which in turn causes patients to lose motor control abilities. NYSCF – Robertson Stem Cell Investigator Alumna Malin Parmar, PhD, of Lund University, has spent a decade developing a cell therapy to replace these cells, and this revolutionary treatment (called ‘STEM-PD’) has just received approval for a Phase I/IIa clinical trial in Sweden.

“We are excited and looking forward to this clinical study of STEM-PD, hoping that it could potentially help reduce the significant burden of Parkinson’s disease. This has been a massive team effort for over a decade, and the regulatory approval is a major and important milestone,” said Dr. Parmar, who is a Professor of Developmental and Regenerative Neurobiology at Lund, in a statement.

Dr. Parmar’s innovative work towards a Parkinson’s cell therapy earned her the NYSCF – Robertson Stem Cell Investigator Award in 2016, which provided support for her lab’s research until 2021, including her work on STEM-PD.

Ken Hayworth’s personal response to MIT Technology Review article

Posted by in category: neuroscience

This is my rebuttal to the recent MIT Technology Review article by Michael Hendricks. The views expressed here are mine alone and should not be taken as an official statement from the BPF which is an organization with a diverse range of opinions but a common goal to advocate more scientific research into brain preservation…

The next wave of regenerative medicine

Posted by in categories: biotech/medical, life extension, neuroscience

Regenerative medicine company Frequency Therapeutics is developing new drugs that activate our innate abilities to restore function and reverse degenerative diseases. The company is working on small molecules that selectively activate progenitor cells already present within our bodies to create healthy, functional tissues. Frequency’s initial focus is on hearing loss and multiple sclerosis, and the company has just completed enrolment of a Phase 2b trial in adults with acquired sensorineural hearing loss (SNHL).

Longevity. Technology: Frequency is focused on progenitor cells, which are like stem cells but can only make cells that belong to the same tissue or organ. While progenitor cells remain active in some of our organs and tissues, they can become dormant in others. Frequency’s small molecules are designed to selectively target and induce dormant progenitor cells to create specific cell types to restore tissue structure and function. We caught up with Frequency’s Chief Scientific Officer Dr Chris Loose to learn more.

Nasdaq-listed Frequency was founded in 2014, licensing technology developed by professors Robert Langer from MIT and Jeffrey Karp from Harvard Medical School.

“Unexpected” — Scientists Discover an Anti-Aging Mechanism

Posted by in categories: biotech/medical, life extension, neuroscience

A multinational team headed by University College London scientists has discovered a new mechanism that slows down and maybe even prevents the normal aging of immune cells, one of the nine “hallmarks of aging.”

The discovery in-vitro (cells) and validated in mice was “unexpected,” according to the researchers, who believe harnessing the mechanism might extend the life of the immune system, enabling people to live healthier and longer lives, and would also have therapeutic use for diseases such as cancer and dementia. Their findings were recently published in the journal Nature Cell Biology.

Explaining the study, lead author, Dr. Alessio Lanna, Honorary Professor at UCL Division of Medicine, said: Immune cells are on constant high-alert, always ready to fight pathogens. To be effective they also must persist for decades in the body – but the strategies employed to execute this life-long protection are largely unknown.
