Brain tunes itself to criticality, maximizing information processing

Posted by in categories: biological, computing, neuroscience

Researchers long wondered how the billions of independent neurons in the brain come together to reliably build a biological machine that easily beats the most advanced computers. All of those tiny interactions appear to be tied to something that guarantees an impressive computational capacity.

Over the past 20 years, evidence mounted in support of a theory that the tunes itself to a point where it is as excitable as it can be without tipping into disorder, similar to a phase transition. This criticality hypothesis asserts that the brain is poised on the fine line between quiescence and chaos. At exactly this line, is maximized.

However, one of the key predictions of this theory—that criticality is truly a set point, and not a mere inevitability—had never been tested. Until now. New research from Washington University in St. Louis directly confirms this long-standing prediction in the brains of freely behaving animals.

Light 10 Billion Times Brighter Than the Sun Illuminates 2,000-Year-Old Herculaneum Scrolls

Posted by in categories: materials, neuroscience

Researchers led by the renowned ancient artifacts decoder, Professor Brent Seales, will be using Diamond, the UK’s national synchrotron science facility in the heart of Oxfordshire, to examine a collection of world-famous ancient artifacts owned by the Institut de France. Using this powerful light source and special techniques the team has developed, the researchers are working to virtually unwrap two complete scrolls and four fragments from the damaged Herculaneum scrolls. After decades of effort, Seales thinks the scans from Diamond represent his team’s best chance yet to reveal the elusive contents of these 2,000-year-old papyri.

Prof Seales is director of the Digital Restoration Initiative at the University of Kentucky (US), a research program dedicated to the development of software tools that enable the recovery of fragile, unreadable texts. According to Seales, Diamond Light Source is an absolutely crucial element in our long-term plan to reveal the writing from damaged materials, as it offers unparalleled brightness and control for the images we can create, plus access to a brain trust of scientists who understand our challenges and are eager to help us succeed.?Texts from the ancient world are rare and precious, and they simply cannot be revealed through any other known process. Thanks to the opportunity to study the scrolls at Diamond Light Source, which has been made possible by the National Endowment for the Humanities and the Andrew Mellon Foundation, we are poised to take a tremendous step forward in our ability to read and visualize this material.

Klotho: Queen of Anti-Aging Proteins

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

Klotho, named after one of the Fates of Greek mythology, is the queen of anti-aging proteins. There are no close contenders at this time. Klotho gene therapy, like the one offered by Integrated Health Systems, has tremendous benefits. While it is produced primarily in the kidneys and brain, its soluble form circulates throughout the body. Many of the investigations so far have been done nephrologists interested in its prominent role in Chronic Kidney Disease (CKD), yet over the last decade its multifaceted role in the aging process has become a topic of intense research.

Klotho deficient mice show premature aging in multiple organs.

Inducing KL overexpression with a viral vector, like AAV, not only reverses this premature aging, but also enhances resistance to oxidative and ischemic damage. More impressive, KL outright extends the lifespans of mice, likely be inhibiting IGF and insulin signalling. Dubbed an “aging suppressor gene,” it can yield results similar to caloric restriction – what is, at this time, the most tried and true method of extending the lifespans of a variety of model organisms.

New treatment under trial could restore brain cells in Parkinson’s

Posted by in categories: biotech/medical, neuroscience

A series of clinical trials have tested an experimental treatment for Parkinson’s disease that uses a novel approach: administering the drug straight into the brain via implanted ports. The leading researchers believe this may be a “breakthrough” therapeutic strategy for neurological conditions.

Newly trialed therapy could launch a fresh chapter in the treatment of Parkinson’s disease.

In a new series of studies that culminated with an open-label trial (where participants were aware of what treatment they would receive), scientists have begun testing the effectiveness of a new treatment — and method of delivery — for Parkinson’s disease.

An Oxford Neuroscientist Explains Mind vs. Brain

Posted by in category: neuroscience

It’s good to see a growing response to the materialist superstition about the mind and the brain from the neuroscience and philosophy community. Materialist theories of the mind are philosophically indefensible and scientifically discredited. Dualism is necessary to account for the immaterial nature of the intellect, for the metaphysical simplicity of the mind, and for free will. Of the varieties of dualism, I believe that Thomistic dualism offers the most satisfactory framework for neuroscience.

How Will We Store Three Septillion Bits of Data? Your Metabolome May Have the Answer

Posted by in categories: biological, computing, information science, neuroscience

For the “big data” revolution to continue, we need to radically rethink our hard drives. Thanks to evolution, we already have a clue.

Our bodies are jam-packed with data, tightly compacted inside microscopic structures within every cell. Take DNA: with just four letters we’re able to generate every single molecular process that keeps us running. That sort of combinatorial complexity is still unheard of in silicon-based data storage in computer chips.

Add this to the fact that DNA can be dehydrated and kept intact for eons—500,000 years and counting—and it’s no surprise that scientists have been exploiting its properties to encode information. To famed synthetic biologist Dr. George Church, looking to biology is a no-brainer: even the simple bacteria E. Coli has a data storage density of 1019 bits per cubic centimeter. Translation? Just a single cube of DNA measuring one meter each side can meet all of the world’s current data storage needs.
