Recent experiments conducted in Boston labs have shown reverse aging results among mice and could show similar results in people.
The combined experiments — which were conducted during a span of 13 years — published Thursday (January 12) in the scientific journalCell reported that old, blind mice regained eyesight, developed smarter brains and built healthier muscle and kidney tissue, challenging the theory that DNA was the only cause of aging, as it proved that chemical and structural changes to chromatin played a factor without altering genetic code.
The research showed that a breakdown in epigenetic information caused the mice to age and the restoration of the epigenome reversed aging effects.
The concept of emergence is controversial to some — for example Eliezer Yudkowski, who favors reductionism, wrote a critique at Less Wrong (see link below). Do reductionists often dismiss emergence?
Talking points: EMERGENCE & REDUCTION, CONFUSION REGARDING EMERGENCE, LARGE SCALE NEUROSCIENCE PROJECTS, EMERGENCE AS A WAY OF EXPLAINING AWAY COMPLEXITY, IS CONSCIOUSNESS AN EMERGENT EFFECT? EMERGENCE & ARTIFICIAL INTELLIGENCE
The Attack of the Aliens from Vector Space: Steps Toward a Complex Systems Theory of Categorization and Similarity: http://www.goertzel.org/papers/catpap.html (Emergence & Compression) Extract: “The important concept of emergent pattern is defined: a pattern emerges between two entities if it is present in the combination of the two entities, but not in either of the entities separately. And the structural complexity of an entity is defined as the “total amount” of pattern in it. If the Metapattern is accepted, then these two concepts become essential to any analysis of biological reality.
We turn from these abstractions to a concrete biological example: the mammalian immune system. The theory of clonal selection states that immune systems evolve by natural selection; using the computer simulations of Alan Perelson, Rob deBoer and their colleagues as a guide, we inquire as to the exact nature of this evolution.
It goes without saying that if someone has a blood clot in their brain, that clot should be cleared as soon as possible. An experimental new transducer could help, as it uses swirling waves of ultrasound to break up blood clots much faster than existing methods.
Developed by scientists at North Carolina State University and the Georgia Institute of Technology, the device is designed specifically for use on what are known as cerebral venous sinus thrombosis (CVST) clots. These form in veins that ordinarily allow blood to drain from the brain. When those veins are blocked, blood pressure in the brain increases, to the point that a potentially lethal or disabling hemorrhage may occur.
Most existing CVST treatments involve using drugs to dissolve the clot. According to the team behind the new study, however, it takes an average of about 29 hours – and never less than 15 hours – for such medications to work. By contrast, the new transducer breaks up the clots in less than 30 minutes.

Understanding the neural interface within the brain is critical to understanding aging, learning, disease progression and more. Existing methods for studying neurons in animal brains to better understand human brains, however, all carry limitations, from being too invasive to not detecting enough information.
A newly developed, pop-up electrode device could gather more in-depth information about individual neurons and their interactions with each other while limiting the potential for brain tissue damage.
These specialized cells, once thought to merely insulate nerve fibers or maintain proper operating conditions for neurons, are now believed to play a significant role when it comes to understanding our surroundings. This breakthrough discovery was reported in the journal Nature Communications.
Alzheimer’s disease, which is the most common form of dementia, is challenging to treat. A possible therapy is deep brain stimulation delivered by a pacemaker-like device. A team of researchers from Charité – Universitätsmedizin Berlin discovered that stimulating a specific network in the brains of Alzheimer’s patients can decrease their symptoms. The study, published in the journal Nature Communications.
