Hunger Hormone Slows Aging in Mice


WIKIPEDIA, AYACOP Boosting levels of ghrelin, a hormone involved in hunger, keeps aging-related declines at bay in mice, according to a study published yesterday (February 2) in Molecular Psychiatry.

The authors gave mice a traditional Japanese medicine called rikkunshito or an extract from rikkunshito to stimulate hormone production. In three different mouse lines—two with shortened lifespans and another with a normal lifespan—the treatment resulted in the animals living longer.

“These findings suggest that the elevated endogenous ghrelin signaling has an important role in preventing aging-related premature death,” Akio Inui of Kagoshima University Graduate School of Medical and Dental Sciences and colleagues wrote in their report.

Scientists Assert That the WHO Should Classify Aging as a Disease

A group of scientists are calling on the WHO to classify aging as a disease, asserting that we need to create a better classification for what happens to our bodies as we get older.

A new controversy is brewing, as one group of scientists is recommending that aging be considered a disease.

Scientists from Insilico Medicine are highlighting the need to create a more granular and applied classification for what happens to our bodies when we age. Their work is outlined in a recent paper published in Frontiers in Genetics. The classification that they argue for is based on the World Health Organization’s (WHO) International Statistical Classification of Diseases and Related Health Problems (ICD-11), which is expected to be finalized in 2018.

Cloud-Brained Humanoid Robots Are Right around the Corner

As much as this article wants to promote that by 2020 that we will have terminator style robots acting as an in home nurse with patients (at least in the US) will be very hard to see. Most elderly as well as young children need more of human or personable interaction in their lives. I do highly suggest researchers (especially those that have studied children in orphanages where limited human interaction was available) to share your own insights of what happens to children who are without human contact at long periods as well as the elderly. I believe folks will rethink somethings and be more pragmatic in what these robots can and can do.

A new generation of humanoid robots are coming in the 2020s, says innovation and industry expert Alec Ross. They will care for our aging populations and revolutionize manufacturing. Ross’ book is “The Industries of the Future The Industries of the Future.

Collaborative Minds Bringing Sounds to Brain Data in Yearlong Project

Very huge step forward for brain sensory mapping.

Data from functional magnetic resonance imaging (fMRI) have provided eye-popping pictures of the way the brain is wired, and allowed neuroscientists and laypeople alike to view intricate anatomical and functional connections between regions of the brain. But what if a new tool could be applied to MRI and other data, to listen to the way the brain works and how it is forged with connections?

An emerging effort to “sonify” imaging data is taking root at UT Dallas’ Center for Vital Longevity, in the lab of Dr. Gagan Wig. The approach, now funded by the Defense Advanced Research Projects Agency (DARPA), allows data to be represented by sounds from which a trained listener might be able to discern patterns of brain connectivity not readily seen in available visualization strategies.

Wig, an assistant professor in the School of Behavioral and Brain Sciences, is working with his UT Dallas colleagues Dr. Roger Malina, Arts and Technology Distinguished Chair, Scot Gresham-Lancaster, assistant professor in the sound design program in the School of Arts, Technology, and Emerging Communication, and a mix of scientists, computer programmers and artists to translate data to sight and sound.

Mammal brain successfully returned from cryopreservation for the first time

A rabbit’s brain has been successfully returned from long-term cryogenic storage, marking the first time a whole mammalian brain has been recovered in near-perfect condition.

It marks a significant breakthrough in the field of cryonics and boosts the prospect of one day bringing frozen human brains back to life.

Researchers from 21st Century Medicine (21CM) used a new technique called Aldehyde-stabilized cryopreservation that filled the vascular system of the rabbit brain with chemicals that would allow it to be cooled to −211 degrees Fahrenheit (−135 degrees Celsius). When it was thawed, the cell membranes, synapses, and intracellular structures remained intact.

Brain Preservation Breakthrough Could Usher in a New Era in Cryonics

Researchers from 21st Century Medicine have developed a new technique to allow long term storage of a near-perfect mammalian brain. It’s a breakthrough that could have serious implications for cryonics, and the futuristic prospect of bringing the frozen dead back to life.

By using a chemical compound to turn a rabbit’s brain into a near glass-like state, and then cooling it to −211 degrees Fahrenheit (−135 degrees Celsius), a research team from California-based 21st Century Medicine (21CM) showed that it’s possible to enable near-perfect, long-term structural preservation of an intact mammalian brain. The achievement has earned not just accolades from the scientific community, but a prestigious award as well; the 21CM researchers are today being awarded the $26,735 Small Mammal Brain Preservation Prize, which is run by the Brain Preservation Foundation (BPF).
