Scientists Are Developing New Ways to Treat Disease with Cells, Not Drugs

Posted by in categories: biotech/medical, neuroscience

While blood stem cells from bone marrow have long been a cornerstone of treating blood cancers like leukemia and lymphoma, Mackenzie’s trial extracting the cells from a pregnant woman to treat a developing fetus in utero is just one of several innovative uses of stem cells to treat a growing list of diseases with cells instead of drugs. And promising studies are inching more of these stem-cell-based treatments closer to finally being tested in people.

With stem cells like those found in bone marrow, scientists are taking advantage of what the body does naturally: generate itself anew. Many of the adult body’s organs and tissues, including fat cells and blood, are equipped with their own stash of stem cells whose sole job is to regenerate cells and tissues when older ones are damaged or die off and which can be harvested for research and growth outside the body.

Some organs are not endowed with these large stem-cell reservoirs, however, most notably the brain and heart muscle. So more than two decades ago, scientists found another source of these flexible cells–in embryos that were donated for research from in vitro fertilization clinics. They learned how to grow these cells in the lab into any cells in the body. That opened the possibility that conditions like heart disease, diabetes or even psychiatric disorders might eventually be treated by replacing damaged tissues or organs with healthy ones, which could provide cures and treatments that didn’t require drugs or surgery.

Exercise Induces Adult Neurogenesis and Ameliorates Alzheimer’s Disease in Mice

Posted by in categories: biotech/medical, genetics, health, neuroscience

A new study on adult neurogenesis and Alzheimer’s disease.


According to a study led by scientists at Massachusetts General Hospital, exercise-induced neurogenesis improves cognition in a mouse model of Alzheimer’s disease, yielding more benefits than drug-induced adult neurogenesis. The scientists were able to figure out the difference between the two types of induced neurogenesis and pharmacologically reproduce the same benefits provided by exercise [1].

DARPA Wants Brain Interfaces for Able-Bodied Warfighters

Posted by in categories: biotech/medical, military, neuroscience

The Next-Generation Nonsurgical Neurotechnology (N3) program will fund research on tech that can transmit high-fidelity signals between the brain and some external machine without requiring that the user be cut open for rewiring or implantation. It hasn’t escaped DARPA’s attention that no-surgery-required brain gear that gives people superpowers may find applications beyond the military. The proof-of-concept tech that comes out of the N3 program may lead to consumer products, says Justin Sanchez, director of DARPA’s Biological Technologies Office. “This will spawn new industries,” he says…


The N3 program will create no-surgery-required neurotech that the general public may also find useful.

Gene involved in circadian rhythms can be potential target for glioblastoma treatment

Posted by in categories: biotech/medical, neuroscience

Researchers have discovered a way to kill #cancer cells and stop #glioblastoma formation by blocking casein kinase 1 gene.


Scientists with the Virginia Tech Carilion Research Institute say a gene involved in the body’s circadian rhythms is a potential target for therapies to help patients with a deadly form of brain cancer known as glioblastoma.

This discovery, to be published in the journal Scientific Reports on Tuesday, Sept. 11, points to a subtype of a particular gene that apparently is enabling the survival of cancer cells, although it is more commonly associated with circadian rhythms — the body’s 24-hour biological clock.

One of the Most Famous Degenerative Diseases Affects the Brain in Previously Unknown Ways

Posted by in categories: biotech/medical, health, neuroscience

An incurable affliction that gradually destroys a person’s ability to walk, speak, and eventually breathe can also deteriorate the mind, new research suggests. People with amyotrophic lateral sclerosis (ALS) are more likely to have other mental and behavioral health problems than people without the condition, the study found.

ALS, also called Lou Gehrig’s disease, is a progressive neurologic condition that affects some 20,000 Americans at any one time. In ALS, a person’s motor neurons throughout their body and brain steadily die off. These neurons are responsible for helping us carry out voluntary movement.

The Augmented Posthuman Body

Descartes once described the human body as a “fleshy machine” and today’s transhumanists would likely agree.

Philosopher Nick Bostrom writes that as we seek to peer farther into posthumanity our ability to concretely imagine what it might be like trails offend that the very essence of posthumanity is to be able to have thoughts and experiences that we cannot readily think or experience with our current capacities.

Researchers Identify Molecule With Anti-Aging Effects On Vascular System

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

ATLANTA—A molecule produced during fasting or calorie restriction has anti-aging effects on the vascular system, which could reduce the occurrence and severity of human diseases related to blood vessels, such as cardiovascular disease, according to a study led by Georgia State University.

“As people become older, they are more susceptible to disease, like cancer, cardiovascular disease and Alzheimer’s disease,” said Dr. Ming-Hui Zou, senior author of the study, director of the Center for Molecular and Translational Medicine at Georgia State and a Georgia Research Alliance Eminent Scholar in Molecular Medicine. “Age is the most important so-called risk factor for human disease. How to actually delay aging is a major pathway to reducing the incident and severity of human disease.

”The most important part of aging is vascular aging. When people become older, the vessels that supply different organs are the most sensitive and more subject to aging damage, so studying vascular aging is very important. This study is focused on vascular aging, and in old age, what kind of changes happen and how to prevent vascular aging.”
