One of the Most Famous Degenerative Diseases Affects the Brain in Previously Unknown Ways
Posted by Genevieve Klien 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.

DARPA Next-Generation Neurotechnology and breakthroughs from Neuralink and Open Water Red light scanner
Posted by Klaus Baldauf in categories: Elon Musk, neuroscience
DARPA is funding development of high resolution brain interfaces. At the same time there are two companies who have breakthrough technology for higher resolution brain interfaces. The two companies are Elon Musk’s Neuralink and Mary Lou Jepsen’s Openwater red light scanner. The Neuralink and Openwater systems will be described after the DARPA project and its goals.

Researchers Identify Molecule With Anti-Aging Effects On Vascular System
Posted by Manuel Canovas Lechuga 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.”

The Alzheimer’s Hypothesis
Posted by Nicholi Avery in categories: biotech/medical, neuroscience
A detailed analysis of Alzheimer’s disease.
Alzheimer’s disease was first discovered in 1907 in a 51 year old woman by the German physician Alzheimer. One of the first changes noticed was an eruption of jealous feelings towards her husband. It wasn’t long before symptoms of rapid memory impairment were observed. The impairments prevented her from finding her way out of her home, She hid herself, she would drag objects to and fro, and occasionally screamed because she believed people were out to kill her.
When she was institutionalized her gestures would show a complete helplessness. As common in most Alzheimer’s patients, she was disoriented as to time and place. At times she would state that she didn’t understand anything, felt confused, and totally lost. When the doctor came in to see her she would consider it as an official visit and would apologize for not having finished her work. Other times she would be terrified and start to yell that the doctor wanted to operate on her. Other times she would send him away in complete indignation uttering phrases indicating that she was afraid that the doctor wanted to damage her woman’s honor. At times she would become completely delirious, dragging her blankets and to and fro, calling for her husband and daughter, and seeming to experience auditory hallucinations. She would often scream for hours and hours in a horrible voice. Mental regression advanced quite steadily. After four and a half years of illness the patient finally died.

DARPA’s New Brain Chip Enables Telepathic Control of Drone Swarms
Posted by Genevieve Klien in categories: computing, drones, military, neuroscience
The US military’s Defense Advanced Research Projects Agency (DARPA) has created a brain-computer interface that enables a person to control everything from a swarm of drones to an advanced fighter jet using nothing but their thoughts and a special brain chip.
Life imitates art, in defense tech no less than in society. In the 1982 techno-thriller film “Firefox,” Clint Eastwood steals a fictional Soviet fighter jet called the “MiG-31 Firefox,” a Mach 6-capable stealth fighter he piloted with his thoughts. But now in 2018, the US military has gone even further: you can control a whole group of drones or fighter jets with your thoughts.
