Human stem cells used to cure renal anemia in mice

Posted by in categories: biotech/medical, neuroscience

(Medical Xpress)—A team of researchers with Kyoto University and Kagawa University, both in Japan, has cured renal anemia in mice by injecting them with treated human stem cells. In their paper published in Science Translational Medicine, the group describes their approach and how well it worked.

Chronic kidney disease is a serious ailment resulting in a host of symptoms due to the body’s reduced ability to process waste and fluids—many patients eventually experience , which requires them to undergo routine dialysis or a kidney transplant. Less well known is that people with also suffer from renal anemia because the kidneys manufacture the hormone erythropoietin (EPO), which causes the body to produce without which the blood cannot carry enough oxygen to the brain and other body parts. The current treatment for renal anemia is injections of EPO every few days, which, for many people, is impractical because of the cost and side effects. In this new effort, the researchers have found a possible new treatment—injecting treated directly into the kidneys.

In their experiments, the researchers collected stem cells from human cord blood (from the umbilical cord) and then treated them with growth factors that changed them to that grew into mature cells capable of producing EPO. The team then injected the treated cells into the kidneys of mice suffering from renal anemia and monitored them for the rest of their lives.

Anti-aging drug breakthrough

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

The work, published in the March 8 issue of Science, finally proves that a single anti-aging enzyme in the body can be targeted, with the potential to prevent age-related diseases and extend lifespans.

The paper shows all of the 117 drugs tested work on the single enzyme through a common mechanism. This means that a whole new class of anti-aging drugs is now viable, which could ultimately prevent cancer, Alzheimer’s disease and type 2 diabetes.

“Ultimately, these drugs would treat one disease, but unlike drugs of today, they would prevent 20 others,” says the lead author of the paper, Professor David Sinclair, from UNSW Medicine, who is based at Harvard University. “In effect, they would slow aging.”

Could DARPA’s Brain Uploads Lead To ‘Matrix’ Military Training?

Posted by in categories: government, military, neuroscience

With all the movies and TV shows currently streaming online, who has time to learn a new language or some other cognitive skill anymore? DARPA (the U.S government’s Defense Advanced Research Projects Agency) has been working on the ultimate cheat code for brains that would cut down the time needed to acquire knowledge and complete skill training. The program was not named after any of the characters from The Matrix, but it probably should have been.

According to Futurism, DARPA announced the Targeted Neuroplasticity Training (TNT) program back in 2016. In theory, DARPA would develop technology that would stimulate peripheral nerves to release more neuromodulators (brain chemicals) including acetylcholine, dopamine, serotonin, and norepinephrine. The chemicals would activate synaptic plasticity and the brain would be trained to process information for cognitive skills more quickly. The stated goal of TNT is to speed up training processes for military personnel and in turn reduce costs and improve results. “DARPA is approaching the study of synaptic plasticity from multiple angles to determine whether there are safe and responsible ways to enhance learning and accelerate training for skills relevant to national security missions,” said TNT Program Manager Doug Webe, in a press release. But the technology could be used for much cooler applications, like teaching me Jiu-jitsu or how to fly a helicopter in a matter of seconds.

The mystery of Stephen Paddock’s brain

Posted by in categories: biological, neuroscience

Stephen Paddock’s brother has speculated, “something went wrong in his head.” David Eagleman asks, what precisely was it? We know little about Paddock but quite a bit about biological factors that can be associated with violent behavior, Eagleman says”

“David Eagleman directs the Center for Science and Law and is an adjunct professor of neuroscience at Stanford University. He is the writer and presenter of the PBS series, “The Brain with David Eagleman,” and the author of the New York Times bestseller, “Incognito: The Secret Lives of the Brain.” The opinions expressed in this commentary are his own.”

‘In the wake of the mass shooting in Las Vegas, Stephen Paddock’s brother Eric speculated, “something went wrong in his head.” But what precisely was it?”

Brian Cox says we’ll soon upload our brains onto computers

Posted by in categories: computing, life extension, neuroscience, singularity

It may sound like the plot from the latest science fiction blockbuster, but uploading your brain onto a computer to achieve immortality could soon become a reality.

In a new interview, Professor Brian Cox said that the technique, known as ‘technological singularity’ could be available sooner than you think.

The Brain’s Meninges Harbour its Lymphatic System

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

By scanning the brains of healthy volunteers, researchers at the National Institutes of Health saw the first, long-sought evidence that our brains may drain some waste out through lymphatic vessels, the body’s sewer system. The results further suggest the vessels could act as a pipeline between the brain and the immune system.

Dr. Daniel S. Reich, Ph.D., M.D., discusses how his team discovered that our brains may drain waste through lymphatic vessels, the body’s sewer system.

To Combat Radical Violence in America, We Need Radical Medicine

Posted by in categories: biotech/medical, drones, government, neuroscience, security, terrorism

With yesterday’s terrible shooting tragedy, I’m hearing lots of calls for more gun control to reduce violence in the US. But that’s essentially impossible to accomplish. There are 300 million guns in America. Congress faces a statistical impossibility to make a real dent in gun control and possession (politicians saying otherwise are playing you for votes—the gov is not going to go house to house to collect guns). HOWEVER, better ways to combat terrorism and gun violence could be achieved through better medicine and figuring out better ways to keep wounded peope alive. We should focus our energy and science money on treating trauma victims (and also on prevention of mental disease and sociopaths). Also, drones can be designed to seek out shooters in public places in 30 seconds and stop what they’re doing (instead of letting them shoot for 10 minutes). Why don’t major public venues and events have them yet? Ask you government? Demand better responses so our society is safer. Also, entreprenuers, get out there and do something about this. Hotels would pay big money for see-through-wall technology that would alert staff that someone has 20 weapons in a room. Lots of this tech is already here. All these terrorism and gun violence issues can be best figured out by tech and science. Stop sending prayers, and instead send some engineers and technologists to solve the problems. This tragic ongoing violence will continue until tech and science solves it.


“If you make the human body virtually indestructible, being wounded loses some of its relevance.”

America is reeling in shock from multiple shooting tragedies. The national feeling is that the violence is increasing in frequency and there’s no end to the angst.

Freezing People After Heart Attacks Could Save Lives

Posted by in categories: biotech/medical, neuroscience

To reduce the damage to his brain and organs, Brooks was rushed to the University of Pennsylvania, where Dr. Lance Becker and his team cooled the young man’s core temperature to below 90 degrees Fahrenheit—a process called “induced hypothermia.” This is often done to cardiac arrest patients, either by injecting them with a cold saline solution or placing ice packs on them to increase their chances of complete recovery.

The dose of cold saved his life. Brooks had no brain damage, a remarkable feat that has led doctors to explore more ways to use induced hypothermia in emergency settings.

Now Dr. Sam Tisherman and his team at the University of Maryland, in collaboration with the University of Pittsburgh, plan to put 10 patients into a more severe form of hypothermia than what Brooks got, something known as “suspended animation.” They’ll flush their bodies with a cold fluid, cooling (and therefore preserving) tissue. The experimental trial, known as emergency preservation and resuscitation for cardiac arrest from trauma ( EPR-CAT), is funded by the U.S. Department of Defense, and it is the first time doctors are harnessing profound hypothermia (pushing body temperatures to as low as 50 degrees) to save lives.
