Researchers have discovered why inflammaging occurs and are working on new treatments. Inflammaging is new medical term for “the chronic inflammation brought on by old age.”
Summary: Inflammaging is a low-grade inflammation brought on by old age. It accelerates the aging process and worsens diseases like cancer and heart disease. Because inflammaging accelerates aging, geroscientists are perfecting a few cures for the condition.
As we age, most of us tend to develop a low-grade chronic inflammation that causes disease and damage throughout the body. Because this low-level inflammation typically accompanies aging, scientists have nicknamed it ‘inflammaging.’ Most geroscientists implicate inflammaging as the cause of many of age-related diseases including diabetes, heart disease, cancer, and dementia. These chronic diseases accelerate aging and shorten our lives.
There is good news, however. Geroscientists feel that reducing inflammaging will eliminate or reduce these diseases. In fact, these anti-aging scientists have developed several potential remedies to solve the problem.

(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 renal failure, which requires them to undergo routine dialysis or a kidney transplant. Less well known is that people with chronic kidney disease also suffer from renal anemia because the kidneys manufacture the hormone erythropoietin (EPO), which causes the body to produce red blood cells 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 stem cells 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 pluripotent stem cells 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.

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.”

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.

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.”

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.
Professor Cox said that he found ‘no reason at all’ why human intelligence couldn’t be simulated by computers — although he did not express a timeline for this to happen.

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.
