Harvard Medical School scientists report they have successfully restored vision in mice by turning back the clock on aged eye cells in the retina to recapture youthful gene function.
The team’s work, described Dec. 2 in the publication Nature, represents the first demonstration that it may be possible to safely reprogram complex tissues, such as the nerve cells of the eye, to an earlier age.
In addition to resetting the cells’ aging clock, the researchers successfully reversed vision loss in animals with a condition mimicking human glaucoma, a leading cause of blindness around the world.
Let’s say you hate 5G and genuinely believe it causes cancer or spreads COVID-19, despite there being no evidence to support those wild conspiracies. To shield 5G’s myriad evils, then, you put your WiFi router in a metallic box that “blocks about 90 percent” of the signal. There! Now you’re instantly protected from those treacherous waves of radiation!
This may sound like a made-up scenario, but 5G truthers really have bought these devices in droves. There’s just one small problem with their fool-proof plan: The kinds of containers that truly do block all electromagnetic radiation are called Faraday cages, and they’re not the same thing as these so-called “router guards” that look like glorified mesh file organizers. If they were real Faraday cages, none of your home WiFi signal would come through.

Brain Muraresku, author of “The Immortality Key — The Secret History Of The Religion With No Name”, discussing his fascinating journey to discover psychedelic potions from antiquity, reconstruct their history in the development of religion and civilization, and their development into a modern neuro-pharmacopoeia.
On today’s show we are going to be weaving together a really interesting range of themes including psychedelics, pharmacognosy and medicinal botany, history, religion & spirituality, end of life care, dreaming, mental health and a whole lot more.
Brian Muraresku is the author of “The Immortality Key: The Secret History of the Religion with No Name”.
Brian graduated Phi Beta Kappa from Brown University with a degree in Latin, Greek and Sanskrit. As an alumnus of Georgetown Law and a member of the New York Bar, he has been practicing law internationally for fifteen years.
He is also founding executive director of Doctors for Cannabis Regulation. Their work has been featured on CNN and ESPN, as well as The Washington Post and San Francisco Chronicle. In arbitration with the NFL in 2018, Mr. Muraresku represented the first professional athlete in the United States to seek a therapeutic use exemption for cannabis.
Just a few doses of an experimental drug can reverse age-related declines in memory and mental flexibility in mice, according to a new study by UC San Francisco scientists. The drug, called ISRIB, has already been shown in laboratory studies to restore memory function months after traumatic brain injury (TBI), reverse cognitive impairments in Down Syndrome, prevent noise-related hearing loss, fight certain types of prostate cancer, and even enhance cognition in healthy animals.
In the new study, published Dec. 1, 2020, in the open-access journal eLife, researchers showed rapid restoration of youthful cognitive abilities in aged mice, accompanied by a rejuvenation of brain and immune cells that could help explain improvements in brain function.
“ISRIB’s extremely rapid effects show for the first time that a significant component of age-related cognitive losses may be caused by a kind of reversible physiological “blockage” rather than more permanent degradation,” said Susanna Rosi, PhD, Lewis and Ruth Cozen Chair II and professor in the departments of Neurological Surgery and of Physical Therapy and Rehabilitation Science.
Ineurals — advanced neuro-technologies for rapid learning and skill acquisition.
The 711th Human Performance Wing, under the U.S. Air Force Research Laboratory leads the development, integration, and delivery of Airman-centric research, education, and consultation enabling the U.S. Air Force to achieve responsive and effective global vigilance, global reach, and global power now and in the future. It’s comprised of the United States Air Force School of Aerospace Medicine and the Airman Systems Directorate, whose science and technology competencies include Training, Adaptive Warfighter Interfaces, Bioeffects, Bioengineering, and Aerospace and Operational Medicine.
The Individualized Neural Learning System, or iNeuraLS, is a new augmented learning platform that will enable rapid learning by closed-loop modulation of cognitive states during skill acquisition. Essentially, the AFRL team seeks to develop a capability that will give Airmen the ability to rapidly acquire knowledge and skills on the fly through direct brain interfaces with the help of neurotechnologies.
And we have not 1, but 2 fascinating guests on the show with us today:
Dr. Nathaniel Bridges serves as the Neural Interfaces Team Lead within the Air Force Research Laboratory’s Cognitive Neuroscience Section. In this role, he and his team seek to find and enable ways to link the human brain/nervous system with technology in a manner that will benefit the Air Force. This in part relies on testing and evaluating current and emerging Brain Machine/Computer Interface technologies for the Air Force and investigating the impact of various neuromodulation technologies on cognitive performance. Dr. Bridges has his PhD. in Biomedical Engineering, from Drexel University, in Philadelphia, PA USA.
Dr. Gaurav Sharma, a member of the scientific and professional cadre of senior executives, is the Senior Scientist for Cognitive Neuroscience, 711th Human Performance Wing. He serves as the principal scientific authority and independent researcher in the field of cognitive neuroscience and is in charge of initiating, planning, coordinating, evaluating and conducting research and development that increases the Air Force capabilities relative to this critical technological area. Dr. Sharma has his PhD. in Mechanical Engineering, from Northeastern University, in Boston, MA, USA.
At-risk Coloradans might get the first doses of a COVID-19 vaccine as soon as next week.
In an interview with Colorado Matters on Friday, Gov. Jared Polis said the Pfizer vaccine would be made available first, followed a few weeks later by the Moderna vaccine. Both vaccines require two doses with 30 days in between.
“We are only hopefully a week away from the first highly effective vaccine arriving at our state,” he said. “And I would encourage anybody just to look at the data on the efficacy of this vaccine — 90 percent, 94 percent, there’s two of them.”
