According to a study published in the open-access journal Frontiers in Human Neuroscience, dancing can reverse signs of aging in the brain. The study also found that dancing showed greater results than other types of physical activity.
Dr. Kathrin Rehfeld, the lead author of the study, explained that “Exercise has the beneficial effect of slowing down or even counteracting age-related decline in mental and physical capacity. In this study, we show that two different types of physical exercise (dancing and endurance training) both increase the area of the brain that declines with age. In comparison, it was only dancing that lead to noticeable behavioral changes in terms of improved balance.”
The subjects in the study had an average age of 68 and were split off into two separate groups, one to test the effects of dancing and the other endurance training.
“We tried to provide our seniors in the dance group with constantly changing dance routines of different genres (Jazz, Square, Latin-American and Line Dance). Steps, arm-patterns, formations, speed, and rhythms were changed every second week to keep them in a constant learning process. The most challenging aspect for them was to recall the routines under the pressure of time and without any cues from the instructor,” Rehfeld said.
“Right now, we are evaluating a new system called “Jymmin” (jamming and gymnastics). This is a sensor-based system which generates sounds (melodies, rhythm) based on physical activity. We know that dementia patients react strongly when listening to music. We want to combine the promising aspects of physical activity and active music making in a feasibility study with dementia patients. I believe that everybody would like to live an independent and healthy life, for as long as possible. Physical activity is one of the lifestyle factors that can contribute to this, counteracting several risk factors and slowing down age-related decline. I think dancing is a powerful tool to set new challenges for body and mind, especially in older age,” Rehfeld added.
A different study conducted at McGill University’s Psychology Department has shown that music is actually more effective than drugs for a variety of different conditions. The study found that music can release natural chemicals and pain relievers in the brain that work quicker and better than drugs do. Prof. Levitin, one of the study’s main researchers explained how music can trigger chemical processes in the brain that have healing effects.
“We’ve found compelling evidence that musical interventions can play a healthcare role in settings ranging from operating rooms to family clinics. But even more importantly, we were able to document the neurochemical mechanisms by which music has an effect in four domains: management of mood, stress, immunity and as an aid to social bonding,” Levitin said.
The researchers found that music can release dopamine and opioids, cortisol, serotonin, and oxytocin. When these chemicals are released, they can improve motivation, increase pleasure derived from certain activities, which can help with eating disorders and other issues. These natural chemicals can also help with stress, social anxiety and improve immunity. Dr. Francis Chandra commented on the study, saying that these findings could encourage people to limit their dependence on other drugs.
“We know music facilitates active neurochemical processes in a symphony of opioids which pharmaceutical intervention has been unable to match. We’ve had residents where we could reduce psychotropic drugs or have them come off, and we could see benefits to staff with improvements in morale and engagement,” he said.
In one study, it was found that patients who listened to music before surgery had lower anxiety levels than people who were given anti-anxiety drugs like Valium or Xanax.
“The reviewed evidence does provide preliminary support for the claim that neurochemical changes mediate the influence of music on health. Music is among those lifestyle choices that may reduce stress, protect against disease, and manage pain,” the study said.
Most of the popular medications on the market today are simply catalysts to unlock the power chemicals that are already stored in our brains. To find natural ways to unlock these chemicals, can allow us to gain the benefits of those chemicals, without putting big pharma toxins into our bodies.

Cliffhanger: Mountain Biker Saved From “Imminent Death” After Falling Into Canyon
A Southern California mountain biker is likely counting his blessings after he was rescued from what authorities describe as “imminent death”” after falling from the side of a cliff in the Angeles National Forest.
The mountain biker, described as an older man, fell into the canyon at Mt. Wilson on Thursday morning and was dangling hundreds of feet above the ground before his fellow bikers, and eventually a special team from the Los Angeles County Sheriff’s Department, rescued him.
For some time the man dangled by a thin cord around his ankle that was tied to his bicycle while hanging on for dear life “like a cat,” Capt. Tom Giandomenico of the LASD special enforcement bureau told the Los Angeles Times.
“He knew he was in such a precarious situation. He was just scared to even rotate his head to look at us. He just didn’t want to move a muscle,” LASD Deputy Richard Thomsen told CBSLA.
Additionally, when the helicopter team arrived it wasn’t just a matter of simply hoisting the man to safety, as the air generated by the helicopter’s rotor would have sent the man plummeting to “imminent death,” Giandomenico added.
“Because he was head-down on the rock face there, that dropped probably a good 40 feet before it hit some soft dirt and a boulder,” Sheriff’s Deputy Scott Helbring said. “And beyond that was hundreds of feet down to the bottom of the canyon.”
Instead, one of the members of the special enforcement team composed of former SWAT officers devised a plan to rappel down to the man and move him to a ledge below, from which the two could be airlifted to safety.
However, due to a lack of boulders or trees, there was nothing to tie a rope to – and thus no way to rappel down to anything.
So instead, the special enforcement team used the man’s brother and another friend to be their anchor, a plan that ultimately succeeded.
Giandomenico called the rescue “one of the more significant, courageous maneuvers I’ve seen.”
“Heroic, in my opinion,” he added.
Scientists Create First-Ever Embryos With Monkey and Human Cells
For the first time, scientists have created embryos in a lab that contain the cells of both humans and monkeys.
Scientists hope that by creating chimeric embryos – embryos containing cells from two distinct species – they might be able to create organs for people who desperately need transplants.
Over 100,000 people in the United States lone are currently on a waiting list for organ transplants crucial to saving their lives, but the supply of donor organs has dropped significantly since the pandemic began unfolding.
Researchers have attempted to inject human stem cells into the embryos of pigs and sheep in recent years in hopes of growing organs for transplants, but this hasn’t yielded positive results. Scientists are hoping that by turning to macaque monkeys, which share a greater genetic similarity to humans, they may have more success.
In a study published Thursday in the journal Cell, researchers in the U.S. and China injected 25 pluripotent stem cells from humans into embryos from macaque monkeys.
After one day, the researchers detected human cells beginning to grow in 132 of the embryos. They embryos ultimately survived for 19 days.
However, bioethicists have raised concerns about the potential for abusing medical regulations that currently govern the treatment of animal and human subjects, as well as the possibility that a rogue scientists might potentially spike living creatures with human cells.
“My first question is: Why?” Kirstin Matthews, a science and technology fellow at Rice University’s Baker Institute, told NPR. “I think the public is going to be concerned, and I am as well, that we’re just kind of pushing forward with science without having a proper conversation about what we should or should not do.”
Researchers insist that the study serves purely humanitarian goals that could save countless lives in the future.
“This work is an important step that provides very compelling evidence that someday when we understand fully what the process is we could make them develop into a heart or a kidney or lungs,” said University of Michigan professor Jeffrey Platt, who was not involved in the study.
US Cop Shares Tiktok Video Showing How It’s Impossible To Confuse Taser for a Gun
In recent years, policing in the United States has received a much-needed reexamination, with many demanding changes to law enforcement or even its defunding and dismantling in light of high-profile killings committed by police officers.
However, one U.S. police officer has shared a video where he points out that in at least some fatal police encounters, simple common sense can save lives.
In a video shared to TikTok by user @brianb1504, the officer points out the differences between a pistol and a Taser. The video is a seeming response to the recent slaying of 20-year-old Daunte Wright by Minnesota police officer Kim Potter.
In the video, Officer Brian can be seen loading his belt with the firearm and less-lethal weapon, noting that his pistol is “dominant” while the bright yellow plastic taser is “not so dominant.”
“Huge weight difference, guys – I don’t understand how we can mistake a taser for a gun or a gun for a taser,” Brian continues.
“If you’re in the heat of the moment and you do something like that, you shouldn’t be doing this job,” he adds.
Continuing, Brian notes that he is sick and tired of the lousy state of police-community relations resulting from the actions of killer cops.
“I’m not going to put my life on the line to try and fix your stupidity and deal with restoring the peace with my public that I serve just because of your stupid actions,” Brian said.
“It makes no sense. 99 percent of our job is communication. You don’t have to be quick to pull out a gun or a taser on somebody and think everybody’s a threat,” he said. “Not everybody’s a threat. Try talking to them, get to know these people.”
While the account seems to have disappeared, it received upwards of 6 million views along with over 1.5 million likes and thousands of comments across the platform.
The video comes as the United States braces itself for more protests following the police killing of Daunte Wright by Kim Potter, a 26-year veteran of the Brooklyn Center Police Department. Police Chief Tim Gannon claims that Potter was trying to tase Wright but he died as a result of an “accidental discharge.”
Potter has since been charged with second-degree manslaughter. If convicted, she could face up to 10 years behind bars and/or a $20,000 fine.
